Billing
Asking for reviews after a invoice without nagging
Reviews are the cheapest marketing in billing and the one most companies handle by hoping.
Timing decides everything. The window is the day of the invoice, while the yard looks obviously better. A week later the moment has gone.
Ask the customers who are pleased, one at a time, with a link that takes one tap. Do not blast a list, and never buy them.
Volume matters less than recency. A steady trickle of recent reviews outranks a pile of old ones, and it is what a homeowner comparing three companies actually reads.
The only reason it does not happen is that nobody owns the task. It takes seconds per customer, and it belongs to whoever runs your office.
