Structure pool service route pricing and chemical cost pass-through so margins stay predictable as chemical prices fluctuate

Steps

1. Separate the flat labor/route-visit fee from variable chemical costs in the pricing model, rather than bundling chemicals into a single flat rate that erodes margin when chemical prices spike
2. Decide on a pass-through method: itemized chemical billing at cost-plus-markup, a chemical allowance included in the flat fee with overage billed separately, or a fully bundled rate that's periodically repriced against current chemical costs
3. Track actual chemical cost per pool over time, not just route-level averages, to catch outlier accounts (e.g., high-CYA or high-demand pools) that are consistently under-priced relative to usage
4. Build in a review cadence (e.g., quarterly or seasonally) to reprice bundled/flat-fee accounts against current wholesale chemical costs, since chemical prices can swing significantly
5. Clearly disclose the pricing structure and any pass-through/surcharge mechanism to customers in the service agreement to avoid billing disputes
