Will it list, and will it sell? Know before you send it.
Syndic8's Preflight has each sales channel's acceptance rules and content guidelines built in. It runs your products through them before anything goes out, and gives every product three scores: Listing Readiness (will Amazon or Walmart accept it), Channel Optimization (will it win the buy box and show up when shoppers search) and Asset Readiness (will the images pass). The submit, wait, get rejected, fix, resubmit loop goes away.
Submit, wait, get rejected, fix, resubmit. Then find out the product listed three weeks late.
Every channel has acceptance criteria and a content guideline. Meeting them used to mean mapping your data to the channel's template by hand, guessing if it would bounce, submitting, waiting, and reading the rejection report. Each loop costs days or weeks, and a product that lists late is a product that isn't selling. Major marketplaces also score suppliers on the quality of what they send, so a sloppy submission can cost more than one listing.
The channel's rules are built in
Syndic8 sources and packages templates, valid-value lists, and PDP content guidelines straight from major marketplace APIs. You never have to read a 134-page refrigerator guideline to find out what you missed.
A dry run of the real export
Preflight transforms your products exactly as the export would, then stops. You see what the channel would see, within your own four walls, before your relationship with the retailer is on the line.
Failures are the to-do list
Zoom in on what failed and only that. The failing fields are listed per product with the rule behind each one, and the same results feed Data Remediation so the fix starts where the problem is.
Readiness is the bare minimum. Optimization is what sells. Assets are where most listings quietly fail.
Each score runs 0 to 100, per product and for the whole collection, per channel. The same product can be 95 for Walmart and 60 for Amazon, because each channel wants different fields, formats and content.
Will it list?
Required fields filled. Values drawn from the channel's pick list where one exists. Formats the channel accepts. The classic rejection: your marketing color is Champagne Bronze, and Amazon's color pick list doesn't have it. The AI matches it to the closest accepted value so the listing goes through. Country of origin, now required almost everywhere, is the other one that trips people up.
Will it sell?
Titles, bullets, descriptions, search terms and attributes graded against the channel's own PDP guideline for that product category: the rules that decide the buy box, the supplier score and where you land in search. A product whose short and long descriptions are identical passes readiness and fails here. So does a bullet that uses the same word three times, or bullets in the wrong order. No regex can check those. Only a person or an AI can.
Will the images pass?
Is there an image in every slot the channel requires, in a format it accepts, at the size it wants, and does the first one meet the main-image rule (product on pure white, filling at least 85% of the frame on Amazon)? You get a preview of how the images will render at the channel, per SKU, with the gaps named. How image matching, tags and preflight work.
Hundreds of pages of retailer rules, applied to every product you sell, without anyone having to read them.
A marketplace content guideline is long, specific and written for one product category at a time. Walmart's tire standard runs 43 pages. Amazon's refrigerator guidance runs 134. They are impossible for a person to follow consistently across thousands of SKUs and prime for a computer to automate, except that most of the rules can't be reduced to a pattern match. That's where AI changes everything - Syndic8's AI reads each guideline and turns it into a scoring rule set per channel, per category. When the guideline changes, the scoring changes with it. A sample of what's in there:
Which feature matters most, and whether a phrase is promotional, is judgment. No pattern match makes that call.
Rebuilding a title means knowing which word is the key attribute and which is the style. That is reading, not matching.
A tire title is built from six fields, and the category rule overrides the general one. Scoring applies the one that wins.
Twenty-four formulas inside one category. Scoring knows which one applies to the SKU in front of it.
The haul-away sentence is the single most common violation in the category, in a bullet that is otherwise fine.
Syndic8 scores these and flags them. It never writes them for you.
Rules stack in layers: the channel's general guideline, and a hierarchy of product-type guidelines that win where the two disagree. Your own brand standards can be added as a layer and scored the same way.
Score it, fix what blocks listing, optimize what sells, then send.
Run preflight on a collection for a channel
From the Preflight screen, by typing /preflight in Syndic8 Copilot, or by asking Claude, ChatGPT or Copilot through the MCP server. Set collections up per product type per channel, because the templates and guidelines differ. You get the three scores for the collection, each product's scores, and the failing fields with the rule behind each one.
Fix what blocks listing with Data Remediation
Readiness failures become a repair queue, one row per blocking field, biggest first. The AI reverse-engineers missing values from the rest of the product (fluid ounces on the bottle means the item form is liquid; the brand is sitting in the style name), matches rejected values to the channel's pick list, and shows its reasoning. You accept, reject or edit, apply, and rerun preflight. Prices are never remediated; a price is literal. How remediation works.
Optimize what sells with Channel Optimization
For the fields that pass readiness but score low, Syndic8's AI rewrites titles, bullets, descriptions and search terms to that channel's guideline for that category and saves them as channel-specific versions. Your core content is untouched; Walmart gets a Walmart version, Amazon an Amazon one. How channel optimization works.
Send it, or hand the gaps to the right people
Export in the channel's own format, including Amazon's macro-driven spreadsheet with required-but-missing cells in red, or through the API connection. Or ask your assistant to run preflight weekly and split the gaps by owner: copy gaps to marketing, image gaps to the DAM team, pricing gaps to finance, each with their own spreadsheet.
What a score does and doesn't promise.
Scoring never changes your data.
Preflight is read-only. Fixes come through remediation and optimization, and each one is approved by a person before it lands.
It measures against the channel's rules, not ours.
The checks come from the retailer's own guideline. Where a retailer publishes no field weights, Syndic8 weights the pillars, and you can see how.
A high score means the measurable checks pass.
Rules that need a person's judgment are listed for manual review rather than scored. A score is not a certificate of compliance, and no one can promise a buy box.
It's per channel, per product type.
Compare two channels' templates side by side to see what one wants that the other doesn't, before you decide what to fix first.
Free scoring of your catalog. Send a product file and name the channel.
We'll run preflight against that channel and send back the three scores, the failing fields, and the rules behind them. Nothing to install, nothing written to your data, and you'll know exactly what the channel would have rejected.
