Fill rate is the completeness indicator that measures what share of demand —lines, units, or orders— is satisfied with available inventory or flow in a period. By itself it does not include punctuality: that belongs to OTD (On Time Delivery) and the AND of OTIF (On Time In Full).

If the dashboard celebrates 97% fill rate and 96% on-time “averaged,” the customer who receives late or incomplete does not celebrate: they live the AND. This guide covers formula, variants, the matrix vs OTIF/OTD, and Mexico context from the 4th National Logistics Indicators Study 2026.

What fill rate is (usable answer)

In Mexican operations, fill rate answers: of what the customer ordered in the period, what percentage was fulfilled complete under the In Full rule you published? It is a key performance indicator (KPI) of availability and fulfillment — inventory, picking, and partials policy — not an appointment clock.

Fill rate (%) = (Demand fulfilled ÷ Demand requested) × 100
Demand fulfilled
Pieces, lines, or orders that met the In Full rule in the period.
Demand requested
The full universe (include hard backorders; do not pull them from the denominator).
Unit
Customer order, line, or case. Declare it on the report.

Example:100 orders, 97 with all lines complete to order fill 97%. If you measure lines, you might see 99% because failures concentrate in a few orders. The “prettier” number is not the most useful for the customer.

Line fill, order fill, and case fill

Three common variants. Picking the wrong unit (or changing it by month) is the fastest way to make plant or 3PL reports incomparable.

Order fill

What it counts: 100% complete order

When it helps: Customer scorecard / SLA

Risk: Stricter; hurts more

Line fill

What it counts: Lines fulfilled / lines ordered

When it helps: Inventory and picking diagnosis

Risk: Hides “almost” broken orders

Case / unit fill

What it counts: Cases or pieces fulfilled

When it helps: DC and retail by volume

Risk: Not equal to a perfect order

Put the unit in the KPI title. “Fill rate 98%” with no unit is an empty number.

Fill rate vs OTIF vs OTD vs perfect order

Each metric has a job. Averaging them is the OR error that inflates perceived service by 5–15 points in real operations.

Fill rate

Measures: Completeness (In Full)

Ignores if used alone: Late delivery

Typical use: Inventory / fulfillment

OTD

Measures: Punctuality (On Time)

Ignores if used alone: Incomplete order

Typical use: Appointments, network, transport

OTIF

Measures: On time AND complete (AND)

Ignores if used alone: Damage / docs (by definition)

Typical use: Customer scorecard

Perfect order

Measures: OTIF + damage-free + accurate docs (typical definition)

Ignores if used alone:

Typical use: Frictionless service

Averaging OTD and fill rate does not produce OTIF. The customer lives the AND.

Fill rate in Mexico (National Study 2026)

The 4th National Logistics Indicators Study 2026, led by #SoyLogístico Asociación, LDM, and EGADE Business School at Tecnológico de Monterrey (with Secretaría de Economía participating in this edition), consolidates data from 160+ companies (2023–2025). In study coverage, customer-delivery fill rate ranks among the strongest indicators: about ~93% average in the sample.

Press coverage of the same study places most sectors in a healthy band of roughly 93–96%, and highlights the gap between leaders (very high compliance, often cited near or above 99%) and laggards (much lower reported floors, around ~65% in some readings). Treat leaders vs laggards as a press hedge: always calibrate to your vertical, unit of measure, and service-level agreement (SLA).

For the full distribution board (service, cost, control, and cash), use the hub distribution KPIs — logistics Mexico.

How to measure fill rate without gaming

Use the same unit for fill rate, OTD, and OTIF. Publish the AND. Without an honest denominator and evidence, the percentage is decoration.

  1. Choose unit

    Order, line, or case

  2. Define In Full

    100% + SKU + condition

  3. Lock On Time

    Window and event

  4. Compute three

    Fill, OTD, OTIF

  5. Segment causes

    Stock vs transport

Three honest numbers beat a gamed average.

Mistakes that fool the board

These failures produce high KPIs and angry customers. Fix the definition before buying another dashboard.

Raise fill rate without breaking OTIF

Inventory, wave cut-offs, and picking improve In Full. Realistic appointments, lead-time buffer, and in-transit alerts improve On Time. If you only push fill rate with late partials, OTIF falls even when the spreadsheet “looks green.”

Typical tools: stock policies, fast tendering when capacity is missing, and early exception tracking. The hybrid stack is in TMS vs OCL agents.

OCL and the trip file

OCL Cargo is an autonomous transportation management system (TMS) with agents: it unifies milestones, proof of delivery (POD), and documents in one trip file so fill rate, OTD, and OTIF can be defended — not invented in Excel. It coexists with your system of record; your team decides exceptions. When applicable, OCL can stamp invoices and Carta Porte. It does not run your warehouse management system (WMS) or guarantee a fill rate.

Key takeaways6 points
  1. Fill rate = (demand fulfilled ÷ demand requested) × 100: completeness, not punctuality.
  2. OTIF requires On Time AND In Full; fill rate is usually only the In Full side. Averaging OTD and fill rate is not OTIF.
  3. 4th National Study 2026 (#SoyLogístico / LDM / EGADE): customer-delivery fill rate ~93% sample average; sectors ~93–96% — calibrate to your operation.
  4. Always declare the unit (order, line, case). Mixing units makes plant reports incomparable.
  5. Raising fill rate with late partials kills OTIF. Inventory improves IF; appointments and tracking improve OT.
  6. Distribution board: distribution KPIs.

Is your fill rate hiding a weak OTIF?

In a diagnostic we review unit of measure, real AND, and delivery evidence so the KPI matches what the customer lives.
