Customer Onboarding Roles & Responsibilities (Who Owns What + Template)

Customer onboarding stalls more often over unclear ownership than over any missing feature. Someone assumes the customer will book the kickoff; the customer assumes the vendor will. A technical form sits unfilled because no one on either side was named to fill it. Onboarding is not something a vendor does to a customer – it is a project two organizations run together, and it only moves when every task has a clear owner on the right side of the table. This guide defines the roles on both sides, sets out who is Responsible, Accountable, Consulted, and Informed at each stage, and gives you a roles-and-responsibilities template you can lift straight into your own process.

Who is involved in customer onboarding?

At its simplest, customer onboarding involves two teams. The vendor's team is responsible for guiding the rollout, configuring the product, and proving value; the customer's team is responsible for making decisions, supplying information, and adopting the product internally. Most onboardings that slip do so because one side quietly assumed the other owned a step.

The core roles, across both sides:

• Onboarding manager or CSM (vendor) – owns the onboarding outcome end to end.
• Implementation or solutions engineer (vendor) – owns technical setup, integrations, and data.
• Account executive / sales (vendor) – owns the handoff and the commercial context.
• Support (vendor) – owns issue resolution once the customer is live.
• Executive sponsor (customer) – owns the business outcome and unblocks decisions.
• Champion or project lead (customer) – owns the customer side of the plan day to day.
• End users (customer) – own adoption; they are who onboarding is ultimately for.
• IT / security (customer) – own access, provisioning, and any security review.

The rest of this guide defines each role, then maps them onto a stage-by-stage RACI so it is clear not just who is involved but who owns what, when.

Vendor-side roles

The vendor's job in onboarding is to carry the customer from signed contract to realized value with as little friction and re-explaining as possible. Four roles share that work.

Onboarding manager / CSM

The onboarding manager (sometimes an onboarding specialist, sometimes the customer success manager who will own the account long-term) is accountable for the onboarding outcome. They build and personalize the plan, run the kickoff, keep momentum, coordinate everyone else on this list, and are the single name the customer knows to contact. If onboarding has one owner, it is this person. In smaller teams the CSM plays this role directly; in larger ones a dedicated onboarding manager runs the rollout and hands a live account to the CSM at go-live.

Implementation / solutions engineer

For any product with technical setup – integrations, data migration, SSO, provisioning – an implementation or solutions engineer owns the technical build. They translate what was sold into a working configuration, work directly with the customer's IT, and clear the technical blockers that would otherwise stall a go-live. On low-touch products this role folds into the onboarding manager; on complex B2B software it is a distinct owner.

Account executive / sales

The account executive owns the deal, and their onboarding responsibility is the handoff: transferring why the customer bought, what success looks like, the stakeholders, and any commitments made during the sale – not just tossing an account over the wall. A clean sales-to-CS handoff is the single biggest lever on early time to value, and it is worth treating as its own discipline; we cover it in depth in how to handle the sales-to-customer-success handoff. The AE should stay lightly visible through early onboarding so the relationship feels continuous and commercial questions have an owner.

Support

Support owns issue resolution – the tickets and questions that arise once the customer starts using the product for real. During onboarding their role is usually Consulted or Informed rather than driving, but naming them matters so the customer knows where to go for a bug versus a plan question, and so onboarding-stage issues do not silently become the onboarding manager's overflow.

Customer-side roles

Here is the half most process docs skip. Onboarding has just as many owners on the customer's side, and unassigned customer-side tasks are the most common reason a rollout stalls. Name these people explicitly, ideally at kickoff.

Executive sponsor

The executive sponsor is the senior stakeholder – often the person who signed – who owns the business outcome on the customer side. They rarely do hands-on work, but they unblock decisions, free up their team's time, and keep the project a priority internally. Their most important onboarding contribution is removing obstacles the champion cannot clear alone.

Champion / project lead

The champion is the customer's day-to-day owner of their side of the plan – the counterpart to your onboarding manager. They coordinate their colleagues, complete or delegate customer-side tasks, supply information, and are your main point of contact. A strong, bought-in champion is the best predictor of a smooth onboarding. Watch for a gap the handoff often hides: the person who bought is frequently not the person who has to implement, and the implementing team may not be bought in. When the champion inherited a decision they did not make, expect to spend early onboarding helping them sell it internally.

End users

End users are the people who will actually use the product, and they own adoption – the entire point of onboarding. Even a flawless technical setup fails if the people meant to use the product never change their behavior. Depending on the rollout they are Consulted early (to shape configuration) and firmly Responsible once training and go-live arrive.

IT / security

For anything touching data, access, or compliance, the customer's IT or security team owns provisioning and review – SSO, permissions, security questionnaires, data-processing sign-off. They are easy to forget until a go-live date is a week out and a security review has not started. Identify them at kickoff and give their tasks real due dates, because these are the dependencies most likely to blow a timeline.

The RACI: who owns what, at each stage

A RACI is the standard way to make ownership unambiguous. Each task gets exactly one Accountable owner (the buck stops with them), one or more Responsible doers (they do the work), plus whoever must be Consulted (two-way input) or Informed (kept in the loop). The rule that prevents most confusion: one Accountable owner per task, never two.

Here is a RACI mapped across the four stages of a typical B2B software onboarding. "OM" is the vendor onboarding manager/CSM; "champion" is the customer project lead.

Stage 1 – Handoff & kickoff prep

• Transfer deal context to onboarding: Responsible & Accountable – account executive. Consulted: OM. Informed: champion.
• Schedule and prepare the kickoff: Responsible – OM; Accountable – OM. Consulted: champion. Informed: exec sponsor.
• Identify customer stakeholders and owners: Accountable – champion; Responsible – champion + OM.

