Deposits lag claims by weeks. That delay makes a billing transition feel safe right up until it suddenly is not — and it is entirely manageable once you sequence around it.
Cash flow breaks during a billing transition for two reasons: claims stop going out during cutover, or nobody works the existing A/R. Running both companies in parallel for 30 days and agreeing A/R ownership in writing prevents both. Deposits lag claims by 30 to 60 days, so problems surface well after everyone has stopped watching.
Submit a claim today and the money arrives in two to six weeks depending on payer. So a transition that goes wrong in week one still looks fine in week three, because deposits are still landing from claims submitted before the change.
The dip appears in week six or eight, by which point the cause is a month old and the claims involved have aged. This delay is the whole reason billing transitions have a bad reputation: not because they are difficult, but because the feedback arrives too late to correct.
Usually not deliberately. Credentials are not ready, a clearinghouse enrolment has not transferred, or nobody is sure whose job it is this week. A fortnight of unsubmitted claims is a fortnight of missing deposits two months later.
The outgoing company stops caring the day notice is given. The incoming company is focused on new claims. Everything already in flight sits still, ages, and some of it crosses a filing deadline.
Secure your own logins to the practice management system, clearinghouse and payer portals. Export a full A/R aging report and open-claims list as your baseline. Confirm data ownership and notice terms in the existing contract.
Before notice, agree with the incoming company who works the open A/R and at what rate. Then give notice with the overlap period stated explicitly.
New claims go to the new company. Existing claims continue to be worked where they are, to the agreed date. Both sides report weekly, and you compare against the baseline you exported.
This is when the first fully-transitioned claims pay. Compare against the same period last year rather than last month. If something broke in week four, this is where it shows — and because you have a baseline, you can prove where.
Your A/R aging report from the day before notice. Everything else is recoverable; a missing baseline is not. Without it you cannot tell six months later whether old claims were worked or quietly written off, and nobody will be able to tell you.
The transition checklist covers every access and handover item individually.
New clients start with a 30-day pilot alongside their existing setup, so nothing is switched off until claims are flowing normally. Send an aging report and we will map the sequence for your situation.
