Most partnerships do not fail at the handshake. They fail in the eight weeks after it, when nobody owns the next step.
The same onboarding can take two weeks or two months, and the difference is rarely the firm. It is whether there was a plan on paper before the first call.
This is that plan. Fourteen days, start to finish, from signed agreement to a partner handling a real client case on their own.
Why two weeks is the right target
A law firm agrees to work with you when they are excited. That excitement has a shelf life. Every week you spend on setup is a week the partner is not earning anything from the relationship, and a week their team forgets why they signed up.
Two weeks is short enough to keep the energy and long enough to do the work properly. Anything faster usually means you skipped the training and you will pay for it later in support tickets. Anything slower and you are relying on the partner to stay interested while nothing happens.
There is a second reason. A short onboarding forces you to write things down. If you have to move in fourteen days, you cannot invent the process each time.
What a partner actually needs before they can start
Before the day by day plan, it helps to be clear about the finish line. A partner is ready when four things are true.
They can log in and see their own dashboard. They know what a client request looks like when it arrives. They know how they get paid and when. And they have a named person on your side to call when something breaks.
That is it. Everything below exists to get to those four points.
Days 1 and 2: The fit call and the paperwork
Start with a call that is not a sales call. The agreement is signed. This call is about how the firm works day to day.
Ask what kinds of estate matters they handle most. Ask how many people will use the platform. Ask who reviews documents and who signs off. Ask what their busiest days look like. You are trying to learn where your process will rub against theirs.
Two questions matter more than the rest.
Who is the champion? One named person at the firm who wants this to work. Without a champion, onboarding stalls the first time someone is on holiday.
Who is the backup? Champions get busy. If only one person at the firm can operate the platform, you have built a single point of failure into the relationship.
While that call is happening, send the paperwork in parallel. Do not wait for the call to finish. The partner agreement, the data processing terms, the bank details form for payouts, and the list of people who need accounts. Sending these on day one rather than day five is the single easiest way to save a week.
One practical note on the account list. Ask for full name, work email, role, and whether the person needs to approve documents or only view them. Collecting roles up front means you configure permissions once instead of three times.
Days 3 and 4: Verification and accounts
This is the part that quietly eats time, so treat it as its own block of work.
You are verifying that the firm is what it says it is. Registration details, practising licence, the jurisdictions they can operate in, and the identity of the people who will get accounts. On a platform that touches wills and personal records, this is not a formality. Every account you create can eventually see something sensitive.
Do the checks in a fixed order and record the result of each one. When an auditor asks next year how you verified a partner, you want a file, not a memory.
Create the accounts only after verification clears. Send invites with a short note that says what to expect, not a bare system email. People ignore bare system emails.
Set permissions to the smallest level that lets each person do their job. A paralegal who uploads documents does not need approval rights. You can widen access later. Narrowing it after the fact is awkward and it usually does not happen.
Days 5 and 6: The walkthrough
Now the training. One session, sixty minutes, screen shared, recorded.
Record it. This is the highest return thirty seconds of effort in the whole process. The firm will hire someone in three months and that recording becomes their training. It also protects you when somebody says nobody showed them how to do something.
Cover four things in order.
Where work arrives. Show the queue. Show what a new client request looks like the moment it lands. Show the notification the firm gets. People need to know where to look before they need to know anything else.
How to handle one case end to end. Open a test case. Review it, ask the client for a missing document, receive the upload, prepare the draft, send it back. One complete loop beats a feature tour.
What the client sees. Partners handle clients better when they know exactly what the client is looking at on the other side. Show them the client view.
What to do when something is wrong. Wrong document, client not responding, request that should never have come to them. Show the exit route for each.
Skip everything else. Reporting, settings, the bits of the product they will touch once a quarter. Those go in a follow up note. A sixty minute session with four clear things beats a two hour session with twenty.
Days 7 and 8: The dry run
Give the firm a practice case and let them work it without you in the room.
Use realistic content, not lorem ipsum. A fake client with a slightly messy situation. A missing document. A name spelled two different ways. Real cases are messy and you want the partner to hit the messiness while the stakes are zero.
Watch what they do. Where they hesitate is where your product or your training is unclear. Two firms hesitating in the same place is not a coincidence, it is a bug report.