Stage 2 – Plan & configuration

• Build and personalize the onboarding plan: Accountable – OM; Consulted: champion (co-create it, don't present it). Informed: exec sponsor.
• Complete intake forms and supply data: Responsible & Accountable – champion; Consulted: OM.
• Technical setup and integrations: Accountable – vendor implementation; Responsible – implementation + customer IT.
• Access, SSO, and security review: Accountable – customer IT/security; Consulted: vendor implementation.

Stage 3 – Training & go-live

• Deliver training: Accountable – OM; Responsible – OM (Consulted: end users).
• Drive user adoption: Accountable – champion; Responsible – end users. Consulted: OM.
• Go-live readiness sign-off: Accountable – OM; Consulted: champion, implementation, IT.

Stage 4 – Handoff to ongoing success

• Confirm value and success criteria met: Accountable – OM/CSM; Consulted: exec sponsor.
• Transition to ongoing support: Accountable – CSM; Informed: support, champion.

You can slice the stages differently for your product, but keep the discipline: every row has one Accountable owner, and customer-side rows are named just as clearly as your own.

Where onboarding handoffs break – and how to prevent it

Even a clean RACI breaks at the seams between owners. The usual failure points:

• The sales-to-onboarding gap. Context dies at the contract. Prevent it with a structured handoff, not a verbal one – see the handoff guide.
• Unnamed customer-side owners. "The customer" owns a task, but no specific person does, so it slips. Fix: assign customer tasks to a named individual, not an organization.
• The champion bottleneck. Everything routes through one overloaded champion. Fix: distribute customer-side tasks to the right people (IT, end users, sponsor) instead of stacking them all on the champion.
• Invisible ownership. Owners are agreed in a kickoff, then live only in someone's memory or a static doc that goes stale. Fix: keep ownership visible where the work actually happens.

That last point is the crux. A RACI written in a slide deck is accurate for exactly one day. Ownership only holds if it lives in the plan both sides work from – which is where the tooling matters.

A customer onboarding roles & responsibilities template

Use this as a starting template. Adapt the roles to your product and rollout size, then assign a real person to each before kickoff.

Vendor side

• Onboarding manager / CSM – Accountable for the onboarding outcome; owns the plan, kickoff, momentum, and coordination.
• Implementation / solutions engineer – owns technical setup, integrations, and data migration.
• Account executive – owns the sales-to-onboarding handoff and commercial context; stays looped in early.
• Support – owns issue resolution from first use onward.

Customer side

• Executive sponsor – owns the business outcome; unblocks decisions and frees up time.
• Champion / project lead – owns the customer side of the plan day to day; main point of contact.
• End users – own adoption; consulted early, responsible at training and go-live.
• IT / security – own access, provisioning, and security review.

The three rules that make it work

1. One Accountable owner per task – never two.
2. Every customer-side task is assigned to a named person, not "the customer."
3. Ownership lives in the shared plan both sides can see, not in a doc that goes stale.

For the plan those owners actually work from, pair this with our free customer onboarding plan template, and set the roles live at your onboarding kickoff call.

Assign owners on both sides in one shared plan

A roles chart is only as good as its visibility. The reason ownership erodes is that most onboarding plans live in an internal tool – Monday, Asana, Notion, a spreadsheet – that the customer never opens. So customer-side owners never see their tasks, and "who owns what" collapses back onto the vendor to chase manually. Internal project tools were built for internal teams; they have no seat for the customer, which is exactly the half of the RACI that stalls.

The fix is to run onboarding in a space both sides work in, with tasks assigned to owners on both sides. This is what a purpose-built customer onboarding platform is for. In Valuecase, each customer gets their own branded Space – one login-free link they open to find the shared onboarding plan, their tasks, forms, and resources in one place. Because it is a shared plan, you assign tasks not just to your own team but to the customer's stakeholders too: the champion, IT, an end user. Each owner sees exactly what is theirs, and automated reminders chase the customer's owners on their open tasks so accountability does not depend on you sending another follow-up email. Your team watches progress across every account from a central dashboard, with engagement tracking that flags the accounts going quiet before a due date slips – the tell-tale of an owner who has gone dark. For the wider playbook on running the project this way, see how to manage customer onboarding projects together with your clients.

Setting the plan up is fast, and AI does most of the assigning for you: the create an implementation plan use case drafts a tailored plan with owners from your template, and the chase customers workflow nudges the right owner with context when a task goes overdue.

FAQ

Who is responsible for customer onboarding?

On the vendor side, an onboarding manager or customer success manager (CSM) is accountable for the onboarding outcome end to end – they own the plan, the kickoff, and coordination across implementation, sales, and support. But onboarding is a two-sided project: the customer's champion or project lead is equally responsible for their side of the plan, with an executive sponsor owning the business outcome, end users owning adoption, and IT owning access and security. The cleanest setups name one accountable owner per task on both sides.

What does an onboarding manager do vs a CSM?

They overlap, and in smaller teams they are the same person. An onboarding manager (or onboarding specialist) owns the rollout – getting a new customer from signed contract to live and getting value, typically over a defined onboarding window. A CSM owns the ongoing relationship – adoption, retention, and renewal over the whole customer lifetime. In larger organizations the onboarding manager runs the initial project and hands a live account to the CSM at go-live; in smaller ones the CSM runs onboarding themselves and simply continues with the account afterward.

What is the customer's role during onboarding?

The customer is a co-owner of the project, not a passive recipient. Their executive sponsor unblocks decisions and keeps onboarding a priority; their champion or project lead runs the customer side of the plan day to day and is the main point of contact; their end users adopt the product; and their IT or security team owns access, provisioning, and any security review. The most common cause of a stalled onboarding is a customer-side task with no named owner – so assign these roles explicitly at kickoff.
