What is Concentration limit
Definition
A cap on how much of your funded ledger can sit with one client, commonly 25% to 35%. Invoices above the cap are funded at a lower rate or not at all.

In practice
New agencies usually win one anchor client first, which is exactly the shape funders limit. Winning the second and third client is a funding decision as much as a sales one.
Ask for the concentration position in writing before you sign, and re-check it before any large rollout — a single win can push you over the line and shrink available cash at the worst moment.
