How It Works

Go from unpaid ledger invoices to settled cash flow in three automated steps.

1

Connect Xero or Sage SA

During your pilot we connect your Xero or Sage Business Cloud Accounting South Africa organisation with you. KassaFlow syncs open invoices, due dates, and customer contact details automatically.

2

Polite WhatsApp Utility Reminders

KassaFlow sends polite, branded WhatsApp Utility reminders before and after due dates. Customers can reply STOP at any time to opt out.

3

1-Click Pay Now & Auto-Reconcile

Customers tap Pay Now to pay via Ozow Instant EFT or Paystack. Once confirmed by webhook, KassaFlow records the payment against the invoice in Xero or Sage SA automatically.

Built for South African SMEs

Designed around local payment rails, Rand billing, and strict merchant controls.

Transparent ZAR Pricing

Predictable monthly Rand (ZAR) plans tailored for South African businesses and accounting practices, with no foreign currency surprises.

Native Paystack & Ozow Instant EFT

Give B2B buyers the payment methods they already trust in South Africa — Instant EFT via Ozow or card/EFT checkout via Paystack.

You Stay in Control

Customers can tap “Query invoice” to pause reminders and alert you, or “I’ve already paid” to pause them for 48 hours. Contact exclusions and a dry-run mode are coming soon.

POPIA-Aligned Data Handling

Built for the Protection of Personal Information Act (POPIA): accounting and gateway credentials are encrypted at rest, and debtor opt-outs (STOP) are honoured immediately.
