0 oversells through BFCM Sync Shopify, NetSuite, your OMS, your 3PLs, and your customer database in real time, across every channel, every fulfillment center, every store.
E-commerce is the discipline where every sync delay translates directly into a refund, a chargeback, or a one-star review. Here's where it breaks first.
Stock decrements happen in different systems at different times. By the time the OMS catches up, the storefront has already sold inventory that physically isn't there.
Shopify, Amazon, Walmart, TikTok Shop, retail POS, each with its own API, its own webhook quirks, and its own failure modes. Routing one order through all of them takes a custom job per channel.
Marketing emails go out based on Klaviyo's view of the customer. Service answers tickets based on Shopify's. Sales calls based on Salesforce's. Three different lifetime values, three different addresses, three different sources of truth.
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 covers storefront, OMS, ERP, fulfillment, marketing, and customer data on one platform.

Segment As a data company, we understand the importance of keeping your data secure. Stacksync is built with security best practices to keep your data safe at every layer, and is DPF-certified for US, EU, UK and CH data transfers.
Let your users access Stacksync from your centralized user management systems. Works with Okta, Azure, Google SSO and more.
Immediately get alerted about record syncing issues over email, Slack, PagerDuty and WhatsApp. Resolve issues from a centralized dashboard with retry and revert options.
Securely connects to your systems with:
How fast does inventory propagate?
Sub-second for connectors that support webhooks (Shopify, BigCommerce, ShipBob), and 1–5 seconds for poll-based connectors. Stacksync defaults to whichever is fastest available.
Can we handle multi-warehouse / multi-location inventory?
Yes. Stacksync syncs inventory at the location level, each store, fulfillment center, or 3PL maintains its own pool, with cross-channel allocation rules configurable in the UI.
What happens during BFCM at peak load?
The platform scales horizontally and is tested at 100k+ orders per minute. Customers like Gladia have run BFCM through Stacksync with zero oversells.
Can we sync to retail POS in stores?
Yes, Lightspeed, Square, Shopify POS, and most enterprise POS systems are supported. Inventory and customer data sync between retail and online in real time.
