Something is happening inside Amazon’s Supply Chain by Amazon division, and the 3PL industry is starting to notice. Multiple sources close to the matter — including two agency operators who work directly with mid-market DTC brands — say Amazon has been conducting private outreach to Shopify merchants doing between $5M and $50M in annual revenue, pitching a fulfillment arrangement that would let them store and ship non-Amazon inventory through Amazon’s warehouse network without any FBA listing requirement.
The product, reportedly being trialed under the internal codename “Project Offsite,” would give Shopify brands access to Amazon’s same-day and two-day delivery infrastructure at rates that sources describe as “aggressively below” what ShipBob and Flexport are currently quoting for comparable SLAs. One agency founder who asked not to be named said a client received an outreach email from an Amazon Business Development rep in April offering a rate card that showed fulfillment costs approximately 18 to 22 percent lower than their current ShipBob contract.
“If the numbers we’re seeing in these pilots are real at scale, Amazon is essentially trying to make third-party fulfillment a loss-leader to capture Shopify’s merchant base,” said one supply chain consultant who advises several nine-figure DTC brands and asked to remain anonymous. “That’s a very Amazon move.”
What Exactly Is Amazon Allegedly Offering Shopify Merchants?
According to sources, the outreach is not a simple expansion of the existing Multi-Channel Fulfillment program, which has been available for years but has historically suffered from slower delivery windows and a stigma around Amazon-branded packaging. This new arrangement reportedly addresses both friction points directly. Unconfirmed details circulating among 3PL operators include:
- Delivery SLAs of two days or less for roughly 80 percent of the continental U.S., matching Amazon Prime speeds
- White-label or neutral packaging options with no Amazon branding, reportedly a hard requirement from participating brands during the pilot
- Shopify-native integration that would surface fulfillment options directly inside Shopify admin, similar to how Shopify Fulfillment Network operates
- Per-unit rates in the $3.20 to $4.80 range depending on unit weight and dimensions, undercutting what industry sources say is a $4.50 to $6.50 range at comparable mid-market 3PLs
- A revenue-share or data-access clause buried in the terms that sources say has not been fully disclosed to pilot participants
That last point is where things get complicated. A contracts attorney who reviewed a redacted version of the alleged pilot agreement — shared with Ecommerce Times by a source who declined to be identified — said the data provisions were “unusually broad” and would give Amazon visibility into Shopify-side sales velocity, SKU-level demand patterns, and customer zip code distribution. “That’s not fulfillment data. That’s competitive intelligence,” the attorney said.
How Are ShipBob and Flexport Responding Internally?
Neither ShipBob nor Flexport responded to requests for comment by publication time. But sources close to both companies paint a picture of genuine concern. At ShipBob, according to one person familiar with internal discussions, leadership held an emergency account retention review in late May after three mid-market clients flagged that they were in conversations with Amazon about alternative fulfillment. The review allegedly resulted in a directive to the sales team to offer proactive rate concessions of up to 15 percent for any account with an annual contract value above $180,000.
“ShipBob’s retention team is now calling clients they haven’t spoken to in six months,” said one Shopify agency operator based in Austin. “That doesn’t happen unless something scared them.”
At Flexport, the situation is reportedly more complicated. Sources say the company’s fulfillment division — which has struggled to fully integrate the legacy Deliverr infrastructure acquired in 2022 — views Amazon’s move as particularly threatening because Flexport has been trying to pitch the same mid-market Shopify segment as its growth vector for 2026. One Flexport mid-market account executive reportedly told a prospect in May that any Amazon fulfillment offer would “come with strings you can’t see yet,” though it’s unclear whether that framing was scripted or off-the-cuff.
Is Shopify Aware of Amazon’s Merchant Outreach?
This is the question several agency owners are asking loudly in private Slack channels. The relationship between Shopify and Amazon has always been a studied détente — the two companies compete for merchant mindshare but have historically avoided direct infrastructure conflict. If Amazon is actively recruiting Shopify merchants into a fulfillment ecosystem with deep data-access terms, that would represent a meaningful escalation.
Shopify declined to comment officially. But sources familiar with Shopify’s partnerships team say there have been “heated internal conversations” about whether the alleged Amazon pilot violates the spirit of the data-sharing boundaries established under Shopify’s Buy with Prime integration rollout. Harley Finkelstein, Shopify’s President, has not commented publicly, but sources say he was briefed on the Amazon outreach reports in late May.
“Shopify’s whole pitch to merchants is that they own their data and their customer relationships. If Amazon can access SKU velocity and demand signals through a fulfillment backdoor, that’s a direct threat to the trust architecture Shopify has spent a decade building,” said one DTC brand founder who sits on a Shopify merchant advisory panel and asked not to be named.
Which Merchant Segments Are Most at Risk of Defecting to Amazon Fulfillment?
Sources suggest Amazon’s outreach has been most effective with merchants in three specific categories: high-volume consumables, personal care, and home goods — categories where unit economics are tight and where a 20 percent reduction in fulfillment cost meaningfully moves contribution margin. Brands in these categories typically ship high volumes of small, lightweight SKUs, which is where Amazon’s warehouse density creates the most structural cost advantage.
Merchants in furniture, large-format goods, and cold chain categories are reportedly not part of the pilot, likely because Amazon’s infrastructure advantages diminish at higher dimensions and weights. Several apparel brands were also allegedly approached but declined, citing concerns about return processing quality — an area where sources say Amazon’s MCF product has historically underperformed dedicated 3PLs.
- Categories reportedly included in pilot: supplements, skincare, haircare, household cleaning, small electronics accessories, pet consumables
- Categories reportedly excluded: furniture, oversized goods, apparel requiring quality inspection, perishables
- Merchant revenue range targeted: $5M to $50M annual Shopify GMV
- Geographic focus: brands with high order density in top 15 U.S. metro areas, where Amazon’s fulfillment center footprint is densest
What Does This Mean for the Broader 3PL Market in H2 2026?
If even a fraction of the pilot terms described by sources are accurate, the implications for mid-market 3PLs are significant. The segment between $5M and $50M in annual revenue has historically been the sweet spot for companies like ShipBob, Whiplash, and Ware2Go — large enough to justify dedicated account management, but not large enough to negotiate the enterprise contracts that insulate nine-figure brands. Amazon targeting exactly this tier is, in the words of one 3PL operator, “going after the belly of the market.”
Broader market observers note that this move, if real, fits a pattern Amazon has executed in other verticals: offer a service below cost to established players, use the data and volume to optimize the product, then raise prices once the competitive alternatives have been weakened. It is an unconfirmed strategy in this context, but the concern is widespread enough that several 3PL operators told Ecommerce Times they are now actively modeling scenarios in which Amazon captures 10 to 15 percent of the mid-market fulfillment segment within 18 months.
“The 3PL industry has been warning about Amazon doing this for five years. The question was always timing and packaging. If the white-label option is real, the packaging problem is solved,” said a supply chain analyst at a firm that tracks fulfillment market share and asked not to be identified ahead of a report they are preparing for publication later this month.
For Shopify and Amazon sellers reading the tea leaves: the next 90 days will be telling. If Project Offsite or whatever Amazon is actually calling this program moves from private outreach to a formal announcement, it will force a renegotiation across the entire mid-market 3PL landscape. Rate cards will compress, SLA commitments will sharpen, and the data-access fine print in every fulfillment contract will suddenly deserve a lot more attention from merchant legal teams. Ecommerce Times will continue reporting as more details emerge.
