Evaluate the 3PL's location relative to major highways and rail; warehouse configuration (racking, clear height, temperature control); tech stack (WMS, integrations, EDI/API); SLA performance (OTD, picking accuracy); and scalability for seasonal peaks. Also verify carrier contracts, cross-dock capability, and visibility tools for omnichannel orders.

Choosing a Sivas-based 3PL often shortens transit to central and eastern Turkey while providing lower facility costs. For western or coastal destinations, transit may be longer, so compare lane-specific lead times and per-shipment rates. Use lane modeling to quantify carrier access, fuel surcharges, and landed cost implications for your network.

Require modular pick-and-pack zones, returns processing workflows, reverse-logistics staging, and temperature-controlled space if needed. Confirm WMS features for split orders, batch picking, and real-time inventory sync. Define KPIs (pick accuracy, returns processing time, inventory days) and SLAs tied to penalties and remediation pathways.
