Going Into Business With Another Trainer: What to Settle First

Two trainers should go into business together only after writing down five things: who owns each client, how money moves and is split, who does what, who holds the booking and payment accounts, and exactly how either person leaves. Most partnerships between trainers do not fail on training philosophy; they fail on the unwritten answers to those five questions. One low-risk way to learn how you work together is two separate businesses in one facility, with your first hour free, before any legal merger.

What the rule says

This section is general information, not legal or tax advice, and rules change. On the points that matter most here, Indiana’s rules, as summarized in our September 2026 review, look like this: Indiana enforces a non-compete only when it is reasonable in time, geography and scope, and courts strike unreasonable terms instead of rewriting them. The same standard applies to independent contractors. An Indiana LLC’s articles cost under $100 to file online, and the Business Entity Report is due every two years in the anniversary month, at about $30 online. Beyond those points, have an attorney review anything you sign, because how two people who share profits are treated can turn on facts, not on what you call yourselves.

Start with ownership of the clients

The single most expensive misunderstanding is “whose client is this?” Pick a rule before the first shared client exists.

• Each keeps their own: simplest, best for two independent coaches who refer to each other.
• The business owns all clients: best when one brand name is sold, and both partners are paid from one shared account.
• Split by source: clients stay with whoever brought them in, and joint marketing produces shared clients that need a stated tiebreak.

Whichever rule you choose, write what happens to a client when a partner leaves. If the answer is “the client decides,” say so, and say that neither of you may contact them to push the decision.

Money: split the revenue, not the vague feeling

Agree on how a session fee travels from the client to your pockets. Revenue can be split by percentage, by hours delivered, or by a flat fee for the room plus a share for admin. Then list the costs that come off the top: space rental, insurance, software, marketing and equipment. Owner-to-associate arrangements and peer partnerships ask the same questions: who brings the client, who supplies the room, and who handles the admin.

Settle the unglamorous parts too: who pays for a no-show, who covers a refund, how taxes are handled on each partner’s share, and what happens in a slow month. Put sample numbers into the agreement, such as ten sessions at an example rate, so the formula is clear.

Roles, hours and the work nobody wants

Write down who handles scheduling, billing, social media, program design, equipment, cleanup and client complaints. Partnerships sour when one person quietly becomes the admin department. A rough weekly hours estimate for each task prevents the later resentment that comes from unpaid administration.

Add a decision rule too: which choices need both of you (a price change, a new hire, a new location) and which either may make alone.

Who holds the accounts

The booking account, the payment processor, the domain, the social handles, the email list and the business bank account should each have a named owner and a second authorized person. Whoever holds an account holds leverage, so agree on shared access from day one. If you rent space through an app, decide whether each partner books under their own name or a shared one, because the booking history is a record of who used what. Two trainers sharing a FlexSpace explains why hourly booking lets each partner keep their own account and still work in the same building.

Insurance, scope and the contract with clients

Each trainer should carry their own liability coverage, and the partnership should ask the insurer whether a joint business name or a shared client changes anything. Clients should sign a waiver and agreement naming the entity or trainer providing the service, which the LLC checklist for Indiana trainers explains as part of setting up the business.

The exit clause is the whole agreement

A good exit clause answers: how a partner gives notice, how the business is valued or simply wound down, how shared equipment is divided, what happens to the client list, and how long each partner’s non-compete or non-solicit lasts, if you use one. Keep any restriction narrow in time, area and scope, since an overbroad term may be struck rather than rewritten. Add a mediation step before any lawsuit, and review the agreement every year.

Test the working relationship, not just the math

Before signing anything, run two small experiments. First, co-coach one client or one small group for a month and debrief afterward on communication, timing and how each of you handles pushback. Second, handle a hypothetical crisis on paper: a client injury, a partner who is sick for two weeks, a bad review, a partner who wants to take a second job. How you each answer those scenarios predicts more about the partnership than shared enthusiasm does.

Pay attention to pace as well. One partner who wants to add a second location in a year and another who wants to stay small and local are not compatible, however friendly they are. Write down each partner’s two year goal and compare them honestly.

Finally, write a short communication rule: a weekly meeting at a fixed time, a shared document for decisions, and a promise to raise a concern within a week of noticing it rather than letting it grow quietly.

A sensible way to start

1. Spend three months as two businesses that share a space, a referral rule and a calendar.
2. Track real numbers: who brought which client, where hours went, how each of you handled problems.
3. Write the five answers above in plain English.
4. Have an attorney draft or review the final agreement.
5. Only then decide whether to form a shared entity, and use the first 90 days plan for independent trainers as a template for the opening quarter.

At FlexWerk in Carmel, trainers book hourly with no lease or membership and keep 100 percent of what they charge, so the trial phase costs only the hours you use. If the trial goes well, you will already have the data your agreement needs.
