Home Depot On-Time Chargeback: MABD and the 90% Threshold

Executive Summary & Quick Answer

Executive summary: On-time compliance at Home Depot is a threshold metric, not a per-event fine. The requirement is roughly 90% on-time accuracy: shipments arrive on the correct date, by the must-arrive-by date (MABD). Fall below that threshold, and the penalty ties to the late shipment — per the record, 10% of items not shipped for the late shipment. The management consequence is subtle: you don't defend individual deliveries, you defend a percentage. A supplier running at 97% can absorb a bad week; a supplier hovering at 91% is one carrier failure away from penalties. That's why the operating posture is scorecard-first — watch the on-time metric in the Supplier Hub, and manage lead-time buffers so the average never drifts toward the line.

Quick answer: Home Depot's on-time chargeback applies when delivery performance falls below roughly 90% on-time accuracy — shipments must arrive on the correct date, by the must-arrive-by date (MABD). Falling below the threshold triggers a penalty tied to the late shipment: 10% of items not shipped. Buffered lead times and scorecard monitoring prevent it.

Deep Dive: A Threshold, Not a Stopwatch

Every Home Depot PO carries a must-arrive-by date. Arrival on the correct date, by the MABD, counts as on-time; the requirement is to keep the on-time rate at roughly 90% or better. The penalty doesn't fire per late truck — it fires when your rate falls below the threshold, and it ties to the late shipment: 10% of items not shipped.

The lateness budget is the useful way to think about it:

 on-time rate                          your position
 100% ┤████████████████████  safe — budget to absorb bad weeks
  95% ┤██████████████        cushioned
  90% ┤█████████ ─────────── THE LINE ───────────
  <90%┤████  penalties tie to late shipments

At ~90%, roughly one shipment in ten can be late before penalties engage. That budget gets spent by three clocks stacking up against the MABD:

Clock	Owned by	Typical failure
Production/fulfillment	You	Order ready after the ship-by date already passed
Carrier pickup	Carrier (routed via Home Depot's TMS on collect)	Missed or rolled pickups
Transit	Carrier/network	Delays that a zero-buffer plan can't absorb

The trap is planning each shipment to just make its MABD. With zero buffer, ordinary variance — one missed pickup, one weather day — converts directly into late arrivals, and a few clustered late arrivals can drag a quarter's rate through the floor.

Business & Financial Impact

• Penalty: 10% of items not shipped for the late shipment, applied when performance falls below the ~90% on-time threshold — a value-linked penalty, unlike the flat ASN fees, so big late orders cost proportionally more.
• Threshold dynamics cut both ways: above 90%, late shipments cost nothing directly; below it, the penalty regime engages. Two suppliers with one bad week each can see completely different bills depending on where their baseline rate sat.
• Correlated failures are the killer: lateness clusters — a port delay, a carrier network problem, a plant issue hits many POs in the same window. The threshold protects against noise, not against clusters.
• Beyond the fine: on-time performance is scorecard data in the Supplier Hub. A deteriorating score is a relationship cost even in weeks when no penalty posts.

Root Causes (Ranked)

1. Delivery after the must-arrive-by date (MABD) — the direct trigger, whatever pushed it: the truck arrived past the date the PO required.
2. Missed carrier pickup — freight ready, carrier absent. The shipment starts its transit late through no fault of the dock, but the MABD doesn't move.
3. Production or fulfillment delays — the order wasn't ready by its ship-by date, so no carrier performance could save the arrival. The furthest-upstream cause and the one only planning can fix.

Step-by-Step Prevention Workflow

1. Work backward from the MABD on every PO. MABD minus transit time minus a buffer = ship-by date; ship-by minus fulfillment time = start-by date. If today is past start-by at order review, escalate immediately — that PO is already at risk.
2. Build lead-time buffers into planning. Zero-buffer plans convert ordinary variance straight into late arrivals. Size the buffer per lane from actual transit-time history, not the carrier's published standard.
3. Treat pickup as a monitored event. A missed pickup silently burns your buffer. Alert the same day, rebook through Home Depot's TMS (on collect freight), and re-check the arrival math against the MABD.
4. Watch the scorecard in the Supplier Hub. Your on-time rate is the actual managed variable. Review it on a cadence, with an internal floor above Home Depot's (say, act at 93%) so drift gets attention while there's still budget.
5. Escalate at-risk POs before they're late. A PO flagged at start-by or ship-by can often be expedited, split, or re-planned. A PO flagged at arrival is just a statistic.

On-Time vs Related Home Depot Violations

Violation	Trigger	Typical fine
On-time (MABD)	On-time rate below ~90%; penalty tied to the late shipment	10% of items not shipped
Routing violation	Collect freight off-TMS or unauthorized carrier	$250 per violation
Late ASN	856 transmitted outside the 24-hour/pre-arrival window	$250 per late ASN

The three are one timeline: routing determines the plan, on-time measures the freight against it, and the ASN clock runs alongside — a shipment scrambling to make its MABD is exactly the shipment whose ASN gets sent late.

Supplier Checklist

• Every PO backward-scheduled from its MABD: start-by, ship-by, pickup dates
• Lane-level buffers sized from actual transit history
• Missed pickups alerted same-day and rebooked through Home Depot's TMS (collect)
• On-time scorecard reviewed in the Supplier Hub on a fixed cadence
• Internal action floor set above 90% (e.g., investigate at 93%)
• At-risk POs escalated at the milestone miss, not at arrival

FAQs

What is Home Depot's on-time delivery chargeback? A penalty applied when on-time performance falls below roughly 90% — shipments must arrive on the correct date, by the must-arrive-by date (MABD). The penalty ties to the late shipment: 10% of items not shipped.

What is the MABD? The must-arrive-by date on the PO — the date the shipment must reach Home Depot. Arrival by the MABD, on the correct date, counts as on-time.

Does one late shipment trigger a fine? The requirement is threshold-based: roughly 90% on-time accuracy. The penalty regime engages when performance falls below that line, with the penalty tied to the late shipment.

The carrier missed the pickup — are we still penalized? The MABD doesn't move for a missed pickup, which is why pickup confirmation and same-day rebooking matter. On collect freight, rebook through Home Depot's TMS rather than substituting a carrier, which is its own violation.

Where do we track our on-time performance? On the on-time scorecard in Home Depot's Supplier Hub. Set an internal floor above 90% so drift triggers action before penalties do.
