Software to manage the invoices you receive from your suppliers

The problem your accounting ERP does not solve

If your SME receives between 100 and 2,000 supplier invoices per month, you face invisible work: someone has to receive each invoice, open it, check it against the purchase order, against the delivery note, flag discrepancies, log duplicates, talk to the supplier, decide whether to pay, post and archive. That is hours every day.

Holded, Quipu, Anfix and similar products record the invoice. They post it as an expense. But the control work (is this the price I agreed? is this the quantity I received? is this a duplicate?) is still done by a person in Excel.

This is where ininvoice fits. It does not replace your accounting. It is the layer that lives before: it receives the invoice, validates it, cross-checks it, routes it and then hands it over to your ERP already validated.

Who this software is for

It is for you if...

• You receive between 100 and 2,000 supplier invoices per month.
• Most of your suppliers are Spanish (some occasional intra-EU casuistry is acceptable).
• Your ERP is Holded, Sage 50/200, A3, Contasol, Quipu, or you coexist with Excel + an external accounting firm.
• You process purchase orders and receive delivery notes (industry, distribution, hospitality, construction, retail).
• You have detected at least once a month an overpayment or a duplicate by mistake.

It is NOT for you if...

• You process fewer than 50 invoices per month: the savings do not pay off.
• You are a multinational with complex multi-currency payments: Tipalti or Coupa are a better fit.
• Your business is pure B2C and you do not receive significant supplier invoices.

What a received-invoice software solves

Five categories of concrete problems that show up every day:

1. Capture without manual work

Invoices arrive by email, by supplier portal, by WhatsApp, by scanned paper. Your system has to accept them and normalize them. ininvoice connects to Gmail by OAuth and captures invoices automatically; documents from other channels can be uploaded manually.

2. Line-by-line extraction

Reading the header (supplier, date, total) is not enough. You need the individual lines: description, quantity, unit price, discount. Without lines you cannot reconcile against the purchase order. Here we explain how line-by-line OCR works.

3. Three-way matching

Cross-checking the invoice with the purchase order and with the delivery note line by line, pre-tax. It is the only way to detect overpayments that header-total matching hides. Full guide here.

4. Duplicate detection

The same invoice number arriving twice. The same invoice with minimal variation. The same supplier sending both. Multi-criteria detection (supplier + number + date + amount + hash) that prevents paying twice.

5. Exception routing

When something does not match, who fixes it? Price discrepancy to purchasing. Quantity to the warehouse. Duplicate to automatic block. Invoice without a PO to manual review. Having this routing explicit prevents exceptions dying in a finance inbox.

Received-invoice software vs accounting ERP

Capability	ERP / Accounting (Holded, Quipu, Sage)	ininvoice
Invoice issuance	Yes, core function	No
Email reception and capture	Limited or requires extra module	Yes, native
Template-free OCR	Variable	Yes, IDP
Line-by-line three-way matching	Not standard	Yes, product core
Multi-criteria duplicate detection	Basic	Yes
Tax validation (total = base + VAT − IRPF)	No	Yes, before matching
Exception routing	No	Yes, by type
General ledger posting	Yes, core function	No (Excel/CSV export)
Bank reconciliation	Yes	No
Tax filings (303, 390, 347)	Yes	No

The conclusion: they are not competitors. They are complementary. Your ERP remains the place where postings and filings happen. ininvoice is the control layer that feeds it with already-validated invoices.

Use case: distributor with 600 invoices/month

SME distributor, 80 active suppliers, Holded ERP. Before ininvoice, one person spent half a day matching invoices against orders in Excel.

Estimates for an average SME distributor profile:

• Manual matching time: about 80 h/month, on the order of 1,200 EUR/month in internal hours.
• Discrepancies detected manually: about 6% of invoices with variance above threshold.
• Discrepancies detected with line-by-line matching: about 9-11%; header-total matching does not see compensations between lines.
• Overpayments identified in the first quarter: four-figure range, enough to pay back the annual cost.

The sales argument is not "automate to save hours". It is "detect what header-total matching hides".

Regulatory compliance 2026-2027

Three regulations directly affect the invoices you will receive from your suppliers:

• Mandatory B2B electronic invoicing (RD 238/2026): starting September 2026, large suppliers begin sending you structured XML. Full guide here.
• Verifactu (RD 1007/2023): starting 2027, invoices you receive come with QR + AEAT hash. Guide here.
• SII: if your company exceeds thresholds, report to AEAT within 4 days of recording.

ininvoice is built around these three. They are not extra modules: they are the design context.

Frequently asked questions

Does ininvoice replace my accounting ERP?

No. It coexists with your ERP (Holded, Sage, A3, Contasol, Quipu). ininvoice is the control layer that validates invoices before they enter your ERP.

Does it work with any billing provider?

It works with the PDF and image invoices your suppliers send, regardless of which software they use to issue them. It does not parse structured FacturaE, Factur-X or UBL XML today; if a supplier sends a structured e-invoice, you process its human-readable PDF.

What do I need to get started?

Access to the Gmail account where you receive invoices, export of your active purchase orders in CSV, and half an hour from the person who validates invoices today.

Does it modify anything in my email?

No. The connection uses OAuth. It does not send, modify or delete email.

Is there a commitment?

No. Monthly plan, cancel with one-month notice. No annual minimums, no setup fee.
