Solutions/Profit margin
E-commerce profit calculator for Shopee sellers
GMV grows. Margin shrinks. DataGlass is the e-commerce profit calculator that reconstructs every order — COGS, Shopee commission fee, platform structure fees, ad cost, fulfillment, vouchers — and turns the math into a clean profit breakdown per SKU. The profit insight every marketplace seller needs to know which products fund the business and which ones bleed it.
01/Problem
What sellers see
Revenue is up. A slow quarter passes and the bank balance has not moved. The seller-centre dashboards show GMV; they do not show the all-in cost of selling that GMV — the Shopee commission fee, the Lazada platform fee, the TikTok Shop transaction fee, the seller-funded voucher, the attributed ad cost, the fulfillment. Without a real profit breakdown those costs stay invisible until they have already eaten the margin.
- GMV growing while net profit stays flat or drops
- Bestsellers that turn out to be the lowest-margin SKUs once Shopee commission fees and ads are deducted
- Campaigns that look successful but are quietly funded by margin elsewhere
- Platform structure fees (commission, transaction, free-shipping subsidy) that nobody on the team can break down per SKU
- COGS spread across spreadsheets that have not been reconciled in months
02/Detection
What DataGlass detects
DataGlass models true profit per order by combining platform data with COGS, marketplace fees (Shopee commission fee, Lazada platform fee, TikTok Shop transaction fee), ad attribution, fulfillment, and seller-funded discounts. The output is a per-SKU profit breakdown with the e-commerce insight a marketplace operator can actually act on.
- SKUs where contribution margin is negative once Shopee commission fees, ad cost, and fulfillment are applied
- High-velocity SKUs whose unit economics no longer cover ad cost or platform structure fees
- Categories where marketplace fees consume more margin than the seller realizes — broken down per platform
- Discounts and vouchers that lifted GMV but eroded margin once the full profit breakdown is computed
03/Action
Recommended actions
Decisions that move margin in the next 30 days. Ranked by expected lift on contribution margin, with a full profit breakdown attached to every recommendation.
- 01
Reprice low-margin SKUs
Surface the price points where contribution margin tips back into the green — net of Shopee commission fee, ad cost, and fulfillment — without killing demand.
- 02
Retire SKUs that lose money even at full price
Identify products whose all-in cost (COGS + platform structure fees + ads) exceeds their realistic price ceiling.
- 03
Shift promotion to high-margin SKUs
Move ad and discount budget from low-margin bestsellers to high-margin SKUs that can absorb the boost — informed by the full per-SKU profit breakdown.
- 04
Renegotiate fees and shipping
Surface the categories and SKUs where Shopee/Lazada/TikTok Shop fees and fulfillment are the biggest margin lever — useful when negotiating with suppliers or 3PLs.

Prediction and Risk Optimization Under Uncertainty: A Cross-Domain Meta-Review of Methods in Finance, Operations, Causal Inference, and E-Commerce Decision Intelligence
A structured meta-review (213 primary works, 254 references) arguing that mature decision systems across finance, operations, insurance, energy, healthcare, causal inference, and e-commerce share four primitives — calibrated probabilistic models, coherent risk-aware objectives, explicit operational constraint sets, and principled exploration. Eleven worked cases ground the framework, with the DataGlass marketplace ad-budget system as the connecting tissue.

04/FAQ
Frequently asked
For every order, DataGlass deducts COGS, marketplace fees (Shopee commission fee, Lazada platform fee, TikTok Shop transaction fee), attributed ad cost, fulfillment, and any seller-funded vouchers from revenue. The result is a per-order profit breakdown that rolls up into contribution margin per SKU — the per-unit profit that funds the business.
Yes. Every Shopee, Lazada, and TikTok Shop platform fee is modeled per category and per program — commission fee, transaction fee, payment-processing fee, free-shipping subsidy, and seller-funded voucher. The profit breakdown shows each line so the math is auditable per SKU.
Yes. Upload what you have via CSV or XLSX with column auto-mapping. For SKUs without a COGS, DataGlass infers a starting estimate and flags it so you can refine it over time. The profit calculator still produces a directional profit insight while you fill the gaps.
Gross margin only deducts COGS from revenue. Contribution margin also deducts marketplace fees (commission, transaction, platform structure), ad cost per unit, fulfillment, and vouchers — it reflects real per-unit economics on a marketplace and is the number the DataGlass profit breakdown surfaces.
