Sorted by role: IT & data protection, accounting, process management, management & procurement.
IT & data protection
Can OXS.eco process XRechnung and ZUGFeRD?
OXS.eco processes structured e-invoices such as XRechnung and ZUGFeRD. The XML data is checked technically and handed into workflows, depending on your configuration and data quality.
Can OXS.eco be connected to Diamant or to our existing ERP systems?
Diamant is already connected. Further ERP connections are possible on request on a project basis and depend on version, interfaces, data model and project setup.
What happens to customer data in the AI features?
How data is actually processed depends on the operating model, the data processing agreement (DPA), the technical and organizational measures (TOMs), sub-processors and your project setup. A DPA is available and the measures are documented. The details should be reviewed with your IT and data protection people. More at AI & data protection.
Accounting
What happens with faulty e-invoices?
Faulty XML structures can be made visible so that accounting or IT can trace the cause and clear it up more easily.
Can OXS.eco do the account assignment for invoices?
OXS.eco prepares account assignment proposals based on historical postings, suppliers, entities, departments or cost centers. The final review stays with the responsible team. Data quality and setup affect how good the proposals are.
How are approvals mapped?
Depending on the configuration, approvals can be mapped in workflows by amount, department, cost center, role or responsibility.
Process management
What are Learning Rules?
Learning Rules can store recurring user decisions so that similar documents are prepared or classified more consistently later on, under the user's control.
Who decides whether automation goes live?
Automation should be introduced in a controlled way. Test runs, a narrow starting scope and sign-off by your team help you check proposals before they go live.
How does a sensible pilot operation start?
A pilot operation usually starts with clearly defined document types, test documents, responsibilities, approval rules and criteria for when proposals go live.
Management & procurement
Is OXS.eco suitable for sectors such as logistics, insurance, financial services or public administration?
OXS.eco covers document-heavy processes in these sectors: accounts payable, mailroom, case files, approvals, evidence and archiving. Whether it fits your case is clarified in the project discussion.
What does OXS.eco cost?
There are no flat-rate packages. For a first orientation, see the starting prices on the pricing page. The actual quote depends on modules, number of users, integrations, document volume and project setup, and follows once your requirements have been clarified.
