Dormant leads, past inquiries that never converted and past clients who have gone quiet, are leads a practice already paid to acquire once. Re engaging them during the off season, when the team actually has bandwidth to follow up, typically converts at a lower acquisition cost than sourcing a brand new lead through any channel.
Why most practices never do this
During January through April, there is no time to follow up on anything beyond the immediate rush. By the time the season ends, the instinct is to rest, not to revisit old inquiries, and the leads that were never followed up on during the rush simply stay cold indefinitely. This is not a strategy decision, it's a bandwidth problem, and it means most practices are sitting on a real, already paid for list of potential revenue that nobody has time to touch.
What actually counts as a dormant lead
Two groups matter here. First, past inquiries that never converted, someone who called or messaged during a previous season, was interested, and never became a booked engagement, often because the follow up simply didn't happen fast enough during a busy stretch. Second, past clients who have gone quiet, no longer engaging the practice for tax prep, bookkeeping, or advisory work, without having formally left.
Why the off season is the right window
This isn't about urgency, it's about capacity. The off season is when staff actually have time to have a real conversation instead of a rushed one, which makes outreach during this window higher quality, not just higher volume. It's also a natural moment to offer something a tax season conversation doesn't fit well, an advisory relationship, a bookkeeping retainer, a broader engagement than a single return.
How to run it
Pull the list, past inquiries and lapsed clients from the last one to two years. Segment by why they went quiet if that's known, price sensitivity, timing, service fit, since the message differs. Reach out with a genuine, low pressure check in rather than a hard pitch, people who went quiet respond better to "checking in" than to "special offer." Track what converts so the next off season's list building learns from this one.
An automated Off Season Reactivation Campaign runs this exact process without pulling staff off other work during the one window they actually have to catch up. Use the calculator to estimate how much your current dormant list is worth.
