Step 4: Key Questions for Vendors
1. What is the true total cost of ownership for first year?
Include: setup, monthly fees, payment processing fees, hardware, training, support.
2. How long is the contract and what are cancellation terms?
Avoid multi-year commitments. Month-to-month is ideal for testing.
3. What happens if the service goes down?
Verify uptime guarantee (99.9%+), offline mode capability, backup systems.
4. Can we get a free trial before committing?
Best vendors offer 30-day free trials or demo environments.
5. What integrations are available?
Ask specifically about accounting, delivery, customer management, payroll software you use.
6. Who owns our data and can we export it?
You should own data. Export capability ensures you're not locked in.
Step 5: Calculate ROI
ROI Calculation Framework
Annual POS Cost:
Setup (one-time amortized) + (Monthly Fee × 12) + (Payment Processing Fees)
Expected Annual Benefits:
- Reduced labor costs: Efficiency gains × hourly rate × hours saved
- Food waste reduction: Waste % × food costs
- Increased average check: Upselling %, check increase %, annual covers
- Customer retention: Retention % improvement × LTV
Payback Period = Annual Cost ÷ Annual Benefits
Good systems: 3-6 month payback. Great systems: 1-3 months.
Step 6: Implementation Planning
Pre-Implementation Checklist
- Internet connection verified (minimum 10 Mbps recommended)
- Hardware ordered (tablets, cash drawer, receipt printer, card reader)
- Menu items documented with descriptions and prices
- Staff training schedule planned
- Go-live date scheduled for low-traffic period
- Backup plan if system fails on opening day
Red Flags: Avoid These POS Systems
❌ Long-term contracts with early cancellation fees
❌ No free trial or demo available
❌ Poor reviews or low ratings (below 4/5 stars)
❌ Unclear pricing or hidden fees
❌ No data export capability or vendor lock-in
❌ Slow or unresponsive customer support
FAQs
How do I know which POS system is right for my restaurant?
Evaluate based on: restaurant type (fast casual, fine dining, quick service), size, current pain points, budget, integration needs, and growth plans. Free trials help verify fit.
Should I buy or rent POS software?
Renting (SaaS/cloud) is preferred: lower upfront cost, automatic updates, accessibility. Buying (traditional) requires capital but offers ownership. Most restaurants now choose cloud.
How much should I budget for POS software?
Free tier: $0-0. Paid cloud: $50-300/month. Traditional POS: $2000-10000 setup + $200-800/month. Budget 3-6% of monthly revenue for POS operations.
What if my choice is wrong? Can I switch?
Yes, but switching has costs and disruption. Choose carefully. Most modern cloud POS systems support data export, making migration easier than traditional systems.
Do I need local support for POS software?
Not required. Cloud POS systems provide 24/7 online support (chat, phone, email). Local IT support only needed for traditional on-premise systems.
