Make them draw the material model before you sign anything: heat, cast sequence, slab, coil, child coil, cut length, each with parents, children and transformation events. A firm that draws a batch and a quantity has built warehouse software. A first release runs $120,000 to $250,000 over 16 to 24 weeks. Buy discovery before you buy code.
A coil comes off the temper mill on a Tuesday afternoon with an edge defect over the last eight tonnes. Quality downgrades it from an exposed automotive grade to commercial quality. That coil was applied to a stamper's order whose delivery window closes Thursday, and it was 22 tonnes of a 60 tonne line. Four questions now need answers within the hour, and today they are answered by three people on the phone, a query somebody wrote against the level 2 database in 2011, and a spreadsheet a planner updates twice a shift.
Buying for this is hard because steel is a divergent process with continuous re identification. One heat becomes several slabs, one slab becomes a coil, one coil becomes child coils and then cut lengths, and at every step the material can change grade, owner, destination and value. Standard manufacturing software models convergence and treats material as fungible against a part number. In your mill nothing is fungible, which is why your enterprise system is excellent at purchasing and finance and blind to everything between the caster and the shipping bay.
What a steel mill software company actually does
The visible build is an order book screen and a coil list. Three deeper things determine whether it earns its cost.
Order to material matching has to run continuously rather than as a one time allocation. The useful question is never what is allocated to this order, it is what is the best assignment of all available material to all open orders right now, given tolerances, delivery windows and the cost of substitution. Every piece carries its measured attributes, thickness, width, weight, chemistry, mechanical results and surface class, and every open line carries an acceptance envelope including customer specific tolerances wider or narrower than standard. When a downgrade arrives, the system proposes re application within seconds and shows the value difference between the options. Material sitting in secondary inventory for six months is capital you already spent.
Genealogy has to survive every split and every downgrade. Model each piece as a node with parents, children and the transformation event between them, flag transition material from a mixed grade cast sequence explicitly rather than assuming a single heat, attach test results to the piece they were taken from and propagate with a visible rule. Certificates under EN 10204 3.1 then read the graph, and a recall query in either direction returns in seconds. Build it append only, because a genealogy record that can be silently edited is worth nothing in an audit.
Then the acquisition layer, which is where a large share of the effort actually goes. If the caster, the hot strip mill and the galvanising line came from three suppliers, you have three data models, three timestamp conventions, three piece identifier schemes and three opinions about what a production event is. Normalise them into one plant wide piece and event model, continuously rather than nightly, and everything downstream reads the same truth.
What it really costs in 2026
Digital Heroes delivery bands for integrated and semi integrated mills.
| Project tier | Cost | Timeline |
|---|---|---|
| Piece and event model with genealogy and certificate generation only | $70,000 to $140,000 | 10 to 14 weeks |
| First release: plant wide model, acquisition for key lines, order matching, genealogy | $120,000 to $250,000 | 16 to 24 weeks |
| Full platform: campaign scheduling, all lines, yield costing, secondary inventory, customer portal | $350,000 to $900,000 | 12 to 24 months |
| Support, new lines and practice rule changes | 15 to 20 percent of build per year | Retainer |
Two costs are almost never quoted and both are real.
The first is identifier reconciliation. The same coil carries a different number on three systems, and nobody knows how bad the mismatch is until somebody reads the data. It is slow, manual discovery work with a person from operations sitting alongside an engineer, and firms leave it out because they cannot size it from a specification document. Ask for it as a time boxed investigation before the build scope closes.
The second is the enterprise system integration going both ways. Your order book should usually stay in the system of record, which means orders flow in, applications and shipments flow back, and both directions need careful reconciliation because a disagreement about what shipped becomes a finance problem rather than a production one.
Signals of a strong partner
- They ask about transition material in the first conversation. A mixed grade cast sequence is the question that reveals whether anyone has stood in a mill.
- They name the level 2 systems they have read from. By supplier and by line type, including the ageing operator interface somebody had to scrape.
- Practice rules are data, not code. Grade sequencing, width jumps and campaign cadence change, and a scheduler should edit them without a release.
- They propose starting downstream. Order matching and genealogy from the hot mill onward pay first, and caster scheduling is easier once the piece model exists.
- They separate a sequencing tool from an optimiser. Most mills should buy the first, and an honest firm says so.
- Yield is computed per step from the piece graph. Not a planned yield percentage carried forward from standard costing.
- Repository and infrastructure in your accounts. A system running your mill for a decade should never depend on someone else's cloud account.
Red flags
- A batch and a quantity on the whiteboard. They have built warehouse software and are about to learn metallurgy at your expense.
- Nightly batch acquisition. A downgrade discovered tomorrow morning is a downgrade you could not re apply today.
- Editable genealogy. One automotive customer audit will make that decision expensive.
- A campaign optimiser proposed in phase one. Ambitious, unaffordable, and useless until the plant wide piece model is trustworthy.
- No question about customer certificate formats. Automotive and pressure equipment customers have their own formats and portals, and each is work.
Questions to ask on the first call
- Draw the material model: heat, cast sequence, slab, coil, child coil, cut length, with parents, children and transformation events.
- How do you handle transition material where a coil inherits chemistry from two heats in one cast sequence?
- Which level 2 systems have you read from, by supplier and by line, and what did the interface look like?
- The same coil has three different numbers across three systems. How do you reconcile that, and how long does it take?
- Walk through re application when quality downgrades a coil already applied to an order closing in two days.
- How does a scheduler change a grade sequencing rule without you making a release?
