Hire on how the firm models the flight record and how it plans to recover your undocumented apron rules. A first release covering source arbitration into one authoritative record, constraint-based stand allocation and a tenant publish layer runs $120,000 to $260,000 over 16 to 24 weeks. The schedule risk is rarely code. It is legacy interface archaeology and time with your allocators.
Extending an airport operational database is like re-laying the drains under a terminal that cannot close. The work is invisible from the concourse, everything downstream depends on it, and you learn whether it was done properly the first morning a stand is blocked, an aircraft holds for eleven minutes, and a landing fee three weeks later gets disputed because the weight was taken from a registration that never flew.
What makes this category hard to buy is that most of the specification does not exist yet. Your flight data arrives from the airline schedule, from air traffic feeds, from the ground handler, from surveillance and from a human on the apron radio, and there is no written rule saying which one wins for which field. Your stand rules live in the heads of two allocators who have worked there fifteen years. So a vendor quoting a fixed price is pricing a scope nobody has read, and the honest ones say so.
What an airport operational database development company actually does
The demonstrable part is a gantt of stands and a flight list. The work that determines whether the platform survives is arbitration, geometry and publishing.
Arbitration means an explicit, versioned, testable rule set: accept registration from the airline until a defined point before estimated landing and then freeze it, accept actual on-block from the handler unless surveillance disagrees beyond a tolerance and then raise an exception rather than silently pick a winner, and never allow a billing-relevant field to change after invoicing without an audit entry. Every field on the flight record carries its source, its timestamp and the rule that let it win. Built as an append-only event log rather than a mutable row, that record is what lets you replay a disputed movement instead of arguing from memory.
Geometry means your apron loaded as data rather than assumptions. Adjacency pairs where a code E aircraft blocks the neighbouring stand, MARS positions that split or combine, wingspan and tail height limits, pushback conflicts on a shared taxilane, jet bridge compatibility by door position, tow cost thresholds that decide whether a four-hour turn stays contact or goes remote, border control routing and de-icing pad access. A solver rebuilds the plan in seconds when a runway closes, and the allocator arbitrates twenty genuinely hard cases instead of two hundred. The manual override stays, but it records a reason that feeds back into the rules.
Publishing means one documented event stream with a small number of supported shapes, including IATA AIDX for partners who can consume it and a plain API for those who cannot, replacing the graveyard of scheduled file exports that break silently. It is unglamorous, and it is usually the piece that convinces the operations team the platform is real.
What it really costs in 2026
These bands assume production use by the apron and allocation teams, not a pilot.
| Project tier | Cost | Timeline |
|---|---|---|
| Source arbitration into one authoritative flight record, constraint-based allocation, tenant publish layer | $120,000 to $260,000 | 16 to 24 weeks |
| Adds aeronautical billing with versioned tariffs and resource allocation for desks and belts | $220,000 to $480,000 | 7 to 12 months |
| Full platform with A-CDM milestone emission, tenant portal and multi-terminal operating models | $300,000 to $800,000 | 9 to 18 months |
| Support, tariff maintenance and new tenant onboarding | 15 to 22 percent of build per year | Retainer |
The first missing line item is legacy interface archaeology. A baggage handling interface or a surveillance feed installed a decade ago has local customisation nobody documented, and the specification sometimes has to be bought back from the original integrator before a single line of code can be written. Price each of those as its own small project with its own vendor relationship rather than as a line inside the build.
The second is rule discovery, and it is calendar time rather than developer time. Writing down what your allocators actually do takes weeks of their attention during shifts they are already working, and no amount of engineering capacity compresses it. A quote that shows a two-week discovery phase for a two-terminal airport has not met your allocators.
Signals of a strong partner
- They separate the scheduled flight, the operational movement, the turnaround and the resource assignments. A single flights table with an editable status column is a booking system wearing a high-visibility vest.
- They ask which source wins for which field before discussing screens. Arbitration is the product, and they know it.
