The honest answer: it depends — but 'it depends' isn't useful. Here's what actually drives cost, real ranges, and how to budget intelligently.
What actually drives the cost
Software cost is roughly: scope × complexity × team rate × time. Scope is what it does; complexity is how hard that is (integrations, permissions, real-time data, compliance); rate depends on who's building it and where; time follows from the first two.
The biggest cost driver isn't technology — it's ambiguity. Projects where requirements change weekly cost multiples of projects with a stable, well-understood scope. Money spent on discovery is usually the highest-ROI money in the budget.
Realistic ranges by project type
Broad ranges, assuming professional senior teams: a marketing website, $3k–$15k. A customer portal or internal tool, $15k–$60k. A SaaS MVP, $30k–$120k. A substantial multi-system platform, $100k and up, usually phased.
These ranges overlap because complexity matters more than category. A 'simple website' with a booking engine, payments and CRM integration is not a simple website.
Why the cheapest quote is often the most expensive
A quote 50% below others usually means one of three things: junior staffing, misunderstood scope, or a plan to bill change requests later. All three end in the same place — a rebuild, a rescue engagement or a abandoned codebase.
Compare quotes on what's included: discovery, design, testing, deployment, documentation, handover, warranty period. A cheaper number covering less is not cheaper.
How to budget intelligently
Phase your investment. Fund a paid discovery to produce a proper scope and estimate. Build the smallest version that delivers value, measure, then fund the next phase with evidence. This turns one large risky bet into several small informed ones.
Also budget for after launch: maintenance, hosting, and improvement typically run 15–25% of build cost annually. Software that isn't maintained becomes a liability surprisingly quickly.
