The Web Agency Client Onboarding & Delivery Template

The difference between agencies that run smoothly and agencies that don't is rarely the quality of work. It's the process around the work. A structured client onboarding process sets expectations, prevents scope creep, and ensures every project ends with a clean, professional delivery.

Why most agencies skip this — and why it costs them

When you're busy, process feels like overhead. It's easier to just "get on with it" and deal with issues as they come. The problem is that issues compound. Without a defined onboarding process:

  • ✕Clients add features mid-project with no clarity on cost
  • ✕Sign-off never happens formally, creating payment disputes
  • ✕Delivery is chaotic — emails everywhere, nothing organised
  • ✕Clients don't know how to use their site and call you for months
  • ✕The final impression undermines months of good work

A repeatable 5-phase process eliminates all of these. And once it's built, it adds almost no time to your workflow — you're doing the same things, just in the right order, with the right documentation.

The 5-phase template

01

Kickoff

Day 1

The kickoff establishes expectations before a single pixel is designed. Done well, it prevents 90% of scope creep and communication problems.

  • Send a formal kickoff document (project scope, timeline, payment schedule)
  • Get written sign-off on the scope before starting
  • Introduce the client to your project management tool or portal
  • Agree on communication channels (email only, Slack, project messaging)
  • Establish revision policy in writing (e.g. 2 rounds included)
  • Collect all client assets upfront (logo, brand guidelines, copy, images)
  • Define what "done" looks like for each deliverable
02

Mid-Project Check-in

At agreed milestone (e.g. design approval)

A structured mid-project check-in prevents surprises at launch. Share progress formally, get written approval on the design direction, and flag any scope changes early.

  • Present designs or development progress in a structured format
  • Get written approval on design direction before building
  • Document any scope changes in writing with associated costs
  • Confirm the remaining timeline and upcoming milestones
  • Collect any remaining content or assets needed to complete the build
  • Remind the client of the revision policy if relevant
03

Pre-Launch Review

1–2 weeks before handoff

Before handing anything over, run a structured review to catch anything missed. This is also when you prepare all the handoff materials so delivery day is smooth.

  • Full cross-browser and device testing
  • SEO basics checked (titles, descriptions, sitemaps, alt text)
  • All third-party integrations tested end-to-end (forms, payments, email)
  • Gather all credentials into your handoff system
  • Prepare source files, exports, and documentation
  • Prepare training materials (video walkthroughs, written guides)
  • Draft the final invoice
  • Prepare the client portal or handoff package
04

Delivery

Project completion

This is the phase most agencies handle poorly. A professional delivery isn't a wall of emails — it's a structured, branded experience that leaves the client feeling looked after.

  • Send the client their portal link (or handoff package)
  • Credentials delivered securely — never emailed in plain text
  • All files organised into clearly labelled folders
  • Formal sign-off checklist for each deliverable
  • Training materials accessible and clearly organised
  • Final invoice sent (consider holding access until paid)
  • Handover call or walkthrough scheduled if included in scope
  • Define the support period and what's included
05

Post-Delivery

1–4 weeks after handoff

Most agencies disappear after delivery. A short post-delivery follow-up reduces support calls, generates reviews, and opens the door to future work.

  • Check-in message 1–2 weeks after handoff (is everything working?)
  • Request a Google or Trustpilot review while satisfaction is highest
  • Document lessons learned for your next project
  • Archive all project assets internally
  • Add the client to your newsletter or future outreach list if agreed

What tools to use

You don't need a complex tech stack. Most agencies run well with three tools:

Project management

Notion, Linear, Asana

Internal task tracking, briefs, and timelines.

Communication

Email, Slack

Day-to-day client communication during the project.

Client delivery

SmoothHandoff

Credentials, files, sign-offs, training, and invoicing at handoff.
