Recurring revenue model for a one-time-service business — what I built

I bought a pressure washing company last year. Classic one-time-service business — customer calls once, you wash their house, they maybe call again in 2 years. Zero recurring revenue. I hated that model. Coming from ecom where subscription revenue is king, I needed to fix this. Built a "Home Maintenance Club": - $29/month or $299/year - Includes: annual house wash, annual driveway wash, gutter cleaning twice a year, 10% off any additional services - Cost to fulfill: about $180/year in labor and supplies - Margin after fulfillment: roughly 40% on annual plan Results after 10 months: - 127 members signed up - Monthly recurring revenue: ~$3,400 - Retention rate: 89% (way better than I expected) - Members also book additional services at a higher rate — they feel like "insiders" The game-changer was the annual plan. $299 upfront means cash in hand and the customer is committed for the year. We schedule all 4 visits at signup so the calendar fills itself. The one-time customers still exist and that's fine. But having a predictable $3,400/month base that grows every month completely changes how I think about the business. I'm not waking up wondering if the phone will ring.
