Don't buy a quality system.
Start with one workflow.
Most eQMS projects begin with a nine-month selection and end with a system that holds the same gaps the old one did. The Sprint runs the other way round. Ten working days, one real process of yours, and a written answer at the end - including the answer that says not yet.
Workflow
your real one, running as it runs today
Working days
fixed scope, fixed price
Obligation
to buy anything at the end of it
