Frequently asked questions: Odoo Enterprise vs. RZL
Does Odoo replace RZL?
For AT accounting, payroll and tax-firm workflows, RZL is superior out of the box and is not directly replaced by Odoo. In return, Odoo covers the operational full ERP that RZL does not offer, which is why the two are usually complementary rather than competing.
Can I use Odoo and RZL together?
Yes, that is the typical case in practice. RZL, or the tax adviser using RZL, handles accounting, payroll and year-end closing, while Odoo covers the operational processes such as sales, purchasing, inventory, manufacturing, CRM and projects, connected via interfaces and FinanzOnline channels.
What sets Odoo and RZL apart in AT payroll?
RZL brings AT payroll with ÖGK filings and EBICS natively and keeps it up to date with legislation on an ongoing basis. Odoo covers these specifics via the AT localisation or partners and is rated partial there.
Who benefits from Odoo alongside RZL?
Odoo pays off as soon as, beyond accounting and payroll, orders and invoicing, CRM, inventory or manufacturing are needed in one platform. For end-to-end operational processes, an open API and cloud-native operation, Odoo is the fitting complement to the RZL tax-firm core.
Comparing more than two systems?
This comparison puts Odoo against one competitor. If several systems are still open, a structured selection is the better route: requirements first, weighted into must, should and could, then a comparison that justifies every rating. We disclose there where we earn from a system ourselves.
