🧾 Hidden Fees to Watch Out For

When evaluating credit card processors, don’t just look at the advertised rates. Many small businesses are caught off guard by additional charges buried in fine print. Here are the most common ones:

1. PCI Compliance Fees

Businesses that take card payments must comply with Payment Card Industry (PCI) regulations, which can cost up to $100 per year, according to some processors.

2. Statement Fees

Some providers charge $5–$15 monthly just to send you a paper or digital statement.

3. Batch Fees

A batch fee is charged when you settle your day’s transactions. It's often small (e.g., $0.10–$0.30), but it adds up.

4. Early Termination Fees (ETFs)

Avoid processors with long-term contracts that include ETFs. If you switch providers, you might face a $250+ cancellation charge.

5. Non-Sufficient Funds or Chargeback Fees

Even if the buyer is in error, chargebacks (customer disputes) can cost you anywhere from $15 to $25 every instance.

✅ Tip: Always request a full fee schedule from your provider before signing anything.
