What a customer onboarding checklist has to cover

A good onboarding checklist is not a list of nice intentions. It is the exact sequence of actions that takes a customer from a signed order form to the first week of real use, written so that anyone on your team could pick it up mid-way and know what comes next.

Most B2B onboarding checklists fail in one of three places. They forget the customer side, so nobody asks for the admin contact or the data export until the week it is needed. They skip sign-offs, so configuration drifts and the customer disputes it at go-live. Or they stop at go-live, so the account lands in customer success without any context about what was promised.

The onboarding checklist template below fixes all three. Every phase has tasks for both sides, every phase ends with a sign-off, and the last phase is a proper handoff. Copy it, delete what does not apply to your product, and add the setup steps that are unique to you.

How to read the template

[Vendor] marks tasks your team owns.
[Customer] marks tasks the customer owns. These are the ones that slip, so they need named owners and dates.
[Both] marks items that need a decision from both teams in the same meeting.
Sign-off lines close a phase. Do not start the next phase until the sign-off is recorded.

Two-sided by design

Roughly a third of the items belong to the customer. Writing them down is what turns a vague kickoff into a schedule both teams can hold each other to.

Phase gates, not one long list

Six phases with a sign-off at the end of each make progress visible to an executive sponsor who never reads the detail.

Ends with the handoff

The checklist does not end at go-live. It ends when customer success has the context they need to keep the account.

The onboarding checklist template

Copy the whole template with the button, then paste it into your document, wiki or project tool. The brackets show the owner of each item.

Customer onboarding checklist

Customer onboarding checklist for [Customer name]
Product or package [Package name], target go-live [Date], onboarding owner [Name]

Phase 1. Before kickoff (days 0 to 3)

[Vendor] Read the signed SOW or order form and list products, seats, integrations and promised dates
[Vendor] Confirm the internal team: onboarding owner, technical lead, executive sponsor
[Vendor] Send the welcome email with the portal link and the kickoff booking link
[Customer] Name the project lead, the technical admin and the executive sponsor
[Customer] Complete the intake form (business goals, current tools, users, constraints)
[Vendor] Review intake answers and prepare questions for kickoff

Sign-off. Contacts named on both sides and intake form complete.

Phase 2. Kickoff (week 1)

[Vendor] Run the kickoff call and walk through scope, phases and target go-live
[Customer] Confirm success criteria in their own words (what does "live" mean for them)
[Both] Agree on the meeting rhythm and the escalation path
[Vendor] Share the dated onboarding plan in the portal within 24 hours of kickoff
[Customer] Approve the plan and the go-live date

Sign-off. Plan and go-live date approved by the customer project lead.

Phase 3. Setup and access (weeks 1 to 2)

[Vendor] Create the customer account, workspace or environment
[Customer] Provide admin users and accept invitations
[Customer] Approve security and access requirements (SSO, IP rules, data residency if relevant)
[Vendor] Configure settings, roles and permissions to the agreed design
[Customer] Upload required documents (signed DPA, W-9 or vendor forms, brand assets)
[Vendor] Record configuration decisions in one shared place
[Customer] Review the configuration in a walkthrough

Sign-off. Configuration approved.

Phase 4. Data and integrations (weeks 2 to 4)

[Vendor] Send the import template and field definitions
[Customer] Export data from the old system into the template
[Vendor] Run a test import and share a validation report
[Customer] Validate a sample of imported records
[Vendor] Connect agreed integrations and test them end to end
[Customer] Confirm integrations behave as expected with real records

Sign-off. Data validated and integrations confirmed.

Phase 5. Training and go-live (weeks 4 to 6)

[Vendor] Run admin training and record it
[Vendor] Run end-user training per team or role
[Customer] Invite all end users and confirm logins
[Both] Agree the go-live checklist and the cutover time
[Vendor] Final data sync and go-live
[Customer] Confirm the first real use (first order, first report, first ticket)

Sign-off. Customer confirms go-live in writing.

