7. What is an e-invoice?
An e-invoice is a legally valid method of billing. It is an invoice that is delivered to you electronically in lieu of the traditional paper document.
E-invoices issued by T-Mobile Polska are securely signed using a digital certificate from PWPW SA (Sigillum Certification Centre). E-invoicing is available to all T-Mobile Polska Customers. Each e-invoice issued is sent to the e-mail address you specify. You can verify that the document is genuine and was issued by T-Mobile Polska at http://www.itbcg.pl.
- No paper bills – less money spent on archiving and a reduced environmental footprint
- Eliminated risk of document loss, which is of particular importance in the context of the taxpayer's obligation to ensure availability of invoices to tax authorities
- No risk of the invoice delivery failure or its disclosure to unauthorised parties
- Invoices always arrive on time. Timely delivery and no delays that sometimes can happen to paper documents.
- You can plan your expenditures well in advance, as the electronic invoice will reach you sooner than a paper one.
- You still can print the e-invoice on your own (e.g. for the purposes of approval processes within your organisation)
E-invoice can be collected from anywhere, all you need to download it is Internet access.

If you wish to receive electronic invoices, please complete and sign the e-invoicing consent form and send it by traditional mail to:

E-invoices are delivered free of charge. Our e-invoicing solution does not impose any additional costs on our Customers and does not require you to use any additional dedicated software. All you need to be able to benefit from e-invoicing is:
