What “volume tier not applied” means
The invoice quantity being priced may differ from the metric that selects the tier. For example, monthly orders might select a pick rate that then applies to individual items. Store both quantities separately.
1. Identify the metric and its scope
Write the metric exactly as the agreement defines it: orders per calendar month, fulfilled units per week, customer-service calls per month, average items per order, or another measure. Then resolve:
- Which facilities, channels, legal entities, and service types contribute to the metric.
- Whether cancelled orders, returns, test orders, wholesale shipments, or split shipments are included.
- Which event date assigns activity to the period.
- Whether provider reports or merchant operational records are the contract source of truth.
- How boundary values are treated at the lower and upper ends of each tier.
2. Distinguish bracket-select from graduated pricing
Under bracket-select pricing, one rate selected by total period volume applies to every eligible unit. Under graduated or marginal pricing, each slice of volume receives its own rate. The formulas differ materially.
expected charge = eligible billed quantity × rate selected by complete-period metricDo not infer the mechanic from how a table looks. Read the surrounding terms and examples. The current local Auditario rule model supports bracket-select ladders, not graduated or marginal tiers.
3. Confirm the full billing period
A weekly or partial-month invoice usually cannot establish a monthly tier by itself. Collect every sibling invoice and adjustment that contributes to the period, or use the contract-named activity report. Watch for late postings and events that straddle the boundary.
The corpus also showed why summary grain blocks line-level conclusions: a period total cannot safely answer a per-order question without the supporting detail. See the complete-period regression note.
4. Select the bracket, then price the charge
- Aggregate the supported metric over the complete contract period and scope.
- Select the bracket using its inclusive and exclusive boundaries.
- Confirm the rate’s effective date and any amendment.
- Apply the selected rate to the contract-defined eligible billed quantity.
- Compare the result with the invoice and preserve exact arithmetic.
Invented rates, quantities, references and amounts; not a customer record or provider allegation.
An invented bracket-select ladder sets 0–499 monthly orders at $2.50 and 500–999 at $2.20. A complete invented monthly statement supports 600 eligible orders but bills $2.50: billed $1,500; expected $1,320; $180 review candidate.
The $180 is not automatically owed, claimable, submitted, credited, or recovered. A graduated ladder, excluded order class, incomplete month, amendment, or minimum could change the calculation.
Boundary and unpublished-tier cases
Record whether a boundary such as 500 belongs to the lower or upper bracket. If a high-volume rate says “custom” or “contact us,” there is no source-backed numeric value to infer. That part of the charge remains a coverage gap until the negotiated rate is obtained.
Evidence required
- The full tier ladder, mechanic, metric, period, scope, boundaries, effective dates, and source citation.
- Complete activity evidence for the period, including sibling invoices or the contract-named operational report.
- The invoice line, eligible priced quantity, billed rate, amount, and source coordinate.
- Amendments, concessions, minimums, allowances, and excluded activity definitions.
- Dispute-window clause and supported anchor date.
Use the 3PL rate-card guide to normalize the ladder and the audit checklist to preserve period evidence.
How Auditario treats this check
Volume-tier results have a review-required publication ceiling. Period metrics need complete period evidence or explicit sibling-invoice state, and bracket semantics must be source-bound. An isolated invoice is not enough for a safe monthly conclusion.
Auditario is prelaunch: secure document intake is not open, there are 0 certified publication cells, and $0 is presently claimable. Read the methodology, inspect the synthetic sample, and see the current product status.
