  • Contact information (email, phone, address)
  • Bank account details for payments
  • Tax identification numbers
  • Paystack integration for online payments

Can I have multiple Business Profiles?

Payments & Paystack

What is Paystack integration?

Paystack is a Nigerian payment gateway that allows your customers to pay invoices online using debit cards, bank transfers, USSD, or mobile money. When you integrate Paystack, a "Pay Now" button appears on your invoices, making it easy for customers to pay instantly.

  1. Add your bank account details in your Business Profile

  4. Funds are settled by Paystack (usually T+1 or T+2 days)

Can I accept partial payments?

Yes! Khan Invoice supports partial payments. If a customer pays less than the full invoice amount, the invoice status changes to "Partially Paid" and shows the remaining balance. Customers can make multiple payments until the invoice is fully paid.
