Ask how a worker identity survives moving between two suppliers. If the person is attached to the requisition, tenure tracking will not work in exactly the cases where it matters. A first release covering requisition to invoice with enforced rate cards runs $80,000 to $170,000 in 14 to 20 weeks. Under a hundred workers, buy a mid-market system.
The quarterly programme review is next week. There are 1,400 contingent workers across nineteen suppliers, a negotiated rate card with 63 job titles, and a spend number your finance business partner does not trust. An analyst samples forty invoices and finds eleven that do not match. A senior developer billed at the architect rate because the submission said architect and nobody read the title. A markup at 42 percent where the agreement says 34. Three workers still invoiced two weeks after their assignment ended because nobody closed the requisition. None of it is fraud. It is a system with no enforcement point.
Buying a developer for this is difficult because your requirements are contradictory and you do not know it yet. Most organisations discover during encoding that their tenure policy, their approval hierarchy and their boundary between staff augmentation and outcome-based work disagree with each other in writing. Vendors quote against the policy you describe. The build costs what the policy actually is once someone has forced it to be consistent, which is a discovery finding, not a change of scope.
What a services procurement software company actually does
The requisition to invoice flow is a commodity and you should not pay much for it. Three other things are where the engagement lives.
The rate card as a validation rule rather than a reference document, so a submission exceeding the band for its title, location and skill level is blocked or requires a named exception with a reason, every exception is reported, and markup is calculated and shown to the hiring manager rather than buried. Supplier scorecards then carry compliance rate alongside submission quality and fill time, which changes behaviour faster than any contract clause. Statement of work engagements modelled properly, with milestones that carry acceptance criteria, a named acceptor and an invoice release gated on acceptance rather than elapsed time, and with the people working under that statement of work registered as identities with start and end dates even though they are not billed hourly. And identity lifecycle driven by the assignment: approval triggers provisioning with the specific requirements for that role and site, assignment end triggers deprovisioning with confirmation required from each system owner, and expiring safety certifications alert before the worker turns up at a site they can no longer legally enter.
What it really costs in 2026
| Scope | Cost | Timeline |
|---|---|---|
| Requisition through submission with enforced rate cards, assignment records, timesheet capture and approval, self-billed invoicing with cost allocation | $80,000 to $170,000 | 14 to 20 weeks |
| Full platform adding statement of work milestone control, onboarding and access provisioning, tenure and policy checks, supplier scorecards and analytics | $200,000 to $500,000 | 8 to 14 months, phased |
| Run, new countries and supplier onboarding | 15 to 20 percent of build per year | Retainer |
Two line items go missing from almost every quote.
Supplier onboarding and training. Nineteen suppliers each need connecting, training and chasing, and some will quietly resist a system that makes their markup visible to your hiring managers for the first time. That resistance is the single most common reason a programme stalls after go-live: adoption fails, suppliers keep emailing spreadsheets, and you have paid for an enforcement point that nobody submits through. Price it per supplier, name an owner on your side, and put contractual teeth behind it before the build starts.
Your own policy reconciliation. Someone has to sit with legal, HR (Human Resources) and procurement and resolve what your tenure limit actually is, when a cooling off period applies, who may approve an exception, and where the line sits between staff augmentation and outcome-based work. That work is unbillable and blocking. Nothing about worker classification here is legal advice: your counsel defines the test and the system's job is to capture the evidence, who directs the work, who supplies the tools, how the engagement is priced and how long it has run.
Signals of a partner who has run a programme
- They separate worker identity from requisition in the first conversation, so tenure is calculated on the human across suppliers and name spellings.
- They propose self-billing. Generating the invoice from approved time and accepted milestones removes the dispute entirely. An invoice inbox does not.
- They ask about accruals for unapproved time, which is a small feature your controller will care about more than anything else in the build.
- They name the identity and access systems they have provisioned against, including badge and physical access, rather than describing joiner mover leaver as a capability.
- They ask where cost centre and project coding is set, because allocation at approval is what makes the accounting entry correct before it reaches your enterprise system.
- They ask how much of your spend is statement of work, and are not surprised when the answer is most of it and none of it is visible.
- They scope release one to one country and your five largest suppliers, staff augmentation only.
Red flags
- A statement of work is modelled as a container for hours. That is the wrong shape for outcome-based work, where deliverable acceptance and milestone gating are the controls that matter.
- They plan to build an invoice inbox. It tells you they have not understood where disputes come from and you will still be reconciling four thousand lines by hand.
- Deprovisioning is a notification. If assignment end does not trigger removal with confirmation from each system owner, badges and network accounts outlive assignments and internal audit will find them before you do.
- The rate card is a lookup screen. If it does not validate at submission, it stays the document nobody reads and the leakage continues at exactly the same rate.
- They offer an opinion on worker classification. That belongs with your counsel. A vendor volunteering a legal conclusion is a vendor who will hand you their answer in writing and then leave.
Questions to ask on the first call
- A contractor leaves supplier A, joins supplier B four months later under a different spelling of her name, and is submitted for a role at the same site. What does your model do?
- Show me a submission at 42 percent markup where the agreement says 34. Who is blocked, who can approve the exception, and where does that appear afterwards?
- How is the invoice produced? Walk me through self-billing from approved time and accepted milestones, and what the fallback is when a supplier insists on invoicing us.
