The verdict
For a company with subscriptions, several plans, usage charges or quotes for larger customers, I'd pick Chargebee. Pricing logic stops fitting in a bank app very quickly. If you are a freelancer or sole trader who wants a separate account and an easy way to send a payment link, I'd pick Revolut Pro.
If you are somewhere in between, a small company with a few flat plans, neither is the obvious answer. Chargebee will be more than you need, and Revolut Pro is built for people without a registered company. Look at a simpler billing tool or a business account for companies instead.
