Independent research

Shopping research tools

Estimate costs with your own current rates. Every output shows its assumptions so you can review the result before acting.

Available tools

Cost planning

Combine product price, exchange rate, billable weight, international shipping, service fees, and a tax estimate.

Inspection planning

Turn reviewed product templates into photo angles, issue checks, suggested actions, and a printable checklist.

Route comparison

Compare reviewed service, payment, storage, QC, and shipping evidence for the same destination and scenario.

Shipping planning

Estimate the chargeable weight of a parcel from dimensions, parcel count, the route divisor, and any minimum billable weight.

Currency planning

Convert CNY and foreign shopping currencies with your own current rate and a visible, fixed-point result.

Rates are never presented as current unless a source and check date are available.
Calculations use decimal fixed-point arithmetic rather than floating-point money totals.
Tax, customs, packing, and third-party decisions can change the final charge.

A practical research path

Start with evidence
Review the product details, source links, media status, and any known limitations before calculating.
Model the uncertainty
Use your own current rates and compare a low, mid, and high estimate instead of relying on a single number.
Keep a review trail
Print or copy a checklist, record the source date, and revisit the estimate when route or policy details change.
