FAQ: 50 Common Questions About Restaurant POS Systems

The Basics

1. What is a restaurant POS system?

A POS (Point of Sale) system is the digital platform that registers sales, processes payments, and logs transactions. Modern restaurant POS systems also include table management, inventory control, staff scheduling, and reporting capabilities.

2. Do I need a POS system for a small restaurant?

Yes. Most jurisdictions require registered, compliant point-of-sale systems for food service establishments. Beyond regulatory requirements, even a small restaurant benefits from payment processing, basic sales tracking, and customer data management.

3. What's the difference between a POS register and a POS system?

A POS register is the formal hardware or core application that records sales. A POS system is the broader platform that includes the register, supporting software, reporting tools, and integrated features like booking and staff management.

4. How much does a restaurant POS system cost?

Costs vary significantly by vendor and feature scope. Simple systems start with low monthly fees but often lack features like table booking, Online Ordering, and staff management. Comprehensive integrated platforms like Vendion—starting from SEK 2,490/month—include the full platform in a unified cost. Additionally, you'll pay processing fees for card payments through a payment processor.

5. What is a control unit?

A control unit is a technical device connected to the POS register that logs every transaction. In regulated markets (like Sweden), it's required to prevent tampering with sales data. Requirements vary by jurisdiction.

6. Can I use an iPad as a POS register?

Yes, many modern POS systems run on iPad or tablet devices. Ensure the system is compliant with local regulations and has the necessary security features for your market.

7. What is a cloud-based POS system?

A POS system where data is stored on internet-based servers rather than locally. Benefits include: access from any device, automatic updates, no local server hardware required, and automatic data backups.

8. What's the difference between a general POS system and a restaurant-specific one?

General POS systems work across retAIl, services, and hospitality but often lack restaurant-specific features like table management, kitchen display integration, course timing, and booking. Restaurant POS systems are optimized for restaurant workflows.

Choosing and Switching Systems

9. How do I choose the right POS system?

Start with your needs: restaurant type, number of terminals, booking requirements, online ordering, staff scheduling. Compare total cost (not just base price) and which features are included versus added as premium costs.

10. Can I switch POS systems without closing my restaurant?

Yes. Plan the switch for a slow day, train staff beforehand, and keep the old system as backup for the first 24 hours.

11. What happens to my data when I switch systems?

It depends on the system. Most can export basic data (product catalog, sales history). Guest data and booking history may be harder to migrate. Ask the new vendor about data import options.

12. What should I avoid when choosing a POS system?

Avoid long lock-in contracts without exit options, hidden costs (hardware, add-ons, integration fees), systems without cloud backup, and vendors with poor support.

13. Do I need to buy hardware?

It varies. Some systems require specific hardware; others run on standard tablets. You typically need at least one tablet/screen and a card reader. A Kitchen Display System requires an additional screen in the kitchen.

Payment Processing

14. What is acquiring?

Acquiring is the service that processes card payments and deposits funds into your account. The acquirer charges a fee per transaction.

15. What is Interchange++?

A transparent pricing model where all components of card payment fees are listed separately: interchange fee (to the card issuer), network fee (to Visa/Mastercard), and the acquirer's fee. Offers better transparency than blended rates.

16. Should the card terminal be integrated with the POS?

Yes. An integrated terminal automatically transfers the amount from the POS—no manual entry, faster payment, fewer errors.

17. Can customers pay with mobile payment apps?

Yes, if your POS system and payment processor support them. Vendion supports mobile payment options including Swish and other digital wallets.

18. How does tipping work at a card terminal?

Modern terminals can display suggested tip amounts on the screen. The customer selects an amount or percentage before payment is processed. The tip is recorded separately in the POS system.

Table Booking

19. Do I need a separate booking system?

Not if your POS system has integrated table booking. Vendion includes table booking in the platform, so booking data links directly to sales data and guest profiles.

20. What's the benefit of integrated booking?

Guest profiles with complete history, AI-powered forecasts based on booking status, automatic no-show handling, and a unified view for staff.

21. How do I reduce no-shows?

Send SMS reminders 24 hours before, require a card guarantee for bookings, maintain a waitlist to fill cancelled tables, and analyze which guests have high no-show rates.

22. Can bookings be linked to Google?

Yes. Vendion's booking system can connect to Google Business Profile so guests can book directly from search results.

23. What is RevPASH?

Revenue Per Available Seat Hour—the revenue generated per available table seat per hour. It measures how efficiently you use your seating capacity and combines occupancy with average check size.

Staff Management

24. What is a staff register?

A mandatory log that food service establishments in regulated markets must maintain. It should document names, identification numbers, and work hours for all employees. Requirements vary by jurisdiction, but proper documentation protects both business and employee.

