If you've ever hired a developer or an agency, you've probably been quoted an hourly rate. Sixty, eighty, a hundred and fifty pounds an hour. The pitch sounds reasonable: you only pay for the time it takes. But hourly billing has a fundamental problem that nobody talks about until you're staring at an invoice that's three times what you expected.
At JMS Dev Lab, we don't bill by the hour. Every project is fixed-price. Here's why that matters to you.
Hourly billing creates a conflict of interest between you and the team building your software. The longer the project takes, the more they get paid. The faster they finish, the less they earn. That's not a recipe for efficiency.
Now, most developers aren't deliberately dragging projects out. But incentives matter. When every conversation, every email, every meeting is billable, things naturally take longer. There's less motivation to find the simplest solution. There's less pressure to make decisions quickly. And there's a subtle pull towards complexity, because complex work generates more hours.
As the client, you're in an impossible position. You can't judge whether 40 hours was reasonable for a feature because you don't know how long it should take. You can't challenge an invoice without the expertise to assess it. You're trusting that the developer is being efficient, but you have no way to verify it.
Hourly billing also creates costs that never appear on a timesheet. There's the anxiety of watching the clock — knowing every question you ask costs money. So you stop asking questions. You hold back feedback. You approve things you're not sure about because raising a concern means more billable hours.
That's terrible for the end result. Good software comes from good communication. When the client is afraid to talk to the developer, the software suffers. Features get built to spec rather than to need, because the spec was written before anyone truly understood the problem.
There's also scope creep to consider. With hourly billing, scope creep isn't a problem for the developer — it's a revenue stream. "Sure, we can add that" is easy to say when every addition means more hours. Without a fixed budget forcing prioritisation, projects bloat.
Fixed-price is simple: we agree on what we're building, we agree on the price, and that's what you pay. No surprises, no overruns, no invoices that make your stomach drop. You can see exactly how our fixed-price packages work.
This means we do the hard work upfront. Before we quote a price, we need to understand your problem properly. We ask questions. We dig into your workflow. We figure out what you actually need — not just what you think you need. That conversation is free, and it's the most important part of the process.
Once we've agreed on scope and price, our incentives flip. Now we're motivated to work efficiently, because the faster and smarter we work, the better the project is for us. We're incentivised to find the simplest solution, to avoid unnecessary complexity, and to get it right first time. That's exactly what you want too.
This is the question everyone asks. "What if I change my mind? What if we discover something mid-project that changes the requirements?"
That's normal, and we plan for it. Fixed-price doesn't mean rigid. It means the baseline scope and cost are agreed. If something changes — and something always does — we discuss it. Sometimes a change is small enough to absorb. Sometimes it's a swap: you want to add X, so we drop Y, and the price stays the same. And sometimes it's genuinely new work that warrants a separate, clearly-priced addition.
The key difference is transparency. You always know what you're paying and what you're getting. There are no open-ended invoices and no ambiguity.
The best client relationships are long-term. We want to build your first tool, prove the value, and then build the next one. That only works if you trust us.
Fixed pricing builds trust because it puts skin in the game on both sides. We're accountable for delivering what we promised at the price we quoted. You're accountable for being clear about what you need. Neither side has an incentive to waste time or add unnecessary complexity.
It also removes the power imbalance. With hourly billing, the developer holds all the cards — they control the hours, they control the pace, and you're along for the ride. With fixed pricing, it's a partnership. We succeed when you succeed.
We'll be honest: there are situations where hourly billing is appropriate. Ongoing maintenance, ad-hoc consulting, and genuinely open-ended discovery work are hard to scope in advance. If you need someone to investigate a vague problem or provide advisory support, hourly can work.
But for building software — tools, portals, automations, apps — where there's a defined problem and a concrete deliverable? Fixed-price is better for everyone.
When you work with JMS Dev Lab, you get a clear proposal before any work starts. The price is the price. You can ask questions, give feedback, and be as involved as you want without worrying about a ticking clock. And when the project is done, you know exactly what you've spent.
No surprises. No bloated invoices. Just software that solves your problem at a price you agreed to.
