Bringing in a new business partner

Introduction

An owner is overloaded, or needs capital, or wants somebody to share the responsibility. A capable person is available and interested, and offering them a share of the business seems like the obvious way to secure them.

It is also the least reversible decision available. Selling or granting equity brings in a co-owner with rights, a claim on future profit and a say in decisions, permanently. There are frequently better ways to solve the underlying problem, and where a partner genuinely is the answer the terms matter more than the enthusiasm. Enthusiasm is what gets the deal done and the terms are what you live with.

1. Bringing in a new business partner is permanent in a way employment is not

Understand the asymmetry.

An employee who does not work out can leave. A part-owner has rights that continue, and removing them requires agreement or a mechanism you agreed in advance. This is why the decision deserves considerably more scrutiny than a hire.

2. Establish what problem you are actually solving

Diagnosis first.

Capacity, capital, skills, or somebody to share the burden. Each has alternatives — a senior employee, a loan, a contractor, a non-executive adviser — that solve it without giving away ownership.

3. Consider profit share or a bonus before equity

Frequently sufficient.

Somebody motivated by reward can be given a share of profits, a performance bonus or an option that vests over years. These deliver much of the incentive without the permanence of ownership.

4. Value the business properly first

Before agreeing any percentage.

Whatever the incoming partner is contributing has to be measured against what the business is already worth. Owners frequently give away a proportion of years of built value in exchange for something worth considerably less.

5. Decide what they are actually paying

Money, work, or both.

Buying in with capital is straightforward. Earning equity through future work needs a vesting arrangement with conditions, so that somebody leaving after a year does not retain a permanent stake.

6. Agree how decisions will now be made

Where the practical change is felt.

What requires the new partner's agreement, what does not, and what happens in a deadlock. An owner accustomed to deciding alone will find this the hardest adjustment, and it should be settled before completion rather than discovered afterwards.

7. Deal with existing debt and guarantees

Frequently overlooked.

Loans, overdrafts and personal guarantees given by the original owner do not automatically transfer. Agreeing whether the new partner shares that exposure is part of the negotiation, not an afterthought.

8. Put an exit mechanism in from the start

Before you need it.

How a share is valued, who may buy it, over what period, and what happens on death or departure. The moment to agree this is while both parties are optimistic and neither knows who will want to leave.

9. Take advice and document it properly

Not a handshake.

A shareholders or partnership agreement, share transfer documents and any tax consequences addressed. Both parties should have their own advice, which sounds adversarial and is what makes the arrangement durable.

Work with them for a period first if you can. A consultancy arrangement, a project, or a period as an employee reveals how somebody actually operates under pressure, and it is far easier to conclude at the end of six months that this is not the right partnership than to unwind ownership afterwards.

Conclusion

Recognise that this is permanent in a way that hiring is not.

Establish precisely what problem you are solving and whether an alternative addresses it, consider profit share or vesting options before granting equity, value the business before agreeing any percentage, decide whether they are contributing capital or future work and structure it accordingly, agree how decisions will now be made including deadlock, address existing debt and personal guarantees, include an exit mechanism from the outset, document it properly with separate advice on both sides, and work together for a period first.
