The test takes two hours. List every deal in the portfolio whose valuation currently lives outside the system, and total the notional and the optionality sitting in that list. If your book is mostly vanilla forwards and financial swaps and that list is short, buy Molecule and stop there. If the deals carrying most of your optionality are the ones held as free text with a spreadsheet beside them, the build that pays is not a replacement platform but a $150,000 to $350,000 valuation and risk layer alongside what you already run. Full custom, at $500,000 to $1,200,000, is right for a narrow set of firms and wrong for most.
When is off the shelf genuinely the right call here?
Buy if your book is mostly vanilla forwards and financial swaps. The valuation is standard, the risk decomposition is standard, and nothing about those positions justifies bespoke quantitative work. Firms in that position who build usually do so because they dislike a vendor rather than because their deals demand it, and they end up owning a maintenance obligation for a capability they could have licensed.
The products worth naming, and who should be buying them:
- Molecule. It has genuinely changed the mid market. Fast to deploy, cloud native, a modern interface, and for a straightforward power and gas book it is a strong purchase that many firms should make instead of anything custom. It is opinionated, which is exactly why it deploys quickly.
- ION Openlink Endur. The enterprise standard, and it earns that on breadth. For a large multi commodity trading house it remains the default and a custom replacement would be an act of self harm.
- Allegro. Similar profile inside the same group with particular depth in gas and power. The same weight considerations apply in both directions.
- Amphora and Enuit. Credible mid market options with real capability and smaller ecosystems, which matters mainly when you need people who already know the system.
- Aspect Enterprise Solutions. Deepest heritage in oil and refined products. For a power and gas portfolio it is a less natural fit than the alternatives above, which is a fit question rather than a quality one.
Whatever you do, buy the plumbing. Trade capture for vanilla instruments, confirmations, basic settlement and the general operational machinery are commodity capability. Rebuilding them is expensive and gains you nothing.
When does a custom build actually pay off?
Four signals, and the first is close to decisive on its own.
Your structured deals sit in the system as placeholders. A tolling agreement entered with a notional and a comment, valued weekly in a workbook by one analyst, using a curve pulled by hand. When the risk report reaches the committee, the position with the most convexity in the portfolio is a number that is four days old and cannot be traced to a source. That spreadsheet is your real risk system, it has one author, and it is a stronger argument than any feature comparison.
Your curve methodology lives on a laptop. How you blend broker quotes with market settlement history, derive basis at an illiquid node, shape a monthly block into hourly and bridge the gap between the liquid horizon and a twelve year tenor is the firm's own intellectual property, and often the reason the firm makes money. Concentration in one analyst is a risk in the same sentence as a control weakness.
Credit exposure is produced monthly by hand. The failure mode is never the arithmetic, it is timing. Exposure moves through a threshold during a price spike and nobody calls for collateral for three weeks.
The unexplained residual in your daily profit and loss is lumpy. When it is consistently small the risk committee trusts the book. When it is not, every meeting becomes an argument about data rather than about the position.
How do they compare on the things that matter in this industry?
Template fit for negotiated contracts. Vendor deal templates are built around instruments that repeat across many clients, which is the right product decision and the reason your vanilla book works. Tolling agreements with availability tests, storage with injection and withdrawal ratchets and cycling limits, transport with fuel retention varying by path, load following supply with a bandwidth penalty, heat rate calls struck against two commodities: each is a genuinely different valuation problem. Forced into a user defined field, they sit inside the system without participating in it.
Curve construction ownership. Every packaged system ships a curve manager. What it manages is curves someone else builds. The construction methodology is the part that is yours, and the question a practitioner can test is whether you can reproduce a mark from last March with the inputs and the methodology version that produced it.
Credit timing. Exposure netted under the agreement in force, plus potential future exposure over remaining tenor, adjusted for collateral held and posted, thresholds and independent amounts, changes with every curve move. Recalculating on every curve publication and enforcing limits at deal capture is a contained piece of engineering with an unusually direct payoff.
Attribution as a storage decision. Decomposing the daily move into curve movement, new deals, actualisation, settlement adjustments and residual is not a report you bolt on. It determines how positions and valuations are stored, so it is far cheaper to build in than to retrofit.
Pace of extension. This is the verifiable criticism of the enterprise incumbents. Extension runs through the vendor's own scripting environment and specialist consultants, so small changes take longer than the business expects. That is tolerable when your deal population is stable and a genuine constraint when your desk structures something new each quarter.
What does total cost of ownership look like at your scale?
