Quick Answer: BigSeller is a free all-in-one ERP for Shopee, Lazada, and TikTok Shop sellers in SEA. This BigSeller review for Shopee and Lazada sellers gives it 4.5 out of 5 — it centralises your listings, orders, and inventory across all three platforms in one dashboard, includes an AI listing generator, and is genuinely free for most sellers. Best for multi-platform stores doing 50+ orders per month.
If you’re selling on Shopee, Lazada, and TikTok Shop at the same time, you know the chaos: three separate dashboards, three sets of orders to track, three inventories that can go out of sync. Oversell on one platform and you’re dealing with cancellations, penalty points, and a damaged seller rating. That’s the problem BigSeller was built to solve.
This BigSeller review for Shopee and Lazada sellers covers what it actually does, which features matter most for SEA marketplace sellers, what “free” really means, and where it falls short. If you’re managing multiple stores or platforms, read this before signing up for anything else.
What Is BigSeller?
BigSeller is a cloud-based ERP (Enterprise Resource Planning) system designed specifically for Southeast Asian marketplace sellers. It connects to Shopee, Lazada, and TikTok Shop via API, pulling in all your orders, products, and inventory into a single dashboard. You manage everything from one place rather than logging into three separate Seller Centres.
BigSeller is built in Malaysia and China and operates across all major SEA markets: Singapore, Malaysia, Philippines, Thailand, Indonesia, Vietnam, and more. Their blog and help centre are available in English, Bahasa, Thai, Filipino, and Mandarin.
The tool covers four main areas: product listing management, order and fulfilment processing, inventory control, and financial tracking — plus several AI-powered add-ons for generating listing copy.
BigSeller Review: Key Features for Shopee and Lazada Sellers
Cross-Platform Listing Management
Create a product once in BigSeller and publish it to Shopee, Lazada, and TikTok Shop simultaneously. When you need to update a price, change a photo, or edit a description, you make the change once and push it across all platforms. This replaces logging into three Seller Centres to do the same edit three times.
BigSeller also includes a product scraper that lets you find trending products on Shopee or Lazada and import the listing data directly into BigSeller for editing and republishing. Useful for dropshippers and resellers who work from existing listings.
AI Listing Generator
BigSeller’s built-in AI listing generator creates product titles and descriptions from a short input. You enter the product name and key features, and it outputs a draft listing optimised for Shopee or Lazada search. The output is reasonable for straightforward products — apparel, accessories, home goods — but works better as a starting draft that you review and refine rather than a finished copy you publish directly.
Order Management and Fulfilment
All orders from all platforms flow into one BigSeller order list. You can batch-print shipping labels, mark orders as packed, and trigger courier pickups from the same screen — without switching between Shopee Seller Centre, Lazada Seller Centre, and TikTok Shop Seller Centre separately. For sellers doing 50+ orders a day, this is where BigSeller saves the most time.
Real-Time Inventory Sync
When a product sells on Shopee, BigSeller automatically deducts the stock count and updates the available quantity on Lazada and TikTok Shop in real time. This prevents the most common pain point for multi-platform sellers: overselling an item that’s already sold out elsewhere. The sync typically takes seconds after an order is confirmed.
Financial Tracking and Profit Calculator
BigSeller includes a built-in profit calculator that factors in your product cost, platform commission (Shopee 2–8%, Lazada 2–6.5%, TikTok Shop fees), shipping, and promotional discounts. This matters because many sellers discover too late that a product priced to sell during 9.9 or 11.11 campaigns is actually losing money once all fees are deducted. The Pricing Template feature also auto-calculates recommended selling prices based on your cost and target margin.
Wallet Transaction Dashboard (February 2026 Update)
BigSeller’s February 2026 update added a Wallet Transaction feature that integrates payout data from Shopee, TikTok, and Lazada into a single financial dashboard. Previously sellers had to log in to each platform separately to reconcile payouts. Now you see all your earnings, deductions, and withdrawals in one view.
BigSeller Pricing — What Does “Free” Actually Mean?
BigSeller markets itself as a free e-commerce ERP, and the core features are genuinely free for most SEA sellers. Here’s how their pricing structure works:
| Plan | Cost | What’s included | Best for |
|---|---|---|---|
| Free | $0 | Product listing sync, order management, inventory sync, basic financial tracking. Covers all 3 platforms. | Sellers with moderate order volume getting started with multi-platform management |
| VIP / Paid Plans | Custom pricing | Higher API call limits, advanced automation, priority support, additional integrations | High-volume sellers doing hundreds of orders daily or managing 5+ stores |
Note: BigSeller also offers promotional bundles with Duoke (a multichannel customer service tool) at certain periods. Check bigseller.com for current plan details and ongoing promotions in your market.
The practical answer for most Shopee and Lazada sellers: if you’re doing under a few hundred orders a day across your stores, the free plan covers everything you actually need. The paid plans become relevant when you’re running high-order-volume operations that need advanced automation or dedicated support.
What We Like
- It’s genuinely free for most sellers. Unlike tools that call themselves “free” but limit you to 5 products or 10 orders, BigSeller’s free plan handles real store volumes. Most SEA sellers will never need to upgrade.
