Frequently Asked Support Questions
How do I import order CSVs from Shopify or Amazon?
Export orders from Shopify (Orders → Export → All orders as CSV) or Amazon Seller Central (Reports → Fulfillment → All Orders). Click "Upload CSV" on the audit tool. Headers are mapped automatically.
Does EcomNexusHub store customer personal information?
No. Our proprietary Zero-PII engine scrubs customer names, street addresses, phone numbers, and payment details entirely inside your browser before computing state totals.
How does subscription cancellation or refund work?
You can cancel anytime in 1 click via your billing settings or Stripe Customer Portal. All paid plans include a 14-day no-risk money-back guarantee. View our Refund Policy.
Does EcomNexusHub provide formal CPA tax filing?
EcomNexusHub provides automated threshold tracking and alerts. We do not prepare or file tax returns. We provide clear CSV reports ready for your certified public accountant.
