3PL Rate Card Setup — How to Structure Per-Client Pricing

Rate cards are the contract between you and your client expressed as a structured pricing document. Every 3PL client has slightly different commercial terms — storage rates, handling tiers, packaging requirements, special-service charges. A flat "one rate card for everyone" approach falls apart the moment you sign your second client.

Per-client rate cards prevent two failure modes: (1) under-charging because you forgot the special terms negotiated with one customer, and (2) over-charging because the rate card doesn't reflect a discount or promo you agreed to.

Three common storage rate structures, in order of complexity:

Flat per-pallet, per-month. Simplest model. $X per pallet per month, accrued daily. Works for clients with stable inventory profiles.

Tiered by volume. First 100 pallets at one rate, 101-500 at a lower rate, 500+ at the lowest rate. Encourages clients to consolidate at your warehouse — good for capacity utilization.

Tiered by age. Inventory under 30 days at one rate, 31-90 at a higher rate (encourages turnover), 91+ at a much higher rate (encourages disposal or relocation). Protects you from dead inventory occupying capacity.

Many 3PLs combine age and volume tiers. The complexity increases, but so does the precision of pricing.

Handling rates should be enumerated explicitly per billable event. The rate card needs answers for:

Receiving: per carton, per pallet, per line item, or per inbound receipt? Different clients prefer different models — and your operational cost may not match what the client wants to be billed on.

Picking: per pick, per line, per unit, or per order? Per-order is simplest but punishes you on small-quantity orders. Per-line balances complexity with fairness.

Packing: usually rolled into picking, but can be separated if you charge for special packaging materials.

Special services: kitting, labeling, photo verification, quality inspection — billed per occurrence with rates specific to the service.

Rate cards change over time — annual escalations, mid-contract renegotiations, promo periods. The rate card data structure must support effective-date changes, not just current rates.

When you bill April activity, you need to bill at the rates that were effective in April — not the rates that just changed in May. This sounds obvious; it is consistently the most common bug in 3PL billing software.

Promotional discounts, first-month-free incentives, and volume-commitment discounts are overlays on top of the base rate card — not replacements for the underlying rates. The rate card stays the same; the overlay applies for the promo period and falls off automatically.

The reason this matters: when the promo expires, the system should automatically bill at full rate. Without overlay structure, 3PLs forget to remove the promo discount and continue billing at the discounted rate indefinitely.
