SlimFact originated from requiring a simple, API based, way to automate payments and invoicing. It allows for easy integration into other applications by offering a tRPC API and OpenID Connect authentication. The main principles are: Immutable invoices: - Once an invoice is opened, it remains unchanged. No accidental modifications or discrepancies. - Fully rendered in the browser, eliminating the need for additional PDF generation packages. Flexible billing: - For orders that may undergo changes, SlimFact allows you to create bills. - Bills can be seamlessly converted to receipts once paid, maintaining a clear transaction history. - If the client requests an invoice, receipts can be converted to an invoice with a single click. Efficient UUID Access: - Each invoice is uniquely identified by a UUID (Universally Unique Identifier). - Clients can access their invoices anytime using their unique identifier. Payments are supported by integration of payment service providers. Website: https://www.slimfact.app Demo: https://demo.slimfact.app Github: https://github.com/simsustech/slimfact
