Should exterior and interior be separate line items?

Yes. They're priced differently and take different amounts of time, so a single combined number makes it harder to explain the total if a customer only wants exterior next time.

When should I send the invoice?

On completion, while you're still at the property. Window cleaning has no follow-up visit or material lead time, so there's no reason to invoice later and add a collection step you don't need.

Do screens need their own line?

Yes, whenever you removed and rehung them — it's a distinct step from washing the glass and customers notice when it's missing from a re-quote comparison.

Pricing models: Per-pane counting vs. square footage & pure water systems

Window cleaning pricing relies on pane count, accessibility, and technology:

Per-Pane Counting ($4–$8 Exterior / $8–$15 In & Out per pane): Count individual glass panes (double-hung windows count as 2 panes, sliding glass doors count as 2 large panes). Per-pane pricing provides exact material and time accuracy.
Water-Fed Pole (WFP) Pure Water Systems: Using deionizing (DI) resin and reverse osmosis (RO) tanks to deliver 0-PPM pure water through carbon fiber poles up to 4 stories high. Pure water drying spot-free without ladders increases safety and speeds up exterior production by 2x.
Minimum Job Call-Out Fee ($120–$150): Always enforce a mandatory minimum service charge to cover travel time, equipment setup, and water tank transport.

Itemizing screen cleaning, track detailing, and hard water removal

Never include labor-intensive screen washing or track restoration in standard glass pricing:

Screen Removal & Washing ($3–$6 per screen): Removing screens, scrubbing mesh with specialized screen washers, wiping frames, and re-installing without damaging corner tabs.
Track & Sill Deep Cleaning ($2–$4 per window): Vacuuming dead insects, dirt, and mold from window tracks, followed by microfiber wiping.
Hard Water Mineral Stain Removal ($8–$20 per pane): Sprinkler overspray leaves calcium deposits requiring acid-based chemical restoration, cerium oxide polishing, or specialized steel wool buffing.

On-site billing workflow: Paid before coiling hoses

Take payment immediately upon completing post-wash inspections:

Sunlight Quality Check: Inspect glass panes under direct sunlight to ensure zero streaks or water drops remain on sills.
Driveway Payment Collection: Present the digital invoice on your mobile tablet. Collect credit card, debit card, Apple Pay, cash, or Venmo payments directly in the driveway.
