## TL;DR

Rossum is built around understanding the document. Parabola is built around the process the document feeds.

- **Rossum's centre of gravity:** Capturing invoice data accurately, with a human review loop for corrections.
- **Parabola's:** The full recurring process — extract, reconcile against the ERP, apply rules, surface exceptions, produce the output.
- **Where Rossum genuinely wins:** Depth on invoice capture, including the review workflow around it.
- **Bottom line:** Pick Rossum if accurate invoice capture is the goal. Pick [Parabola](/) if capture is a means to a reconciled result.

## 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.

## Parabola vs. Rossum at a glance

| Dimension | Parabola | Rossum |
| --- | --- | --- |
| Document capture | AI import steps, as one step in a Flow | The specialism, with a review interface |
| Matching against POs, receipts, rate cards | Core capability across sources | Left to downstream systems |
| Business rules | Each step is generated for the logic you described | Out of scope |
| Exception queue | An Artifact can be the queue itself, with recommended actions | Correction of capture errors, not process exceptions |
| Breadth | Any recurring operational process, not only documents | Document-centred |

## 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.
