What our first 90 days with a new client actually look like

Client onboarding is where most agency relationships quietly succeed or quietly fail. The first 90 days of working with a new client are not a grace period — they are the period. At Choco Media, client onboarding shapes everything that follows: how well we understand the business, how quickly we earn trust, and whether the work we deliver actually moves the right numbers. This post is a behind-the-scenes account of how those first three months unfold, what happens in each phase, and why we have structured it the way we have.

This is written for business owners and marketing leads who are either considering working with an agency or have just signed with one and want to know what “good” looks like. The specifics here describe our process, but the underlying logic applies broadly. Knowing what to expect from a well-run client onboarding process makes you a better counterpart — and that benefits everyone.

We have also written this because onboarding is one of the most under-documented parts of agency work. There is no shortage of content about strategy and tactics, but relatively little about the operational reality of getting a new relationship off the ground well. We want to change that, at least from our corner.

Why the First 90 Days Are Not About Quick Wins

There is pressure, on both sides, to show results fast. Clients want to feel the spend was justified. Agencies want to prove their value before the contract review. We understand this pressure and we do not ignore it — but we also do not let it distort the work.

The first 90 days are primarily a diagnostic and foundation phase. If we skip proper discovery to chase a quick win, we often end up optimising the wrong thing. A landing page conversion rate looks good on paper, but if the traffic quality is poor, improving the page only slightly reduces a deeper problem. A social campaign gets early engagement, but if the brand voice is not yet defined, we are building an audience around messaging we might change in month four.

• Quick wins that contradict the long-term strategy create technical debt
• Rushing past discovery means we miss constraints that matter later
• Trust built slowly through transparency outlasts trust bought with early vanity metrics
• The first 90 days set the communication norms for the entire relationship

That said, we do aim to have at least one concrete deliverable in the client’s hands within the first three weeks. This is not a quick win for optics — it is a shared artefact that gives us something real to discuss, revise together, and learn from.

Month One: Discovery, Access, and the Listening Phase

The first month is almost entirely inbound. We ask a lot of questions, read a lot of background material, and try to understand the business before we start forming opinions about it.

The Onboarding Call

Within the first three days we hold a structured onboarding call — typically 90 minutes. The agenda is fixed: business model, revenue streams, competitive landscape, current marketing channels, what has worked, what has not, and what the client considers their biggest constraint right now. We record it with permission and use the transcript as a reference document throughout the engagement.

We ask clients to tell us about a campaign or piece of content they were genuinely proud of, and one they would redo. Both are more useful than any brief.

Access and Asset Collection

We collect access to analytics, ad accounts, CMS, and any relevant tools in week one. We do this early not because we need everything immediately, but because access requests that linger past week three are a signal that something in the relationship is fragile. Smooth access handover is a small but meaningful indicator of trust.

• Google Analytics / GA4
• Google Search Console
• Meta Business Manager and Google Ads (where applicable)
• CMS or website backend
• Brand assets: logos, fonts, brand guidelines if they exist
• Any prior agency reports or strategy documents

The Audit

By the end of week three, we complete a channel audit across the areas in scope. This is not a full technical audit of everything — it is a diagnostic focused on finding the three to five things most likely to move the needle. We share this in a written document, not a slide deck, because we want the client to be able to refer back to it, annotate it, and use it as a checklist rather than a presentation to sit through once.

The best audits we have done were ones where the client told us: “we already suspected this, but nobody had put it in writing before.” Naming what everyone privately knows is often the most useful thing an outside eye can do.

The Strategy Document: What It Contains and Why It Takes Time

At the end of month one, we deliver a strategy document. This is the most important output of the first 90 days and we invest heavily in getting it right. It contains our read of the business, the market, the current marketing situation, and the priorities we recommend for the engagement.

Writing it takes time because it requires us to have formed genuine opinions — not just summarised what the client told us in the onboarding call. We cross-reference the audit findings with what we know about the category, what we see in the data, and what competitors are doing. We then make specific recommendations with reasoning, not a menu of options.

• A summary of what we found in the audit, including the uncomfortable parts
• Our interpretation of the core growth constraint
• 3-5 prioritised recommendations for the next six months
• What we will not do, and why
• How we propose to measure progress

Clients sometimes push back on items in the strategy document. We welcome this. A strategy that survives a push-back conversation is stronger for it. What we do not do is soften findings to avoid discomfort — that produces documents that feel good to receive and are useless to act on.

For clients on our bespoke retainer, the strategy document also defines the working rhythm for the whole engagement: what we will review monthly, what the escalation path looks like, and how we handle changes in direction mid-engagement.

Month Two: First Work in Production

Month two is when we start building. The specific deliverables depend on the engagement scope, but the pattern is consistent: start with one thing, do it properly, and use the feedback loop to calibrate before expanding.

Content and Messaging Work

If content is in scope, month two typically begins with a messaging framework and the first two or three pieces of content. The messaging framework is not a brand book — it is a working document that answers the questions writers and strategists need to answer quickly: what claims can we make, what tone do we use, what does the ideal reader already believe when they arrive, and what do we want them to believe when they leave.