- Inventory sync prevents overselling. For any seller on multiple platforms, the real-time inventory sync is the single most valuable feature. Avoiding one stock-related cancellation penalty can pay for a VIP plan several times over.
- Built for SEA, not adapted from it. Unlike generic ERP tools designed for Western markets, BigSeller is built around Shopee and Lazada’s actual systems, promotions (9.9, 11.11, Hariraya, CNY), and local logistics providers. The platform genuinely understands SEA marketplace mechanics.
- Wallet Transaction dashboard saves reconciliation time. Having Shopee, TikTok, and Lazada payouts in one view is a significant quality-of-life improvement for sellers who previously spent hours each week reconciling earnings across platforms.
- Active development. BigSeller ships updates regularly. The February 2026 release alone added Shopee Add-on Deal support, Wallet Transaction, and improved pricing templates — features that directly address real seller problems.
What Could Be Better
- AI listing generator needs review. The AI-generated listing copy works as a starting draft but often produces generic output that still needs significant editing before it’s ready for a Shopee or Lazada listing. Don’t expect to publish it as-is for competitive categories.
- Learning curve for new users. BigSeller covers a lot of ground, and the interface takes time to learn. Sellers who are new to ERP tools may need a few days to navigate the product sync, order management, and inventory sections confidently.
- Documentation can be inconsistent. Some help articles are excellent; others are outdated or only available in Mandarin. English-language sellers occasionally need to use translated articles or contact support directly.
- API limits on the free plan. If you’re running a very high-volume store (hundreds of orders per day), you may hit API rate limits on the free tier that cause delays in sync. At this scale, the VIP plan becomes necessary.
BigSeller vs Shopdora: What’s the Difference?
A common question from Shopee sellers: if I’m already using Shopdora for analytics, do I also need BigSeller?
The tools do different things. Shopdora is an analytics and market research tool — it helps you find winning products, track keywords, and monitor competitors. BigSeller is an operations tool — it helps you manage orders, sync inventory, and process fulfilment across platforms. Most serious sellers use both: Shopdora to find and validate products, BigSeller to run operations once the store is active.
Who Should Use BigSeller?
| BigSeller is a good fit if you… | Consider alternatives if you… |
|---|---|
| Sell on 2 or more platforms (Shopee + Lazada + TikTok Shop) | Only sell on one platform and don’t plan to expand |
| Process 20+ orders per day and want a single fulfilment workflow | Run a very small store with under 10 orders a day where manual management is still feasible |
| Want real-time inventory sync to prevent overselling across platforms | Have a single warehouse system already integrated with your platforms |
| Need profit tracking that accounts for Shopee and Lazada commissions and fees | Are primarily looking for product research and competitor analytics (Shopdora is better for that) |
| Are a dropshipper or reseller importing products from 1688 or other sources | Only sell a small, fixed catalog with no active product sourcing |
Frequently Asked Questions About BigSeller
Is BigSeller really free for Shopee and Lazada sellers?
Yes — BigSeller’s core features (cross-platform listing sync, order management, inventory sync, basic financial tracking) are free for SEA sellers. There are paid VIP plans for higher volumes and advanced features, but most sellers doing under a few hundred orders a day will find the free plan covers everything they need.
Does BigSeller work with TikTok Shop?
Yes. BigSeller connects to Shopee, Lazada, and TikTok Shop. Orders from all three platforms flow into one dashboard, and inventory is synced across all three in real time. It also supports TikTok Shop-specific features like Shopee Add-on Deal management and GMV tracking.
Can BigSeller help prevent overselling on Shopee?
Yes — this is one of its most valuable features. When a product sells on any connected platform, BigSeller deducts the stock count and updates the available quantity everywhere else automatically. This prevents the most common cause of seller penalties: selling a product you no longer have in stock.
What markets does BigSeller support?
BigSeller supports all major SEA markets: Singapore, Malaysia, Philippines, Thailand, Indonesia, Vietnam, and more. It connects to country-specific versions of Shopee (SG, MY, PH, TH, ID, VN, TW) and Lazada (SG, MY, PH, TH, ID, VN). Currency and tax settings are configurable per market.
Is BigSeller safe to connect to my Shopee account?
BigSeller connects via Shopee’s official Open API, which is the authorised third-party integration method Shopee supports for ERP tools. You authorise the connection through your Shopee Seller Centre — BigSeller does not ask for your username and password directly. This is the same method used by other authorised Shopee integrations.
BigSeller Verdict: Our Final Rating
Our BigSeller review for Shopee and Lazada sellers gives it 4.5 out of 5.
For any seller operating on more than one platform, BigSeller is the most practical free tool available in SEA right now. Real-time inventory sync, unified order management, and multi-platform listing control solve real operational problems — and the fact that it’s free for most sellers makes the decision easy.
The AI listing generator is useful as a draft starting point but isn’t strong enough to publish without editing. The learning curve is real for first-time users. But once you’ve set it up and connected your stores, you’ll wonder how you managed without it.
If you’re currently logging into multiple Seller Centres daily to manage orders and inventory, start your BigSeller setup today — it’s free and the core functions work well from day one.
