What Build Means for QSR Operations

Build phase focuses on POS systems, kitchen display systems (KDS), payment processing, and inventory. Toast, Square for Restaurants, or Clover are industry standards: they integrate ordering, kitchen tickets, staff management, and reporting. Your system must support fast transactions, real-time inventory, and integration with delivery platforms (DoorDash, Uber Eats API).

The 3 Decisions That Determine Your Outcome

First: POS platform—Toast ($0/month + 2.9% + $0.30/transaction) vs. Square ($0–$99/month) vs. Clover ($0–$115/month). Second: kitchen workflow—open kitchen vs. ticket-line KDS (impacts labor efficiency 15–25%). Third: payment processing—integrated or third-party gateway? Unified reduces errors and PCI compliance headaches.

What to Analyze Before Committing

Request demos from Toast, Square, Clover. Test on realistic order volumes (10 orders/minute during lunch). Verify integrations with DoorDash, Uber, Grubhub. Review reporting: daily P&L, labor tracking, inventory variance. Confirm PCI compliance and security.

Common Mistakes at This Stage

Choosing cheap POS ($20/month) lacking critical reports or integrations. Underestimating setup time (3–6 weeks). Not accounting for payment fees (2.5–3.5% of revenue—material). Ignoring network resilience.
