Invoicing for Nigerian businesses.
Brik is an invoicing app for Nigerian businesses. Send neat invoices, get paid through Paystack, keep track of your clients, and make sure every payment matches your records. It works on web and phone, and fits how Nigerian businesses really get paid.

Many Nigerian businesses send invoices on WhatsApp and track payments with screenshots. Money comes in split across banks, transfers and cash. Most invoicing apps assume everyone pays with one simple card tap.
Brik handles Paystack payments, gives each invoice a link people can pay from, works on both web and phone, and matches the way Nigerian businesses actually get paid.
