What happens on completion day

Owners spend months thinking about price, structure and the right buyer. Far fewer think about the day the deal actually completes. Yet completion is when ownership changes hands, the money moves and your role in the business shifts, often within a few hours. Knowing what to expect makes the day calmer, and a calm completion is usually a smoother one.

Every deal is different, and the mechanics vary between the UK and the US and from one transaction to the next. But the shape of the day is broadly similar. Here is how we walk owners through it.

Exchange, signing and completion

In the UK you will often hear about exchange and completion. Exchange is when the sale agreement is signed and both sides are legally committed. Completion is when ownership passes and the price is paid. In many SME deals the two happen on the same day. In others there is a gap, usually because something still has to happen first, such as a regulatory approval, a landlord's consent or a key customer agreeing to the change of control.

In the US the language is usually signing and closing, and the same idea applies. If there is a gap, the agreement will list the conditions that must be met before closing, and both sides work through them in the meantime. If everything can be done at once, the deal signs and closes together.

What you will be asked to sign

The main document is the sale agreement, but it rarely travels alone. Depending on the deal, the completion pack might include:

• The disclosure letter or disclosure schedules, setting out the exceptions to the warranties you are giving.
• Share transfer forms or assignment documents that move ownership to the buyer.
• Board minutes approving the transfer and any changes of directors or officers.
• Resignation letters from directors who are stepping down, and appointments for those joining.
• A service or consultancy agreement if you are staying on for a period after the sale.
• Any loan notes, earnout terms or other deferred payment documents agreed as part of the price.
• Releases of personal guarantees or security over business assets, where these have been negotiated.

Your lawyer will usually prepare a completion checklist that lists every document, who signs it and who holds it. It is worth asking for that list a week or two before the target date and reading it properly. It is the clearest single picture of what the day involves.

How the money moves

On completion, the buyer, or their lawyer, sends the funds due at completion. Where there is bank debt in the business, part of the money often goes straight to the lender to repay it, and the lender releases its security at the same time. Where there is a cash-free, debt-free price, the completion statement or estimate shows how the headline figure turns into the amount that actually reaches you.

Money moves between lawyers' accounts and banks, and same-day transfers can take a few hours. It is normal for the documents to be signed in the morning and the funds to arrive later in the day. Agree in advance what time the transfer is expected and who confirms receipt, so nobody spends the afternoon refreshing a banking app.

What changes in the business that day

Several practical things usually happen on or around completion. Bank mandates change so the new owner controls the accounts. Company records are updated with the new shareholders and directors. Insurance may move onto the buyer's policies. Passwords, keys and access to key systems are handed over or shared as agreed.

None of this should be a surprise. A good buyer will have agreed with you, before completion, exactly which items move on the day and which can wait. A short handover list, drawn up together, avoids the situation where a supplier calls on day two and nobody knows who can approve a payment.

Telling your people

For most owners the most important moment of completion day is not the signing. It is the conversation with the team. Whether you tell your managers before or after completion, and how you tell everyone else, should be planned with the buyer well ahead of time.

We find it helps to agree a simple plan: who speaks first, what is said, what happens to roles and terms, and who people can come to with questions. Your team will take their lead from you. If you are clear and settled about the decision, it gives them permission to feel the same. Customers and key suppliers usually follow shortly afterwards, again with a message agreed in advance.

How to make the day calm

A few simple habits make a real difference:

• Ask for the completion checklist early and go through it line by line with your lawyer.
• Sign what can be signed in advance, so the day itself is about release rather than paperwork.
• Keep the day free. Do not book client meetings or travel around it, because timings often move.
• Know who to call. Have direct numbers for your lawyer, your accountant and the buyer's lead contact.
• Plan something for the evening. Completion can feel strange, and marking it with family or friends helps.

Late surprises usually come from things that were known about but left until the end, such as a missing landlord consent or an unsigned customer contract. Clearing those in the weeks before completion is the single best way to protect the date.

After completion

Completion is not quite the end. There may be a completion accounts process in the months that follow, deferred payments to track, and a handover period where you help the new owner settle in. Some owners find the first few weeks the hardest part emotionally, because the routine they have had for years suddenly changes.

That is normal, and it is worth planning for. Agree how often you will speak with the new owner, what you are and are not responsible for, and when your involvement will step down. Clear expectations on both sides make it far easier to let go well.

How we approach completion

As a long-term buyer, we treat completion as the start of looking after the business, not the finish line of a transaction. We share a clear checklist early, agree the handover and the announcement plan with you, and aim to make the day itself straightforward so you can focus on your people.

If you are thinking about selling and would like a private conversation about what the process and completion might look like for a business like yours, a short call is a good place to start. There is no obligation either way.
