Building ESG and Decarbonisation Reporting: Build or Buy?
The threshold is roughly 40 assets in a single country with mostly landlord paid utilities. Below it, buy: Measurabl covers that portfolio well, Deepki covers it well in Europe, and a custom build is an expensive way to reproduce a maintained product.

The threshold is roughly 40 assets in a single country with mostly landlord paid utilities. Below it, buy: Measurabl covers that portfolio well, Deepki covers it well in Europe, and a custom build is an expensive way to reproduce a maintained product. The sharper test is whether data acquisition has become a permanently staffed function rather than an annual push, because acquisition is the programme in this category and not a setup step. A portfolio of 100 assets served by four suppliers is a smaller build than 40 assets served by thirty. Above that line a first release runs $70,000 to $150,000 over 14 to 20 weeks, and net lease owners who never see a meter should build nothing at all.
When is off the shelf genuinely the right call here?
Buy if you hold under roughly 40 assets in one country, your leases are mostly landlord paid so meter access is straightforward, and your obligation is a benchmark submission plus an annual investor deck. Measurabl covers that well and Deepki covers it well across European markets. Both sell data collection as a service and both do it competently within their supplier coverage. Reproducing a maintained product to reach the same place is poor value, and we will say so on the call.
Buy EnergyCAP if your actual question is bill auditing and utility cost control rather than carbon boundary. It is genuinely strong at that, and it is a different problem from portfolio emissions reporting. Buy Arc Skoru if what you need is scoring and certification rather than portfolio wide acquisition. Keep ENERGY STAR Portfolio Manager for the assets that need a score regardless of what else you run.
And build nothing if you are a net lease owner who genuinely never sees a bill. Your problem is a lease negotiation, not a software project, and no system will produce data a tenant has no obligation to give you. Spend the money on green lease clauses and, where the local utility offers it, on whole building aggregated data requests.
The evaluation that separates a fit from a workaround is not the feature list. Hand a vendor your utility account register and ask which accounts they can acquire automatically, which need a portal credential, and which they will not cover. If the uncovered share is small, buy. If it is a third of your floor area, you have found the reason people build.
When does a custom build actually pay off?
Build when two or more of these hold.
- You operate across enough utility markets that acquisition is a permanently staffed function. A portfolio of 60 assets can carry 400 utility accounts across 30 suppliers, split between landlord accounts, house accounts held by a managing agent, and tenant accounts you have no legal visibility into.
- You hold assets under two or more building performance standards with real penalty exposure. New York Local Law 97, Boston BERDO and the Washington Clean Buildings Act each apply their own covered building definitions, cap schedules and calculation methods.
- Investors or lenders have started asking asset level questions rather than portfolio level ones, so every figure has to be defensible individually rather than in aggregate.
- You are allocating retrofit capital off the same data and the model needs to sit beside the asset business plan rather than inside a reporting tool.
- You have restated more than once and the credibility cost has reached the board.
From Digital Heroes delivery experience: a first release covering utility account onboarding with explicit state per account, bill and interval capture including document extraction, provenance and coverage tracking, a versioned area and boundary model, a factor library and an investor or submission ready export runs $70,000 to $150,000 over 14 to 20 weeks. A full platform adding performance standard penalty modelling, retrofit pathway scenarios, tenant data request workflow, target tracking and assurance ready evidence packs runs $180,000 to $450,000 phased over 8 to 14 months.
How do they compare on the things that matter in this industry?
Provenance on every value. The most damaging habit in portfolio reporting is mixing measured and modelled consumption in the same cell, because once that happens coverage becomes an opinion. Every consumption record should carry its method, whether measured, estimated by degree day regression, extrapolated by area or supplied by tenant, plus the input that drove it. Coverage is then computed by asset, fuel, month and floor area rather than asserted.
Boundary and denominator. Two teams holding identical meter data can publish intensities differing by 30 percent through boundary and area choices alone. Whole building against landlord controlled. Gross internal against net lettable. Whether vacant space and car parks are in scope. Storing consumption once at meter level with scope tagged, and computing every reported figure as a view over it, is what stops three workbooks drifting apart within a quarter.
