I run an online woocommerce shop in a sub domain and sell services on my main domain, and there’s no problem on having both checkouts working on my Quaderno account. They helped me configure everything with ultra fast support, have reliable integrations, any tax issue managed on-the-go, seamless billing for your customers...it’s a bargain, everything is sorted out! Congratulations for having such a wonderful, updated & well done product!!

Un plugin muy efectivo para conectar Quaderno con WooCommerce y no tener que preocuparse más por la facturación. Además, se actualiza a menudo. Recomiendo la combinación 🙂

It's a useful plugin and service. The support is excellent. The service sometimes has problems (e.g. not applying the right VAT for a few days ending up dozens of invoicing mistakes exported to Xero - a lot of manual work to fix). There's a severe incompatibility with WooCommerce's Subscription module: when you use your WooCommerce with VAT inclusive prices, the VAT calculation is wrong as soon as a subscriber manually renews his/her subscription (e.g. after a failed automatic charge). The Quaderno support is constructive with it, and the WooCommerce Subscription plugin developers are said to work on it, but this has been reported for months now without a result).
