Pick the firm that can explain how an as maintained configuration differs from a bill of materials. If those are the same thing to them, they will model your fleet as a product catalogue. Expect $110,000 to $220,000 and 16 to 22 weeks for a depot execution layer alongside your existing record system, and settle the hosting boundary in the first sprint rather than at a security review.
Hiring a depot software partner has the shape of an induction. You sign against a planned package, the panels come off in week two, and the real scope turns out to be whatever was underneath them: an integration nobody surveyed, a data model that does not fit a second platform, an approval chain that runs through a customer whose timelines you do not control. The plan you contracted against stops being true early, and the only question that matters is whether the arrangement can absorb discovery without a renegotiation every time.
What makes this category hard to buy is that commercial aviation software looks like an obvious fit and is not. Airline products assume scheduled maintenance with bounded variability, parts you own, and a work order that becomes an invoice. A depot has discovery as the main event, government furnished material with its own accountability, a scope baseline against which claims are made, and a record package that has to stand up for decades. A vendor who has delivered for airlines will be fluent and still wrong in the four places that cost you money.
What a depot software partner is really signing up for
They make the as maintained configuration of the specific asset the master object for the visit. Two airframes of the same model in the same hangar can differ by a decade of modifications applied in different sequences and components with their own life histories. Every task, part fitted, serial removed and modification embodied records against that asset in an append only log, and effectivity checks run at task issue rather than at package build, so work that no longer applies never reaches a technician.
They build the discovery path first, because that is where both the schedule and the money live. A finding raised at the aircraft with photographs, zone and station reference, the affected configuration item and the inspection requirement that surfaced it, moving through a queue with thresholds so small items do not wake a programme manager and larger ones travel upward with the schedule impact already computed.
They treat government property as its own inventory class with ownership, condition code and document trail, linked to the task waiting on it, and produce a delay attribution report while the line is stopped rather than reconstructing it from emails at contract review.
And they capture sign off at the moment of work, with the technician's certification validated then and the technical order revision recorded as part of the signature, so the record package assembles from data you already hold.
What it really costs in 2026
These bands come from Digital Heroes delivery experience on regulated maintenance and evidence systems.
| Scope | Cost | Timeline |
|---|---|---|
| Over and above capture and evidence only, feeding your existing systems | $60,000 to $120,000 | 10 to 14 weeks |
| Depot execution layer: serial level configuration, task issue controls, discovery workflow, rolling re plan | $110,000 to $220,000 | 16 to 22 weeks |
| Full platform: GFM accountability, tooling and calibration, back shop routing, record package assembly, contract reporting | $300,000 to $750,000 | 12 to 20 months |
| Each additional platform or airframe type | $40,000 to $120,000 | 6 to 12 weeks each |
Two lines are usually missing. The first is the compliant hosting boundary. Maintenance records in a defense context are frequently controlled unclassified information, which shapes where production runs, who can reach it, how support access is brokered and how the audit trail is protected from edit. Retrofitting that after the build is close to starting again, so a proposal that defers it to a later security review has deferred a large cost, not removed it.
The second is offline. Hangar decks, dry docks and back shops have unreliable connectivity, and offline capable capture roughly doubles the testing burden. Vendors quote the feature and price the happy path. Ask for the test plan, not the promise.
Signals of a strong partner
- They propose to coexist with your record system, not replace it. Rip and replace at a depot fails because nobody can afford to stop while it happens.
- They can define as maintained configuration without prompting. And explain why effectivity has to be checked at task issue rather than at package build.
- They design the evidence chain, not the invoice. Photographs, zone and station, inspection requirement, person and timestamp attached to the finding at the moment it is raised.
- Certification currency gates task assignment. A technician whose qualification lapsed last week cannot be issued a task that requires it, and the check happens at issue.
- Technical order revision is recorded in the signature. Correct work performed against a superseded revision is still a finding, and this is a cheap control to build.
- Government furnished material has its own record. Ownership, condition code and document trail, with delay attribution produced while the line is stopped.
- They raise the compliance boundary in the first conversation. Where production runs, who can access it, how support is brokered, and how the audit trail resists edits.
Red flags
- Configuration and bill of materials used interchangeably. Your fleet becomes a product catalogue and you discover the difference during the first modification embodiment.
- A proposal to replace the fleet record system. That is a programme your customer will not tolerate a pause for, and it puts the airworthiness record at risk for no operational gain.
- Offline described as a nice to have. Paper returns within a fortnight and your data goes a month stale, which is exactly the failure the system was bought to prevent.
- Automated approval of over and above work. In a contract environment that is an audit finding waiting to happen. Approvals stay human even when the estimate is automated.
- Compliance handled at the end. A hosting boundary decided after development is a crisis in month nine and a rebuild in month ten.
Questions to ask on the first call
- Define an as maintained configuration and tell me how it differs from a bill of materials.
- A modification was embodied last Tuesday. How does the system stop a now inapplicable task reaching a technician today?
- Walk me through a corrosion finding from discovery to approval to billing evidence.
- How is government furnished material recorded, and how do you attribute a line stopped eleven days waiting on it?
- How is technician certification currency checked, and at what moment?
- How does a task sign off capture the technical order revision that was actually used?
- How will you coexist with our existing fleet record system, and which direction does each object flow?
- Where does production run, who can access it, how is support access brokered, and how is the audit trail protected from edit?
- What export format will let us read these records in twenty years, and who owns the repository from day one?
