Brik is invoicing for Nigerian small businesses that get paid by bank transfer. Create an invoice, send it as a link or a PDF, and record the payment when the money lands. Your receipts, expenses and revenue sit in one place, so you can answer "who still owes me" without reading down a bank statement. WHAT YOU CAN DO • Create and send an invoice from your phone, by link or PDF • Show your own bank account on every invoice, or take card payments through Paystack • Record a payment and Brik issues the receipt • Track expenses, so the figure you are looking at is profit and not just revenue • Send reminders on overdue invoices instead of remembering to chase them • Export your records to CSV whenever you want WHY BANK TRANSFER COMES FIRST Most business payments in Nigeria move by transfer, so Brik treats that as the normal case rather than an afterthought. Your account details sit on the invoice itself. Paystack is there if a customer would rather pay by card, and you are not tied to either one. WHO USES IT Landlords and agents bill rent, service charges and agency fees, and keep a record of who has paid. Consultants, tradespeople and retailers use the same screens for ordinary invoicing. YOUR DATA You can export your records at any time. You can also delete your account and your personal data from inside the app, without emailing anyone to ask. The free plan covers 10 invoices a month.
