Silence does not always mean no. It usually means the customer is busy, unsure, comparing, or waiting for the right moment.
This is normal. The right move is not a hard sell. It is a clear follow up that answers questions and makes it easy for them to compare confidently.
Offer to clarify the scope, timing, or options. Keep the follow up useful.
Plenty of jobs sit behind other household or business priorities. The customer may still be interested, but the timing is not there yet.
Use a softer follow up, then move the quote into a future review date instead of pushing it every few days.
Some customers go quiet because they are not confident enough to reply with partial questions.
Prompt with one or two likely concerns, like timing, specification, or options, and invite a quick reply.
Sometimes the problem is internal. The quote went out, nobody owned the next step, and by the time someone remembered, the window was gone.
