INTEGRATIONS
Built to connect your stack end to end
When systems do not talk to each other, someone spends the week reconciling exports instead of trading. Merchmix provides two-way software integration across your ERP, ecommerce, POS, finance and marketing systems, reading from them continuously and writing your decisions back to them.

How the connection actually works
Merchmix connects those systems into one operating layer. As outlined in our retail software integrations guide, every plan, buy, allocation and markdown runs off the same live picture, providing clean two-way integration without manual data exports.
Connect once
Authenticate your systems once, including multiple storefronts, brands or entities under one account. Merchmix handles the connection, not your IT team.
Reads continuously
Incremental syncs, scheduled pulls and event-based updates, with a manual re-sync whenever you need one. No overnight batching, no waiting for Monday's export.
Writes back on approval
Nothing reaches a live system until a person approves it. Every write is logged and auditable, and your ERP stays the system of record.
Every connection, and whether it is actually running
Most platforms ask you to trust that a connection is working. Merchmix shows you.
Live status on every connection
Active, syncing or needs attention, at a glance. When authentication is about to expire, you know before a sync fails.
Last sync on every system
Minutes, not overnight. You can see how current a number is before you make a decision on it.
Multiple storefronts, entities and warehouses

Frequently asked questions
Whatever you run, we connect to it
Mid-market retailers rarely run a clean stack. There is usually a legacy warehouse system, a regional POS, a PLM nobody wants to replace, or a supplier who still sends a flat file instead of connecting through a supplier portal.
Merchmix connects to those too, across PLM, WMS, 3PL, EDI, SFTP and direct API. If it is not already connected, we build the connector during implementation rather than billing it as a project afterwards, and it is supported, monitored and versioned exactly like every other connection.
Enterprise vendors answer this question in a statement of work. We answer it before you book.
