A custom depot maintenance, repair and overhaul execution layer runs $110,000 to $750,000, and the number of platforms you support moves the number further than induction volume or headcount. A second airframe type is not a configuration exercise, it is a second data model conversation about configuration states, technical data structure, certification categories and back shop routing, and it carries most of a first release with it. One platform on one line prices near the floor. A mixed aviation and marine portfolio does not. A first release covering serial level as maintained configuration, controlled task issue, over and above capture with evidence and rolling re plan runs $110,000 to $220,000 over 16 to 22 weeks in Digital Heroes delivery experience.
The bands a depot execution build falls into
The first release band is $110,000 to $220,000 over 16 to 22 weeks. That covers the as maintained configuration of each specific asset as the master object for the visit, task issue that validates technician certification currency and technical order revision at the moment of issue, over and above capture at the aircraft with photographs and zone and station reference, an approval queue with value thresholds, and rolling re plan against the induction schedule.
The full platform band is $300,000 to $750,000 phased over 12 to 20 months. That adds government furnished material accountability as a distinct inventory class, tooling and calibration control, back shop routing across plating, non destructive test and paint, record package assembly from captured sign offs, contract milestone reporting, and integration with your fleet system of record.
There is a narrower opening move that pays for itself faster than anything else here. Over and above capture with evidence and threshold based approval routing, on its own, runs $45,000 to $82,000 over eight to eleven weeks. In our experience the largest recoverable loss at a depot is not productivity, it is legitimate discovery work that could not be substantiated cleanly enough to bill without a fight.
What drives a depot maintenance build up
Platform count is the first driver, and it is close to linear rather than incremental. Each additional airframe or hull type brings its own configuration structure, its own technical data hierarchy, its own certification categories and its own back shop flow.
The compliant hosting boundary is second. 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. Deciding that in the first sprint is expensive. Discovering it at a security review in month nine is far more expensive.
Offline capability is third and it roughly doubles the testing burden. It is not optional, because hangar decks, dry docks and back shops lose connectivity and any system that assumes a live connection gets worked around with paper inside a fortnight.
Integration with government systems is fourth, and its cost is measured in elapsed time as much as effort, because it moves at the pace of your customer approvals rather than yours.
Historical record migration is fifth. Decades of paper brought forward is a workstream, not a task.
What keeps the number down
Do not replace your fleet system of record. If IFS Maintenix or Ramco Aviation is holding your airworthiness record adequately, build the execution and re planning layer around it and let the record system stay the record system. Rip and replace programmes at depots have a poor history, mostly because nobody could afford to stop while they happened.
Start with one platform and one line. The second platform is materially cheaper once the configuration model exists, and proving the discovery to approval path on a single line gives you the schedule and billing evidence you need to fund the rest.
Build the discovery to approval path first and the reporting later. That is where both the schedule and the money live, and it produces measurable results inside one induction cycle.
Settle the hosting boundary before the first line of code. The architecture decisions that follow from it are cheap to make early and close to a rebuild if made late.
Keep approvals human. In a contract environment an automated approval is an audit finding waiting to happen, so do not pay to build one.
A worked example that adds up
A depot running one airframe type on a single line, roughly fourteen programmed depot inductions a year, with a fleet record system already in place and over and above work running at a significant share of hours.
- Discovery, including the as maintained configuration model and the over and above approval threshold workshop with programme management: $18,000
- As maintained configuration as the master object for the visit, with an append only change log and effectivity checked at task issue: $34,000
- Task issue with technician certification currency validation and technical order revision recorded on the sign off: $30,000
- Over and above capture at the aircraft with photographs, zone and station reference, queue with target response times and value thresholds: $38,000
- Rolling re plan against the induction schedule with schedule impact computed at the point of approval: $32,000
- Offline capture with conflict safe synchronisation for hangar deck and back shops: $26,000
- Compliant hosting boundary, testing, deployment and technician training: $22,000
That totals $200,000, in the upper half of the first release band, driven by the offline requirement and the hosting boundary rather than by induction volume. A depot with a lighter compliance posture, existing rugged devices and lower over and above share lands nearer $125,000.
Adding government furnished material accountability, tooling and calibration control, back shop routing, record package assembly and contract milestone reporting takes this depot to roughly $480,000 to $620,000 in total across the following 12 to 16 months.