- A statement of work milestone is invoiced before anyone formally accepted the deliverable. What stops the payment?
- Eight consultancy staff have badges and system access under a fixed-fee statement of work. How does your system know they exist, and what happens on the end date?
- Which identity providers, badge systems and background screening providers have you provisioned against, by name?
- Our tenure policy and our approval hierarchy contradict each other. Who on your side surfaces that, and when in the plan?
- How are accruals for unapproved time calculated at month end, and what reaches our enterprise system as the accounting entry?
- Who owns the code, the cloud accounts, the rate cards and the supplier performance history from the first commit?
A simple way to decide
Buy a paid discovery phase before you buy a platform or a build. Four to six weeks, ending with a written specification you own: the worker identity model, the rate card structure with its validation rules and exception path, the statement of work milestone and acceptance design, the identity provisioning and deprovisioning map by system, the tenure and policy checks with the evidence each one captures, and a phased plan starting in one country with your five largest suppliers. Take it to SAP Fieldglass, Beeline and two development firms. You will finally see the honest comparison, which is usually that the licence is affordable and the configuration is the project.
If you run fewer than about a hundred contingent workers with a handful of suppliers in one country, Digital Heroes is the wrong call. A mid-market vendor management system or a module in your existing procurement suite will do the job for a fraction of a build. Where we fit is the programme whose statement of work spend nobody can see, PRD-first, contracting through an India LLP, a US LLC or a UK LTD so the assignment sits under your own law.

Frequently asked questions
How much does a custom services procurement or VMS build cost?
A focused first release covering requisition through submission with enforced rate cards, assignment records, timesheet capture and approval, and self-billed invoicing with cost allocation runs $80,000 to $170,000 over 14 to 20 weeks. A full platform adding statement of work milestone control, onboarding and access provisioning, tenure and policy checks and supplier scorecards runs $200,000 to $500,000 phased across 8 to 14 months.
When should we buy Fieldglass or Beeline instead of building?
Buy when you run fewer than roughly a hundred contingent workers with a handful of suppliers in one country, or when you need broad global coverage quickly, have a managed service provider partner to run the programme, and your processes are close enough to standard that you can adopt rather than adapt. Building makes sense when statement of work spend is large and invisible, or configuration quotes keep coming back high.
What is the most common technical mistake in a VMS build?
Attaching the worker to the requisition rather than giving them a persistent identity across suppliers and assignments. The moment a contractor returns through a different supplier under a different spelling of their name, tenure and rehire policy checks stop working, which is precisely the case those policies exist for. Ask a vendor to walk that scenario through before you discuss anything else.
Why does supplier onboarding get underestimated?
Because it is people work, not engineering. Every supplier needs connecting, training and chasing, and some will quietly resist a system that makes their markup visible to hiring managers for the first time. Failed adoption after go-live, with suppliers still emailing spreadsheets, is the most common way these programmes stall. Price onboarding per supplier, name an owner internally, and put contractual teeth behind it before the build starts.
Should the software make worker classification decisions?
No. Your counsel defines the test and the system captures the evidence: who directs the work, who supplies the tools, how the engagement is priced and how long it has run. Rules differ by country and by state and continue to change. What a build should do is make the fact pattern visible, so a statement of work engagement being tracked by hours and directed daily by your manager shows up before someone else notices it.
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.
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.
What happens to my software if the agency shuts down or we stop working together?
Nothing dramatic, if the engagement was set up correctly: the code sits in your repository, hosting runs on your cloud account, and a handover document explains how to deploy and operate the system. Any competent replacement team can then take over in days rather than months. If the agency controls the repo, the servers, or the domain, fix that now, because renegotiating access during a dispute is the most expensive place to discover the problem.
How long does it take to build a custom web or mobile app from scratch?
Plan on 8 to 16 weeks for a focused first version and 4 to 9 months for a larger platform, which is the typical spread across Digital Heroes builds. The first 2 to 3 weeks go to discovery and design before any production code ships. The two things that stretch timelines most are integrations with legacy systems and slow feedback from your side, not developer speed.
How do I vet a software development agency before signing a contract?
Ask to speak with two past clients whose projects resemble yours in size and industry, and ask exactly who will write your code, since some agencies sell senior faces and deliver junior or subcontracted hands. Demand a written specification with acceptance criteria before any fixed price, and check that their portfolio links to products that are actually live. An instant quote given without questions about your workflows is the clearest warning sign there is.
Who owns the code when an agency builds my software?
You should, completely, through a written intellectual property assignment that transfers everything on final payment; without that clause, copyright stays with whoever wrote the code by default. Insist that the repository lives in your own GitHub organization from day one and that hosting, domains, and third-party accounts are registered to you. Also check for licenses to the agency's proprietary frameworks buried in the contract, because those can make switching vendors practically impossible even when you own your own code.
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 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.
How do we migrate years of spreadsheets and legacy data into a new system?
Migration runs as its own workstream: extract and profile the data, clean duplicates and dead SKUs, map fields to the new schema, then do trial loads and a final cutover during a weekend or slow period. Expect 2 to 6 weeks depending on how many sources you have and how dirty they are. Digital Heroes runs old and new systems in parallel for 2 to 4 weeks on most supply chain cutovers so inventory counts and open orders can be reconciled before the legacy system is retired.
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.
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?

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.
