One-liner

A S$29/month web tool for Singapore Shopee, Lazada, and TikTok Shop sellers that computes true per-SKU margin after all fee layers and exports IRAS-compliant income figures for quarterly GST and annual income tax filing.

Opportunity Source

Trend signal. Shopee added a 5% technical support fee in February 2026 on top of existing commissions and transaction fees, pushing total effective take rates to 16-25% depending on category and programs enrolled. The HardwareZone forum thread "Shopee raises Commission Fees 1 Jan 2026" shows 3+ pages of active seller backlash, with sellers reporting they now have no visibility into whether individual products are profitable. Many are raising prices 50% or migrating to Lazada without actual margin data to guide the decision.

Pain signal. The fee structure across three platforms is now genuinely difficult to model:

• Shopee: commission (2-8% by category) + transaction fee (2.18%) + technical support fee (5% from February 2026) + cashback program cost + late shipment penalty risk
• Lazada: commission (4-6%) + transaction/processing fees (~10% total)
• TikTok Shop: commission (varies by category) + transaction fee (2.18%)

Each platform has different payout timelines, fee deduction logic, and reporting formats. Sellers receive net payouts and cannot easily work backward to gross margin.

IRAS compliance gap. Singapore IRAS requires marketplace sellers to declare gross sales (the selling price paid by buyers) for income tax purposes, not the net payout received. Many sellers undercount their turnover by looking only at bank deposits. This creates an additional compliance risk beyond profitability confusion.

Existing tool gap. PayRecon handles Shopee-only payment reconciliation but is Malaysia-primary and does not produce IRAS-formatted income tax exports. SiteGiant adds reconciliation as an addon but is not SG-tax-aware. OneCart focuses on inventory sync and fee calculation without tax output. Osome provides human-assisted accounting at S$200+/month; there is no self-serve tool at S$29/month.

Who Buys This

Singapore-based individual sellers and small merchant teams (1-5 people) selling across Shopee + Lazada + TikTok Shop simultaneously. Most have 50-500 active SKUs. They are not GST-registered (below S$1M turnover), so they handle their own income tax filing via myTax Portal. They spend 2-5 hours per week manually reconciling platform statements. Many are currently making product and pricing decisions without real margin data.

Estimated addressable pool: Singapore has over 200,000 registered marketplace sellers across the three platforms, with active multi-platform sellers estimated at 40,000-80,000.

Product Concept

1. OAuth-based connection to Shopee Seller Centre, Lazada Seller Centre, and TikTok Shop Seller Centre APIs (using published API programs, not scraping)
2. Auto-pulls payout statements, order data, and fee breakdowns
3. Applies the current Singapore fee schedule for each platform and product category to compute gross sales, total fees paid, and net margin per SKU and per order
4. Dashboard: SKU-level profitability ranking, fee trend chart, platform comparison
5. Tax export: annual income summary in IRAS-expected format (gross receipts by income type), quarterly GST exposure flag for sellers approaching the S$1M threshold
6. Price suggestion: given a target margin %, what price should each SKU be listed at across each platform?

Monetisation: S$29/month (under 500 orders), S$59/month (up to 5,000 orders). Annual plan at 2 months free.

7-Dimension Triage Scores

Dimension	Score	Rationale
Demand pull	5/5	Active forum complaints + fee increases creating urgent pain; HWZ thread evidence in assets/
Acquisition feasibility	4/5	HardwareZone, Telegram seller groups, r/singapore, Facebook F-commerce groups are reachable; Shopee/TikTok Shop seller communities are active
Agent advantage	4/5	Fee-schedule updates, API ingestion, and margin calculation are well-suited to automation; no skilled human judgment required in the core loop
Low-volume economics	4/5	S$29/month at 50 users = S$1,450 MRR, profitable at small scale; API costs are low
Operator hand lightness	4/5	Once API connections and fee tables are built, updates are low-touch (fee schedule changes a few times per year); no per-client manual work
Market trend	5/5	Fee increases ongoing; TikTok Shop adding third platform complexity; cross-border ecommerce growing
Policy redline	4/5	No legal services or financial advice; must carry "this is an estimate, verify with your accountant" disclaimer; Shopee/Lazada API terms must be followed (no scraping); minor risk, manageable

Triage total: 30/35

Hypotheses for Research Stage

• Verify: are Shopee Seller Centre API, Lazada Open Platform API, and TikTok Shop API accessible to third-party developers at reasonable cost/terms?
• Verify: what is the realistic number of active multi-platform Singapore sellers (Shopee + at least one other)?
• Check: does A2X or BigSeller already provide SG-specific real-margin + IRAS export? If so, at what price?
• Check: are there PSG-pre-approved accounting tool categories this could qualify under?

Red Lines and Disclaimers

• Cannot store Singpass credentials or IRAS account data
• Must disclaim: "margin estimates; verify fee schedules with each platform; for definitive tax filing, consult an accountant"
• API terms for each platform: must check commercial redistribution allowances for payout data
• Not a GST filing tool (GST filing requires GST-registration and InvoiceNow); this is for income tax pre-preparation only
