Survey firms do not sell, they get allocated
A survey practice has no conventional sales funnel. Work arrives as allocations from insurer offices, third-party administrators and corporate clients who have already decided to use you. The commercial question is not how to generate enquiries. It is whether the next allocation comes to you or to the firm down the road.
That decision is made on reliability: whether the surveyor made contact quickly, whether the site visit happened without chasing, whether the report arrived within the expected turnaround and whether queries were answered. All four are measurable, and almost no small firm measures them.
