Case Study: Mr. Sandwich achieves 30% increase in sales with Toast Go handhelds and Online Ordering

After Switching from Square to Toast, Mr. Sandwich Increases Sales by 30% with Toast Go Handhelds and Online Ordering

Mr. Sandwich, a family-owned sandwich shop in Whittier, CA operating since 1980, faced the challenge of modernizing after more than 30 years as a cash-only business. After an unsatisfying stint with Square, owners needed a POS that could support flexible, build-your-own menu options, fast service for time-pressed customers, and a true online ordering channel.

They switched to the Toast Digital Ordering Suite—Toast POS, Toast Go handhelds, Online Ordering, and Reporting & Analytics—which enabled mobile ordering, customizable online menus, integrated payments with no third‑party fees, and data-driven decisions. The result was an immediate 30% increase in sales, over 40% of revenue now from online orders, faster service via handheld ordering, and actionable analytics (including a 300% beverage sales boost after a vendor change).