A simple way to decide
Buy a paid discovery phase rather than picking from proposals. Two to four weeks, priced separately, producing a written specification: the as maintained configuration model, the discovery to approval workflow with thresholds and evidence requirements, the government property model, the coexistence design with your record system including object ownership in each direction, the compliance boundary and access model, the offline approach with its test plan, and a fixed price for the first release on one platform and one line.
Insist the specification is yours whoever builds it. On a depot programme it has an unusual second value: it is the document your customer's diligence will ask for, and having the configuration model and audit trail design written down before a single screen exists tends to shorten conversations that otherwise run for months.
Digital Heroes delivers PRD first, hands over the repository and hosting accounts from the first commit, and contracts through India LLP, US LLC and UK LTD entities so intellectual property assigns under the buyer's own law. Depot records outlive contracts and vendors, so both the system and a readable export should be yours from the start.

Frequently asked questions
How much does custom military MRO and depot maintenance software cost?
A depot execution layer with serial level configuration, task issue controls, over and above capture and rolling re planning runs $110,000 to $220,000 over 16 to 22 weeks. Adding government furnished material accountability, back shop routing, record package assembly and contract reporting runs $300,000 to $750,000 across 12 to 20 months. The number of platforms and the compliant hosting boundary are the two largest cost drivers.
Should we replace our fleet record system or build alongside it?
Build alongside it. Products like IFS Maintenix are strong fleet maintenance record systems, and replacing a working record system at a depot is a programme your customer will not tolerate a pause for. The gaps depots hit are at execution level: over and above evidence, government property accountability, technical data currency and back shop routing. An execution layer that reads and writes to the record system addresses those without risking the airworthiness record.
How do we make over and above work billable without a dispute?
Capture evidence at the moment of discovery rather than reconstructing it later. The finding should carry photographs, zone and station reference, the affected configuration item, the inspection requirement that surfaced it, the person, the timestamp and the approval that authorised the work. When the claim is assembled the evidence is already attached. Unbillable discovery work usually fails on evidence rather than on legitimacy.
What do quotes for depot software usually leave out?
The compliant hosting boundary and the true cost of offline capability. Maintenance records are frequently controlled unclassified information, which shapes where production runs, who can reach it, how support access is brokered and how the audit trail resists edits, and retrofitting that is close to a rebuild. Offline capture also roughly doubles the testing burden, and vendors tend to price the feature rather than the test plan.
Who should own the code and the maintenance records?
You should own the repository, the hosting accounts and an export in an open, readable format, written into the contract before kickoff. Depot records outlive contracts, vendors and often the software itself, so the ability to read your own data in twenty years is a requirement rather than a commercial nicety. Confirm the export format during discovery instead of discovering it at the end of the engagement.
Will a custom ERP scale as we grow from 50 to 500 employees?
Yes, if it is designed for that from the start, which mostly means clean database design, permissions that handle new departments, and modules that stay separable. Adding users to software you own costs nothing in licenses, the opposite of the per-seat scaling penalty on NetSuite or Dynamics. What does need budget as you grow is new modules and integrations, so keep a small standing development arrangement rather than restarting a vendor search every two years.
Is SAP overkill for a mid-sized company?
For most companies under about 500 employees, yes. SAP S/4HANA is built for multi-entity, multi-country enterprises with implementations measured in years and seven figures, while SAP Business One, the mid-market product, still forces your processes into its mold. If your competitive edge lives in how you operate, a custom ERP scoped to your actual workflows ships faster and costs a fraction of an SAP program.
Is customizing Odoo cheaper than building an ERP from scratch?
Usually yes in year one, and often no by year three if your workflows sit far from Odoo's assumptions. Odoo's published pricing starts around $25 per user per month and the Community edition is free, but heavy customization means every version upgrade can break your modules and needs paid rework. If you expect to rewrite more than about a third of the core flows, a scratch build with clean ownership tends to cost less over the life of the system.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.
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.
Should I pick Microsoft Dynamics 365 Business Central or build a custom ERP?
Pick Business Central if you already live in the Microsoft stack, your processes are close to standard, and around $80 per user per month for Business Central Essentials stays affordable at your headcount. Build custom when your revenue-driving workflow, such as custom manufacturing steps or unusual pricing logic, would need heavy extension work anyway. In our experience, once Dynamics customization quotes pass about $100,000 the custom option deserves a serious side-by-side.
What does it cost to keep custom software running after launch?
Budget 15-20% of the original build cost per year, which on a $100,000 system means $15,000 to $20,000 for security patches, dependency updates, bug fixes, and small improvements as real usage reveals what the spec missed. Cloud hosting for a typical business application adds $50 to $300 a month on top. Skipping maintenance does not save the money; in Digital Heroes rescue work, unmaintained systems typically need a far more expensive rebuild within about three years.
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.
How many SaaS seats do we need before building custom becomes cheaper?
The crossover usually shows up between 20 and 50 seats on premium tiers. Salesforce Enterprise lists at $165 per user per month, so 40 users cost about $79,000 a year in subscriptions, which is real money against a custom system you would own outright. Run the comparison over three years: if subscription spend beats the build cost plus 15-20% annual maintenance, custom wins on price before you even count workflow fit.
Why do companies replace NetSuite with custom software?
The three reasons we hear most at Digital Heroes are per-user license growth, SuiteScript customizations that became fragile, and workflows the platform cannot model without workarounds. A company adding 50 users to NetSuite takes on roughly $59,000 per year in extra licenses at the commonly quoted $99 per user rate, which is often the moment the custom math starts winning. Replacements usually keep the accounting structure intact and migrate module by module.
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.
Who can build a custom ERP software system?
Digital Heroes builds custom ERP 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 ERP 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.
