InvoiceManager
Invoices, offers and dunning for small businesses.
What it does
InvoiceManager is an invoicing platform for small businesses and freelancers. Write offers and invoices, pull line items from a catalogue, generate a PDF with a Swiss QR-bill and send it straight from the application.
You can run it yourself. The whole stack starts with a single Docker Compose command.
