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
  • Lightspeed
  • Erply
  • EPOS Now


Accounting & sync:

  • QuickBooks Online
  • Xero
  • Cin7/DEAR
  • A2X
  • Zapier/Make


Retail or restaurant if your till isn't talking to your books, I'll find out why and fix it.


Message me before ordering so I can confirm your stack.
