## Quick answer

Operational reconciliation is the check of the charter invoice against the measured service: each trip and each kilometer charged by the carrier is compared with what was planned, executed and authorized, according to the contract rules. In Merus Tracker, differences appear trip by trip, with origin and history, so the company can review the charges before paying and have data to renegotiate.

## In short

- Checking the invoice requires three references: the contract, the measured service and what the carrier charges.
- Reconciliation is done trip by trip, not by the month's total.
- Common differences: mileage above planned, extra trips without authorization and trips not completed.
- Merus shows the differences; approval, deductions and payment remain with the company.
- The history of reconciliations becomes a database for renegotiating the contract.

## Why the charter invoice is hard to check

The charter invoice usually arrives as a summary: total trips, total kilometers, extras and final amount. To check it, someone at the company has to rebuild the month with spreadsheets, PDF contracts and the carrier's own report.

The result is predictable: checking becomes sampling, small differences slip through and large ones become arguments without data. The **operational reconciliation** solves this by changing the unit of analysis: instead of the month's total, checking is done trip by trip.

## The three references of reconciliation

| Reference | Question it answers | Source in Merus |
| --- | --- | --- |
| Contract | What was agreed and how is it charged? | Registered rules, amounts, tolerances and vehicles |
| Measured service | What actually happened? | [Independent measurement](https://merustracker.com.br/en/plataforma/auditoria/medicao-independente/) and boardings |
| Billing | What is the carrier charging? | Supplier reports or integration |

When all three are tied to the same trip, every line of the invoice can be explained.

## Step by step: how to reconcile the invoice

### 1. Register the contract rules

Amounts per kilometer or per trip, delay tolerances, rules for extra trips, vehicle types and planned penalties. The Merus team does this loading together with the company's team during implementation.

### 2. Receive the carrier's records

The supplier's reports come in as files or through integration and are matched to the corresponding trips, without requiring the carrier to change the format it already uses.

### 3. Compare trip by trip

For each trip, Merus places side by side:

- planned, measured and charged mileage;
- planned, completed and charged trip;
- contracted vehicle and vehicle used;
- planned and observed times;
- extras and the corresponding authorization.

### 4. Classify the differences

Each discrepancy gets a classification: justified difference (an authorized detour, for example), difference to dispute, or inconclusive case due to missing data.

### 5. Record the decision and close the cycle

Decisions stay in the history, with the responsible party and justification. The company approves the invoice with confidence or sends disputes to the carrier with the evidence for each case.

## The most common differences on a charter invoice

### Mileage above planned

It may be an unauthorized detour, a route change that was never formalized or a calculation error. Comparing the planned route with the measured route shows where the difference arose.

### Extra trips without authorization

Trips outside the schedule charged without a record of who requested them. Reconciliation ties each extra to its authorization, or shows that none exists.

### Trips not completed or incomplete

Trips charged that do not appear in the measurement or that did not pass through all stops. Before disputing, the company checks whether there was an equipment failure.

### Vehicle different from the one contracted

A minibus in place of a bus can change the amount owed under the contract.

### Rules applied inconsistently

Tolerances, rounding and allowances interpreted differently by the parties. With the rules registered, their application becomes transparent.

## Reconciliation is not automatic deduction

This is an important point. Merus **does not approve invoices, apply discounts or execute payments**. The platform organizes the evidence so that the decision, which belongs to the company, is made with complete information. This protects the relationship with the carrier: discussions become about facts, not versions.

## From checking to renegotiation

After a few cycles, reconciliation becomes a valuable historical base:

| Accumulated data | Use in renegotiation |
| --- | --- |
| Real occupancy per line | Adjust vehicle sizes |
| Real mileage per route | Review the contracted amount per route |
| Punctuality by line and time | Negotiate service levels |
| Frequency of extras | Reorganize the trip schedule |

Combined with the [planned versus actual](https://merustracker.com.br/en/plataforma/auditoria/previsto-vs-realizado/), reconciliation shows not only how much is paid, but whether the contracted service still makes sense for the operation.

## Who uses reconciliation in the company

- **Procurement and contracts:** check the billing and lead the renegotiation.
- **Finance:** approves payment with the evidence attached.
- **Facilities and operations:** explain the operational differences.
- **Internal audit:** consults the history of decisions.

If the company does not have a team for this, the Merus team can operate the platform according to the contract, including checking. The transport itself stays with the contracted carrier.

FAQ

## Frequently asked questions

**How do you check the corporate charter invoice?**

Compare, trip by trip, what the carrier charges against what was planned and what was independently measured, applying the contract rules. Merus lines up these three references side by side and highlights the differences.

**Is checking the charter transport invoice the same as a freight audit?**

No. A freight audit deals with cargo transport: bills of lading, weight, rate tables and delivery. Checking the charter transport invoice deals with contracted transport of people: trips, times, kilometres, vehicle and boardings, compared with the plan and with an independent measurement. Merus Tracker serves passenger charter transport and is not a cargo freight management system.

**Does Merus automatically approve or deduct from the invoice?**

No. Merus shows the evidence and the differences. Approving, deducting or paying remains the company's decision, according to the contract.

**What differences does reconciliation usually find?**

Executed mileage different from planned, extra trips without recorded authorization, trips not completed or incomplete, a vehicle different from the one contracted and tolerance rules applied inconsistently.

**Do I need to receive the carrier's data in a specific format?**

No. Merus receives reports as files or through integration and organizes the records by trip. Data loading and mapping are done by the Merus team during implementation.

**Is reconciliation useful for renegotiating the contract?**

Yes. The history of trips, kilometers, occupancy and differences shows how the service really works and gives the company concrete data to review routes, fleet and amounts.

**How often should reconciliation be done?**

In the same cycle as the invoice, usually monthly. Since execution is monitored every day, most differences already arrive at closing with an explanation.
