Stop Chasing Expense Reports: Automate Mileage Approval

The administrative maze of expense settlements

In most companies with mobile teams —such as maintenance technicians, medical representatives or sales networks—, month-end brings a cumbersome process: settlement of expense reports, entertainment receipts and mileage sheets.

The traditional flow is usually inefficient and error-prone. Employees accumulate paper receipts, fill in manual spreadsheets and print them for the department manager to apply a handwritten signature. Subsequently, the document physically travels to the administration and accounting area for final review and payment.

This analogue model generates three clear operational problems:

1. Loss of productive time: Both employees and managers consume valuable hours chasing signatures and validating data instead of focusing on the business.
2. Lack of control and visibility: The finance department has no real-time forecast of accrued expenses until the paper physically reaches headquarters.
3. Lack of compliance in audits: A printed Excel document with an easily forged handwritten signature weakens internal traceability before tax or management control audits.

The solution is to digitise the internal expense approval flow through electronic signature connected directly to the settlement tool or company ERP.

Internal efficiency: One-click approvals and total mobility

Expense report automation allows transforming a process of days into one resolved in seconds, adapting technology to eliminate any operational barrier:

1. Digital report generation from mobile

Following the BYOD (Bring Your Own Device) strategy, the employee takes photos of their receipts or records their mileage routes from an internal app or web form. At month-end, the system unifies the items and automatically generates a consolidated expense report in immutable PDF format.

2. Simple electronic signature for manager and employee validation

For company control and internal approval processes, simple electronic signature is the optimal modality. Managers do not need to memorise complex passwords or install digital certificates to approve a per diem or mileage. The supervisor receives a notification, reviews the breakdown from their mobile and approves the report with a single click or quick on-screen stroke. The process is immediate and keeps the workflow active.

3. API integration and Webhooks for immediate payment

With the signature engine connected to the ERP via REST API, document status is updated in real time. At the exact instant the manager signs the approval, a webhook notifies the accounting department and automatically activates the transfer order in the payment system, closing the cycle without manual intervention.

Absolute traceability for internal audits

Although maximum simplicity is sought in daily operations with simple signature use, the company gains a level of security and regulatory compliance far superior to traditional paper.

Each completed approval flow autonomously generates an Evidence Document or Audit Trail. This unalterable certificate cryptographically seals the expense report together with its technical metadata: creation, reading and signature timestamps, as well as IP addresses from which the expense was authorised. This traceability guarantees that the company has a transparent, objective and protected history before any labour, tax or internal cost control audit.

Frequently asked questions (FAQs)

Is simple electronic signature legally valid for approving internal expenses?
Yes, it is completely valid. The European eIDAS Regulation supports the use of simple electronic signature for validation of corporate internal documents and processes, granting it full legal effectiveness and evidential validity.

What happens if the expense report includes an incorrect receipt?
The automated flow via API allows the manager to reject document signature by entering an explanatory comment. The system automatically returns the report to the employee’s draft status so they can correct the data, preventing incorrect documentation from reaching the accounting department.

Do managers need to use a company device to sign?
No. Thanks to web compatibility of digital signature mobility tools, managers can review and authorise expense sheets from any smartphone, tablet or computer, facilitating management of distributed or remote working teams.

Conclusion

Managing expense reports and mileage should not be an administrative burden that weighs on field team productivity or collapses finance departments at the end of each month.

Implementing agile simple electronic signature flows integrated directly into the company’s digital ecosystem allows eradicating paper and unifying cost control with the operational speed demanded by the market. The organisation eliminates manual review tasks, accelerates settlements and ensures an internal evidence archive that is transparent, robust and completely professional.
