Contractor cash flow: the gap between invoice and payment

Contractors live on net terms — invoice today, get paid in 30 or 60 days. The gap between work done and money landed is where contractor cash flow dies. A dated forecast puts every invoice on its expected date and shows the gaps before they bite.

The buffer rule for contractors

Maintain a buffer equal to two months of operating costs — it absorbs late payments, slow net terms, and the month the invoice pipeline thins. The calendar shows the buffer in real time: rising after payments, draining in gaps, and the trigger point if it gets low.

Cash flow levers

  • Request deposits: 30–50% upfront on larger projects
  • Shorten terms where clients allow: Net 15 instead of Net 30
  • Chase at day 30 — the projection makes the cost of lateness visible
  • Spread large bills across the gap months
