The Problem
Ecommerce + QuickBooks sync creates silent duplicates
When Shopify, Stripe, or Amazon sales feed into QuickBooks through automated sync tools, the same revenue can be recorded twice — once from the platform and once from the bank feed. These entries look legitimate on their own, so they survive reconciliation unchecked.
Sync Doctor reads your QuickBooks data and surfaces these patterns before they distort your P&L, inflate your tax basis, or reach your accountant.

What We Detect
Four categories of QuickBooks data quality issues
Duplicate Revenue
Same sale recorded by both a platform sync and the bank feed, inflating income.
Duplicate Deposits
The same bank deposit matched to multiple transactions, overstating your cash position.
Orphan Deposits
Deposits with no matching sales receipt or invoice — funds in your bank that are unaccounted for.
Fee Mismatches
Processor fees that don't align with the net deposit, indicating a recording error.
