The suite question comes before the tool question
Firms usually reach a fork somewhere between 20 and 40 clients. One road is to consolidate everything into a single platform and accept the setup work in return for one login and one place to look. The other is to keep a small stack of narrow tools that each do one job well and can be swapped out on a bad month without touching anything else.
Neither road is wrong, and the wrong move is choosing without naming which one you are on. If you decide you want the platform road, evaluate TaxDome against the other suites your peers use, not against a chaser. If you are on the small stack road, then the question is only whether the document chase is painful enough to be its own line item, and for most bookkeepers with a monthly book it is.
What you keep when you already run a suite
Plenty of firms already own a practice platform and still chase documents by hand, because a portal is a place to put files rather than a system that asks for them again on Thursday. If that describes your week, the useful question is not which product wins. It is whether the follow up work inside your existing system is scheduled and visible, or whether it depends on somebody remembering.
Run the honest test for one month. Count the follow up messages you personally wrote and the items still open at your cutoff date. If both numbers are small, keep what you have. If you wrote 60 messages in a month to get statements out of nine clients, a second small tool that only does chasing pays for itself long before you finish the close.
Cost of the second tool
Firms resist a second subscription for good reasons, and price is rarely the real one. The real cost is another login, another notification stream, and another place a client can be confused about. Weigh that honestly against the alternative, which for most solo bookkeepers is a spreadsheet, a reminder in a calendar, and a sinking memory of who was asked twice.
Our tiers are published: $29, $79 and $169 per month depending on how many client files and users you carry. Set that against the billable hours you currently write off on chasing. The capacity math for a solo bookkeeper makes the comparison easy, because the chase hours come straight out of the same week as the work you get paid for.