Area versioning. Buildings get remeasured, and a remeasurement should never silently rewrite five years of intensity history. Ask any product whether floor area carries an effective date.
Factors as data. Grid factors are revised and a new vintage restates years you already published. Factors need a source, a vintage, a geography and an effective period, with every emission figure recording which version produced it, so recalculation is a job you run with a difference report rather than an archaeology exercise. Dual reporting under the Greenhouse Gas Protocol Scope 2 guidance also means instruments attach to specific consumption in specific periods, so a certificate cannot be applied twice.
Restatement handling. Ask any developer or vendor how a previously published figure stays retrievable after a correction. If that answer is missing, you will discover it in front of your assurance provider.
What does total cost of ownership look like at your scale?
A worked example. A fund holding 61 assets across two countries, roughly 400 utility accounts spread over 30 suppliers, a mix of landlord paid and tenant metered space, and 18 assets under a building performance standard.
First release: discovery including an audit of the account register $12,000, data model covering account, meter, service period and consumption record with method and provenance $24,000, bill document extraction with reconciliation against the prior bill so overlapping or missing days surface $22,000, interval ingestion into a time series store $15,000, versioned floor area with configurable boundary rules $17,000, factor library supporting dual Scope 2 reporting $18,000, computed coverage $11,000, investor and submission export with an evidence pack behind every figure $13,000, and two years of historic backfill with testing $11,000. That totals $143,000. A 25 asset single country portfolio with landlord paid utilities across three suppliers lands nearer $75,000.
Adding performance standard modelling for the 18 covered assets at $35,000 to $80,000, retrofit pathway scenarios, tenant data request workflow and assurance evidence packs takes the same fund to roughly $300,000 to $400,000 in total across the following year.
Running costs. Support and enhancement at 12 to 18 percent of build cost a year, weighted towards enhancement while new jurisdiction rules are added. Document storage in the low hundreds of dollars a month at that portfolio size, growing permanently because bill images are the evidence behind published figures. And the staffing nobody quotes: supplier portals break, credentials expire and formats shift, so somebody owns that task queue every month, and the extraction correction queue needs an owner because new suppliers produce layouts the extraction has not seen.
Against that, measure three things on your side. The weeks of senior time absorbed each year by data assembly and rebuilding a submission workbook. The number of restatements across the last three cycles. And modelled penalty exposure on covered assets across your hold period, which is the figure that moves this out of the reporting budget and into the capital budget.
What does the hybrid look like, and when is it the honest answer?
The most common sensible hybrid is not one system, it is a division of labour. Keep the vendor for the accounts it acquires cleanly, keep ENERGY STAR Portfolio Manager where a score is required, and build the layer that owns the chain nobody else owns: utility account through meter through bill line through factor through denominator to the published number. That is the join a sustainability lead currently maintains in a workbook in March.
The thinnest useful build is acquisition and provenance alone at $40,000 to $70,000 over nine to twelve weeks: account state tracking, bill extraction with service period reconciliation, and coverage computed rather than asserted. It will not produce a submission on its own. What it does produce is the answer to the question an investor will eventually ask, which is what share of your reported consumption is backed by measured data. Most portfolios cannot answer that today, and knowing it changes what you are willing to commit to publicly.
Two scoping decisions keep the hybrid honest. Start with the assets carrying a regulatory obligation, usually about a third of the portfolio and most of the risk. And start any utility whole building data request process before development begins, because those approvals run on a timeline you do not control and frequently outlast the build.
The hybrid stops being honest when retrofit capital allocation is the real objective. Scenario modelling needs a clean measured baseline underneath it or it produces confident nonsense, so it belongs in phase two after acquisition is working, not bolted onto a vendor export.
Which should you choose, by operator size and stage?
Under 40 assets, one country, landlord paid, benchmark plus investor deck. Buy Measurabl or Deepki. Build nothing. Revisit if tenant metered floor area grows or a second jurisdiction brings a performance standard.
Net lease owner with no meter visibility. Buy nothing and negotiate. Green lease data sharing clauses and utility aggregated data requests are the whole answer here, and a system would only relabel your estimates.
