What is Annual Maintenance Contract (AMC)?
The recurring agreement that keeps delivered software healthy after go-live — updates, security patches, compatibility maintenance, and operational support for an annual fee.
Also known as
Annual Maintenance Contract (AMC) — explained.
An Annual Maintenance Contract (AMC) is the operating agreement that follows a delivered software engagement: for a yearly fee — typically 18–22% of the original engagement value — the vendor keeps the system healthy in production. A well-drawn AMC covers four things. Corrective maintenance: defects fixed with defined severity levels and response times. Security maintenance: patches for vulnerabilities in the application and its dependency stack, on a committed cadence — for a communications platform this is the load-bearing clause, since cryptographic libraries, mobile operating systems, and threat landscapes all move. Adaptive maintenance: compatibility with the world changing around the software — new mobile OS releases, browser updates, infrastructure upgrades — so the system does not silently rot. Support: named channels, response commitments, and escalation paths for the operator's IT team. The AMC model pairs with one-time licence delivery as the ownership-oriented alternative to SaaS subscriptions: instead of renting seats forever at per-user-per-month rates that compound with headcount, the operator buys the engineered asset once ([fixed-fee](/glossary/fixed-fee-engagement) delivery) and pays a predictable annual percentage to keep it maintained. Procurement teams favour it because it budgets cleanly and caps vendor dependency; the discipline to demand alongside it is an exit posture — documentation, runbooks, and operator training such that the organisation could run the system itself if the relationship ended (see [exit window](/glossary/exit-window)). Zeour sells every NOVARYX deployment this way: one-time engagement, AMC in force from go-live, operator self-sufficiency as the designed end-state rather than an afterthought.
Why operators care about annual maintenance contract (amc).
Software is healthiest the day it ships and decays from there unless maintained — dependencies age, platforms update, vulnerabilities surface. The AMC is what converts a delivered project into a supported operational system, with the costs known in advance and the exit door documented.
Buyer's checklist
- Security-patch cadence committed in writing, covering the dependency stack
- Defined severity levels, response times, and escalation paths
- Adaptive maintenance for OS, browser, and infrastructure changes included
- AMC percentage and scope fixed at contract, not renegotiated annually
- Exit posture: documentation and training sufficient for operator self-sufficiency

Fixed-Fee Engagement
Engagement ModelA delivery model where price is fixed per phase or per milestone — not time-and-materials — so the operator knows the cost before committing to the next stage.
Exit Window
Engagement ModelA defined post-engagement period — typically 90 days — during which the vendor supports the operator running the system independently before the contract ends.
White-Label Software
Engagement ModelSoftware engineered by one company but delivered entirely under another's brand — the buyer's name, identity, and terminology, with no vendor branding in the product.
