Something I dealt with a lot in oil & gas engineering, and have never personally witnessed in software engineering, is a "change order".
This is commonplace in custom software development in my experience. Having a change control process in place, and negotiating a price-tag for changes to the original contract, happened all the time in my first programming job. We were mainly working for government agencies (municipal and county government), universities, etc., and this was all completely normal.
