Channels Update — September 2026

Published 3 September 2026. September is the moment to turn peak-season plans into stock that can actually be sold. This month, the useful changes are close to the warehouse floor: inbound deadlines, international dispatch, product identification, listing photographs and reliable availability updates.

Here is our latest briefing for Amazon, eBay, Shopify, WooCommerce, Discogs and Web, checked against official sources on 3 September. It covers new releases and earlier announcements whose deadlines or rollouts now matter. UK-specific dates are labelled; the operational recommendations are ours, not additional platform requirements.

Executive summary

• Amazon: work backwards from peak-season arrival dates, not the day you intend to dispatch stock.
• eBay: confirm your account’s international shipping programme before changing dispatch or returns procedures.
• Shopify: check the post-Stocky workflow and test the new support for multiple barcodes per variant.
• WooCommerce: review the new withdrawal-request workflow separately from refunds and returned stock.
• Discogs: use item-specific listing photographs to show the physical copy the buyer will receive.
• Web: investigate old Google feed integrations now; an occasional successful update is not proof of a healthy service.

Amazon

What changed

Amazon’s published UK peak calendar sets FBA inventory arrival targets of 16 September for Prime Big Deal Days and 28 October for Black Friday Week. These are arrival dates at Amazon’s facilities, not dispatch dates. Deal submissions close on 23 September and 18 November respectively; eligible Black Friday Week submissions by 5 September receive a 30% discount on the upfront promotion fee.

A festive peak fulfilment fee also applies to selected UK and German FBA orders from 15 October 2026 to 14 January 2027. Check the applicable product and fulfilment category rather than applying an average fee to every SKU. Source: Amazon’s official peak-season notice.

Inventory and selling impact

A promotion is only useful if the stock arrives and the margin survives. Our recommendation is to approve replenishment and promotional pricing together, rather than treating them as separate decisions.

What to do now

1. For each promoted SKU, assign an arrival date, quantity and owner; flag shipments with no receiving buffer.
2. Recalculate contribution after advertising, fulfilment and expected returns before accepting a discount.
3. Protect the stock needed by your other Channels instead of sending the entire shared balance to FBA.

eBay

What changed

September’s seller news highlights eBay International Shipping (eIS), replacing the Global Shipping Programme. Eligible UK sellers are being enrolled in phases from August; eBay emails the account when it moves. The domestic hand-off remains a UK hub, while eBay manages the international leg. International selling fees are waived on eIS purchases, and the programme advertises payout protection after the hub scan, subject to its terms. Source: September seller news. Programme details and eligibility.

Inventory and selling impact

This is an account-specific rollout, not a reason to relabel every international order. Our operational priority is to keep the shipping programme, tracking evidence and stock disposition clear throughout the order’s life.

What to do now

1. Check the enrolment message and actual order details; continue your existing process until your account moves.
2. Keep domestic tracking and hub acceptance evidence. A hub scan is not the same event as delivery to the buyer.
3. Review eIS case handling before issuing a duplicate refund, and never restore returned units to sellable stock unless they have physically come back and passed inspection.

Shopify

What changed

Stocky has closed for inventory operations. Shopify’s current migration guide says the app and its APIs stopped operating on 31 August 2026. Read-only access remains for at least 90 days to export records. Historical purchase orders and stocktakes do not automatically move into Shopify, and suppliers cannot be exported from Stocky.

Multiple-barcode lookup arrived on 1 September. Shopify POS v11.14 can identify a variant using any barcode already associated with it in Shopify Admin. This helps where suppliers or packaging use different identifiers for the same variant. Source: Shopify’s barcode announcement.

Inventory and selling impact

For former Stocky users, the immediate risk is an incomplete handover: a delivery received in one process but missing from another. Barcode convenience also depends on correct mappings; an extra identifier should not accidentally create an extra product.

What to do now

1. Confirm where staff now create purchase orders, receive deliveries, transfer units and perform counts. Check any integration that previously called Stocky.
2. Export the history you need while access remains, and reconcile open deliveries against physical receipts before entering them again.
3. On a supported POS version, test alternate barcodes against several variants and pack sizes. Confirm each resolves to the intended item and quantity.

WooCommerce

What changed

WooCommerce 11.1 was announced on 3 September. Variation image galleries are now included in core, replacing the separate Additional Variation Images extension. The release also adds an optional order-withdrawal form, disabled by default. Requests notify the merchant; they do not automatically cancel the order, change its status or issue a refund. Source: WooCommerce’s 11.1 release announcement.

Inventory and selling impact

A customer request, a refund and a physical return are different events. Our recommendation is to give withdrawal requests an owner, while keeping stock decisions tied to the actual fulfilment and return position.

What to do now

1. Test the update with your theme and extensions before changing the live shop.
2. If you enable Order Withdrawal, verify the customer form and notifications, and agree who checks outstanding requests.
3. Do not restock a dispatched item simply because a request arrived. Inspect returned goods before offering them again.
4. Check that each variation’s gallery shows the correct colour, size or version.

Discogs

What changed

Discogs’ item-photo guidance dated 21 August explains how sellers can add, reorder and remove photographs on individual Marketplace listings through its mobile app. Saved photographs are visible to buyers when the listing is For Sale. This is recently published guidance; its date is not evidence that the feature first launched that day. Source: Discogs’ item-photo guide.

Inventory and selling impact

For used records, the release identifies the edition; the condition belongs to the particular physical copy. Our recommendation is to use photographs alongside accurate grading and notes, especially where copies differ.

What to do now

1. Prioritise valuable items and copies with visible sleeve wear, missing inserts or distinguishing details.
2. Photograph the actual copy and keep its local SKU with the files so images are not attached to another copy of the same release.
3. Check the saved listing from the buyer’s view after uploading in Discogs.

This is a workflow in the Discogs app, not automatic photo publishing from ChannelWeave. Our Discogs tools remain manual/file-based rather than a live Marketplace synchronisation connection.

Web commerce

What changed

A clarification to our August issue: Google’s Content API for Shopping reached its sunset on 18 August, but that was not a universal immediate switch-off. Google’s timetable, updated on 1 September, now describes intermittent HTTP 410 Gone failures for clients without an active extension. Full decommissioning is planned for early 2027, with timing subject to revision. Custom integrations need to move to Merchant API; ecommerce platform providers manage migration for merchants using their services. Source: Google’s current sunset timetable.

Inventory and selling impact

Our concern is stale offers: the shop sells its last unit, but the advertising feed still presents it as available. A job reporting some successful requests can conceal individual products that were never updated.

What to do now

1. Identify who owns the feed. For a custom integration, inspect failed requests and finish the migration rather than relying on retries.
2. For a platform-managed feed, check provider status and Merchant Center issues instead of commissioning an unnecessary replacement.
3. Sample recently sold-out products and price changes: compare the current feed with the product page and checkout.

Cross-channel operator checklist

Give these checks an owner and a date this week:

• Stock: reconcile physical units, commitments and quantities offered across Channels.
• Buying: separate proven replenishment from speculative peak-season purchases.
• Dispatch: record the actual hand-off and preserve tracking evidence.
• Returns: distinguish a financial resolution from goods received and ready to resell.
• Data: investigate stale availability and ambiguous barcode mappings before increasing traffic.

The aim is not more administration. It is fewer surprises between buying stock, making the sale and keeping the promise to the customer.

Sources and scope

The official sources are linked beside each update. Information was checked on 3 September 2026; later changes are outside this issue. Confirm account eligibility and current platform terms before acting. These are seller-operating recommendations, not announcements of new ChannelWeave integration capabilities.
