Reviewing "match fails" between purchase orders & invoices.

Ezzybills is software that we are rolling out to automate the matching & receipting of invoices to purchase orders that have been raised.

I'd like to retain a few hours a day (+- 3-4 ) over the next few weeks to ensure that our "failed" invoices are not going to cause problems;
- by categorising the nature of the errors;
- and resolving the errors;
- whilst at the same time documenting the work-flow, so that in 2-3 weeks, the process can be handed on to our normal payables team members;
- once the initial bulk "fails" have been resolved.
