Who we are.

We're a young team — many years deep in IT, raised on the internet, with a love for hospitality.

It started with a request for the manual of a POS older than most of our team. At the next restaurant we built our own ordering and delivery system — stable, fresh, fitting the business.

That made it clear: the gap is real. So we founded ByteServ.

Today we're a team of four engineers. Small enough to stay nimble. Big enough to deliver the service our customers need — in person on weekdays, and through our emergency hotline on weekends and holidays.

No off-the-shelf — only the right fit for your business. Because we know how fast bad tech costs revenue.

Our in-house products.

From SMEs, for SMEs. Some things we built ourselves, others come from strong partners. You can also use our systems standalone — we'll check for free whether we can integrate them with what you already run.

Common questions

Questions about POS, card payments and ordering.

What do I get from ByteServ, all from one source?

The tech your business runs on every day: a POS system with TSE, card payments through BytePAYMENTS and, with ByteORDER, your own ordering system for pickup, delivery and table service. We also build websites, set up networks and guest Wi-Fi, and develop custom solutions when off-the-shelf doesn't fit. No back-and-forth between providers: you have one contact for everything.

What does a POS system from ByteServ cost?

From €39.80 a month (excl. VAT, with a Shift4 card acceptance contract). That rents you the posmatic MinOne with a 10.1-inch touchscreen, built-in receipt printer and card terminal, with 3 years of TSE included. The larger MaxOne with a 15.6-inch display starts at €49.80. Rather buy than rent? Then the software costs from €19.99 a month. The ByteSTART packages come with no setup fee.

What do card payments cost, and do I need a new POS for them?

That mainly depends on your turnover and typical bill size. Together with our payment partners, we find the plan that fits your business, including options with no monthly fee and a free terminal. You don't need a new POS for it, and if you like, we'll check whether we can offer you card acceptance on your existing terminal. Payouts usually arrive within one business day.

Is there a POS system that connects to Lieferando and Wolt?

Yes. Through our partner Mergeport, orders from Lieferando, Wolt, Uber Eats and Foodora go straight into your POS. No more three tablets in the kitchen, no retyping. And because the platforms take up to 30% per order, we can also build your own ordering shop with ByteORDER: commission-free, under your logo, live in about 2 weeks. ByteORDER's direct POS connection is coming soon.

POS for delivery services
Do I need a TSE, and is it included?

Yes, and yes. Since 2020, every electronic cash register in Germany has to secure its transactions with a certified technical security device (TSE), as required by § 146a AO and the KassenSichV. Our posmatic packages include the TSE for 3 years plus data backup for GoBD-compliant record keeping. Software updates, including those for legal changes, come at no extra cost.

More on TSE compliance
Will you come out in Bonn when the tech fails?

Yes. Our office is on Maxstraße in Bonn, and we look after businesses in Bonn, Cologne and the surrounding area. Depending on the problem, we help by phone, by remote access or on site. On weekdays you reach us in person; on weekends and public holidays, through our emergency hotline. You won't end up in a ticket system; you talk directly to one of our four technicians.

What does the planned cash register mandate mean for my business?

On 23 September 2026, the German cabinet approved a draft law: businesses with more than €100,000 in annual turnover would need an electronic register with a TSE from 1 January 2028. Businesses with no more than €12,000 in cash sales a year are exempt. A digital receipt, for example via QR code, would replace the paper one, though customers who explicitly ask for paper still get one. The Bundestag and Bundesrat still have to approve it. Our posmatic registers already support both a TSE and digital receipts.

The 2028 mandate in detail
Do I have to take everything from you?

No. POS, card payments and ordering also work on their own, and we check for free whether they work with your existing system. If your register still runs without a certified TSE, though, you need to upgrade or switch anyway: the transition period for older devices ended in late 2022.
