Is Inseller a replacement for BigSeller?

No. BigSeller sits in the multichannel sync and listing/inventory category; Inseller is a profit-analytics layer that reconciles actual platform fees to show real net profit. They solve different problems.

Can I use both BigSeller and Inseller together?

Yes, and many Malaysian sellers do. BigSeller keeps stock, listings and orders aligned across channels while Inseller tells you which orders, SKUs and live sessions actually made money.

Which one should a new Shopee / TikTok Shop seller start with?

If your bottleneck is overselling or manual listing across channels, start with a sync tool; if you sell steadily but do not know your true margin, start with a profit layer. Check each tool's current plans and features on its own site.

Does BigSeller show my real net profit after fees?

Operational reporting in sync/ERP tools is usually built around orders and stock, not settlement-accurate margin, so profit there is typically estimated. Confirm on their site what fee handling they offer today.

Inseller vs BigSeller: Which Does a Malaysian Shopee / TikTok Seller Need?

Short answer: They are not competitors — they do different jobs. BigSeller lives in the multichannel sync category: listing management, order processing, and inventory alignment across Shopee, TikTok Shop, Lazada and more. Inseller is a profit layer: it reconciles your actual platform fees against settlement and shows real net profit per order, per SKU, and per live session. A lot of Malaysian sellers end up running both. The real question is which pain is bleeding you right now.

What job does each tool actually do?

A multichannel sync / listing tool exists so you stop overselling and stop copy-pasting the same product into five Seller Centres. Its wins are operational: one stock pool, bulk listing, order printing, fewer manual mistakes across channels. That is genuinely hard, genuinely valuable, and if that is your bottleneck a sync platform is hard to beat.

A profit layer exists for a different question: of everything I sold this month, what did I actually keep? That answer only appears after you subtract commission, transaction fees, the per-order platform support fee, COGS, ad spend, affiliate commission, live costs, and returns — reconciled against the real settlement number, not a rate-card estimate.

Where does BigSeller (the sync category) genuinely win?

Give the operations tools their due. If your day is spent managing listings across many channels, printing waybills in bulk, or fighting stock that drifts out of sync between Shopee, TikTok and a warehouse, a multichannel platform is doing heavy, useful lifting. Breadth of channel coverage and order-processing throughput is exactly what that category is built for. Inseller does not try to replace that.

For their exact channel list, plan tiers, and current feature set, check BigSeller's own site — those change, and we are not going to quote numbers that may be stale.

Where does Inseller win?

Inseller answers the question sync tools were never built to answer: which of my orders, SKUs and live sessions actually made money?

The gap matters most in Malaysia because the fee stack is heavy. As of the Feb 2026 rate update — confirm on the official Seller Centre rate cards — a TikTok Shop programme seller can pay roughly:

Commission ~10.26% + transaction fee ~3.78% + a per-order platform support fee (~RM 0.54), before any ads or affiliate commission.

Shopee is in a similar range once you add commission (~10.26%), the free-shipping/service programme fee (~5.94%), the transaction fee (3.78%, or 4.86% on SPayLater instalment orders), the per-order support fee, and 3.24% extra on live-attributed orders. When ~20% of order value plus a flat fee leaves before COGS, a bestseller can quietly run at a loss. Estimated fees hide that; actual settlement reconciliation exposes it.

So which should you pick?

Pick a multichannel sync tool if your number-one pain is keeping stock, listings and orders aligned across channels and a warehouse. That is a real, worth-paying-for problem.
Pick Inseller if your number-one pain is not knowing your true per-order or per-live profit — if revenue looks fine but you cannot say which SKU is quietly losing money. See how to calculate your real profit and why a sync tool and a profit tool are different jobs.
Run both — the common end state — when you want operational reach and profit clarity. They stack cleanly: one keeps your operation clean, the other keeps your margin honest.

If you want to sanity-check the fee side yourself first, the TikTok fee calculator, Shopee fee calculator and profit margin calculator are free.

About Inseller

Inseller was built by a seller running an RM-scale TikTok Shop and Shopee business who got tired of not knowing the real number. It connects your stores and shows actual net profit per order, per SKU and per live session using reconciled platform fees — not estimates. It is not an ERP and does not pretend to be; it is the profit brain that sits alongside whatever sync stack you already run.
