Send invoice for SMS credits

Would be super helpful if we could receive automatic invoices by email every time we're billed for refilling SMS credits, for tax/ accounting purposes.

Surprised this is not yet an option - as it stands my book keeper has to message me every time there is a random charge from Ontraport, and I have to log in, go to the admin settings, manually download an invoice for SMS credits, and email it to her, creating a lot of unnecessary admin.

I receive monthly email invoices for Ontraport, and would love if this feature could also cover other charges, eg SMS credits. Spoke to support about this and they suggested I submit a feature request. Thanks for your help.
