Three contract structures dominate Southern timber sales: lump-sum stumpage, pay-as-cut (per ton), and negotiated stumpage. They are not interchangeable. Each shifts the price, volume, and execution risk between landowner and buyer in a different way, and the right choice depends on the stand, the market, and the landowner's tolerance for downside.
What "stumpage" means
Stumpage is the price paid for standing timber — the value of the tree on the stump, before the logger and trucker take their cut. Every Southern timber sale, no matter how it's structured, is ultimately a stumpage sale. The difference is whether you fix the total price up front (lump sum), let it move with what's actually cut and scaled (per ton), or negotiate a flat per-acre or per-tract number outside the bid market.
Lump-sum sales
In a lump-sum sale, the buyer pays a single fixed price for all merchantable timber inside the marked boundaries, regardless of how much actually comes off the tract. Payment is typically made at contract signing or in scheduled installments tied to harvest start.
Who carries the risk: the buyer. They have the cruise data, but if the cruise was light or the wood is harder to access than expected, they eat the difference.
Who benefits: the landowner who wants certainty — a known check, on a known date, with no exposure to weather delays, mill quotas, or a buyer's poor execution. Lump sum is also cleaner for estate, divorce, and partition cases where a defensible single number matters.
What it requires: a credible cruise. Buyers will not bid aggressively into a lump-sum sale without one. The cruise is what lets them price risk.
Per-ton (pay-as-cut) sales
In a per-ton sale, the contract sets a price per ton for each product class — pine pulpwood, CNS, pine sawtimber, hardwood pulp, hardwood sawlogs, poles. The landowner is paid based on actual mill scale tickets as the wood is delivered.
Who carries the risk: the landowner. If volumes come in light, the check is light. If markets soften between bid and harvest, the buyer is still buying — but only at the original rates locked into the contract.
Who benefits: landowners with very dense stands where buyers are conservative on volume, tracts where access or terrain make volume hard to estimate, or markets where one product class (poles, hardwood sawlogs) is expected to be exceptional. Per-ton also tends to attract more bidders on marginal tracts because buyers aren't betting on the cruise.
What it requires: tight oversight of scale tickets, mill destinations, and product grading. Without it, the landowner has no way to verify what's actually being paid for.
Negotiated stumpage
A negotiated sale is a price agreed directly with one buyer, outside a competitive bid. It is the fastest path to a check and almost always the lowest price the tract would have brought. The buyer who calls first gets to set the anchor, and the landowner has no benchmark for what the open market would have paid.
Negotiated sales have a place — very small lots, salvage after a storm when speed matters more than price, or thinning a private inholding for a neighbor — but they should be the exception, not the default. (See how a sealed-bid timber sale works for the competitive alternative.)
How to choose
Three questions resolve most decisions:
- How confident is the cruise? Strong cruise on a clean tract → lump sum often wins. Heavy stocking with high variance → per-ton may attract more bids.
- What's the landowner's risk tolerance? Estate, divorce, fixed-income retiree → lump sum. Patient landowner with appetite for upside and capacity to audit scale tickets → per ton.
- What is the market saying? When sawtimber stumpage is firm and CNS is soft, the relative weight of each product class can tilt one structure over the other. A current timber price update is part of every sale recommendation.
Hybrid structures
Many of the best sales aren't pure. A lump-sum base price for pulpwood and CNS with a per-ton premium for poles. A lump sum for a thinning with a per-ton overage clause if volumes exceed the cruise. A pay-as-cut sale with a guaranteed minimum. The right structure isn't a category — it's whatever puts the most defensible dollars on the closing statement while keeping the contract enforceable.
The audit problem (and how to fix it)
The hidden risk in per-ton sales is product-class misgrading at the mill. Pine sawtimber graded as CNS, or CNS graded as pulpwood, can quietly cost the landowner significant money on a large tract. The fix is straightforward: scale-ticket audit against mill receipts, periodic load checks at the truck, and a contract that requires destination disclosure and right-of-audit. None of this is exotic — it's routine work for a forester representing the landowner.
The takeaway
Lump sum, per ton, and negotiated stumpage are tools, not religions. The right tool depends on the cruise, the tract, the market, and the landowner's goals. Picking the right one — and pairing it with a contract that holds up — is what a consulting forester is hired to do.
