Inventory Financing for E-commerce Brands: Purchase Orders, Lines and Revenue-Based Capital

By MercFinancial · Published 2026-10-22 · Updated 2026-10-21

Inventory financing for e-commerce covers the months between the supplier deposit and the sale: PO financing for confirmed orders, inventory lines against landed cost, supplier terms and revenue-based advances.

Inventory financing for an e-commerce brand funds the gap between paying the supplier and selling the goods, and it comes in four forms: purchase order financing that pays the factory against a confirmed order, an inventory line of credit that advances against the landed cost of stock on hand, supplier terms that defer the payment itself, and a revenue-based advance that funds the buy from future sales. Each one covers a different part of the cycle, and each has a different answer to the question lenders ask first: what happens to the goods if they do not sell. A brand that owns its inventory, knows its landed cost by SKU and can show how fast each product turns has a choice. A brand that cannot has an advance.

This guide covers the cash cycle the financing has to bridge, each product and the orders it fits, how lenders value inventory, an illustrative comparison of cost against turn, the mistakes that get inventory files declined, and where MercFinancial fits.

Inventory money is priced by the month. The only question that matters is how many months the goods will sit before they turn.

The cash cycle an e-commerce brand has to bridge

An e-commerce brand pays for its goods long before it sells them. A typical cycle runs from a deposit to the manufacturer at order, to the balance at shipment, through weeks in transit and customs, to receiving at the warehouse or fulfillment center, and then through weeks or months of sell-through before the marketplace pays out. A brand that orders a season's stock has its cash locked up for a quarter or more, and growth makes it worse.

That gap is what inventory financing covers, and the structure has to match the part of the cycle it is funding. Paying the factory is a different problem from carrying stock already on the shelf, and both are different from funding a wholesale order a retailer has already signed. Lenders ask three questions of every inventory request: who owns the goods and where are they, what did they cost landed, and how fast will they turn. The head-term guide to e-commerce business loans covers the rest of the file.

Purchase order financing: confirmed orders only

Purchase order financing pays the supplier directly for finished goods against a confirmed purchase order from a creditworthy buyer. The PO funder is repaid when the buyer pays, often through a factor that takes over the invoice at shipment. It funds the whole order, needs little balance-sheet strength from the brand, and is priced per 30 days on the amount advanced.

The limit is the word confirmed. A direct-to-consumer brand with a demand forecast and an ad plan does not have a purchase order, and most PO funders will not fund inventory that has not been sold to someone yet. PO financing fits the e-commerce brand that also sells wholesale: a national retailer's order, a distributor's order, a large corporate or institutional order. It also wants finished goods from a reliable manufacturer, not raw materials or a product still in development, and margins wide enough to absorb the fee. The guide to invoice factoring versus PO financing shows how the two hand off to each other on one order.

Inventory lines, supplier terms and revenue-based advances

Inventory lines of credit. An asset-based lender advances a percentage of the landed cost of eligible inventory and lets the brand draw and repay as stock turns. Advance rates are set product by product and are higher on finished, fast-moving goods than on slow or seasonal SKUs. The lender takes a lien on the inventory, requires reports from the warehouse or 3PL, and audits periodically. It suits an established brand with a year or more of sales history, clean SKU-level data and inventory it owns outright.

Supplier terms. The cheapest inventory financing is the one the manufacturer provides. Net terms of 30 to 60 days after shipment, a smaller deposit, or payment on sell-through are negotiated with a track record of paid orders, and a standby letter of credit can persuade a supplier to extend them earlier. Ask before borrowing.

Revenue-based advances. A funder advances a sum against trailing sales and collects a fixed share of receipts until a set amount is repaid. It needs no confirmed order, no lien on inventory and no audit, which is why it is the inventory money most direct-to-consumer brands actually use. Against that, it is the most expensive of the four and is repaid whether or not the goods sell, so it fits a seasonal buy with a short, predictable turn. The guide to how revenue-based financing works covers the cost.

The SBA's CAPLines program offers a working capital line sized to receivables and inventory, the long-term answer for an established brand with tax returns and margins.

