Government & public sector app development cost
A citizen-facing service — apply, pay, upload, track — costs $95,000 to $190,000 to build in the US. A permitting or benefits platform with caseworker review, document workflow and records integration runs $250,000 to $600,000. Accessibility conformance and procurement documentation are real, mandatory line items here, typically adding 20–35% over an equivalent commercial build.

Why government & public sector software costs what it does
The things that move the number in this vertical, which are usually not the features.
Accessibility is a legal requirement
Section 508 and ADA conformance are contractual obligations with real consequences, not best-effort goals. Building to WCAG 2.2 AA from the start adds 8–12%; retrofitting it later costs several times that and often requires redesign.
Procurement and documentation
Public sector delivery carries documentation, review gates, security assessment and reporting that commercial projects do not. This is genuine work — expect 15–25% overhead over an equivalent private-sector build.
Identity proofing
Verifying that an applicant is who they claim to be, at scale, without excluding people who lack documents or credit history, is one of the harder problems in public-sector software.
Realities to plan around
- Every citizen-facing service must work for people on old devices, slow connections and assistive technology. That is the actual constraint, and it rules out a lot of fashionable front-end architecture.
- FedRAMP authorisation, where required, is a programme costing well into six figures and taking a year or more. State and local requirements are lighter but rarely absent.
- Records retention and public disclosure obligations shape the data model — you often cannot delete things.
- Multilingual support is frequently mandatory rather than optional.

Government & public sector cost, answered
How much does it cost to build a government & public sector app in the US?
It depends far more on scope than on the sector, and quoting a single figure here would be the least useful thing this page could do. What government & public sector does decide is the floor: 5 compliance regimes may apply, you will be asked to integrate with roughly 5 systems of record, and 5 distinct roles typically touch the workflow — all of that before a single feature. The calculator below is already set to this sector; answer the rest and it returns a cost range, hours, timeline, team and running costs for your own scope.
How much does Section 508 / WCAG conformance add?
Roughly 8–12% if you build with it from the start: semantic structure, focus management, keyboard operation, contrast discipline, screen-reader testing and a published conformance report. Retrofitting it into a finished product costs two to four times that, because the fixes are often structural rather than cosmetic. For public-sector work it is a contractual requirement, so treat it as scope rather than polish.
How accurate is this estimate?
It is a planning estimate, not a quote. The band shown is roughly plus or minus 15–20% for a well-defined scope, and wider while requirements are still moving. It is built from engineering hours per discipline, converted at our blended delivery rate, so the hours are directly comparable to a real proposal line by line — but a firm price needs a technical specification, which is the step after budgeting.
Does this include hosting and maintenance?
No, deliberately. The headline figure is one-off development cost. Monthly cloud infrastructure, metered vendor fees and annual maintenance are calculated separately and shown alongside it, because they are recurring operating costs rather than capital build cost. Adding them together produces a number that means nothing.
