E-commerce Business Loans: Inventory, Ad Spend and Growth Capital

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

E-commerce brands are funded on their numbers, not their assets: inventory and purchase order financing, revenue-based capital, lines of credit, platform programs and SBA loans. What each funds and what lenders check.

E-commerce business loans exist in five forms: inventory and purchase order financing that pays the supplier, revenue-based capital advanced against sales and repaid from them, lines of credit and term loans underwritten on deposits and owner credit, the capital programs the marketplaces and storefront platforms offer their own sellers, and SBA 7(a) loans for established brands with tax returns and margins. An online retailer, marketplace seller, subscription box or direct-to-consumer brand is eligible for all of them in principle. What lenders hesitate over is not the channel but the absence of hard assets, the dependence on a platform and an ad auction, and the returns and chargebacks that come with selling to people who never touch the product before they buy.

This guide covers why banks are cautious with e-commerce, each product and what it is for, the numbers a lender reads in an e-commerce file, an illustrative contribution-margin calculation, the mistakes that get online brands declined, and where MercFinancial fits as a broker across more than 160 funding sources.

In short
  • E-commerce businesses are eligible for SBA 7(a) loans and, apart from CBD and other restricted categories, are not on the lists several large online lenders publish.
  • E-commerce brands are financed on inventory and purchase orders, on revenue-based advances against sales, on deposit-based lines, on platform programs, and on SBA loans once established.
  • Lenders underwrite an e-commerce business on gross and contribution margin, return and chargeback rates, platform concentration and inventory turns rather than on collateral.
  • Ad spend is the cost an e-commerce lender watches most closely, because a brand whose growth depends on a rising cost per acquisition can lose its margin in a quarter.

An e-commerce brand has no collateral a lender can sell, so the lender buys the numbers instead, and the numbers have to foot.


Why banks are cautious with e-commerce brands

A bank's three questions are cash flow, collateral and the owner. An e-commerce brand answers the first with numbers that move every month and the second with almost nothing. Inventory is the only physical asset, and a bank cannot easily value, inspect or sell a warehouse of branded goods, especially when the goods sit in a third-party logistics warehouse or a marketplace fulfillment center under someone else's contract.

Then there is the channel. A brand that sells through one marketplace can lose its account, and with it its revenue, over a policy dispute the lender will never see coming. Growth bought in an ad auction can stop the week the cost per acquisition rises. Returns, refunds and chargebacks are a cost of selling at a distance, and the card networks run chargeback monitoring programs with thresholds low enough that one bad month on a continuity offer can put a merchant into a program and threaten its processing. A subscription brand adds churn to the list. None of this is new to the lenders who write e-commerce every week. It is new to a community bank, which is why the bank asks for real estate and the brand looks elsewhere. The guide to why lenders flag e-commerce and subscription businesses takes each flag in turn.

The capital that exists for e-commerce, product by product

Most e-commerce files use two of these at once, one for inventory and one for everything else.

  • Inventory and purchase order financing. Pays the supplier for goods the brand has sold or will sell. Purchase order financing needs a confirmed order from a creditworthy buyer, so it fits wholesale and retailer orders rather than direct-to-consumer demand. Inventory lines advance against the landed cost of eligible stock and are audited. The guide to inventory financing for e-commerce covers the math.
  • Revenue-based financing. A funder advances a sum against trailing sales and takes a fixed share of daily or weekly receipts until a set amount is repaid. It is fast, needs no collateral, and costs more than a term loan. It fits an inventory buy ahead of a season or an ad push with a known payback, not a permanent working capital gap.
  • Lines of credit and term loans. Unsecured lines and term loans from online and bank-statement lenders are underwritten on twelve months of deposits and the owner's credit. A line is the right tool for the gap between paying a supplier and collecting from a marketplace.
  • Marketplace and platform programs. The large marketplaces and storefront platforms offer capital to their own sellers, usually by invitation based on account history, repaid automatically out of payouts. Convenient, and limited to that channel's sales.
  • SBA 7(a) loans. Open to an established e-commerce business with tax returns, margins and an owner who can carry a personal guaranty. Proceeds can refinance expensive advances, fund inventory and working capital, or buy a warehouse. The SBA's CAPLines program includes a working capital line built around receivables and inventory for businesses whose cash cycle justifies it.

Equipment financing applies only to brands that manufacture, pack or fulfill in-house, and a brand buying its own warehouse moves to commercial real estate lending.

What a lender reads in an e-commerce file

1
Platform and payout reports

Twelve months of sales, refunds and payouts exported from each marketplace and storefront, reconciled to the bank statements. Lenders want the platform's numbers, not a spreadsheet summary of them.

