I gave an example in the post above.
Recognising buyer names in suppliers' data feeds.
If done wrong - invoices generated for wrong customers, processed according to inappropriate rules in a wrong context, payments done by wrong organisations to wrong organisations.
Considering - big organisations (like universities) pay only once a month, - the financial penalties (fees and interest) would be significant, in our case they could easily exceed the service fee they paid to us.
And they would probably start looking for another service provider.
Is it damaging enough?
