Invoice

Use the reference your buyer requires, such as a Leitweg-ID for a German public-sector recipient.

From (seller)

Two letters, for example DE, FR or NL.

XRechnung needs the seller's contact name and telephone.

XRechnung needs the seller's contact name and telephone.

The seller's electronic address, with its scheme, for example an email address or Peppol ID.

The register the address belongs to. Klarbon suggests one from the country and the address, and you can change it.

For example a SIREN in France, a KVK number in the Netherlands or an enterprise number in Belgium.

To (buyer)

Two letters, for example DE, FR or NL.

The buyer's electronic address, for example a Peppol ID. Enter a Leitweg-ID in Buyer reference if your public-sector recipient requires one.

In short

Fill in one form and get an e-invoice checked against the selected rules, for the few you send a year. Free preview, then 1 credit (€4.99).

Klarbon's Make tool creates a single e-invoice from a form: enter your details, your customer's, the lines and the payment terms, choose the format, and download a file that has passed validation. It writes XRechnung, ZUGFeRD, Factur-X, Peppol BIS, UBL and CII, for one credit per invoice. It is for occasional invoices, not a replacement for invoicing software.

How do I create an e-invoice?

  1. Choose the format your customer asks for. If a field the format requires is missing, the check says so before you pay.
  2. Enter the seller and buyer: names, addresses, VAT numbers and, where needed, the buyer reference or Leitweg-ID.
  3. Add the lines: description, quantity, unit, price and VAT rate. Klarbon calculates the totals.
  4. Add the payment details: due date, IBAN and any payment reference.
  5. Validate and download. Klarbon writes the file and checks it against EN 16931 and the format's rules. The preview is free; one credit unlocks the download.

Which format should I choose?

What the recipient requests Format
XRechnung for a German public-sector portal XRechnung, with its required buyer reference
A hybrid PDF for a German business ZUGFeRD, in the profile it accepts
Factur-X through a French business's approved platform Factur-X
Peppol BIS Billing through an access point Peppol BIS Billing
UBL in a specification they name UBL, if that specification is supported

ZUGFeRD and Factur-X are PDFs with the XML inside, readable by people and software. XRechnung, Peppol BIS and UBL are XML files, read by software or a viewer.

Who is this for?

People who send a few e-invoices a year: a freelancer with one public-sector customer, a club that invoices a municipality, a small business whose largest customer now asks for e-invoices. If you send invoices every week, invoicing or accounting software that writes e-invoices saves you typing.

What does Klarbon not do?

Klarbon keeps no customer list, no invoice numbering and no archive. You choose the invoice number, follow your own numbering, and keep the downloaded file as long as your tax rules require. Klarbon does not send the invoice and does not give tax advice on VAT treatment; ask your tax adviser if you are unsure which VAT rate or exemption applies.

What happens to the data I enter?

It is processed on Klarbon's servers to write and validate the file, then deleted. See what happens to my files.

What does it cost?

One credit per invoice: EUR 4.99 including VAT, or less in packs of ten or fifty. Filling the form and the validated preview are free. A new account includes one welcome credit. See prices.

Frequently asked questions

How can I create an e-invoice without accounting software?

Fill in Klarbon's invoice form, choose the format your customer asks for, and download the file once it has passed validation. It costs one credit per invoice and needs no software or subscription.

Which formats can I create?

XRechnung, ZUGFeRD, Factur-X, Peppol BIS Billing, UBL and CII.

Does Klarbon keep my customers or invoice numbers?

No. Klarbon is not invoicing software. It keeps no customer list, no invoice numbering and no archive, so you choose the invoice number and keep the file yourself.

Who is this for?

People who send a handful of e-invoices a year, such as a freelancer with one public-sector customer. If you invoice every week, invoicing software that writes e-invoices will suit you better.

Does the created invoice get sent?

No. You download it and send it the way your customer asks, by email, through their portal or through a Peppol provider.
