The brief
An internal web tool to charge the firm's clients monthly fees that start and end on a set date, without creating each payment by hand.
What I built
It is a single screen: you create a fee on the left and see all of them, with their status, on the right.
- To set up a fee you only need the name, email, monthly amount, and start and end dates. The panel creates the subscription in the payment gateway and the client receives the payment link by email, SMS or WhatsApp.
- The subscription ends by itself on the end date. If it starts later, nothing is charged until that day.
- If a payment fails, it is retried automatically.
- Each fee's status (pending, active or cancelled) updates itself from the gateway's notifications.
A search of its own
Type part of the name, email, phone number or ID and the client's fee appears, with its status and dates.
What changed for the firm
Fees are no longer created or collected by hand: each one is set up once, with its start and end dates, and every month's charge goes out on its own. If a charge fails it is retried without anyone having to notice, and the status of each fee updates from the payment gateway's notifications. When a subscription reaches its end date it stops by itself. Finding a fee takes typing part of the client's name or email.
The contract with the firm does not allow publishing figures about its business, so this case describes the work and not its results.
After delivery
I host it on a private server, with backups, monitoring and up-to-date certificates.