How the spend phases
Discovery is three to four weeks and around 9 percent. Two deliverables matter more than screens: a written as maintained configuration model your engineering authority signs, and an approval threshold table saying which value bands move without waking a programme manager.
The configuration model carries roughly 17 percent across weeks four to ten. It cannot be retrofitted, so it goes first.
Task issue controls are about 15 percent and land alongside it, because certification and technical data currency checks depend on the same task object.
Over and above capture is the largest single line at around 19 percent, weeks eight to sixteen, and it is the piece that repays fastest.
Rolling re plan is roughly 16 percent, weeks twelve to twenty, and it needs your planners in the room weekly rather than at a demo.
Offline work is around 13 percent and should be tested by taking a device into an actual hangar with the radio off, not in a conference room. Hosting, testing and training take the remaining 11 percent, and the security review should start when development does.
The ongoing costs nobody quotes
The compliant hosting boundary is the standing cost that separates this category from ordinary enterprise software. Running production inside a boundary with restricted access, brokered support and protected audit trails costs materially more per month than a commercial cloud footprint of the same size, and it does not fall over time.
Support access is the second. Every fix requires a person who is cleared to be in that environment, which shapes both your retainer and who can staff it. Agree that in the contract rather than discovering it during an incident.
Retention and export are the third. Depot records outlive contracts, vendors and usually the software, so an export in an open readable format is a maintained capability rather than a one off deliverable. Verify it annually.
Rugged device attrition on a hangar deck is real. Buy one model, budget replacements and keep spares interchangeable.
Support and enhancement typically runs 12 to 18 percent of the build cost annually, with the enhancement half going on new platforms, revised technical data structures and new contract reporting formats.
Comparing a build against your current renewal
This comparison is not really against a license. Your fleet record system stays, so the renewal continues either way, and the build competes against operational losses you can measure.
Start with over and above. Take the last four inductions and identify the discovery work that was performed, was legitimate, and was either written off or settled below cost because the evidence chain was thin. That number is your primary case, and most depots can produce it in an afternoon from their own dispute correspondence.
Then price bay time. An asset sitting while a decision moves through email is an asset earning nothing, and you know your own day rate. Measure the elapsed hours from finding raised to work authorised on those same four inductions and multiply.
Then price government furnished material delays. A line stopped for a week waiting on customer supplied material is a schedule fact that needs to exist in writing while it is happening. Reconstructing it from emails at contract review is why those days rarely get attributed.
Finally add record package assembly. If a person spends weeks per asset chasing signatures, that is a salary line you can name.
When buying beats building
Buy if you run a single platform, your packages are largely predictable, over and above is a small share of your hours and your customer is not imposing unusual property or data requirements. Configure IFS Maintenix or Ramco Aviation properly and put the difference into tooling and people. Both are serious products with real configuration control, and Maintenix in particular is used across defense fleets for good reasons.
Buy also if you currently have no maintenance system at all. A commercial product will get you to a defensible baseline faster than a build will, and you can add an execution layer later once you know where it actually strains.
Build the execution layer when two or more of these are true: discovery work is a large share of your hours and its approval path is measured in days, your over and above billing is routinely disputed for lack of evidence, government furnished material delays are chronic and unattributed, you run multiple platforms or a mixed aviation and marine portfolio that no single product fits, or record package assembly takes weeks of a person per asset. Note that all five of those are execution problems rather than record problems, which is exactly why the answer is to build alongside your fleet system rather than to replace it.
If you would rather someone argued with your brief than agreed with it, Digital Heroes builds and runs its own products, so the people choosing your architecture live with those decisions on their own revenue. You keep the specification either way.

Frequently asked questions
What is the total cost of custom military MRO software?
A depot execution layer covering serial level as maintained configuration, controlled task issue, over and above capture with evidence and rolling re planning runs $110,000 to $220,000 over 16 to 22 weeks in Digital Heroes delivery experience. 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.
Platform count and the compliant hosting boundary are the two largest cost drivers, ahead of induction volume.
What does it cost to run each year?
The compliant hosting boundary is the standing cost, and it runs materially above a commercial cloud footprint of the same size because of restricted access, brokered support and protected audit trails. Support staffing is shaped by who is cleared to enter that environment, which affects your retainer rate as well as its size.
Support and enhancement typically runs 12 to 18 percent of the build cost annually, with the enhancement half going on new platforms and revised contract reporting formats.
How long does a first release take?
