How much should a plumbing company spend on marketing?
There is no single right number. What a booked job is worth sets it: if a job brings in more than it costs you to win, you can spend more.

Work it out
- Find your average job value and your margin.
- Count how many calls turn into booked jobs.
- Add up what you spend now: ads, lead services, signs, software.
- Divide spend by booked jobs to get your cost per booked job.
- Increase spend on the source with the lowest cost per booked job, and cut the worst one.
FAQ
Is a percentage of revenue a good rule?
It is a starting point some owners use. Your own cost per booked job is a better guide.
Which costs are free?
A Google Business Profile and asking for reviews cost only your time.
When should I raise spend?
When you have capacity to take more jobs and your numbers show a source that pays back.
