POS System for Small Business: What to Know Before You Buy

What are the legal requirements for a POS register?

Every registered taxpayer accepting cash payments must have a cash register connected to the tax authority's system for fiscal confirmation. Every receipt must be confirmed in real time — either via the internet or in offline mode with subsequent confirmation.

Penalties for an unconfirmed receipt range from €800–€5,000 for individuals and up to €25,000 for companies. Inspectors check this by scanning the QR code on the receipt — they see in one second whether it's been fiscally confirmed.

What are the key features of a good POS solution?

Beyond legal compliance, a good POS provides: fast item entry (by scanning or searching), a daily revenue overview by product and category, inventory management (stock automatically decremented on sale), card and cash payment acceptance, and e-invoice or PDF receipt for customers.

A POS that can't do this isn't a POS — it's a calculator with a printer.

How much does a good POS solution cost?

Prices range from €30 per month (basic mobile solution) to €200+ (dedicated hardware with accounting integration). For businesses with up to 5 checkout positions, a mobile or tablet solution is often optimal — lower cost, same legal compliance, easy updates.

Watch for hidden costs: transaction fees for card payments, hardware servicing, and separate licences for each checkout position.

How does POS connect sales to accounting?

The best POS solutions integrate with accounting software and automatically create a ledger entry for every transaction. This means: at day-end there's no manual data transfer, no entry errors, no reconciliation between the cashier and the accountant.

POS–accounting integration saves 1–3 hours of work monthly in small businesses — and makes the annual tax review trivial, because all data is already in the system.