40 to 80 assets, several utility markets, restatements happening. Start with acquisition and provenance at $40,000 to $70,000. Audit your account register first, which costs a week of an analyst's time and removes the largest unknown from any estimate you receive.
Multi market portfolio with two or more performance standards. Build the first release at $75,000 to $143,000 depending on supplier count and country footprint, then phase penalty modelling and retrofit scenarios. Confirm which assets are covered with counsel rather than with an article, including this one.
Fund allocating retrofit capital off the same data. Phase to the full platform at $180,000 to $450,000, with the pathway model attached to each covered asset and output shaped for an investment committee rather than a sustainability report. That framing is why these programmes survive a cost cutting cycle.
In every case, own the repository, the database and the cloud accounts in writing. Your historical consumption record is the evidence base behind figures already in the market.
If you want that decision made properly rather than quickly, Digital Heroes contracts through India LLP, US LLC and UK LTD entities, so the agreement and the intellectual property assignment sit under law your own advisers already read. You keep the specification either way.

Frequently asked questions
What does it cost to move off our current ESG platform?
The licence is the small part. The real cost is your historical consumption record and the evidence behind it, because those figures are already published and you may need to defend them years later. Ask what a full export contains, specifically whether it includes bill images, the method behind every estimated value, and the factor version applied to each published figure.
If the export is final numbers only, that is a material exposure independent of price. Also confirm what re establishing supplier portal credentials involves, since that work sits with your asset managers and managing agents rather than with software.
What if our vendor raises prices or changes the pricing basis?
Get the renewal figure and the basis it is quoted on, whether per asset, per meter or per square foot, and project it across your hold period rather than one year. Per meter pricing in particular scales in ways that surprise portfolios adding submetering, which is exactly what a decarbonisation programme encourages you to do.
The protection is portability rather than a build. Confirm the export contents at renewal, keep your utility account register authoritative on your own side, and know which accounts sit outside the vendor's coverage so you are not negotiating from a position where the data is trapped.
How long does a first release take?
Fourteen to 20 weeks. The schedule risk is almost never engineering, it is utility account onboarding, because collecting account numbers, letters of authority and portal credentials across dozens of suppliers involves your asset managers and their managing agents rather than the development team.
Portfolios holding a clean utility account register move noticeably faster than those starting from a shared drive of documents. Auditing that register before kickoff costs a week of analyst time and shortens everything downstream.
Is Measurabl cheaper than building our own?
Considerably, and for a portfolio under roughly 40 assets in one country with mostly landlord paid utilities it is the right answer. You are buying a maintained product plus a data collection service.
Where it becomes limiting is accounts outside its supplier coverage, tenant metered space as a large share of floor area, and retrofit capital modelling that needs to sit beside the asset business plan. Test it by handing over your account register and asking which accounts it acquires automatically and which it will not cover at all.
How much does building performance standard modelling add?
Typically $35,000 to $80,000 depending on how many jurisdictions apply. Each standard is its own rule set, since covered building definitions, cap schedules and calculation methods differ, so two jurisdictions is close to double one rather than a configuration change.
What justifies it is a modelled penalty exposure across your hold period with retrofit measures the asset team can toggle. That is a capital planning artefact rather than a compliance report, and it is the version an investment committee will actually read.
Why is data acquisition most of the budget rather than a setup task?
Because there is no general solution. Some suppliers publish a machine readable feed, some run a portal with a short history window and a challenge screen, some only post a document. Each route is separate work and the thirtieth is not cheaper than the third.
Every account also needs explicit state: a source, a method, a last successful read date and an owner, so that a broken portal raises a task rather than producing a silent gap that becomes an estimate in March.
Can we start with the smallest useful scope?
Yes. Acquisition and provenance alone runs $40,000 to $70,000 over nine to twelve weeks: account state tracking, bill extraction with service period reconciliation so overlapping or missing days surface, and coverage computed by asset, fuel and floor area.
It will not produce a submission on its own. It will tell you what share of your reported consumption you can actually defend, which most portfolios cannot answer today and which tends to change what people commit to publicly.
Do we still need our assurance consultant if we build this?
