Carrier invoice review and approval

Freight audit software for charges you can explain

Freight audit software compares carrier invoice charges with agreed rates and shipment evidence, routes differences for review, and prepares approved records for accounts. Codeblix offers custom software development and consultation for shippers and logistics teams that need these checks fitted to their own contracts, approval rules and receiving systems. Define the evidence behind each charge before deciding which invoices can move forward.

Outcome first

Give logistics and finance the same charge history.

Importers, distributors and multi-carrier shippers need a review process that can explain the bill, the dispute and the amount finally approved.

01

Match the bill to the service purchased

Specify the carrier, shipment reference, lane, service date and charge codes used to join an invoice to its shipment. Separate an unmatched bill from a rate difference so the right owner receives each exception.

02

Apply the rate that governed the shipment

Keep contract editions, effective dates, currencies and surcharge bases attached to each calculation. A revised rate table should support new decisions while preserving the explanation for earlier approvals.

03

Track the amount through the final handoff

Keep disputed lines, credits, approved amounts and accounts responses connected. Distinguish a review decision from an accepted accounts entry and from a later payment confirmation.

Inside the freight office

From shipment paperwork to an approved accounts handoff.

Connect the shipment context, charge review and finance handoff in one clearly assigned workflow.

01

Choose software, a managed service or custom development

A packaged audit module suits teams whose shipment data, contract formats and exception policies fit its controls. A managed audit service adds operational review responsibilities that should be stated in the agreement. Discuss custom development when your rate editions, multi-entity approvals or accounts handoff require a tailored process. Evaluate each route with the same difficult invoices, implementation effort and support expectations.

02

Ask for the disputed invoice in the demo

Bring a bill that arrived twice, a fuel surcharge based on the wrong contract edition, an unsupported accessorial and a credit received after approval. Ask the provider to show the original records, reviewer authority and remaining balance at every step. A total marked approved is useful only when the line decisions and receiving-system status are explainable.

03

Connect waiting-time evidence to the charge review

If an invoice includes detention or waiting time, the arrival, appointment and service-completion records can support its review. Agree which timestamps govern the contract and who resolves conflicting sources. Keep the operational appointment with its existing owner while the resulting invoice line follows the audit decision.

04

Use calculators for estimates and contracts for approval

A freight cost worksheet helps document assumptions during planning. For invoice approval, use the signed commercial terms, applicable rate edition and actual shipment inputs. Save the estimate separately so an early planning assumption cannot silently become the payable amount.

Workflow evidence

Six stages from carrier invoice to reconciled approval

Use this sequence to assess a packaged product or agree a custom development scope. Each stage needs a record, an owner and a recoverable exception path.

01

Register the invoice and check its identity

Capture the carrier entity, invoice number, currency, document date, charge lines and source file reference. Normalize invoice identifiers under a stated rule. Hold possible duplicates across upload and interface channels for review, including a repeated invoice with different punctuation.

02

Match charges to shipment evidence

Link each charge to its shipment or allocation group using agreed references. Record service dates, mode, route, quantities and supporting delivery or waiting-time documents. Consolidated bills need a documented allocation method; missing references remain visible in an unmatched queue.

03

Calculate the expected charge

Select the contract edition applicable to the agreed service date and lane. Apply the specified unit, minimum charge, surcharge basis and rounding rule. Retain the input snapshot and rule version with the result. Send missing rates, incompatible units and uncertain currency treatment to a reviewer.

04

Separate explainable differences from unresolved charges

Compare invoice lines with expected amounts. Configure line-level and invoice-level tolerance policies separately. Require evidence for additional services such as waiting time or a liftgate. Assign a reason code, owner and next action to every held difference rather than approving it because the invoice total is close.

05

Resolve disputes and authorize the right amount

The logistics reviewer requests evidence or a corrected invoice; the authorized finance approver decides which amount can proceed. Retain correspondence, decisions, credits and invoice versions. Agree whether partial approvals are allowed and how an open disputed balance stays connected to the original bill.

06

Deliver approved records and reconcile responses

Send the approved invoice version, amount, allocation and reference to the receiving accounts workflow. Record its acceptance or rejection. Use a stable delivery key for retries and resolve rejected codes before closing the batch. Link any later payment status from the responsible finance system using its own reference.

Planning area 01

Set authority at the record and charge level

  • Invoice intake clerk: register source documents and repair permitted reference fields; retain the imported values and reason for each correction.
  • Logistics analyst: match shipments, explain variances and request carrier evidence; assign unresolved lines to a named owner.
  • Contract owner: publish effective-dated rate editions and define surcharge or tolerance policies; preserve historical calculation inputs.
  • Finance approver: authorize amounts within the agreed delegation and review partial approvals, credits and policy overrides.
  • Accounts operator: reconcile accepted or rejected deliveries with the receiving system; attach settlement references supplied by finance.
  • Carrier collaboration: scope access to that carrier’s invoices and evidence requests, with separate authority for submitting documents and approving charges.
Planning area 02

