Pool service is heavily seasonal: opening calls cluster in April-May, closing calls cluster in September-October, and weekly service runs through summer. A single late-spring weekend can drive 100+ inquiries — most independent pool companies cannot staff for that.
The trade press (Pool & Spa News) consistently reports that pool companies who answer over 85% of opening-season calls add 20-30% more annual contracts than those who answer under 60%. The reason is straightforward: customers book whoever picks up first and gives a real-feeling quote.
Most independent pool services have one office admin who's also doing the chemical orders. Calls during the spring rush roll to voicemail. By the time you call back, three other companies have already opened the customer's pool.
OnCall picks up every spring-season inquiry. It captures pool size and type (in-ground, above-ground, gunite, vinyl, fiberglass), age, last-service status, current concerns (algae, cloudy water, equipment issues), and books opening, closing, or weekly visits. It quotes from your published rate card if loaded. See pricing — most pilots run $70-110 a month in usage.
