Wirehouse to RIA in 90 Days: A Realistic Timeline With Compliance Milestones, Technology Checkpoints, and AUM Retention Benchmarks
A wirehouse-to-RIA transition of a sizable book can realistically run in about 90 days when the compliance, technology, and repapering work is sequenced in parallel rather than in series. The first week is resignation and registration, weeks two through four are repapering and ACATS initiation, and the remaining stretch is exception resolution and retention. Speed comes from preparation done before day one, not from rushing after it.
If you are a senior advisor planning to go independent, the timeline question is the one that keeps you up at night: how long is my book exposed, and what compresses the window. Ninety days is achievable, but only if you treat it as three coordinated phases with defined milestones. The mistake that stretches transitions to six months is running each step after the last one finishes instead of staging them to overlap.
Phase one, days 1 to 7: resign, register, protect the data
The opening week sets the ceiling on everything downstream. The critical-path items are your resignation, your registration filings, and your Broker Protocol handling. Your new firm files your Form U4 while your departing firm files your Form U5, and the gap between them defines how long you sit between registrations. Broker Protocol status governs exactly what client data you may take, so both firms' membership has to be verified before you resign, not after. Our guide on verifying Broker Protocol membership before you resign covers that check in detail.
The technology checkpoint for week one is having your repapering forms pre-staged. The single biggest accelerant is walking into resignation day with account paperwork already prepared from clean data, so the moment registration clears you can move. A purpose-built advisor transition platform is what makes that pre-staging possible at book scale instead of one account at a time.
Phase two, days 8 to 30: repaper and initiate ACATS
With registration underway and Protocol-permitted data in hand, weeks two through four are the repapering engine. This is where new-firm account forms are completed, client signatures are gathered, and ACATS transfers are initiated. ACATS runs on the National Securities Clearing Corporation's system under FINRA's customer account transfer rules, and every instruction is validated by the carrying firm before assets move. A mismatch on a tax ID, account title, or account type comes back as a NIGO reject and costs a cycle.
The technology checkpoint here is pre-submission validation. Reducing rejects is the difference between a 30-day repaper and a 60-day one. Document intelligence extracts account values directly from statements so the transfer instruction matches the carrying firm's record on the first pass, and the reject categories to catch before submission are broken down in our reference on ACATS reject codes and how pre-validation stops them. Compliance runs in parallel: Reg BI obligations attach to the account recommendations you make in the new structure, and books-and-records requirements mean your transition documentation has to be retained properly from the start.
Phase three, days 31 to 90: resolve exceptions and hold the book
The final phase is not idle time. It is where the accounts that did not transfer cleanly get worked, restricted or nontransferable assets get their residual or liquidation path, and client communication does the heavy lifting on retention. Most attrition in a transition is operational, not emotional. Clients leave because their transfer stalled, a statement looked wrong, or the process felt chaotic, not because they stopped trusting the advisor. The mechanics of holding assets through the move are in our piece on AUM retention during an advisor transition.
Here is the milestone map for the full window.
| Phase | Days | Compliance milestone | Technology checkpoint | Metric to track |
|---|---|---|---|---|
| One | 1 to 7 | Resignation, U4/U5 filed, Protocol status confirmed | Repapering forms pre-staged from clean data | Days to registration clearing |
| Two | 8 to 30 | ACATS initiated, Reg BI and books-and-records in place | Pre-submission validation live, NIGO rate monitored | First-pass ACATS acceptance rate |
| Three | 31 to 90 | Exceptions resolved, restricted assets pathed | Exception queue worked to zero | Percent of AUM repapered and retained |
What "benchmarks" actually means here
Be careful with retention numbers you see quoted elsewhere. Rather than trusting an industry average, set your own baseline and measure against it: the percent of target AUM that has repapered by day 30, day 60, and day 90, and your first-pass ACATS acceptance rate. Those are the numbers that predict your outcome, and they are specific to your book and your custodian. Track them weekly during the transition so a stalling metric surfaces while there is still time to act. Firms and transition consultants running multiple books at once treat these as a live dashboard rather than a post-mortem.
A 90-day transition is not a promise you make to clients; it is a plan you execute by staging the work to overlap and preparing the data before you resign. A worked example of that compression is in this advisor transition case study.
FAQ
Is 90 days realistic for a large book? Yes, when the compliance, repapering, and ACATS work run in parallel and the forms are pre-staged from clean data before resignation. Transitions stretch past 90 days mainly when steps run sequentially or when NIGO rejects force repeated rework, both of which preparation and pre-submission validation address.
What is the biggest time sink in a transition? ACATS rejects and repapering rework. Every reject costs a cycle and a client-visible delay, so the first-pass acceptance rate is the metric that most directly drives your timeline. Catching data mismatches before submission is where the window compresses.
What compliance work has to happen in the first week? Your resignation, your U4 and U5 filings, and confirming Broker Protocol membership for both firms so you know exactly what client data you may take. Getting Protocol status wrong or filing errors early adds delay that cascades through the rest of the transition.
How should I measure whether the transition is on track? Track percent of target AUM repapered at day 30, 60, and 90 and your first-pass ACATS acceptance rate, measured weekly. Set your own baseline rather than relying on a quoted industry benchmark, because retention depends on your specific book, custodian, and client base.
