How to add a new product to your catalog
Overview
Adding products to your Seamline catalog is the first step in managing your custom apparel offerings. Each product can include variants, pricing tiers, and images that your customers will see when browsing your store or receiving a quote.
Adding a new product
Follow these steps to create a product:
- Navigate to the Products page from the left sidebar.
- Click the "Add Product" button in the top-right corner.
- Enter the product name, description, and select a category (e.g., T-Shirts, Polos, Jackets).
- Upload at least one product image — this will be the primary thumbnail.
- Set the base price and any applicable bulk pricing tiers.
- Click "Save Product" to publish it to your catalog.
You can save a product as a draft if you are not ready to make it visible to customers yet. Drafts will not appear in quotes or team stores.
Managing product variants (sizes, colors)
What are variants?
Variants represent the different options a product is available in — typically sizes and colors. Each unique combination (e.g., Large / Navy) is tracked as its own variant with independent inventory and optional pricing overrides.
Creating variants
To add variants to a product:
- Open the product you want to edit from the Products page.
- Scroll to the Variants section and click "Manage Variants".
- Add size options (e.g., XS, S, M, L, XL, 2XL) by selecting from the predefined list or entering custom sizes.
- Add color options with a name and hex code so they display correctly in your store.
- Review the generated variant grid — Seamline automatically creates every combination.
- Optionally adjust pricing or SKU for individual variants.
If a specific size/color combination is not available, you can disable it in the variant grid without deleting the entire size or color option.
Setting up product pricing and bulk pricing tiers
Base pricing
Every product requires a base price, which is the per-unit cost at the default quantity. This price appears on quotes, team stores, and order summaries unless overridden by a bulk tier.
Setting up bulk pricing tiers
To configure volume discounts:
- Open the product and navigate to the Pricing tab.
- Enter the base price in the "Unit Price" field.
- Under "Bulk Pricing Tiers", click "Add Tier".
- Enter the minimum quantity and the discounted per-unit price for that tier (e.g., 25+ units at $18.00 each).
- Add as many tiers as needed — they will apply automatically when a customer meets the threshold.
- Click "Save" to apply changes.
Bulk pricing tiers are shown to customers in a pricing table on quotes and team store pages, which encourages larger orders.
Uploading and managing product images
Image requirements
Product images are displayed across quotes, team stores, and order confirmations. For best results, use high-resolution images (at least 1000x1000 pixels) with a clean background. Supported formats are JPG, PNG, and WebP.
Uploading images
To add images to a product:
- Open the product from your catalog.
- Click the "Images" tab or scroll to the image gallery section.
- Click "Upload Image" or drag and drop files into the upload area.
- Reorder images by dragging them — the first image becomes the primary thumbnail.
- Click "Save" to confirm the changes.
Uploading mockups with your customer's logo applied can significantly increase conversion on quotes and team store pages.
Tracking product inventory
How inventory tracking works
Seamline tracks inventory at the variant level. When an order is placed, the corresponding variant quantities are automatically decremented. You can also enable low-stock alerts to be notified when inventory drops below a threshold.
Setting up inventory tracking
To enable and configure inventory:
- Open the product and go to the Inventory tab.
- Toggle "Track Inventory" on for the product.
- Enter the current stock quantity for each variant.
- Set a "Low Stock Threshold" — you will receive a notification when inventory reaches this number.
- Click "Save" to begin tracking.
If you use Shopify integration, inventory syncs automatically between platforms. You do not need to update stock manually in both places.