A structured deal valuation and risk layer covering curve construction, the deal types the template cannot hold, credit exposure under your netting and collateral terms, and attribution the risk committee can read runs $150,000 to $350,000 and reaches production in 16 to 24 weeks. A full custom platform covering capture, valuation, scheduling, actualisation, settlement and regulatory reporting runs $500,000 to $1,200,000 across 12 to 24 months. Each additional market or commodity adds $40,000 to $120,000.
Trade volume is almost irrelevant to the price, which catches most buyers out. A firm executing thousands of vanilla swaps a month is cheaper to build for than one executing forty tolling and heat rate option deals a year. Count structures traded in the last two years, not tickets.
A generation owner and marketer with assets in three markets, a physical gas book supporting the fleet, and tolling, heat rate option and storage deals currently held as free text totals about $298,000 for the structured layer, near the top of the band because of three markets and three non standard structures. A single market power only firm with one structured product lands nearer $175,000.
Running cost is 18 to 25 percent of build a year, higher than most categories because deal structures evolve continuously and every new structure is a model change. Tariff and market rule changes run $20,000 to $75,000 a year. Hosting for overnight mark and scenario runs, which are bursty and have a hard morning deadline, is $12,000 to $45,000. Analyst and trader training is $6,000 to $18,000, and independent model validation is an annual commitment in both external cost and internal quantitative time. Market data subscriptions are priced by your data vendors rather than by any developer and are typically the largest recurring line in the whole stack, so confirm entitlement for any new use before designing around a feed.
What does the hybrid look like, and when is it the honest answer?
For most firms this is not a compromise, it is the recommendation, and we say so before quoting anything. Keep the packaged system as the book of record for vanilla capture, confirmations and settlement. Build only the layer where your firm is actually different: curve construction with versioned methodology and reproducible historical marks, valuation for the structured deals your business negotiates, credit exposure under your specific agreements, and attribution shaped to how your committee thinks. The layer reads positions from the packaged system and writes valuations back, so the second book disappears without a replacement programme.
Keeping the incumbent as system of record is the single largest saving available in this category. Two more sit beside it. Defer scheduling and actualisation, which are operationally heavy and frequently handled adequately elsewhere in the business. And reuse market data you already license somewhere in the firm rather than adding an entitlement, because that recurring cost is larger than most people expect.
Full replacement becomes defensible in a narrow set of cases: your business is a single unusual asset class no vendor models, you are a small firm whose entire portfolio is structured deals, or a packaged implementation has already failed twice and the requirements turned out to be genuinely non standard rather than badly specified. Those are real situations. They are not most situations.
One rule regardless of route: run at least one full month of parallel marking before anyone relies on the new numbers. Differences will appear, and in our experience most of them turn out to be the old spreadsheet being wrong. That is the point of the exercise, and it needs a month of calendar and a calm room with trading, risk and finance in it.
Which should you choose, by operator size and stage?
Mostly vanilla forwards and swaps, mid market. Buy Molecule. Deploy it, run it, and revisit only if your desk starts structuring contracts the template cannot express.
Large multi commodity trading house. Buy Endur or Allegro for breadth, then consider the structured layer beside it if extension pace becomes the constraint on how fast you can trade something new.
Single market power firm with one structured product. The structured layer at around $175,000. Prove the model on the market carrying most of your risk before extending to a second.
Generator or marketer across several markets with three or more structures. The structured layer at $250,000 to $350,000, keeping the packaged system for capture and settlement with no plan to replace it. This is the outcome we recommend most often for firms in this position.
A firm whose entire portfolio is structured, or one carrying two failed implementations. Full custom across 12 to 24 months, with independent model validation budgeted separately rather than treated as part of delivery.
Whichever route, price each deal structure as its own line in any quote. Tolling, heat rate options and storage carry very different modelling effort, and one line labelled structured products hides which model is being estimated and which one will overrun. Trader availability, not engineering capacity, sets the pace, so book those sessions in advance and treat them as the critical path.
When you are ready to turn this into a specification, Digital Heroes writes a product requirements document before any code exists, so the scope is fixed and priced rather than discovered later at a day rate. You can take that specification to any other firm on your shortlist.

Frequently asked questions
What does it cost to switch ETRM vendors, and does building change that?
Switching a packaged system is dominated by implementation and data migration rather than licence, and enterprise moves routinely run over a year once integrations and history are counted. That is the honest reason most firms stay put longer than they intend to.
Building the valuation and risk layer alongside your incumbent changes the picture in one specific way: once curve construction, structured valuation and attribution live in your own code, the packaged system becomes a capture and settlement engine rather than the centre of gravity, and replacing it later is a smaller decision than it is today.
