Odoo suits businesses that want one integrated system for accounting, inventory, sales and operations, with a free open source Community edition and the option to host it yourself. Zoho One suits businesses that want a large suite of ready-made apps for sales, marketing, support, finance and HR under one login. If you hold stock or manufacture, look at Odoo first; if you sell services and want CRM-led apps, look at Zoho One.
Both promise to replace a pile of separate tools with one connected system. They come at it differently: Odoo starts from open source ERP, while Zoho One bundles Zoho's own cloud apps. I read Odoo's home, editions and plans pages and Zoho One's FAQ and plans pages, plus Zoho's about page.

The Zoho One licence rule to know first
Zoho One's plans page carries a condition that changes the maths for many businesses. Its all-employee model requires you to commit to Zoho One licences for all employees on payroll, not just the people who use the apps. The alternative is its Standard plan with flexible users, where you choose who gets a licence. Work out which model fits before you start the trial, especially if many staff would never log in.
What Odoo's two editions mean
Odoo comes in two editions. Community is open source and free; Enterprise adds extra apps, infrastructure and professional services. Odoo says Community is the core Enterprise is built on and you can switch versions at any time. Its paid plans include hosting on Odoo Online with daily backups on two continents and 24/7 monitoring, plus email support Monday to Friday in English, French, Spanish or Dutch. Custom development hosted on Odoo.sh sits outside those plans.
Where Zoho One stands out
Zoho One's FAQ says it includes more than 50 applications to grow sales, market your business, do your accounting and talk to teammates and customers. It also includes Zoho Creator for building your own apps. Zoho says it has more than 150 million users and 19,000 employees worldwide, which shows how widely its apps are used.

- You hold stock, manufacture or run a warehouse: Odoo's ERP roots fit.

Trying each before you commit
Both let you test fully before you decide. Odoo's Community edition is a free download, and Odoo offers a free trial of its hosted apps. Zoho One's free trial gives you access to its full range for the length of the trial, after which you choose a plan. One limit to note: Zoho's FAQ lists 200 MB of storage on the trial and 20 GB on paid accounts, so load a sample of your data rather than everything.
My advice on Odoo or Zoho
Map the three processes that cause you the most pain, such as stock, invoicing or sales follow-up, and test them end to end in both. If stock and operations come first, Odoo usually feels more natural. If sales, marketing and support come first, Zoho One's apps cover more ground. And check Zoho One's licence rule against your headcount before you commit.