2
Margins

Gross margin by product line and contribution margin after shipping, fulfillment, payment processing, returns and advertising. A brand that cannot state its contribution margin per order is not ready to borrow.

3
Returns and chargebacks

Return and refund rates by month, the chargeback ratio from the processor, and any card-network monitoring history. A continuity or free-trial offer gets extra attention here.

4
Concentration and inventory

The share of revenue from each channel and the top products, inventory aging by SKU, landed cost, and the 3PL or fulfillment agreement that says who holds the goods and on what terms.

5
Owner credit, tax returns and ad accounts

Personal credit, business and personal returns for an SBA or bank file, and the ad accounts, since lenders increasingly read customer acquisition cost and payback alongside the financials.

The guide to what lenders review on a business loan covers the general package. For e-commerce, the platform exports and the per-order margin are what separate a fundable file from a declined one.

Illustrative example: the contribution margin a lender wants to see

Illustrative example, hypothetical and rounded: a direct-to-consumer brand with an average order of $100 shows a lender what each order leaves behind.

Per orderAmount
Revenue$100
Cost of goods, landed$35
Shipping and fulfillment$12
Payment processing, returns and chargebacks$8
Advertising per order$30
Contribution margin$15

At $15 an order, the brand can service debt only if volume holds and the ad cost does not climb. If advertising rises to $40 an order, the contribution falls to $5 and the same loan is unpayable. That is the calculation an e-commerce lender runs before anything else, and it is why the ad account is in the file. A brand whose repeat customers arrive without ad spend shows a second, better margin on those orders, and a lender gives credit for it when the data shows the split. The guide to how revenue-based financing works shows how the same margin decides whether an advance pays for itself.

Mistakes that get e-commerce files declined

  • Stacking advances. Two or three revenue-based advances collecting from the same payouts is the most common reason an e-commerce file is declined for anything better.
  • Spreadsheet revenue. Numbers that do not reconcile to the platform exports and the bank statements are treated as unverified.
  • One channel. A brand with almost all of its revenue on one marketplace is underwritten as if that account could close tomorrow, because it could.
  • Financing dead stock. Asking an inventory lender to advance against slow or seasonal SKUs that are already aging in the warehouse.
  • Ignoring the chargeback ratio. A merchant in a card-network monitoring program is a processing risk first and a credit risk second, and lenders check.
  • Applying for SBA money too early. A 7(a) lender wants tax returns that show the margin, and a brand in its first year is better served by a line or an advance sized to a specific buy.

Frequently Asked Questions

Can an e-commerce business get an SBA loan?

Yes. Online retailers and marketplace sellers are not excluded under 13 CFR 120.110, and an established brand with tax returns, consistent margins and an owner who can sign a personal guaranty can use a 7(a) loan for inventory, working capital, refinancing advances or a warehouse. The lender's own credit policy decides, and most want a track record rather than a first-year brand.

What do lenders look at for an online store?

Platform payout reports reconciled to bank statements, gross and contribution margin per order, return and chargeback rates, channel and product concentration, inventory aging and landed cost, the fulfillment agreement, and the owner's credit. Advertising cost per order gets particular attention, because a rising ad cost can erase the margin that services the debt.

Is revenue-based financing good for an e-commerce business?

For a specific, short payback, yes. An advance against sales that funds a seasonal inventory buy or an ad push with known returns can pay for itself. As a permanent working capital source it is expensive, and stacking two or three advances is the most common reason an e-commerce brand is declined for cheaper money later. Compare the total repayment to the margin the money will earn.

How much can an e-commerce business borrow?

It depends on the product and the funding source. Revenue-based funders size an advance to trailing monthly sales, inventory lenders to the landed cost of eligible stock, deposit-based lenders to average monthly deposits, and SBA lenders to repayment ability shown in tax returns. A brand with clean platform data and a documented contribution margin is offered more, at a lower cost, than one with the same revenue and no reconciliation.

Why was my online business declined by the bank?

Usually because the bank could not find collateral or could not verify the numbers. E-commerce brands hold inventory a bank cannot easily value, sell through platforms the bank does not control, and show margins that move with ad costs. A bank's decline is not a decline by the lenders that write e-commerce on platform data and margins, so the next step is a file built for them.

Nothing here is a commitment to lend or an offer of credit, and financing is for business purposes only. Any example in this guide is hypothetical and illustrative; actual terms and outcomes vary. Dietary supplements are regulated by the FDA and the FTC; card-not-present businesses are subject to card-network chargeback programs; financing availability depends on the funding source's policies.
