$85,000 to $450,000, and the single decision that moves the number most is whether suppliers and their workers touch the system directly. Keep assessment internal, with your category managers and compliance team collecting evidence against a site hierarchy you control, and a first release sits at the bottom of that range. Open a supplier portal in the languages your factories actually operate in, plus a worker facing grievance channel, and you add localisation, confidentiality controls, retention rules and an inbound support load that together account for most of the gap between a $140,000 build and a $400,000 one.
The bands a due diligence build falls into
Three bands, and most buyers can place themselves within two minutes. Below roughly 200 direct suppliers in lower risk categories, with no statutory duty yet, there is no build. You are in subscription territory and the rest of this page is background reading.
The first band, $85,000 to $170,000 over 12 to 18 weeks, buys the system of record. That means supplier group, legal entity, site and commodity modelled as separate objects and bound to your purchase order and receipt history, so exposure is calculated rather than asserted. It means your own risk scoring model with named factors, weights, thresholds and a version history. It means assessment intake where evidence is a first class object with a validity period, a source and an immutable copy, not a tick in a questionnaire. And it means corrective actions with owners on both sides, escalation timers and a closure requirement that demands proof. Nothing in that release is supplier facing.
The second band, $200,000 to $450,000 phased over 7 to 12 months, adds everything that touches the outside world: a multi language supplier portal, grievance channel intake with anonymity and case management, adverse media and sanctions screening, beyond tier one mapping built from the signals you can actually obtain, and regulator ready reporting packs assembled from the operational record.
Both figures are Digital Heroes delivery experience on enterprise compliance work, and both assume you keep EcoVadis, Sedex, IntegrityNext or Prewave as data sources rather than replacing them.
What drives a due diligence build up
Languages first. A supplier portal that Chinese, Turkish, Vietnamese and Portuguese speaking factory staff can genuinely use is a localisation programme, not a translation file. Right to left support, non Latin name handling in your matching logic, translated notification templates and a support process in each language are separate work items. Four working languages is roughly the point where this stops being a line item and becomes a workstream.
Grievance intake is second, and it is the feature we most often see underestimated. A worker facing channel that meets confidentiality expectations raises hosting location, access control, retention limits, retaliation protection and an intake path that does not require the complainant to own a corporate email address. Treat it as its own design conversation with legal.
Third is the state of your purchasing estate. Large groups routinely run three or four purchasing systems after acquisitions, and every one of them has to be reconciled to the same supplier and site model before your exposure figures mean anything. Each additional source system is real integration work with its own reconciliation report.
Fourth is jurisdiction count. The German supply chain act, the EU corporate sustainability due diligence directive as it lands in member state law, and import controls that shift the burden of proof onto the importer each imply a different reporting artefact. Two duties is not twice one duty, but it is not one either.
What keeps the number down
Scope by your own risk analysis. Cover the commodity categories and countries your methodology already flags as elevated, and leave the rest on the subscription platform for year one. Covering every supplier in the first release is an expensive way to prove that most of your suppliers are boring.
Build internal first. Every hour spent on a supplier facing portal is an hour not spent on the hierarchy, the risk model and the evidence store, which are the pieces that determine whether the system can answer a question under pressure. Category managers can collect evidence by email for a year while you prove the record layer works.
Keep the subscriptions. Reproducing EcoVadis scorecards or Sedex site audit data is not a saving, it is a second product. Consume them as inputs, accept their refresh cycles, and spend the budget on the layer none of them can supply.
Use document extraction rather than headcount. Supplier evidence arrives as PDFs and photographs in dozens of layouts and languages. A model that pulls issue date, expiry date, scope and issuing body, then flags mismatches for a human, is a two to three week build that removes a compliance analyst's worth of reading. That is the one place in this category where machine assistance clearly earns its cost.
A worked example that adds up
A European manufacturing group with 1,400 direct suppliers across 3,100 sites, a statutory duty under the German act, two SAP instances and one legacy purchasing system inherited from an acquisition. They hold EcoVadis and intend to keep it. First release, internal users only.
- Supplier group, entity, site and commodity model bound to purchase order and receipt history: $28,000
- Risk scoring engine with named factors, weights, effective dated versions and a derivation view on every score: $22,000
- Assessment intake plus the evidence store with validity periods, immutable copies and automatic status change on expiry: $34,000
- Corrective action workflow with dual ownership, escalation timers and proof of closure: $18,000
- Purchasing integration across three source systems with a reconciliation report per system: $24,000
- Reporting pack generator with click through from every figure to its underlying records: $16,000
Total $142,000, delivered in 16 weeks. That sits mid band, and the reason it is not $95,000 is the third purchasing system and the fact that evidence expiry had to drive status automatically rather than appear on a report. Phase two, adding the supplier portal in four languages, grievance intake and screening, was quoted separately at $185,000 across the following seven months.
How the spend phases
Roughly a fifth of the first release goes before any screen is built, and it is not discovery theatre. It is agreeing the risk methodology: which factors, which weights, which thresholds trigger which action, and who signs that off. That conversation needs sustainability, legal, procurement and often the audit committee in one room, and companies arriving with a written methodology move noticeably faster than those expecting the software to supply one.
