An agency that earns more on big builds has a reason to skip the math. We would rather sell you the right size and keep you as a client.
Here is the math we run with every owner. Say your average job is $400 and you keep 40% of it as profit. That is $160 a job. Our $1,400 plan pays for itself after 9 extra jobs, since 1,400 divided by 160 is 8.75, and nobody sells three quarters of a job.
Now change the ticket. A $60 job at the same 40% margin earns you $24. The same site now needs 59 extra jobs. That can still happen, but it is a much bigger ask.
So we size the site to your numbers. A big ticket can carry a bigger build. A small ticket usually calls for a simple site. That means a few pages, real photos of your work and a booking form that works on a phone. If even that is more than you need, we will say so.
