A % Fee.
On Every Sale.

§ 02 — How it works

Set it once.
Then forget it.

No price changes. No card-type detection. The POS adds a percentage-based line item to every transaction. Customers see it, the receipt shows it, and you offset processing costs across every sale — scaling naturally with ticket size.

01 · Set the fee

Set the rate.

Most merchants set a supplemental fee of 3.5% of the transaction total. We help model the right rate based on your average ticket and processing costs.

02 · POS adds the line

Auto-applied at checkout.

The POS appends the fee to every transaction automatically. No card-type detection, no manual math — the percentage is calculated and added instantly.

03 · Receipt itemizes

Listed plainly.

The fee appears as its own clearly-named line item on every receipt. Customers see exactly what's being charged and why.

§ 03 — Your fee, your name

Call it
anything you want.

One of the biggest advantages of Supplemental Fee: you choose the name on the receipt and signage. The only rule — it cannot include the word "card," "credit," or "surcharge." Everything else is fair game.

One simple rule: The fee name cannot include "card," "credit," or "surcharge." Beyond that, you have full flexibility — match it to your brand, your industry, or what feels most natural to your customers.
§ 04 — Honest comparison

The trade-offs,
up front.

Supplemental Fee is the simplest program to run, but it applies to everyone — including cash customers. Here's what to weigh.

What works

Pros
  • ✓Recovers fees on every sale — including cash. Visa Surcharge hits credit only. Cash Discount reduces what cash customers pay. Supplemental Fee is the only program where every transaction, card or cash, generates recovery.
  • ✓Simplest to operate. One percentage rate, one POS setting. No card-type rules, no price changes.
  • ✓No menu changes. Posted prices stay the same. No reprinting, no relabeling.
  • ✓Predictable revenue. You know exactly what the fee adds per transaction.
  • ✓Legal in 50 states. No state restrictions, no special filings.
  • ✓Works on any POS. Any system that supports a custom line item works.

What to weigh

Cons
  • −Cash customers also pay. Unlike Surcharge or Cash Discount, there's no exemption — every customer sees the fee.
  • −Customer perception. Some customers push back on "extra fees" even when properly disclosed.

correctly.
