Client won't send onboarding info? A day-by-day chase
Most stalled AI client intakes are busy owners facing a form that looks like homework. Here is what to collect first, and the reminder sequence to run from day two to day eight.

When a client signs and then goes quiet on the intake form, you lose the deal slowly instead of all at once. Send one reminder at day two, a different ask at day five, and a phone call at day eight. Cut the form down to the few items that block the build, and take the rest by phone. Most stalled intakes are not unwilling clients. They are busy owners facing a form that looks like homework.
This post is the playbook we would run if we were chasing a client for a logo and a set of business hours. It assumes you have already signed the deal and the clock is ticking on your side.
Why do clients stall after they sign?
The money is the easy part for the owner. They decided, they paid or agreed to pay, and the decision is done. What remains is a pile of small chores that belong to nobody on their staff: find the logo file, write down the holiday hours, decide who gets the leads, log into the calendar.
Moxo's 2025 customer onboarding study of more than 300 organizations, as reported by MediaPost, found that 56% of companies see delays processing new clients. Of the factors that erode confidence, 64% pointed to waiting on client information, which topped the list ahead of technical issues at 60%. That study covers B2B onboarding in general, not AI agencies, so treat it as a direction and not a benchmark for your shop. Still, it matches what you will see. The delay is rarely your tooling. It is the client's inbox.
For a local service owner it is worse. The HVAC owner is in a van. The dentist is with a patient. The person who "handles the website" is a nephew. Your form competes with a hundred things that are actually on fire.
What should you collect first, and what can wait?
Treat intake as two piles. The first pile blocks the build. The second makes it better but can arrive after launch.
Blockers are the things the build cannot run without: the business name, the phone number the system answers or texts from, the hours, the list of services, and who receives the leads. Nice-to-haves are photos, longer brand guidelines, secondary pricing bands, and the edge-case answers to odd questions.
On the Lumina Sales side, the onboarding step is built around this idea. It collects once, under your brand, and ties the answers to the fulfillment job. The default dental form, for example, asks for opening hours and holiday cover, services with a price band for each, logo and brand colors, and the calendar, phone number and lead routing. You can change whatever the form asks by default, which matters here. If your client is a one-chair practice that does not have brand guidelines, delete the field instead of watching them stare at it.
Our lists the full set. The short version for stall-fixing is simple. Cut the form until every remaining question is something you would refuse to start without.
Here is the cadence I would use. It is boring on purpose.
Day zero, before they can stall
Send the intake link in the same message as the signed agreement, with one sentence about time: "This takes about ten minutes, and the build starts the moment it is in." Do not promise a number you cannot back up. If the form really takes thirty minutes, say thirty.
Say what they get back. "Once this is in, you will see your system on a test call by the end of the week" is better than "please complete the form," because it ties the chore to the thing they bought. Only say it if your delivery plan supports it. Our post on what happens after the close covers how to set that expectation honestly.
Day two, the easy reminder
Short text, no guilt. "Quick nudge on the intake form. Only the first section blocks us, and it takes about five minutes. Want me to walk through it with you on a call?" The offer of a call is the real message. Some owners would rather talk for ten minutes than type for five.
Day five, change the ask
If day two got nothing, repeating it is useless. Change what you are asking. Shrink it to a single item. "Can you just send me the logo and the business hours? I will fill in the rest from your website."
This works because a half-finished form is heavy and a one-line reply is light. There is also some old psychology behind it. Bluma Zeigarnik's 1920s work found that people remember unfinished tasks better than finished ones, and Laws of UX turns that into plain advice for product teams. Give people a clear sign of progress to motivate them to finish. If your form shows "section 1 of 3, section 1 done," a person who completed that much has a reason to come back. I would not oversell this as a trick. It is a mild nudge, and a confusing form beats it every time.
Day eight, phone
Call. Not a text, not an email. Ask for fifteen minutes and fill the form in yourself while they talk. You are not being pushy. You are doing the part of the job they find boring.
The call also tells you something no text can, which is whether the real problem is the form or the deal.
When the real problem is the deal
Sometimes the silence is buyer's remorse. The client signed on a hot demo call, got home, and started doubting. A reminder cadence will not fix that and can make it worse.
Signs it is the deal and not the form: they ignore the call, they answer with questions about price, or they start asking whether they can "pause for a bit." For those, stop sending form reminders and send a human message instead. "Is anything giving you second thoughts? I would rather hear it now." Then deal with it as a retention problem. Our piece on why AI clients cancel is the better reading for that moment.
Where this playbook does not work
Three honest limits.
First, it does not work if you wait. A client who goes silent for three weeks has mentally moved on, and no cadence recovers that cleanly. Start on day two or do not bother.
Second, it will not rescue a client who never wanted the thing. If a spouse or business partner vetoed the purchase after the signature, a better form changes nothing.
Third, collecting less up front has a cost. A thin intake means the first version of the system gets more things wrong, and you will field more small corrections after launch. That is the right trade for most clients, but price it in. If you charge for revisions, make sure the client knows the first version is built on what they gave you. We cover how to handle those requests in change requests after signing.
What if you are the bottleneck?
Check this before blaming the client. Did you send the link the same day? Is the form on your agency's branded page, or a generic file they have to download? Does it ask for things you already have, like their website URL?
Agencies lose a surprising number of days on their own side. Pull everything you can from the client's public website and prefill it. Showing up with "here is what I found, please correct it" gets answered far faster than a blank field.
FAQ
How long should I wait before calling a client who has not sent intake?
Eight days is a reasonable ceiling, with a text at day two and a smaller ask at day five. If the build has a delivery date you promised, shorten the schedule, because the client's delay becomes your late delivery.
Can I start building before the intake is complete?
You can start on whatever is not blocked, like the structure of the system and the call flow for their trade. Do not go live on guesses. Hours, phone numbers and lead routing are the three things that embarrass you if they are wrong.
Should I charge for delays caused by the client?
Put it in the agreement before signing. A short clause saying the delivery date moves day for day with late client inputs is common and fair. Enforcing it with a fee is a relationship decision, and I would only do it after a polite written warning.
What if the client keeps sending partial information?
Send back a short list of exactly what is still missing, in one message, with the reason each item matters. Vague requests like "need a bit more" get vague answers. A list of two items gets two items.
Next step
Open your current intake form and highlight every field you would not refuse to start without. Delete the rest or move it to a "later" section. If you do not have a branded intake path yet, start a workspace and look at the pricing section to see how a build is priced before you promise a client a date.
