Sidecar by WashLevel

WashLevel Sidecar is a Safari extension that bolts onto the platforms car wash operators already run — Dencar, CryptoPay, or both — and turns raw data into the numbers you actually make decisions with. You check your sites every morning. Sidecar checks everything else. REVENUE & RETAIL Revenue across every site on one screen — today, yesterday, week-to-date, month-to-date, year-over-year, with live month-end projections. Retail dollars per wash with membership billing stripped out, so you see what single-wash customers actually paid. Wash tier mix breakdown, per-device revenue breakdowns, capture rates, and day-of-week baselines that catch the days quietly underperforming. MEMBERS & CHURN Churn risk scoring from each member's own usage history — gone dormant, washing less, new signups who never came back. Cohort retention curves, net member gain/loss by month, and real washes per member adjusted for tenure. Incomplete signup tracking with days-to-renewal countdowns. CUSTOMERS & LICENSE PLATES License plate tracking across locations — return visit frequency and cross-site overlap. Repeat customer analysis for your single-wash regulars. New membership conversion tracking and credit card-based repeat visit identification. VIA GUARD A trigger-or-close recommendation on every Dencar VIA exception — based on actual wash usage, plate match confidence, and past behavior. One-click trigger or close without leaving the page, with override reasons, auto-dismiss rules, and full decision history. WEATHER & FORECASTING Weather-adjusted revenue projections that separate what weather did from what your operation did. 10-day forecast overlay, seasonal modeling built from your own data, and post-rain/post-snow bounce tracking. WASH CODES Bulk wash code generation with tier selection and expiration dates. Full redemption tracking with time-to-redemption charts and tier breakdowns. Printable code cards.
