Landing a bigger client is supposed to feel like a win. New logo, bigger order size, real proof your business can play at a higher level. Then the contract shows up with net-60 payment terms, or worse, net-90, and the win starts to feel like a liability.

This catches founder led businesses off guard more often than it should. You didn't have this problem when your customers were smaller and paid on receipt or net-15. Growth changed your customer mix, and your cash flow plan didn't get the memo.

Why Bigger Customers Push for Longer Terms

Larger companies run their own AP processes on a schedule built for their convenience, not yours. Net-60 and net-90 are standard procurement terms at a lot of mid-market and enterprise buyers, and they aren't usually negotiable line by line, especially early in the relationship before you have leverage.

The math that makes this dangerous is simple: your costs to deliver the work (labor, materials, subcontractors) are still due on your normal schedule. Payroll runs every two weeks regardless of when your customer's AP department decides to cut a check. You end up financing your customer's working capital with your own cash, for free, for two or three months at a stretch.

The Trap: Revenue Growth That Increases Cash Stress

Here's the part that surprises a lot of owners. Landing bigger accounts with longer terms doesn't just create a one-time gap. It compounds.

Say you land three new customers over six months, each on net-60. In month one, you're covering delivery costs on the first contract with no cash in yet. By month three, you're covering delivery costs on all three while collections on the earliest one are only just starting to land.

Revenue on your P&L is climbing every month. Cash available to run the business is shrinking or flat. The bigger you grow this segment of customers, the wider that gap gets, until it's large enough to threaten payroll or vendor payments even in a genuinely strong quarter.

This is why "we're growing 30 to 35 percent year over year" and "we're stressed about cash" show up in the same sentence more often than you'd expect. Growth on paper and liquidity in the bank are not the same measurement, and a business can be excelling at one while struggling with the other.

What to Actually Do About It

You can't always negotiate away net-60 or net-90 terms, especially with a customer that has real leverage. What you can do is build the plan around the reality of those terms instead of hoping cash works itself out.

  • Model the cash impact before you sign, not after. Before accepting a large contract with extended terms, run the numbers on what it costs you to deliver during the gap between invoicing and payment. If the delivery cost is $150,000 and terms are net-60, you need to know you can cover that gap without straining the rest of the business.
  • Segment your AR by payment terms, not just by customer. A rolling cash forecast that treats every receivable as roughly 30 days out will consistently underestimate your real gap once a few net-60 or net-90 accounts are in the mix.
  • Use invoice factoring or AR financing selectively, not as a default. For a specific large contract with a known collection date, financing the gap can be the right call. Used as a permanent crutch across the whole business, it becomes an expensive way to paper over a planning problem instead of solving it.
  • Negotiate what you can, even at the margins. Partial upfront payment, milestone billing instead of a single invoice at completion, or a shorter term in exchange for a small discount are all worth asking for. Even shaving 15 days off effective collection time on your largest accounts moves real money.
  • Build the cash forecast around your actual mix of terms. If 40% of your revenue now comes from net-60 or longer customers, your forecast needs to reflect that blended reality, not an average that assumes everyone pays in 30 days.

The Real Lesson: Growth Changes Your Cash Flow Profile

The businesses that handle this well treat payment terms as a planning input, not a surprise. Every time your customer mix shifts toward larger accounts, your cash flow plan needs to shift with it. That's a financial visibility problem as much as a sales problem, and it's exactly the kind of gap that shows up when a growing business is being run on historical bookkeeping instead of a forward-looking financial view.

If you're chasing bigger logos this year, model the cash timeline before you sign, not after the first payroll crunch tells you the plan was wrong.
