Amazon Seller Working Capital Options: Keep Cash Flowing
What Is Working Capital?
Working capital is the cash you need to run your business day-to-day. For FBA sellers, it's the money that covers:
- Inventory replenishment between Amazon payouts
- Amazon PPC and Facebook ad spend
- Software subscriptions (Jungle Scout, Helium 10, inventory management)
- Shipping and logistics costs
- Unexpected expenses (returns, removals, account issues)
When working capital runs dry, growth stops. You can't restock fast-moving items. You can't scale ads. You can't launch new products. Working capital financing keeps the engine running.
Working Capital vs. Inventory Financing
| Factor | Working Capital | Inventory Financing |
|---|---|---|
| Purpose | Daily operations, cash flow gaps | Specific inventory purchases |
| Flexibility | Use for any business expense | Often restricted to inventory |
| Collateral | General business assets or none | The inventory itself |
| Amount | $5K–$500K | $10K–$1M+ |
| Repayment | Monthly or revenue-based | From inventory sales |
Top Working Capital Options for FBA Sellers
1. Business Line of Credit
The gold standard for working capital. Draw what you need, pay interest only on what you use, redraw as you repay.
| Lender | Max LOC | Rate | Min Revenue | Speed |
|---|---|---|---|---|
| Chase | $500K | Prime + 2–5% | $100K/yr | 2–4 weeks |
| Bluevine | $250K | 6.2–25% | $40K/yr | 1–3 days |
| Fundbox | $150K | 4.66–8.99% | $25K/yr | 1–2 days |
| OnDeck | $100K | 29.9–65.9% | $100K/yr | 1 day |
2. Revenue-Based Funding
Get a lump sum based on your sales history. Repay as a percentage of daily or weekly revenue.
| Lender | Amount | Cost | Requirements |
|---|---|---|---|
| Clearco | $10K–$10M | 6–12% flat fee | 6+ months, consistent sales |
| Wayflyer | $10K–$20M | 1.1–1.4× factor | $10K+/mo revenue |
| Onramp | $5K–$3M | 1.15–1.35× factor | 3+ months history |
| Liberis | $5K–$1M | Revenue share | Consistent revenue |
3. Business Credit Cards (0% APR)
For smaller working capital needs ($5K–$15K), 0% APR cards are the cheapest option. Use them for ads, software, and small inventory top-ups.
4. Amazon Lending
Amazon offers working capital loans directly through Seller Central to qualifying sellers.
- Amount: $1,000–$750,000
- Terms: 3–12 months
- Repayment: Deducted from Amazon payouts
- Pros: Fast, easy, integrated
- Cons: Invitation only, rates vary, Amazon controls repayment timing
5. Merchant Cash Advance (MCA)
Receive a lump sum in exchange for a percentage of future credit card sales or revenue.
- Amount: $5K–$500K
- Cost: Factor rates of 1.2–1.5× (very expensive)
- Speed: 24–48 hours
- Warning: MCAs are among the most expensive financing options. Annualized rates often exceed 50–100%. Use only as a last resort.
How Much Working Capital Do You Need?
Use this formula:
Working Capital Needed = (Monthly Operating Expenses × 2) + (Monthly Inventory Spend × 1.5)
Example:
- Monthly operating expenses: $5,000 (ads, software, shipping, fees)
- Monthly inventory spend: $10,000
- Working capital needed: ($5,000 × 2) + ($10,000 × 1.5) = $10,000 + $15,000 = $25,000
This gives you a 2-month operating buffer and covers 1.5 months of inventory, which is typical for FBA sell-through cycles.
Working Capital Management Tips
- Keep 3 months of expenses in reserve. Never draw your LOC or use cards for 100% of operating cash.
- Match financing term to use case. Don't use a 6-month revenue-based advance to fund a 12-month project.
- Monitor your cash conversion cycle. Track days from inventory purchase to cash in bank. Faster = less working capital needed.
- Negotiate better supplier terms. Net-30 from suppliers is free working capital. Net-60 is even better.
- Use Amazon's bi-weekly payouts strategically. Time inventory orders to arrive just after a payout hits your account.
Warning Signs You Need Working Capital
- □ You're delaying inventory reorders because cash is tight
- □ You're pausing profitable ads due to cash flow
- □ You're using personal funds to cover business expenses
- □ Your business credit cards are above 50% utilization
- □ You're paying suppliers late
- □ You can't take advantage of bulk discounts due to cash constraints

What's the cheapest working capital for FBA?
For amounts under $15K: 0% APR business credit cards. For $15K–$50K: a business line of credit from a bank. For $50K+: SBA loans or bank LOCs.
Can I get working capital with bad credit?
Revenue-based lenders (Clearco, Wayflyer) focus on sales history, not credit scores. MCAs also accept low credit but at very high cost.

Only if you have excess working capital after funding proven products. New products are risky. Fund them with cash or small test orders, not borrowed capital.
