Frequently asked questions: Odoo Enterprise vs. ams-erp
Does Odoo replace ams.erp?
Only to a degree. Odoo covers accounting, CRM, purchasing, inventory, HR and payroll broadly and is considerably stronger in the front office and trade. For complex one-off and project manufacturing with real-time costing and an end-to-end project file, ams.erp is deeper in its field.
Can I use Odoo and ams.erp together?
In principle yes, since both offer open APIs and low-code approaches (ams.flex). In practice, however, one of the systems tends to be chosen as the leading ERP, because running processes in parallel creates effort.
For whom is switching to Odoo worthwhile?
For businesses that, alongside manufacturing, also need trade, a webshop, marketing and a modern front office, that value transparent pricing and open source, and whose manufacturing is more series- or stock-oriented than pure project manufacturing.
What sets Odoo and ams.erp apart in project manufacturing?
ams.erp is specialised in batch size 1+ and offers real-time costing, dynamic bills of materials and a project file across the entire lifecycle. Odoo maps project manufacturing only to a limited extent and is there inferior to the industry specialist.
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.
