Overview
Selling memberships to customers in different regions means dealing with different tax rules. Entering rates by hand takes time and is easy to get wrong. MemberPress Quaderno hands that job to Quaderno. When a customer registers and buys, the add-on applies the tax that fits the customer's address and the tax jurisdictions you have set up.
The data does not stop at checkout. Sales, tax and customer details are sent to Quaderno, where you can manage invoices, read sales reports and keep tax documentation. It suits sites that sell digital products, services or subscriptions. The add-on is meant for MemberPress Pro plan users, and you can adjust tax treatment for each membership.
Features
- Quaderno connection: Links your MemberPress site to Quaderno's tax automation software, so you no longer need to enter tax rates manually for each sale.
- Tax by customer location: Calculates the tax rate from the customer's address, applying sales tax, VAT or GST according to regional rules.
- Custom tax jurisdictions: Create and manage tax jurisdictions in Quaderno to cover multiple regions, with the relevant taxes applied automatically for each one.
- Inclusive or exclusive tax display: Choose whether prices are shown with tax included or added on top, to match your business model and what customers expect.
- Per-membership tax codes: Override the default tax settings on each membership with product types such as consulting, SaaS or eBooks, so every product is taxed appropriately.
- Automatic data sync: Sales, tax and customer details are sent to Quaderno automatically, which supports invoicing, sales reports and tax documentation.
- Setup with API keys: Configure the connection to Quaderno from the WordPress dashboard using API keys, so the tax automation can start running.
Best for
- Membership sites selling to customers in several countries
- Sellers of digital products, services or subscriptions
