Billing Leakage Audit: Where 3PLs Lose Revenue They Already Earned
Billing leakage is revenue you already earned but never invoiced — accessorials, storage, detention, returns handling, and ad-hoc work that gets captured on a clipboard, a spreadsheet, or in someone’s memory and never makes it onto the invoice. Across the industry it commonly runs 2–9% of annual revenue. Work through the 30-point audit below, then enter your email to reveal your leakage-risk score and a tailored next step.
How to use this audit
For each statement, click Yes or No based on how your operation runs today. Each section shows a running risk score; the more risk indicators you flag, the more revenue is likely slipping through.
Section 1: Accessorial Capture Risk: 0 / 5
Are all accessorial services recorded digitally at the point of work?
Do operators rely on clipboards, spreadsheets, emails, or memory to record billable activities?
Can billing events be tied directly to a user, timestamp, customer, and order?
Can billing generate reports showing performed versus invoiced accessorials?
Have you audited accessorial billing within the last 12 months?
Section 2: Storage Billing Risk: 0 / 5
Are storage charges based on daily inventory positions?
Are inventory snapshots retained historically?
Can storage calculations be reproduced from WMS records?
Does billing rely on spreadsheets outside the WMS?
Have storage invoices been validated in the last year?
Section 3: Detention & Yard Charges Risk: 0 / 5
Is detention tracked when the event begins?
Is detention linked to customer and trailer records?
Are carrier detention invoices reconciled against customer invoices?
Is detention automatically passed through to billing?
Are detention write-offs measured monthly?
Section 4: Returns Processing Risk: 0 / 5
Are return receipt events billable?
Are inspections billable?
Are restocking activities billable?
Are quarantine activities billable?
Are return workflows included in customer contracts?
Section 5: Ad-Hoc Requests Risk: 0 / 5
Can operations create billable events for ad-hoc work even without a PO?
Are customer service requests logged centrally?
Are special projects tracked separately?
Is staged inventory work billable?
Are exception requests audited monthly?
Section 6: Contract Management Risk: 0 / 5
Are annual escalations tracked automatically?
Are contract effective dates monitored?
Are billing rates updated automatically?
Are expired contracts identified proactively?
Are customer-specific rate tables reviewed annually?

Frequently asked questions
What is billing leakage in a 3PL?
Billing leakage is revenue a warehouse has already earned through work it performed — accessorials, storage, detention, returns handling, ad-hoc projects — but never invoiced. It usually happens quietly: work gets captured on a clipboard, a spreadsheet, an email, or in someone’s memory, and never makes it onto the invoice. Across the industry it commonly runs 2–9% of annual revenue.
How does this billing leakage audit work?
Answer 30 yes/no questions across six areas where 3PLs lose billable revenue: accessorial capture, storage billing, detention and yard charges, returns processing, ad-hoc requests, and contract management. The audit scores your exposure from Low to Critical Revenue Recovery Opportunity, and a built-in estimator turns that into an estimated annual dollar opportunity based on your own revenue.
What does my score mean?
Each answer that points to uncaptured or unverified billing adds a risk point. 0–3 is Low Leakage Risk, 4–7 is Moderate, 8–12 is High, and 13 or more is a Critical Revenue Recovery Opportunity. A higher score does not mean your team is doing anything wrong — it usually means billable work is being captured outside the system, where it is easy to lose.
What is the single biggest source of billing leakage?
Accessorial and ad-hoc work that is recorded manually instead of digitally at the point of work. When a billing event cannot be tied directly to a user, timestamp, customer, and order inside the WMS, it is the first thing to slip through during a busy shift. Tightening that one capture point recovers more revenue than any other single change for most operations.
What should I do with my result?
If you land in Moderate or above, the fastest path is a short review of your results with someone who has seen how other 3PLs closed the same gaps. We can walk through where your billable work is being captured today and whether Codeworks Enterprise or Essentials makes sense for tightening it — no obligation, and often the answer is a process change rather than new software.