First content pieces are written to spec but treated as tests. We review them together, mark what landed and what did not, and update the framework accordingly. By the third piece, the calibration is usually solid. Our AI content creation process relies on this framework being in place before we scale — without it, volume without direction produces noise.

Paid Media

If paid media is in scope, month two starts with account structure review or setup, audience definition, and the first test campaigns. We do not launch with full budget in month two. We use a smaller allocation to test creative hypotheses before scaling what works. In client work we have found that agencies who launch full-budget in week one are optimising for impressive-looking spend reports, not results.

• Week 5-6: account structure, pixel/tracking verification, first creative brief
• Week 7: first campaigns live at reduced budget
• Week 8: first data review, creative iteration decisions

The Month Two Check-In: An Honest Conversation

At the end of month two, we hold a check-in call with a specific agenda. This is not a status update — it is a deliberate pause to ask whether the engagement is on track in ways that numbers alone do not show.

We ask the client directly: is the communication working for you, are you getting the right level of visibility into our work, and is there anything we said we would do that has not happened yet? We ask ourselves the same questions internally beforehand. If something is not working at week eight, addressing it then is far better than letting it become a pattern.

We also revisit the strategy document at this point. In eight weeks, something has usually changed — a competitor move, a product update, a shift in the client’s priorities. The strategy document should reflect the current reality, not the reality of the onboarding call.

Month Three: Building the Rhythm

By month three, the discovery phase is complete and the early test phase is wrapping up. The goal of month three is to establish the working rhythm that will carry the engagement forward: predictable cadences, clear ownership, and a feedback loop that requires minimal overhead to maintain.

Reporting

We set up reporting in a format that the client will actually use. This means asking, not assuming. Some clients want a monthly written report. Others want a live dashboard they can check themselves. Others want a brief Loom video walking through the numbers. We have our own preferences around what makes a good report, but the format that gets read and acted on is always better than the format that is technically comprehensive but ignored.

We document our reporting setup in Notion, which serves as the connective tissue for client work — briefs, content calendars, research notes, and feedback threads all live there. If you are curious about how we organise this, we wrote about it in detail in why we built our content engine in Notion.

Handoff of Repeatable Processes

Any process that will run regularly — content approval workflows, ad creative review cycles, monthly reporting — gets documented in month three so that it does not depend on one person on either side remembering how it works. This documentation is not elaborate; it is a checklist and a responsible-party column. But it means that when someone is on holiday or changes roles, the process continues.

• Content calendar and approval workflow
• Ad creative brief → review → launch cycle
• Monthly reporting cadence and format
• Escalation path for urgent requests
• How we handle scope changes mid-engagement

What the 90-Day Review Looks Like

At the end of month three, we hold a formal 90-day review. The agenda has three parts: what has been delivered against the strategy document, what the data shows so far, and what we recommend adjusting going into the next quarter.

We share this in writing before the call so the client can read it, form their own views, and come to the conversation ready to discuss rather than absorb. The written document becomes part of the client’s record — something they can reference when explaining the engagement internally or briefing in new stakeholders.

The 90-day review is also where we surface anything we got wrong in the strategy document. In our experience, the original strategy is roughly right about the big picture and occasionally wrong about a specific tactic or priority. Naming this openly, with the updated view, is more useful than quietly adjusting without acknowledgment. It also builds the kind of trust that makes long engagements work.

What Makes Client Onboarding Go Wrong

Having run this process across a range of clients and sectors, we have a reasonably clear picture of the failure modes. They are almost always relational rather than technical.

• Delayed access. When clients take more than two weeks to share analytics or ad account access, it usually signals unclear internal ownership. We flag this early and offer to help resolve it.
• Scope drift in month one. Before the strategy is agreed, ad hoc requests can pull the team in multiple directions. We hold a soft boundary on new requests until the strategy document is signed off.
• Over-promising during sales. If commitments made in the pitch do not match what the onboarding process can deliver, month two becomes about managing expectations rather than doing work. We try to keep the pitch and the onboarding closely aligned.
• Skipping the month two check-in. This call feels optional when things are going well. It is most necessary precisely when things are going well, because that is when small misalignments go unnamed longest.
• Reporting that nobody reads. A comprehensive report sent to an inbox that nobody monitors is worse than no report, because it creates the illusion of oversight without the reality.

What Good Looks Like at Day 90

At the end of a well-run first 90 days, a few things should be true. The client understands what we are doing and why. We have a tested and documented working rhythm. The strategy is grounded in real data rather than assumptions from the onboarding call. There is at least one concrete result we can point to, even if it is early. And both sides have had at least one direct conversation about something that was not working and adjusted accordingly.

That last one matters more than people expect. A relationship that has navigated its first difficulty is fundamentally more robust than one that has only had easy months. The first 90 days are not just about delivering work — they are about building the kind of working relationship that can handle the harder months that follow.
