Anyone using PayPal subscriptions and still getting asked for invoices every month?

I’m noticing something odd with PayPal subscriptions and wanted to sanity-check if it’s just me.

When customers pay via PayPal subscriptions, they get receipts. But many B2B customers still ask for proper invoice PDFs every billing cycle (for accounting, reimbursements, tax, etc.)

In my case, switching payment processors isn’t trivial, so PayPal ends up being the default. The result is a lot of manual work:

Generating invoices after payment.
Updating billing details when customers request changes.
Sending the same invoice every month.

Curious how others handle this today:

Do you just manually generate invoices?
Have you hacked something together?
Or did you eventually switch stacks because of this?

Not selling anything! Just trying to understand how common this problem actually is.
