A client onboarding checklist is the list of documents, signatures, access, and answers you need from a new client before real work can start. The core is the same everywhere: a signed agreement, a way to get paid, someone who can approve things, and the inputs you need to do the job. After that, every industry adds its own must-haves. An accountant needs prior returns. A personal trainer needs a PAR-Q. An architect needs a boundary survey.
This page gives you both. Start with the universal checklist, then jump to your industry for the specific documents to request.
The universal client onboarding checklist
These eight items apply to almost every service business. If you only fix these, onboarding already gets faster.
- Signed agreement. Scope, fees, timeline, cancellation terms. Nothing starts before this is countersigned.
- First payment or deposit. Collected, not just invoiced.
- Legal and billing details. Legal entity name, billing address, tax ID or W-9, and the billing contact.
- Named decision-maker. One person whose approval is final, in writing. Most stalled projects trace back to an approver nobody knew about.
- Intake questionnaire. Goals, context, constraints, and what “done” looks like in their words.
- Documents and data you need to do the work. This is the industry-specific part (see below).
- Access to systems. Software logins, shared folders, or accounts you’ll work in. Ask for delegated or read-only access, never shared passwords.
- Communication setup. Preferred channel, response-time expectations, meeting cadence, and the kickoff date.
Want the emails that go with it? Use our client onboarding email templates for the welcome, the document request, and the reminders. If you prefer to collect answers in one form, start from the client intake form template.

Financial services
Accounting client onboarding checklist
- Signed engagement letter (scope, fees, term, termination)
- Government-issued ID for each authorized signer
- Articles of incorporation or formation documents
- EIN confirmation letter (IRS CP 575) or W-9
- Federal and state tax returns, last 2 to 3 years if you’re taking over from another preparer
- Prior-year balance sheet, P&L, and cash flow statement
- Chart of accounts and trial balance exported from the previous system
- Last 12 months of bank and credit card statements for every account
- Payroll reports: last 4 quarters of 941s, W-2s, and 1099s issued
- Loan documents and amortization schedules
- Sales tax registrations and recent returns
- IRS Form 8821 or 2848 so you can talk to the IRS for them
Watch out: the requirements change by entity. An individual 1040 client doesn’t need formation docs, while an S-corp needs payroll reports too. Build one template per client type instead of sending everyone the full list. Re-collect the engagement letter and any expired IDs every year.
Bookkeeping client onboarding checklist
- Signed engagement letter with the monthly close timeline
- ID for every signer (required if you touch bill pay or payroll)
- EIN letter or W-9
- Accountant-level access to QuickBooks Online, Xero, or their current software
- Read-only bank feeds for every operating, savings, and merchant account
- Read-only access to business credit cards
- Last 12 months of bank and card statements
- Prior-year financial statements and most recent tax return
- Chart of accounts and opening trial balance
- Vendor list with W-9s for anyone paid $600+ (see how to collect W-9 forms from vendors)
- Customer list and open AR aging
- Payroll processor access and recent registers
- List of recurring transactions and subscriptions
Watch out: ask for bank feeds, not statement PDFs, whenever possible. Statements are for reconciling the opening balance; feeds are what keep the monthly close on schedule.
Fractional CFO client onboarding checklist
- Engagement letter and NDA
- Formation documents, operating agreement or bylaws
- Cap table plus every SAFE, convertible note, and option grant
- Last 24 months of financial statements and the current trial balance
- Access to the accounting system and bank feeds
- Debt agreements, credit lines, and covenants
- Revenue data: customer list, contracts, MRR or pipeline report
- Payroll register and headcount plan
- Most recent board deck and investor updates
- The KPIs the founder and board actually look at, and the reporting cadence they expect
Watch out: founders forget instruments. Ask directly: “Have you signed any SAFE, note, or side letter that isn’t in the cap table?” A missed conversion term can wreck your first model.
Insurance agent client onboarding checklist
- Signed broker of record or agent of record letter
- Photo ID for every named insured
- Motor vehicle record (MVR) authorization
- Declarations pages for every active policy
- 5-year loss runs from each current carrier (required for commercial)
- Driver and vehicle list with license numbers and VINs
- Property details: year built, square footage, roof age, updates
- Four-point or wind mitigation inspection where relevant
- Mortgagee information
- Business formation documents and payroll or revenue by class code for commercial lines
- Certificate of insurance requirements from the client’s landlords or customers
- Signed application and coverage acknowledgments
Watch out: loss runs take carriers days or weeks to issue. Request them on day one, and track them separately from what the client sends you. For recurring certificates, see certificate of insurance tracking.
