How to Master the Subway POS When a Customer Orders Out of Order

Published on Thu May 07 2026

The most stressful part of working at Subway isn’t making the sandwich; it’s ringing it up.

At most fast-food places, the cashier takes the order and then the kitchen makes it. At Subway, the customer builds the sandwich in front of you, and you have to ring it into the Point of Sale (POS) system at the very end. The problem? Customers rarely tell you what they want in a logical order.

Here is how to master the Subway POS system and avoid charging someone the wrong price.

The 3-Step Core Ring

The Subway POS interface is actually designed to mimic the physical sandwich line. To successfully ring up a sub, you must hit three required modifiers in this exact order:

  1. Size: 6-Inch, Footlong, or Footlong Pro (Double Meat).
  2. Bread: Italian, Hearty Multigrain, Italian Herbs & Cheese, or Flatbread.
  3. Core Formula: Turkey, Spicy Italian, Meatball, Cold Cut Combo, etc.

If you do not hit all three of these in order, the system will not let you proceed to the payment screen.

The “Out of Order” Customer

The chaos happens when the customer says: “I want a Turkey on Wheat with extra cheese, bacon, and a drink.”

If you immediately press the “Bacon” button, the system will throw an error because it doesn’t know what sandwich the bacon belongs to yet.

The Fix: You must train your brain to filter the customer’s sentence into the 3-Step Core Ring. Ignore the bacon and the drink for a second.

  • Press: Footlong -> Wheat -> Turkey.
  • Now go to the “Add-Ons” tab and press Bacon and Extra Cheese.
  • Finally, go to the “Drinks & Sides” tab for the beverage.

The “Make it a Meal” Trap

Another common trap for new hires is the “Meal Deal.” If a customer buys a sandwich, a bag of chips, and a medium drink, they are entitled to a discounted combo price.

However, older Subway POS systems do not always automatically bundle this! You must physically press the “Make it a Meal” button on the screen and then select the drink and chip size. If you ring the chips and drink up individually as separate side items, you will overcharge the customer, leading to complaints.
