My organisation is looking at integrating Zoho Books/CRM with our Sage 50 (UK) accounting. I've been shopping around and there seemingly a range of services available.

Was wondering if anyone here had experience to share with these third party integrations. We're mostly looking to integrate estimates/invoicing/contacts which we access through the Finance module on Zoho and the Zoho Books app. Which services are best/simplest/cheapest for this? 

I note that a number of these services seem to only offer the service between the CRM and Sage. Would these still sync stuff from Zoho Books, as this is synced with our Zoho CRM through the Zoho Finance module?

Any advice welcome.

Cheers!
