# CarParts.com Scales B2B Partnership from $45M to $50M Run Rate in 90 Days *Sequential quarterly growth shows how affiliate velocity compounds when logistics and merchandising align.* By **Jenny Huang Goodman MPA MSc MHSA, Principal** — The Stash Edge, Hako Shikin LLC.

Canonical: https://www.pops4.com/stash/articles/carpartscom-a-premium-2026-08-08t06-2 Subject: CarParts.com / A-Premium Tags: distribution, b2b partnerships, affiliate revenue, automotive parts, last-mile logistics --- CarParts.com moved its A-Premium partnership from a **$45 million** annualized run rate in Q1 2026 to nearly **$50 million** in Q2 2026, according to the company's quarterly disclosures cited by Seeking Alpha. The **$5 million** quarterly lift represents **11 percent** sequential growth in a single quarter, driven by last-mile package volume targeting **300,000 units** by year-end. The mechanism is straightforward: CarParts.com operates an e-commerce platform selling automotive parts directly to consumers and repair shops. A-Premium is a parts brand within the catalog. The partnership structure treats A-Premium as both supplier and affiliate, with CarParts.com handling merchandising, fulfillment, and customer acquisition while A-Premium manufactures and stocks inventory. Revenue scales as package count climbs, and the company stated it expects the arrangement to reach free cash flow positive by the end of 2026. What makes this work is the alignment of three distribution levers. First, CarParts.com already owns the last-mile infrastructure and customer demand, so adding A-Premium SKUs requires no new acquisition cost. Second, A-Premium benefits from CarParts.com's existing traffic without building its own storefront or ad stack. Third, both parties share margin risk: CarParts.com earns on fulfillment and merchandising fees, while A-Premium earns on wholesale volume without fronting retail overhead. The **11 percent** quarterly acceleration suggests the merchandising mix is improving or repeat purchase frequency is rising, both signs the partnership has found product-market fit within the existing customer base. The steal for a smaller physical-product brand is to identify a distributor or retailer already serving your target customer and propose a hybrid partnership that splits the value chain. You manufacture and stock, they merchandise and fulfill. The pitch is simple: they add margin without inventory risk, you add volume without acquisition cost. Start with a single SKU or category, set a **90-day** test window, and agree on transparent reporting so both sides can see unit velocity and margin contribution weekly. If the distributor already has logistics and traffic, your job is to ensure product availability and competitive landed cost. If they move **1,000 units** in month one, renegotiate terms and expand the SKU count in month two. Execution requires three operational commitments. First, you must maintain fill rates above **95 percent** or the partnership dies on backorder friction. Second, agree on a flat wholesale price that holds for the test period so the distributor can optimize merchandising without price volatility. Third, get weekly sell-through data in a shared dashboard so you can adjust inventory ahead of stockouts. The distributor will not promote a SKU that goes dark. For a one-person brand, this means either holding safety stock equal to **four weeks** of projected volume or negotiating a consignment arrangement where you ship to their warehouse on a **net-30** payment term. The trade-off is cash cycle risk for velocity certainty. The broader pattern is that B2B partnerships scale faster than owned-channel marketing when you align incentives and remove operational friction. CarParts.com and A-Premium grew **$5 million** in annualized revenue in **90 days** because neither party had to build new infrastructure. A small brand running the same play should expect **$10,000 to $50,000** in incremental monthly revenue within the first quarter if the distributor already has the customer file and the product fits existing purchase behavior. The next move is to land one partnership, prove the unit economics in **60 days**, then replicate the model with two more distributors in adjacent channels. ## The takeaway Partner with a distributor who already owns your customer, split the value chain, and scale on their infrastructure without acquisition cost. --- ## Publisher **Hako Shikin LLC** — Virginia Beach, Virginia.
