The 9 types of logistics: the operational truth of each

Not all logistics is the same

In Mexico, “logistics” is used for almost everything: the truck, the DC, the Laredo crossing, the last-mile courier, and the 3PL that “handles it.” The problem is not vocabulary: it is that each type destroys (or protects) margin through a different mechanism.

Inbound is not measured in freight pesos: it is measured in line stops when the supplier misses OTIF (On Time In Full). Outbound is punished when the unit bounces at the appointment. Cold chain does not forgive a thermal excursion. Foreign trade does not forgive a file without substance before Mexico’s tax authority (SAT).

If your dashboard only shows “freight cost / shipment,” you are averaging nine realities. The first operating step is to name the type, assign the right KPI, and define which evidence closes payment or dispute.

Matrix: 9 types × truth × KPI × leak

Use this table in the operations and finance meeting. If a type has no owner, KPI, or cost center, the leak is already normalized.

Inbound and outbound: stops vs appointments

Inbound is the flow from the supplier into your plant or DC. Freight can look “cheap” and still be ruinous: if material is not on time and complete, the line stops. That is why the KPI is not cost per km — it is supplier OTIF.

What is measured poorly: an inbound rate card not tied to appointments, dock windows, and goods acceptance. What is measured well: OTIF by supplier, dock wait minutes, and root cause of shortages (supplier, carrier, or receiving).

Outbound is the flow to the customer. Here the most expensive freight is almost never the base rate: it is the trip that bounces at the appointment, gets rescheduled, and wrecks customer OTIF / fill rate. A DC that gives you one hour and rejects a late arrival turns “freight savings” into penalties and re-delivery.

Both flows share appointment discipline and delivery evidence, but the owner of the pain changes: inbound hurts production; outbound hurts the customer and commercial margin. Go deeper on the control object in what is a shipment.

Reverse logistics: the unbudgeted return

Returns — product returns, pickups, packaging, damaged goods — usually cost more than the outbound leg: thinner routes, improvised appointments, damaged merchandise, and weak rate negotiation. And almost nobody budgets them as their own line.

KPI: cost per return (and, if applicable, % of product recoverability). If reverse lives inside “general freight,” the committee never raises the priority: cost dilutes until e-commerce volume or DC rejects make it visible.

Minimum playbook: a separate cost center, return authorization with photo/evidence, and matching the return invoice to the original order. Without that, you pay for the trip twice and the dispute once.

Outsourced (3PL/4PL): execute, never cede evidence

A 3PL (third-party logistics) executes warehouse, transport, or both. A 4PL (fourth-party logistics) integrates and orchestrates multiple providers. In both cases the operational truth is the same: you delegate execution; never the evidence.

KPI: margin vs rate — what they charge, what they deliver, and what you can prove. If the 3PL invoices and you pay without matching rate + documents + GPS + proof of delivery (POD), you bought opacity with an “outsourcing” label.

Warehouse: what does not turn pays rent

The warehouse is not “space”: it is immobilized capital plus picking, packing, and dock labor. What does not turn pays rent every day — in square meters, in obsolescence, and in errors that later become customer claims.

KPI: turns and accuracy (inventory and picking). A warehouse management system (WMS) without cycle-count discipline only digitizes disorder. The handoff to freight matters: a well-documented shipment is born at the dock, not in the carrier’s PDF.

Freight transport: the leak is in accessorials

This is where many shippers learn the hard way. The rate is contracted per trip (or per km / weight). The leak is in accessorials: detention, lumper, deadhead, border delays, re-deliveries. The control KPI cannot be only “average rate”; you need cost per km (or per shipment) all-in — base + fuel + extras — and line-by-line matching before you pay.

Without 100% coverage, accounts payable releases invoices that “look reasonable” while 8–15% of the all-in hides in poorly evidenced charges. That is why the OCL pattern when auditing the full pilot universe is recovering 5–7% of spend.

Foreign trade: no documentary substance, no mercy

On the Mexico–US corridor, the crossing is not just a GPS pin on the bridge. It is pedimento, value, origin, Carta Porte, and a file that survives review. Without documentary substance, SAT does not forgive — and the cost shows up as delay, storage, penalty, or lost tariff preference.

KPI: crossing time (and % of releases on the first documented attempt). A tower that only watches ETA without tying XML, packing list, and transfer proof is flying blind.

Core transport-side piece: what is Carta Porte. OCL verifies on the buyer side; it is and can stamp CFDI.

Cold chain: one excursion destroys the lot

In food, pharma, or sensitive chemicals, a thermal excursion is not “discounted” like an accessorial: it destroys the lot, triggers DC rejection, or opens a recall. The KPI is not cost per km — it is continuous temperature with a log tied to the shipment ID.

If thermal evidence lives in the carrier portal and the POD lives in WhatsApp, you already lost the dispute. Delivery reconciliation and documented custody are the standard when the product does not tolerate averages.

Last mile: the leg that eats the margin

The last leg — from DC or hub to the home or store — can take nearly half the shipment cost. The KPI that matters is first-attempt delivery: every retry burns fuel, courier time, and the customer promise.

Badly booked windows, incomplete addresses, and “leave it with the neighbor” without evidence turn last mile into a margin hole. Definition and limits: what is last mile.

How to audit cost by type

You do not need a two-year project. You need an honest inventory: which types you run, who owns them, which KPI you watch today, and which evidence accounts payable requires before releasing payment.

Measure freight and evidence across types

The nine types do not require nine systems on day one. They require one file per trip and agents that match the repeatable work before accounts payable releases payment. OCL Cargo operates as an autonomous TMS with computer use: it works on portals and screens, coexists with your TMS or ERP, and escalates exceptions to your team.

Without replacing your current tools on day one: pilot on one corridor, 100% coverage of the flow, typical recovery pattern 5–7%. You decide with a file; OCL is not a PAC.
