Create a product and cross-list it with ResaleOS

This guide walks you through creating a product in ResaleOS, letting AI do the heavy lifting, and posting to multiple marketplaces in one go.

Before you start

  • Connect your sales channels (eBay, Etsy, Poshmark, Mercari, Shopify, Facebook Marketplace, Pinterest, etc.).
  • Have clear photos of your item ready. Multiple angles help the AI identify it better.
  • Know your rough price target or be ready to use comps inside ResaleOS.

Step 1: Start a new product

  1. Click the Products tab.
  2. Click Create product.

Step 2: Upload photos and let AI catalog your item

  1. Upload your item photos.
  2. ResaleOS AI will analyze the images and auto-fill as many fields as possible:
    • Title
    • Description
    • Category
    • Dimensions and weight (if it can infer them)

Tip: If the AI misses something, that’s normal. You can edit any field it fills in.

Step 3: Review and complete product details

  1. Title: Refine the AI title to be accurate and searchable. Example: “Oval Tulip Marble Dining Table.”
  2. Description: Keep it clear. Include material, color, style, any flaws, and what’s included.
  3. Category: Confirm it matches your item. Adjust if needed.
  4. Price:
    • If empty, use the pricing/comps panel to see how similar items are priced online.
    • Click any comp to open it and compare.
  5. SKU: Click to Generate an SKU, or enter your own format.
  6. Inventory by location: Enter quantity per warehouse (e.g., “2 in San Francisco,” “1 in New York”).
  7. Condition: Choose the best fit (e.g., Excellent). Add notes if helpful.
  8. Dimensions and weight: Verify what AI suggested. Correct if needed.
  9. Attributes: Add relevant details for the category (material, color, style, brand, era, etc.).

Tip: Accurate dimensions and weight help get the right shipping quotes with carriers (FedEx, GoShare, UShip) and reduce return risk.

Step 4: Choose where to post (sales channels)

  1. Select the channels you want to post to (e.g., Etsy, Pinterest, and any others you’ve connected).
  2. Optionally add channel-specific instructions, such as:
    • “Increase price by 10% on [Channel].”
    • “Append this line to the description on [Channel].”

Note: Marketplace rules vary. Only include content (like phone numbers or external links) where allowed by that marketplace.

Pro tip: You can set defaults for these instructions in Settings so they apply automatically every time you list.

Step 5: Add a consignor (optional)

  1. If this item is consigned, choose the Consignor from the dropdown.
  2. Adjust the consignment terms for this item if needed.
  3. If you don’t see the consignor, click to add them quickly from the side modal, then select them.

Step 6: Create the product and watch it post

  1. Click Create product.
  2. ResaleOS will begin posting to your selected channels.
  3. You’ll see posting progress and can open the live listing on each channel once it’s created.

Tip: Give each live listing a quick look. Make sure photos, price, shipping, and condition read correctly on every marketplace.

Practical tips

  • Photos: Use good light, neutral background, and capture any flaws honestly.
  • Titles: Front-load key terms buyers search for (brand, model, material, size).
  • Pricing: Start with comps, then adjust for condition, region, and shipping complexity.
  • Shipping: Large or heavy items benefit from accurate measurements for carrier quotes.
  • Consistency: Set your default channel rules in Settings to save time and keep pricing consistent across marketplaces.
