Invoice issuers

The Master data page (/en/account/master-data). One account can keep several invoice issuers — for service providers who invoice “in the name and for the account of” several clients.

What is stored per invoice issuer

Group	Content
Label	for selection within the account only; does not appear on the invoice; unique per tenant
Seller	name, VAT ID, registration or tax number, address, contact person, telephone, email
Payment	payment method, IBAN, BIC, account holder, bank, payment terms, currency
FatturaPA	the public-administration flag, recipient code, PEC address
Logo	PNG or JPEG, no larger than 1 MB

Deliberately, only what belongs to the invoice issuer is stored: line items, buyer and dates are discarded on saving.

For XRechnung, contact person, telephone and email are mandatory

All three are carried into every generated invoice — including from bulk import. Enter them here and you never need to enter them again.

Prefilling and selection

Exactly one profile carries the star ★ and prefills the create form. If an account has no profile at all, the first click on Save master data creates one. That profile’s logo is used automatically on generated invoices, as long as no other is uploaded during creation.

A profile identifier passed in from outside — a form field or sellerProfileId through the API — is always resolved against your own tenant; if it does not belong to it, the prefilled default applies instead. An identifier belonging to someone else is therefore ineffective, not dangerous.

The number-range trap

Invoice issuers and number ranges are connected, but not automatically:

How it came about	Number range
The first invoice issuer of the account (via Save master data)	none of its own — it counts along in the shared tenant range
Every further one via Add another invoice issuer	immediately gets its own range, using the tenant’s pattern as a starting point

This is deliberate: an existing account should carry on its running number sequence unbroken when it creates an invoice issuer for the first time.

Two consequences you need to know

A profile without its own configuration counts along in the tenant range. Two such profiles therefore draw alternately from the same sequence. Anyone who needs a separate gap-free sequence per client gives the profile its own range explicitly on the Number range page.

Deleted invoice issuers do not release their counters. Deleting removes the master data, the logo and the numbering configuration — the counter values already drawn remain. A number issued under section 14 of the German VAT Act must not be reissued just because someone deleted an invoice issuer and created a new one.

Archived invoices are unaffected by any of this anyway; they carry their own copy of the data.

If the invoice issuer marked as the default is deleted, another one takes its place automatically so that the create form stays prefilled.

Where to go next

Number ranges describes how a range of its own comes about and what the two uniqueness guards do.
