Awesome plugin and awesome support

I’ve been the worst client asking a ton of question before even purchasing the service. Support was very helpful, they resolved a couple of bugs I found in no time.

If you are hesitating and thinking if this is for you – don’t do my mistake. I should’ve gone for Quaderno the day I start my shop and I’d certainly save a lot o headache!

A must have plugin for EDD

Switched from Taxamo to Quaderno to make our site compliant with EU Tax laws as the Quaderno integration with EDD is so much better than Taxamo. Definitely recommend using Quaderno if you sell to EU customers.

Support is very responsive as well!

Thanks for making it easy to be tax compliant!


For me Quaderno right now is the best solution for automated tax and invoice handling when using Easy Digital Downloads. So happy I finally moved over to Quaderno!

An essential plugin for EDD

After six months of research and testing I couldn’t find any other way to comply 100% with all the EU regulations. By implementing Quaderno I was able to get everything working perfectly and in the process remove 3 other premium plugins from different developers. Most importantly, the team at Quaderno is very knowledgeable and extremely helpful.

I’ve found it’s fully compatible with all the EDD extensions I have installed including Recurring Payments, Software Licensing and Stripe and PayPal gateways.

The best option for invoices in UE

Thanks to Quaderno I can have a fully automated billing system with Easy Digital Downloads in my WordPress website.

I save a lot of time in the monthly billing, including European tax problems.

Now I can focus on my business, because it’s what interests me.

Thanks very much Quaderno!
