What should we do if the supplier hasn’t started e-Invoice yet? Can we just self-bill?

No — you are not allowed to issue a self-billed e-Invoice for a supplier who has not started e-Invoice implementation.

Here’s what you should do instead until your supplier begins their e-Invoice implementation:

1. Record the expense in your system as usual, following your normal accounting process.

2. Obtain the standard supplier invoice from them (paper or PDF) as your supporting document.

Important: The responsibility for e-Invoice compliance lies with the issuer, not the recipient. Therefore, if you do not receive an e-Invoice from a supplier who is supposed to issue one, you are not at fault.
