Fish Window Cleaning franchise unit economics

Fish Window Cleaning franchisees run commercial and residential window cleaning routes from three territory package sizes. Across the 254 outlets reporting for 2025 the system average was $530,840, up 8.4% in two years, while new customers won each year fell 6.4%. The royalty falls from 8% to 5% as volume rises and sits against a minimum standard that climbs every year of the term, so the two move in opposite directions.

Key idea

The system average rose 8.4% to $530,840 while new customers won each year fell 6.4%. Growth came from the book already on the van. Meanwhile the fee structure pulls in two directions at once: the royalty rate drops from 8% to 5% as volume rises. The minimum it is charged on climbs every year of the term.

Units reporting254 outlets, 2025
System average revenue$530,840
Royalty8% falling to 5%
Total investment$111,900–$179,900
  1. Revenue rose 8.4% in two years while new customers fell 6.4%. A system average of $530,840 against $489,894, on 219 new customers against 234 *, so revenue for each new customer won rose 15.8% to $2,424, and the existing route did the work.
  2. The royalty falls from 8% to 5% as sales rise, and the minimum it applies to rises every year. 8% up to $500,000 of annual sales, then 7%, 6% and 5% above $1,200,000, against a standard-package minimum climbing from $68,640 a year to $371,800 by year ten *.
  3. A bottom-tenth of the group, ranked by sales outlet falls short of the year-three minimum standard. $124,499 of average revenue against a standard-package requirement of $148,720 *, and at a year-ten standard that outlet would owe an effective 23.89% of what it actually billed.
  4. The top tenth bills 11.6 times the bottom tenth. $1,444,227 against $124,499 *, and outlet to outlet the range ran $2,814,785 to $61,872, which is 45.5 times.
  5. Every outlet that closed in three years had been trading more than a year. 6, 11 and 7 permanent closures across 2023 to 2025, with zero of them open under twelve months, so these were established routes.
What this filing does not disclose
  • No median. Only an average is published, which a few large locations can lift on their own.
  • No profit figure. The filing reports sales and not earnings, so what an owner keeps is not disclosed.
  • No cost lines. Wages, rent and cost of goods are not broken out, so margin cannot be rebuilt from the document.

Questions worth putting to Fish Window Cleaning

The filing answers what it answers. These are the gaps an owner or a buyer should close directly.

  1. What do locations at the median spend on wages and rent as a share of sales? The filing reports sales only.
  2. What separates the highest-selling locations from the lowest: trade area, years open, size, or the owner?
  3. How long does a new location take to reach the average you publish, and what does the build-up look like month by month?
  4. At what level of sales do the minimum charges stop applying and the percentage take over?
  5. How many Fish Window Cleaning locations closed, were sold, or changed hands last year, and why?

If you want this done for you

What happens next

Everything above came out of a filing. Doing it on your own numbers means the books have to produce the same lines: sales, wages, occupancy, fees and what is left, by location, every month. That is the work.

  1. The call, twenty minutesYou describe the business and where the numbers are letting you down. We tell you honestly whether we can help, and what we would start with. No pitch deck.
  2. We look at the fileYou give us read access to the books as they are. We come back with what is wrong, what it will take to fix, and whether the answer is bookkeeping, controller work, or something else.
  3. A written scope and a priceWhat we do each month, what you get, the date it lands, and the fee. Agreed before anything starts, and it does not move without you agreeing it.
  4. Transition, then the first closeAccess, systems, and the opening balances. The first close lands on the date in the scope, and every one after it does too.

Averan is not a CPA firm and does not file taxes. Your CPA keeps that, and we keep the books they file from.
