Dealing on larger projects and mediating between my PHP development team and the Client is often a far simpler task than acting as a sole freelancer. Having a very good and reliable team of 12 long term offshore PHP programmers, means that I now have sufficient confidence that I could theoretically just pass their overall estimates straight on to the Client without issue. Even still, I add at least 10% to the PHP developer’s estimates as well as subtracting at least 10% from the Client’s final delivery date. If we’re all happy and can agree on those deadlines, great. This allows for a comfort period for us, as well as the ability to iron out bugs and perform good QA on anything delivered.
