When supplement brands set up a trade partner portal, the most common gap is not missing technology — it is missing content. Partners log in and find incomplete product information, outdated images, or missing compliance documents. The portal exists, but it does not contain what distributors actually need.
This checklist covers the content and access features that distributors expect from a functional trade partner portal. Use it to audit what you have before going live, and to identify gaps that need filling.
Core product data
Every active product should have:
Product identifiers: Full product name, brand name, SKU codes (your internal code plus any trade or retailer-specific codes), EAN/barcode, and any case or pallet codes for wholesale ordering.
Ingredient and formula data: Full ingredient list in the correct labelling format for each market, allergen declarations, and any country-specific ingredient statements where relevant. This should match the physical label exactly.
Nutritional information: Complete nutritional panel per serving and per 100g where applicable. For supplement formats — capsules, tablets, powders — include both per-unit and per-serving data. Flag products with country-specific nutritional formats (EU versus US, for example).
Product specifications: Net weight, serving size, servings per container, physical dimensions, and case count. These are needed for logistics, listing builds, and trade ordering.
Product claims: Approved claims only. Do not include claims that have not cleared your regulatory process, even informally.
Digital assets
Every active product should have:
Packshots: High-resolution images on white background, minimum 2000px on the longest edge, in both JPEG and PNG. For products with multiple formats or sizes, a packshot for each variant. Retailers will not request the right variant if all they can see is a generic image.
In-use or lifestyle imagery: At least one image showing the product in context — in use, in environment, or with a consumption occasion. This is what goes into marketing materials and retailer category sections.
Label files: Print-ready label files for products with physical labels. Format requirements vary — check what your distributors need before assuming PDF is sufficient. Some will need editable formats for local market adaptation.
File naming convention: Consistent, predictable naming that distributors can use without renaming files. A format like ProductName_SKU_AssetType works. Inconsistent naming creates confusion and downloads of the wrong file.
Regulatory and compliance documents
The compliance document requirements vary by market and channel. For supplement brands operating across multiple markets:
Certificates of analysis: Current CoA for each product batch in active distribution. Should include testing date, lab name, and tested parameters. Out-of-date CoAs are one of the most common causes of listing rejection and retailer compliance queries.
Third-party certifications: Informed Sport, NSF Certified for Sport, or similar certifications where held. Increasingly required by sport and fitness retailers and expected by distributors in those channels.
Country-specific compliance letters: Regulatory filings, notification letters, or compliance statements for each market where the product is sold. The EU, UK, Australia, and Canada each have distinct requirements. These should be market-specific, not generic.
Allergen documentation: Full allergen matrix for the product range, and any safety data relevant to ingredient sourcing or manufacturing. Required by many food and supplement retailers as part of supplier compliance.
Commercial and pricing information
Trade pricing and minimum order quantities: This should be gated to partners who are actively trading with you — not visible to all portal users. Access controls matter here.
Lead times and availability: Current lead times by product and market, updated regularly. Stale lead time information creates ordering problems downstream and erodes distributor confidence in your data.
Promotional terms: Where you run promotional pricing or terms for specific partners, a portal can be the channel for communicating this in a controlled, documented way rather than over email where terms get lost.
Sales support and training materials
Product education: Category guides, ingredient explainers, product comparison tools, and materials that help distributor sales teams understand and explain the range. This content is often what separates brands that distributors actively sell from brands that just sit on a list.
Retailer pitch materials: Range presentations, category rationale, and any materials designed to support ranging conversations with new retail accounts. Distributors who can present your brand confidently will open more doors.
Merchandising guides: Where relevant, visual merchandising guides, planogram suggestions, and display materials for in-store retail partners.
Access and notification features
Content alone is not enough. The portal access model matters as much as what is in it:
Segmented access: Different partner types should see different content. A regional distributor focused on sports nutrition should not see your full range if they only carry a subset. Showing irrelevant content reduces the signal-to-noise ratio for the content they do need.
Version control: When an asset is updated, the previous version should be replaced — not added alongside it. Distributors should not be able to download a superseded file by mistake. This is where most email-and-Dropbox setups fail: old files persist indefinitely.
Notifications: Distributors should receive alerts when content relevant to them changes. Not a weekly newsletter — specific alerts tied to specific products they are active on. A notification about a label change should link directly to the updated file, not to a general portal page.
Visibility: You should be able to see which partners have accessed which content. This tells you who is engaged and what they are using — without having to ask. Visibility also tells you when a partner has not accessed a product launch, which is a signal worth following up on.
What this checklist tells you
If you work through this list and find gaps — products with no packshot, missing CoAs, outdated regulatory documents, no consistent file naming — the portal is not the problem. The portal makes those gaps visible. The work is filling them.
This is not a reason to delay going live. A portal with eighty percent of the content your distributors need is significantly better than the status quo of email and request-based sharing. But it does mean being transparent with partners about what is coming and when, rather than presenting an incomplete portal as finished.
Stackcess surfaces what is missing. For products without images, documents, or complete data, the gaps appear in the platform before partners encounter them — so you can close them on your timeline, not discover them when a distributor flags a problem.
