A business line of credit is one of the more flexible financing tools out there, and also one of the easiest to misunderstand. People conflate it with a term loan, miss how the draw period works, or don’t realize the interest math is different from a credit card’s. This section exists to fix that — clear explanations of how the product works and how to use it well, written by someone who used to underwrite them.
No invented rates or fees live in these guides. Where costs come up, we explain the mechanics and point you to the rates section and to named sources, rather than quoting a number that won’t match your offer.

When you’re ready to act
Once you understand the product, the next step is matching it to a lender that fits your business. Read the eligibility requirements to see where you stand, then compare lenders in the reviews section.
If you’d rather see real options without applying one lender at a time, a marketplace matches a single application to multiple lenders.
Lendio is a marketplace, not a lender. Checking your options uses a soft credit pull that does not affect your score; if you accept an offer, a matched lender may run a hard pull at underwriting, only with your consent (per BizBee Funding, 2026).
