Outputs can be wrong
Tools may contain software defects, rounding differences, incomplete models, misunderstood inputs, or outdated explanatory material. An output can look precise and still be inappropriate for your business. Independently verify important results against source records, current platform documentation, contracts, and qualified professional advice.
Profit, margin, fees, ROAS, and bundles
Economics calculators are simplified scenario models. They may exclude taxes, duties, refunds, overhead, chargebacks, currency conversion, payment or marketplace tiers, attribution differences, discount rules, cash timing, and other costs. Marketplace rates are user-entered and are not verified or endorsed by any platform.
Catalog, CSV, titles, variants, and SKUs
Generic validation does not guarantee that a file will import or comply with a destination schema. Generated variants may include impossible combinations. Generated SKUs are unique only within the current result and may collide with existing records. Title checks do not evaluate trademark, style, prohibited-content, or search policies. Preserve originals, inspect previews, and test a small reversible import first.
Inventory and returns
Reorder estimates assume stable average demand and supplier lead time; they do not model variability, service levels, seasonality, promotions, minimum orders, backorders, or cash constraints. Returns estimates simplify refunds and recoverability and may not reflect provider fee, sales-tax, exchange, write-down, or accounting rules.
No professional relationship or affiliation
Using the Service does not create an accountant-client, attorney-client, adviser-client, agency, fiduciary, partnership, or other professional relationship. References to ecommerce concepts or platforms do not imply certification, sponsorship, affiliation, or endorsement.
As-is service
The Service is provided as-is and as-available without warranties of accuracy, completeness, reliability, or fitness for a particular purpose. Liability is limited as described in the Terms of Use and only where permitted by law; non-excludable statutory rights remain unaffected.
