Pick the firm that asks how your risk scoring will be versioned before it asks about screens. A model you cannot reproduce as it stood two years ago is not evidence, it is a number. Expect $85,000 to $170,000 for a first release in 12 to 18 weeks, and $200,000 to $450,000 for a full platform. Under 200 direct suppliers with no statutory duty, subscribe instead.
Commissioning due diligence software is like building the filing system for a court case nobody has served on you yet. Everything you capture today is only worth what it proves later, in a room where the questions are asked by an auditor, a regulator or a journalist with a named facility and a date. The work feels administrative right up to the moment it is the only thing standing between you and an answer you cannot give.
What makes this awkward to buy is that the deliverable is a defence, not a dashboard. Agencies will show you supplier surveys and heat maps because those demo well. The obligations that actually bind you are about prioritising by risk, taking action proportionate to it, and holding evidence that the action happened. Every one of those is a data modelling decision made in week two of the project by a developer who may never have read a due diligence statute.
What a due diligence development company actually does
The questionnaire builder is the cheap part. What you are buying is a chain of defensible records.
A firm that has built here starts with hierarchy. Group, legal entity, site and commodity are separate objects, bound to your own purchase order and receipt history, because a vendor record is a payment construct with bank details and risk lives at the facility. Until that binding exists you cannot answer the two questions a crisis asks: do we buy from this site, and how much.
Then the risk model, expressed as named factors with weights, thresholds and a version history rather than a supplier's proprietary blend. Country and sector indices feed in as inputs alongside your own signals: audit findings, grievance reports, sudden subcontracting, single site dependency. Every score renders as a derivation showing what contributed. Then evidence, which is where most builds fall short. A document is not a file. It has a validity period, a scope, an issuing body and a source, and when it expires the site status changes automatically instead of quietly aging. Corrective actions carry owners on both sides, escalation timers and a closure requirement that demands proof rather than a confirmation email.
What it really costs in 2026
These bands assume you keep an existing subscription such as EcoVadis, IntegrityNext or Prewave as a data source and build the record layer around it.
| Scope | Cost | Timeline |
|---|---|---|
| Diligence core: group and site hierarchy bound to purchasing data, versioned risk model, assessment and evidence management, corrective actions | $85,000 to $170,000 | 12 to 18 weeks |
| Full platform: beyond tier one mapping, grievance intake with case management, adverse media and sanctions screening, multi language portal, regulator reporting packs | $200,000 to $450,000 | 7 to 12 months |
| Additional purchasing system integration in a fragmented estate | $20,000 to $55,000 each | 3 to 6 weeks each |
| Support, methodology changes and annual reporting cycles | 15 to 20 percent of build cost a year | Retainer |
Two costs are consistently missing. The first is agreeing your own risk methodology. Which factors, which weights, which thresholds trigger which action is a policy decision needing sustainability, legal, procurement and often the audit committee in one room, and it is the dominant schedule risk on every project of this type. Companies arriving with a written methodology move considerably faster than those expecting the software to supply one.
The second is the reporting calendar. Statutory due diligence regimes attach a report to your financial year, with a filing window that does not move because your build slipped. If your obligation falls in the first year after go live, the reporting pack is not a phase two feature, it is the deadline the whole plan should be drawn backwards from. Firms quoting a build sequence without asking your financial year end have not thought about this.
Signals of a strong partner
- They ask how you know which site fulfils a purchase order. Within about five minutes. That question separates people who have built this from people who have built a survey tool.
- Risk scoring is versioned with effective dates. A decision made two years ago renders under the model in force then. Anyone treating the score as a mutable column has not built for regulated evidence.
- Evidence has a validity period and an immutable copy. Superseded documents are kept, not overwritten, and expiry changes a status rather than triggering a reminder somebody ignores.
- They are honest about upstream visibility. Cascading questionnaires lose response rate at every level. A firm that says so and proposes combining partial signals with a confidence level is telling you the truth.
