Each Marketplace Has Different Rules

Amazon's Vendor Agreement is different from Shopify's Merchant Agreement, which differs from Etsy's Seller Policy. Beyond marketplaces, you need vendor contracts with suppliers, fulfillment partners, and dropshippers.

Supplier / Wholesale Agreement Essentials

Dropshipping Agreement Essentials

3PL / Fulfillment Agreement

Third-party logistics agreements need: storage fees, pick/pack rates, shipping costs, inventory accuracy guarantees, damages/lost inventory liability, and exit transition support. Read the fine print — minimum monthly fees and onboarding fees often hide.

FAQ

Do I need a contract with my Amazon supplier?

Yes. Even if buying through Alibaba, get a written agreement with quality standards, payment terms, and IP protections (especially for private label). Amazon's TOS doesn't cover your supplier relationships.

What's the difference between dropshipping and 3PL?

Dropshipping: supplier ships directly to customer. 3PL: you ship inventory to fulfillment center, they ship to customers. 3PL is faster (you control inventory) but requires upfront inventory investment.

Can my supplier raise prices mid-contract?

Only if your contract allows it. Negotiate price-lock periods (typically 6-12 months) with renegotiation windows. Otherwise suppliers can raise prices anytime, killing your margins.