What if our vendor changes its pricing or bundles more implementation services?
Model total cost of change rather than licence, because in this category the licence is rarely the number that hurts. What to price is how much it costs and how long it takes to add a new deal structure, since extension runs through the vendor's scripting environment and specialist people.
The practical test is to ask your vendor to quote the last structure your desk traded for the first time. The answer tells you more about your five year cost than any renewal schedule will.
How long before the desk stops maintaining its own spreadsheet?
Sixteen to twenty four weeks to production for the structured layer, then one full month of parallel marking before anyone relies on the output. The spreadsheet does not get retired on a launch date, it gets retired when the desk stops finding differences it disagrees with.
Pace is set by trader availability rather than engineering capacity, because every valuation model needs a desk conversation to validate. A model built without the trader who structures those deals will be rebuilt.
Is Molecule enough for a power and gas trading book?
For a straightforward book it is a strong purchase, and many firms should buy it rather than build anything. It deploys quickly, it is cloud native and the interface is well ahead of the enterprise incumbents.
Its opinionated model is both the strength and the limit. Heavily structured portfolios with tolling agreements, storage ratchets or load following obligations push against the model rather than fitting inside it. The usual answer for those firms is Molecule for the book plus a custom layer for the structured deals, not a replacement.
Should we replace our current system or build alongside it?
Build alongside it, for most firms. Trade capture for vanilla instruments, confirmations and basic settlement are commodity capability, and rebuilding them costs a great deal while gaining nothing.
What is worth owning is the part where your firm is genuinely different: curve construction, valuation for negotiated structures, credit exposure under your specific agreements, and attribution shaped to your risk committee. That layer typically costs a fraction of a platform replacement and removes the second book entirely.
Does trading volume affect what this costs?
Almost not at all, which surprises most buyers. Price is driven by the number of distinct deal structures rather than by throughput, so a firm executing thousands of vanilla swaps a month is cheaper to build for than one executing forty tolling and heat rate option deals a year.
Count structures traded in the last two years, including the ones traded once and never documented. Discovery reliably finds deals nobody on the technology side knew existed, and that list is what prices the project.
Do we need independent model validation for a custom valuation layer?
If the output reaches board level risk reporting or supports hedge accounting, yes, and budget it separately rather than folding it into delivery. A development team that welcomes independent validation is telling you something useful about its confidence in the models.
Validation also produces the methodology and assumptions documentation that saves considerable time during audit and diligence. Agree up front who owns that documentation, because a build that produces correct numbers without it simply creates a second piece of work at review time.
What does it cost to add another market or commodity later?
Between $40,000 and $120,000, covering new market results, new scheduling mechanics and new settlement data. Adding physical gas to a power book sits at the upper end, because transport, storage and imbalance are a different family of models rather than an extension of the existing ones.
Price expansion into the asset case rather than treating it as configuration. Firms that assume a second market is a settings change are the ones whose second market arrives two quarters late.
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.
What should I have ready before I contact a development agency?
Three things, none of them technical: a one-page description of the problem in your own words, a list of the tools and spreadsheets the new system must replace or connect to, and a must-have versus nice-to-have split of features. Add a budget range, even a wide one, because it changes the conversation from fantasy to engineering. You do not need a formal specification; producing that is what a discovery phase is for.
How long does it take from first call to software my team can actually use?
Plan for four to six months: two to three weeks of discovery, two to four weeks of design, then a 10 to 16 week build with testing. In Digital Heroes delivery experience the schedule killer is not engineering speed but decision lag; a client who takes two weeks to approve wireframes adds two weeks to launch. Book a weekly 30-minute decision slot before kickoff and most of that risk disappears.
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.
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.
How do we get years of data out of our old system and into the new one?
Treat migration as a planned sub-project: a field-mapping document, at least one dry run on a copy of your data, then a cutover with the old system kept read-only for 30 days as a safety net. On Digital Heroes projects it consumes 10 to 15% of the budget when the old system has an export, and more when data must be pulled out screen by screen. Ask any vendor to walk you through their last migration before you sign.
What should I prepare before contacting a software development agency?
A one-page brief beats a 40-page requirements document: the business problem in plain words, who will use the system, the 5 to 10 workflows it must handle, the tools it must connect to, and your budget range and deadline driver. You do not need wireframes, a specification, or technical vocabulary; producing those is the agency's job during discovery. Stating a budget range up front is the single best move, because it gets you honest scoping instead of a quote engineered to win the meeting.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
Who can build a custom software system?
Digital Heroes builds custom software 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 software 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.
