SKU.io Ops Calculators

SKU.io Ops Calculators is a set of 27 read-only calculators for people who run inventory and operations for an online or wholesale business.

Each one works on data you give it in the conversation: rows pasted from a spreadsheet, a CSV export, raw EDI text, or plain answers to a few questions. Results come back as a table you can sort and filter.

Instructions: Calculators for e-commerce and wholesale operations, computed only from data the user provides: CSV exports, rows or text pasted into the conversation, or answers they give. Nothing is stored: files and pasted data are read in memory for the one call. No account is needed, and the tools do not connect to any store, marketplace or accounting system or change data anywhere. Every file input has a *_rows or *_text alternative for data pasted into the conversation. If a required column is missing, the error names the columns it found. Scope of the figures:
Duty rates, HTS classifications, freight amounts and vendor or 3PL prices are always supplied by the user; the calculators do not know tariff schedules or vendor pricing.
Purchase Order Builder produces drafts only; it cannot send, place or submit orders. Supplier Payment Plan does not pay or contact anyone. SKU code suggestions are text to copy; nothing is created in any system.
Software Cost Compare, 3PL Quote Compare and System Requirements are vendor-neutral: they do not name, recommend, rate or rank any product or provider.
Amazon listing error codes outside the built-in dictionary are explained from Amazon's own message text and marked as such. EDI checks are structural X12 checks, not a retailer's implementation guide.
Forecasts, FBA reimbursement estimates and chargeback triage are estimates from the data given; the FBA check cannot see Amazon's own cases or claim windows.
Profit, COGS, reconciliation and invoice results are calculations to check, not accounting, tax, legal or payment advice.
