Parts Masters

Publishing approved marketplace listings, helping buyers search by real inventory clues, routing direct seller contact, and capturing wanted demand when inventory is missing.

  • A seller wants approved parts, trucks, trailers, or equipment discovered by buyers.
  • A buyer needs to search public listings or post a wanted request instead of checking out online.
Parts Masters is a lead-generation marketplace. Buyers confirm price, availability, condition, freight, payment, and fitment directly with sellers.Start seller intake

Surplix / eAgent

Listing research, source-labeled pricing decisions, repricing review, eBay inventory workflow support, and seller-controlled listing operations.

  • A seller already sells parts on eBay and needs better research, listing review, or repricing operations.
  • A seller needs source-labeled comp evidence before approving marketplace listing changes.
Surplix/eAgent is a separate listing-operations product. It does not make Parts Masters publish inventory, mutate eBay listings, or create buyer checkout on Parts Masters without a separate approved workflow.Ask about Surplix/eAgent

Shop Command

Service orders, technician time, parts workflow, invoicing readiness, customer history, and day-to-day shop operations.

  • A repair shop or fleet service team needs operational software, not a public marketplace listing.
  • A seller also runs a service department and needs better work-order, technician, parts, and invoicing workflow.
Shop Command is a separate shop-operations product. It is not a Parts Masters checkout, payment, escrow, freight, or seller-results system.Ask about Shop Command

No shared checkout, bundle promise, automatic integration, guaranteed leads, guaranteed sales, or guaranteed fitment is implied.

Parts seller with eBay inventory

The seller wants buyer leads from Parts Masters but also needs disciplined eBay listing research and repricing review.

Use Parts Masters for approved direct-contact marketplace listings and evaluate Surplix/eAgent for eBay listing operations.

Keep eBay mutations, Parts Masters publishing, and seller lead reporting separately approved and source-labeled.

Dealer with trucks or trailers

The dealer wants more searchable supply and buyer contact, but the inventory source, photos, and contact routing need review.

Use Parts Masters seller intake, source-rights review, manual import cleanup, wanted-demand routing, and seller reporting.

Do not present unapproved inventory as live, and do not show public seller pricing or results without real lead history.

Repair shop or fleet service team

The operator is less focused on public listings and more focused on work orders, technicians, parts, and invoicing readiness.

Use Shop Command for shop operations and Parts Masters only when the shop needs to find or list inventory.

Do not treat shop operations software as proof that Parts Masters can guarantee parts availability or buyer outcomes.

Claim boundaries

  • The products are not a bundled checkout or payment workflow.
  • Parts Masters does not guarantee fitment, availability, traffic, leads, sales, revenue, or seller results.
  • Surplix/eAgent and Shop Command are not implied live integrations with Parts Masters unless a named workflow is approved and proven.
  • Seller pricing stays manual quote only until real seller lead history supports stronger public claims.
  • No outbound email, SMS, CRM delivery, third-party mutation, production import, or listing publication is authorized by this resource page.

Recommended next step

Start with the inventory, seller contact path, source rights, and operations problem. Parts Masters should remain the direct-contact marketplace unless a separate Surplix/eAgent or Shop Command workflow is approved, configured, and validated.
