CloudScan offers simple duplicate check functionality, which can be enabled on CloudScan settings dialog. This duplicate check will show user a warning message, if a similar invoice has been processed earlier.
Duplicate check is using a combination of fields:
Saving duplicate invoice information:
CloudScan saves checksum of field combinations after the user validates the invoice. Information is saved automatically for all customers.
Saving checksum works only if all fields in a combination is present on invoice.
Warning users about duplicate invoices:
CloudScan settings dialog has a setting to "Enable Duplicate Check".
When duplicate check is enabled, CloudScan client makes duplicate check request to CloudScan server, when user validates the invoice.
Client first calculates checksum of current invoice and if the same checksum is found from the server, client will give a warning:
Duplicate check works between sessions and also if same invoice is processed from different workstations.
Duplicate check works for 180 days after the invoice was validated.
