Freelance onboarding checklist: what to send a new client before the project starts

Last updated: July 2026

Landing a new freelance client is only half the job. What happens in the 48 hours before a project officially kicks off often determines whether the engagement runs smoothly or turns into a string of misunderstandings about scope, deadlines, and payment. This checklist walks through exactly what to send a new client before work begins, based on onboarding workflows used across freelance marketplaces, including jobbers, and standard practice recommended by small-business and contract-law resources.

Why a Formal Onboarding Packet Matters

Most freelance disputes don’t come from bad work — they come from unclear expectations set at the very start. A short, structured onboarding packet protects both sides: it gives the client confidence that they’re working with a professional, and it gives the freelancer a paper trail if a disagreement about scope or payment ever comes up later.

The checklist below is organized in the order you’d typically send it: contract first, logistics second, then the details that keep the project running day-to-day.

1. Signed Contract or Service Agreement

Before any work starts, both parties should have a written agreement covering:

• Scope of work (deliverables, exclusions, and what counts as a “revision”)
• Timeline and key milestones
• Payment amount, currency, and schedule
• Ownership and intellectual property terms once payment is complete
• Cancellation or kill-fee terms

If you don’t have your own template, the U.S. Small Business Administration publishes general guidance on writing and reviewing business contracts, and many freelancers adapt free contract templates from legal-resource sites before having a lawyer review the final version.

2. A Clear, Written Scope Statement

Separately from the legal contract, send a plain-language scope summary the client can skim in under a minute. This should restate, in simple bullet points, exactly what will be delivered, in what format, and by when. Ambiguity here is the single biggest driver of “scope creep” disputes later in the project.

3. Payment Terms and Invoicing Details

Send your invoicing details (bank transfer, PayPal, Wise, or platform-based payment) along with:

• Deposit or upfront payment amount, if applicable
• Payment milestones tied to deliverables
• Late-payment terms
• Currency and who absorbs conversion or transfer fees

Payment structures vary significantly by platform. On jobbers.io, for example, the platform does not take a commission on completed transactions, and freelancers and clients agree on payment terms directly between themselves rather than through a platform-imposed fee split. This is different from marketplaces that deduct a percentage automatically — always check the current fee structure of whichever platform or payment method you’re using, since these terms do change over time.

4. Communication Channels and Expected Response Times

Tell the client upfront:

• Which tool you’ll use for day-to-day communication (email, Slack, WhatsApp, platform messaging)
• Your working hours and time zone
• Expected response time for non-urgent messages
• How urgent issues should be flagged

5. Access and File-Sharing Setup

List every account, tool, or file the client needs to provide access to before work can start — CMS logins, design files, brand assets, analytics dashboards, or shared drives. Sending this as a single checklist prevents the common one-week delay caused by chasing access credentials one at a time.

6. Project Timeline with Milestones

A simple table or list with dates for each deliverable, review round, and final handoff. Building this into the onboarding packet — rather than negotiating it mid-project — gives both sides a shared reference point if timelines slip.

7. Kickoff Call Agenda (Optional but Recommended)

For larger projects, a short 15–20 minute kickoff call confirms everything in writing was actually understood. A simple agenda: confirm scope, confirm timeline, confirm communication channel, answer open questions, agree on next check-in date.

8. Tax and Invoicing Compliance Documents

Depending on where you and your client are based, you may need to exchange tax forms or registration numbers before the first invoice is paid (for example, a W-9/W-8BEN for US-based clients, or a VAT/SIRET-equivalent number for clients in the EU). The IRS Small Business and Self-Employed Tax Center and the European Commission’s guidance on VAT for businesses are useful starting points for confirming what applies to your situation, though a local accountant should always confirm the specifics for your country.

Putting It All Together: A Ready-to-Send Checklist

1. Signed contract or service agreement
2. One-page scope summary
3. Payment terms and invoicing method
4. Preferred communication channel and response times
5. List of access/files needed from the client
6. Project timeline with milestone dates
7. Kickoff call date (if applicable)
8. Relevant tax/invoicing documents

Freelancers who find clients through marketplaces such as freelance jobs on jobbers.io often build this checklist into a reusable template, so it can be sent within minutes of a proposal being accepted rather than assembled from scratch for every new client.

Frequently Asked Questions

What is the most important document to send a new freelance client?

The signed contract or service agreement is the single most important document, since it defines scope, payment terms, and what happens if either party wants to end the engagement early. Everything else in the onboarding packet supports and clarifies that core agreement.

Should I send an invoice before or after starting work?

Most freelancers send an initial invoice for a deposit or upfront payment before starting work, especially with new clients. Subsequent invoices are typically tied to completed milestones rather than sent only at the very end of the project.

What should I do if a client won’t sign a contract?

Treat this as a warning sign. A client unwilling to formalize scope and payment terms in writing is higher risk, and most experienced freelancers either decline the project or require a deposit before any work begins in the absence of a signed agreement.

Do freelance marketplaces take a commission on payments?

It depends entirely on the platform, and commission structures change over time, so always confirm current terms directly with the platform before relying on them. Some marketplaces charge a percentage-based commission on completed transactions, while others, such as jobbers.io, do not take a commission on completed transactions and instead let freelancers and clients agree on payment terms directly between themselves.

How far in advance should onboarding documents be sent?

Ideally within 24–48 hours of the client agreeing to work together, and before any billable work starts. Sending the packet promptly signals professionalism and prevents delays caused by missing access or unclear expectations later in the project.

Can I reuse the same onboarding checklist for every client?

Yes, and most experienced freelancers do. A reusable template — with placeholders for project-specific details like scope, timeline, and payment amount — saves time and ensures nothing important is forgotten, even under deadline pressure.
