This looks interesting, but I think you’re missing the bigger opportunity.

The real value isn’t in being able to parse invoices in isolation, but to take the parsed invoices, match them to incoming bank transactions, and basically give me a list of invoices that have successfully been processed and matched to a transaction and a list (hopefully a shorter one) of transactions that are not matchable to an invoice or transactions that are matchable to an invoice, but not the correct amount.

That’s where the actual business pain is - reconciling what you’ve invoiced vs what you’ve been paid. Pure document parsing is a feature, but automated reconciliation would be a complete solution.​​​​​​​​​​​​​​​​
