Parts sell on marketplaces the moment the fitment data is right and stop selling the moment it is not — and none of those buyers are yours to keep unless you plan for it.
Delivered remotely for brands across Detroit and Michigan.
Detroit is one of the few markets where the marketplace question has a genuinely different answer for every catalogue on the street. A performance or restoration brand belongs on Amazon and, unusually, on eBay Motors, where parts buyers have been searching by vehicle and part number for two decades and the category never migrated away. A tooling or MRO supplier has a real Amazon Business audience with quantity pricing and tax exemption behaviour that consumer sellers never see. A heritage workwear label sells nationally on Amazon and on video. A machine shop selling engineered components to a purchasing department belongs on none of them, and we will say so.
Wherever it does apply, the data comes before the advertising. Vehicle applications and interchange numbers submitted in the format the marketplace catalogue expects, so compatibility is confirmed on the listing rather than guessed at checkout. Parentage built so sizes and finishes pool their reviews. Backend search terms carrying the OEM numbers, supersessions and misspellings buyers actually type without stuffing them into the title. Get this wrong in a parts catalogue and the damage arrives as returns and one-star reviews, which cost far more to unwind than they did to prevent.
Then the strategic part, which is why we do this alongside the Shopify build rather than instead of it. A marketplace order gives you a sale and a platform's customer. Your own store gives you the fitment history, the build list, the reorder and the email address. So we use the marketplace for the SKUs that win on search and price comparison, keep kits, bundles and anything that needs a real fitment tool on your own site, and use package inserts, warranty registration and the brand tools the platform actually permits to give a first-time buyer a legitimate reason to come to you next time.
Two operational realities shape a Detroit marketplace account. The first is that demand here is violently seasonal in a way that collides with how fulfilment networks charge. Rust repair, undercoating, batteries and cold-weather replacement parts sell hard from November through March; performance and restoration sells into the spring and summer build season and peaks around the August show circuit on Woodward. Stock sent into a fulfilment centre for the wrong half of that calendar sits through months of storage charges and aged-inventory surcharges, quietly turning a profitable SKU into a loss. We plan replenishment against your two demand curves and pull slow stock before the charges land rather than after. The second is the border. Detroit–Windsor is the busiest commercial freight crossing on the US–Canada frontier, and a Michigan brand is often one decision away from selling into Amazon.ca on a unified North American account — genuinely worthwhile for consumables and universal-fit product, and genuinely painful for anything where customs classification, duty and country-of-origin marking on automotive goods have not been thought through first. We check that the paperwork works before the listings go live, not after a shipment is held.
The same standard of work we run for every client — applied to a Detroit brand’s realities.
Full service detailTitles, bullets, backend search terms, variation parentage and category nodes rebuilt across Amazon Seller or Vendor Central, TikTok Shop and Walmart. Suppressions and stranded inventory fixed at the cause, not resubmitted.
Brand Registry enrolment, A+ and Premium A+ modules, Brand Story and Storefront pages built to each platform's image and copy specs. Produced inside this service because the formats are fixed.
Campaigns split by intent and margin band, converting search terms promoted to exact, negatives maintained weekly, and targets set from contribution margin instead of a category average.
FBA against FBM modelled per SKU on size tier, storage, return rate and reimbursement recovery. Some products should never enter a fulfilment centre, and we name which of yours.
Catalogue sync, listing compliance, sample seeding to affiliates, and live and video commerce, run as a mechanic of this channel rather than as a separate affiliate programme.
SKU allocation, MAP and pricing alignment, marketplace-only bundles and pack sizes, plus the permitted paths home: package inserts, Brand Registry tools and platform-allowed follow-up.
We do not work off a rate card. Every Detroit engagement starts with a fixed statement of work — named deliverables, named dates, one number — written after we have looked at your store, not before. If a smaller first step would serve you better, we will say so.
Get this scopedListing quality, suppressions, buy-box history, variation structure, the fee and returns reports and ninety days of search terms. You get the findings whether you hire us or not.
Parentage, titles, backend terms, imagery and A+ rebuilt before any spend moves. Advertising a listing that converts badly buys traffic for whoever else is in the carousel.
Which SKUs sell where, at what price, in what pack size, agreed with you in writing. The marketplace should not be bidding against your own store for the same order.
Sponsored campaigns rebuilt by intent and margin band, with ACoS and TACoS targets derived from contribution per unit after referral, fulfilment and return costs.
Weekly search-term mining, monthly fee and reimbursement review, and the insert and registry mechanics that give a marketplace buyer a reason to reorder on your site.
Thirty minutes with the strategist who would actually run your account. We screen-share your store, read your data live, and tell you the three highest-value things we can see from the outside.