Scope migration, interfaces and ongoing support

  • Discovery inputs: anonymized invoices, rate contracts, shipment extracts, charge-code mappings and examples of disputes, credits and approvals.
  • Migration: map carrier entities, invoice identities, currencies and open balances. Reconcile a sample of approved, disputed and credited invoices before importing history.
  • Interfaces: agree the actual TMS, carrier file or EDI format, and receiving accounts API or CSV contract. Quote each data direction, schedule, acknowledgement and retry responsibility.
  • Multiple currencies: define the currency of each rate and bill, conversion source and effective date where conversion is needed. Finance should approve the treatment used by the workflow.
  • Deployment: specify hosting, document access, retention, backups, restore checks, training and the cutover reconciliation for invoices arriving during transition.
  • Commercial scope: request separate estimates for rule configuration, custom interfaces, migration and support. Set maintenance ownership, response hours and how new carrier formats or contract editions enter change control.
  • Payment responsibilities: identify the approved finance system and authorized people responsible for releasing funds. Agree separately any payment-provider work and confirmation exchange.
Your operating specification

Specify six connected records before choosing a platform

The useful unit of review is a charge with its shipment, rate and decision history. This model makes the evidence and handoff explicit enough to compare vendor demonstrations and request a development quote.

Illustrative record set: SHP-204 · RATE-07 · INV-882. Sample amounts are in USD and exclude taxes.
RecordExample inputsRequired output and control
Shipment evidenceSHP-204 · carrier · lane · service date · quantity/unit · delivery or waiting-time documentsIdentify the source for each fact and retain changes. Unmatched invoice lines remain held until their shipment or allocation is resolved.
Rate agreement editionRATE-07 · carrier entity · effective dates · lane/service · currency · base charge · fuel basis · accessorial rulesSelect by the agreed contract date rule. Save the edition and inputs used in each audit calculation.
Carrier invoice and charge linesINV-882 · carrier · invoice identity · currency · version · charge code · quantity · billed amountPreserve source document and original values. A duplicate candidate enters review; a corrected invoice stays linked to its predecessor.
Audit resultAUD-204 · invoice line · expected amount · variance · rate edition · tolerance policy · evidence referenceStore the calculation explanation. Missing evidence, ambiguous units and unsupported accessorials create distinct exceptions.
Exception and approvalEXC-18 · reason · owner · requested evidence · carrier response · authorized amount · approver · decision timeKeep unresolved balances open. Changing an approved amount requires a traceable decision and an updated downstream handoff.
Accounts delivery and credit reconciliationDEL-882 · approved invoice/version · amount · delivery key · accepted/rejected · credit reference · finance statusReplaying the same delivery does not create a second entry. Record the receiving acknowledgement and reconcile credits to the affected amount.

Worked example: RATE-07 specifies a USD 900 base charge and fuel at 15% of that base: USD 135. The expected total is USD 1,035. INV-882 bills USD 900 base, USD 180 fuel and USD 75 waiting time, totaling USD 1,155. Review the USD 45 fuel difference and hold the USD 75 waiting-time line for contract and timestamp evidence. The USD 120 difference is a review item, not a realized saving. If the authorized outcome is USD 1,035 with a USD 120 credit, preserve that decision and reconcile the credit or corrected invoice before closing the remaining balance. Partial approval depends on your agreed finance policy.

Frequently asked questions

Questions before starting a freight audit software project

Resolve the rules, data and authority with logistics and finance before agreeing the implementation.

What does Codeblix offer for freight audit software?

Codeblix provides custom software development and consultation to scope carrier invoice matching, rate checks, exception review and accounts handoffs. Bring sample bills, contract editions and approval rules so the development scope and quote address your actual process.

How is freight audit different from general invoice approval?

General approval establishes who can authorize an invoice. Freight audit also needs shipment matching and charge calculations against the relevant transport agreement, including service dates, units, fuel and accessorial evidence. Both workflows need a clear handoff, but their review inputs differ.

Should we buy a package, use a service or commission a custom build?

Compare packaged controls against your carrier formats and contracts first. A managed service may suit teams that want ongoing operational review. Discuss a custom build when the record structure, exception ownership or integration requirements need a tailored design. Use the same sample invoices to evaluate all routes.

Can the workflow handle duplicate invoices and corrected bills?

Include identity normalization, carrier entity and cross-channel duplicate checks in the scope. Define how an analyst resolves a duplicate candidate and how corrected versions link to the earlier bill. Test those rules with your real naming conventions and input formats.

How should fuel, waiting time and other extra charges be reviewed?

Record the contract edition, calculation basis and supporting shipment evidence for each line. Fuel may use a specified base or index; waiting time may use defined timestamps and allowances. Agree the applicable terms with your contract owner and retain unresolved lines for a named reviewer.

Can Codeblix connect the audit workflow to our TMS or accounts system?

Interface feasibility is reviewed from the actual API, file or EDI specification, access method and sample records. The development scope should state which data moves, in which direction, how often and how acceptance or rejection is reconciled. Supply those details with the quote request.

Does approving an invoice also release payment?

Approval determines the amount authorized for the next finance step. Funds are released by the people and systems assigned in your payment policy. Define any payment service separately and connect its confirmations to the invoice record when that exchange is part of the agreed scope.

What affects the development price and support plan?

The estimate depends on carrier formats, rate-rule complexity, invoice volume, entities, interfaces, migration and review permissions. Provide difficult cases as well as normal bills, your hosting constraints and expected support hours. Agree staged acceptance, maintenance ownership and how new contracts or interfaces are priced.
