Maintenance
What does custom software maintenance cost per year?
Maintenance costs depend entirely on what you've built and how much it changes—there's no hidden subscription.
Any savings, efficiency gains, maintenance needs, or financial return depend on the client’s documented workflow, costs, scope, and signed agreement. Sierra does not promise a specific financial outcome.
Why there's no standard price
Maintenance is tied directly to what your software does and how often business needs shift. A simple internal tool that sits stable for a year might need almost nothing. A client portal that integrates with three external systems and gains new features quarterly costs more to keep running smoothly. This is actually good news: you're not paying for a subscription tier you don't use.
The real cost trap most teams fall into is the opposite problem. They build software in-house or with a freelancer, then realize they have no one to call when something breaks, integrations fail, or they need a quick fix. That downtime costs far more than planned maintenance ever would.
What maintenance actually covers
When you work with Sierra for ongoing support, the team handles:
Bug fixes and stability monitoring
Security patches and dependency updates
Connecting new third-party tools or APIs your business starts using
Small feature additions or tweaks based on how your team actually uses the software
Performance tuning if the system slows down as data grows
You're not locked into a bloated plan. Many clients pay month-to-month or set retainer hours—say 20 hours per month—and use them as needed. Some months they're untouched. Other months a critical integration fails and those hours cover the fix.
The cost of not maintaining
Here's where maintenance becomes cheap: consider the alternative. A payment processor updates their API and your integrations break without warning. Your team can't process orders or pull client data. Or your software sits unchanged for two years while security holes accumulate, and a breach exposes customer information.
Even "set it and forget it" systems degrade. Third-party services evolve, browser standards change, hosting environments update. What worked flawlessly in month one may start failing in month twelve if no one is watching. The cost of an emergency call at 2 a.m. to fix a live production issue far exceeds the cost of planned quarterly maintenance.
project-specific deliverables transfer after full payment under the signed agreement, subject to Sierra materials and third-party components
A critical distinction: Sierra builds custom software and project-specific deliverables transfer after full payment under the signed agreement, subject to Sierra materials and third-party components. That means you're never trapped. If maintenance costs become a problem, you can hand the codebase to another developer, maintain it internally, or walk away. You're not paying a vendor tax forever. This freedom also means you can shop around for the best support price and service fit as your needs evolve.
Any savings, efficiency gains, maintenance needs, or financial return depend on the client’s documented workflow, costs, scope, and signed agreement. Sierra does not promise a specific financial outcome.
What to expect in your first year
Most teams need a bit of support in the months after launch—final tweaks, edge cases they didn't anticipate, integration fine-tuning. Maintenance drops off significantly once the software is proven and stable. After that, you're paying for genuine changes: new features, new connections, new business needs. Growth creates maintenance costs, which is the opposite of a problem.
Next step
The real number for your situation depends on your specific system. A CRM for five users has different maintenance needs than an automated fulfillment system managing hundreds of transactions daily. That's why Sierra starts every project with a written scope review. during that written review, you can ask about long-term support and get a realistic sense of what ongoing maintenance would actually cost for your use case. The team can also discuss support options—whether that's retainer hours, pay-as-you-go, or another arrangement that matches your budget.
