Whether fulfillment runs through one 3PL with dozens of sites or a mix of owned DCs and global partners, packing decisions shouldn't vary by building. The Packing Control System (PCS) manages everything from one UI and executes it everywhere.

Most multi-site operations don't have one packing standard. They have as many as they have buildings. Rules live in individual WMS configurations, maintained separately and drifting silently.
Paccurate centralizes all packing logic in the PCS. Rules, carton configurations, and rate tables are built once and deployed across every DC and partner location immediately. Each site gets packing behavior adapted to its capabilities so the standard is the same everywhere. Or, if each site has a different requirement, configurations can be adjusted to meet your business needs.
A global apparel brand operating more than ten distribution centers across four continents, through a mix of self-operated facilities and 3PL partners, runs one packing standard across all of them. In some locations, they’re trying to increase the efficiency of their picking automation, while in others they are focused on reducing store putaway labor. There are zero IT tickets to make a configuration change across the network.
As networks grow, so does the operational overhead of managing packing at each node: new WMS integrations, per-site rule maintenance, IT backlogs every time something needs to change. The Packing Control System sits above all of it.
Whichever system fields a packing question, either the WMS or the OMS at order import, the PCS answers with a decision already priced against the full cost picture: rate cards, material costs, item rules, and downstream labor. There’s no need to rearchitect existing systems or manage a per-site configuration. It’s one decision layer for any number of buildings.