The middle sixty percent is build, and it front loads the hierarchy and the purchasing binding, because everything downstream inherits those. Expect the first uncomfortable finding in week four, when the reconciliation report shows that a meaningful share of your spend cannot be attributed to a specific site.
The last fifth is parallel running. Keep producing the current spreadsheet alongside the system for one assessment cycle and compare. The differences are almost always the system being right and the spreadsheet carrying an assumption nobody had written down.
Phase two spend follows regulatory deadlines rather than engineering convenience, and that is correct. If a reporting duty lands in a given quarter, the reporting pack ships before the portal.
The ongoing costs nobody quotes
Hosting and infrastructure for a system of this shape runs a few hundred to around $2,000 a month depending on document volume and whether grievance data forces a specific residency. Document storage grows and never shrinks, because retention obligations run for years.
Document extraction has a per page inference cost. At tens of thousands of supplier documents a year it is a modest but real line, and it scales with your supplier base rather than your headcount.
Your subscriptions continue. EcoVadis, Sedex or Prewave do not get cheaper because you built a record layer, and you should not want them to. Budget them as data, not as software you are replacing.
Then there is change. Regulatory scope moves, member state implementations differ, your board adjusts risk appetite, and a new commodity enters the flagged list. We plan on 15 to 20 percent of build cost a year for maintenance and change in this category, which covers hosting, monitoring, regulatory updates and a steady flow of small workflow changes. A system with a grievance channel also needs periodic penetration testing, which sits outside that figure.
Comparing a build against your current renewal
Do the arithmetic honestly and include the labour. A typical group at this size is paying for one broad assessment subscription, one screening or adverse signal tool, a survey platform, and then absorbing the annual report as internal effort plus a consultancy engagement. The subscriptions are visible in the budget. The three months of compliance and sustainability time that goes into assembling the report by hand each year is not, and neither is the week that disappears whenever a customer sends a supply chain questionnaire.
The build does not remove the subscription line. It removes the assembly. If your annual report currently requires a named person reading across three systems for a quarter, that is the number to compare against amortised build cost, and it is usually the number that settles the decision.
The other figure worth pricing is speed of answer. When a campaigning organisation names one of your supplier facilities, the question is whether you buy from it and how much. Today that takes days. That difference is not a software feature, it is your legal exposure.
When buying beats building
Buy if you have a few hundred direct suppliers, mostly in lower risk categories and jurisdictions, and your obligation today is a customer questionnaire rather than a statute. An EcoVadis subscription plus a disciplined internal process is proportionate, gives you a comparable scorecard, and puts you in a format your suppliers already recognise. Building at that stage is an expensive way to feel serious.
Buy if your risk genuinely does sit at the legal entity level, because your suppliers are single site and your purchasing is centralised. The whole cost of a custom build is in modelling complexity you may not have.
Buy if nobody internally will own the system. A due diligence platform encodes your risk methodology, and a methodology without an owner drifts within one cycle.
Build when your risk sits at site level and your vendor master cannot say which site fulfils an order, when you carry a statutory duty with enforcement exposure, when you operate in commodities where an import can be detained and the burden of proof is yours, or when you are already paying for two or three subscription platforms and still assembling the annual report by hand. That last one is the clearest signal in the category.
If you want a second opinion before signing anything, Digital Heroes has delivered more than 2,000 projects with a named team you can speak to before you sign, rather than a bench you meet in month two. You can take that specification to any other firm on your shortlist.

Frequently asked questions
What is the total cost of custom supply chain due diligence software?
A first release covering the supplier and site hierarchy bound to purchasing data, a versioned risk model, assessment and evidence management, and corrective action workflow runs $85,000 to $170,000 over 12 to 18 weeks in Digital Heroes delivery experience. A full platform adding a multi language supplier portal, grievance intake, screening, beyond tier one mapping and regulator reporting packs runs $200,000 to $450,000 across 7 to 12 months.
The realistic mid point for a group with a few thousand supplier sites and more than one purchasing system is around $140,000 for the internal release, with the supplier facing phase quoted separately.
What does it cost to run each year after launch?
Plan on 15 to 20 percent of build cost annually. For a $142,000 first release that is roughly $21,000 to $28,000 covering hosting, monitoring, regulatory changes, integration maintenance as your purchasing estate shifts, and a steady stream of small workflow adjustments.
On top of that sit two costs buyers forget: your existing subscriptions continue, because you are keeping them as data sources rather than replacing them, and document extraction carries a per page inference cost that scales with supplier volume. If you run a grievance channel, add periodic penetration testing.
How long does it take to build?
Twelve to eighteen weeks for a usable first release. The pacing item is rarely engineering. It is agreeing your own risk methodology, meaning which factors, which weights and which thresholds trigger which action, which needs sustainability, legal, procurement and often the audit committee in agreement.
