If you’ve been working with Zoho Creator for a while and you know a lot about Deluge script, it’s time for you to demonstrate this knowledge by going through the Zoho Creator Developer Program. 
Being certified as a Zoho Creator developer has some nice perks.
You get to be part of a special community where clients who need Zoho Creator reach out to developers on the list. If you want to be a full-time Zoho Creator dev, this is a great way to get recognized. Zoho pays a lot more attention to certified devs: if you have a suggestion for a new feature, they’re more likely to work on it.
If you’re more interested in Zoho CRM, you can become a certified Zoho CRM consultant. This certification is less about testing your knowledge and more about demonstrating that you can work with clients. You need to have three authorized clients who are paying for Zoho CRM and for your consulting services. Once you’ve got three happy clients, you’ll be able to fill out the CRM consultant form and Zoho will then list you on their website.
If you are wondering how you can get paid clients, the way that I started was going on to Upwork.com, which is a freelancing marketplace. There you can find a lot of people looking for Zoho CRM help. If I go into my freelancer account and search for some Zoho jobs, there are tons of clients looking. One person wants Zoho Books integrated in CRM integration, someone wants a Zoho Campaigns manager, another person wants Zoho Books help again, and someone else wants API integration. If you are relatively inexperienced, you might need to bid low initially to get projects but once you have gained experience, it could become a lucrative career for you. If you want to become a certified consultant, this is a great way to start.
I wish you all the best with your future, whether you decide to take Zoho development on as a paid gig or whether you’re simply going to use it for your organization.
