MakeChange: Never Count Back Change Wrong at a Craft Fair Again

Published June 8, 2026 • VARO Industries

The Problem With Counting Change Under Pressure

You've got a line of customers, someone hands you a $50 bill for a $17 item, and your brain momentarily goes blank. It happens to every vendor. Counting change manually while talking to a customer, keeping an eye on your booth, and processing the next transaction is a recipe for math errors — and errors cost you real money.

MakeChange is a free browser-based tool that eliminates that moment of panic entirely. Enter the sale total and the amount tendered, and it instantly shows you the exact bills and coins to hand back.

How MakeChange Works

The interface couldn't be simpler. You type in two numbers: what the customer owes and what they handed you. MakeChange does the subtraction and breaks the result down into the fewest possible bills and coins — no guessing, no mental arithmetic.

If a customer pays $60 for a $43.75 item, you'll see exactly: one $10, one $5, one $1, one quarter. That's it. You can read it off in seconds and hand it over confidently.

Why It Matters for Craft Fair Vendors

Many vendors rely solely on Square or Stripe for card payments and keep minimal cash on hand. But at outdoor markets, card readers fail, cell service drops, and plenty of customers still prefer cash. Having a fast, reliable change calculator on your phone means you're never caught off guard when a customer pulls out a $100 bill.

It also helps newer vendors who are still building confidence handling cash quickly at a busy booth.

Works Offline — Even in Dead Zones

Outdoor markets are notorious for poor cell coverage. MakeChange is designed to work fully offline once the page loads. Open it before you leave home, leave the tab open, and it will keep working throughout your event even if you lose signal entirely. No app to download, no account to create.

Part of the Free Vendor Toolkit

MakeChange is one of several free tools built specifically for craft fair and market vendors. If you also need to calculate credit card processing fees, check out FeeCut — or browse the full suite at VendorTools.app.
