Stripe is a card payments platform with a public API. It offers hosted or embedded checkout pages, shareable payment links, subscriptions and invoices, and it is available to businesses in Malta. You can use all of it from its dashboard, and for a handful of sales a month that is often enough.
Connecting it to your own system means your system, not a dashboard, knows who paid what and for which job. The important part is the return trip: Stripe tells your system by a signed message (a webhook) when a payment succeeds, fails or is refunded, and the system updates the booking, the invoice and the customer’s record without a person in the middle.
