Adding Products Manually

When to add a product by hand — and how it joins the same catalog and workflow.

Written lesson

The video for this lesson is in production — the written version below covers the full concept.

What it is

New Catalog Product is the by-hand path into the catalog: a modal where only the product title is required, plus two attach points — Amazon Listings and Vendor Offers — using the same wizards as the rest of the app. A manually created product is a first-class catalog product: same margin math, same quotes and POs, same history.

The Amazon side is a search, not a form: search by ASIN, title, UPC, or brand across ten marketplaces, select one or more listings, set pack sizes, confirm. The first ASIN you attach auto-fills the product’s title, brand, and image, and full pricing data syncs in the background.

Why it exists

Feeds are the bulk path; manual is the one-off path. A product a vendor mentioned on a call, an ASIN you spotted while researching, a sample from a trade show — none of these should wait for a spreadsheet to exist before you can track margin on them.

The manual path is also where you teach the matcher. Every UPC or EAN you record — on the offer or in the product’s barcodes — becomes a match key, so a future vendor feed carrying that barcode lands on this product instead of creating a duplicate.

How to use it

  1. 1

    New Catalog Product

    On the Product Catalog page, click New Catalog Product. Type a title — that is the only required field.

  2. 2

    Attach the Amazon listing

    Add under Amazon Listings → search by ASIN, title, UPC, or brand → pick the marketplace → set units per listing for multipacks. Title, brand, and image auto-fill from the first ASIN.

  3. 3

    Add the vendor offer

    Add under Vendor Offers → pick the vendor (or Create New Vendor inline) → enter the Vendor SKU and List Price. For case-packed SKUs, tick Multi-unit SKU and set Units per SKU — the form shows the effective unit cost live.

  4. 4

    Record the barcode

    Fill the UPC / EAN field on the offer, or use Manage Barcodes on the product. 8–14 digits; the type (UPC, EAN, or GTIN) is inferred automatically.

  5. 5

    Create Catalog Product

    The product drops into the catalog with margins computed like any other row — ready for quotes, POs, and future feeds.

Common questions

When should I add manually instead of uploading a feed?

When the product exists before the spreadsheet does: one-off finds, a vendor’s verbal price, restock-report discoveries. If you have a file with many rows, upload it as a vendor feed — matching does the bulk work.

What if the ASIN is already in my catalog?

VendorDelta blocks the duplicate and points you to the existing product — open it and add your offer there. The same ASIN on a different marketplace is a separate listing and can be added.

Why record a UPC/EAN if the product is already matched?

Because barcodes are what future matching runs on. A feed row or an Amazon sync carrying that barcode auto-resolves to this product. Barcodes are product-level, shared across the product’s listings, and each shows its source (Manual, Vendor, or Amazon).

I attached the offer to the wrong product — now what?

Move it: every offer has a Move vendor offer action that relocates it to another catalog product, and the offer keeps its full history — quotes, purchase orders, and feed matches move with it. Moving onto an archived product revives that product.