Sixteen to 22 weeks for the execution layer, then 12 to 20 months in total for the full platform. Elapsed time stretches where government system integrations are involved, because those move at the pace of your customer approvals rather than your development team.
The fastest path to a measurable result is to build the discovery to approval path first, since it produces schedule and billing evidence inside a single induction cycle.
Should we replace IFS Maintenix or build alongside it?
Build alongside it. Maintenix is a strong fleet maintenance record system, and replacing a working record system at a depot is a programme your customer will not tolerate a pause for. Ramco Aviation sits in the same position if that is what you run.
The gaps depots hit are 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 putting the airworthiness record at risk, and it costs a fraction of a replacement.
Can we build only the over and above workflow first?
Yes, and it is usually the highest return opening move. Capture with photographs, zone and station reference, the inspection requirement that surfaced the finding, and threshold based approval routing runs $45,000 to $82,000 over eight to eleven weeks.
In our delivery experience the largest recoverable loss at a depot is legitimate discovery work that could not be substantiated cleanly enough to bill without a fight. Fixing the evidence chain moves that before anything else in the build does.
Why does offline capability add so much to the price?
Because it roughly doubles the testing burden. Every capture path has to work with no connection, hold state locally, and reconcile safely when the network returns, including the case where two people edited the same record from different devices.
It is still not optional. Hangar decks, dry docks and back shops lose connectivity routinely, and a system that requires a live connection gets worked around with paper inside a fortnight, at which point your data is a month stale and the build has failed.
How much does government furnished material tracking add?
Expect $35,000 to $70,000 within the full platform for a distinct inventory class with its own ownership, condition code and document trail, linked to the task waiting on it, plus the delay attribution reporting.
The reporting is the part that pays. Because material you do not own is free to the contractor, it often escapes the inventory discipline applied to purchased parts, which makes chronic delays structurally invisible and therefore hard to argue at contract review.
How do controlled unclassified information rules change the budget?
They change architecture rather than features, which is why they have to be decided in the first sprint. Hosting boundary, access population, support brokering, audit trail immutability and export format all follow from that decision, and retrofitting a boundary late is close to rebuilding.
Expect the boundary itself to be a visible line in both the build and the monthly run cost. Ask any prospective developer where production runs and who can reach it before you compare quotes, because a proposal that ignores it is not comparable.
What is the cheapest credible version of this system?
Around $110,000 for a depot with one platform, one line, an existing fleet record system, rugged devices already in service and a moderate compliance posture. That buys the as maintained configuration model, controlled task issue, over and above capture with evidence and rolling re plan.
Treat a materially lower quote with caution if it still promises offline capture and a compliant hosting boundary. Those two lines carry most of the engineering and neither can be added cheaply afterwards.
What mistakes kill ERP projects most often?
The three we see most in rescue work at Digital Heroes: recreating the old system's broken process in new software, launching everything at once instead of module by module, and having no single internal owner with authority to decide. A fourth is skipping the parallel run on data migration to save two weeks, which trades a short delay for months of distrust in the numbers. None of these are technical failures, which is why vendor selection should weigh process discipline over demo polish.
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.
What does it cost to maintain a custom ERP each year?
Budget 15 to 20 percent of the original build cost per year, so a $150,000 ERP needs roughly $22,000 to $30,000 annually for hosting, security patches, integration upkeep, and small improvements. Across Digital Heroes maintenance contracts, third-party APIs changing is the biggest recurring work item. That total still usually sits well under the license bill for a comparable NetSuite or Dynamics seat count.
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.
How do we migrate years of data from our old system without losing anything?
Through a staged migration with a parallel run, never a single cutover weekend. The data gets extracted and cleaned early, loaded into the new ERP while the old system stays live, and both run side by side for two to four weeks so your team can verify counts, balances, and open orders match. In Digital Heroes ERP projects, data cleaning consistently takes longer than the technical transfer, so it starts in week one, not at the end.
How small can the first version of my software be and still be worth building?
One workflow, end to end, for one type of user: the single process that currently burns the most hours or loses the most money. In Digital Heroes delivery experience, first versions scoped to 6 to 10 weeks of build time ship, get used, and generate the feedback that makes version two obviously right, while 9-month first versions routinely launch with features nobody touches. Everything you cut from v1 gets cheaper to build later, because real usage reorders the roadmap for you.
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.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it.
