Most e-commerce operations tools charge $200-$500/month, lock you into their ecosystem, and still don't fit your workflow. StackFast builds exactly what you need, from $5K. You own it.
Real-time stock levels across channels. Low-stock alerts, purchase order automation, warehouse location tracking. Stop selling what you don't have.
One retailer eliminated overselling entirely — previously happening 3-5 times per week.
See every order across every channel in one place. Fulfilment status, shipping tracking, returns, exceptions. Stop tabbing between Shopify, email, and spreadsheets.
Fulfilment team processed 40% more orders per day with a unified dashboard.
Track supplier relationships, automate reordering, and manage purchase orders. Know what's coming, when it arrives, and what it costs.
Cut reordering time from 4 hours/week to automated alerts.
Connect your Shopify/WooCommerce store to Xero, your 3PL, your suppliers, and your internal tools. Automate the data flows you're currently doing by hand.
