I will automate your ecommerce bookkeeping, inventory, and order tasks


About this gig
The back office is where ecommerce margins die quietly: manual invoice entry, oversells that eat marketplace ratings, restock calls made from stale spreadsheets.
I fix that for a living. As the operations engineer for an 8-figure multi-channel ecommerce operator, 15 automations I built run its back office unattended on a 26,000 SKU catalog across Amazon, Walmart, eBay, and Shopify. Hour one of inventory monitoring surfaced 22,849 exceptions, 184 of them oversold. The invoice pipeline reconciles vendor bills line by line, 1,027 line items cent exact, and enters them in QuickBooks: 32 bills in one unsupervised business day, zero wrong actions. 1,600+ automated tests behind it.
What I automate: invoice entry and bookkeeping, oversell prevention, order operations, daily recaps and exception alerts, data entry.
How it works: show me the process however is a few screenshots, or just describe it. No calls, ever. I build it with tests, an audit trail, and an off switch, then hand it back with a walkthrough video and documentation you own.
