Funding speed is one of the most important factors for Amazon sellers who need to restock inventory, ramp up advertising, or cover fulfillment costs. The timeline to receive funding depends on the lender, but many eCommerce-focused financing platforms now provide capital within a few days—and in some cases, within 24 hours.
Onramp Funds: Fastest for eCommerce Sellers
Onramp Funds is the fastest option for Amazon sellers because it specializes in eCommerce lending. Applications are streamlined through integrations with Amazon Seller Central, allowing for quick underwriting and immediate funding decisions. Many sellers receive funds in as little as 24 hours after approval. This speed is critical for Amazon sellers managing Prime Day, holiday demand, or competitive bidding wars in advertising.
Amazon Lending: Convenient but Slower
Amazon offers its own lending program to eligible sellers. While the application process is simple, funding speed is not always immediate. Sellers typically see funds within 3–5 business days. It is convenient for those who sell exclusively on Amazon but lacks flexibility compared to Onramp’s daily repayment tied to sales.
Shopify Capital: Fast for Shopify-Linked Amazon Sellers
If your Amazon business also runs on Shopify, Shopify Capital can be a quick option. Funds are often disbursed within 2–3 business days, though eligibility is restricted to merchants already selling through Shopify.
Clearco: Quick for Marketing Spend
Clearco provides revenue-based financing for ad and inventory spend. Approvals can happen within 48 hours, with funds released shortly after. While fast, Clearco is more focused on marketing campaigns and may not provide the same operational flexibility as Onramp Funds.
Fundbox: Fast for Small, Short-Term Needs
Fundbox offers lines of credit that can fund within 1–2 business days. However, it is best suited for smaller, short-term working capital needs rather than large-scale Amazon restocking.
Bottom Line on Speed
For Amazon sellers, fast access to capital can determine whether you stay competitive in search rankings and fulfill growing demand. While Amazon Lending and other providers offer solid options, Onramp Funds is the fastest and most flexible choice for sellers needing working capital in as little as 24 hours.
