About this app

Firmbit is a complete program for running a small construction and installation company—for electricians, plumbers, fitters, and any professional working on their own. It's not just for phones: it's a complete system that also works on your computer (firmbit.pl), and the app puts everything at your fingertips on the jobsite.

PAPERWORKS ARE MADE FOR YOU
• Invoices ready for the mandatory KSeF (Key Tax Return) – you issue them yourself, Firmbit sends them to KSeF (the number and UPO are saved with the invoice)
• JPK-VAT in two clicks – a file ready for sending to the office
• Costs without retyping: download the wholesale invoice directly from KSeF or scan the QR code from the printout
• Recurring invoices, corrections, advance payments, and email PDFs to the client

YOU KNOW HOW MUCH YOU'RE REALLY EARNING
• Profit from each job is calculated automatically: the amount for the job minus materials, warehouse, and labor
• You see how much to contribute to ZUS, VAT, and PIT – no surprises at settlement
• Monthly and yearly finances: revenue, costs, net – for the entire company or separately for each business

COMPANY UNDER CONTROL
• Jobs with a work calendar, statuses, and history
• Customer database – retrieve company data by NIP (Tax Identification Number) With the Central Statistical Office (GUS) in one click
• Customer quotes that you convert into orders in one click
• Materials warehouse with order release
• Crew: employee accounts, work hours, labor settlement

Electricians, plumbers, construction workers, assembly workers, service technicians – solopreneurs or multi-person teams.
