high-level Member imports are often the most stressful part of upgrading a car wash POS. You’ve invested years building your membership base, and recurring revenue is the backbone of your business. At FlexWash, token migration is something we specialize in. We’ve successfully migrated 100+ sites with an above 98% membership transfer rate, while avoiding the common issues operators fear most: double billing, missed charges, and forced card re-entry. We achieve this because FlexWash operates higher up the payment stack than most car wash POS providers, allowing us to coordinate secure, processor-level token transfers instead of relying on brittle workarounds.

​
Key Terms

  • Ex-POS: Your current POS system
  • Ex-Processor: The payment processor used by your Ex-POS (e.g. TSYS, Fiserv)
  • FlexWash: Your new POS
  • Adyen: FlexWash’s payments platform

​
Export

In most cases, the Ex-POS will request a shutoff date for recurring billing. We recommend setting this at least 30 days out. If timelines change, ask for adjustments with a minimum of 7 days’ notice. During this period, we set up interim imports to ensure your site continues operating smoothly and members remain active without disruption.

​
POS Data Export

You notify your Ex-POS that you are migrating to FlexWash and CC our team on an email thread. They provide a data export containing all membership details except credit card numbers.

​
Credit Card Data

You request an introduction to your Ex-Processor to export existing card tokens. Once connected, you CC your FlexWash onboarding specialist. From there, we coordinate a secure, encrypted processor-to-processor transfer directly between your Ex-Processor and Adyen. This minimizes data handling and avoids unnecessary exposure.

​
Import

Once all export files are received, we begin the import process.

​
Phase 1: Controlled Test Import

We start with a small, representative sample of approximately 10 members. These are intentionally chosen to reflect real-world edge cases, such as:
  • Members due to be re-charged tomorrow
  • Members who recently declined
  • Members with multiple vehicles and/or bulk discounts
  • Members on promotional pricing (e.g. $1 intro periods)
These members are imported first, then you manually cancel them in the Ex-POS to prevent double billing. The following morning, we manually verify that all charges processed exactly as expected. This step allows us to validate the migration under real conditions before touching your full membership base.

​
Phase 2: Full Migration

Once recurring billing is fully disabled in the Ex-POS, we migrate the remaining members on the same day. After completion, you receive a detailed migration report showing:
  • How many memberships transferred successfully
  • Which memberships (if any) failed and why
This ensures full transparency and allows targeted follow-up where needed.

​
The Result

The result is a measured, audited migration process with multiple safeguards, designed to protect your revenue and your customer relationships. Token migration doesn’t have to be a leap of faith. With FlexWash, it’s a controlled, proven process, and one you can feel confident putting in front of your customers.
