The Co-Founder Money Playbook: How to Share Expenses Without Ruining Your Partnership

No amount of reading or brainstorming can truly prepare you for the realities of building a business with a partner.

The initial excitement and thrill of the shared venture, pouring over coffee-stained documents and discussing late into the night, eventually wears off.

Reality sets in, and it’s a long, grueling slog. Money, inevitably, becomes a huge issue.

When you’re no longer just discussing ideas, and you begin to manage actual money, the dynamics of your relationship can shift very quickly.

Your personal money issues will become exposed very quickly, and even if you haven’t addressed them before, you’ll have to deal with them when managing joint business expenses.

If you haven’t already compared your financial mindsets with your co-founder, it would be very helpful to have this conversation.

Small misunderstandings about managing shared business expenses can quickly turn into large conflicts.

Managing business expenses effectively is not just about keeping good accounting records; it’s also about building a foundation of trust for your partnership.

The Real Cost of Unclear Financial Boundaries

In the early stages of the venture, when the business is just getting off the ground, you might find that money management gets put to one side as more important priorities take over, such as product development and acquiring customers.

You might use your personal credit cards for the occasional software subscription that comes up, or pool your personal funds to create a temporary ‘pot’ of money to use as needed.

You might promise to settle up with your partner at the end of the month for any venture expenses that you have each incurred.

After a few weeks of running your new business informally, the situation can quickly deteriorate as your business expands.

Another subtle pitfall is letting money issues cause resentment when they arise due to a lack of clear financial boundaries.

Does your partner feel they are carrying too much of the load for the initial start-up expenses?

You feel that they are being too controlling and that you can’t even make a legitimate purchase for the operation of the business without having to “check in” with your partner?

The worst thing is that usually these types of financial issues create tons of mental effort to negotiate every single expense and thereby suck the energy out of you that you could have otherwise put into your business to grow it.

That is to wear down any human.

Setting Up a Dedicated Financial Home

So, what is the first step in all of this toward becoming a healthier and more productive co-founder?

Set up a dedicated financial home for your company.

Keep business and personal money separate, and maintain a clear, transparent system for tracking and viewing all company-related expenses and revenue.

First, separate your finances from your partner’s.

Set up a joint business financial hub that you can both easily access. Having a centralized financial system will help you both understand where your business money is going.

In terms of banking, many founders look for the best banks for joint accounts that offer multi-user access, low fees, and digital tools to make managing money as easy as possible.

In addition to setting up the joint account, you and your co-founder will need to establish rules for using the account to manage your finances.

Decide who can approve certain expenses and who will be responsible for approving recurring payments, such as for software that your business uses.

Establish a system for handling unexpected expenses that require large sums.

In addition to setting up a joint account, it is also important to establish parameters around how the account will be used to manage joint finances.

This could include who is authorized to spend money above a certain threshold, how recurring software subscriptions will be paid for, and how you will cover unexpected expenses from time to time.

If you haven’t already, it is a good idea to write down your money parameters in a shared document and refer to it from time to time to stay on track.

Normalizing the Uncomfortable Money Conversations

Most financial conflicts in a business partnership between two people arise when one or both partners avoid discussing the financial management of their venture.

Most people do not like to talk about their personal finances, and in a close partnership of two founders, it is even more difficult.

But there is no way to avoid discussing the financial management of your venture, as the financial conflicts that arise will become much worse if you avoid them.

I was surprised by how long it took me to realize that avoiding an uncomfortable money conversation only results in a worse conflict later on.

Whether the venture is growing or in decline, the most successful partnerships hold regular financial check-ins, for example, every two weeks or a month.

These meetings are used to discuss cash burn, any liabilities due, and any investments needed to operate the business.

The money talks shouldn’t feel tense or difficult.

By incorporating money reviews into your standard meeting schedule, you can bring them to the table as you normally would to review and agree upon, rather than as unusual or contentious topics.

By working with money this way, the financial aspects of your business become just one more of the many issues for you to be concerned with to help your business succeed, rather than becoming the focus for you both as founders.

Designing a Decision Matrix for Spending

One way to enable fast growth in a partnership while keeping both founders accountable for all expenses is to establish a “spending tier” for decision-making.

The spending tier each expense falls under would dictate how it is approved. For example, the founders could agree to establish the following spending tiers:

Here is an example of a simple-to-use decision matrix for spending money as a co-founder.

Tier 1 - Under $200: Each founder can approve their own spending within a budget.

Tier 2 (Medium Impact): Expenses that fall between the amount for which one person can spend and the amount for which two people should spend together (2 hundred to 1 thousand dollars) require a quick heads-up or an async discussion to verify that spending this amount is within the partners’ jointly agreed budget.

Tier 3 (High Impact): Major expenses, long-term contracts, or strategic pivots that require a formal discussion and both partners’ approval.

This way, both partners can act quickly on day-to-day matters while jointly deciding on larger financial matters for the company.

Planning for the Unexpected

It’s inevitable: even with the best of partnerships, you will encounter financial stress at some point.

This can be the result of market changes or of your product launches not occurring as quickly as you had hoped.

It could be because of unforeseen expenses.

Whatever the reason, it’s how you deal with it that really matters.

The true test of any partnership isn’t how they handle making a profit; it’s how they cope when things go wrong, and the runway is shrinking.

Before you encounter cash flow problems, you should outline an emergency plan to handle them.

What are the actions you will have to take to ensure the continued existence of your company when the cash stops coming in?

Will you split additional personal funds equally?

Or will you cut back on expenses across the board?

Having an agreed plan in place will reduce the emotional stress experienced when a tight cash runway is encountered and reduce the potential for either partner to make financial decisions under pressure.

Building for the Long Haul

When setting up a business partnership, there are several factors to consider.

However, with clear systems, communication, and financial transparency, all can be overcome.

Setting up structures early on and agreeing on spending boundaries will help you manage your business finances and partnership.

When money matters are structured and transparent, you free up your mental bandwidth to focus on what brought you together in the first place, i.e., building something great together.
