The dominant factor is rarely the choice of framework — it remains unclear scope. Each unanswered question in the specification turns into a contingency in the estimate. A vendor that does not know the edge cases has to assume the worst. Investing a few days in a proper discovery can cut the overall figure by far more than any rate negotiation.
Third-party integrations are the next major multiplier. A feature that touches only your own data is low risk; the same functionality wired into a payment provider and a CRM is a different problem. The effort lives in the other system: undocumented APIs, slow approval cycles, fields that mean something different on each side. Ask the estimator to list every external system, as this is where estimates break.
Non-functional requirements can easily double the estimate. A tool used by a handful of staff is a very different build from the same feature set serving public traffic. Security reviews, availability guarantees, performance under load, traceability and localisation all add weeks of work. Put them in the brief or expect the estimate to move later.
Who actually does the work matters a great deal. A rate card reveals almost nothing on its own: an experienced engineer at twice the price can be cheaper per delivered feature than two inexperienced developers who need constant review. Check too what else appears on the invoice: delivery management, QA, it consulting services DevOps and UX design are real work, but these should be named rather than hidden inside a blended rate.
The build price is not what you will actually spend. Plan for infrastructure, third-party licences, observability and an ongoing support budget each year. A common working assumption is that software development companies in uk in active use consumes a recurring percentage of the original budget annually for updates, security patches and small improvements. Leaving it out of the budget remains the classic mistake.
