3. **Integration complexity** - Especially with older SAP ERP versions or non-standard implementations
4. **Machine learning model training** - Requires substantial invoice datasets and domain expertise
5. **Multi-language support** - Supporting global invoices with different languages and formats
### Business Challenges
1. **Total cost of ownership** - BTP consumption-based pricing may exceed expectations for high-volume processing
2. **Development timeline** - Complex project requiring multi-disciplinary expertise
3. **Change management** - User adoption and process change management
4. **Feature parity with mature solutions** - ReadSoft has decades of refinement
5. **Compliance requirements** - Meeting varying global compliance standards for e-invoicing
### Operational Challenges
1. **Exception handling efficiency** - Building interfaces for quick resolution of exceptions
2. **Continuous improvement mechanism** - Ensuring the system learns from corrections
3. **Deployment complexity** - Multi-environment, multi-region deployment considerations
4. **Support model** - Establishing L1-L3 support for a custom-built solution
5. **Documentation requirements** - Extensive technical and user documentation needed
### Strategic Challenges
