Tolling looks simple on paper. The customer owns and supplies the raw materials, the toller converts them into product using its own equipment and people, and the customer pays a processing fee. No sale of goods changes hands at the front end, and the customer keeps title to the material from drum to finished lot.
In practice, a toll manufacturing agreement creates one of the harder tracking problems in the supply chain. The customer has inventory it owns but does not hold, at a site it does not run, being transformed by a process it does not control. Every kilogram that goes in should come back out as product, by-product, waste or an agreed allowance for loss. When nobody reconciles those numbers against the contract, value leaks quietly.
This datasheet covers what a toll manufacturing agreement typically contains, where supply chain and contract manufacturing teams lose visibility, and how Aavenir tracks each term as a live obligation rather than a clause in a PDF. It is written for supply chain, contract manufacturing and procurement teams at chemicals and specialty materials companies that run several tolling relationships at once.
What a toll manufacturing agreement contains
Chemical and specialty materials tolling agreements vary by process, but the terms that matter for tracking fall into a consistent set. These five carry most of the financial exposure.
- Title and risk of loss, confirmation that the customer retains title to supplied materials, work in process and finished goods, and a clear rule on when risk of loss sits with the toller.
- Yield and loss allowances, the expected conversion yield, the permitted process loss and the remedy when actual yield falls below the allowance.
- Material reconciliation, the cadence and method for reconciling materials received, consumed, produced and on hand, including physical counts.
- Specifications and quality, product specifications, certificates of analysis, sampling, retained samples and the process for rejecting off-spec batches.
- Tolling fee and adjustments, the per-unit or per-batch fee, minimum run charges, and adjustments for utilities, energy or labor costs.
Around these sit capacity reservation and minimum runs, by-product and waste ownership and disposal, insurance for customer-owned inventory, audit rights, and termination terms that govern the return of materials. Each of these creates a dated or measurable duty for one party or the other.
Material held at a toller is still on your balance sheet. If yield loss goes unreconciled for a few quarters, the gap between book inventory and physical inventory widens, and by the time a count exposes it, the contract window to claim against the toller may have closed.
Why tolling terms slip after signature
Most toll manufacturing agreements are negotiated carefully and then filed. The operational team works from batch records and emails, finance works from inventory reports, and the contract terms that connect the two are rarely consulted until a dispute. Staff turnover at either site makes it worse, because the people who negotiated the yield allowance are often not the people running the campaigns.
- Yield loss is not compared to the allowance. Batch yields are recorded, but nobody checks cumulative loss against the contracted allowance, so claims for excess loss are never raised.
- Reconciliations run late or not at all. A monthly or quarterly reconciliation clause only protects the customer if it happens on schedule and discrepancies are escalated.
- Fee adjustments are applied without checking. Energy or utility surcharges get invoiced, and AP pays them without confirming the index, the trigger or the cap in the agreement.
- By-products and waste drift. Ownership of saleable by-products and responsibility for hazardous waste disposal are defined in the contract but not tracked against actual volumes and manifests.
- Insurance certificates lapse. The toller must insure customer-owned inventory, but expired certificates go unnoticed until a loss event.
How to build tolling obligation tracking
Step 1, Centralize every tolling agreement
Pull every toll manufacturing agreement, amendment, quality agreement and pricing schedule into one repository. Tolling terms are often split across a master agreement, a product schedule and a separate quality agreement, so link them to the same counterparty and product. Tag each agreement by site, product family and business unit so owners are obvious.
Step 2, Extract the commercial and material terms
Use AI extraction to pull yield targets, loss allowances, reconciliation cadence, fee structures, minimum run commitments, by-product rules and insurance requirements into structured fields. Review the extracted values with the contract manufacturing manager, since yield allowances are sometimes expressed per batch, per campaign or per year. Capture quality terms too, including certificate of analysis requirements and the window for rejecting off-spec batches. Structured data is what makes the rest of the program work.
Step 3, Turn terms into tracked obligations
Each extracted term becomes an obligation with an owner, a due date or trigger, and an evidence requirement. Reconciliation becomes a recurring task. Insurance becomes an expiry alert. Capacity reservation becomes a notice deadline. Our manufacturing obligation management datasheet describes how these obligations are assigned and escalated.
Step 4, Connect yield and fee data to the contract
Bring batch yields, material reconciliations and toller invoices into the obligation record. Compare cumulative loss to the allowance and fee adjustments to the contracted mechanism. Flag breaches automatically so the team can raise claims while the contract window is still open. The patterns in our value leakage checklist apply directly to tolling fees and credits.
Step 5, Plan renewals and exits early
Tolling relationships are hard to replace quickly, because qualifying a new toller takes time. Track renewal and termination notice dates well ahead of the deadline, and keep return-of-materials and final reconciliation obligations ready so an exit does not strand inventory or leave waste liabilities unresolved. Confirm who pays freight for returned materials, how retained samples and quality records are handed over, and when the final reconciliation must close. Those details are easy to negotiate at signature and painful to argue about during a wind-down.

Aavenir extracts yield, reconciliation, fee and insurance terms and tracks them against real batch and invoice data.
What Aavenir tracks for toll manufacturing agreements
Aavenir CLM and obligation management, standalone or native on ServiceNow, hold the tolling agreement, its schedules and its quality agreement together. AI extraction pulls the yield, fee, reconciliation and insurance terms into fields. Obligations are assigned to supply chain, quality, finance and EHS owners with reminders and escalations. Dashboards show cumulative yield against allowance, overdue reconciliations and upcoming notice dates across every toller, so contract manufacturing managers can manage the portfolio instead of chasing individual files. Teams commonly find that the first full reconciliation against contract terms surfaces claims nobody had raised.
Toll manufacturing agreement field map
This is the field map Aavenir uses as a starting point for tolling agreements. Teams adapt it to their process chemistry and site structure.
| Field | What the agreement defines | How it is tracked | Owner |
|---|---|---|---|
| Title and risk of loss | Customer title to supplied materials, work in process and product, and when risk transfers | Inventory held per toller, insurance certificate expiry alerts | Supply chain, risk |
| Yield and loss allowance | Expected yield, permitted process loss, remedy for excess loss | Cumulative loss vs. allowance per campaign, breach flags | Contract manufacturing |
| Material reconciliation | Cadence, method, physical counts, discrepancy resolution | Recurring task, overdue alerts, variance log | Supply chain, finance |
| Tolling fee and minimums | Per-unit or batch fee, minimum runs, capacity reservation, cost adjustments | Invoice check against fee schedule, minimum run and notice dates | Procurement, AP |
| By-products, waste and exit | Ownership, disposal duties, audit rights, return of materials on termination | Disposal evidence, audit schedule, renewal and termination notice dates | EHS, legal |
A toll manufacturing agreement is only as good as the reconciliation behind it. When yield allowances, fees, insurance and exit terms sit in structured fields with owners and deadlines, supply teams can see what they own at every toller, catch excess loss while it is still claimable, and renew or exit on their own timeline.
