How the subtotal is calculated

The example line for cabinet and supply check is 1 job × $135.00 = $135.00. This line is one part of the complete 7-item estimate and uses a fictional unit rate.

The document sums the rounded line amounts to $1,400.00 . Tax and markup are not included; a zero tax field in a sample document does not mean a real project is tax-exempt. Confirm the actual treatment for the job you are quoting.

Measurement to verify: Measure cabinet clearances, pipe arrangement, service access and faucet-hole plan. Selection to verify: Separate filter kit, faucet and connector allowances; note future cartridge service is outside the quote.

Assumptions and exclusions

Confirm supply isolation and cabinet space before drilling the counter or fitting the unit.

Outside the stated scope: No whole-house treatment, water quality guarantee or countertop replacement.

A countertop that cannot accept the faucet needs another product or scope. If the scope changes after a client reviews the estimate, update the relevant quantities, allowances and written exclusions before sharing a revised PDF.
