From source documents to an approved import file.
Define the output before extraction
List invoice number, supplier, date, currency, subtotal, tax, total, and any required line items. Specify how missing values and credit notes should appear.
Choose a representative batch
Include clear and difficult layouts, multiple currencies if relevant, and a multi-page invoice. Keep a source filename or document ID with every row.
Extract to a review destination
For the spreadsheet route, configure the invoice parser in Parsio and export to CSV, Excel, or Google Sheets. Keep the first handoff manual until field mapping is checked.
Resolve exceptions against the original
Compare identifiers, currency, decimal separators, totals, and line-item sums. Mark uncertain values for review rather than filling them from context. Check duplicates against your own received-document list.
Import a checked batch
Export only reviewed records in the required format. Confirm a small import and reconcile the record count and total before processing the remaining batch. Payment approval stays separate.
Specify the extraction and review rules.
Use this as an extraction specification and review sheet; map fields to the chosen tool manually.
BATCH
Source folder: [location]
Destination: [CSV, spreadsheet, accounting import]
REQUIRED FIELDS
Document ID, source filename, supplier, invoice number, issue date, due date, currency, subtotal, tax, total, line items

Preserve printed values. Leave unreadable fields blank and flag them.
Keep credit notes separate. Do not infer currency from a symbol alone.
Retain the original document link.

Questions before you start.
Can I let the tool pay the invoices?
This workflow ends with reviewed records. Keep payment authorization in your established process, with explicit checks for the supplier and payment destination.
Should I choose an API or a spreadsheet tool?
Choose an API when your team will build and maintain the review and integration steps. A spreadsheet export is easier to inspect when the immediate goal is a small checked batch.
Why do page and document prices differ?
Providers meter different units. A long invoice may cost several page credits, one document transaction, or multiple workflow steps. Estimate with your actual page counts and chosen actions.
Does a confidence score replace review?
Use it to prioritize review. Check required fields and exceptions against the original, especially identifiers, currencies, totals, and any details used by the next system.
