The pressure on retailers

Three integration problems Stacksync was built to solve.

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.

01 — Inventory

Stock disagrees across web, store, and 3PL

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.

OMS & POS
02 — Customer

One customer, six different IDs

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.

CRM & LOYALTY
03 — Marketplaces

Amazon, Walmart, and TikTok each want different feeds

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.

CHANNELS
PLATFORM

Six products. One Platform.
Replace many legacy vendors.

Every tool Stacksync replaces is one fewer vendor, one fewer bill, one fewer integration to maintain.

Customer story

Gladia kept inventory in sync across web, retail, and 3PL — in real time.

Gladia is a DTC home-goods brand running Shopify Plus, NetSuite, seven owned retail stores, and three 3PLs. Their ops team needed real-time inventory and one customer record across every channel — without spending their year writing connectors.
