Frequently Asked Questions

How does the VAT Rates module work?

The module connects to authoritative tax data sources — including the EU Commission’s official VAT rates and US state sales tax registries — and automatically imports or updates the tax rates inside your Perfex CRM configuration. You set the sync schedule, and the module handles the rest without any manual data entry.

Which tax jurisdictions does the module support?

The module supports VAT rates for all EU member states as well as sales tax rates for US states. This covers the most common invoicing scenarios for freelancers and agencies working with international clients.

Is this module compatible with my version of Perfex CRM?

The module is built for Perfex CRM and follows the standard module architecture. It is compatible with current Perfex CRM versions. If you run an older installation, contact support before purchasing and we will confirm compatibility.

How difficult is the installation?

Installation follows the standard Perfex CRM module upload process: download the ZIP, upload it via the Modules section in your admin panel, and activate. No code changes or server access are required.

What happens to my existing tax rates after the first sync?

The module updates existing rates and adds missing ones based on the imported data. It does not delete custom rates you have manually configured. You retain full control and can review all changes in your Perfex CRM tax settings after each sync.

Do I need a subscription or annual renewal to keep using it?

No. This is a one-time purchase with lifetime usage rights. You pay once and continue using the module indefinitely, including all future updates covered under the purchase.

What kind of support is included?

Purchase includes email support for installation issues and bug reports. Response times are typically within one to two business days. If you have a pre-purchase question, you can reach out before buying and will receive a straight answer.

What if the module does not work for my setup?

Contact support with a description of your environment and the issue. Edge cases and compatibility problems are handled on a case-by-case basis. We stand behind the functionality described on this page and will work with you to resolve any problems.
