Here at Cloud Stop Motion we offer the ability to upgrade via Purchase Order alongside the option to pay online by card.
As you go through the process to upgrade your storage allowance you can switch payment methods at checkout. This will provide your account with immediate access to the increased storage allowance and Premium Animation Features, while an invoice is emailed to your billing email address as provided. The invoice email contains a payment link ready for online payment by your finance team, or our bank details can be found on the actual invoice when settlement by ACH payment is preferred.
Quick tip - just be sure you are logged in on the educational / organization account when you upgrade so you do not accidentally upgrade a personal account instead!
