Every service business has the same first week: a signed agreement, then four days of emails collecting the things you need to actually start. Logins, brand assets, the name of the person who approves things, the deadline that was mentioned once on a call.

An onboarding form collapses that into one exchange. It is one of the highest-return forms a service business can build, and one of the least common.

## Ask for what blocks the work

The organising question is not "what would be useful to know" but "what am I unable to start without". Those are different lists, and the second one is much shorter.

For most engagements it comes down to: who is the day-to-day contact, who signs things off, what access do I need, what is the deadline, and where do the existing materials live. Five things. Everything else can be asked once work is underway, when the client is engaged and a reply takes minutes rather than days.

Resist the temptation to make this a discovery document. Discovery is a conversation; onboarding is a checklist.

## Separate the contact from the approver

The single most expensive omission is not asking who approves. Work gets done, sent to the day-to-day contact, and then sits for a week while it travels to someone who was never mentioned.

Two fields — day-to-day contact and approver — surface that in the first hour rather than the third week. If they are the same person, the client answers twice and loses nothing.

## Handle credentials properly

Never collect passwords in a form. Ask instead for the name of the tool and who can grant access, then use that tool's own invitation flow. It is more secure, it survives staff changes, and it avoids you holding credentials you would rather not hold.

For file access, ask for a link to a folder rather than uploads where possible. Clients almost always have the assets somewhere already, and a link stays current when they update it.

## Set the expectation in the form

State what happens after submission and when. "We'll review this and come back within two working days with a kickoff time" prevents the follow-up email asking whether you received it — which, at volume, is a meaningful share of inbox load.

## Make it repeatable

The value compounds when the form is the same every time. A consistent onboarding record per client means you can look back at what was agreed, and it means anyone else on your team can pick up an engagement without interviewing you first.

In Instaform each submission becomes a Contact with the answers attached, and a Deal representing the engagement's stage. New clients arrive already in the pipeline rather than as a folder somewhere. Our [client onboarding questionnaire](/templates/client-onboarding-questionnaire) is a working starting point, and the broader pattern is covered in [CRM pipeline](/crm-pipeline).

## The follow-up form nobody builds

Six weeks in, send a three-question version: is the contact still right, has the deadline moved, is anything blocked. It takes a client ninety seconds and catches the two failure modes — a changed stakeholder and a quietly slipped deadline — while they are still cheap to fix.

Most agencies discover both at the point they become expensive. A short scheduled check-in is the least glamorous form on this list and probably the highest-return one.
