Protect Your Margin Across Your Carrier Spend

For a forwarder, margin lives in the gap between what you buy from carriers in volume and what you sell across your customers. Overcharges that go unaudited erode that gap quietly, across thousands of shipments. Portcast's freight audit is designed for how forwarders actually buy and sell, so carrier billing errors get caught before they cost you at scale.

Ocean Freight Invoices Are Full of Errors, and Manual Audits Miss Them

Freight invoices are hard to verify, and most teams still run this audit manually in spreadsheets. Invoices arrive in inconsistent formats with vague charge descriptions, and have to be checked line by line against contracts, shipment timelines, and agreed terms. That is slow, and it lets overcharges slip through.

Overbilling & Surcharges

Accessorial fees and surcharges are billed outside agreed contract terms.

Miscalculation

Detention and demurrage charges are miscalculated against your actual free time

Manual Errors

Time-consuming manual checks resulting in missed discrepancies

Every Carrier Overcharge You Miss Comes Out of Your Margin

Across thousands of shipments, unaudited carrier overcharges add up to real leakage. Most teams still check carrier invoices manually in spreadsheets, which does not scale across a full book of business

Complexity

Invoices arrive from a mix of carriers in different formats, each needing to be checked against the volume rates you negotiated

Overbilling

Accessorial fees get billed outside agreed conditions

Miscalculation

Detention and demurrage charges are miscalculated against your free time terms

Surcharges

Surcharges appear that were never in the contract, sometimes surfacing only when a customer questions their bill

Review and Resolve
Track disputes through a tailored workflow, assign ownership, and export clear dispute summaries to speed up carrier follow-ups and cost recovery.

How Freight Audit Fits a Forwarder's Buy and Sell

Forwarder audit is not the same as shipper audit. You do not buy one carrier per lane; you buy volume and resell it across customers, and your contracts and D&D terms are structured around that. Portcast fits the audit to how your buy and sell actually work.

Bring In Your Carrier Invoices and Terms
Carrier invoices, buy rates, and volume terms flow in through integration with your existing systems, so there's no need for manual re-keying.
Check Charges Against Your Volume Buy Terms
Every carrier charge is checked against your agreed rates, free time terms, and actual shipment milestones. This helps identify overcharges, incorrect accessorials, and D&D charges that do not match what happened.
Reporting and Evidence at Book Scale
See which carriers, lanes, and charge types are driving the most leakage. Use shipment evidence to raise the issue directly with the carrier.
Bill Customers on What Actually Happened
The shipment evidence behind each charge gives you the proof to dispute incorrect D&D and accessorial charges with customers or carriers. Use the milestone data to support claims and resolve disputes faster.

What Portcast's
Freight Audit Software Delivers

Cut Audit Time by 10X

Automated extraction and validation reduce manual effort and move audits from days to minutes, so your team reviews exceptions instead of every line item.

Unlock Up to 30% Savings

Catch overcharges and enforce contract terms before invoices are paid. Our customers have seen up to 30% cost savings by resolving billing errors quickly and accurately.

Achieve 99%+ Extraction Accuracy

AI trained on thousands of shipping documents from major carriers extracts structured data with over 99% accuracy, the foundation that makes touchless auditing possible.

Enable 95%+ Touchless Processing

High-accuracy document extraction audits most invoices end-to-end without manual intervention.

Why Freight Audit Matters for Forwarders

Protect Margin at Scale

When margin is a spread across high volume, small per-invoice errors compound into significant leakage. Systematically catching carrier overcharges protects the margin you have already earned.

Audit Without Adding Headcount

Manual invoice checks do not scale with your book. Automated extraction and validation let your team focus on the exceptions that matter, not line-by-line data entry across every carrier.

99%+ Extraction Accuracy

AI trained on thousands of shipping documents from major carriers reads invoices from across your carrier mix with over 99% accuracy, the foundation for auditing at volume.

95%+ Touchless Processing

High-accuracy extraction handles the vast majority of carrier invoices end-to-end, so scale does not mean more manual work.

Freight Audit Software: Frequently Asked Questions

Any other question that isn’t mentioned? Don't hesitate to get in touch.

What is a freight audit, and why is it important?

