As a consultant, I used to ask my clients to QA my deliveries. Few of them were willing to, to the extent they did they could not or would not provide meaningful bug reports.
This led to my adoption of test-driven development - mostly but not all automated testing - with the eventual result that I advertised that my final deliverables would be ready to ship to end-users, without any requirement for QA by my clients.
