Odoo and Zoho One are both broad business software offerings, and both cover a wide range of functions. The key difference is how the pieces relate.
What each one is
Zoho One is Zoho's offering that bundles a wide range of Zoho's business applications together. Odoo is a modular business suite, also covering a wide range of functions, built so the modules are parts of one connected system sharing a single model.
The key difference: a suite versus a bundle
Both offer breadth, so the honest comparison turns on how integrated that breadth is. Odoo is built, from the ground up, as one system: its applications share one model, so the connection between them is inherent. Zoho One bundles a wide family of applications, and while Zoho works on having them connect, the design origin is a catalogue of apps brought together rather than a single unified system. The practical question is how much a business values everything being genuinely one system versus a well-stocked bundle of apps that connect.
Where Zoho One is competitive
Zoho One is accessible, affordable, and offers a very wide bundle of applications. For a business that wants that broad bundle and is comfortable with a family-of-apps model, Zoho One is a reasonable and economical choice, and the breadth of its catalogue is real.
Where Odoo is stronger
Odoo's strength is that its breadth comes as one connected whole. For a business that wants to run much of its operation, including operational areas like manufacturing and inventory, on a single integrated system rather than a bundle of connecting apps, Odoo's unified design is a genuine advantage. Odoo also tends to be stronger in those operational and manufacturing areas, and being open-source at its core, it offers more flexibility to customize and extend.
Which suits which business
Zoho One suits a business that wants a broad, affordable bundle of business apps and is comfortable with a family-of-apps model. Odoo suits a business that wants to run much of its operation, especially if that includes operational and manufacturing functions, on one genuinely connected system, and that values the flexibility of an open core.
The honest verdict
Odoo and Zoho One both offer real breadth, so choose on what you want that breadth to be: one connected system, or a broad bundle of apps. For a business seeking genuine end-to-end integration across many functions, Odoo's unified design is the stronger fit; for a business wanting an affordable broad bundle, Zoho One is competitive.
