How to add a client

A private person or a company with a tax ID: where to add a client, which fields matter and how to fetch company details from the GUS register in one click.

Nitro Serwis is in Polish. The screenshots show the Polish interface; each label is quoted in bold, with its meaning in brackets.

A client in Nitro is the person or company you do orders for: their details go on the invoice or receipt, and next time you find them by name, phone or tax ID. There is no separate “private person” or “company” choice. A company is simply a client with a tax ID (NIP).

Where to add a client

• From the clients list: Klienci (Clients) → Nowy klient (New client). On a computer the button is in the top right corner, on the phone at the bottom of the list.
• From a new order: + Dodaj nowego klienta (Add a new client) under the search field. After saving, you return to the order with that client already picked (see the vehicle intake guide).
• From the dashboard on a computer: the Nowy klient (New client) button.

What to fill in

Only Nazwa (Name) is required (the client’s name). Fill in the rest if you know it:

• Telefon (Phone) and Telefon dodatkowy (Second phone): you can search for the client by these too;
• E-mail;
• Firma / NIP (Company / tax ID): for companies, see below;
• Adres (Address): street, city and postcode, needed for invoices (company admins see these fields).

Company clients: details from GUS

Enter the tax ID (NIP) in Firma / NIP (Company / tax ID) and click the download icon next to it (Pobierz dane firmy (Fetch company details)). Nitro fetches the company name and address from the Polish GUS register and fills them in for you. If the register doesn’t know the number, you’ll see “Nie znaleziono firmy o podanym numerze NIP” (no company found for this tax ID). Check the number or type the details by hand.

A client from outside Poland? Tick Klient zagraniczny (poza Polską) (Foreign client (outside Poland)) and choose the type of tax number and the country.

With a vehicle straight away

When adding a client from the clients list, you can add their car straight away: switch on Dodaj pojazd (Add vehicle) under the form and enter the VIN. Nitro recognises the make and model. Finally, click Zapisz klienta (Save client). Filling in the vehicle is covered in the article on adding a vehicle.
