Month-end close stops being three days of matching delivery notes against invoices.

The day’s signed delivery notes go into the invoicing queue on their own, grouped the way each customer asks for: daily, weekly or monthly. What you review in the morning is what was left out, not what is already done.

Sample figures from a typical distributor. Yours come out of the diagnostic.

02The chain

Every invoice signs the one before it.

It isn’t a stamp you add at the end: it’s the fingerprint of the previous invoice built into the next one.

Remove one from the middle and the chain breaks — which is why you cannot.

Sample numbers and fingerprints. Your real chain starts with the first invoice you issue in Larstel.
03Invoicing rules

Invoicing rules differ from country to country.

Larstel keeps signed, unalterable invoice records and files what your tax authority asks for, and keeping that up to date is part of the licence, not a module we invoice when a deadline gets close. What applies to you is something we go through in the diagnostic.

Your accountant keeps their software

You send them the month reconciled. You don’t ask them to switch.

04Questions

What people ask us before they sign.

01What if the rules change?+

Keeping up is part of the licence: when the regulation changes we update the system and tell you, on one page, what changes in your day.

02Can my accountant keep their own software?+

Yes, and that’s the normal case. Larstel sends them the sales invoice book and the month’s accounting entry in their format — or in Excel and CSV if they prefer. We don’t ask them to switch software: we send them the figures already reconciled.

03What about the invoices from the previous years?+

They’re kept. They come in as history you can consult and download, with their old numbering, and they don’t mix with the chain, which starts clean with the first invoice you issue in Larstel.

04Who answers if the tax authority asks?+

The books are yours and they come out of your system. We give you the file your tax authority asks for, the stored acknowledgement for every filing and the detail of the fingerprint chain. And that day we’re on the phone.

05Next step

Bring us last month’s close and we will tell you how much of this you are already doing by hand.

Thirty minutes, no obligation. If your current system is doing its job, we’ll tell you that too.
