I created an integration for FreeAgent, you can download the free version here: https://wordpress.org/plugins/integration-for-freeagent-woocommerce/
Would love this, as it would allow me to easily keep all of my cash flows organised in one place

Freeagent has grown significantly in the last 4 years and now has a massive user base in small businesses.
I would find this plugin to be a massive time saver!
