Most business owners look at their transaction rate and stop there. They see "2.95%" and think they understand what they're paying. That's exactly what payment processors are counting on.

The headline rate is just the beginning. Underneath it is a collection of smaller charges, some clearly labelled, most not, that quietly add up every single month. I've sat down with enough payment statements to know that the actual cost is almost always higher than what the business owner thinks they're paying.

Here are the eight most common hidden fees, what they're typically called on your statement, and what they cost SA businesses.

01

Monthly minimum fee

R199 – R399/month

If your card turnover drops below a threshold set by your provider, usually around R5,000 to R10,000 in monthly transactions, you pay this regardless of what you actually processed. It's the provider's way of guaranteeing minimum revenue from your account. Slow January after the December rush? Quiet patch during school holidays when foot traffic dried up? You're paying whether you traded or not.

02

PCI DSS compliance fee

R99 – R249/month

PCI DSS is the Payment Card Industry Data Security Standard, the set of security rules that any business handling card payments must comply with. Almost every payment provider charges a monthly fee for this. It covers their certification costs and security infrastructure. The problem is it's often buried on statements as "PCI compliance," "security fee," or "compliance management fee." Most business owners assume it's just a normal part of the transaction fee. It isn't, it's extra.

03

Chargeback handling fee

R250 – R450 per dispute

When a customer disputes a transaction with their bank, that dispute comes back to you as a "chargeback." You have to respond with evidence, the receipt, proof of delivery, whatever applies. The fee kicks in the moment a dispute is opened. You pay it to have the dispute processed, even if you win, and even if the dispute turns out to be fraudulent. A busier retail store in Sandton or a restaurant in the V&A Waterfront might see two or three of these a month, easy.

04

Early termination / exit penalty

R1,500 – R5,000

This one stings when you find it after the fact. Many POS and payment providers lock you into 12 or 24-month contracts. If you want to leave before the term is up, because you found a better deal, or because you're closing, or because the service isn't working for you, you pay a penalty. Some providers calculate this as a percentage of what you would have paid for the rest of the contract. Read the agreement before you sign, not after.

05

Terminal rental / hardware fee

R199 – R499/month

The card machine sitting on your counter, do you actually own it, or are you renting it? A lot of businesses don't know the answer to this question. Many providers offer "free" hardware that turns out to be a rental, charged monthly for as long as you're with them. Over 24 months, that "free" device has cost you R4,800 to R11,976. You also can't take it with you if you switch providers.

06

Monthly statement / account fee

R75 – R150/month

This is a charge just for the privilege of receiving your own transaction data. It shows up as "account fee," "statement fee," or sometimes "admin fee." It exists because it can. There's no legitimate reason why accessing your own payment history should cost you R75 to R150 a month, but providers include it because most people don't notice it on a busy statement.

07

International card surcharge

Extra 1 – 2% per transaction

If you run a business in a tourism-heavy area, the Cape Winelands, Camps Bay, a hotel in the Garden Route, a game lodge in Limpopo, pay close attention to this one. Transactions on international Visa or Mastercard cards often attract an additional rate on top of your standard domestic rate. Some providers are transparent about this. Others bury it. If 20% of your turnover comes from foreign tourists, an extra 1.5% on those transactions adds up fast.

08

Integration / API access fee

R299 – R999/month

Trying to connect your payment processor to your accounting software, Xero, Sage, QuickBooks? Or sync it with your inventory system? Some providers charge a separate monthly fee for API access or for enabling third-party integrations. It's positioned as a "premium feature," but it's really a basic expectation in 2026. If your POS system charges you extra just to talk to your other tools, that's worth factoring into your total cost.

Add it up: Take just the first four fees, a monthly minimum (R299), PCI compliance (R180), two chargebacks at R350 each (R700), and a hardware rental (R349), and you're already looking at R1,528 before a single transaction is processed. That's on top of whatever percentage you're paying on your card turnover.

How to audit your own statements

This takes about 20 minutes and is worth doing once a quarter.

  1. Download your last three months of payment processor statements, not your bank statements, the actual statements from your payment provider or POS company.
  2. Go through every line item. Highlight anything that isn't your standard transaction fee. Write down the amount and what it's labelled as.
  3. Add up all those extra charges across the three months and divide by three. That's your average monthly non-transaction cost.
  4. Now add your average monthly transaction fees. This gives you your true total monthly payment cost.
  5. Divide the total by your monthly card turnover. That's your effective rate, the real percentage you're paying, not the headline number.

For most businesses I speak to, the effective rate comes out 0.3% to 0.8% higher than their quoted transaction rate once all the extras are included. On R200,000/month in turnover, that's R600 to R1,600 in fees they hadn't accounted for.

What Nexo charges

I'll be straightforward about our own pricing, because that's the whole point of writing this.

Nexo charges R499/month (NEXO Plan) or R750/month (PRO Plan). That's it. The monthly fee covers the software, the support, and the infrastructure.

Transaction fees are quoted clearly upfront, approximately 1% on debit card transactions, which account for the majority of SA card payments. There are no monthly minimums. No chargeback admin fees charged back to you. No PCI line items on your statement. No separate API fees to connect your accounting software.

We charge what we charge, we tell you what it is, and that's what you pay.

Not every provider has eight hidden fees. Some are cleaner than others. But if you've never sat down and added up every line item on your payment statements, there's a reasonable chance you're paying more than you think. Pull up those statements this week. The number might change how you think about your payment setup.
