90% less integration maintenance Connect your commerce, OMS, ERP, POS, and customer systems in real time. Stacksync gives retailers and DTC brands one integration platform, so orders, inventory, and customer events flow across every channel without overnight syncs.
Modern retail runs on a chain of commerce, OMS, ERP, POS, and CRM, with marketplaces and 3PLs hanging off the side. The cracks show up in oversells, lost loyalty data, and on-shelf availability.
Your site says in stock, the store says sold, and the 3PL says shipping today. Without two-way sync, you oversell on Black Friday and your customer hears about it from a confirmation email.
A purchase on Shopify, a return at the store, and a loyalty point in Klaviyo should be one customer record. Today they're three, and your marketing team can't run a unified campaign.
Every marketplace has its own SKU model, return policy, and update cadence. Stacksync normalizes them into one feed so you stop running parallel ops teams per channel.
Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.
Changes made in one platform automatically update across all connected systems in real time, eliminating data silos and reducing errors.
Stop building brittle API scripts. With Stacksync, you can trigger complex automated workflows using simple SQL commands.
Expose every enterprise system to your agents through a single MCP layer. Claude, ChatGPT and Gemini get production-grade tools without custom glue code.
Handle massive traffic spikes without losing a single event. Queues buffer your data during surges, ensuring strict ordering and reliable delivery.
Interact with your CRM, ERP, and payment tools as if they were just another table in your database. Say goodbye to rate limits and complex API documentation.
Transform legacy EDI complexity into simple database interactions. Stacksync automatically parses incoming EDI documents directly into your database tables.
Stacksync ships with native, typed connectors for the systems retailers and DTC brands actually run. Each one is two-way, schema-aware, and battle-tested at peak.
