We use ChargeBee for our SaaS product. Really great offering! They give you a customer portal where the customer can cancel, update, upgrade, ... his subscription. We have a custom checkout page where all options are listed. Then one API call and the user is forwarded and can fill out billing address, payment information, etc. on a ChargeBee page. They will handle taxes, issue invoice and everything else for you.

They have also an extensive API and webhooks.

Thank you @foxylion and @homero for mentioning Chargebee.

Krish, Cofounder of Chargebee here. A lot of our customers use Stripe + Chargebee combination as we complement them by leveraging the best features of Stripe. We like the way Stripe.Js, radar and auto card updater etc is beautifully built. (ex: you can pass Stripe token to create a subscription in Chargebee). We continue to build in a way that we let you use those features while providing a full fledged billing system that integrates all the way from CRM, helpdesk /intercom to accounting. Your finance or sales can collect non card, PayPal payments without any changes to the code. Enabling those business users post implementation with support is our core value prop, so that developers don't have to worry about giving internal solutions afterwards.

Give it a spin and for the idea launch stage we have a freemium tier for first $50k usd. If you have any feedback please write to me at Krish at Chargebee.

Stripe just does the processing. But for SaaS, you really need something like https://bullettrain.co/. It does pricing pages, subscription and user management (which is what takes most of the time to implement).

It does a lot of the heavy lifting for credit cards, but is nowhere near a full billing system for SaaS. It’s why things like Churnbuster and BareMetrics exist. About 20% of our customers need to pay with something other than a CC, which complicates billing even further.

Unless you have a low cost SaaS product (monthly credit card billing) Stripe is a pain. If you have anything resembling an enterprise sales process juggling dozens of invoices, discounts, payment terms, etc., becomes a hassle.

Is there an Enterprise Sales ready billing / invoicing solution? We're using Quickbooks - it leaves much to be desired.

Yes, but they require integration, which is no small feat. You'll have to wrap their fairly low-level payment processing services into your own business logic.

So, it's far from flipping a switch. There is Webhook integration, state management, notifying users, etc.

That is not Enterprise saas in my experience. That is someone signing up for a 20-100 dollar a month service. A 40k a year contract is a bit different

Yep but if you want to support other payment types, such as paypal then you need to deal with that too.

Suddenly you need to write payment abstractions on your back-end to handle both and most pre-written libraries that try to do this fail because they don't handle cases you may need.

That only handles the mechanics of accepting a payment too.

We use Stripe, and it's been great. But now we need to start providing invoices and charging different tax rates for different countries ... and suddenly the low-level processing of Stripe just isn't enough.