At the end of the dry run, ask one question: what would you not know how to do if a real client landed tomorrow? The answers are usually short, specific, and fixable in an afternoon.
Days 9 and 10: Money and expectations
Do not leave commercials to the end. Partners who are unsure about money quietly slow down.
Confirm four things in writing.
What the firm earns per matter or per plan. When payouts run. Where the money lands. What happens when a case is cancelled halfway through.
Then set the response time expectation in both directions. How fast the firm will respond to a new client request, and how fast you will respond when the firm raises a problem. Write both numbers down. A commitment that only runs one way is not a partnership, it is a service level agreement with extra steps.
Also agree on volume. If you tell a firm to expect twenty matters a month and you send three, you have damaged trust for reasons that have nothing to do with your product. Give an honest range and say it is a range.
Days 11 and 12: The first real case, supervised
Route one live client to the partner and stay close.
Supervised does not mean you do the work. It means somebody on your side is watching the case move and is reachable within minutes. Tell the partner explicitly: for this one case, message me directly and I will answer.
Real cases surface things practice cases never do. A client who uploads a photo of a document instead of a scan. A partner who assumed something about your process that was never true. A step that works fine but takes eleven clicks.
Log every one of these. Do not fix them live unless they block the case. Fix them in the week after, then tell the partner you fixed them. Partners remember that.
Days 13 and 14: Handover and close
Two final steps.
The handover. The partner moves from your direct line to normal support. Introduce the support channel by name, tell them the response time, and tell them who escalates if it is urgent. If this step is skipped, partners keep messaging whoever onboarded them forever, which works right up until that person is on leave.
The close call. Thirty minutes. Three questions. What was confusing? What is still missing? What would make you send us more work?
Write the answers into the playbook itself. A playbook that does not change after every onboarding is not being used.
The five things that actually cause delays
Five blockers account for most of the lost time.
Paperwork sent late. Send everything on day one, in parallel, before you need it.
Verification queued behind something else. Give it a dedicated slot on days 3 and 4 and an owner by name.
Too many people invited. Ten accounts on day one means ten people confused instead of two people trained. Start with the champion and the backup, add the rest in week three.
Training scheduled around one person's calendar. If the champion cannot make the session this week, run it with the backup and send the recording. Do not lose seven days to a calendar.
No first case ready. If there is no live client to route on day eleven, the partner goes cold. Line one up in week one, or use a scheduled internal case so the loop still closes.
What to measure
Four numbers tell you whether partner operations is working.
Days from signature to first live case. The headline number. Fourteen or fewer.
Days from signature to first payout. Partners believe the relationship is real when money arrives, not when the account is created.
Support tickets in the first month. High ticket volume usually means the walkthrough was weak, not that the partner is difficult.
Share of partners active in month three. The one that matters. Onboarding is not successful if the firm goes quiet after four cases.
Track them per partner, not just as an average. Averages hide the firm that has been stuck for a month.
The part people skip
Write the playbook down and use the same one every time.
It is tempting to treat each firm as special. Some are. But roughly ninety percent of onboarding is identical from firm to firm, and the ten percent that is genuinely different is easier to see when the rest is standard.
The playbook is also how the work survives you. If onboarding lives only in the head of one operations person, you can onboard one firm at a time forever. Written down, it can be run by someone in their second week on the job, and you can run three at once.
That is the real goal. Not a faster onboarding. A repeatable one.
Frequently Asked Questions
How long does it usually take to onboard a law firm onto an estate planning platform?
With a written playbook and paperwork sent on day one, two weeks is realistic. Without one, six to eight weeks is common. The delay is almost always verification, paperwork, or scheduling, not the software.
Who from the firm needs to be involved?
At minimum a champion who will use the platform daily and a backup who can cover them. Adding more people before the first live case usually slows things down.
What is the most common reason partner onboarding stalls?
Nobody owns the next step. Every stage should have a named owner and a date, on both sides.
Should the first case be a real client?
Yes, after a practice run. A supervised real case in week two is the only reliable way to find the gaps before they hurt someone.
How do you know onboarding worked?
The partner is still handling cases in month three without needing help. Everything before that is setup.
