The first 90 days decide whether a new eCommerce leader stays and succeeds or quietly starts looking. A strong onboarding plan has four phases. Before day one: grant full platform access, write down the top three priorities, and share the budget, forecast, and agency contracts. Days 1 to 30: the leader learns the business through one-on-ones, data, and audits, and avoids big changes. Days 31 to 60: the leader turns that diagnosis into a plan the executive team agrees on, and delivers one or two early wins. Days 61 to 90: the leader makes the first team and agency decisions and completes a formal 90-day review. The CEO or hiring manager should meet with them weekly throughout. Most early exits trace back to a gap between the role as sold and the role as it is, and the first 90 days are when that gap is easiest to close.
Companies put enormous effort into hiring an eCommerce leader. They define the role, run the search, interview carefully, check references, and work hard to close the candidate after the offer. Then, too often, the effort stops. The new leader gets a laptop, a few introductions, and a long list of problems, and everyone assumes the hard part is over.
It is not. The stretch between the start date and the end of the first quarter is where many leadership hires are won or lost. A leader who feels set up to succeed in those 90 days usually stays for years. A leader who runs into surprises, unclear priorities, and missing support often starts updating their LinkedIn profile before month six.
This plan covers that stretch. It pairs well with our post on the best reference check question, which is designed to help you support a new hire from the very first week.
Why New eCommerce Leaders Leave Early
A new leader can handle a hard job. What wears them down is discovering, week after week, that the budget is smaller, the team is thinner, the decision rights are narrower, or the founder is more involved than anyone said during the interviews.
The most common causes we see:
- Scope surprises. Channels, teams, or budgets turn out to be different from what was described.
- Unclear decision rights. The leader does not know what they can decide alone and what needs approval.
- Missing resources. Tools, data, or headcount the leader expected are not there.
- Misalignment with the CEO or founder. Different views on priorities that were never discussed openly.
- No feedback loop. The leader has no regular forum to raise problems before they become reasons to leave.
Every one of these can be prevented or caught early with a structured plan. Our post on selling the role without overselling it covers how to reduce these gaps during the interview process. This plan picks up where that one leaves off.
Before Day One: Set Up the Leader to Start Fast
The first impression of the job is set before the leader arrives. Use the notice period to get the basics in place.
| Task | Why It Matters |
|---|---|
| Grant admin access to every platform, marketplace, ad account, and analytics tool | Nothing slows a new leader down like waiting two weeks to see the data |
| Write down the top three priorities for the role | Gives the leader and the executive team a shared starting point |
| Share the budget, forecast, and agency contracts | Lets the leader arrive understanding the money and the commitments |
| Define decision rights in writing | Prevents confusion about what they own versus what needs approval |
| Schedule introductions with key internal partners and external partners | Builds relationships with finance, operations, agencies, and retail contacts early |
| Tell the team who is starting and what they will own | Reduces anxiety and sets up a smoother first week |
If the role is replacing someone who left, our 30-day plan for when a Head of eCommerce resigns covers how to capture a handoff document. Give it to the new leader on day one.
Days 1 to 30: Learn the Business
Goal: Understand Before Changing
Listen, learn, and build relationshipsThe first month is for learning. Strong leaders resist the urge to make big changes before they understand why things work the way they do. That restraint builds credibility with the team and prevents expensive mistakes.
- One-on-ones with every direct report. What is working, what is not, and what they need.
- Meetings with key partners. Finance, operations, product, marketing, and the agencies and retail contacts who matter most.
- A walk through the P&L and data. Channel performance, margins, customer metrics, and how reporting works today.
- Platform and agency audit. What tools are in place, what each agency does, and what each one costs.
- Customer exposure. Reviews, customer service tickets, and the full purchase experience on every channel.
End-of-month milestone: a short written diagnosis. What the leader learned, the biggest opportunities and risks, and the questions they still need answered. The hiring manager should read it and discuss it in person.
Days 31 to 60: Agree on the Plan
Goal: Turn Diagnosis Into Direction
Priorities, metrics, and early winsThe second month is about alignment. The leader turns what they learned into a plan, and the executive team agrees on it. This is the moment to surface any disagreement about priorities, before it turns into frustration.
- A written 6- to 12-month plan. Priorities, key projects, resource needs, and the metrics that will define success.
- Executive alignment. A working session with the CEO and key peers to agree on the plan and the tradeoffs.
- One or two early wins. Visible, low-risk improvements that show progress and build trust, such as fixing a broken report, cleaning up an underperforming campaign, or resolving a long-standing site issue.
- Resource requests. A clear case for any headcount, budget, or tools the plan requires.
