Billing & Grace Period

Pricing model

Every period is priced the same way: full monthly base price, any discount applied, then VAT — flat, regardless of how many washes actually get scheduled inside the 30-day window. There’s no proration.

Price (top row) and washes granted (bottom row) are calculated independently — see Known Gaps for the one open question this creates.

Grace period — why it’s measured in days, not washes

A grace period is a payment-collection clock, not a usage clock — it answers “how long do we let someone use the service before they’ve paid,” which is inherently about elapsed time. A wash-count-based grace period would actually reward slow usage: a customer who skips washes would never trip it. Every comparable business model (rent, gym dues, subscription dunning) ties this to calendar time for the same reason.

A customized grace period (an admin extending it for a specific customer) carries forward automatically on every future auto-renewal — it isn’t a one-time override.
