Before every peak season, sellers receive financing offers: from marketplaces, payment companies, banks and online lenders. Some are good value; others cost far more than they appear. The difference is usually hidden in how the price is quoted. This guide shows how to put any offer on the same footing so you can compare them properly.

The main types of seller financing

Type	How it works	How the cost is usually quoted
Term loan	Fixed amount, fixed repayment schedule	Interest rate or APR, plus any fees
Line of credit	Draw what you need up to a limit; pay interest on what you use	Interest rate on drawn balance, sometimes a draw fee
Merchant cash advance / sales-based financing	Lump sum repaid as a share of future sales or payouts	A fixed fee or "factor rate" (for example 1.10)
Inventory or purchase-order financing	Funds a specific order, repaid when goods sell	Fee per period or interest rate

On Amazon, Amazon Lending connects eligible sellers with third-party providers offering lines of credit, term loans and merchant cash advances.

Why a factor rate can be misleading

A cash advance with a factor rate of 1.10 means you repay $1.10 for every $1.00 received: a $50,000 advance costs $5,000. That sounds like 10%, but the annual cost depends on how fast you repay. With sales-based repayment, strong sales mean faster repayment and a higher effective cost:

The true annual percentage rate (APR) is even higher than these simple figures, because you are repaying throughout the term and your average balance is lower than the full advance.

What the law requires lenders to disclose

Some states require commercial lenders to show APR-style disclosures. In California, regulations under SB 1235 took effect on December 9, 2022 and require providers of commercial financing offers of $500,000 or less to disclose items including the amount financed, the estimated annual percentage rate, the finance charge, payment terms and prepayment terms, as summarized by the National Law Review and Consumer Finance Monitor. The rules cover sales-based financing such as merchant cash advances. Whether a disclosure applies to you depends on your state and the provider, but you can always ask for the same information.

Five questions to ask about every offer

1. What is the total amount I will repay? Including every fee.
2. What is the estimated APR? Ask for it in writing, even if not legally required.
3. How is repayment collected? Fixed payments, or a percentage of each payout? How large a share?
4. Is there a prepayment discount? With many advances, paying early does not reduce the fee.
5. What happens if sales drop? Are there minimum payments, penalties or effects on future offers?

Tip: Divide the total fee by the expected months to repay and multiply by 12. If that simple number is already higher than your profit margin on the inventory, the financing will lose money.

When financing makes sense

• Proven products. Funding reorders of a best seller with a known margin and sell-through rate.
• Seasonal peaks. Buying Q4 inventory that you are confident will sell in Q4.
• Short cash gaps. Bridging the time between paying suppliers and receiving marketplace payouts.

It is risky for testing new products, covering ongoing losses or financing slow-moving stock.

A simple comparison worksheet

1. Write down each offer's amount, total repayment and expected repayment period.
2. Calculate the simple annualized cost for each: fee ÷ amount × 12 ÷ months.
3. Ask each provider for its estimated APR and compare.
4. Check how repayments affect your weekly or bi-weekly payouts during peak season.
5. Choose the offer with the lowest total cost that still fits your cash flow.

每到旺季前，卖家都会收到各种融资邀约：平台、支付公司、银行和网络贷款机构。有的划算，有的成本远比看上去高。差别往往藏在报价方式里。本文教你把各种方案换算到同一标准，真正做到可比。

常见的卖家融资类型

类型	运作方式	通常的报价方式
定期贷款	固定金额、固定还款计划	利率或年化利率（APR），另加费用
循环额度	在额度内按需提取，只为已用部分付息	已用余额的利率，有时有提款费
垫资 / 按销售额还款融资	一次性拿到资金，按未来销售额或回款比例还款	固定费用或“系数”（如 1.10）
库存或采购订单融资	为特定订单提供资金，货卖出后还款	按期收费或利率

在亚马逊，亚马逊贷款为符合条件的卖家对接第三方资金方，提供循环额度、定期贷款和垫资产品。

为什么“系数”容易误导

系数 1.10 的垫资，意味着每拿到 1 美元要还 1.10 美元：5 万美元垫资的费用是 5,000 美元。看起来是 10%，但年化成本取决于还款速度。按销售额还款时，销量越好还得越快，实际成本越高：

真实的年化利率（APR）比图中的简单数字更高，因为你在整个期限内持续还款，平均占用的资金低于垫资全额。

法律要求披露什么

部分州要求商业融资机构提供类似 APR 的披露。在加州，依据 SB 1235 制定的法规于 2022 年 12 月 9 日生效，要求对 50 万美元及以下的商业融资报价披露融资金额、估算年化利率、融资费用、还款条款和提前还款条款等信息，据 National Law Review 和 Consumer Finance Monitor 的整理，规则覆盖垫资等按销售额还款的融资。是否适用取决于你所在的州和资金方，但你随时都可以要求对方提供同样的信息。

每个融资方案都要问的 5 个问题

1. 总共要还多少？包括所有费用。
2. 估算年化利率是多少？即使法律不要求，也请对方书面提供。
3. 如何扣款？固定还款，还是按每笔回款比例扣？比例多大？
4. 提前还款有优惠吗？很多垫资提前还清也不减费用。
5. 销量下滑怎么办？有无最低还款、罚金，或影响后续额度？

小提示：用总费用除以预计还款月数再乘以 12。如果这个简单数字已经高于这批货的利润率，这笔融资就是亏的。

什么时候适合融资

• 已验证的产品：为利润率和动销率都清楚的爆款补货。
• 季节性高峰：备有把握在 Q4 卖完的 Q4 库存。
• 短期资金缺口：衔接付款给供应商与平台回款之间的时间差。

用于测新品、填补持续亏损或为滞销库存融资，风险很高。

简单对比表

1. 写下每个方案的金额、总还款额和预计还款期。
2. 分别计算简单年化成本：费用 ÷ 金额 × 12 ÷ 月数。
3. 向每家资金方索取估算 APR 并对比。
4. 检查旺季期间还款对每周或每两周回款的影响。
5. 选择总成本最低、同时现金流能承受的方案。
