Reading the invoice is not the same as clearing it

A specialist capture tool answers “what does this document say.” Accounts payable teams need an answer to a harder question: does what it says agree with what we expected, and if not, what do we do about it.

That question spans systems. It needs the purchase order, the receipt, the agreed rate card, and the rules your team applies when things are close but not equal. Parabola does the extraction and then that reconciliation in the same Flow, with every step showing its input, logic, and output.

Which one is right for your team

Choose Rossum when high-accuracy invoice capture with a review workflow is the requirement, and downstream systems already handle the rest.

Choose Parabola when the recurring job is the whole cycle — read it, match it, apply the rules, and hand someone the exceptions.

Parabola vs. Rossum FAQ

Does Parabola do document extraction like Rossum?
+

Parabola's AI import steps extract data from PDFs, emails, and other messy sources. The difference is that extraction is one step of a Flow that also reconciles the extracted data against other systems, applies your rules, and produces the output — rather than the whole product.

When is Rossum the better choice?
+

When you have a single high-volume document type and extraction accuracy on that document is the thing you are optimising. A specialist tool tuned to one document class can be very strong at it.

What happens after extraction?
+

That is usually the larger problem. Extracted values still have to be matched against a purchase order or an ERP record, checked against business rules, and routed somewhere when they do not agree. Parabola handles extraction and everything downstream in the same Flow.
