Is Flat-Rate Pricing Costing You More Than It Should?

Flat-rate pricing is simple, but even small rate differences can have a real impact over time.

A lower flat rate can make a bigger difference than most businesses think.

Flat-rate pricing is popular for a reason.

It is simple, predictable, and easy to understand. One rate, straightforward fees, and no complex pricing statements.

For many businesses, that convenience makes sense.

But not all flat-rate pricing is the same, and even small differences in rates can become meaningful costs over time.

That is why comparing your options matters.

How Flat-Rate Pricing Works

With flat-rate pricing, you typically pay a percentage of each sale plus a small transaction fee.

For example, a provider such as Square may charge around 2.6% + $0.10 for in-person transactions, while Quantum ePay offers qualifying businesses rates as low as 2.4% + $0.10.

At first glance, the gap looks minor. Over time, tha gats bigger in....


For example, on a $100 transaction:



On Square’s 2.6% + $10.10:

  • $2.60 percentage fee
  • $0.10 transaction fee
  • $2.70 total

On Quantum’s 2.4% + $0.10:

  • $2.40 percentage fee
  • $0.10 transaction fee
  • $2.50 total

That is a $0.20 difference on one sale.


Now multiply that across hundreds or thousands of monthly transactions.

Why Small Pricing Differences Matter

As payment volume grows, even modest savings per transaction can help improve:

monthly profit
operating margin
available cash flow
room to reinvest in growth

That is why many businesses revisit flat-rate pricing once sales begin to scale.
