"How much does custom software cost?" is the first question every business asks and the hardest to answer honestly, because it depends entirely on what you build. But you deserve better than "it depends." Here is what actually drives the price and how to think about it.
What drives the cost
Scope - by far the biggest factor
The number and complexity of things the software does is the dominant cost driver. A focused tool that does one job well costs a fraction of a sprawling platform. Most cost overruns come from scope, not hourly rates.
Integrations
Connecting to other systems - your accounting package, a payment processor, a legacy database - adds cost, especially if those systems are old or poorly documented. Each integration is its own small project.
Data complexity
Clean, simple data is cheap to work with. Messy, inconsistent, or scattered data needs cleaning and reconciliation before anything can be built on it - real work that is easy to underestimate.
Users and permissions
Software one person uses is simpler than software with many roles, permission levels, and audit requirements.
Ways to spend less
- Start with the smallest useful version. Build the one thing that delivers value, put it to use, then expand based on what you learn. Half the features on most "requirements" lists turn out not to matter.
- Connect instead of rebuild. A small layer that ties together tools you already own is far cheaper than replacing them.
- Clean your data first. If it is a mess, tidying it up front prevents expensive surprises later.
- Be honest about what is core. Pay for the part that differentiates you; buy the commodities.
Ongoing costs to plan for
Software is not a one-time purchase. Budget for hosting and infrastructure, occasional maintenance and updates, and future changes as your needs evolve. These are usually modest relative to the build, but they are real - plan for them so nothing is a surprise.
How we quote
We start with the problem, not a feature list - because the goal is the cheapest thing that solves it, not the biggest thing we can build. We scope a focused first step, explain the tradeoffs, and agree on what success looks like before writing code. You see working progress early, in usable pieces, so cost tracks value rather than disappearing into a year-long project. Read more about how we build software.
The most useful number is the one for your specific problem. Describe what you need and we will scope it honestly - including telling you when off-the-shelf would be the cheaper answer.