Phase 6. Handoff to customer success (weeks 6 to 8)

[Vendor] Hold a hypercare check-in one week after go-live
[Vendor] Write the handoff brief: goals, stakeholders, open risks, promises made
[Vendor] Introduce the customer success manager on a joint call
[Customer] Answer a short onboarding feedback survey

Sign-off. Account owned by customer success.

Onboarding checklist examples for three kinds of B2B companies

The phases stay the same. What changes is the detail inside Setup and Data. Here is how three fictional companies adapt the same onboarding template.

Kestrel Payroll

Payroll software for mid-size employers

Adds customer items for prior payroll registers, tax registration numbers and a parallel run. The go-live sign-off happens only after the first live pay run matches the old system to the cent.

Atlas Dental Group

Practice management rollout across locations

Repeats Phase 5 per clinic. Each location has its own training session and go-live confirmation, so the checklist has a short location block copied once per site.

Quillmere Freight Partners

Logistics services with EDI connections

Expands Phase 4 with trading partner testing. Each partner connection becomes its own item with a customer owner on the partner side and a test document to approve.

Sample onboarding checklist mistakes to avoid

Most teams already have some version of an onboarding checklist. The problems are rarely missing items. They are in how the list is written and kept.

Tasks with no owner

"Set up integrations" is not a task. "[Customer] IT admin grants API access to the CRM" is. Every item needs a person, not a department.

One master file shared by email

A spreadsheet copied for every customer goes stale within a week. Customers cannot see what they owe without asking, and your team cannot see which accounts are slipping without opening every file.

No customer view

If customers only hear about their tasks in meeting notes, they will be late. The fastest onboardings show the customer their own list, with dates, in a place they can reach without a login hunt.

For agencies and consultancies, a lighter version of this list lives on our client onboarding checklist page, and the broader reasoning behind each phase is in the onboarding plan template guide.

From onboarding checklist to a live plan

A checklist template is the starting point. The work is applying it to each new customer: picking the right package, setting the dates from the real kickoff, naming the people on the customer side and chasing them when items are late.

OnboardingCustomers does that part. Save this checklist as a template, then paste a new customer's SOW or order form. The AI onboarding plan reads what was sold, picks the matching template and builds a dated plan with tasks on both sides.

The customer sees only their own items in a branded portal and can tick them off, upload files and sign documents.
Reminders go out automatically when a customer item is late.
Each phase sign-off is recorded with a name and a timestamp.
The handoff brief is drafted from the plan when the account moves to customer success.

Startup includes 10 active onboardings and 20 AI plans per month, and every plan lets you invite as many customer contacts as the project needs.

Frequently asked questions

Still deciding? Write to [email protected] and a person on our team answers.

Is this an employee onboarding checklist?

No. This is a customer onboarding template for B2B companies that sell software or services to other businesses. It covers the steps between a signed contract and a customer who uses what they bought, not hiring or HR paperwork.

How do I adapt the onboarding checklist to my product?

Keep the six phases, then replace the generic tasks with the real steps your implementation team runs. Delete what never happens, add your product specific setup steps, and write the owner of each task in brackets so nobody has to guess.

How long should a customer onboarding checklist be?

Long enough to cover every handover between people and short enough that each item is a real action. For most B2B products that means 25 to 40 items. If a phase has more than ten items, split it or move detail into the task description.

What is the difference between an onboarding checklist and an onboarding plan?

A checklist lists what must happen. A plan adds owners, due dates, dependencies and milestones for one specific customer. Most teams keep the checklist as the reusable template and create a plan from it for every new account.

Can my customers see and tick off their own items?

In a spreadsheet they usually cannot without editing your whole file. In OnboardingCustomers each customer gets a branded portal where they see only their own tasks, upload files, sign documents and tick items off, while your team sees the full checklist.

Turn this checklist into a live onboarding plan

Paste your SOW or your own checklist, and OnboardingCustomers builds a dated plan with a customer portal where the customer ticks off their side.
