How Float BNPL Works with Your Existing Credit Card

Float does not give you a new credit line. It does not ask you to apply for a card. What it does is take a purchase that already landed on your Visa or Mastercard statement and restructure how you repay it. That distinction matters more than it might sound.

The Core Mechanic

When you buy something with your credit card, the full amount hits your available credit immediately. Under normal circumstances, your bank expects you to either pay it off at month end or carry it forward as revolving debt attracting interest at roughly 20 to 22% per annum. Float intercepts that second path.

After your transaction settles, you log into Float, select the purchase, and choose a repayment plan: 3, 6, 12, or up to 24 monthly instalments. Float then schedules those payments using DebiCheck-authenticated debit orders against your linked bank account. Each instalment hits on a date you confirm upfront. No surprises.

The interest-free part? That is the product. Float earns from a merchant facilitation fee, not from charging you a financing rate. So the R8,400 laptop stays R8,400 whether you pay over 3 months or 12.

What Happens to Your Credit Card

Here is the thing most people miss: Float does not reduce your credit card balance immediately. Your card still shows the full purchase amount as utilised. What Float does is take over the repayment schedule so those funds flow back to your card on time, month by month, automatically.

Think of it as a structured repayment layer sitting between you and the revolving balance trap. Your card gets restored. You stay current. No interest accrues because you are not carrying a balance in the traditional sense.

We have seen users get confused expecting their card balance to drop by the split amount the moment they activate a Float plan. It does not work that way. The card issuer, whether Absa, FNB, Standard Bank, Nedbank, or Capitec, sees normal settlement. Float handles the installment logic on its side.

Card Compatibility

Float works with any South African-issued Visa or Mastercard credit card. Amex cards are currently excluded due to network settlement timing differences. The card must be in your name and must be in good standing. We do not support business credit cards in the current beta.

The linked bank account for debit orders must be at a DebiCheck-participating bank. That covers all the major South African banks. Capitec accounts require a separate authentication step through the Capitec app. Takes about 90 seconds.

Selecting a Plan Post-Purchase

Timing is important. Purchases can be split within 30 days of the transaction date. After that window, the transaction is no longer eligible. In practice, we recommend activating a Float plan before your credit card statement closes, because once you pay the full statement balance, there is nothing left to split.

The selection flow in the Float app takes four taps: open the app, find the transaction (auto-imported from your card), choose instalment count, confirm the debit order date. That is it. The DebiCheck mandate is created in the background and your bank authenticates it via push notification.

What Float Is Not

It is worth being explicit. Float is not a payday loan. It is not a personal loan. It is not a credit facility with its own interest rate or repayment terms that compound over time. It is not a replacement for your credit card. It sits on top of your existing card relationship and improves one specific aspect of it: large purchase repayment flexibility.

Fact: the average South African credit card carries a revolving balance. The average prime-linked credit card rate as of late 2024 sits around 20.75%. On a R10,000 balance paid over 12 months at minimum payment only, you will pay approximately R2,200 in interest. Float removes that cost entirely for eligible purchases.

The Beta Programme in Cape Town

In our current Cape Town pilot, 30 users activated Float on purchases ranging from R1,200 to R28,000, with an average split of R9,300 per plan. Zero defaults. Not because we filtered for low-risk users, but because the product design aligns incentives: users who want to preserve their credit card availability are motivated to keep instalments current.

That alignment is the model. We are not betting on repayment compliance. We are structuring the product so compliance is the path of least resistance.
