Data Entry

Manual data entry

Data entry is the process of extracting and entering relevant information in a computerized system or ERP software. This is an essential process in businesses that seek to reorganize data into convenient formats for additional downstream processing.

For example, Accounts Payable teams in organizations have to extract data from important fields in supplier invoices. This data extraction process  is then followed by data entry into ERP software for accounting or financial reporting purposes.

Data entry is typically a manual, repetitive & menial process that takes up a lot of time. Therefore, companies often outsource their data entry requirements. This allows employees to focus on more productive tasks that directly impact the bottom line.

Whether handled in-house or outsourced, data entry tends to be a time consuming manual process prone to errors & rework. Data is often shared among organizations in non-standard formats; and they are often filled with redundant/irrelevant info or data defects. When operating at scale, these factors could cause serious delays and cost overruns.

A Gartner study estimates that human data entry errors in finance processes alone add roughly “25000 hours of avoidable rework at a cost of $878,000 per year”. The study goes on to show how data entry automation among other solutions can help save time & resources in a huge way!

Data Entry Automation

automating data entry

Data entry automation refers to software-based solutions that can optimize data entry by eliminating or reducing manual processes. Such software can typically extract data from PDFs, documents, images, emails or websites and present just the relevant info in a structured format (csv, JSON, XML etc.).

Automated data entry software leverage RPA & OCR (like zonal OCR) among other technologies to handle repetitive tasks & “read” documents at scale. They are accurate, flexible, scalable & fast, saving businesses precious time & resources.

Automated data entry solutions allow employees to focus on high-value tasks that impact overall productivity while automating time-consuming repetitive/menial tasks! For example, here’s an efficient automated solution to rename PDF files based on their content.

The Automated Data Entry Process

An end-to-end automated data entry process involves the following steps:

Uploading or adding a data source

Organizations receive raw unstructured data in the form of documents, images or scanned files. These are to be imported into the data entry automation software/system.

Pre-processing each file or document

This vital step turns the documents into machine readable formats. Advanced OCR, AI & ML capabilities allow algorithms to “read & understand” documents.

Recognizing & extracting the data of interest

The data entry automation software recognizes & extracts only relevant portions of data. The algorithm can be trained to identify fields & data points of interest.

Validating the extracted data

This optional step allows for a manual or semi-automated verification based on validation rules. Extracted data can be checked for accuracy and can even be improved upon, if needed.

Sharing & entering the extracted data

The final step in the data entry automation process is to send the extracted data to an appropriate destination. The extracted data, presented as a structured output (csv, XML, JSON, Excel etc.), can be conveniently imported into ERP software for additional downstream workflows.

The automated data entry process

Almost all organizational processes & workflows can benefit from data entry automation. Here are some popular use cases:

  • Pulling out information from invoices, POs, bank statements or receipts for financial/accounting purposes.
  • Storing key customer info for efficient customer service.
  • Capturing data from resumes for HR workflows.
  • Generating reports from generic business data.
  • ID verification & KYC processes.
  • Scraping documents or websites for data collection.

Benefits of Automating Data Entry

Automated data entry software (like Nanonets) eliminate the inefficiencies & drudgery of manual data entry. Businesses are increasingly automating data entry to focus exclusively on data review and make relevant business decisions.

Here are some benefits of adopting data entry automation:

Greater accuracy

Automated data entry software like Nanonets leverage AI & ML capabilities to extract data accurately and minimise post-processing. Such algorithms are equipped to handle common data constraints & eliminate errors.

Reduce overall costs

Reduce operational costs & overheads by eliminating inefficient manual processes. Avoid outsourcing or employing dedicated data entry professionals.

Save time

Faster data entry allows for improved data/document processing workflows. Save more than 75% of time spent on manual data entry.

Highly scalable

Handle large volumes of data and sudden spikes in data entry demand.

Increase productivity

Allocate resources & man-hours to productive tasks that directly impact the bottom line.

Increase employee satisfaction

Reducing or eliminating the monotony of repetitive manual data entry affects employee engagement positively.

Process documents intelligently

AI-based software like Nanonets, can classify specific document types intelligently. Such software can intelligently classify documents by type (invoice, receipt, bill etc.) or source (supplier, vendor, internal etc.) for further processing & data entry.

Data Entry Automation with Nanonets

Nanonets intro

Nanonets is an automated data entry software with advanced AI/ML capabilities. Nanonets' intelligent document processing use cases help organisations adopt automation seamlessly. Here are two case studies:

Automating data entry is pretty straightforward with Nanonets. Choose from any of the three options below depending on your use case:

Pre-trained Data Entry Model

If you are looking to automate data entry for processes that involve invoices, receipts, passports or driver's licenses, then check out Nanonets’ pre-trained models. Each of these models has been trained on millions of documents and performs very well on its respective document types.

  • Login to Nanonets - Select an appropriate pre-trained model - if none suit your use case, skip to the next method (Custom Model)
  • Add the source files - upload the documents from which data needs to be extracted
  • Test & verify - run the Nanonets model & verify the extracted data
  • Export - download the extracted data in a structured format (csv, JSON, XML etc.)
Here’s a demo of Nanonets’ pre-trained Receipt OCR model. Notice that the “Export” option provides XML as the first choice; apart from Excel & csv.


Custom Data Entry Model

If you are looking for custom data entry requirements then build a custom data entry model with Nanonets. You can typically build, train and deploy a model for any document type, in any language, all in under 25 minutes.

  • Login to Nanonets - Create a custom OCR model
  • Add training files - Upload sample documents that will serve as a training set for Nanonets to understand your data entry requirements
  • Annotate text/data on the files - “Teach” Nanonets' AI to identify important data (specific to your requirements) in these training files
  • Train the custom data entry model - Nanonets leverages deep learning to build various OCR models and tests them against each other to pick the most accurate one.
  • Test & verify - Add a couple of files to verify whether the custom model suits your requirements/use case
  • Export - If the data has been recognized, extracted and presented appropriately then export the file to a convenient structured format
Here’s a demo on how to train a custom data extraction model with Nanonets. As shown in the demo above, the “Export” option will provide XML as the first choice.

Nanonets API

Here’s a detailed guide to train or build your own automated data entry software using the Nanonets API. In the documentation, you will find ready to fire code samples in Python, Shell, Ruby, Golang, Java, and C#, as well as detailed API specs for different endpoints.
