Flat-Rate Transaction Fees

high overage

Square uses flat-rate transaction fee pricing on all sales, including on the free plan. Unlike interchange-plus pricing models, flat-rate pricing can cost more at higher transaction volumes, as the per-transaction cost does not decrease with scale.

Look for a provider that does interchange plus pricing! It's basically cost plus pricing. So you pay the true cost of the credit card transaction (cost varies depending on the type of card the customer uses), plus a small margin from the provider. For auto repair, this is one of the cheapest ways to go. It will save you tons compared to a flat rate like Square is offering.

Example: True Cost for 25 Users

License (25 × $49 × 12) $14,700/yr
Credit card processing fees +2.6-3.5% of transaction volume
Additional card reader hardware +$10 per additional reader
Flat-Rate Transaction Fees +2-3% of gross transaction volume
Estimated Year 1 Total ~$24,990
That's roughly 1.7× the advertised license price. The median Square POS contract is $1,000/yr across 69 Vendr purchases.
