Testing and validating e-invoices When you have configured the Design Center Project, you must carry out acceptance testing. During the acceptance testing, you have the possibility to prove the authenticity and integrity of the e-invoices produced using the TrustWeaver e-Invoice Audit Page for testing. Note: Validating the produced e-invoices is just one way of testing your solution. In addition, you must carry out standard acceptance testing. To test and validate e-invoices Upload and validate archived e-invoices at the following address: https://tsod.trustweaver.com/test/tseiod/validate.aspx When you submit e-invoices containing digital signatures, you also receive information about the authenticity and integrity of the e-invoices and the associated policy information. Note: You can only use the web page above to validate e-invoices created during the testing phase. For information on how to validate e-invoices created during the production phase, see the E-Invoice Center End-User Guide.