- Document extraction is offered narrowly. Reading issue dates, expiry, scope and issuing body from certificates in many languages, then flagging mismatches for a human. That is the one place machine learning earns its keep here.
- They ask about grievance channel obligations early. Anonymity, language access, restricted reading, retention limits and retaliation protection are design constraints, not a form on the portal.
- Repository, cloud accounts and exit rights settled before kickoff. Your diligence record is legal evidence with a multi year retention expectation and must never sit somewhere you cannot move it from.
Red flags
- They offer a risk score out of the box. A generic blend of country and sector indices cannot know your commercial influence, your contract terms or your board's risk appetite, and pointing at it is a weak answer to a regulator.
- Assessment and evidence are the same object. A questionnaire answered yes is not proof. If the model has no separate evidence entity with scope and validity, the system produces confidence rather than a defence.
- History is recalculated when the methodology changes. Silent recalculation destroys exactly what you built the system to hold. Ask this question before you discuss screens.
- The supplier portal ships in one language with translation files planned later. A portal Turkish, Vietnamese and Portuguese speaking staff cannot use produces incomplete data, which is worse than none because it looks complete.
- No plan for keeping subscription data in sync. You will keep an external assessment provider as an input, their refresh cycles are theirs, and a firm without an answer will leave you with two versions of the truth.
Questions to ask on the first call
- Draw group, legal entity, site and commodity, then show where our purchase orders attach.
- How is the risk model versioned, and how would you reproduce a decision made under the previous version?
- What happens in the system on the day a certificate expires?
- How do you handle a supplier whose declared upstream chain cannot be verified?
- Which of our existing subscriptions would you ingest, how often, and who resolves a conflict between their data and ours?
- What does the annual reporting pack look like, and can every figure in it be clicked through to source records?
- How would you design grievance intake so that only named people can read a report?
- What do you need from our purchasing systems, and what happens if we have four of them?
- Where does the data live, and what exactly can we take with us if we change firms?
A simple way to decide
Do not decide from a proposal. Buy a paid discovery phase from your two strongest candidates and insist it produces a document. Three to four weeks at a defined fee should leave you owning a written specification: the hierarchy and purchasing linkage design, your risk methodology expressed as versioned logic with worked examples against real suppliers, the evidence object with validity and access rules, the reporting pack mapped to your filing calendar, and a phased price. It is yours to take to any other firm, or to shelve.
A firm that cannot write that in a month will not deliver in a year. Digital Heroes works product requirements document first as standard, runs a team of over fifty, and contracts through an India LLP, a US LLC or a UK LTD so the intellectual property assigns under your own law. We are the wrong choice if you have a few hundred direct suppliers in lower risk categories and jurisdictions and your obligation today is a customer questionnaire rather than a statute. An EcoVadis or Sedex subscription plus a disciplined process is proportionate, and a build would be an expensive way to feel serious.

Frequently asked questions
How long does it take to build a supply chain due diligence platform?
A first release ships in roughly 12 to 18 weeks. The dominant schedule risk is not engineering but agreeing your own risk methodology, since deciding which factors, weights and thresholds trigger which action needs sustainability, legal and procurement in the same room. Companies arriving with a written methodology move much faster. If a statutory report falls in your first year, plan backwards from that filing date.
Who owns the code and the diligence records if an agency builds this?
You should own the repository, the cloud infrastructure accounts and the unrestricted right to hire another firm, agreed in writing before kickoff. Your due diligence record is legal evidence with a multi year retention expectation and may be examined long after the project team has moved on. It must never be locked inside infrastructure you cannot move or a contract you cannot exit.
Can we use EcoVadis or Prewave alongside a custom system?
Yes, and most mature programmes end up hybrid. Subscriptions give you comparable supplier scores and adverse signal detection across a base that already knows the format, which is genuinely useful. What they cannot hold is your risk thresholds, your escalation policy, your evidence with validity periods and your exposure by site. Ingest them as inputs and keep the system of record yours.
