Start by defining the relationship
People use the word “partner” for many arrangements: two freelancers delivering a project together, businesses referring customers to each other, or co-owners building a company. Before writing terms, describe what you intend to do together. Name the people or businesses involved, the purpose of the collaboration, the services or products in scope, and any important limits. If you are testing an idea for one project, say so rather than leaving the arrangement open-ended.
Identify what each party is contributing. Contributions might include time, equipment, access to customers, existing materials, or money. Be specific enough to avoid assumptions: “introduce potential customers” is different from “manage sales conversations and prepare proposals.” Note when the work begins, whether there is an expected end date, and whether either party may continue to serve other clients. These details give you a shared starting point for later decisions.
Assign responsibilities and decision-making
A useful agreement explains who owns each recurring task. For a joint client project, that might include proposals, delivery, scheduling, customer communication, invoices, and recordkeeping. For an ongoing venture, it might include product development, operations, and supplier relationships. Name a lead for each area, even if both people will contribute. Otherwise, routine work can be overlooked because each person expects the other to handle it.
Then decide how choices will be made. Which decisions can one person make independently, and which require agreement from everyone? Set a process for approving significant spending, changing prices, taking on new commitments, or changing the scope of work. You can also choose a regular time to review progress and record decisions. A simple written decision log helps when memories differ months later.
Include a way to handle a deadlock. For example, the parties might pause a proposed expense until they agree, while allowing previously approved work to continue. The aim is not to predict every disagreement; it is to prevent an unresolved question from quietly becoming a commitment.
Make the money understandable
State how income and costs will be handled. If customers pay for joint work, specify who invoices them, who receives payment, and when the other party is paid. Explain whether shares are based on revenue, profit, hours worked, or another measure. Terms such as “split the profits equally” need a definition of which costs are deducted first.
List the kinds of expenses that may be reimbursed and whether they need advance approval. Address what happens if a customer pays late, disputes an invoice, or asks for a refund. If one party contributes funds or pays a shared expense upfront, record whether that amount is a contribution, a reimbursable cost, or something else the parties have agreed to.
Choose a straightforward method for keeping records that both parties can inspect. Even a small collaboration benefits from consistent invoice references, saved receipts, and periodic reconciliations. Clear records do not eliminate difficult conversations, but they give those conversations a common set of facts.
Clarify customers, information, and work product
Discuss how the partnership will communicate with customers and what happens to those relationships afterward. If one party brings an existing customer, note whether that customer remains theirs outside the shared work. Agree on who may make promises to customers, use the other party’s name or logo, and describe the collaboration publicly.
Separate materials that existed before the partnership from materials created during it. The agreement can identify who may use templates, designs, software, customer lists, and finished deliverables, and for what purposes. It should also address access to shared files and accounts, including how access will be removed when the work ends.
If the parties will exchange confidential business or customer information, set expectations for who can access it, how it may be used, and when it should be returned or deleted. These questions are especially worth discussing before either party shares sensitive files.
Plan for changes and an orderly exit
Partnerships change as workloads, priorities, and customer needs change. Describe how the parties can revise the arrangement and how changes will be recorded. Set out how someone can leave, how much notice they should give, and what happens to unfinished work, outstanding payments, shared expenses, and customer communication. An exit process protects continuity even when the relationship ends on good terms.
Include a practical first step for resolving disagreements, such as a meeting where each party sets out the issue and a proposed solution. Also decide what records will be reviewed and who will tell customers if delivery is affected. Before signing, read the agreement together and test it against a few realistic scenarios: a delayed payment, an unexpected expense, or a partner becoming unavailable.
This is a planning checklist, not legal advice or a substitute for an agreement suited to your circumstances. The rules and consequences of a business partnership can vary by location and structure. If ownership, substantial money, sensitive information, or long-term commitments are involved, consider having a qualified professional review the arrangement.
