What’s new in MemberPress Quaderno 1.1.0

What it does
Selling memberships across regions means dealing with different tax rules for each customer. Entering rates by hand is slow and easy to get wrong, especially when you sell digital products, services and subscriptions to buyers in many countries. This add-on removes manual rate entry by handing tax calculation to Quaderno. When a customer registers and pays, the correct tax is worked out from their address and the tax jurisdictions you have set up, then applied to the purchase.
The work does not stop at checkout. Sales, tax and customer details are sent back to Quaderno, where you can manage invoices, view sales reports and keep tax documentation in one place. You can also decide whether prices include tax or show it separately, and set tax codes per membership with product types such as consulting, SaaS or eBooks. It suits membership businesses that already run on MemberPress and want tax handling tied directly to their transactions.
Best for
- MemberPress sites selling memberships to international customers
- Creators selling eBooks, courses or digital subscriptions
- SaaS and consulting businesses using MemberPress for billing
