Shopify Payout Fee Reconciler for UK Tax Returns

90% Confidence Medium Market Medium Difficulty $5k-15k MRR Updated May 17, 2026

The Opportunity

An app that automatically calculates Shopify transaction fees, refunds, chargebacks, and payout differences in a tax-friendly format for UK merchants. It would generate monthly and fiscal-year summaries that align with accountant expectations and HMRC reporting needs.

"Merchants need accurate historical Shopify fee totals for UK tax returns, but Shopify’s built-in invoices only started covering some periods recently and the available payout figures do not reconcile cleanly with refunds and chargebacks."

Detailed Analysis

Proposed Solution

Pull transaction, payout, refund, and fee data from Shopify Admin API and generate reconciled reports by tax period. Include retroactive calculations, exportable CSV/PDF summaries, and clear definitions of gross vs net vs fee totals for accountants.

Target Audience

UK Shopify merchants, ecommerce bookkeepers, and accountants handling Shopify-based businesses

Competitive Landscape

A2X, Link My Books, Xero/QuickBooks integrations, BeProfit, Intuit-style bookkeeping connectors

Implementation Notes

Use Shopify Admin API and payout/transaction data to reconstruct fee totals by day, month, and tax year; support UK year-end dates, refunds, chargebacks, and timezone-safe reporting; add exports for accountants, audit trails, and mapping rules for edge cases where Shopify invoice data is incomplete or delayed.
