Define the measure before quoting it.
“Members” can mean active paying accounts, enrolled vehicles, historical signups or another measure in a point-of-sale system. State which definition you use and the date of the report. Keep cancelled, paused and payment-failed accounts distinguishable when the system supports that distinction.
A single count gives a snapshot. A series of consistent monthly reports can explain changes over time. Preserve the original system output so a reviewer can understand how the summary was prepared.

Separate revenue from visits.
Recurring membership revenue and the number of member visits answer different questions. Keep retail wash sales, membership billing and other income separate where your records make that possible. Do not treat a wash count as revenue or assume an enrolled account is currently paying.
The International Carwash Association’s reporting discusses membership and retail revenue as separate operating measures. It also highlights the role of cancellations and connected systems in understanding a wash’s performance. These are useful reasons to keep definitions consistent, not a valuation formula for an individual site.
Explain changes and obligations.
Describe material pricing changes, promotions, seasonal patterns and interruptions in service. Note the systems involved in membership billing and whether important arrangements would need further review in a proposed transaction. Avoid assuming a customer relationship, contract or software arrangement can be transferred without checking the actual terms.
For an initial inquiry, broad operating context is enough. Customer-level data and payment information should remain outside an ordinary website form.
Use the first conversation to identify the next questions.
Share the wash format, market, reporting period and a broad description of the program. A reviewer can then identify which records may be relevant to a more detailed discussion. No standard member count establishes a guaranteed price, offer or sale outcome.