Yes, and for assurance you certainly do. What changes is what their hours go on. A system holding evidence per figure, keeping previously published values retrievable through a restatement, and recording the method behind every estimate turns an assurance cycle from reconstruction into review.
Ask any developer how they handle a restatement before you sign. If keeping the previously published figure retrievable is not part of the answer, they have not been through an assurance cycle and you will find out in front of your auditor.
When is it time to move from Excel reports to an actual dashboard?
The reliable signal is when someone spends more than a few hours a week copying data between spreadsheets, or when two teams arrive at a meeting with different numbers for the same metric. At that point the spreadsheet is acting as an unversioned, single-person database, and a costly error is a matter of time. A first dashboard that automates those recurring reports typically pays for itself in recovered hours within the first year.
Should I hire a freelancer or an agency for my software project?
A skilled freelancer is the right call for a single-discipline scope under roughly $15,000, like a website, a plugin, or one integration. Above that, projects need design, backend, testing, and project management at once, and a solo builder becomes the single point of failure: if they get sick or take a bigger client, your project simply stops. Agencies bill 20-40% more per hour but carry continuity, code review, and someone to escalate to, which is what you are actually buying.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.
Is custom software more secure than off-the-shelf SaaS?
Neither is secure by default; security tracks the practices of whoever builds and operates the system, not the model. SaaS gives you the vendor's certifications and patching but puts your data in a shared multi-tenant platform on their terms, while custom gives you full control over data residency, access rules, and compliance requirements like HIPAA, with the responsibility sitting with you and your agency. Before hiring anyone for a system holding sensitive data, ask for their security checklist: encryption at rest and in transit, an OWASP Top 10 review, role-based access, and a penetration test before launch.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
How many people should be working on my software project?
Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.
Can I build my product on a no-code tool like Bubble instead of hiring developers?
For testing whether anyone wants the product, yes, and Bubble's paid plans start at $29 a month, which is the cheapest validation you will ever buy. The ceiling arrives with complex data relationships, heavy integrations, performance at a few thousand users, and the fact that you cannot export a Bubble app to servers you control. A path many Digital Heroes clients take: prove demand on no-code, then rebuild custom once revenue justifies it, treating the no-code version as a paid prototype rather than a foundation.
Can one dashboard pull from QuickBooks, Salesforce, and Google Analytics at the same time?
Yes, and combining sources like that is the main reason to build custom instead of living inside each tool's built-in reports. The standard pattern syncs each source into one warehouse using connectors such as Fivetran or Airbyte, then joins them there, so marketing spend, pipeline, and revenue finally sit in a single view. Each additional source typically adds 1 to 2 weeks to the build, mostly for field mapping and reconciliation.
How do I work out whether a custom dashboard will pay for itself?
Add up three numbers: hours of manual reporting it removes each month, license seats it replaces or avoids, and the value of one or two decisions it speeds up, like catching margin slippage a month earlier. Across Digital Heroes projects, internal dashboards typically pay back in 8 to 18 months, and customer-facing dashboards pay back faster when analytics is a paid feature or reduces churn. If the honest math does not clear payback within 2 years, buy an off-the-shelf tool instead.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
What questions should I ask a development agency on the first call?
Ask who exactly will build it, what happens when scope changes mid-project, what their maintenance terms are after launch, and what they will need from you every week. Then ask them to describe a project that went wrong and what they changed afterward; teams that have shipped at real volume have war stories, and teams claiming a perfect record are hiding something. The scope-change answer matters most: a disciplined shop describes a written change-order process, not a vague promise to be flexible.
Do I need a data warehouse before building a custom dashboard?
Not for a small build; a dashboard reading from 1 or 2 sources can query them directly or use a plain Postgres database as its store. You want a real warehouse like BigQuery or Snowflake once you are joining 3 or more sources, keeping history beyond what source systems retain, or serving many concurrent users. Adding the warehouse costs around 2 to 4 extra weeks and is usually the single best investment in the project's future.
Who can build a custom business intelligence dashboards system?
Digital Heroes builds custom business intelligence dashboards systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other business intelligence dashboards companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
