Software Development Agencies

Most work is billed time and materials: an hourly or weekly rate per person on the team. US based senior engineers typically bill 100 to 250 dollars per hour through an agency, while firms with offshore delivery teams and US project management commonly blend down to 40 to 90 dollars. Fixed price bids exist but only make sense when the scope is genuinely nailed down; on vague requirements, a fixed price quote just means the padding is hidden.

The typical engagement starts with a paid discovery phase, usually a few weeks, that produces specs, designs, and an estimate. Treat that as a cheap way to test the firm before committing to a six figure build. After launch, most agencies sell a monthly maintenance retainer covering bug fixes, dependency updates, and small features. Budget for it: software that nobody maintains decays, and a common rule of thumb puts annual upkeep at 15 to 25 percent of the original build cost.

AI coding assistants have genuinely changed the economics of this category. Boilerplate, tests, and routine features now take a fraction of the hours they did, so well run agencies deliver more per billed week, and buyers increasingly know it. That is compressing prices for commodity builds while raising the premium on the judgment work AI does not do: architecture, integration with messy legacy systems, security, and knowing what not to build. Expect smaller teams on the same scope than you would have seen a few years ago, and be suspicious of any firm still staffing armies of juniors.

The other shift is the collapse of the pure body shop. Buyers burned by offshore teams with no product judgment are consolidating toward firms that take outcome responsibility: fewer people, closer to the business problem, often on retainer as a fractional product team rather than a one time project vendor.
