The client signed your contract yesterday. The deposit invoice is sent. The start date is in three days. Everything feels aligned.
Then the client goes quiet. No deposit. No reply to your kickoff email. No access to their brand files. The start date arrives and you are still waiting. A week later, they reappear asking why nothing has been delivered yet.
This happens because most UK freelancers do not have a client onboarding checklist. You go from signed yes to starting work with no process in between. No checklist to confirm the deposit has cleared, no kickoff meeting to align expectations, no intake questions to collect what you need before billable hours begin.
This guide gives you a copy-paste client onboarding checklist for UK freelancers (designers, developers, writers, consultants), broken into three phases: before kickoff, kickoff week, and first deliverable. It includes intake questions, kickoff meeting agenda, and email scripts for when clients go silent or push back.
Why client onboarding fails for UK freelancers
Most onboarding guides are written for agencies, accountants, or large consulting firms. You are a solo freelancer or small studio. You do not have an account manager, a 10-page onboarding playbook, or a client success team.
You need a simple checklist that gets you from signed contract to kickoff to first invoice without ghosting, scope creep, or unpaid discovery work.
Common onboarding failures:
✓ Client ghosting after signing. They sign the contract, then disappear. No deposit, no replies, no start date. You chase for two weeks before giving up.
✓ Deposit never arrives. The client says "I sent it" but the payment does not clear. You start work anyway. Two weeks later, you are chasing and they have stopped replying.
✓ Scope drift before kickoff. The client emails: "Quick question before we start — can you also redesign the homepage? It is only a few extra hours." Now you are doing unpaid discovery before the project begins.
✓ Missing access or assets. You start work, then realise you need brand guidelines, hosting access, or a PO number. The client takes a week to send them. Your timeline is already blown.
✓ No kickoff meeting. You skip the kickoff because "the brief is clear." Three weeks later, the client rejects the first draft because "this is not what I meant."
The pattern: You treat onboarding as admin overhead instead of a gate that protects your time. No gate means clients drift in unprepared, and you invest hours before money or clarity arrives.
The master UK freelancer client onboarding checklist
This checklist has three phases. Do not skip to phase 2 until phase 1 is complete. Do not start billable work until phase 3 is complete.
Phase 1 — Before kickoff (signed contract to deposit received)
✓ Contract signed. Signed contract or SOW received via email or e-signature platform. Save a copy in your project folder and CRM.
✓ Deposit invoice sent. Deposit invoice sent to billing contact within 24 hours of signed contract. State clearly: "Work will commence once this deposit is received."
✓ Deposit paid and cleared. Check your bank account to confirm the deposit has arrived. Do not rely on "I sent it this morning."
✓ Billing details confirmed. Billing contact name, email, and PO number (if required) collected and logged in your CRM or invoice system.
✓ Project folder created. Client folder created in your file system (e.g. Google Drive, Dropbox, or local project folder). Subfolders for deliverables, assets, and invoices.
✓ CRM contact added. Client contact added to your CRM or contact list with project name, start date, and key stakeholders.
✓ Kickoff meeting scheduled. Kickoff meeting scheduled (after deposit clears) with calendar invite sent to all key stakeholders. Include meeting agenda in the invite.
Gate checkpoint: Do not schedule the kickoff meeting until the deposit has cleared. If the client chases you for a start date but the deposit has not arrived, reply: "Happy to schedule kickoff as soon as the deposit is received. Let me know when you have sent it and I will check my account."
Phase 2 — Kickoff week (first meeting to work start date)
✓ Kickoff meeting completed. 30–45 minute meeting to confirm goals, stakeholders, communication channels, response times, revision limits, and timeline. (See kickoff agenda below.)
✓ Communication channels confirmed. Agreed where updates will be sent (email, Slack, project management tool) and expected response times (e.g. 24–48 hours for feedback).
✓ Brand assets and access collected. Brand guidelines, logo files, hosting access, or any other assets required to start work received and saved in project folder.
✓ Revision limits reminded. Revision limits from contract (e.g. two rounds included, £X per additional round) restated during kickoff so client knows what to expect.
✓ First milestone date confirmed. First deliverable or check-in date agreed and added to your calendar and the client's calendar.
✓ Welcome email sent. Post-kickoff email summarising what was agreed, what happens next, and how to reach you. (See email script below.)
