Hidden Costs Breakdown

1

Additional Device Fees for POS Terminals

medium addon

Beyond the base subscription, each additional POS device (register, terminal) incurs a recurring monthly fee. For restaurant implementations, this can significantly increase total cost of ownership.

Square POS is 69/mo + 50/mo/device for the minimum anything beyond a popup or food truck would need [0], and $828/year minimum isn't exactly free, damn near doubled to $1428 if you have a second register.

2

Per-Device POS Fee

high addon

Beyond the first free card reader included with the Free plan, each additional POS device costs $50/month in restaurant configurations. A two-register setup effectively nearly doubles the monthly cost beyond the base subscription.

Square POS is 69/mo + 50/mo/device for the minimum anything beyond a popup or food truck would need [0], and $828/year minimum isn't exactly free, damn near doubled to $1428 if you have a second register.

3

Higher Transaction Fees vs. Traditional Merchant Accounts

high overage

Square's flat-rate processing (2.6% + 10¢ per card-present swipe on the Free plan) is higher than interchange-plus rates available to established merchants through traditional processors. High-volume businesses pay significantly more in transaction fees than they would with a dedicated merchant account.

Or nowadays you can go with Square Register and get dinged a lot more per transaction than the rate an established shop would be able to get.

hn

Whilst interchange is indeed the largest part of processing costs, there are still assessments (0.13%) and brand fees (FANF, cross border fees (1.25% for Visa), etc) that increase the cost of processing over interchange. Square can only hope to make a decent margin on its 2.75% pricing by 1. seeing a preferred distribution mix on card types (such as, high debit card usage; less Amex; less expensive rewards cards; high cards qualifying at card present rates & no downgrades) and/or 2. special interchange discounts with the networks based on growth initiatives and/or fraud tools.
