Aplikacja Podatnika KSeF and Komplet
The Ministry of Finance’s app is the official, free way to issue and receive e-invoices in KSeF, and it runs in any browser, Mac included. If you send a few invoices a month and need nothing else, it may well be enough. Komplet looks after the rest of the month: it reads your cost invoices and bank statements, matches payments and prepares the month for your accountant; with Connect it also sends and receives KSeF invoices from your Mac. Neither of them keeps the books.
Komplet is not another accounting service. Its core job is gathering your documents, invoices, receipts and statements, and preparing them for whichever tool or accountant keeps your books. Easy to use, friendly, updated often, and made by entrepreneurs for entrepreneurs.
