What's a fair credit card processing rate for a small business?

2.5–2.9% + $0.30 per transaction is typical for flat-rate pricing. If you process over $10k/month, interchange-plus pricing usually gets you to 2.0–2.5% effective. Above 3.5% on flat-rate, you're overpaying and should get competing quotes.

Can I negotiate my payment processing fees?

Yes — especially if you process over $5–10k/month. Come to the conversation with 3 months of statements and a competitor quote. Ask specifically for interchange-plus pricing, waived monthly fees, and a month-to-month contract. Most processors have room to move.

What's the difference between Square, Stripe, and traditional merchant accounts?

Square and Stripe are flat-rate, easy to start, and slightly higher cost. Traditional merchant accounts (through banks or ISOs) are cheaper at high volume but have monthly fees, multi-year contracts, and slow setup. For under $20k/month, Square or Stripe usually wins on simplicity.

Switching Costs to Consider

Migration effort: Data export formats, API parity, downtime risk
Team learning curve: How long before the new tool is faster than the old one
Contract/lock-in: Annual commitments, data portability clauses
Hidden fees: Per-seat, per-transaction, or overage charges at scale

Questions to Ask Before You Decide

What specific problem are you solving — is this a current pain or future-proofing?
Does your team have the capacity to migrate and test properly?
What happens if it doesn't work — is there a rollback plan?
