Guide
A GmbH/Sàrl invoices in its own name, not in the names of its shareholders. In practice, this affects three things: the legal name shown on the document, the identification details business customers expect, and disciplined filing for the year-end close.
The invoice should use the name entered in the register, including the legal form, not an approximate trading name. If the customer's accounts team cannot identify the exact entity, the invoice may be returned or payment delayed.
The address shown is the registered office. If you work elsewhere, a correspondence address can be added, but it does not replace the registered office.
A registered GmbH/Sàrl has a UID number. Showing it on the invoice avoids follow-up requests from customers who need to create your supplier record.
When the company is VAT liable, the same number with the VAT designation is expected on the document.
VAT liability for a GmbH/Sàrl depends in particular on turnover and the nature of the services, not on the legal form itself. A young company may therefore invoice without VAT for a period and become liable later.
From the date VAT liability starts, the applicable rate and amount appear on subsequent invoices by line and rate. The Federal Tax Administration publishes the current rules and rates.
You can try a complete invoice right now, without an account.
Try the generatorA company prepares annual accounts. Invoice numbering should therefore remain continuous across the financial year, with no gaps or duplicates, even when several people issue invoices.
The key issue is not one invoice in isolation but the full set: numbers, amounts and dates should match between documents sent to customers and those handed to the fiduciary.
Payments should go to the company's bank account, never a private account. The payment section with QR code includes these details, the amount and reference, making incoming payments easier to reconcile.
With a QR-IBAN and structured reference, each incoming payment can be matched unambiguously to a specific invoice. This becomes useful even with only a few dozen invoices per year.
Most fiduciaries need two things: the issued documents and a table listing invoices, amounts, dates, statuses and applied rates. A tabular export covers this need without requiring a full accounting package.
Monthly filing takes a few minutes, reconstructing a full year can take a day. The difference is simply regularity.
