When a member adds a vehicle or upgrades mid-cycle, FlexWash automatically calculates a prorated charge for the remaining days until their next billing date. Members pay only for actual service time.
How Proration Works
The prorated amount uses actual day counts for accuracy:
Prorated Charge = Package Price × (Days Remaining ÷ Days in Billing Cycle)
- Package: $30/month
- Billing date: 20th
- Vehicle added: March 5th (15 days remaining)
- Billing cycle: 28 days (Feb 20 to Mar 20)
When Proration Applies
Adding a Vehicle to an Existing Membership
A member with an active membership adds a second vehicle. They pay a prorated amount for the new vehicle covering the remaining days in the current cycle.
| Event | Charge |
|---|
| Signup March 1st with one vehicle | Full price |
| Add second vehicle March 15th ($25 package) | ~$12.50 (16 days remaining) |
| April 1st renewal | Full price for both vehicles |
Upgrading to a Higher Package
When upgrading mid-cycle, the member pays a prorated amount for the price difference.
| Current Package | New Package | Days Remaining | Prorated Upgrade |
|---|
| $20 Basic | $35 Premium | 10 days | 15×(10/28)=5.36 |
Reactivating After Validity Expires
If a frozen or cancelled membership is reactivated after the paid period expires, a prorated charge covers the days until the next billing date.
When Proration Does NOT Apply
New Customer Signup
New customers start fresh. The billing date is set to today, they pay the full monthly price, and receive a full month of service.
Downgrading to a Lower Package
No charge. The member keeps their current package through the billing date, then the lower rate takes effect.
| Action | Immediate Charge | At Next Billing |
|---|
| Downgrade from 35to20 | $0 | $20 |
Reactivating Within Paid Period
If a member reactivates before their paid validity expires, there’s no charge. They already paid for this period.
House and Fleet Accounts
Special account types have different billing arrangements and typically bypass standard proration.
FAQ
Are taxes prorated too?
Yes. Taxes are calculated on the prorated base amount, so they scale proportionally.
