Merchant Services Pricing — What San Diego Businesses Actually Pay
Merchant services sales reps are incentivized to confuse you. Tiered pricing, bundled fees, non-compliance penalties — most business owners have no idea what they're actually paying. This is the decoder.
The 4 pricing models — and which one you're probably on
| Model | How it works | Best for | Warning |
|---|---|---|---|
| Flat-rate | Same % for every card (e.g., 2.6% + $0.10 in-person) | Low volume, simple setup | Overpays on debit cards |
| Interchange-plus | Actual interchange rate + fixed markup (e.g., +0.3%) | $10k+/month businesses | More complex to read statements |
| Tiered / Bundled | Cards sorted into "qualified / mid / non-qualified" tiers | No one — favor for processor | Non-qualified rate can hit 3.5–4% |
| Subscription | Flat monthly fee + interchange passthrough (e.g., $20/mo + 0%) | High volume businesses | Only makes sense at $50k+/month |
If your statement has "qualified / non-qualified" buckets, you are on tiered pricing. This model consistently extracts the most money from businesses. Switch to interchange-plus. Helcim and PaymentDepot both offer it with no contract.
Hidden fees that double your real rate
| Fee | Typical charge | What it is |
|---|---|---|
| PCI non-compliance | $15–40/month | Charged if you haven't completed annual PCI self-assessment questionnaire |
| Monthly minimum | $15–25/month | If processing fees don't hit a threshold, you pay the difference |
| Batch fee | $0.10–0.35/day | Charged every time you settle the day's transactions |
| Statement fee | $5–15/month | For receiving a statement by mail or PDF |
| Gateway fee | $10–30/month | Charged by payment gateway if separate from your processor |
| Annual fee | $75–150/year | Just for being a customer |
| Early termination | $200–600+ | Breaking a multi-year contract early |
| Chargeback fee | $15–35/incident | Charged even if you win the dispute |
A business paying an advertised 2.5% rate can easily be paying 3.2–3.8% effective rate after these fees are included.
Provider comparison for San Diego businesses
| Provider | Pricing model | In-person rate | Monthly fees | Contract |

| Helcim | Interchange-plus | IC + 0.15–0.40% | $0 | None |
| PaymentDepot | Subscription + IC | IC + 0% | $59–119/mo | None |

Helcim is consistently the best interchange-plus option for small-medium businesses. No monthly fees, no contracts, interchange-plus pricing with volume discounts that kick in automatically.
⚡ Solana USDC — When Card Fees Become Optional
For B2B transactions, recurring clients, or any customer willing to pay by stablecoin, card rates are optional. USDC on Solana is a dollar — 1 USDC = $1.00 — with network fees of ~$0.00025 per transaction.
Not every customer will use USDC. But if 30% of your volume can be moved to USDC with a small discount incentive, you're still saving thousands per year. Combine with ACH for customers who prefer bank transfer, and reserve card acceptance for walk-ins and one-time customers.
How to negotiate or switch processors
- Pull your last 3 months of statements — calculate your effective rate (total fees ÷ total volume)
- Get competing quotes from Helcim and PaymentDepot using that same volume mix
- Take the better quote back to your current processor and ask for a rate match — they often will
- If switching: check your contract for early termination fees. Many processors will waive them if you threaten to leave
- Never sign a multi-year processing contract unless offered a significantly better rate (and even then, caps at 3 years max)

What is a good merchant services processing rate?
Card-present: 1.5–2.0% is good on interchange-plus pricing. Flat-rate under 2.7% is reasonable for low volume. If your effective rate (total fees ÷ total volume) is above 3%, you're overpaying.
What are the hidden fees in merchant services?
PCI non-compliance ($15–40/mo), monthly minimum, batch fees, statement fees, gateway fees, annual fees, early termination fees. Together they can add 0.5–1.5% to your effective rate above the advertised percentage.
Is interchange-plus better than flat-rate?
Usually yes at $10k+/month. Flat-rate overpays on debit card transactions. Interchange-plus passes the actual card network cost through — typically lower on debit, slightly higher on premium rewards cards but more transparent overall.