What is the difference between a supplier assessment and due diligence evidence?
An assessment is a claim: a questionnaire answered, a score assigned, a certificate uploaded. Evidence is the underlying artefact with a scope, a validity period, an issuing body and a source, capable of supporting the claim when someone tests it. Systems that treat the two as one object produce a tidy record that collapses the first time an auditor asks how a particular answer was verified.
Should we extend our existing compliance platform instead of building?
Ask the incumbent two questions: can it bind assessments to specific sites reconciled against your purchase orders, and can it reproduce a risk decision under the methodology in force at the time. If both answers involve a professional services engagement, you are buying a custom build with a licence fee attached. Extending is right when the gap is a report, not the data model.
What happens to past decisions if we change our risk methodology?
Nothing should be overwritten. The model is versioned with effective dates, so a decision made under an earlier version still renders under that version while new decisions use the current one. Regulators and auditors look backwards, and a system that silently recalculates history destroys the evidence you built it to produce. Ask any prospective developer how they version scoring logic before discussing screens.
Can software really give visibility beyond our direct suppliers?
Not outright, and any vendor promising full multi tier visibility from cascading surveys is selling comfort. Response rates fall at every level and the answers are largely unverifiable. What works is combining partial signals: declared chains where suppliers disclose, chain of custody documents where a scheme exists, trade data where you have access, and enforcement signals mapped to named facilities, presented with a confidence level.
How much does a multi language supplier portal add to the cost?
Expect a meaningful addition rather than a translation file, often 15 to 25 percent of the portal scope. Language affects field labels, validation messages, document requests, help content and support coverage, and getting it wrong produces incomplete responses that look complete. Prioritise the languages your highest risk supplier populations actually work in rather than covering every market at once.
Where does artificial intelligence genuinely help in due diligence work?
Mainly in document extraction. Supplier evidence arrives as PDFs and photographs in many languages and layouts, and a model can pull issue dates, expiry dates, scope and issuing body, then flag documents that contradict what the supplier claimed. That processes material nobody currently reads. Adverse media screening also benefits from entity matching, though every hit needs human review before it changes a supplier status.
Do we need this with 200 suppliers and no statutory obligation?
Probably not, and we would say so before quoting. With a few hundred direct suppliers in lower risk categories and jurisdictions, a subscription plus a disciplined internal process is proportionate. The case for building starts with a statutory duty carrying enforcement exposure, risk that sits at site level your vendor master cannot resolve, or two subscriptions already in place while the annual report is still assembled by hand.
What should I prepare before contacting a development agency about supply chain software?
Bring a written list of your workflows from purchase order to delivery, the systems each step touches, and the 3 to 5 pain points costing you the most hours or errors. Export a sample of your real data, SKUs, orders, and locations, because data shape drives half the design decisions. You do not need a formal spec; Digital Heroes scopes most supply chain projects from a two-page problem description plus screen-share walkthroughs of the current process.
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.
What does it cost to maintain custom supply chain software each year?
Budget 15 to 20 percent of the original build cost per year, so roughly $9,000 to $12,000 annually on a $60,000 system, covering hosting management, dependency updates, bug fixes, and small enhancements. Across its maintenance contracts, Digital Heroes sees supply chain systems need more upkeep than typical web apps because carrier APIs, EDI specs, and ERP versions keep changing underneath them. Hosting itself is usually minor, often $100 to $500 per month for a mid-size operation.
What tech stack is best for custom supply chain software?
Boring and mainstream wins: a typed backend such as Node with TypeScript, Python, or C#, PostgreSQL for transactional inventory data, a React web frontend, and hosting on AWS, Azure, or GCP. Real-time needs like scanner feeds or live shipment tracking add a message queue such as Redis or RabbitMQ. Be wary of any agency pitching an exotic stack; in Digital Heroes handover work, systems built on niche frameworks are consistently the hardest and most expensive for a new team to take over.
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.
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.
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.
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.
