Cash doesn't really exist in the payments stack for an online business. Credit card chargebacks can roll in months after a compute instance is closed down and companies like Google have little recourse here.

"Just take cash" isn't an option.

I know AWS does, or did, take wire transfers for payment.

Those are much harder to claw back, particularly if you have a signed agreement from the customer saying "We want to pre-pay for $50k in compute resources. We understand that once the pre-paid amount is used, it cannot be refunded."

I'm sure GCP and any other legitimate cloud provider could also take wire transfers for sizable payments, without issue.
