Holded is the ERP most widely used by digital Spanish SMEs. It does its job well: accounting, billing, bank reconciliation, tax filings. But controlling the invoices you receive (line-by-line matching against POs and delivery notes) is not its focus. That's what ininvoice covers. We coexist. We don't replace.

The natural split: Holded books, ininvoice validates

Task	Holded	ininvoice
Receive supplier invoice from email	Manual / extra module	Automatic (Gmail)
Extract invoice line items	Basic OCR	Line-by-line OCR/IDP, no templates
Match against purchase order	Header total comparison	Line by line, pre-tax
Match against delivery note	Not automated	Yes, partial receipts included
Duplicate detection	By invoice number	Multi-criteria (supplier + number + date + amount + hash)
Tax validation (VAT / IRPF / tax ID)	No	Yes, with explicit block reasons
Hold exceptions with their reason	No	Yes: price, quantity or duplicate, for a person to decide
Post invoice to the general ledger	Yes, core feature	No
Bank reconciliation	Yes	No
Tax filings (303, 390, 347)	Yes	No
Issue customer invoices	Yes	No

What you see: neither tool steps on the other. Holded stays your ERP. ininvoice adds the missing layer before the invoice enters Holded.

Why Holded doesn't do line-by-line matching

It's not a Holded shortcoming. It's a product decision. ERPs and accounting software are designed for an SME that already has the invoice validated by the time it reaches the system. They assume someone has already reconciled it. That's why they compare totals, not line items.

For an SME with 30 invoices/month that model works: someone reviews them by hand, balances them in a spreadsheet, then enters them into Holded. For an SME with 600 invoices/month the model collapses: nobody has time to review every document line by line, and invisible overpayments pile up.

Detail on how overpayments slip through when you only reconcile header totals: The total-matching trap.

The combined Holded + ininvoice flow

Your supplier sends an invoice by email (PDF or a scan/photo).
ininvoice pulls it from email, reads it line by line, finds the PO, validates the delivery note.
If everything matches and a person approves it, ininvoice exports a CSV ready to import into Holded for posting.
If there's an exception (price, quantity, duplicate), it holds the invoice with the reason visible. The invoice does not enter Holded until a person resolves it.
Holded posts the invoice with clean data, reconciles it with the bank on payment, and feeds your tax filings without surprises.

Which Holded SMEs is this a fit for

SMEs receiving 100-2,000 supplier invoices per month.
Businesses with many open POs: distribution, multi-location hospitality, retail, light manufacturing, construction.
Small back-office teams that drown at month-end close.
Companies that have caught at least one overpayment or duplicate per month and know it's the tip of the iceberg.

Where it's NOT a fit

SMEs with fewer than 50 invoices per month: the time savings don't pay off.
Pure B2C businesses with no meaningful supplier base.
Companies that don't work with structured purchase orders (one-off purchases without a documented PO).

How it connects to Holded today

Transparently: ininvoice exports the bills a person has approved as a CSV that imports directly into Holded. Your accounting team imports the batch into Holded in 5-10 minutes at end of day.

Native API integration with Holded is on our roadmap. In the meantime, the CSV flow handles daily operations with no friction and no in-house IT dependency. If your SME needs a more automated flow, we can scope it together up front.

Verifactu, e-invoicing and SII compliance

The regulations rolling out in 2027 and 2028 affect both Holded and the inbound flow:

Mandatory e-invoicing: suppliers start sending structured e-invoices instead of PDF from 6 October 2027 for companies with turnover above EUR 8 million and from 6 October 2028 for everyone else (AEAT calendar). Whatever the format the invoice arrives in, it still has to be controlled against its PO and delivery note before it enters Holded, and that is the layer ininvoice adds.
Verifactu on the receiving side: 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) the invoices you receive start carrying a QR code. The regulation mainly binds the issuer; on your side the job stays the same, control each invoice before you pay it.
SII: Holded handles reporting. ininvoice helps deliver clean data, fast.
