| Details needed | The current address, email, account number, SWIFT code and bank name, as applicable to your changes. |

Process recording

Find the correct company
Choose Settings, then Company Data. Under Your companies, check the name and TIN of the entry you want to edit.
The pencil is on the right of the row, beside the bin. The Add company form below the list is for adding another company.
Open the edit form
Click the pencil beside the correct company. The Edit company window opens with its current details.
Check Company name * and TIN *. Here, TIN contains the Polish NIP. Keep both unchanged in this example. If you selected a different company, click Cancel and open the correct entry.
Enter the current details
Update Street, Email, Postal code and City. The example uses Przykładowa 12, 00-002 Warszawa and biuro@example.test.
To update the bank details, fill in Bank account number, SWIFT code and Bank name. The form automatically converts the SWIFT code to uppercase. Keep correct values in fields you do not need to change.
Compare the whole form with your details before saving. Cancel closes the window without saving changes.
Save the form
Click Save. After a successful response, the Edit company window closes.
Your companies should show the new address and bank details. The name and TIN stay the same in this example. The email is not displayed in the list row.
Final state
Check the result
Reload the page and, in Company Data, click the pencil beside the same company again. Compare the saved address, Email and bank details.
If the values are correct, close the window with Cancel. Opening the form just to check it does not require another save.
