The effort hides in the third party: poor documentation, slow approval cycles, data that does not match your model. Ask each bidder to price integrations separately, since this is the usual source of overruns. Non-functional requirements silently change the number. An internal tool used by a small internal team has almost nothing in common with the same feature set serving public traffic. Security reviews, uptime targets, performance under load, data retention rules and multi-language support each add weeks of work. State them early or you can expect them priced as extras. The team you are quoted matters. A rate card reveals almost nothing on its own: a senior engineer at a higher rate can be cheaper per delivered feature than a pair of junior developers who need heavy code review. Ask as well which roles are billed: project management, quality assurance, release engineering and analysis have to be done by someone, but these should be itemised. The number in the proposal is not the total cost.