A freight audit is the process of verifying shipping invoices against contracted rates and actual shipment data. It catches billing errors, enforces contract terms, and recovers overpayments before they become sunk costs. For ocean freight teams handling large invoice volumes, with complex rules around free time, D&D, and carrier surcharges, automating the audit is the only way to scale without adding headcount.

How does Portcast's AI-powered freight audit work?

Portcast uses AI trained on thousands of shipping documents from major ocean carriers to extract structured data from freight invoices with 99%+ accuracy. It then validates every charge against your contract terms, free time allowances, and actual shipment milestones, flagging discrepancies automatically and generating dispute-ready summaries. More than 95% of invoices are processed touchlessly, with exceptions routed to your team.

What types of billing errors does a freight audit help identify?

Portcast detects charges that exceed contracted rates, detention and demurrage miscalculated against actual free time, accessorial fees billed outside agreed conditions, duplicate charges, and fees that should not have applied under your contract. Each flagged charge is surfaced with the exact amount and the relevant contract reference, so your team knows exactly what to dispute.

What are the benefits of AI freight audit instead of manual auditing?

AI freight audit cuts audit cycle time by up to 10X, reduces human error, and handles invoice volumes that manual freight bill audit processes cannot scale to. It also catches complex D&D and accessorial errors that slip through manual review at volume and automatically generates dispute-ready summaries, so your team recovers costs faster.

How does a freight audit system compare to using freight audit service providers?

A freight audit system automates the checks in-house, giving your team direct control and real-time results, whereas traditional freight audit service providers and freight audit companies typically run the process for you on a recovery-fee basis. Portcast gives you the system: your team retains ownership of the data, disputes, and recovered costs, without handing the process to a third party.

How is Portcast different from traditional freight audit and payment providers?

Portcast focuses on freight audit intelligence rather than freight audit and payment processing. Instead of moving your money, it gives your team accurate, dispute-ready audit results and a workflow to recover overcharges. For ocean freight teams, the value is in the depth of the audit: catching the D&D and accessorial errors that generic freight audit and payment software, built primarily for road and parcel, tends to miss.

Is Portcast suitable for ocean freight only?

Portcast's freight audit is purpose-built for ocean freight, trained on ocean carrier documents and ocean-specific billing rules like free time and D&D. That focus is deliberate. It is what lets the audit go deeper than multimodal tools that treat ocean as one mode among many.

Freight Audit for Forwarders: Frequently Asked Questions

Any other question that isn’t mentioned? Don't hesitate to get in touch.

How is freight audit different for a forwarder than for a shipper?

A shipper typically audits one carrier contract per lane. A forwarder buys freight in volume and resells it across customers, so the contracts, rates, and even D&D terms are structured differently. That is why a forwarder audit needs to validate carrier charges against volume-buy terms rather than a single per-lane rate, and why Portcast is building for that specifically rather than applying shipper logic as-is.

What can Portcast audit for forwarders today?

Portcast's freight audit and its underlying AI were built for ocean shippers first. The document extraction, shipment-milestone validation, and freight-trained AI apply broadly, but forwarder-specific audit, built around volume buys and resale, is something we are actively developing. The best next step is a conversation about your workflow so we build it around real forwarder structures.

How does Portcast's AI read invoices from many carriers?

Portcast's AI is trained on thousands of shipping documents from major ocean carriers and handles multilingual and non-standard invoice formats, so a mixed carrier base does not require a template for each carrier. Every invoice is normalized into structured data with 99%+ extraction accuracy.

What types of billing errors does freight audit catch?

Charges that exceed agreed rates, detention and demurrage miscalculated against free time, accessorial fees billed outside agreed conditions, duplicate charges, and fees that should not have applied. Each is surfaced against the shipment evidence, so you know what to take to the carrier.

How is Portcast different from traditional freight audit and payment providers?

Portcast focuses on freight audit intelligence rather than freight audit and payment processing. Instead of moving your money, it gives you accurate, evidence-backed audit results. For ocean freight, the value is in the depth of the audit, catching the D&D and accessorial errors that generic tools built primarily for road and parcel tend to miss.

Is Portcast suitable for ocean freight only?

Portcast's freight audit is purpose-built for ocean freight, trained on ocean carrier documents and ocean-specific billing rules like free time and D&D. That focus is what lets the audit go deeper than multimodal tools that treat ocean as one mode among many.
