    Wasooli serves recurring-billing businesses - gyms, schools, internet providers, water suppliers, housing communities, hostels, salons and rental properties - that used to prepare invoices by hand and chase payments by phone.

    It automates the whole monthly cycle: invoices are generated and delivered on WhatsApp in two languages, customers pay through bank-app and wallet payment networks, and each customer's ledger updates automatically when money arrives.

    What it does

    The modules, end to end.

    Automated monthly billing

    Invoices generated on schedule and delivered on WhatsApp in two languages.

    Digital payment collection

    Payments through bank payment networks and mobile wallets, reconciled automatically.

    Self-updating ledgers

    Each customer's ledger updates the moment a payment is received.

    WhatsApp team inbox + AI

    A shared WhatsApp inbox with an AI assistant to help staff answer faster.

    Attendance & access

    Biometric attendance and door access for gyms, plus staff attendance, salaries and expenses.

    Customer app & owner dashboard

    Customers view and pay bills in a mobile app; owners see collections and performance in one dashboard.

    Engineering notes

    The hard parts, and how we handled them.

    WhatsApp at the center

    Billing, reminders and support all run through WhatsApp, which means template management, delivery handling and a shared inbox had to be first-class features.

    Payments that reconcile themselves

    Payment-network integrations feed straight into ledgers, removing the manual matching that eats staff time.

    Hardware in the loop

    Biometric attendance and door-access devices connect to the same member records as billing.