Agencies, consultants, and freelancers
Marketing agency client onboarding checklist
- Signed MSA and statement of work, plus DPA if you’ll handle customer data
- Brand guidelines, logo files, fonts, color codes, and tone-of-voice notes
- Delegated access to ad accounts (Google Ads, Meta Business Manager, LinkedIn)
- Access to GA4, Search Console, tag manager, CRM, and email platform
- CMS or website access
- Ideal customer profile, personas, and top competitors
- Required legal disclaimers and claims the client can’t make (critical in finance, health, and legal)
- Reporting preferences: which metrics, what format, how often
- Main contact, approver for creative, and approver for spend
- Goals and targets for the first 90 days
Watch out: get access through business manager or partner invites, never the client’s personal login. When the relationship ends, access comes back cleanly.
Web design client onboarding checklist
- MSA or SOW with revision rounds, milestones, and a kill fee clause
- Deposit (usually 30 to 50 percent) and payment schedule
- IP and ownership terms for final files and source code
- Discovery brief: business, audience, site goals, success metrics, current pain points
- Page inventory and sitemap draft
- Brand assets and any photography they own
- Copy owner: who writes it, and when it’s due
- Domain registrar, DNS, hosting, and current CMS access
- Analytics and Search Console access, plus the list of URLs that need redirects
- Third-party tools to integrate: booking, CRM, payments, forms
Watch out: missing content is the number one cause of blown launch dates. Put the copy deadline in the contract and track it like any other deliverable.
Consulting client onboarding checklist
- Signed engagement letter, SOW, and NDA
- Stakeholder map: sponsor, decision-makers, day-to-day contact, people you’ll interview
- Org chart and current strategy documents
- Relevant financial data for the scope (budget, P&L by unit, cost data)
- Access to the systems and data sources you’ll analyze
- Prior reports, audits, and consultant deliverables on the same topic
- Project management and communication setup
- Written success criteria: what decision or outcome the engagement should produce
Watch out: ask for prior work early. Clients often commissioned a similar study two years ago, and reading it saves you a week of discovery.
MSP and IT client onboarding checklist
- Signed MSA, SLA, and acceptable use policy
- Company contacts, escalation list, and authorized requesters
- Network documentation: ISP details, firewall, switches, Wi-Fi, IP ranges
- Server and endpoint inventory with OS versions and warranty dates
- Admin credentials shared through a password vault, never email
- Backup and disaster recovery status, including the last successful restore test
- Security baseline: MFA status, EDR, patching, recent incidents
- Line-of-business applications and their vendor contacts
- Microsoft 365 or Google Workspace tenant admin access
- Handoff documentation from the previous provider
Watch out: “we have backups” is not evidence. Ask when the last restore was tested, and document the answer before you take responsibility for the environment.
Freelance client onboarding checklist
- Signed contract with scope, revision rounds, and payment terms
- Deposit paid
- Company and billing details: legal name, tax ID, billing email
- Day-to-day contact and final approver
- Brand assets: logos, guidelines, fonts, colors
- Access to the tools you need for the work
- 3 to 5 reference examples they like and 1 or 2 they don’t
- Existing content, data, or research to build on
- NDA and DPA if required
Watch out: freelancers lose the most time to scope creep. Send the checklist and the contract together, so the client agrees to the inputs and the scope at the same time.
SaaS customer onboarding checklist
- Before kickoff: signed order form, named admin, and the customer’s stated success criteria
- Discovery: current process, tools being replaced, integration requirements, security questionnaire
- Setup: SSO configuration, user list for provisioning, data files for import, integrations connected
- Activation: training sessions booked, first workflow live, check-in scheduled at day 30
Watch out: the security questionnaire and DPA often sit with the customer’s legal team for weeks. Send them before kickoff, not after.
Architecture and interior design
Architect client onboarding checklist
- Owner-architect agreement (AIA B101 or your firm’s equivalent)
- Fee proposal with phase breakdown and retainer invoice
- Reimbursables and additional-services rate sheet
- Legal owner of record and proof of signature authority for LLCs or trusts
- Boundary and topographic survey
- Title report, easements, and deed restrictions
- Zoning verification and HOA design guidelines
- Existing drawings, as-builts, and prior permits
- Geotechnical report if available
- Program: spaces, sizes, adjacencies, and must-haves
- Budget and target schedule
- Names of every approver, including lenders and HOA boards
Watch out: an outdated survey can invalidate a full schematic design. Confirm the survey date and who prepared it before drafting starts.
