Octoa is a CRM developed by photographers for photographers. Based in Amsterdam, Octoa is completely GDPR compliant.
As there’s a plugin for Flothemes websites, I can easily connect my contact form on the website with Octoa’s database and keep my website’s design consistent. (Of course you can also embed a form from Octoa on your site.
Octoa manages my contacts, integrates with Gmail, handles my contracts, surveys, my calendar and could also do the invoicing.
