Businesses rely on accurate and organised data to make informed decisions, manage customers, process orders, maintain product catalogues, and operate efficiently. However, managing business data involves more than simply entering information into a database.
Two important processes that are often confused are data entry and data cleansing.
Although both involve working with business information, they serve different purposes. Data entry focuses on adding information to a system, while data cleansing focuses on identifying and correcting inaccurate, incomplete, duplicated, or inconsistent information.
Understanding the difference between data cleansing and data entry can help businesses choose the right data management solution for their requirements.
What Is Data Entry?
Data entry is the process of entering information from one source into another system, database, spreadsheet, website, application, or software platform.
For example, a business may need to transfer information from paper documents into a digital database.
Common data entry tasks include:
- Entering customer information
- Updating spreadsheets
- Entering invoice information
- Transcribing documents
- Entering product information
- Updating CRM records
- Entering survey responses
- Uploading product catalogues
- Updating inventory information
- Entering financial records
The primary objective of data entry is to ensure information is accurately captured and stored in the required format.

What Is Data Cleansing?
Data cleansing, also known as data cleaning, is the process of identifying and correcting or removing inaccurate, incomplete, duplicated, outdated, or inconsistent information from a dataset.
For example, a customer database may contain:
- Duplicate customer records
- Incorrect phone numbers
- Missing email addresses
- Different address formats
- Incorrect spelling
- Outdated contact information
- Inconsistent company names
Data cleansing helps transform an unreliable dataset into cleaner and more useful business information.
Data Entry vs. Data Cleansing
The simplest way to understand the difference is:
Data entry adds or transfers information.
Data cleansing improves the quality of existing information.
| Feature | Data Entry | Data Cleansing |
|---|---|---|
| Main Purpose | Enter information | Improve existing data |
| Primary Activity | Data capture | Data correction |
| Removes Duplicates | Usually No | Yes |
| Corrects Errors | Limited | Yes |
| Standardises Data | Sometimes | Yes |
| Identifies Missing Information | Sometimes | Yes |
| Suitable for New Records | Yes | Not necessarily |
| Suitable for Existing Databases | Yes | Yes |
| Main Goal | Accurate data entry | Accurate and consistent database |
Although they are different processes, businesses often need both.
Why Data Accuracy Matters
Poor-quality data can affect almost every part of a business.
For example, inaccurate customer information can result in:
- Failed communications
- Incorrect invoices
- Delivery problems
- Duplicate marketing messages
- Poor customer experiences
In eCommerce, inaccurate product information can result in:
- Incorrect product descriptions
- Wrong prices
- Incorrect specifications
- Product returns
- Customer complaints
Accurate data helps businesses operate more efficiently and make better decisions.
Common Data Quality Problems
Before cleansing data, businesses need to understand the types of problems that may exist.
1. Duplicate Records
The same customer or product may appear multiple times in a database.
For example:
ABC Ltd
ABC Limited
ABC Ltd.
These could represent the same organisation.
Identifying and consolidating duplicate records can improve database accuracy.
2. Incorrect Information
Data may contain spelling mistakes, incorrect addresses, invalid phone numbers, or other errors.
These errors can occur during manual data entry, data migration, or information collection.
3. Missing Information
Some records may contain incomplete information.
For example:
- Missing email addresses
- Missing phone numbers
- Missing product specifications
- Missing postcodes
- Missing customer names
Depending on the purpose of the database, missing information may need to be identified and corrected.
4. Inconsistent Formatting
Different employees may enter the same type of information in different formats.
For example:
10/09/2026
09-10-2026
September 10, 2026
A data cleansing process can standardise information into a consistent format.
5. Outdated Data
Business information changes over time.
Customers may change:
- Addresses
- Phone numbers
- Email addresses
- Job titles
- Companies
Product information may also change.
Regular data review helps businesses identify outdated records.
How Does the Data Cleansing Process Work?
A typical data cleansing process may involve several stages.
Step 1: Identify Data Quality Problems
The first step is to analyse the dataset and identify problems such as duplicates, missing fields, inconsistent formats, and incorrect values.
Step 2: Standardise the Data
Information is converted into a consistent format.
For example, addresses, dates, telephone numbers, and company names can be standardised.
Step 3: Remove Duplicate Records
Duplicate records are identified and reviewed before being merged or removed.
Step 4: Correct Errors
Obvious errors are corrected using reliable source information.
Step 5: Validate the Data
The cleaned dataset is reviewed to ensure that the information meets the required quality standards.
Step 6: Maintain Data Quality
Data cleansing should not necessarily be treated as a one-time activity. Regular reviews can help prevent databases from becoming inaccurate again.
What Is Data Validation?
Data validation is the process of checking whether information meets predefined requirements.
For example, a business may validate:
- Email address formats
- Telephone numbers
- Required fields
- Product SKUs
- Dates
- Postal codes
- Numerical values
Data validation is often used alongside data entry and data cleansing.

What Is Data Enrichment?
Data enrichment goes a step further by adding useful information to existing records.
For example, a B2B database may contain a company name and website but lack:
- Industry
- Company size
- Location
- Contact information
- Decision-maker details
Additional relevant information can be added to make the database more useful for sales, marketing, research, or business analysis.
Data enrichment should always be performed using appropriate and reliable sources and according to applicable privacy and data-protection requirements.
Why Businesses Outsource Data Cleansing
Managing large databases internally can require significant time and resources.
Businesses may choose to outsource data cleansing when they have:
- Large customer databases
- Outdated CRM records
- Duplicate records
- Multiple data sources
- Legacy databases
- Large product catalogues
- Data migration projects
- Limited internal resources
Outsourcing allows internal employees to focus on their core responsibilities while experienced professionals handle repetitive data management tasks.

Data Cleansing for eCommerce Businesses
eCommerce companies often manage thousands or millions of product records.
Product databases can contain:
- Product names
- SKUs
- Prices
- Descriptions
- Images
- Categories
- Attributes
- Stock information
- Manufacturer information
Over time, this information can become inconsistent or outdated.
Regular data cleansing can help businesses identify duplicate products, missing information, inconsistent attributes, and outdated product records.

Data Cleansing for Customer Databases
Customer databases are another common area where data cleansing is valuable.
A business may have customer records stored across:
- CRM systems
- Spreadsheets
- Email databases
- Sales platforms
- Accounting systems
- eCommerce platforms
Combining these sources can create duplicate or inconsistent records.
A structured cleansing process can help create a more consistent customer database.

Data Entry and Data Cleansing Often Work Together
Businesses don't always need to choose between data entry and data cleansing.
In many projects, they are part of the same workflow.
For example, when migrating an old customer database:
Step 1: Extract the existing data.
Step 2: Clean and standardise the records.
Step 3: Remove duplicates.
Step 4: Validate the information.
Step 5: Enter or import the cleaned data into the new system.
Step 6: Perform a final quality check.
Combining these processes helps businesses create a more accurate and reliable database.
