Decide the split before you sell anything, not after — a 50/50 split works if you're contributing equally, but if one of you is doing noticeably more (materials, time, selling), a split that reflects that is fairer and avoids resentment later. Write it down, even informally, so there's no disagreement once real money shows up.
Starting a business with a friend is exciting right up until the first sale happens and neither of you is quite sure who gets what — which is exactly why this needs to be settled before that moment, not after.
Decide before the money shows up
The single biggest source of friction between friends running a business together is leaving the money split undecided until there's actual money to argue about. Have the conversation at the very start, even if it feels awkward or premature. "What happens with the money if we sell something?" is a much easier question to answer calmly before either of you has a stake in the answer.
Is 50/50 actually fair?
A straight 50/50 split makes sense when you're both genuinely putting in similar amounts of time, money, and effort. It stops making sense the moment one of you is doing noticeably more — buying most of the materials, doing most of the making, or handling all the customer conversations. In that case, a split that reflects the actual contribution (60/40, or whatever fits) tends to feel fairer to both people, even if it's not an even number.
How to figure out a fair split
Lay out, honestly, what each of you is actually contributing:
- Who's paying for materials or supplies?
- Who's doing the making or producing?
- Who's finding and talking to customers?
- Whose idea was it originally, if that matters to either of you?
There's no single formula — the point is having this conversation out loud, together, rather than one of you silently deciding what's fair and hoping the other agrees.
Write it down, even informally
You don't need a formal contract for a small first business. A shared note, a text message both of you reply "agreed" to, or even a photo of something scribbled on paper is enough — what matters is that the agreement exists somewhere outside memory. Memories of a verbal agreement tend to drift apart once real money and real effort are involved, especially if the business does better (or worse) than expected.
What if contributions change partway through?
It's normal for the balance of effort to shift as a project goes on — maybe one of you gets busier, or one of you ends up doing most of the selling. When this happens, bring it up directly and recalculate together, rather than letting resentment build quietly. A short, sometimes uncomfortable conversation now is far cheaper than a friendship-damaging blowup later.
Why this matters more than it seems
Money problems are one of the most common reasons friend-run businesses fall apart, not because the business itself failed, but because nobody had the plain conversation about who gets what before it mattered. Having that conversation early protects both the business and the friendship — which, for most teens starting out, matters a lot more than the money itself.
Key takeaways
- Agree on the split before the first sale, not after money arrives
- 50/50 only makes sense if contributions are genuinely equal
- Write the agreement down, even just in a shared note
- Revisit the split if contributions change significantly partway through
- A short, honest conversation now is cheaper than a conflict later
Frequently asked questions
Should we always split 50/50 with a friend?
Only if you're contributing roughly equally. If one person is doing clearly more, a split that reflects that is fairer.
What if we didn't agree on anything before we started selling?
Have the conversation now, as early as possible — it only gets harder the longer it's avoided.
Does the agreement need to be formal?
No — a shared note or text message both agree to is enough, as long as it's written down somewhere.
What if one of us contributes a lot more partway through?
It's fair to revisit the split. Bring it up directly rather than quietly resenting it.

Frequently asked questions
Should we always split 50/50 with a friend?
Only if you're contributing roughly equally — time, materials, money, and selling effort. If one person is doing clearly more, a split that reflects that (like 60/40) is fairer and reduces resentment later.
What if we didn't agree on anything before we started selling?
Have the conversation now, as early as possible. It's an uncomfortable conversation to have after money exists, but it only gets harder the longer it's avoided.
Does the agreement need to be formal?
No — a shared note or text message both of you agree to is enough for a small first business. What matters is that it's written down somewhere, not just remembered.
What if one of us contributes a lot more partway through?
It's fair to revisit the split if the balance of effort changes significantly. Bring it up directly rather than quietly resenting it — a short conversation fixes this faster than letting it build.
