Membership businesses live and die by collections and retention. The operational drag is familiar: invoices sent by hand, reminders that depend on someone remembering, failed payments noticed weeks later, and attendance tracked on paper.
Our team built Wasooli, a platform for recurring-billing businesses that automates monthly invoicing, sends reminders on WhatsApp, collects payments digitally and updates each customer's ledger automatically - with attendance and door access for gyms and a customer app. We bring that experience to custom systems and integrations for US businesses.
Where the time and money leak.
Manual monthly billing
Invoices prepared by hand every cycle, with errors and late sends.
Failed and late payments
Card declines and unpaid invoices noticed too late, and awkward chasing by staff.
Reminders nobody sends
Renewals, class changes and payment reminders depend on someone's memory.
Attendance and access
Check-ins, staff attendance and door access tracked separately from billing.
Software for memberships & subscriptions teams, shaped around your workflow.
Each of these can be a focused first project. Most clients start with the one that costs them the most hours each week.
Automated recurring billing
Plans, proration, invoices and receipts generated automatically, with Stripe Billing or your processor.
Reminders with pay links
Payment and renewal reminders on WhatsApp, SMS or email with one-tap pay links.
Failed-payment recovery
Smart retries, card-update requests and staff alerts before a member churns.
Attendance & access control
Member check-in and staff attendance tied to access-control hardware through its API.
Member apps
Schedules, bookings, bills and notices in a mobile app members actually open.
Owner dashboards
Collections, churn, attendance and revenue by location in one view.
Connected to the tools you already use.

Memberships & Subscriptions software: common questions.
Should a gym build its own software?
Most single-location gyms should use an established membership platform. Custom makes sense for multi-location operators, unusual billing models, or when you need billing, access and messaging connected in ways off-the-shelf tools don't support.
Can payment reminders go out on WhatsApp?
Yes, as utility messages through the official WhatsApp Business Platform with customer opt-in. Payment and renewal reminders are exactly the kind of message the platform is designed for.
Can you integrate with our access-control system?
Usually, if it offers an API - many modern systems like Kisi and Brivo do. We confirm what's possible during discovery.
Have you built billing software before?
Yes. Our team built Wasooli, a recurring billing and collections platform with automated invoicing, WhatsApp reminders, digital payments, automatic ledgers, attendance and a customer app.
