Frequently asked questions

Invoices

Can I still change a finalised invoice?

No. A finalised invoice is locked, as the Belastingdienst requires. Create a credit note and then a new invoice if needed. As long as an invoice is a draft, you can change everything.

Why doesn't my draft have a number yet?

An invoice only gets a number when you finalise it. That way there are no gaps in your numbering when you throw a draft away. See Invoice numbering.

Can I continue the numbering from another program?

Yes. Under Settings → Invoices & numbering, set the format you're used to and set the Next sequence number to the number after your last invoice. See Invoice numbering.

How do I get invoices to my accountant?

Download the PDF and UBL per invoice, or with Pro make a ZIP export with all PDFs, UBL files and a CSV overview. Almost any accounting package can import the UBL.

Can I invoice in English, German or French?

Yes. Choose the Invoice language per invoice or set it per customer. All fixed texts, including the legal VAT statements, then use that language.

Can I invoice in another currency?

Yes. With VAT, the VAT amount must also be on the invoice in euros; we fetch the ECB rate for that. See Currencies and exchange rates.

Does EenFactuurMaken.nl see when an invoice has been paid?

No, we're not connected to your bank. Mark an invoice as paid yourself, or do it automatically through the API. You can see whether your customer has viewed the online invoice.

VAT

Which VAT treatment should I choose?

See Choosing a VAT treatment. In short: Dutch customer standard VAT, construction subcontracting reverse charge, business in the EU "EU customer", customer outside the EU "Customer outside the EU", and KOR or exempt if that applies to you.

I use the KOR. Do I still need a VAT number on the invoice?

No. A KOR invoice doesn't mention VAT anywhere, not even a VAT number. See KOR.

Can EenFactuurMaken.nl file my VAT return?

No, but the VAT overview prepares your turnover and VAT per box. You add your input VAT yourself.

Plans and payment

What counts towards my 5 free invoices?

Every invoice you create, including duplicates and drafts. Credit notes don't count, and you get a deleted draft back. See Free and Pro.

What happens to my invoices after 60 days on the Free plan?

We delete them, after two email warnings. So download them. With Pro we keep them for 7 years. See Storage and retention.

Can I cancel Pro monthly?

Yes. You keep Pro until the end of the paid period. See Upgrading and cancelling.

Do I get an invoice for my subscription?

Yes, for every payment, by email and to download under Settings → Subscription.

Data and security

Where is my data stored?

On Hetzner servers in Germany. Email goes through Resend (sent from Ireland). See Privacy and hosting.

Can I create an invoice without an account?

Yes, with the free invoice generator. Nothing is stored on our servers.

I lost the phone with my authenticator app.

Sign in with one of your backup codes, or have a code sent to your email. Then set up 2FA again with your new phone. See 2FA and passkeys.

Integrations

Do the API or the MCP server cost extra?

No, they're included in every plan, including Free. Your plan's limits do apply.

Can my AI assistant just send invoices?

Your assistant always creates a draft first. Finalising and sending are marked actions; most AI apps ask for your permission first. See MCP server.

Do you send e-invoices through Peppol?

We create e-invoices in the Peppol format (UBL, NLCIUS) and attach them to your email, but we don't send through the Peppol network ourselves (yet). See PDF and e-invoice.
