The Professional Services Cash Flow Challenge

Professional services firms face a persistent cash flow challenge: you complete work and bill clients, but payment arrives 30-90 days later. Meanwhile, payroll runs every two weeks. A business line of credit bridges this timing gap.

The flexibility to draw funds when needed and repay when payments arrive matches the variable nature of professional services cash flow.

How Firms Use Lines of Credit

  • Payroll coverage: Ensure payroll runs regardless of client payment timing
  • Receivables gap: Bridge time between billing and collection
  • Project ramp-up: Fund project costs before client payments begin
  • Business development: Marketing and client acquisition
  • Seasonal smoothing: Cover slow periods in cyclical businesses
  • Opportunity capture: Move fast on partnership or acquisition opportunities

Managing the Receivables Cycle

Professional services run on receivables. You bill for completed work, then wait for payment. A $100,000/month firm with 60-day average collection has $200,000 in receivables at any time.

A line of credit lets you operate normally while receivables mature. Draw to cover expenses, repay as clients pay.

Calculate your average collection period and multiply by monthly expenses. If you spend $80,000/month and collect in 45 days, you need access to approximately $120,000 in working capital.

Payroll Protection

Payroll can't wait for client payments. Missing payroll damages employee trust and may violate labor laws. A line of credit ensures payroll runs regardless of collection timing.

Think of your line of credit as payroll insurance—you hope you don't need it, but it's invaluable when you do.

Project-Based Cash Flow

Large projects create cash flow swings. You staff up, incur costs, and invoice milestones—but cash outflows often precede inflows.

A line of credit smooths these project cycles. Draw for project ramp-up, repay as milestone payments arrive.

Qualification Requirements

Line of credit qualification for professional services typically requires 1-2 years in business, consistent revenue (even if growing), personal credit score of 650+, healthy receivables (for AR-based lines), and debt service capability.

Strong billing and collection practices improve both approval chances and credit limits.

Building Credit Availability

Start with whatever line you can qualify for and build from there. Use it appropriately—drawing for legitimate working capital needs and repaying promptly.

Responsible use leads to limit increases. Many firms grow from $50K initial lines to $200K+ over several years.

Even if you don't need the full line now, having capacity available enables you to act on opportunities. Don't wait until you desperately need working capital to establish credit.

Costs and Structure

Line of credit costs include interest on outstanding balance (only what you've drawn), annual or monthly fees (some lenders), draw fees (less common), and early termination fees (review contracts carefully).

Compare total cost, including fees, when evaluating options.