25. What happens if the staff register is incorrect?

Requirements and penalties vary by jurisdiction. In Sweden, Skatteverket can impose significant fines for inadequate documentation. Proper digital records prevent costly compliance issues.

26. Can the POS system handle staff scheduling?

Some can. Vendion's staff module includes scheduling linked to booking data and sales history. Standalone scheduling tools exist but lack integration with sales data.

27. How do I reduce labor costs without sacrificing service?

Schedule based on guest flow (linked to bookings and sales data), cross-train staff in multiple roles, and automate repetitive tasks (QR ordering, express checkout, digital staff records).

28. Can staff see their schedules in an app?

In Vendion, staff can view schedules, request time off, and swap shifts via the app.

Online Ordering and QR

29. What is QR ordering?

A guest scans a QR code at the table, views the menu on their phone, orders and pays. The order goes directly to the POS and kitchen display.

30. Does QR ordering increase average check?

Yes, typically by 10–20 percent. Guests browse the menu at their own pace, see photos, and upsell suggestions are presented without social pressure.

31. Can I have my own ordering page instead of using third-party delivery platforms?

Yes. Vendion's online ordering gives you your own ordering page with zero commission. You own the customer data and control the experience.

32. Does your own online ordering charge commission?

With Vendion: zero commission. You pay the platform fee and standard payment processing fees for card transactions.

33. Does online ordering work for catering?

Yes, if the system supports advance ordering with date and time selection. Vendion's online ordering can be configured for catering menus with advance booking.

Kitchen Display

34. What is a Kitchen Display System (KDS)?

A digital screen in the kitchen that displays orders instead of printed tickets. It provides clearer communication, timing, and automatic routing to workstations.

35. Do I need KDS?

If you have more than 50 seats, multiple kitchen stations, online ordering, or frequent missed orders—yes. Small cafés with simple menus often manage with a ticket printer.

36. What is routing?

The function that automatically sends different parts of an order to the correct kitchen station. Salads to the cold station, steaks to the grill, desserts to the pastry station.

37. What is course timing?

Synchronizing food preparation so all dishes for a table are ready at the right moment. Appetizers first, then entrées, then desserts.

38. What hardware do I need for KDS?

A standard tablet or touch screen is sufficient. Vendion's KDS runs on standard tablets—no specialized hardware required.

Marketing

39. Can the POS system send SMS to guests?

Yes, some systems can. Vendion's marketing tools include SMS campaigns based on guest data: reactivation offers, birthday messages, promotions.

40. What is a loyalty program in a restaurant context?

A system that rewards repeat customers through points, punch cards, membership tiers, or exclusive benefits. It works best when integrated with sales data and automated.

41. How important is Google Business Profile?

Extremely important. It's the first thing potential guests see in local search. An optimized profile with photos, reviews, and booking links may be your most valuable marketing investment.

42. How do I handle negative reviews?

Always respond. Thank them for feedback, apologize for their experience, briefly explain what you're doing about it, and invite them back. Never argue publicly.

Analytics and Data

43. Which key metrics should I track daily?

Average check size, food cost percentage, labor cost as a percentage of revenue, table occupancy, and beverage sales percentage. Real-time data lets you act immediately.

44. What is food cost?

The cost of ingredients as a percentage of menu price. Calculated as: Ingredient Cost / Menu Price × 100. Should typically be under 30–32 percent, depending on restaurant type.

45. What is prime cost?

The sum of ingredient costs and labor costs. The most important combined metric. Should be kept under 65 percent.

46. What does real-time data mean?

You see what's happening right now—current sales, occupancy, labor costs—not yesterday's or last month's figures. Vendion's dashboard displays real-time data.

AI and the Future

47. How is AI used in restaurant POS systems?

AI can provide sales forecasts (based on history, weather, bookings), menu optimization (identify profitable versus unprofitable dishes), staffing suggestions (match forecast to schedule), and food waste reduction (smarter purchasing based on predictions).

48. Do I need AI in my POS system?

AI provides the most value for restaurants with at least 3 months of data history. It's not essential, but it provides decision-making insights that improve over time. Vendion's AI features are built into the platform.

49. What is an integrated restaurant platform?

A system where POS, booking, staff management, online ordering, kitchen display, marketing, and analytics are built as a unified whole sharing the same data—unlike separate systems connected through integrations. Vendion is an example of an integrated restaurant platform.

50. Why is integration important?

Separate systems create data silos—bookings don't know what sales occurred, staff schedules ignore booking status, marketing lacks guest history. An integrated platform gives all functions access to the same data, enabling better decisions and reducing manual work.