Gate checkpoint: If the client misses the kickoff meeting or does not reply to your access requests, do not start work. Send one follow-up email with a deadline: "I need [access / brand files] by [date] to start work on [start date]. If I have not received them by then, I will need to move your start date to the next available slot."
Phase 3 — First deliverable to first invoice
✓ First deliverable or check-in sent. First milestone delivered (e.g. wireframes, draft copy, first build) by agreed date.
✓ Client feedback collected. Feedback received and logged. If no feedback arrives within agreed timeframe (e.g. 48 hours), send reminder email.
✓ First invoice or milestone invoice sent. For milestone-based projects, send the first invoice after the first deliverable is approved. For retainer or time-based projects, send the first invoice at the end of the first billing period.
✓ Invoice payment tracked. Log invoice send date, due date, and payment received date in your CRM or accounting system.
✓ Post-first-milestone check-in. Quick email or message to confirm the client is happy with progress and the process so far. Fix any issues now before they become bigger problems.
Gate checkpoint: If the client does not pay the first invoice on time, pause work immediately. See our how to chase a late invoice guide for email scripts and your statutory rights under UK law.
Copy-paste client intake questionnaire
Send this questionnaire after the contract is signed but before the kickoff meeting. It collects everything you need to prepare for kickoff and start work without delays.
You can send this as a Google Form, Notion form, or plain email with the questions listed below. Adapt the questions to your discipline.
Subject: [Project name] — Client intake questionnaire
Hi [Client name],
Thank you for signing the contract. To prepare for our kickoff meeting and make sure I have everything I need to start work, please answer the questions below.
This should take 5–10 minutes. Reply by email or fill in this [form link] by [date].
Looking forward to working with you.
Best,
[Your name]
Client Intake Questionnaire
1. Project goals
What does success look like for this project? What is the main problem you are trying to solve?
2. Key stakeholders
Who are the key decision-makers and stakeholders involved in this project? Who will I be working with day-to-day, and who approves final deliverables?
3. Brand guidelines and assets
Do you have existing brand guidelines, logo files, fonts, or colour palettes? If yes, please share a link or attach them.
4. Preferred communication channels
Where would you like project updates and questions to go? (Email, Slack, Teams, phone, project management tool)
5. Response time expectations
What is your typical response time for feedback and approvals? (e.g. 24 hours, 48 hours, end of week)
6. Billing contact and PO details
Who should invoices be sent to? (Name, email, and postal address if required.) Do we need a purchase order (PO) number for invoicing? If yes, please provide it.
7. Access and credentials
What access will I need to start work? (e.g. hosting login, CMS access, Google Analytics, design files, GitHub repo) Please provide login details or invite me to the relevant accounts.
8. Revision and approval process
How will revisions and approvals work? Who reviews and approves deliverables before they go live or are considered final?
9. Timeline and constraints
Are there any hard deadlines, launch dates, or events this project needs to align with?
10. Questions or concerns
Is there anything else I should know before we start? Any concerns, preferences, or constraints I should be aware of?
Note: Adapt these questions to your discipline. A web developer needs hosting access and repo links. A brand designer needs existing logo files and competitors. A consultant needs stakeholder availability and internal data access.
Copy-paste kickoff meeting agenda (30–45 minutes)
Send this agenda 24 hours before the kickoff meeting as a calendar invite or email attachment. Covering these points upfront prevents confusion, scope creep, and misalignment later.

Five copy-paste onboarding email scripts
Script 1 — Sending the deposit invoice after contract signed
Subject: [Project name] — Deposit invoice and next steps
Hi [Client name],
Thank you for signing the contract. Attached is the deposit invoice (£[amount]) to secure your project start date.
Once the deposit is received, I will send the client intake questionnaire and schedule our kickoff meeting. Work will commence once we have completed kickoff and I have confirmed all access and assets are in place.
You can pay by bank transfer using the details on the invoice. Please let me know once you have sent payment, and I will confirm when it has cleared.
Looking forward to working with you.
Best,
[Your name]
Script 2 — Sending the kickoff invite after deposit clears
Subject: [Project name] — Kickoff meeting scheduled
Hi [Client name],
Great news — the deposit has cleared, and we are ready to start.
