“How much does custom software cost?” has no single answer — it depends on what you're building and how much of it you build first. But the cost is predictable once you understand the handful of things that actually move the number. Here's how to think about it as a Miami business, and how we price it at Hayes Projects.
Custom software cost is driven by scope, not by hours in the abstract. Four things move the number the most: how many distinct features the product needs, how many external systems it has to integrate with (payments, CRM, accounting, third-party APIs), how much custom logic or data modeling is involved, and the level of design and polish the product demands.
A single-purpose tool — a configurator, a calculator, an internal dashboard — is far cheaper than a multi-role platform with billing, permissions, and integrations. The fastest way to control cost is to narrow the first version to the one workflow that creates the most value.
There are two common models. Fixed fee: the scope is defined up front and you pay a set price for that scope — predictable, best when the problem is well understood. Co-investment / equity: the studio invests part of its work in exchange for a stake, which suits ventures where you're building a product to sell, not just an internal tool.
At Hayes Projects we work in both models and tell you in a short call which one fits. Before any build, we run a brief paid validation phase (1–2 weeks) that defines scope, technical risk, and deliverables — so the price is based on a real plan, not a guess.
Location affects cost less than people expect — what matters is scope and who builds it, not the zip code. The real trade-off is between a local partner you can meet and coordinate with in your own time zone, and cheaper offshore teams where the savings often evaporate into miscommunication, rework, and hard-to-reach support.
Hayes Projects is based in Miami and works with companies across the United States, Latin America, and Spain — remote-first, in person when it helps. You get a partner in your time zone and language without paying big-agency overhead.
The biggest cost mistake is trying to build everything at once. Ship a working MVP that does one thing well, put it in front of real users, and let what you learn fund the next phase. We target 6 to 8 weeks for a working MVP in production, then build in 4-week phases with something usable at the end of each one.
That phased approach means you're never paying for a year of development before seeing whether the product works — and you keep the code, documentation, and infrastructure at every step.
Upfront, usually yes. Over time it can be cheaper — you stop paying per-seat fees forever and you own an asset built exactly for your workflow. The right choice depends on how specific your needs are; see our guide on building vs. buying.
Yes, for well-defined scope. We define that scope in a short paid validation phase first, so the fixed price reflects a real plan rather than an estimate.
6 to 8 weeks for a working MVP in production for most projects. Larger builds ship in 4-week phases, with something usable at the end of each phase.
