Accounts payable software for SMEs in Spain: when it pays off and what to check in 2026
Accounts payable software pays off for a Spanish SME when it receives many supplier invoices with purchase orders and delivery notes and the team can no longer match them line by line before paying. If it receives few invoices, or almost none carry an order, the ERP's purchasing module or an invoice reader is usually enough.
Signals that your SME needs it
| Situation | What fits |
|---|---|
| Few invoices a month, mostly fixed-amount services | Your ERP or accounting system with its invoice reader |
| Purchases against orders, goods with delivery notes, frequent partial deliveries | Software that matches invoice, order and delivery note line by line |
| Several companies sharing suppliers or mailbox | Assigning each invoice to its company by recipient tax ID (see assignment by company) |
| Invoices arriving twice | Duplicate blocking before approval |
What comparing totals misses
Constructed example: an SME orders 500 kg at €4.20/kg (€2,100.00 net). A delivery note for 300 kg arrives, then an invoice for 500 kg at €4.20/kg. Against the order, the invoice matches. Against the delivery note, €840.00 is invoiced for 200 kg not yet received.

Frequently asked questions
Doesn't my ERP already read received invoices?
Many accounting systems and ERPs read the invoice and propose the entry. What they rarely do is check each line against the purchase order and the delivery note. If you buy against orders, that check is what stops overpayment.
When will my SME have to receive e-invoices?
According to Spain's Tax Agency, companies with a turnover of up to 8 million euros must issue, send and receive e-invoices from 6 October 2028; legal entities must also report invoice status and payment.
Why is comparing the invoice with the purchase order not enough?
Because the order says what you asked for, not what arrived. If the supplier invoices the full order and the delivery note records a partial delivery, the invoice matches the order and still charges for goods you have not received. Only line-by-line matching against the delivery note catches it.
Does ininvoice approve invoices automatically?
No. ininvoice matches every line and prepares the decision, but approving, rejecting or asking the supplier for clarification is always done by a person, and it stays in the invoice history.
Is ininvoice for SMEs?
It suits mid-sized SMEs that receive many invoices with purchase orders and delivery notes. If you receive few invoices or almost none carry an order, your ERP module or an invoice reader is usually enough.
