A TSE secures the individual records in your POS system. But it doesn't write a cash book: change float, private withdrawals, bank deposits, tips, and cash discrepancies remain manual work, and that's exactly what falls behind. NordFlux builds the path from the daily closing through the cash report to the tax office, with a balance that matches the counted cash every evening.
In hospitality, retail, and hairdressing businesses, the till runs all day, but nobody writes up the cash book in the evening. At month-end, the owner sits with a stack of Z-reports, a spreadsheet, and the question of what the 80-euro withdrawal on the 14th was actually for.
We replace neither your POS system nor your TSE, and we don't provide any tax assessment. We build the path from the till into the cash book and from there to the tax office.
After closing time, the Z-report and the DSFinV-K export are fetched automatically from your POS system and transferred into the cash book, instead of being typed up the next morning. Revenue is kept separated by tax rate, with EC and card payments cleanly distinguished from cash. With multiple tills or branches, all daily closings feed into one overview that shows which till is still missing.
Savings 2–4 h per weekAnyone working without an electronic till counts the cash in the evening and works backward from the closing balance to the day's takings. For that, we provide a short input screen on a phone or tablet: enter the quantity of each coin and note, and the cash report calculates retrograde and stores itself unchangeably. The count log isn't mandatory in every case, but in an audit it's what makes your figures credible.
Effect Daily closing in 5 minutes at the counterPrivate withdrawals, change float deposits, and cash deposits into the business account are the entries where a cash book falls apart in an audit. The workflow asks directly for the reason and the receipt with every withdrawal, instead of postponing it to later. The bank deposit is automatically reconciled against the withdrawal from the till so both sides match.
Effect no unexplained cash movementsIf the counted balance deviates from the target balance, the difference is recorded as its own line and assigned to the day and the till, not quietly corrected. Above a threshold you set, a notification goes to management. Over the weeks, this builds into an analysis that shows whether discrepancies are tied to a particular shift, till, or operating error.
Effect discrepancies are noticed the same dayA cash register inspection arrives unannounced, and then what matters is how quickly the cash data for the requested period can be put on the table. We store DSFinV-K exports, Z-reports, cash reports, and count logs so that a period can be output in one go. The same package goes to your tax office or accounting system monthly, in the agreed format instead of as a stack of photos.
Savings receipt search from hours to minutesWe're not locked into any one tool, and we don't sell tills or TSEs. We work with the POS system you already have.
Connecting till, bank, and accountingThe POS system, business account, and accounting software don't talk to each other on their own. n8n fetches the daily closing and the DSFinV-K export, reconciles the bank deposit against it, and passes the result on. On request, n8n runs on a server in Germany so your revenue data never leaves the building.
POS system without an interfaceMany POS systems in small businesses have no open interface, just a screen and an export button. In that case, a software robot takes over exactly the clicks a person makes today: log in, select the period, export, save the file. It's no beauty contest winner, but it's the way to connect an old system without having to replace it.
Most tax offices want cash data in a fixed format on a fixed date. We coordinate the handover format directly with your tax office and deliver the monthly package there automatically, whether DATEV, Lexware, or sevDesk. What the DATEV route looks like in detail is covered on its own page.
From the first conversation to a running cash book in 30 days, at a fixed price instead of an open-ended timesheet.
60 minutes, no obligation: we look at which POS system you're running, who currently does the daily closing, and where your tax office regularly gets stuck. Afterward, you'll know which part is worthwhile.
You get a concrete proposal: which tills we connect, how the daily closing and cash report will run, and what it costs. One figure, no surprises.
We build the route and run it alongside your existing cash book for a full month. You compare balance and entries day by day before we switch over, including the days with discrepancies.
Your team gets a briefing at the counter and documentation showing where you can step in. On request, we take over operations with a fixed service level, and on request we submit the process documentation to your tax office for review.
This page covers the cash route: daily closing, cash report, discrepancies, handover. If incoming invoices, bank reconciliation, and travel expenses also pile up at month-end, the accounting page describes the overall process from receipt to tax office.
In the free initial analysis, we go through your cash day and calculate what the daily closing and upkeep cost today. 60 minutes, no obligation, no sales pressure.
A spreadsheet doesn't meet the requirement for immutability, because any row can be changed retroactively without the change staying visible. That's exactly the point where cash books are regularly rejected in audits. We therefore keep the cash book in a system with a log: every change stays visible as a change, instead of overwriting the original figure. Whether your specific setup is sufficient is assessed by your tax office, not by us.
The TSE and the cash book solve two different tasks. The technical security device secures your POS system's individual records against subsequent manipulation, but it captures neither private withdrawals nor change float deposits, bank deposits, or cash discrepancies. The cash balance only results from both together. It's exactly that second half we automate.
No, there is no legal requirement to use a cash register in Germany; the open till is still permitted. But if you use an electronic recording system, it must have a certified technical security device, and the use of such systems must be reported to the tax authority via ELSTER. With an open till, the daily cash report takes center stage instead. Which variant applies to you and which deadlines run should be clarified with your tax office.
A cash-book bookkeeping obligation doesn't apply to you in this case, but the obligation to individually record your cash receipts does. In practice, many EÜR businesses still keep a daily cash report anyway, because otherwise they can't prove their cash receipts in an audit. The automation here is the same; only the resulting document is named differently. What specifically applies to your legal form is something your tax office can tell you.
The price depends on how many tills are connected and whether your POS system has an interface or has to be operated via its screen, so we won't quote a flat rate out of thin air. After the free initial analysis, you get a fixed price for a clearly defined scope. For a single till with only a few cash movements per day, we'll tell you honestly if the effort isn't worth it.