I have scheduled our kickoff meeting for [date and time]. Calendar invite is attached. The meeting will take 30–45 minutes and will cover project goals, timeline, communication, and what I need from you to start work.
I have also attached a short client intake questionnaire. Please complete it before the meeting (it takes 5–10 minutes) so I can prepare and make sure we cover everything during kickoff.
See you on [date].
Best,
[Your name]

If you have sent the payment, please let me know and I will check my account. If not, please send it by [deadline date] so we can keep to the agreed timeline.
If I do not receive the deposit by [deadline date], I will need to move your start date to the next available slot, which is [new date].
Let me know if you have any questions.
Best,
[Your name]
Script 5 — When client wants to skip kickoff
Subject: Re: Kickoff meeting — [Project name]
Hi [Client name],
I understand you are short on time, but the kickoff meeting is important. It is only 30–45 minutes and will save us both time later by making sure we are aligned on scope, timeline, and communication before work begins.
Skipping kickoff usually leads to misalignment, rework, or scope creep — all of which cost more time than the meeting itself.
If you really cannot make the meeting, I can send the kickoff agenda by email and ask you to confirm you have read it and agree with everything before I start work. But a live meeting is always better.
Let me know what works for you.
Best,
[Your name]
What to collect before you start billable work
Do not start billable work until you have collected all of these. Missing one means delays, rework, or unpaid hours.
✓ Signed contract or SOW. No signature, no work. Verbal agreements are not contracts.
✓ Deposit invoice paid and cleared. Check your bank account. "I sent it" is not the same as "It has cleared."
✓ Billing contact details. Name, email, postal address (if required), and PO number (if required). If you invoice the wrong contact, payment will be delayed.
✓ Brand assets and access. Logo files, brand guidelines, hosting login, CMS access, GitHub repo, or any other access required to start work.
✓ Kickoff meeting completed. 30–45 minute meeting to align on goals, timeline, communication, and revision process.
✓ First milestone date confirmed. You and the client both have the first deliverable date in your calendars.
Rule: If a client chases you to start work before these are complete, reply: "I am ready to start as soon as [missing item] is confirmed. Let me know when you have sent it and I will get started immediately."
Do not let client urgency pressure you into starting work before you have been paid and prepared.
How to onboard clients when they are slow to respond
Some clients sign the contract, then go silent. They do not reply to your deposit invoice, your intake questionnaire, or your kickoff invite. You chase. They reply a week later: "Sorry, been busy. When can we start?"
What to do:
✓ Set deadlines. Every email you send should include a deadline. Example: "Please send the deposit by [date] so we can keep to the agreed start date."
✓ Explain consequences. State clearly what happens if the deadline is missed. Example: "If I have not received the deposit by [date], your start date will move to [new date]."
✓ Do not chase forever. Send two follow-ups maximum. If the client still does not reply, archive the project and move on. Clients who ghost during onboarding will ghost during the project.
✓ Offer an alternative. If the client is slow because of internal approval delays, offer milestone invoicing or a shorter deposit percentage. Example: "If 50% upfront is difficult, we can do 30% now and invoice the rest in two milestones."
Script for slow clients:
Hi [Client name],
I have not yet received [deposit / access / signed contract]. I have reserved your project start date for [date], but I need [missing item] by [deadline date] to keep to that timeline.
If I do not receive [missing item] by [deadline date], your start date will move to the next available slot, which is [new date].
Please let me know if there is anything blocking this on your side, and I will do my best to help.
Best,
[Your name]
If the client misses the deadline, do not chase again. Move their start date and take on other work. Clients who miss onboarding deadlines usually miss project deadlines too.
When to skip kickoff (and when you should never skip it)
Most projects benefit from a kickoff meeting. But not all.
You can skip kickoff when:
✓ The client is a repeat customer and you already know how they work
✓ The project is very small (under £500) and the brief is simple and clear
✓ You are working on a retainer and have a weekly or fortnightly check-in already scheduled
You should never skip kickoff when:
✓ The client is new and you have no payment history with them
✓ The project is over £1,000 or longer than two weeks
✓ The brief is vague or the scope is unclear
✓ There are multiple stakeholders and you do not know who approves deliverables
✓ The client has already changed the brief or added scope before work has started
Rule: If you are unsure whether kickoff is needed, do it. 30–45 minutes upfront prevents hours of rework and confusion later.
