Invoicing
An invoice with a sequential number, your VAT ID and the right VAT wording, in your language or your client's. With a payment QR code and an e-invoice, reminders that go out by themselves — and every invoice lands straight in your VAT return.

With booxx you create Dutch sales invoices in five languages: the screen in your language, the invoice in your client's — Dutch, English, Polish, Hungarian or Romanian. Every invoice gets a sequential number, your VAT ID and the right VAT wording, including reverse charge and services to a business in another EU country, and goes out by email as a PDF with a payment QR code and the e-invoice (UBL) attached. Because it is complete accounting software, every invoice you send is immediately in your VAT return and your open items; after a 90-day free trial you pay € 19 a month, excluding VAT.
You work in your own language; your client gets the invoice in Dutch, English, Polish, Hungarian or Romanian. The language follows the preferred language on the client record and can be changed per invoice; the covering email goes out in the same language.
Pick the VAT code on each line and the required wording is added for you: reverse charge, intra-Community supply, export outside the EU, or exempt. If you use the small business scheme (KOR), the required KOR text is on every invoice. Without your client's VAT number, a reverse-charge invoice is not sent.
Your client scans the QR code with their banking app and gets a pre-filled transfer to your account — no payment provider in between and no extra fees. Not every banking app reads the code, so the IBAN, amount and reference are always printed in plain text as well.
The UBL file goes along with the PDF, so your client's accounting software can import the invoice. Sending through Peppol is in development.
Turn on automatic reminders and a reminder goes out 1, 8 and 15 days after the due date, in the language of the invoice and with the amount still outstanding in the payment QR code.
Rent, a subscription or a fixed monthly fee: you create it once. After that each instalment is waiting for you as a draft, or goes out by itself if you turn on automatic sending.
If you only want to send invoices and an accountant does the rest, you pay for more than you use with booxx: there is no separate invoicing plan, and no free plan after the trial. The benefit of one package shows when your VAT return is due. The invoices you send and the payments on your bank statement are already in the same books, and your accountant can access them at no extra cost.
Yes. The screen language is a setting per user, the invoice language a setting per client. You choose from Dutch, English, Polish, Hungarian and Romanian, and the email with the invoice goes out in the same language.
On an invoice to another business: your name and address and your client's, your VAT ID, your KvK number if you are registered with the KvK, a unique sequential invoice number, the invoice date and the date of supply, what you supplied and how much, and the amount excluding VAT, the VAT rate and the VAT amount. The full list with an example is in our guide to invoice requirements.
Yes. For a service to a business in another EU country you choose the VAT code for a service within the EU: the VAT is reverse-charged and the invoice says so ("Btw verlegd" on a Dutch invoice, "VAT reverse-charged" on an English one). On an invoice in Polish, Hungarian or Romanian, the English term "VAT reverse charge" is added in brackets. Your client's VAT number is required; without it the invoice is not sent.
If you signed up yourself, yes: you can send and download invoices once your KvK number, company name and postcode match the KvK. Name and postcode are taken from the KvK when you sign up, so usually you won't notice. Setting up and bookkeeping always work.
Invoicing is part of the Standard plan: € 19 a month per set of books, excluding VAT, with unlimited invoices. You start with 90 days free, without a payment method.
Not yet; that connection is in development. Until then the e-invoice goes along with the invoice email as a UBL file, so your client's accounting software can import it automatically.
