What it is, how it works
Trade and import finance is funding that pays your suppliers for stock or goods before you have sold them or been paid by your own customers. Instead of finding the full cost up front, a funding partner settles the supplier invoice on your behalf, and you repay once the goods have been sold and the money has come in. It exists to bridge the most awkward part of running a product business: the stretch of time between committing cash to a purchase and finally seeing the sale convert to cash in the bank.
The easiest way to picture it is as the trade cycle. You win or place an order, you pay the supplier, the goods are produced and shipped, they arrive and sit in stock, you sell them, and eventually your customer pays you. Every one of those steps can take weeks, and for imported goods the shipping and lead times can stretch that out further. Trade finance covers the early part of that cycle so the gap between paying out and being paid does not stall the whole operation.
In practice the funding is closely tied to real transactions rather than being a general loan. It commonly takes the form of import finance that pays overseas suppliers, purchase-order finance that funds confirmed customer orders you could not otherwise fulfil, or inventory and stock finance secured against goods you hold. Because it follows the goods, the amount available tends to move up and down with your buying, which is what makes it a natural fit for businesses whose cash is constantly cycling through stock.
