The next step is to set up your workflow in your expense management software.

Before that, let's quickly revisit how a manual workflow without AI and automation looks like.

1. Expense Incurrence: Employees rack up expenses – travel, meals, you name it. They cling to receipts like precious artifacts, which, let's face it, often end up washed-out after a laundry expedition.

2. Manual Data Entry: Employees manually log expenses. Think spreadsheets, crumpled receipts, and the occasional coffee stain. It's a painstaking process, riddled with human error and about as efficient as a one-legged race.

3. Expense Report Generation: The process of trying to compile these spreadsheets into something resembling an expense report.

4. Cumbersome Approvals: Managers then step into the arena to battle policy compliance and reasonability. This process often involves more back-and-forth than a ping-pong match.

5. Slow Reimbursements: Once approved, employees enter the stage of reimbursement waiting times. It's a limbo where time stands still and morale often takes a hit.

6. Data Entry in ERP/accounting software: Data entry – the bane of the finance team's existence returns again. Manually inputting the data into the accounting systems with correct categorization and coding is as thrilling as watching paint dry.

7. Insights? More Like Hindsight: Periodic reports are generated, offering insights that are often as timely as yesterday's newspaper.

Automation and Artificial Intelligence has transformed this gloomy landscape.

A modern expense management software like Nanonets employs these technological advancements to make expense management seamless, efficient and error-free.

Now let's take a look at how the automated expense management workflow looks like with Nanonets.

2. Auto-Magic Recording: Optical Character Recognition (OCR) technology steps in, extracting structured data from receipts into digital data faster than you can say "expensed."

3. Expense Categorization and GL coding: Nanonets offers the flexibility to customize rules and categories according to your specific needs. You can turn on Intelligent Expense Categorization, customize expense categories and subcategories based on your business needs, and Nanonets automatically assigns expenses to the appropriate categories, subcategories, and detect anomalies for further review. What's more, this feature works out-of-the-box without requiring any training data!

GL code assignment can be effectively executed by -

  • Training on past data: With Nanonets, you can train a machine learning model to recognize and categorize financial transactions. This involves uploading historical financial documents and transactions tagged with historically correct GL codes. The model learns from these examples to accurately predict GL codes for new transactions.
  • Out of the Box Gen AI: By using Nanonets GenAI, our software can interpret the text on financial documents in a way that mimics human understanding. This allows it to extract relevant information, context and semantics in order to apply complex reasoning to assign GL codes accurately, even in cases where transaction details are ambiguous or sparse.

4. Real-Time Reporting: Reports are generated with the click of a button – it's like having your own personal assistant, minus the coffee runs. Real-time data is present in the system ensuring complete visibility into business expenses without lag and errors.

5. Easy Approvals: System-driven compliance checks kick in first, flagging only the outliers. Managers get to focus on real issues instead of playing Whack-a-Mole with every report. You can then add humans-in-the-loop to ensure invoices are sent to approval to the right person at the right time. Furthermore, you can enforce your approval policy and custom validation checks.

6. Compliance Cruise Control: Continuous, automated audits make life easier. Anomalies stick out like a sore thumb, and policy enforcement is tighter than a drum.

7. Speed of Light Reimbursements: Reimbursements happen at warp speed, boosting employee morale to the stratosphere.
