Testing sale subscription for generating invoice?

Support User

hello guys

i want to generate a maintenance invoice every 3 months . is it possible how could i test it for small amount of time like every 5 minute ?

Yes, you just have to use an invoice recurrence of three months.

Not sure to understand what you need.
But if you want to test that the subscription recurrence works you just need to use the invoice wizards with a date in the future.

can you tell me how can i run invoice wizard ? seems i can’t find the option to run it ?

is that the wizard option ?

You should first create the consumptions and then the invoices.

It seems you have a consumtion without quantity and this breaks the invoice quantity.

Could you please fill a bug with the steps to reproduce it on a fresh database? Thanks in advance
