How to choose

Which billing needs should it cover?

Choose software that matches your billing models and handles proration, the adjustment made when a subscription changes before its billing period ends.

Check the board's comparisons for dunning workflows, which are steps for following up on failed payments, and for tax handling.

Which payment gateways does it need?

Confirm that the software supports the payment gateways your business uses.

Can it handle subscription migration?

Check the migration details before choosing a tool if you need to move existing subscriptions.

Do you need a public API or self-hosting?

Check the API and platform marks if you need software to connect with other systems or run on your own infrastructure. The platform options listed include web, API, and self-hosted.

An API is a way for software systems to exchange information. Verify that its available options fit your setup.

What will it cost to get started?

Compare the free-plan mark with the stated starting price and trial terms. Pricing can be on request, so contact the maker when the board does not give a price.
