What Is a Client Welcome Packet?
A client welcome packet is the client-facing document you send right after a new client signs, setting out who they will work with, how you will communicate, what happens next, and what you need from them. It is the difference between a new client feeling confident and organized in week one, and feeling unsure whether they made the right choice.
It is not the same as your internal onboarding checklist, which is the process you run behind the scenes. The welcome packet is what the client actually sees.
What to Include in a Welcome Packet
Keep it warm, short, and useful. Six sections do the job:
- Your team, who they will work with and who to contact.
- How we work together, channels, response times, and meeting cadence.
- What happens next, the first milestones and dates.
- What we need from you, assets, access, and approvals, with due dates.
- Billing, how and when you invoice and how they pay.
- Questions, who to ask and how.
The Welcome Packet Template
Copy this, make it sound like you, and send it the day the contract is signed.
We are thrilled to be working with you on [project or engagement]. This packet covers everything you need to know to get started, so the first week is smooth.
[Names, roles, and photos of who the client will work with, and who their main point of contact is.]
[Your communication channels, response times, meeting cadence, and where work and files live. For example: weekly check-in on Mondays, replies within one business day, everything in your client portal.]
[The first milestones and dates, so the client knows the plan. For example: kickoff call this week, first draft in two weeks, review, launch.]
[Assets, access, approvals, and information you need from the client to start, with a due date for each. This is the section that prevents the first delay.]
[How and when you invoice, payment terms, and how they pay. For example: monthly invoice on the 1st, due within 14 days, pay online by card or bank transfer.]
[Who to contact for anything, and how. Reassure them there are no silly questions.]
The fastest win is section 4
The single biggest cause of a slow, frustrating first week is waiting on the client for assets, access, or approvals. Spell out exactly what you need, with a due date for each item, and you remove the most common early delay before it happens.
How to Deliver the Welcome Packet
Send the packet the moment the contract is signed, while the client is most excited. A polished welcome sets the tone for the whole relationship and quietly signals that you are organized and easy to work with, which is a real factor in retention.
In AgencyKit, each client gets a branded client portal where the welcome details, files, invoices, and project progress live in one place, so the client always knows where to look instead of digging through email.
