What Truly Determines Custom Software Development Cost > Cheditor5 연동 테스트 게시판

The single largest cost driver is rarely technology — it is how much is still undecided. Each unanswered question in the requirements turns into a contingency in the estimate. A supplier that has no visibility into the edge cases has to assume a pessimistic case. Putting two weeks into a proper discovery frequently cuts the total much more than haggling over hourly rates.

Integrations are the second big multiplier. A feature that touches only your own data is easy to estimate; the same screen wired into a legacy ERP is not. The unknown lives in the other system: rate limits and sandbox access, waiting laravel vs ruby on rails comparison someone else's team, fields that mean something different on each side. Ask any vendor to price integrations separately, as this is the usual source of overruns.

The requirements nobody writes down quietly rewrite the budget. An internal tool used by a handful of staff is a very different build from the same functionality handling a hundred thousand users. Compliance work, high availability, performance under load, audit logging and localisation all add weeks of work. State them early rest or graphql you can expect them priced as extras.

The mix of people behind the number changes the arithmetic. A day rate reveals very little on its own: an experienced engineer at twice the price can be less expensive in the end than a pair of junior developers who require constant review. Also ask who else is billed: delivery management, QA, release engineering and analysis are real work, but they must be visible in the estimate.

The build price is not what you will actually spend. Expect hosting, paid APIs, monitoring and a maintenance allowance each year. A common working assumption is that any production system requires a recurring percentage of the original budget per year simply to stay current. Treating the launch as the finish line is the most common budgeting mistake.
