Frequently asked questions: Odoo Enterprise vs. work4all
Does Odoo replace work4all?
For many small and medium-sized DACH businesses, Odoo can replace work4all as a full ERP and additionally brings integrated financial accounting, deep manufacturing and its own web shop. work4all remains strong on the integrated CRM with Outlook and DMS integration as well as on the low-cost entry.
What is the biggest difference in accounting?
Odoo includes a full integrated financial accounting (double-entry) including DATEV, ZUGFeRD and GoBD. work4all offers only accounting preparation and the DATEV interface; the actual bookkeeping runs at the tax adviser.
Can I use Odoo and work4all together?
Technically, the two can be coupled via DATEV or interfaces, but this rarely makes sense because both cover the same CRM and inventory-management area. In practice, one of the two systems is chosen as the leading platform.
Who benefits from work4all rather than Odoo?
work4all is worthwhile for small and medium-sized DACH businesses that want CRM, inventory management and projects cheaply from a single source and whose bookkeeping runs at the tax adviser via DATEV anyway. Those who weight predictable, low entry prices and DACH proximity more highly than manufacturing depth, a web shop and open source are well served by work4all.
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.
