Quick answer: A business line of credit (LOC) is a revolving financing tool that gives companies flexible access to funds up to a set limit. Unlike a lump-sum loan, you borrow only what you need, when you need it, and repay it on your own schedule.

What Is a Business Line of Credit?

Think of it as a safety net: always available for payroll, supplier invoices, seasonal expenses, or emergencies. Mehmi Financial Group offers business lines of credit designed for Canadian small and mid-sized businesses.

BDC distinguishes a revolving operating facility from a term loan when explaining cash-flow financing.

Match the repayment structure to when cash is expected to arrive. Confirm whether the facility revolves, how repayments work and which security and renewal conditions apply.

How Business Credit Lines Work

Here’s the step-by-step process:

  1. Approval & Credit Limit


    • The lender approves you for a maximum amount (e.g., $100,000).

    • The limit depends on credit score, revenue, and sometimes collateral.

  2. Draw Funds as Needed


    • You don’t pay anything until you borrow.

    • Funds can be drawn via transfer, cheque, or business card access.

  3. Pay Interest Only on What You Use


    • If you borrow $20,000 from a $100,000 limit, interest accrues only on the $20,000.

  4. Revolving Credit


    • As you repay, funds become available again — like a credit card.

    • If you repay the $20,000, your full $100,000 limit is open again.

  5. Ongoing Access


    • LOCs can be open-ended or renewable annually, depending on lender terms.

Secured vs. Unsecured Business Credit Lines

  • Secured LOC: Backed by assets like receivables, inventory, or equipment.


    • Lower rates, higher limits.

    • Risk: lender can seize collateral if you default.

  • Unsecured LOC: Based only on credit strength.


    • Faster to approve, no collateral required.

    • Higher interest rates and lower credit limits.

Mehmi provides both options, depending on whether you qualify for secured loans or need an unsecured loan.

When Businesses Use Lines of Credit

  • Seasonal cash flow gaps (e.g., retail off-seasons)

  • Covering payroll or supplier invoices during slow months

  • Emergency expenses (equipment repair, sudden bills)

  • Taking advantage of short-term opportunities like bulk discounts

Industries such as construction, transportation, and hospitality often rely on LOCs for flexibility.

Benefits of a Business Credit Line

  • Flexibility: Draw only what you need.

  • Cash Flow Stability: Smooths out revenue fluctuations.

  • Revolving Access: Repay and reuse, unlike a one-time loan.

  • Lower Cost vs. Credit Cards: Typically lower interest rates than business credit cards.

Disadvantages to Consider

  • Higher Rates vs. Long-Term Loans: Interest is often higher than equipment loans.

  • Variable Rates: Many LOCs track prime rate, which can rise.

  • Lower Limits: You may not qualify for very large amounts without collateral.

  • Potential Overuse: Easy access can encourage bad borrowing habits.

Case Study: Manufacturing Firm in Ontario

A small manufacturer with $2M annual revenue secured a $150,000 line of credit. They used it to:

  • Cover raw material purchases while waiting for client invoices to clear.

  • Smooth payroll during seasonal slowdowns.

  • Draw $90,000 at peak season, repaid in 3 months after client payments arrived.

By paying interest only on the funds used, they saved significantly compared to taking out a lump-sum term loan.

FAQ: Business Lines of Credit
