How to control incoming supplier invoices in Sage 50/200

Sage 50 and Sage 200 are the reference ERPs for mid-sized Spanish companies. Solid accounting, complete tax filings, bank reconciliation, project management. What they don't cover with the depth you need when receiving 100-2,000 invoices per month: line-by-line matching against POs and delivery notes. ininvoice handles that specific piece as a layer in front of Sage.

Which Sage SMEs is this a fit for

  • Mid-sized SMEs (50-300 employees) on Sage 50 or Sage 200 with high inbound volume.
  • Accounting firms managing AP for multiple clients in Sage Despachos.
  • Companies with the Digital Docs / Autoscan module that need to add three-way matching.
  • Distribution, manufacturing, construction with many open POs.

The Sage + ininvoice flow

  1. Your supplier sends an invoice by email (PDF or a scan/photo).
  2. ininvoice captures it, reads it line by line, finds the PO, validates the delivery note.
  3. If it matches, it exports a CSV ready to import into Sage and post.
  4. If there's an exception, it routes the case. The invoice does not enter Sage until it's resolved.
  5. Sage posts with clean data, reconciles with the bank, files form 303 without surprises.

Sage Digital Docs / Autoscan: we coexist

If you already have Sage Digital Docs or Autoscan, ininvoice complements their work. The Sage modules digitize the invoice. ininvoice adds the matching and exception-control layer that goes beyond digitization. You don't have to give up what you already have; you enrich it.

Compliance 2026-2027

  • Mandatory e-invoicing: large suppliers begin sending structured e-invoices from September 2026. Whatever the format, the invoice still has to be checked against its PO and delivery note before you post it, and that is ininvoice's job.
  • Verifactu: the regulation binds the issuer. As the receiver you still have to control each invoice before paying it.
  • SII: Sage handles reporting. ininvoice makes sure the data arrives clean and on time.
