About this gig
Is your Shopify POS, QuickBooks, or Xero setup creating duplicate customers, mismatched inventory, and reconciliation headaches?
Most "integration experts" just connect the apps and leave. That's exactly how stores end up with bad data spreading across every system.
I do it differently. I start by answering the question that actually matters: which system should be the source of truth for each data type products, SKUs, inventory, customers, sales, payments, refunds, taxes, and deposits. Then I configure the sync around that decision so problems stop repeating.
What I fix:
- Duplicate customers and products created by broken syncs
- Inventory mismatches between POS, online store, and accounting
- Payment and deposit reconciliation errors
- Orders not syncing (or double-syncing) into QuickBooks/Xero
- Retail POS sales, online orders, refunds, and trade/B2B customer workflows
POS systems I work with:
- Shopify POS
- Square POS
- Toast POS
- Clover POS

Which integrations do you support?
Native Shopify–QuickBooks/Xero connectors, plus third-party sync apps (A2X, Amaka, MyWorks, Zapier, Make, Wrightway-style middleware). If you use something unusual, message me first.
Will you need access to my live store?
For the Basic audit I can work from exports and screenshots plus collaborator access. For fixes I'll need staff/collaborator access to Shopify and read access to your accounting platform. All changes are tested before going live.
My data is already a mess duplicates everywhere. Can you clean it?
Yes Premium includes cleanup of up to 500 records. Larger catalogs are quoted as a custom offer after the audit.
