Every company (limited liability company, general partnership, limited partnership, etc.) faces the same dilemma: how to „open the door” to the National e-Invoicing System? We have two paths. The first is the bureaucratic path through the ZAW-FA form. The second is a technological highway using a qualified electronic seal.
At podpisano.pl, we like simple solutions, so we've prepared a summary that shows in black and white why making a company's system dependent on a particular person is a risky gamble.
This is a solution in which the CEO or Proxy „manually” designates a specific person (e.g. himself or herself or an accountant) at the Tax Office to manage the company's invoices.
It's a digital equivalent to company stamp, but with legal force equal to a handwritten signature (in the context of data integrity). The certificate contains the company's data (NIP, REGON, name), not the data of John Smith.
As experts in trust services, we recommend the seal as the standard for any company. Here's why:
Verdict
ZAW-FA is a prosthesis - good for takeoff For micro-entities, where the owner does everything himself. However, if you are serious about your business, want to rest easy and not worry whether „Mrs. Basia has a valid signature”, choose a Qualified Electronic Seal. It's an investment in the security and reliability of your accounting processes.
Using an electronic seal is the fastest way to „activation” company in KSeF. You bypass office visits and the whole process takes a few minutes in front of your computer.
Remember, however, that the seal is mainly for opening doors and management - it's a good idea to authorize specific employees or IT systems for day-to-day work.
