How to Onboard a New Client to Your Influencer Agency (Step-by-Step)
The first 30 days with a new client determine everything.
A smooth onboarding builds trust, sets clear expectations, and positions your agency as the expert. A rough one creates doubt — and doubt is hard to recover from.
This guide gives you the exact step-by-step process to onboard new influencer marketing clients professionally, efficiently, and in a way that sets campaigns up to succeed.
Why Client Onboarding Matters More Than You Think
Most agencies focus all their energy on winning the client. Onboarding is treated as an afterthought — a quick intro call and a shared folder. That is a mistake.
Onboarding is where you:
- Establish how you communicate (and how fast)
- Define what success looks like — before the campaign starts
- Get access to everything you need to actually do the work
- Set boundaries around scope creep
- Show the client what working with a professional agency looks like
Agencies that nail onboarding retain clients longer, get fewer mid-campaign surprises, and receive more referrals. The investment pays back many times over.
The Complete Onboarding Process: Step by Step
Step 1: Send a Welcome Packet (Day 1)
The moment a contract is signed, the client should receive a welcome packet. This is not a boring legal document — it is a confidence builder.
Include:
- A warm personal note from the account lead
- Your agency's contact directory (who handles what)
- Communication norms — response times, preferred channels, meeting cadence
- A timeline of what happens in the first 30 days
- Links to your client portal (where they will review and approve deliverables)
- A simple checklist of what you need from them to get started
This packet signals professionalism immediately. It says: we have done this before, we have a system, you are in good hands.
Step 2: The Kickoff Call (Day 2-3)
This is the most important meeting in the entire engagement. Get it right.
The kickoff call agenda should cover:
- Business goals — not just campaign goals. What does success mean for their brand overall?
- Target audience — who are they trying to reach, and what do they already know about them?
- Brand voice and guardrails — what can and cannot be said or shown?
- Campaign objectives — awareness, conversions, content creation, or community building?
- Past influencer experience — what has worked before? What went wrong?
- Creator preferences — types of creators, niche, audience size, platform priorities
- Approval process — who approves what, and what is the turnaround expectation?
- Reporting — what metrics do they care about? How often do they want updates?
Record the call (with permission). Send a written summary within 24 hours. This document becomes your north star for the campaign.
Step 3: Collect Assets and Accesses (Days 3-5)
Nothing kills momentum like chasing a client for a logo for two weeks. Get everything upfront.
Send a structured asset request covering:
- Brand guidelines (logo files, color codes, font names)
- Approved messaging and key talking points
- Product samples or discount codes (if needed for creators)
- Any existing creator blacklists or preferred roster
- Login access to any shared tools (analytics, tracking links)
- UTM parameters or tracking pixel instructions
- Legal review requirements (do posts need legal sign-off?)
Use a shared checklist they can tick off rather than a long email thread. A client portal with structured intake forms works best here.
Step 4: Build the Campaign Brief
With kickoff notes and assets in hand, build the campaign brief. This is the document that gets shared with creators — so it needs to be clear, complete, and brand-appropriate.
A strong influencer brief includes:
- Campaign overview and objectives
- Target audience description
- Key messages and must-include talking points
- Do's and Don'ts (tone, what not to say, competitor mentions)
- Deliverable specifications (platform, format, length, posting schedule)
- Hashtags, handles, and links to include
- Approval process and timeline
- Payment terms
Send the brief to the client for approval before sharing with creators. This protects you and catches misalignments early.
Step 5: Introduce the Client to Their Portal
If you are using a platform like Truleado, now is the time to walk the client through their portal. This is where they will:
- See campaign progress in real time
- Review and approve creator deliverables
- Download reports and performance data
- Communicate directly with your team
A 15-minute portal walkthrough call prevents 50 support emails later. Show them the approval flow in particular — that is the thing they will use most.
Step 6: Creator Selection and Approval
Present your initial creator recommendations before outreach begins. Clients should see:
- Creator profile overview (niche, follower count, engagement rate)
- Audience demographics data
- Past brand work examples
- Why they are a good fit for this campaign
- Proposed fee and deliverable scope
Before presenting creators to clients, run a quick authenticity check — our guide on how to spot fake followers covers the four red flags agencies should check before any influencer goes on a pitch deck.
Present 3-5 creators per slot, not 20 at once. Fewer options leads to faster decisions. Clients who get overwhelmed with choices delay approvals — which delays everything else.
Step 7: Set Up Campaign Tracking
Before the first piece of content goes live, make sure your tracking infrastructure is in place:
- UTM parameters on all links
- Tracking pixels installed (if applicable)
- Baseline metrics documented (follower counts, engagement benchmarks)
- Reporting template agreed upon with client
- Check-in cadence confirmed (weekly, biweekly, monthly)
Tracking set up after the fact is always incomplete. Do it before launch.
Common Onboarding Mistakes to Avoid
Starting Creator Outreach Before Brief Approval
This is the most common and most costly mistake. If the brief changes after you have already pitched creators, you either have to re-pitch or lock in misaligned deliverables. Always get brief approval first.
Unclear Approval Chains
Vague approvals cause delays. Establish upfront: who has final say? Does content need legal review? What is the SLA for approvals? Document it. Enforce it.
Too Many Stakeholders on the Client Side
Large client teams often have multiple people who want to weigh in on creative. Set a single point of contact for approvals. Feedback by committee is a campaign killer.
No Written Summary After Kickoff
Verbal agreements evaporate. Every important decision from the kickoff call should be documented and sent back to the client for confirmation. If it is not in writing, it did not happen.
Skipping the Portal Walkthrough
Clients who do not understand the tools do not use them. They send approval emails instead, or WhatsApp messages, or call their account manager directly. Walk them through the portal. It saves everyone time.

How Truleado Makes This Easier
Managing all of this manually — across multiple clients simultaneously — is where agencies break down. Things get missed. Emails pile up. Approvals stall.
Truleado centralises the entire onboarding and campaign workflow:
- Client portal: clients approve deliverables with one click — no email chains
- Creator portal: creators receive briefs and submit content in one place
- Campaign workspace: all assets, briefs, and communications in one dashboard per client
- Approval tracking: see exactly where each deliverable is in the approval chain
- Multi-client management: run 20 client onboardings simultaneously without losing track
Agencies using Truleado report cutting their onboarding admin time by more than 60 percent. That is not a marginal improvement. It changes what is operationally possible.
FAQ
Q: How long should client onboarding take?
A: A well-run onboarding takes 1-2 weeks before the first creator outreach begins. Rushing this phase is one of the most common causes of campaign problems later.
Q: What if the client is impatient to get started?
A: Acknowledge the urgency, but hold the process. Explain that a 2-week investment upfront prevents weeks of delays and revisions later. Most clients understand this when it is framed clearly.
Q: How do I handle clients who miss asset deadlines?
A: Build delays into your project timeline from the start. If you need assets by Day 5, tell the client you need them by Day 3. When they miss it, you are still on schedule. Always have a follow-up cadence — a reminder at 48 hours, then 24 hours, then same day.
Q: Should we charge for onboarding?
A: Some agencies bundle onboarding into the setup fee. Others do not charge separately. If your onboarding is thorough and time-intensive (it should be), charging a one-time setup fee of $500 to $2,000 is entirely reasonable. It also filters out clients who are not serious.
Q: What do we do if we discover mid-onboarding that the client has unrealistic expectations?
A: Address it immediately, in writing. Do not wait. Identify the specific gap (timeline, budget, deliverable scope), propose a realistic alternative, and get written agreement. Misaligned expectations that are not corrected during onboarding become client churn at the 3-month mark.
