Follow up while the job is still fresh
For most service businesses, a first follow-up within one to two business days is reasonable. The goal is not to pressure the customer. It is to make sure they received the estimate and ask whether they have questions.
Keep the message short
A good follow-up can be as simple as: Hi, just checking that you received the estimate for the project. Happy to answer any questions or adjust timing if needed.
Set the next step
If the customer is still deciding, set another follow-up date. Do not leave the quote floating in your inbox or memory.
