Why high-volume teams choose Nexli
Combine real-time carrier rates, ML packing guidance, and auditable business rules. Nexli acts as the shipping brain that every commerce, ERP, and 3PL team can trust.
Parallel API calls with normalization, surcharge breakdowns, and graceful degradation when a carrier times out.
Historical packing trust engine keeps learning from live shipments so math respects real warehouse wins.
Point-and-click logic with AND/OR groups, prioritized actions, and complete audit trails for finance and ops teams.
Nexli evaluates every shipment with a four-level match: exact order twins, dimension ranges, similar line items, and pattern-based heuristics. Each recommendation ships with a trust score (0–100) plus the reason why.
Runs "minimize boxes", "maximize utilization", and "balanced" strategies every time—then scores them.

Prioritize the "free" cartons brands send you, handle partial remainders, and respect weight ceilings automatically.
The most flexible shipping rules engine
Operations teams replace fragile spreadsheets with auditable automation in five minutes.
Weight tiers, order totals, carrier/service, destination zones, customer tags, and custom metadata.
Apply margins, surcharges, handling fees, caps, or force/block specific services—each with priority numbers.
Engine evaluates in order and surfaces which rule fired so finance, CX, and 3PL clients see the math.
Every rule run is logged with before/after values so you can debug pricing in seconds.
Bring your own carrier credentials, test requests locally, and push to production without waiting on professional services.
