The MemberPress Quaderno add-on is a tax automation integration designed to help membership site owners handle global sales tax, VAT, and GST compliance automatically.
This is EXACTLY the same product as distributed by the developer. Sales Page
Core Specifications & Features
The integration acts as a bridge between your WordPress membership site and the Quaderno tax engine.
-
Real-Time Tax Calculation: Automatically calculates the correct tax rate at checkout based on the member’s address and your tax jurisdictions.
-
Automatic Invoicing: Generates and sends tax-compliant PDF invoices to members immediately after a successful payment.
-
VAT Number Validation: If enabled, it allows EU-based businesses to collect and validate VAT numbers during registration for B2B tax exemptions.
-
Advanced Product Mapping: Allows you to override global tax settings for specific memberships (e.g., setting a “Digital Service” tax code for one plan and an “eBook” code for another).
-
Tax Jurisdiction Support: Syncs with your Quaderno account to apply specific rules for US Sales Tax, EU VAT, UK VAT, and others.
-
Comprehensive Reporting: Records all transactions within the Quaderno dashboard for easy tax filing and financial auditing.
Technical Requirements
To use the Quaderno add-on, your setup must meet the following criteria:
| Requirement | Specification |
| MemberPress Plan | Requires Growth or Scale plans (not available on the Launch plan). |
| WordPress Version | Current stable version (MemberPress typically follows WP core updates). |
| Quaderno Account | An active Quaderno subscription is required. |
| SSL Certificate | Required (HTTPS) to securely transmit data between your site and Quaderno’s API. |
| API Connectivity | Requires a valid Quaderno API Key and API URL (found in your Quaderno account settings). |
Configuration Details
Once the add-on is installed, it adds specific controls to your MemberPress settings:
-
Tax Toggle: Found under
MemberPress > Settings > Taxes. You must check “Enable Tax Calculations” and “Enable Quaderno.” -
Price Handling: You can choose whether your membership prices are Inclusive (tax is included in the price) or Exclusive (tax is added on top of the price).
-
Per-Membership Overrides: Under the “Advanced” tab of any individual Membership, you can specify:
-
Product Type: (e.g., Good vs. Service)
-
Tax Code: (e.g., SaaS, eBook, Consulting, or Standard)
-
Why Use It?
While MemberPress has basic built-in tax tools, Quaderno is specifically for businesses selling internationally. It eliminates the “manual” part of tax law—such as keeping track of changing VAT rates in 27+ different EU countries or varying state nexus rules in the US—ensuring you don’t accidentally under-collect or over-collect tax.
