If they have the limit and can pay it off quickly, cards can work. But cards often come with a hidden 2–4% "card tax" — either the vendor bakes acceptance costs into pricing, charges a surcharge, or offers an ACH discount you miss out on. Plus, cards can spike utilization and limits can tighten right when a brand is scaling. Portless Capital is a clean, predictable plan that avoids card-rail costs and keeps credit utilization from getting ugly. On a $25,000 invoice, a ~3% embedded card cost is ~$750 — that adds up fast.