- They want your apron geometry as data. Adjacency, MARS behaviour, wingspan codes, bridge compatibility and tow thresholds get requested in the first workshop.
- Tariffs are versioned data, not code. A mid-year charge change should need no release, and every invoice line should link to the record and rule version that produced it.
- They plan the publish layer early. One documented stream with AIDX and an API beats another scheduled export from a machine under someone's desk.
- They name the systems they have integrated and the protocol used. Type B messaging, AIDX, a baggage interface, a surveillance feed and a finance system are five different failure modes.
- Ownership is settled before kickoff. Airports buy systems that live fifteen or twenty years. Digital Heroes hands over the repository and cloud accounts from the first commit and would tell you to walk from anyone who hedges.
Red flags
- A fixed price before anyone has spoken to an allocator. The rules are the scope, and they are not written down anywhere yet.
- They propose replacing your vendor AODB in year one. For most mid-sized airports the right answer is to build the arbitration and allocation layer around it.
- Integrations are described in general terms. Ask for system names and message types. Vagueness here always becomes a change order.
- Billing is computed from a monthly export. That is the mechanism that loses movements, uses stale weights and cannot evidence parking durations.
- No exception queue in the design. Without it, contradictory sources get resolved silently, which is how a dispute becomes unanswerable.
Questions to ask on the first call
- Model our flight record on this whiteboard. Where does the turnaround sit?
- Which source wins for registration, for actual on-block, and for passenger figures, and who decides?
- What happens when surveillance and the handler disagree by four minutes?
- How would you express a MARS stand and an adjacency restriction as data rather than as code?
- When a runway closes for two hours, what does the allocator see and how long does the replan take?
- How does an invoice line prove which record and which tariff version produced it?
- Which baggage handling or surveillance interfaces have you worked with, and how did you get the specification?
- How long do you need with our allocators before you can quote the allocation work honestly?
- How does a new tenant get flight data next year without us commissioning another export?
A simple way to decide
Do not pick a builder from three quotes. Buy a paid discovery phase whose deliverable is a written specification you own: the flight record model, the arbitration rule set field by field, the apron geometry captured as data with your allocators signing it off, an inventory of every tenant feed and legacy interface with its owner and its cost to open, the tariff catalogue, and a phased plan that leaves the vendor AODB in place. Four to six weeks with your operations team in the room produces a document worth more than the quotes it replaces.
After that, comparison is straightforward, because every firm is bidding on the same written scope and the differences are visible. Digital Heroes runs PRD-first delivery and hands over that document either way, so the discovery is not something you buy twice.

Frequently asked questions
How much does it cost to hire a company to build airport operations software?
A first release covering source arbitration into one authoritative flight record, constraint-based stand allocation and a tenant publish layer runs $120,000 to $260,000 over 16 to 24 weeks. Adding aeronautical billing with versioned tariffs and resource allocation takes it to $220,000 to $480,000. A full platform with A-CDM milestones and a tenant portal reaches $300,000 to $800,000. Legacy interfaces are the biggest single variable.
Can we keep our existing AODB and hire someone to build around it?
Yes, and for most mid-sized airports that is the better answer. Keep the vendor system as the record for the fields it holds well, then commission the arbitration rules, stand allocation and publish layer around it so your local constraints and integrations belong to you. This avoids a migration that would consume two years. The integration boundary needs designing carefully so the vendor system is never bypassed without anyone noticing.
Why does discovery take so long on an airport project?
Because the specification lives in people rather than documents. Your stand and resource rules are usually held by two long-serving allocators and have never been written down, and legacy interface specifications sometimes have to be recovered from the original integrator. That is calendar time competing with shifts those people are already working, and adding developers does not compress it. Airports with documented apron rules move noticeably faster and pay less.
How do I tell a serious airport developer from a general software firm?
