Both working capital loans and business lines of credit provide your business with operating funds — but the mechanics are fundamentally different, and choosing the wrong product can cost you significantly more than necessary or leave you without access when you need it most.

This guide breaks down the structural difference clearly, gives you specific use-case guidance, and explains what Merchant Fund Express offers in each category.

Defining Working Capital and Line of Credit

Working capital loan: A term loan that provides a single lump sum of cash deposited to your business account. You repay it through fixed daily, weekly, or monthly payments over a defined period. Once you repay the full amount, the product is closed — to access more capital, you apply for a new advance.

Business line of credit: A revolving credit facility with a set credit limit. You draw funds as needed (up to the limit), repay them, and draw again. You only pay interest or fees on the amount drawn, not the full credit limit. The available balance replenishes as you repay.

Simple Analogy: A working capital loan is like a one-time withdrawal from an ATM — you get the cash, spend it, repay it. A line of credit is like a credit card with a high limit — draw, repay, draw again, pay only on what you use.

Lump Sum vs. Revolving: The Core Structural Difference

The lump sum vs. revolving structure determines almost everything else about these products — their best use cases, their cost structure, and their risk profile for the lender (which affects your rate).

Lump sum working capital is appropriate when you have a specific, known expense or investment you need to fund — a bulk inventory purchase, a piece of equipment, a marketing campaign, hiring and onboarding costs. You know what you need, you get it, you repay it.

Revolving credit is appropriate when your capital needs are ongoing, variable, and unpredictable — cash flow management between payroll cycles, seasonal inventory needs, bridging gaps between customer payments, handling unexpected expenses as they arise. You want access to capital without reapplying every time.

Best Use Cases for Each Product

When a Working Capital Loan Is Right

  • Large inventory purchase: You need $80,000 to buy seasonal inventory before your busy period — a defined need with a clear ROI
  • Equipment purchase: Smaller equipment needs that do not justify full equipment financing
  • Hiring and onboarding: Funding a growth sprint where you are adding 5 employees at once — known cost, known timeline
  • Specific project costs: A contractor who needs to fund materials for a large project that will pay in full at completion
  • Bridge financing: Covering a specific short-term gap while a larger financing event processes

When a Line of Credit Is Right

  • Cash flow smoothing: Managing the timing gap between when you pay expenses and when customers pay you
  • Payroll protection: Ensuring payroll is always covered during slow revenue periods
  • Opportunistic purchases: Having available credit to act on vendor discounts, opportunistic deals, or unexpected opportunities as they arise
  • Seasonal businesses: Drawing heavily in Q4, repaying through Q1–Q3
  • Emergency buffer: A line of credit you only draw when truly needed — the cost of maintaining it unused is zero or minimal

Cost Comparison

The cost structure of these products differs significantly depending on how you use them:

  • If you need the full amount for a defined period: A working capital loan with a known factor rate may be more cost-efficient because the total cost is fixed and transparent upfront
  • If you need partial, intermittent access: A line of credit is almost always cheaper because you only pay on drawn balances — a $100,000 line where you draw only $30,000 costs far less than a $100,000 working capital advance
  • If you pay revolving credit slowly: Lines of credit can become expensive if balances are carried for extended periods — the revolving structure incentivizes faster repayment

What Merchant Fund Express Offers

Merchant Fund Express provides both working capital loans and business lines of credit:

Working Capital Loans at MFE

  • Amounts: $10,000 to $500,000
  • Terms: Flexible daily/weekly repayment
  • Approval time: 24–48 hours
  • Minimum requirements: 6 months in business, $10,000/month revenue, 500+ credit score
  • No collateral required

Business Lines of Credit at MFE

  • Draw funds within 24 hours of approval

Which One Should You Apply For?

The decision is simpler than it seems:

  • If you have one specific need with a known dollar amount → Working Capital Loan
  • If you want ongoing access for variable needs → Business Line of Credit
  • If you are under 12 months in business → Working Capital Loan (lines of credit typically require longer history)
  • If you want the best long-term cost for recurring needs → Business Line of Credit

Many businesses benefit from having both — a working capital advance for a specific initiative and a line of credit as an ongoing cash flow buffer. Talk to an MFE advisor about structuring both products to work together.

Key Takeaways

  • Working capital loans deliver a lump sum; lines of credit revolve — you draw, repay, and draw again
  • LOCs cost less if you draw partial amounts and repay quickly; WC loans have fixed, predictable total cost
  • Use working capital loans for specific, one-time needs; use lines of credit for ongoing cash flow management
  • MFE offers working capital loans from $10K–$500K and lines of credit up to $250K
  • Both products are accessible with 500+ credit score and $10K+ monthly revenue
  • Lines of credit are better for businesses with 12+ months of history; working capital from month 6
  • Having both products simultaneously is a legitimate and effective strategy

Frequently Asked Questions

What is the difference between working capital and a line of credit?
A working capital loan provides a lump sum you repay over a set period. A line of credit is revolving — draw what you need, repay it, and draw again. WC loans suit one-time needs; LOCs suit ongoing, variable needs.
Which is cheaper — a working capital loan or a line of credit?
LOCs are typically cheaper if you draw only what you need and repay quickly. WC loans have fixed cost regardless of repayment speed. For a single large known expense, WC may be more cost-effective.
What credit score do I need for a business line of credit?
Merchant Fund Express offers business lines of credit for owners with credit scores as low as 500, with approval based primarily on monthly revenue and bank statement health.
Can I use a line of credit for working capital?
Yes. A business line of credit is one of the most flexible working capital tools — draw for payroll, inventory, or operating expenses, then repay and redraw.
How is a working capital loan different from an MCA?
Both provide lump-sum capital, but an MCA repayment adjusts based on daily revenue percentage. A working capital loan has fixed scheduled payments regardless of daily sales.
What is the maximum for a business line of credit at MFE?
Merchant Fund Express offers business lines of credit up to $250,000 based on business revenue and financial profile.
How fast can I access a business line of credit?
Once approved, draws can be made within 24–48 hours. Initial approval typically takes 1–3 business days.
