Who it's for

Solo builder or 2-person team targeting African freelancers (designers, writers, developers, consultants) who invoice in USD but live in Nigeria

How to build it

1. Build a clean invoice generator that auto-converts NGN to USD rates daily and lets users send branded invoices via email or shareable link 2. Add a payment tracking dashboard showing which clients have paid, which are overdue, and send one automatic reminder email per invoice 3. Integrate Stripe or Flutterwave so clients can pay directly from invoice (you take 2–3% + payment processor fee) 4. Add a simple analytics view: total billed this month, average days to payment, client list with payment status 5. Offer tiered pricing: free tier (5 invoices/month, no payments), Pro ($5/mo, unlimited invoices + payment collection)

Flutterwave integration also lets local clients pay in NGN while you colle
