How to Choose a POS System for a Restaurant: A Guide with Checklist

Choosing a POS system is a decision you make once and live with for years if you get it wrong — migrating to another system means re-entering the menu, retraining staff, and a stretch where nobody’s quite sure where anything is. This is a checklist of questions worth asking before signing a contract, not after the first week of service.

1. Does fiscalization work out of the box

This is the first filter, not the last. If a POS system doesn’t have fiscalization built in and compliant with Serbian law, you’re left manually transferring data between two systems — exactly the problem the POS is supposed to solve, not create. More in Restaurant Fiscalization in Serbia.

2. Do inventory and billing share the same system

In many smaller venues, stock is still tracked in a notebook or a spreadsheet, separate from the till. The problem is that nobody knows in real time whether an ingredient is running low until it runs out mid-shift. A POS system that automatically deducts ingredients from stock with every sale gives the owner visibility that manual tracking never quite catches up to. More in Restaurant Inventory Management.

3. Does delivery (Wolt, Glovo) plug directly into the system

If you run or plan to run delivery, check whether orders from aggregators flow directly into the POS, or whether someone has to manually retype them from a tablet or phone into the kitchen system. The latter is a frequent source of errors and delays in restaurants with meaningful delivery volume. See Wolt and Glovo Delivery for Restaurants.

4. Pricing structure — what’s included, what’s extra

When comparing offers, ask for a broken-down price structure, not just a monthly subscription figure:

• subscription per terminal/month (basic packages for smaller venues in Serbia start around €39/month),
• one-time installation and equipment setup,
• the fiscal (LPFR) license — often billed separately,
• add-ons: a waiter app, delivery integration, real-time analytics.

The offer that looks cheapest at first glance often doesn’t include the fiscal license or installation — compare total monthly cost, not just the headline number.

5. Local support and response time

When the system freezes on a Friday night during rush hour, what matters is how fast someone responds and whether they understand the context (language, local regulations, your specific hardware). A system with support in a different time zone, or no local partner, can mean hours of waiting exactly when waiting is most expensive.

6. Staff training and the learning curve

Ask how long it typically takes a new server to learn the system, and whether the provider includes training as part of implementation or charges extra for it. A system that looks powerful in a demo but takes staff weeks to learn will cost you in mistakes and slower service in the first weeks.

7. Analytics — do you see what you actually need, not just what the system offers

A genuinely useful report for a restaurant owner answers three questions: which dishes/drinks sell best, what’s the average table turnover per shift, and where are losses occurring in inventory. Check whether the system surfaces this clearly, without you having to build your own tables from raw data.

Quick checklist for a demo call

• Fiscalization is built in and compliant with the law
• Inventory updates automatically with every sale
• Delivery (Wolt/Glovo) connects directly, without manual entry
• Pricing is transparent: subscription + installation + fiscal license + add-ons
• Local support exists, not just an email ticket in another country
• Staff training is part of implementation
• Analytics answer the questions you actually need, not just generic numbers

Frequently asked questions

How much does a POS system cost for a small cafe in Serbia? As a rough guide, basic packages start around €39/month per terminal, plus a one-time installation fee. Price increases with the number of terminals and add-on modules (delivery, waiter app).

Is it cheaper to use a generic till and separate inventory software? It might look cheaper in the short run, but two separate systems mean manually reconciling data between them — which in practice costs more time (and creates more errors) than the price difference of an integrated solution.

How long does switching from an old system to a new POS take? It depends on the size of the menu and the number of terminals, but a good provider includes migrating existing data (menu, inventory) as part of implementation, not something the owner does from scratch.
