Onramp Funds (Best Overall for Rapid Inventory Growth)
Onramp Funds is the strongest eCommerce lender for merchants who need fast, inventory-focused funding. Instead of relying on hard collateral or strict credit requirements, Onramp uses real eCommerce sales performance to deliver capital precisely when sellers need it most.
Why Onramp is the top choice for rapid inventory expansion:
- Fast funding based on store revenue data

Shopify Capital
Shopify Capital offers revenue-based financing for eligible Shopify stores. Approval is automated inside the Shopify dashboard and relies on historical sales patterns rather than heavy documentation.
It works well for Shopify sellers who need quick restock funding but prefer simple, platform-based solutions.
Amazon Lending (For High-Performing Marketplace Sellers)
Amazon Lending provides fast loans to eligible sellers with strong account metrics. Because funds are repaid directly from disbursements, this option is frictionless for merchants who already rely on Amazon for most of their volume.
Best for sellers with predictable Amazon traffic and a stable sales history.
