At Welgo, you will receive your invoice each month on the anniversary date of your delivery.
For example, if your delivery was on the 20th, you will receive your invoice on the 20th of each month.
You can view the history of all your invoices directly from the WELGO app.
To do so, log into your account, then click on "My account" and then on "Payment methods." You will have an overview of your invoices and can download them if needed.
