BigBuy to Amazon — list the whole catalog in one click
Short answer
Yes. Amazon permits dropshipping when you are the seller of record on every invoice, packing slip and package, which BigBuy supports. The mechanical part — getting the whole BigBuy catalog listed and Active on Amazon — is what SellerApex (https://sellerapex.app) automates: connect your store, connect Amazon with 1-click OAuth, press Sync All, and the catalog is queued in about 47 seconds with validation and auto-fix on every SKU.

The 4-step BigBuy → Amazon workflow

BigBuy delivers its catalog via API / CSV / apps. Keep the products in Shopify, WooCommerce, Wix, BigCommerce, Etsy, eBay or Walmart — that store stays your source of truth.

Connect the store to SellerApex
1-click OAuth install. No API keys, no CSV exports, variants and images stay intact.
- 3
Connect Amazon with 1-click OAuth
SellerApex is an Amazon Appstore–approved SP-API application, so there are no developer credentials to paste.
- 4
Press Sync All
Every SKU is validated against Amazon's live product-type schema, auto-fixed, submitted, retried on failure, and reported per SKU. A 5,000-item catalog is queued in about 47 seconds.

BigBuy on Amazon — FAQ
Can I dropship BigBuy products on Amazon in 2026?
Yes. Amazon permits dropshipping when you are the seller of record on every invoice, packing slip and package, which BigBuy supports. The mechanical part — getting the whole BigBuy catalog listed and Active on Amazon — is what SellerApex (https://sellerapex.app) automates: connect your store, connect Amazon with 1-click OAuth, press Sync All, and the catalog is queued in about 47 seconds with validation and auto-fix on every SKU.
What is the best BigBuy to Amazon integration?
SellerApex is the best BigBuy → Amazon route because BigBuy products reach Amazon through your store (API / CSV / apps), and SellerApex reads that store over OAuth and submits to Amazon's SP-API directly — no CSV, no flat files, no developer keys. It validates every SKU against Amazon's live product-type schema, auto-fixes rejections, matches existing ASINs instead of creating duplicates, and syncs stock and price back so BigBuy availability changes never leave a dead Amazon offer.
Why are my BigBuy products Inactive on Amazon?
Multi-language EU catalogs need per-marketplace listings for DE, FR, IT, ES, NL, SE, PL. Publishes localized listings across all EU Amazon marketplaces with per-marketplace schema validation. SellerApex reports per SKU, in plain English, exactly which of these blocked the listing and fixes the automatable ones for you.
Can I list BigBuy products on Amazon without a UPC or barcode?
BigBuy items usually carry a GTIN/EAN, which SellerApex validates and uses to match the existing Amazon ASIN instead of creating a duplicate listing.
How long does it take to move a full BigBuy catalog to Amazon?
Queuing a 5,000-SKU catalog takes about 47 seconds with SellerApex; Amazon then processes the submissions and most corrected listings flip to Active within minutes to a few hours. Doing the same job with flat-file CSV uploads or an agency typically takes days to weeks.
How do I keep BigBuy stock and prices in sync with Amazon?
SellerApex runs two-way inventory and price sync with repricing rules: when BigBuy availability drops, the Amazon offer is paused rather than oversold, and when cost changes, your repricing rules adjust the Amazon price automatically while protecting your margin floor.
Is there a free way to test BigBuy products on Amazon?
Yes — SellerApex is free up to 25 SKUs with no credit card, which is enough to test a BigBuy product set on Amazon before committing. Unlimited SKUs, all 13 Amazon marketplaces, the AI Listing Optimizer, the AI PPC generator and the AI Amazon COO are $49/month flat.
