Going into business with a partner: the money agreement

Business partnerships fail at rates that rival marriages, and the autopsy is almost always the same: money questions that were obvious to ask and awkward to raise, left unanswered until a dispute answered them expensively. The partnership agreement isn't paperwork for pessimists. It's the cheapest insurance in business — a few uncomfortable conversations, held while everyone still likes each other, that replace the six-figure lawsuit held after they don't.

The split is about the future, not the past

Fifty-fifty feels fair and is chosen by default — sometimes correctly, often because nobody wanted the conversation. Ownership should track what each partner will contribute going forward: capital, full-time labor versus nights-and-weekends, the client list, the technical skill that can't be hired easily. A partner investing $50,000 while the other invests sweat isn't a 50/50 story by default — it might be 60/40, or 50/50 with the capital treated as a loan the business repays first. There's no formula; there is a requirement that you reason it out loud and write down why.

The questions the agreement must answer

• Money in: who contributes what capital, and are contributions equity or loans? What happens when the business needs more cash and one partner can't add their share?
• Money out: salaries or draws — how much, on what schedule, and how are they set? How are profits beyond that split and when are they distributed (including enough to cover each partner's taxes)?
• Decisions: what needs both signatures (spending over $X, hiring, debt, contracts over $Y) versus what each partner decides alone?
• Exits: how is a departing partner's share valued (a formula — e.g., a multiple of revenue or earnings — beats 'we'll get an appraisal'), and on what payment terms (installments over 3–5 years, so a buyout doesn't kill the company)?
• The four D's: death, disability, divorce, and default — who can end up owning your partner's share, and does the company get first right to buy it back?
• Deadlock: with 50/50 owners, what breaks a tie? Mediation, a trusted third vote, or a buy-sell mechanism — anything but nothing.

Putting it in place

1. Draft answers to every question above with your partner first, in plain English — the arguing is the valuable part, and it's free.
2. Hire one attorney to turn it into an operating agreement (LLC) or partnership/shareholder agreement — typically $1,500–3,500. Templates are a starting checklist, not a finish line, because state law fills every gap you leave with defaults you didn't choose.
3. Add buy-sell funding for the death scenario: term life policies on each partner, owned so the survivor can actually afford the buyout the agreement promises.
4. Keep salaries, draws, and capital contributions documented as they happen — the agreement governs; the records prove.
5. Reread it every year or two: splits, salaries, and formulas that fit the $80,000 version of the business may misfit the $800,000 one.

The bottom line

Split ownership on future contribution and vest it. Write down how money enters, how it leaves, who decides what, and — above all — how a partner exits, at what formula, on what terms, in all four D scenarios. Pay an attorney a few thousand to make it real, and fund the death-buyout with term life. Every one of these clauses is awkward for an afternoon and priceless for a decade. The handshake is the beginning of the partnership; the agreement is what lets it survive being tested.

The five money questions to answer in writing

1. 1
   Ownership and vesting

   Who owns what percentage, and does it vest over time? Four-year vesting with a one-year cliff protects everyone from the cofounder who leaves in month five with half the company.

2. 2
   Pay before profit

   Who draws what salary, starting when, and what happens to pay in a cash crunch? Mismatched financial runways sink more partnerships than mismatched skills.

3. 3
   Money in, money out

   How are capital contributions treated — as loans, as equity, or as gifts to the venture? And what profit split and distribution schedule applies once there is profit to split?

4. 4
   Decision rights and deadlock

   What spending requires both signatures? Who breaks a 50/50 tie — a trusted advisor, a coin flip clause, a buyout trigger? Deadlock with no mechanism is how companies die mid-argument.

5. 5
   The exits

   Buy-sell terms for departure, disability, divorce, and death: valuation formula, payment schedule, and right of first refusal. Agreeing while you like each other costs $1,500 in legal fees; agreeing during a falling-out costs ten times that.

The pattern behind all five questions is the same: every clause is cheap to write while the answer is hypothetical and brutally expensive once it is not. Partners who cannot get through this list in a few honest working sessions have learned something important before it cost them the company — and partners who can will almost never need the document, precisely because writing it forced the conversations that prevent the disputes. Spend the $1,500 on a lawyer to formalize what you agreed; the alternative is spending $30,000 later to have a court decide what you never did.

And revisit the document at every structural change — a funding round, a first employee, a spouse joining the business, a partner's circumstances shifting. A partnership agreement is less a contract than a snapshot of what fairness looked like on the day you signed; the businesses that stay fair keep taking new snapshots. An annual thirty-minute read-through with both partners present costs nothing and catches the drift between what the paper says and what the partnership has quietly become.
