How to control incoming supplier invoices in Quipu
Quipu handles the accounting of many Spanish SMEs and self-employed professionals. It does its job well: issuing, expenses, tax filings, reconciliation. What's not its focus: line-by-line control of the supplier invoices you receive. When Quipu alone isn't enough, and how ininvoice fits as a layer in front.

When Quipu alone is enough and when it isn't
Quipu alone is enough when:
- You process fewer than 50 supplier invoices per month.
- Your back office has time to review every invoice by hand.
- Your suppliers are few and consistent (predictable purchasing).
Quipu falls short when:
- You receive 100+ invoices/month from 30+ different suppliers.
- You work with purchase orders and delivery notes (industry, distribution, hospitality, retail, construction).
- You've caught at least one overpayment or duplicate per month.
- You're subject to the SII (Royal Decree 596/2016) and need to send invoice records to the AEAT within four days, not counting Saturdays, Sundays or national holidays.
The Quipu + ininvoice flow
- Your supplier sends an invoice by email.
- ininvoice captures, reads line by line, finds the PO, validates the delivery note.
- If it matches and a person approves it, it exports a CSV ready to import into Quipu and post.
- If there's an exception (price, quantity, duplicate), it holds the invoice with the reason visible. The invoice does not enter Quipu until a person resolves it.
- Quipu posts the expense, reconciles it with the bank on payment, and feeds form 303.

- Verifactu on the receiving side: invoices with a QR code during 2027 (RD 1007/2023, as amended by RDL 15/2025: before 1 January 2027 for corporate income tax payers and before 1 July 2027 for everyone else; the Ministry of Finance has announced a delay to October 2028 that is not yet in the BOE).
- SII: Quipu handles reporting when it applies. ininvoice accelerates clean data delivery.