Ask them to model the flight record on a whiteboard. A serious firm separates the scheduled flight, the operational movement, the turnaround linking arrival to departure, and the resource assignments, then immediately asks which source wins for which field. A firm that draws one flights table with an editable status column has built booking systems and is about to learn aviation at your expense during a live operation.
Who should own the code, and does it matter at an airport?
It matters more here than almost anywhere, because airports operate systems for fifteen or twenty years and tenant dependencies accumulate. You should own the repository, the cloud infrastructure accounts and the unrestricted right to hire another firm, agreed before kickoff rather than during contract review. At Digital Heroes the code is yours from the first commit, contracted through an India LLP, a US LLC or a UK LTD as your jurisdiction requires.
How much does a custom ERP cost for a small business?
A small-business ERP covering two or three core modules typically runs $40,000 to $120,000, with inventory, ordering, and accounting sync being the usual starting set. Across 2,000+ Digital Heroes projects, integration count and user roles drive cost far more than screen count. A full mid-market ERP with six or more modules usually lands between $150,000 and $400,000.
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.
What should I prepare before contacting an ERP development agency?
Bring a list of your current tools and spreadsheets, a rough map of how an order or job moves through the company today, your user count by role, and the three problems costing you the most hours. You do not need a formal specification; a good agency writes that with you during discovery. Companies that arrive with those four things typically cut two to three weeks off scoping in our experience.
What happens to my ERP if the agency shuts down or we part ways?
If ownership was set up correctly, nothing breaks: you hold the source code, the system runs in cloud accounts you own, and handover documentation lets a new team take over. Insist on repository access from day one, admin ownership of all hosting and third-party accounts, and documentation as a contract deliverable rather than a favor. This is the single most important clause to check before signing an ERP contract.
Can I start with one ERP module instead of the full system?
Yes, and it is how most successful custom ERP projects at Digital Heroes begin. We build the single module causing the worst pain first, typically inventory or order management, get it live in 10 to 14 weeks, and let it prove ROI before the next phase gets funded. Starting with one module also derisks data migration because you move one dataset at a time.
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.
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 an agency for an ERP project?
Ask to speak with two clients who have been running an ERP the agency built for at least two years, because ERP quality shows up in year two, not at launch. Then ask for their data migration plan, their module rollout sequence, and the named senior engineers who will be on your project. An agency that leads with screen designs instead of process mapping is a red flag for ERP work.
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.
How many developers does it take to build an ERP?
A typical Digital Heroes ERP pod is five to seven people: two or three backend engineers, one frontend engineer, a QA engineer, a project manager, and a part-time architect and designer. Bigger teams rarely go faster on ERP because the bottleneck is decisions about your business rules, not typing speed. What you need on your side is one empowered internal owner who can answer process questions within a day.
Does it matter which tech stack the agency wants to use?
Yes, but not in the way most buyers expect: the goal is boring, popular technology such as React, Node.js or Python, and PostgreSQL, because any future team can maintain it and hiring a replacement developer takes days, not months. The red flag is an agency-proprietary framework or an unusual language, which welds you to that one vendor no matter what your contract says about code ownership. A useful test: could you find three freelancers fluent in this stack within a week? If not, push back.
Can a custom ERP integrate with the tools we already use, like QuickBooks or Shopify?
Yes, and keeping tools that already work well is usually the right call. The integrations we build most often are QuickBooks or Xero for accounting, Shopify or WooCommerce for orders, ShipStation for fulfillment, and Salesforce or HubSpot for CRM. A typical integration adds $5,000 to $15,000 to the build depending on how much two-way syncing the workflow needs.
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.
Can a custom ERP meet compliance requirements like SOC 2 or GDPR?
Yes, and often more cleanly than a shared SaaS platform because you control exactly where data lives and who touches it. The build includes role-based access control, full audit logs, encryption at rest and in transit, and data residency in whatever region your regulator requires. If you need SOC 2 attestation, tell the agency before development starts, since audit logging is far cheaper to design in than to bolt on.
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.
