Payment Processing: Stop Losing Money on Every Sale
Every time a customer pays you with a card, a slice of that sale goes to a payment processor before it ever touches your account. Most business owners never actually compare that slice against what it could be — and when you're already fighting to keep cash flow positive, a fee you didn't have to pay is money you needed.
Here's the real math and my honest recommendation, not a list of ten options that all "could work."
What Actually Matters (Ignore the Rest)
- Flat-rate vs. interchange-plus. Flat-rate (like 2.6% + $0.15) is simple and predictable. Interchange-plus charges you the real card-network cost plus a small markup — usually cheaper once you're doing meaningful volume, but the bill looks more complicated. The crossover point where interchange-plus starts winning is usually around $5,000/month in card sales.
- How you actually sell. In-person, online, or both — the "best" processor depends entirely on this.
- Payout speed. Some processors pay out next-day, some take 2-3 business days. When cash is tight, this matters more than the rate.
- Hidden fees. PCI compliance fees, monthly minimums, early termination fees — read past the headline rate.
My Actual Recommendations
If you sell in person — walk-up, retail, service calls: Square. No monthly fee, transparent 2.6% + $0.15 in-person rate, and the POS hardware is genuinely easy to set up in an afternoon. This is the right default for a physical storefront or mobile service business.
If you sell mainly online — e-commerce, invoices, subscriptions: Stripe. Flat 2.9% + $0.30, no monthly fee, and it's built to handle everything from a simple checkout page to subscription billing. If you have a website that takes payments, this is almost always the right starting point.
If your monthly card volume is consistently over $5,000-10,000: Helcim. Once you're doing real volume, interchange-plus pricing will beat flat-rate every time — Helcim is transparent about it and doesn't bury you in fees to get there. Worth the switch once your volume justifies it.
If you run a restaurant and need integrated ordering: Clover. The hardware and ordering-system integration is genuinely built for food service in a way general-purpose processors aren't.
What I'd be careful with: PayPal as your only processor. It's fine as a secondary option some customers prefer, but its standalone rate (2.99% + $0.49) is the highest of the group, and it shouldn't be your primary processor if you have a choice.
The Math That Actually Matters
On $10,000 in monthly card sales, the difference between a 2.6% and 2.9% effective rate is $30/month — not huge on its own, but $360/year, every year, for as long as you don't switch. On $50,000/month, that same 0.3% gap is $1,800/year. If you're already tight on cash, that's worth 20 minutes of comparing your actual statement against a better rate.
Shop-Smarter Checklist
- [ ] Pull your last processing statement and calculate your actual effective rate (total fees ÷ total processed) — it's almost always higher than the advertised headline rate.
- [ ] Check your monthly card volume against the ~$5,000/month interchange-plus crossover point.
- [ ] Confirm payout speed — next-day vs. 2-3 days can matter a lot when you're managing tight cash flow.
- [ ] Ask specifically about PCI compliance fees and early termination fees before signing anything.
- [ ] If you sell both in-person and online, check whether one processor genuinely covers both well before running two separate systems.
