The Zoho CRM web forms - Dont look great and don't appear to be responsive in design. I thought they'd be better as we pay for Zoho CRM (just signed up today)
The sepearte Zoho app, 'Zoho Forms' - Seem to work well and can look good. Plus easily integrate with Zoho and add Google ad info. However the on going annual cost, seems at first glance a bit much for what might only ever be one simple contact form (*the free version of Zoho forms has the branding which we would not use.).
Contact Form 7 Integration - I've seen a 3rd party plugin on Code Canyon that looks to integrate Contact Form 7 Scripts with Zoho CRM. Though I'm not yet sure how complex the setup will be.
Zoho Forms, may be the best option and we just need to think of it as another cost to get our CRM setup and running.
OR alternatively , as we'd ideally also be able to monitor Bing Ad leads (as well as Google Ads), through the form.. which seems to only be easily achievable with Unbounce.. Perhaps we should just sign up to the much bigger added monthly cost of that instead of choosing Zoho Forms and being limited to only monitoring Google Ad Word ROI.
