Delegation of Authority

Delegation of authority is the internal policy that names who at a company may approve a purchase, sign a contract, or authorize a change order, and up to what dollar limit. It exists on paper in most manufacturers above $100M in revenue, but the version enforced in practice often diverges from the version written down.

That gap matters to margin drift because approval authority is the last checkpoint before a vendor's terms become a liability the company has agreed to pay. Delegation of authority sets who can commit the company to a vendor cost and at what threshold. Where the policy is vague or unenforced, approval collapses to whoever is closest to the invoice queue, not whoever understands the contract behind it.

The fix is not a stricter policy document.

It is tying each approval threshold to a named contract reference, so an approver above the AP clerk's limit is required to look at terms before a payment clears rather than after a diagnostic finds the gap months later.

1. What is delegation of authority?

Delegation of authority is a written policy assigning approval rights for spend, contracts, and change orders to specific roles or dollar thresholds. It states who may sign a new vendor agreement, who may approve an invoice above a set amount, and who may authorize scope changes mid-contract. The policy typically escalates by size: a supervisor clears small invoices, a controller clears mid-size ones, and only an officer signs new contract terms.

In practice, the thresholds are often years old and untied to current contract terms.

2. Why does it matter for margin drift?

Delegation of authority matters for margin drift because the approver is supposed to be the checkpoint that catches a mismatch between contract and invoice before payment clears. When approval authority is delegated without contract visibility, that checkpoint becomes a rubber stamp. The invoice looks routine to the person clearing it, even when the rate, tier, or cap behind it has drifted from what was agreed.

This is a mechanism, not a frequency claim: the approver's authority and the approver's information are two separate things, and a policy can grant the first without the second.

3. How should thresholds be set?

Thresholds should be set against the specific contract instruments they govern, not just a flat dollar amount. A limit tied only to invoice size lets a recurring accessorial charge or a small volume tier violation clear indefinitely below the radar. A limit tied to the underlying contract term routes anything touching a rate card, cap, or rebate clause to someone who can check it against the agreement.

None of these structures self-enforce. Each depends on whether the approver actually has the contract in hand.

  • Dollar threshold: The most common structure, but weak alone since it ignores contract complexity.
  • Contract-linked threshold: Routes approval based on which clause the invoice touches, not just its size.
  • Category threshold: Assigns review by spend category, useful where terms vary widely by vendor type.

4. How does this connect to the audit process?

A margin drift diagnostic reviews delegation of authority as part of mapping how an invoice actually gets approved, alongside matching invoices to rate cards and volume tiers directly. Where approval authority and contract knowledge are separated, the diagnostic flags the gap as a root cause rather than a one-off finding, because the same gap will keep producing new instances of drift after any single invoice is corrected.

Fixing the policy document without fixing who sees the contract at approval time leaves the underlying gap open.

5. Frequently Asked Questions (People Also Ask)

What is delegation of authority in accounts payable?

It is the policy defining who may approve an invoice or contract commitment, usually tiered by dollar amount or spend category, so that no single person can commit the company beyond their assigned limit without escalation.

Who typically holds delegation of authority at a manufacturer?

Authority is usually split across roles: supervisors for routine invoices, controllers for mid-size approvals, and officers or the CFO for new contracts or terms above a set threshold. The exact split is set by internal policy, not by external standard.

Does delegation of authority prevent margin drift on its own?

No. It defines who may approve spend, not whether that person can verify the invoice against the contract. Without contract visibility at the point of approval, delegation of authority controls who signs off, not whether the sign-off is informed.

How is delegation of authority different from a rate card?

A rate card and delegation of authority govern different things: a rate card states what a vendor may charge, while delegation of authority states who is allowed to approve payment against it. A gap in either one can let drift through independently of the other.

Should delegation of authority thresholds be tied to specific contracts?

Tying thresholds to contract instruments such as caps, tiers, or rebate clauses routes review to someone positioned to check terms, rather than routing purely by invoice size, which can miss recurring charges that are individually small.

Where does delegation of authority show up in a margin drift diagnostic?

It appears when a diagnostic traces how a specific finding was approved in the first place, to determine whether the approval process itself, not just the invoice, needs to change to prevent recurrence.