End-of-month milestone: an approved plan with agreed metrics. If the plan and the executive team's expectations do not match, this is the cheapest time to find out.
Days 61 to 90: Start Executing
Goal: Move From Planning to Results
Team decisions, launches, and the 90-day reviewBy the third month, the leader should be acting with confidence. They make the first structural decisions and start the projects that will define their first year.
- First team decisions. Role changes, open headcount, and any performance issues on the team.
- Agency and vendor decisions. Which partners stay, which change scope, and which get replaced.
- Launch priority projects. The two or three initiatives from the agreed plan.
- A formal 90-day review. A structured conversation with the hiring manager covering what is working, what is missing, and what comes next.
The 90-day review is not a performance review. It is a check on whether the company has given the leader what they need, and whether the role still matches what was promised.
The 90-Day Plan at a Glance
| Phase | The Leader's Focus | The Company's Job | Milestone |
|---|---|---|---|
| Before day one | Review materials shared in advance | Access, priorities, budget, decision rights, introductions | Leader arrives ready to work |
| Days 1 to 30 | Learn the business, team, data, and partners | Make time, answer questions, avoid pushing for quick changes | Written diagnosis |
| Days 31 to 60 | Build the plan and deliver early wins | Engage in planning and agree on priorities and metrics | Approved plan |
| Days 61 to 90 | Make team and agency decisions, launch projects | Support decisions and approve resources | Formal 90-day review |

Warning Signs to Watch For
Weekly check-ins between the CEO or hiring manager and the new leader are the best early warning system. Watch for:
- Repeated surprises. The leader keeps discovering things about the role, budget, or team that were not discussed.
- Decisions stalling. Proposals keep getting delayed, overruled, or sent back for more analysis.
- Silence. A leader who stops raising problems may have stopped expecting them to be fixed.
- Tension with a key peer or the founder. Especially if it is not being addressed directly.
- A widening gap between interview and reality. The leader starts saying "that is not what I was told."
Any of these deserves a direct conversation, quickly. Most are fixable in month two. By month eight, they are usually a resignation. Our post on the true cost of a bad eCommerce hire shows why early intervention is worth the effort.
Adjust the Plan for the Hire's Background
Not every new leader needs the same onboarding. A few common adjustments:
- Enterprise leader joining a smaller brand. Be explicit early about resources and what they will need to do hands-on. Our post on enterprise leaders at a $20M brand covers the risks.
- Agency-side hire moving in-house. Prioritize P&L, margin, inventory, and internal relationships in the first month. See our post on hiring agency-side candidates.
- Internal promotion. They know the business, but they need help redefining relationships with former peers and stepping back from execution.
- First eCommerce leader at the company. Spend more time educating the executive team on what eCommerce needs. Our post on who should own eCommerce is useful context.
What Happens After 90 Days
Onboarding does not end on day 90, but the structure can loosen. Many companies move from weekly to biweekly check-ins, review progress against the plan each quarter, and start thinking about the leader's development. Our guides on how to retain eCommerce talent and developing eCommerce leaders cover the longer term.
Frequently Asked Questions
What should a new eCommerce leader do in the first 90 days?
In the first 30 days, a new eCommerce leader should learn the business: meet every direct report and key partner, study the P&L and data, and audit platforms and agencies. In days 31 to 60, they should turn that diagnosis into a plan agreed with the executive team and deliver one or two early wins. In days 61 to 90, they should make the first team and agency decisions, launch priority projects, and complete a formal 90-day review.
Why do new eCommerce leaders leave in their first year?
The most common reasons are a mismatch between the role as sold and the role as it really is, unclear priorities or decision rights, missing resources such as budget, team, or tools, poor alignment with the CEO or founder, and a lack of early support or feedback. Most of these show up in the first 90 days and can be fixed if someone is watching for them.
What should a company prepare before a new eCommerce leader starts?
Before day one, the company should set up admin access to every platform and ad account, write down the top three priorities for the role, share the current budget, forecast, and agency contracts, schedule introductions with key internal and external partners, and tell the team who is starting and what they will own.
How often should a CEO meet with a new eCommerce leader?
Weekly for the first 90 days is a good standard. A short, consistent check-in on progress, blockers, and what the leader is learning builds trust and catches problems early. After the 90-day review, many companies move to every other week.
What are the warning signs that a new eCommerce leader might leave?
Common warning signs include repeated surprises about scope or resources, decisions that keep getting overruled or delayed, a leader who has stopped raising problems, tension with a key peer or the founder, and a growing gap between what was promised in the interview and what the job actually involves. Any of these is worth a direct conversation before it becomes a resignation.
