Large Package Mix and How It Changes Your Revenue

Two settlement weeks can carry the same number of packages and pay noticeably different amounts — with every rate on both statements exactly matching your contract. The usual culprit is mix: what kinds of packages made up the volume. Large and oversize packages are the most visible version of this, because they change both sides of the ledger — what the work pays and what it costs you to perform. This article is about seeing mix clearly so it stops getting misdiagnosed as something else.

What it is

Not every package settles the same. Depending on your agreement, volume in different categories — standard, e-commerce, larger or harder-to-handle packages — can settle under different charge types and rates on your Schedule C. "Mix" is simply the proportion of each category in a given week's volume. When the proportions move, your blended revenue per package moves with them, no rate change required.

The two-sided effect

• Revenue side. If categories pay differently, then a shift toward one changes what an average package earns. The direction depends entirely on your rate card — which is why generalizations from other contractors ("big boxes are great" / "big boxes kill you") may be true for their agreement and false for yours.
• Cost side. Large packages consume van capacity, load time, and driver effort disproportionately. A truck that cubes out on furniture makes fewer stops per trip; a route heavy on bulky items runs slower days. Even if a category's revenue is favorable, its margin depends on these operational costs — and margin, not revenue, is the number that pays you.

Mix shift masquerading as other problems

The reason to track mix explicitly is diagnostic. A drifting mix shows up indirectly as symptoms that look like other problems: revenue per package sliding ("did a rate change?" — no), labor hours creeping ("are drivers slowing down?" — no), a week paying light against its package count ("is the settlement short?" — no). Checking the mix first is the cheapest way to rule these in or out before escalating. If mix is stable and revenue per package still moved, then you have something worth checking line by line against the rate card.

What to check

• Compute your weekly category shares from the settlement's units per charge type — each category's units as a share of total packages, tracked week over week, per CSA.
• Pair revenue-per-package moves with mix moves.Before treating a change as a rate question, check whether the mix moved the same week. Most of the time, it did.
• Watch for durable shifts, not single weeks. One bulky week is noise. A category share that trends for several consecutive weeks is territory change — a new shipper, a new retail pattern — and worth factoring into fleet and staffing decisions before it forces them.
• Note the operational fit. If large-package share is durably rising, the honest follow-up questions are about van sizing and route loading, not just the settlement.

Tracking mix without the manual work

Route Impact records each week's revenue and volume mix from the uploaded settlement and charts category shares over time, so a durable shift is visible as a trend instead of a vague feeling that weeks "pay less than they used to." Rate checks against your stored Schedule C run alongside, so the mix-versus-rate question answers itself — and anything that genuinely doesn't reconcile is flagged for your review with the evidence attached. The same analysis works in a spreadsheet with units-per-charge-type columns; what matters is that somebody actually maintains it weekly.
