Window Cleaning Quoting and Invoicing App for a Solo Operator (2026)
For a solo window cleaning business, ShowTheReceipts ($15/mo) covers the whole job — quote at the curb, invoice once the windows are done, and take the card before you pack up the squeegees, with cash and Venmo tracked in the same ledger for tax season.
How we picked
Entry-plan prices as published in 2026, checked against each vendor's own pricing page or a recent third-party pricing summary. We judged tools on the one-person window cleaner's real workflow — quote at the door, invoice on completion, get paid before driving off — not on multi-crew or franchise features.
| Software | Starting price | Best for |
|---|---|---|
| ShowTheReceipts That's us | $15/mo | Solo operators: quote at the curb, same-day invoice, card payment, cash & Venmo tracked, tax-ready books |
| Kickserv Flex | $19/mo | Budget scheduling + invoicing, no per-pane quoting tools |
| QuoteIQ | $29.99/mo | Per-pane pricing, before/after photo documentation, good/better/best upsell estimates |
| The Customer Factor | $34.95/mo | Window-cleaning-specific data model, flat rate, unlimited customers |
| Jobber | $49/mo (Core) | Multi-crew dispatch and a growing client hub |
The solo window cleaner’s real workflow
Window cleaning gets quoted standing in the driveway: you walk the exterior, count stories and problem panes, and give a number before you even unload the ladder. Your software should support that on-the-spot loop, not add steps between you and getting paid.
1. ShowTheReceipts — $15/mo
Quote from your phone standing at the curb, convert it to an invoice the moment the last window’s dry, charge the card before you fold the ladder back into the truck. Cash and Venmo jobs land in the same ledger as card payments, so tax season is an export instead of a shoebox. Every past job stays on the customer’s record, which matters in a trade where the same houses call you back every spring and fall.
2. Kickserv Flex — $19/mo
The honest budget pick: scheduling, customer history, and invoicing that works. No per-pane or story-based quoting tools, so pricing irregular jobs is still eyeballed and typed in by hand.
3. QuoteIQ — $29.99/mo
The feature standout for this trade: per-window and per-pane pricing, good/better/best upsell estimates that tack on screens and gutter brightening, and before/after photo capture per job.
Skip it if you already price by eyeballing the house rather than counting individual panes — most true solo operators do, and the pane-level math is what you’re paying the extra $15 a month for.
4. The Customer Factor — $34.95/mo
Built specifically for window cleaners and similar exterior-service trades: unlimited customers, unlimited employees, and a flat rate with no add-on tiers. The trade-specific fields (window counts, story height, screen tracking) are baked in rather than bolted on.
5. Jobber — $49/mo (Core)
A broader field-service platform — quoting, scheduling, dispatch, invoicing — that happens to cover window cleaning well. Worth it once you’re running more than one crew; overkill for a single operator who just needs to quote, invoice, and get paid.
Frequently asked questions
What software does a solo window cleaning business actually need?
On-site quoting, same-day invoicing, and on-site card payment — plus a record of what you charged last time so repeat customers are quick to rebook. Crew scheduling boards and route optimization for multiple trucks are features a one-person operator will set up once and never touch again.
What do I get with ShowTheReceipts for $15/month?
The solo-operator workflow at the lowest paid price — quote at the curb, invoice the same day, charge the card before you pack up, cash and Venmo tracked in the same ledger, and tax-ready exports at year end. Upgrade to Pro for automatic payment reminders and recurring-invoice automation once you've got enough seasonal regulars to make chasing them worth automating.
Is QuoteIQ's per-pane pricing tool worth it for a one-person operation?
It's genuinely useful if you're quoting a lot of large homes with irregular window counts and want the math done for you on-site. But most solo operators price by the job after a quick walk-around, not by counting panes in an app — so it's a feature you're paying an extra $15/month for whether you use it weekly or never.
