How It Works
Day before you launch you need to start doing these steps every day until your token migration is complete.Export your members
Export your active membership list from your previous POS as a CSV or XLSX
file.
Plan Mapping
The first time you upload an Interim Import, FlexWash asks you to map plans from the old POS to packages in FlexWash. This step is important because FlexWash uses these mappings to determine which package each member receives.
Once plans are mapped, FlexWash remembers them for future imports, so you only
need to map each plan once.
How to Test
Before launching FlexWash do a sample import and use the simulator to verify an Interim Import member is recognized. Enter the license plate in the simulator and verify the vehicle is recognized as an Interim Import member, with the membership benefit automatically applied and the ability to redeem the wash.
Troubleshooting
Active Member Issues
If a member who is active in your Ex-POS does not appear as an Interim Import member in FlexWash, check the following.Verify the interim record and recharge date
Search for the member in the Manage tab and confirm:

- The member appears in the results.
- The recharge date is less than 30 days old. If the recharge date is older than one month (or the length of the prepaid package configuration), the member no longer qualifies as active.
Verify the plan mapping
Members that appear in Interim Imports must have a plan. Confirm the
member’s plan is mapped to a valid FlexWash package.If a plan is not mapped:
- The member is not recognized.
- FlexWash does not know which wash package to grant.
Check the uploaded export file
If the member does not appear in the Manage tab:
- Open the export file that was uploaded.
- Search for the vehicle plate number.
- Confirm the plate exists in the file.
- Verify the correct file was uploaded.
Non-Active Member Issues
If a member is not active in your Ex-POS but is treated as active in FlexWash, search for the member in the Manage tab, open their details, and check whether the Ex-POS records indicate the member is active.