How a lender values e-commerce inventory

Inventory is valued at cost, never at retail, and the cost is landed: the factory price plus freight, duty, customs brokerage and inbound handling. A brand that cannot produce landed cost by SKU is asked to build it before anything is advanced. From that base the lender excludes what it would not want to own: aged stock, seasonal goods past their season, returns and refurbished units, work in process, packaging, and anything held on consignment or under a supplier's lien.

Where the goods sit matters as much as what they are. Stock in a brand's own warehouse can be inspected and, if needed, taken. Inventory in a 3PL needs a bailee waiver so the lender's lien survives. A marketplace fulfillment center is the hardest case: the brand owns the goods, but the marketplace controls them, and most inventory lenders discount that stock heavily or lean on the payouts instead. The guide to funding for Amazon sellers and dropshippers covers that structure.

Illustrative example: cost against turn

Illustrative example, hypothetical and rounded: a brand needs $100,000 to pay a supplier for goods that will sell for $250,000, and has two ways to fund it.

Neither column is a quote, and the funding source sets the real numbers. The point is the shape. Money priced by the month rewards a fast turn and punishes a slow one, so a brand should know its sell-through before it chooses. A fixed repayment costs the same whether the goods fly or sit, which is tolerable on a sure seasonal buy and painful on a speculative one. The cheapest version of either is the one repaid quickly, which is why inventory financing and inventory discipline are the same conversation.

Mistakes that get inventory files declined

• Financing stock that is already slow. Lenders read the aging report, and a request to advance against SKUs that have sat for six months is declined or heavily discounted.
• No landed cost. Factory price alone understates the investment and overstates the margin, and a lender will not value inventory on it.
• Asking a PO funder to fund a forecast. Without a confirmed order from a creditworthy buyer there is nothing to finance.
• Borrowing long for a short turn, or short for a long one. A term loan on a 60-day buy wastes interest, and an advance on a year of stock starves the business.
• Stacking advances to fund growth. Each one collects from the same receipts, and the third one usually ends the brand's access to anything cheaper.

Where MercFinancial fits

MercFinancial is a commercial funding broker in Houston, not a lender. An inventory request starts with the cycle: what is being bought, from whom, for what orders, at what landed cost, and how fast it turns. That decides whether the file is a purchase order financing file, an inventory line file, a revenue-based file, or a supplier conversation the brand should have first. From more than 160 funding sources, the ones whose policy covers the brand's category and the structure are identified, one file goes to all of them, and the offers are compared on cost over the expected turn. Whether a brand qualifies, and on what terms, depends on the funding source. Stephanie, the AI lending assistant, pre-qualifies a request in a few minutes with a soft credit pull, and a free 30-minute call with a funding specialist follows.

Frequently Asked Questions

How does inventory financing work for an e-commerce business?

A lender pays for, or advances against, the goods a brand is buying or holding, and is repaid as the goods sell. Purchase order financing pays the supplier against a confirmed order, an inventory line advances a share of landed cost on stock in the warehouse, and a revenue-based advance funds the buy from future sales. Supplier terms defer the payment itself.

Can I get purchase order financing for an online store?

Only for confirmed orders. PO funders pay a manufacturer for finished goods sold to a creditworthy buyer, such as a retailer or distributor, and are repaid when that buyer pays. A direct-to-consumer demand forecast is not an order, so a brand that sells only to consumers uses an inventory line, supplier terms or a revenue-based advance instead.

What advance rate do lenders give on e-commerce inventory?

It varies by lender and by product, and it is always a share of landed cost, never retail. Fast-moving finished goods in the brand's own warehouse get the highest rates, slow, seasonal or marketplace-held stock the lowest, and aged inventory, returns and consigned goods are usually excluded entirely. The lender's audit and the aging report decide the number.

Is revenue-based financing a good way to buy inventory?

For a seasonal buy with a short, predictable sell-through, it can be. The advance needs no lien, no audit and no confirmed order, and it funds in days. It costs more than any other inventory product and is repaid whether or not the goods sell, so it is a poor fit for speculative stock or a year's supply. Know the turn before you take it.

Can I finance inventory held in a marketplace fulfillment center?

It is harder. The brand owns the goods, but the marketplace controls them, so most inventory lenders discount that stock heavily or decline it and underwrite the marketplace payouts instead. Inventory in the brand's own warehouse, or at a 3PL that signs a bailee waiver, is financed far more readily, and so is inventory financed before it ships in.
