Estimate first. Reconcile to the field.

This tool is a planning estimate, not a replacement for an application record. SurfaceOps helps operators pair a cost baseline with field-level chemical records so reports can be reconciled to what was actually applied at each property.

How the usage-cost estimate works

This is a simple planning model: chemical cost per gallon × gallons used per job = chemical cost per job. Multiply job cost by jobs per month for monthly cost, then multiply monthly cost by 12 for annual cost. Monthly gallons are gallons per job × jobs per month.

For example, $4 per gallon × 10 gallons per job = $40 per job. At four jobs per month, that is $160 per month, $1,920 per year, and 40 gallons per month.

Estimate versus actual field records

The calculator helps with planning, pricing, and recurring budget conversations. It does not claim to know what a crew actually applied. Weather, surface, dilution, growth, and application technique can change real usage, so use the estimate as a baseline and reconcile it against completed-job records.

How SurfaceOps supports accurate chemical reporting

SurfaceOps chemical_log_entries records the chemical, applied date, job address, dilution, volume, surface, and technician for each application. Optional GPS, photos, and verification details add evidence when a property manager, HOA, insurer, or regulator needs more than a monthly estimate. That field record is what lets recurring chemical reports be checked against real applications.