Companies arriving with a written methodology routinely ship at the twelve week end. Companies expecting the software to supply the methodology add four to six weeks before a line of code helps them.
Is an EcoVadis subscription cheaper than building?
Substantially, and for many companies it is the right answer. EcoVadis gives you a comparable supplier scorecard in a format your suppliers already understand, which is genuine value at a fraction of a build.
What it cannot hold is your risk thresholds, your escalation policy, your evidence with validity periods and your purchasing exposure by site, because those are specific to your company. Most mature programmes keep the subscription and build the record layer around it, so the comparison is not build against subscription, it is subscription alone against subscription plus a record layer.
Why does a multi language supplier portal cost so much?
Because it is a localisation programme rather than a translation file. Non Latin name handling changes your supplier matching logic, right to left layouts change the interface, every notification template multiplies, and each language implies a support path for suppliers who cannot complete a step.
In our experience four working languages is where this stops being a task inside the build and becomes a workstream of its own, and it is the largest single reason a due diligence platform moves from the lower band to the upper one.
Can we phase the build to spread the cost?
Yes, and the correct split is internal before external. The hierarchy, risk model, evidence store and corrective actions carry almost all the compliance value and none of the localisation cost, so they ship first at $85,000 to $170,000.
The supplier portal, grievance channel, screening and beyond tier one work then follow as a separately funded phase, sequenced against your actual reporting deadlines rather than engineering convenience. If a statutory report is due in a given quarter, the reporting pack ships ahead of the portal.
What makes these projects go over budget?
Three things, consistently. Purchasing fragmentation, where a group discovers mid build that it has four systems placing orders and no consistent supplier identifier across them. Grievance channel scope, which turns into a confidentiality and retention design exercise once legal engages properly. And language count, which is often agreed loosely at kickoff and firmed up late.
The way to control all three is to settle them in writing before the estimate: how many source systems, whether workers file grievances directly, and exactly which languages.
Do we need to rebuild anything when the regulation changes?
Not if the risk model is versioned with effective dates from the start. A scope change adds a new model version, historical decisions still render under the model in force when they were made, and no record is silently recalculated.
What does cost money is a new reporting artefact for a new jurisdiction, because each duty implies its own format and validation. Budget that as a change rather than a rebuild, and it usually sits inside the annual maintenance allowance unless a whole new regime applies to you.
How does the cost compare with what we already spend on the annual report?
Compare the amortised build against the labour, not against the software line. A group at this scale typically absorbs a quarter of compliance and sustainability time assembling the statutory report by hand across three systems, plus consultancy support, plus the week that disappears every time a customer sends a supply chain questionnaire.
Those hours never appear in a software budget, which is why the build looks expensive on a spreadsheet that only counts licences. Add them in and the payback period usually falls inside two reporting cycles.
How big a development team does a supply chain software project need?
A typical build runs with 4 to 6 people: a project lead or analyst, two or three developers, a QA engineer, and a part-time designer. Digital Heroes staffs most supply chain MVPs this way for 10 to 14 weeks, then drops to 1 or 2 people for maintenance after launch. Bigger is not better here; past 7 or 8 people on a single-product build, coordination overhead usually cancels the added speed.
Does it matter which tech stack the agency wants to use?
Yes, but not in the way most buyers expect: the goal is boring, popular technology such as React, Node.js or Python, and PostgreSQL, because any future team can maintain it and hiring a replacement developer takes days, not months. The red flag is an agency-proprietary framework or an unusual language, which welds you to that one vendor no matter what your contract says about code ownership. A useful test: could you find three freelancers fluent in this stack within a week? If not, push back.
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.
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 companies make on supply chain software projects?
The top three: replacing every system at once instead of one workflow at a time, skipping data cleanup so the new system inherits years of bad SKUs and phantom stock, and designing screens without the warehouse staff who will use them daily. A fourth is underscoping integrations and discovering mid-project that the ERP connection is half the work. Digital Heroes sees more supply chain projects fail from scope and data problems than from any technical cause.
We run everything on spreadsheets and Airtable. How do we know it's time for custom software?
The reliable signals are re-typing the same data into multiple tools, one employee acting as human middleware between systems, and errors appearing in handoffs between teams. Hard limits force the issue too: Airtable's Team plan caps at 50,000 records per base, and Business costs $45 per seat per month, so a 20-person team pays about $10,800 a year for a tool it has already outgrown. When workarounds consume more hours than the tools save, the spreadsheet era is over.
Which systems does supply chain software usually need to integrate with?
The standard set is your accounting or ERP system (QuickBooks, NetSuite, SAP), your sales channels (Shopify, Amazon, or a B2B portal), carriers and 3PLs for rates and tracking (UPS, FedEx, or an aggregator like EasyPost), and warehouse hardware such as barcode scanners and label printers. EDI connections to large retail customers are their own workstream. In Digital Heroes scoping, integration work is commonly 30 to 50 percent of total project effort, so listing every connected system upfront is the single best way to get an accurate quote.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
Who can build a custom supply chain software system?
Digital Heroes builds custom supply chain 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 supply chain 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.
