The Challenge
The Challenge
Before adopting Mindee’s OCR, Lucca faced two significant hurdles:
- Burdensome Data Entry: Employees had to manually fill in expense forms—even though receipts already contained most of the necessary information—resulting in a slow, error-prone process.
- Time-Consuming Verification: Administrators were required to cross-check manually entered data against receipts to prevent fraud and ensure compliance with local regulations during financial controls.
These challenges not only delayed expense reporting but also increased the risk of non-compliance and inefficiencies.
Our Solution
Lucca evaluated various OCR solutions, and Mindee quickly emerged as the clear frontrunner, thanks to its unmatched accuracy-to-speed ratio.
Today, Mindee’s OCR technology is integrated into three of Lucca’s solutions—two powered by the Receipt API and one by the Invoice API.
Watch this demo to see how Lucca’s spend management platform effortlessly scans and processes expense receipts in real time, streamlining the entire expense reporting process:
Implementation process
Automatic data extraction
Mindee’s OCR accurately extracts crucial information from receipts – the amount, currency, multiple VAT rates, expense category, date, and merchant name – eliminating manual data entry.
Streamlined workflow
For its flagship product, Cleemy Expenses, Lucca built a dedicated microservice that connects to Mindee.
This service abstracts the OCR process by converting synchronous requests into asynchronous ones to manage load and ensure smooth operations.
Enhanced User Experience
The automated extraction dramatically simplifies the expense reporting process.
One memorable example: an admin was astonished to learn that the system now automatically distinguishes between breakfast, lunch, and dinner based on receipt details—removing the need for users to specify the meal manually.
Results & Impact
Integration and Impact
While building a custom stack required some initial effort, Mindee’s APIs were implemented swiftly, and the benefits were immediately evident:
- Massive Document Processing: Lucca processes around 10 million documents per year. Even an estimated saving of 10 seconds per document results in significant time savings across the organization.
- Efficiency Gains: By automating data entry and verification, the time required to complete an expense form is effectively halved—allowing staff to focus on more strategic tasks.
- Competitive Advantage: When first integrated, Mindee’s OCR was a clear differentiator in a competitive market. Today, it remains one of Lucca’s top three “wow effects” during product demonstrations.
- Outstanding Support: Lucca praises Mindee’s responsive and expert support, which has been crucial in overcoming integration challenges and continuously improving the solution.
Looking Ahead
Lucca views its collaboration with Mindee as a long-term partnership. To further enhance its platform, Lucca aims to:
- Increase Accuracy: Continuously push towards 100% OCR accuracy, minimizing manual intervention even further.
- Expand Data Extraction Capabilities: Work with Mindee to extract additional fields specific to the HR and finance sectors, and explore new use cases such as processing vehicle documents (e.g., “cartes grises”).
- Maintain a Competitive Edge: Keep refining the OCR integration to stay ahead in an increasingly competitive market, ensuring the best possible user experience.
At Lucca, we work to provide our customers with the best finance solutions integrated into an HR platform, and Mindee has been a key partner in achieving this.
