Client Profile: A fast-growing wholesale mortgage lender with US operations

The client is a US-based mortgage lender with decades of experience in lending. They specialize in wholesale and correspondent lending. Mortgage brokers and loan originators trust them nationwide. With over 70 product offerings and exceptional service, they are often known as one of the top lending businesses in the country.

As their customer base grew, an increasing number of documents arrived. The client required a more efficient method for organizing borrower documents before entering them into their Loan Origination System (LOS). These documents are large PDF files with multiple forms uploaded at various stages of the loan cycle.

To minimize operational friction and maintain SLA compliance, the lender sought Flatworld.ai to implement a smart indexing system capable of automatically segregating, classifying, and uploading documents in real-time.

Business Need: Faster Document Indexing Without Compromising Accuracy

The manual document indexing was taking a long time, and thus, making the turnaround time longer too. This was slowing down the loan closure process. The borrower's documents came in a single PDF file with all the information merged together. Then, the internal team had to review each file manually, split it, and classify it. This process was not only time-consuming but also prone to error.

The business needed a solution that could do the following :

  • Segregate and find document types within the large, multi-page PDF files.
  • Classify documents accurately based on mortgage-specific requirements.
  • Integrate these documents with their existing LOS.
  • Deliver results within the strict 2-hour window as mentioned in the SLA.
  • Scale across thousands of similar documents without manual intervention.

Inputs Provided by the Client

  • Borrower documents merged into a single PDF file.
  • A list of various documents required for classification.
  • Sample data across different borrower profiles and scenarios.
  • Testing and integration of the LOS.
  • Fine-tuning MSuite models with a feedback loop during UAT.

Deliverables Requested

  • End-to-end automated indexing using MSuite’s Classification module.
  • Smooth integration with the LOS for document routing and uploads.
  • Real-time monitoring and handling exceptions.
  • Custom logic for splitting bundled documents.
  • Performance metrics on indexing speed and accuracy.

How Flatworld.ai Delivered the Solution in Five Phases

01

Scoping and Planning

The first step was to work closely with the lending company's business and operations team and understand the challenges within the present document management flow. Flatworld.ai identified the loan lifecycle stages and the main documents required. Automating high-frequency file tasks saves time and money. Additionally, it was crucial to define clear project milestones at this stage and establish feedback loops. They also planned for phased UAT and ongoing support after deployment.

02

Document Training and Model Calibration

Once the planning phase was complete, Flatworld’s team collected real-world loan files with diverse situations, which were used to train the MSuite’s classification engine. MSuite is our AI-powered document classification and indexing engine.

Training the classification engine enabled the creation of a robust, accurately labeled dataset for model development. It also helped tune classification limitations to minimize false positives. Edge cases, such as handwritten forms and low-resolution scans, were simulated. Finally, the Flatworld.ai team tested the model in a controlled sandbox to ensure the output quality.

03

Execution and LOS Integration

MSuite configuration was aligned with LOS data fields. A LOS is a mortgage workflow platform designed for processing and compliance. Collaboration with the client's LOS necessitated careful consideration of both system compatibility and data integrity.

  • Facilitated the indexing of active loans within the loan origination system.
  • Managed locked-loan disputes through intelligent retry mechanisms.
  • Created a queuing framework for large-scale parallel processing.
  • Confirmed the successful delivery of documents into the designated folders within LOS.
04

Testing and QA

The team performed extensive UAT alongside the client, tracking accuracy and turnaround across different file scenarios.

  • Refined classification logic based on real-time feedback.
  • Reviewed exceptions and added support for rare document types.
  • Ensured all files met the 2-hour SLA under stress tests.
  • Created QA test cases for regression testing in future retraining cycles.
05

Go-live and Continuous Optimization

MSuite was launched in production with complete monitoring and fallback safeguards. The client’s live loan packages were processed in real-time, with metrics reported daily.

  • Enabled custom-built, live dashboards to get visibility into document indexing status and exceptions.
  • Flagged outliers for manual review.
  • Planned quarterly retraining cycles for continued performance improvements.
  • Provided documentation and support for independent model tuning.

Challenges Faced During Implementation

Despite the successful rollout, the team faced several critical hurdles -

  • Simultaneous Loan Locks in LOS: Conflicts occurred when multiple users or systems attempted to access the same loan file. MSuite had to be designed to intelligently retry locked transactions without dropping documents.
  • Scaling Queue Management: Processing a high volume of loan packages without latency required intelligent queue balancing and processing order logic.
  • Strict SLA Compliance: The strict 2-hour deadline had to be maintained, ensuring the result was error-free and requiring real-time processing, fallback mechanisms, and clear exception handling workflows.
  • Document Variation:File quality ranged from high-resolution scans to blurred mobile uploads. MSuite had to deal with these input types with minimal error.

Client Impact: Speed and Accuracy Nailed with Mortgage Document Indexing

Manual indexing is a lengthy process and can’t always be dependable. The client was looking for a solution to end this, and Flatworld.ai delivered. Now they have a reliable system that works smoothly 24/7.

Flatworld’s MSuite delivered a measurable business impact within just weeks of launch

MSuite is helping them meet SLA deadlines, and the indexing process is consistent, monitored, and has a higher accuracy level. These factors are assisting the mortgage lending company in staying ahead of its competitors in a market where turnaround time and compliance are crucial.
