Everything New in BigSeller: May 2026 Recap

Every month, the BigSeller team sets out to make life a little easier for sellers across Southeast Asia. In May, we did not hold back. Several new features landed across inventory, fulfillment, finance, purchasing, marketing, and AI. Some were quietly powerful, others were long overdue. Here is our honest recap of what shipped and why it matters to your store.

A smarter way to manage what you buy

One of the biggest changes this month touches something every seller deals with daily: procurement. The old Purchase Order flow forced you to assign an entire order to one supplier and one warehouse. If your products come from multiple vendors, that means extra manual work every single time.

The new Purchase Plan feature fixes this by letting you manage stock requests SKU by SKU rather than order by order. You consolidate everything into one plan, send it for team review and approval, and then split it into individual purchase orders by supplier and warehouse in a single click. Combination SKUs are automatically broken into their sub-components too. It is a more realistic match for how most sellers actually source their products.

Your inventory now knows the difference between good and damaged stock

If you have ever accidentally shipped a damaged return to a customer, you know how painful that is to fix. This month we introduced a dedicated Defective Shelf type inside BigSeller warehouses. Sellable and unsellable stock now live in strictly separate buckets. Damaged goods, failed quality inspections, and returned items no longer share space with your good inventory. It is the kind of structural change that prevents costly mistakes quietly and consistently.

Alongside this, we launched Serial Number (SN) Management for sellers handling high-value or electronic products. Every unit now carries a traceable ID from the moment it enters your warehouse all the way through to delivery and potential return. This closes the door on fraudulent returns and inventory mismatches.

Finance reporting that actually fits your business

Rigid expense categories have always been a poor fit for the reality of running an e-commerce store. In May, we upgraded the Profit Report module to support fully custom expense types. You can now define your own categories and set flexible allocation rules that account for differences in store size and product pricing. A new Fee Allocation Records page gives you complete visibility into where every ringgit is going.

AI tools for product visuals and listings

Creating strong product images and well-written listings has always been time-consuming, especially when selling across multiple markets and languages. This month we launched AI Image Designer and AI Copywriter to take that weight off your plate.

The image tool transforms raw product photos into commercial-grade visuals. You can generate white background catalog shots, lifestyle photos, and promotional posters, and use built-in tools for object removal and image expansion. The copywriter handles titles and descriptions built for Southeast Asian platforms, with keyword embedding and restricted word screening to keep your listings safe and visible. Both tools are available now inside BigSeller.

Temu sellers now have 3PL logistics support

Temu fulfillment got a meaningful upgrade this month. You can now select third-party logistics providers for Temu orders, with support for J&T, GHN Express, Flash Express, and more across the region. One thing to be aware of: Temu's privacy compliance requires you to re-authorise address decryption permission in the Temu Seller Center every seven days. After doing that, re-authorise your Temu store inside BigSeller as well to keep data syncing smoothly.

Get notified when your ads need attention

Ad performance can shift overnight, and no one has time to manually check every campaign every day. The new Automatic Ad Alert Rules feature lets you set your own conditions, whether that is a drop in ROI, a ROAS threshold, or any other metric you track. When an ad triggers your rule, you get notified automatically through WhatsApp, Viber, Telegram, Facebook, or email.

Flag bad orders before they ship

Two new features help you catch problem orders before they leave the warehouse. Duplicate Order detection marks repeat purchases for review. Risk Buyer Management flags customers with a history of high return rates and gives you the option to hold their orders or add them to a blacklist. Both features work on newly synced orders only and require you to configure rules before activating. They are available on the Basic plan and above.

Everything else that shipped

Beyond that, May also brought a handful of solid additions worth knowing about.

The Pick List feature now includes a label-style template made for label printers. After picking an order, you stick the label directly onto the parcel, which cuts down on packing mix-ups and paper waste. It supports standard label sizes from 40x30 mm to 70x30 mm with QR code scanning built in. It works best for single-SKU orders.

The new Business Analysis Report gives operations and management teams a single view of store performance across sales, revenue, profit, cancellations, refunds, ad spend, and inventory. It currently covers Shopee, TikTok, and Lazada with data refreshing on a T+1 basis.

POS users in Malaysia now have access to the official 5-sen cash rounding standard. Other markets can configure truncate or half-up rounding to match their local requirements.

Two-way inventory sync between Accurate and BigSeller is now live. Accurate's stock counts update BigSeller in real time, with FIFO rules applied to decreases and every change automatically logged.

A big thank you

We also wrapped the BigSeller E-Commerce Summit 2026 in Malaysia this month. Thank you to every seller, partner, and team member who came out and made it such a memorable event.

We will keep shipping. Follow along on the BigSeller changelog and let us know what you would like to see next.
