Client onboarding

Let's get started.

This page is for owners who have decided to appoint A3. It sets out what happens next, gives you the documents you will need, and collects the details we need to open your engagement.

What happens next
01

Complete the intake form

Company, ownership and transaction details, plus the Buyer Schedule. Takes about 15 minutes. It comes straight to a principal.

02

Receive your Engagement Letter

We prepare the Engagement Letter, Fee Schedule and Buyer Schedule from your answers and send them for electronic signature.

03

Identity checks

We send each seller a secure link to upload photo ID and proof of address. Nothing is uploaded through this page.

04

Data room and kick-off

Within five working days of signing you receive your data-room invitation and a kick-off call is booked.

Your documents

Three documents to read before we start.

Enter your name and email and the document opens straight away. Everything else in your pack — the Engagement Letter, Fee Schedule, Buyer Schedule and Standard Terms — is prepared by A3 and sent to you for signature after the form below.

01

Welcome and Next Steps

How the engagement runs, your team, and the first 30 days.

02

Information Request List

Everything we need to value the business and prepare it for market. Priority items flagged.

03

How We Charge

Retainer, success fee, ratchet and worked examples.

Intake form

Tell us about the business.

Answer what you can; leave anything you are unsure of and we will pick it up on the kick-off call. Your answers are seen only by A3 principals and held under our Privacy Notice.

Declarations

You will receive an acknowledgement from a principal within one working day, followed by your Engagement Letter for signature. Please do not send financial documents or ID through this form — we will send you a secure data-room link.

Anything unclear before you start?
