Choosing a POS system: software fees vs payment processing
Compayr Editorial · · 7 min
A point-of-sale system is really two purchases wearing one badge: the software that runs your counter, and the payments engine that takes the money. Confusing the two is how merchants end up paying a premium processing rate to get a feature they could have had for a flat monthly fee. This guide keeps the two bills separate so you can compare the real cost.
The 30-second version
- A POS bill has two parts: a software subscription (per month, per register) and a payment processing rate on every sale.
- Bundled POS (software + payments from one vendor) is convenient but can lock your processing rate.
- Bring-your-own-payments POS lets you shop the processing rate separately — often cheaper, sometimes fiddlier.
- Industry fit matters: hospitality and retail need very different features.
- Model the monthly cost, software plus processing at your volume, before you commit.
Two bills, not one
The software fee buys the register app, inventory, staff logins, reporting and integrations. It's usually a fixed monthly subscription and scales with the number of registers or add-on modules.
The processing fee is a percentage of every card sale and is where the big money is over a year. A $30/month software saving is nice; a 0.3% processing difference on $40,000 a month is $120 — every month. Always weigh them together. Our POS comparison ranks POS systems on the card rate plus the POS subscription, so neither hides the other.
Bundled vs bring-your-own
Bundled systems (payments built in) are the fastest to set up and the easiest to support — one vendor, one login, one bill. The trade-off is that your processing rate is often fixed by the bundle, so you can't shop it.
Bring-your-own-payments systems let you pair best-in-class software with a separately negotiated processing rate. That can save real money at volume, but you own the integration and support hand-offs.
Neither is automatically cheaper. The deciding factor is your turnover: the higher your card volume, the more a competitive processing rate outweighs the convenience of a bundle.
Industry fit
| Business type | Features that matter most |
|---|---|
| Cafe / hospitality | Fast order flow, table maps, tipping, kitchen printing |
| Retail | Inventory depth, barcode, purchase orders, variants |
| Services / appointments | Bookings, deposits, recurring invoices |
| Multi-site | Central reporting, per-store permissions, stock transfers |
Buying a hospitality-first POS for a clothing store (or vice versa) is a common and costly mismatch. Shortlist on the features you'll use daily, then compare cost.
What the reforms mean for POS buyers
From 1 October 2026 you can't surcharge eftpos, Mastercard or Visa card payments, so the processing rate baked into your POS becomes a straight cost. If your system bundles payments at a premium rate, that premium is now yours to absorb. It's a good moment to check whether your POS lets you shop the processing side — and to compare against standalone terminals if payments are your biggest line.
What to ask before you sign
- What's the monthly software fee, per register, and which features are add-ons?
- Is payment processing bundled, and can I use my own provider?
- What's the processing rate, all-in, at my volume?
- What hardware is required, and do I own or lease it?
- Is there a contract term, and what's the exit cost?