Interior designer client onboarding checklist
- Letter of agreement with scope, phases, and revision rounds
- Fee structure disclosure (flat, hourly, cost-plus) and retainer
- Trade discount, markup, and purchasing terms
- Freight, receiving, and warehousing terms
- Change order and cancellation policies
- Household brief: who lives there, pets, how each room is used
- Style references and pieces they’re keeping
- Budget worksheet by room
- Floor plans, measurements, and photos of existing conditions
- Building rules for deliveries and contractors (condos and co-ops)
- Photography and publication rights
Watch out: clarify who holds the merchant account and when orders become non-cancellable. Most designer-client disputes are about purchasing, not taste.
Coaching, fitness, and event services
Coaching client onboarding checklist
- Welcome email confirming the package and next steps
- Signed coaching agreement: sessions, cancellation, refunds, confidentiality
- First payment collected
- Intake questionnaire: background, goals, current challenges
- Baseline assessment (wheel of life, DISC, CliftonStrengths, or your own)
- Scheduling link with real availability
- Pre-work before session one
- Preferred channel between sessions
- NDA or confidentiality addendum for executive and business coaching
Watch out: health and nutrition coaches may be collecting health data. Keep it out of email and store it somewhere with access controls. Our guide to HIPAA-compliant document collection covers the basics.
Personal trainer client onboarding checklist
- Signed training agreement: package, cancellation, and no-show policy
- Liability waiver and informed consent, signed before any assessment
- PAR-Q+ readiness questionnaire
- Medical history: injuries, surgeries, conditions, medications
- Physician clearance if the PAR-Q+ or history flags a risk
- Emergency contact
- Payment method on file
- Goals and lifestyle questionnaire
- Separate consent for progress photos and measurements
- Availability, equipment access, and training preferences
Watch out: the waiver and PAR-Q+ come before the first physical assessment, not during it. Treat them as blocking items.
Photography client onboarding checklist
- Photography contract: deliverables, revisions, cancellation, weather clauses
- Deposit (often 25 to 50 percent, non-refundable)
- Copyright and usage terms
- Model releases for everyone you’ll use in your portfolio, minor releases for under-18s
- Property releases for private homes, businesses, or venues
- Client information form
- Shoot details: date, time, locations, parking, backup plan, number of people
- Shot list and must-have moments
- Venue rules on flash, drones, and restricted areas
Watch out: releases are much harder to collect after the shoot. Make them part of the booking, not the delivery.
Wedding planner client onboarding checklist
- Signed planning agreement with payment schedule and cancellation terms
- Retainer paid
- Couple questionnaire, filled in by each partner separately
- Wedding basics: date options, venue, guest count estimate, style
- Budget worksheet with who is contributing what
- Top priorities and deal-breakers
- Vendor release forms so you can contact and negotiate on their behalf
- Photo and social media release
- Inspiration boards and any vendor contracts already signed
- Draft guest list and VIP list
- Day-of decision-makers and emergency contacts
Watch out: when parents contribute, get the budget split in writing. It decides who approves what later.
How to run a client onboarding checklist without chasing
A checklist in a Google Doc still leaves you sending reminder emails and digging files out of attachments. Four habits fix most of it:
- One link, one place. Send the client a single portal link where they see every item, upload files, and sign. No “reply with attachments.”
- Batch the asks. Group items into steps (contract and payment, then information, then access) instead of a wall of 30 requests.
- Explain why. One line per item on what you’ll do with it. Clients send things faster when they understand the reason.
- Automate the follow-up. Reminders at day 3, 7, and 14 for missing items, sent by the system rather than by you. Here’s a guide to automated document reminders.
Superdocu is built for this. You turn any checklist above into a step-by-step workflow, and clients complete it in a portal branded with your logo and domain, logging in with a magic link instead of a password. You review and approve each document, reminders go out on their own, and renewable documents like IDs and insurance certificates get tracked for expiration. You can compare plans on the pricing page.
Frequently asked questions
What should be included in a client onboarding checklist?
At minimum: a signed agreement, the first payment, legal and billing details, a named decision-maker, an intake questionnaire, the documents and data you need to do the work, access to the client’s systems, and a communication plan. Your industry determines the specific documents.
How long should client onboarding take?
For most service businesses, one to two weeks from signed contract to kickoff. Accounting, insurance, and architecture take longer because third parties issue some documents, like IRS transcripts, loss runs, or surveys. Request those on day one.
What is the difference between client intake and client onboarding?
Intake happens before the client signs. It’s the questions you ask to qualify them and scope the work. Onboarding starts after signing and covers everything needed to begin: contracts, payment, documents, and access.
How do I get clients to send onboarding documents on time?
Send one link instead of a long email, split the requests into short steps, explain why you need each item, and automate reminders for anything missing. Setting a start date that depends on the documents also helps.
