Air freight is the preferred choice for time-sensitive and high-value shipments, playing a pivotal role in fast-paced global supply chains. However, with speed comes complexity – especially when it comes to managing and verifying freight costs. That’s where air freight audit processing becomes essential, involving the systematic review and validation of air freight invoices to ensure billing accuracy, contractual compliance and overall cost efficiency.
Let’s break down what the process entails – why it matters, how it works, the challenges involved and how businesses can implement it effectively.
Air freight audit processing is the detailed review of air freight charges to validate accuracy and ensure alignment with agreed-upon rates, tariffs, and service terms, ensuring companies are only paying for the services which they contracted and received.
It typically includes verifying freight rates (based on chargeable weight), checking surcharges and accessorial fees, reviewing currency conversions and tax applications, matching documentation (invoice, air waybill and contracts) and identifying and resolving discrepancies.
So why is audit processing so important? Well, to start, companies can recoup 2–8% of total air freight spend by identifying billing errors. This financial control helps to keep transportation budgets accurate and predictable, along with the assurance of compliance to carrier agreements and international trade regulations at every stage of the process.
Invaluable performance insights are available in the form of access to data to evaluate carrier performance and shipping efficiency and detect duplicates or inflated billing.
At this point, it’s useful for us to see the six crucial steps make up a successful audit processing workflow:
Step 1: Data Collection
This involves the gathering of all relevant documents and data points, including freight invoices, Air Waybills (AWBs), rate agreements or contracts, shipment tracking data and customs declarations (if applicable).
Step 2: Invoice Matching
Marrying up invoices with the corresponding shipment record, quoted or contracted rates along with AWB and booking details
Step 3: Charge Verification
The auditing of freight charges, based on chargeable weight (actual vs. dimensional weight) and surcharges including fuel, security, terminal handling, war risk, etc. Accessorial fees include collection, delivery, documentation and customs clearance the accuracy of conversion to billing currency must also be factored in here.
Step 4: Exception Handling
The identification of mismatches or overcharges, flagging them for investigation and then escalating to dispute resolution if appropriate.
Step 5: Dispute Resolution
Involves working with carriers or freight forwarders to resolve discrepancies, which may involve providing supporting documents, requesting credits or refunds and adjusting future invoices accordingly.
Step 6: Reporting and Analytics
Reports are generated to enable the tracking of savings from recovered charges, the monitoring of error types and root causes and the evaluation of carrier compliance and performance to in turn support procurement and rate negotiations.
As with all processes, there are common issues to be found when utilising air freight audit processing. These include factors such as incorrect chargeable weight calculations, unapproved or inflated surcharges, billing for unshipped or duplicate shipments, errors in fuel or security surcharge rates and mismatches between invoice and AWB data.
Complexities can also include variability in invoice formats and fee structures and the volume of transactions – high shipment volumes increase the chance for human error in manual audits.
As with most managed processes, the benefits of technology are a major development in the enhancement of streamlining and overall vastly improved accuracy.
Freight Audit and Payment (FAP) Systems centralise processing and automate validation, whilst Optical Character Recognition (OCR) digitises paper invoices and AWBs
Machine learning identifies patterns in common errors or discrepancies and integrated dashboards aid with the visualisation of costs, trends and KPIs in real time.
APIs and integrations connect to transportation management systems (TMS), ERPs, and carrier systems for seamless data exchange.
Best practice includes the standardisation of documentation, requesting consistent formats from carriers, automatic dimensional weight calculations to identify errors and regularly updated rate agreements to ensure all current contract rates are loaded into the audit platform.
Air freight audit processing is a mission-critical function for companies who rely on air cargo to keep their global supply chains moving. With high stakes and costly mistakes, a structured and tech-enabled audit process ensures billing accuracy, recovers unnecessary spend, and builds a foundation for better vendor management and operational efficiency. In a world of fast-moving goods and tight margins, those who audit well gain not only financial control but also strategic insight into their logistics operations.
