I created an invoicing native application, with Electron front-end, Golang backend, and Firebase DB. Users can enter inventory items, customer profiles and payment histories, the invoice data, and download/print the invoice as PDF. With its offline capability, their data are saved dirty in the device local disk and synced to the online DB as soon as a connection is detected.
For a full overview, you could checkout this reflection post of the first version from August 2020, and another post of the second version update.
Also note that the content of the app is Indonesian.
