How to Borrow Money From Business Partners

How to handle it

1. Check the operating agreement, shareholder agreement, or board approval requirements.
2. Write the business purpose and repayment source in plain language.
3. Set principal, interest, maturity, payment dates, collateral, and default terms.
4. Record approval, transfer funds to the business account, and track every payment.

Why this form of funding can work

A documented partner loan can add capital without immediately changing ownership, voting rights, or the economics of a future equity round. It also forces the leadership team to agree on the use of proceeds, repayment source, and lender priority before a cash shortage becomes a governance dispute.

Credit and management focus

Treat the partner as a real creditor: test debt service against operating cash flow, disclose existing obligations, and document whether the loan is secured, subordinated, or junior to bank, tax, payroll, and trade claims.

Common mistakes to avoid

• Calling a contribution a loan without a real repayment obligation.
• Giving one partner hidden priority over other owners or existing lenders.
• Changing terms informally instead of signing an amendment.

What to track after funding

Use one current ledger for the agreement and update it whenever money moves. The record should make it clear which payment cycle is due, what interest has accrued, and how much of each payment reduces principal.

• Payment cycle: next due date, payment frequency, grace or cure period, and whether the cycle is interest-only, amortizing, or tied to a specific collection or milestone.
• Principal: original amount advanced, principal repaid in each payment, remaining principal, and any approved additional draw, prepayment, or write-off.
• Interest: rate, calculation method, accrual period, interest due, interest paid, and any unpaid interest carried forward under the agreement.
• Payment allocation: show separately how each payment was applied to fees if lawful, accrued interest, and principal. Do not present a payment as principal reduction when it only covered interest.
• Performance and exceptions: repayment-source progress, covenant or milestone status, missed or late payments, notices issued, waivers, and signed amendments.

Documentation to supply

Keep an organized document pack that a lender, accountant, lawyer, auditor, or future funder can review without reconstructing the transaction from messages.

• Executed promissory note and any guarantee, security, subordination, or collateral documents.
• Borrower authorization, such as board, manager, shareholder, or partner approval where required.
• Evidence of the original disbursement, including payment confirmation and the receiving account.
• Repayment schedule and a current ledger showing the opening balance, interest, principal allocation, and closing balance for every cycle.
• Evidence supporting the repayment source, such as contracts, invoices, purchase orders, collection reports, operating cash forecasts, or asset information.
• Bank or payment-processor records that reconcile to the ledger, plus receipts or acknowledgements for each payment.
• Signed amendments, consent records, default or cure notices, and material communications when the original terms change.