- How is a mill test certificate produced from the graph, and is the history append only?
- If the order book stays in our enterprise system, what flows each way and how is it reconciled?
- Who owns the repository, the infrastructure and the right to hire another firm to continue?
A simple way to decide
Buy a paid discovery phase rather than choosing from a proposal. The deliverable is a written specification you keep: the piece and event model with transformation rules, the acceptance envelope structure for order matching, the acquisition approach per line with the identifier reconciliation findings, the certificate requirements per customer, the practice rules captured from your schedulers, and a phased plan that starts downstream. Getting your schedulers' sequencing knowledge onto paper is worth the fee on its own, because right now it lives in two or three heads and some of them are near retirement.
Digital Heroes is the wrong choice for a single line re roller working to stock. An enterprise system with lot tracking and a competent spreadsheet will hold you for years, and the threshold here is complexity rather than tonnage. If you are a large integrated producer with the budget for a multi year programme and practices close to the industry standard model, PSI Metals is a serious product built by people who know steel, and you should evaluate it properly. We fit mills running lines from different equipment suppliers with nothing joining them. Digital Heroes runs PRD-first delivery, has delivered 2,000+ projects with a 50+ team, and contracts through an India LLP, a US LLC or a UK LTD so the code assigns under your own law.

Frequently asked questions
How much does custom steel mill production software cost?
A piece and event model with genealogy and certificate generation runs $70,000 to $140,000. A first release adding level 2 acquisition for your key lines and order to material matching with re application runs $120,000 to $250,000 over sixteen to twenty four weeks. A full platform with campaign scheduling, all lines, yield costing, secondary inventory and a customer portal runs $350,000 to $900,000.
Should we buy PSI Metals instead of building?
Evaluate it seriously if you are a large integrated producer with budget for a multi year programme and practices close enough to the standard model that configuration reaches them. It is a serious product built by people who know steel. Build instead when your lines come from different equipment suppliers with nothing joining them, or when licence and implementation cost is out of proportion to your mill's size.
What happens when a coil is downgraded after it is applied?
The system should re evaluate the whole applied pool, not just that order. Within seconds it proposes alternatives: another coil in the pool meeting specification, a slab that can be rolled in time, or another open order the downgraded material satisfies within tolerance. It shows the value difference between options, so a planner chooses rather than defaulting to secondary inventory at a discount.
Can we keep heat traceability through slitting and cut to length?
Yes, if genealogy is modelled as a graph with parents, children and transformation events rather than as a batch field. Slitting into child coils is simple. The hard case is transition material from a mixed grade cast sequence, which inherits from two heats and must be flagged explicitly rather than assumed. Ask any vendor how they handle it, because the answer reveals mill experience immediately.
How do you get data out of level 2 systems from different suppliers?
With one acquisition parser per line, normalising into a single plant wide piece and event model that runs continuously rather than nightly. Reading one supplier's database is different from consuming another's feed, and some mills genuinely need an ageing operator interface scraped. Price each line separately, and expect identifier reconciliation across systems to be manual discovery work before anything automated is possible.
If we build for 20 users now, will the software cope with 500 later?
It should, without a rewrite, if it was built on a standard cloud stack; going from 20 to 500 users is mostly a hosting configuration change costing hundreds a month, not a second project. What actually breaks under growth is sloppier work: database queries never indexed for volume and features designed assuming one office's worth of data. Before signing, ask the vendor what happens to the system at ten times today's data, and listen for a specific answer.
We run everything on Airtable and spreadsheets. When is it time to go custom?
The switch usually makes sense when you hit one of two walls: Airtable's record caps (125,000 records per base on the Business plan) or logic the tool cannot express, like multi-step approvals with conditional pricing. There is also a simple cost signal: 25 people on Business at roughly $45 per seat per month is about $13,500 a year, forever, for a tool you are already fighting. Custom is worth it when the workflow is core to how you make money; for peripheral processes, staying on Airtable is the right call.
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.
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.
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 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.
Should we build an MVP first or go straight to the full system?
MVP first, for almost everyone: ship the single workflow that carries the business value in 10 to 16 weeks, learn from real users, then fund phase two from evidence instead of guesses. The caveat is that an MVP is a small version of a well-built system, not a badly built version of a big one; the data model must already support what comes next. An agency that cannot tell you what they deliberately left out of your MVP has not designed one.
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 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.
Will custom software work with the tools we already use, like QuickBooks and Stripe?
Yes, and this is one of custom software's genuine advantages: QuickBooks, Stripe, Shopify, and most mainstream business tools publish documented APIs built for exactly this. Expect each standard integration to add one to two weeks of build time, and be suspicious of any quote that lists five integrations without asking what data flows in which direction. The hard cases are legacy systems with no API, which is a question to raise in discovery, not in week nine.
If an agency builds my software, who actually owns the code?
You should own everything, assigned in writing: the contract transfers full IP to you on final payment, the code lives in your GitHub organization, and hosting runs in cloud accounts you control. The red flag is a proposal that mentions the agency's proprietary platform or framework, which usually means you are renting, not buying. Digital Heroes structures every build this way precisely so a client can fire us and lose nothing but the relationship.
How much should a small business expect to pay for custom software?
Across 2,000+ Digital Heroes projects, a small business system that replaces spreadsheets or one core workflow typically lands between $40,000 and $80,000, with more complex first versions running up to $150,000. The two levers that move the number most are integrations and user roles, not the team's hourly rate. Any quote under $15,000 for a full production system means the vendor has not understood your scope yet.
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.
