Frequently asked questions: Odoo Enterprise vs. ADDISON Stotax
Does Odoo replace ADDISON/Stotax?
No. ADDISON/Stotax, like DATEV, is specialised in tax, accounting, annual accounts, German payroll and practice work. Odoo covers the operational processes, but does not deliver the deep German payroll and the complete tax returns turnkey.
Can I use Odoo and ADDISON/Stotax together?
Yes, that is the usual case. Odoo runs as the operational ERP for order-to-cash and procure-to-pay, while bookkeeping, balance sheet, tax returns and payroll stay with the tax practice in ADDISON/Stotax via DATEV or export.
What sets Odoo and ADDISON/Stotax apart on payroll?
ADDISON/Stotax offers deep, legally compliant German payroll with statutory-health-insurance certification, social-security reporting and eAU, plus automatic legislative updates. Odoo covers German payroll only to a limited extent.
For whom is Odoo worthwhile instead of ADDISON/Stotax?
Odoo is worthwhile as soon as operational processes such as sales, inventory, manufacturing, website or projects are needed beyond accounting and an end-to-end process flow across several departments is called for. As an open, scalable overall platform, however, it does not replace the practice software.
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.
