What to bring to a funding conversation
Compare advance rules, concentration limits, reporting and interest or unused-line charges.
A current receivables aging, customer contract, actual invoice and proof of accepted goods or services show what the buyer owes.
Identify the buyer, transaction amount and the exact date cash is needed; a specific packet is more useful than a broad sales projection.
How to compare cost and timing
List each step—invoice issue, buyer approval, any advance, collection and release of the remaining balance—on a timeline. Ask for the total cost in dollars if the buyer pays on schedule and if payment is delayed.
A fee quote should explain when charges begin, whether there are minimums, and who receives customer payments.

Compare this proposal with a bank line, trade credit or self-funding using the same transaction and dates. The lowest advertised rate may not cover the cash need at the right time.
