Navision or BC365 (Business Central 365) with a technical security setup for cash registers? Of course!
If you have an open cash drawer (such an old wooden thing from grandmother's time) and you still keep your cash book with a goose quill and ink on paper - then everything is fine. This is actually still permitted today (as of 2025), there is no obligation for an electronic cash register (also as of 2025).
That can change though! That BFM has announced that from 2028, companies with sales of more than 100,000 euros and/or cash transactions/money transfers of more than 12,000 euros per year will be subject to the new regulations., There is a mandatory requirement to introduce an electronic register system. Officially, of course, in the form of „simplification“ and „reduction of bureaucracy“… But here, of course, just as with the xRechnung, the goal is to squeeze even more out of the operators of the German economy. Admirably, the BMF even corrects the factually incorrect statement „Those who cheat on cash transactions harm the vast majority of retailers and other companies that pay their taxes correctly.“ and already in the next paragraph corrects the correct factual statement „…and at the same time ensures fair competition between honest companies.“ You can assume that your open cash register system will have to be replaced by an electronic register system by 2028. However, „Electronic register system“ here is not really correct; the collection of payments / the cash register process must be replaced by a Paragraphs §146A of the Tax Code are sufficient.
With Navision or BC365? Is that possible? Yes!
However, if you have Navision or BC365, and you also have a retail store, then processing the cash sales (credit card sales, voucher sales, etc.) via Navision/BC365 is just a logical step. And already after paragraph 146a of the Tax Code you have an „electronic cash register system that has a certified Technical Security Facility (TSE)”. have to, To record and store all transactions securely from manipulation. Since January 1st, 2023, it has been mandatory in Germany for all electronic cash registers to record all transactions. Even if you don’t process your cash sales with an open cash register or a proper register (like the one at the metro), but with your own software solution like Navision Financials.
The transition deadlines have now largely expired (as of 2025), however, you can still request a postponement if you can prove that you are actively working to retrofit this TSE (Technical Safety Device).
A TSE can be integrated into Navision both via hardware (USB token) and via a pure software solution (REST Api). The process is essentially the same as for any other cash register, but somewhat condensed:
As soon as an invoice or receipt with a cash reference (cash, cheques, vouchers, etc.) is printed, a TSE transaction number is requested before printing. The associated information is stored on the invoice and printed on the paper. After printing, the transaction is closed.
My solution seamlessly integrates the fiskaly TSE into your Navision!

Create TSE in Navision
Please call up the TSE setup, then button TSE, entry TSS (Technical Security System). Assign a code of your choice (e.g. 0001) and then call TSE/register. Navision now contacts the Fiskaly server via REST Api and registers this TSE.

Your TSS/TSE is now ready for operation. As a rule, you only need one TSS in your company. If you have a large number of signature processes (e.g. a wholesale market or a shopping mall with dozens or hundreds of tills), it may be helpful to create several TSS/TSEs and distribute the individual tills to these TSSs. Please contact me beforehand for such scenarios.
Create TSE Client
There are different approaches to how many clients you need. For example, one client for your entire company, or one client per salesroom, or one client per cash drawer.
Fiskaly recommends one client per site.
My recommendation here is: One client per busy business location with many checkout processes per day.
Please remember that you are missing the open cash drawer/cash drawer drawer and the use of your Navision TSE or BC365 TSE according to Paragraph 146a of the Tax Ordinance They also have to register with their tax office!

The notification under paragraph 1 must be submitted within one month after the electronic recording system is purchased or put into service.
