The dangers of poor data quality often start as minor issues, but their impact can lead to damaged customer relations, inaccurate analytics, and costly business decisions.
Businesses are making critical decisions based on information that is often incomplete, outdated, or just wrong. The worst part is that many companies don't even realize they have a problem until it's too late.
The fact is that poor data quality costs companies an average of $15 million annually, with some studies suggesting it may consume up to 25% of their potential revenue.
Let's talk about what poor quality data is and how it impacts day-to-day operations.
What is poor data quality?
Poor data quality isn't just about duplicated or inaccurate data. It can occur in various forms that block your business productivity.
Here are the most common types of bad data that can become expensive if left unchecked:
Inaccurate data: This occurs when information is fundamentally incorrect at the point of entry, like incorrect phone number formats, misspelled customer names, or incorrect product information. These inaccuracies directly lead to failed communications, shipping errors, and a breakdown of customer trust.
Incomplete data: This includes records that are missing essential fields, like a contact record that doesn't include an email address, a company record that has no industry type, or a sales opportunity that doesn't have an estimated close date.
Duplicate records: These are customers, leads, or products that are recorded more than once in your database. Duplicate records often happen because of a data entry mistake or when system integrations are not in place.
Outdated information: This is data that was once accurate but is no longer updated, like old titles, previous addresses, and information about former employees or discontinued products.
Inconsistent formatting: This is when the same information gets stored in different formats across systems or departments. For example, dates can be stored as MM/DD/YYYY or DD-MM-YY, and country names can be stored as acronyms or full names.
When bad data accumulates in your system or database, your data becomes inaccurate, leading to costly mistakes across your organization.
The real business impact of bad data
The consequences of poor data quality go beyond simple inconveniences. These issues get to the core of your business productivity.
Loss of revenue
Imagine your e-commerce site shows that an item is in stock due to a data syncing error. Your customers place orders for items that you can't fulfil, so you issue immediate refunds. This means failed purchases, abandoned carts, and a permanent loss of their trust—not to mention the cost of processing failed transactions.
Wasted time and resources
Think of a sales team getting a lead list with multiple entries for the same company. In that scenario, they waste hours making overlapping calls to different contacts, creating internal confusion, and annoying the lead instead of collaboratively closing the deal.
Did you know that SDRs (Sales Development Representatives) waste an average of 27% of their potential selling time following bad data? This means your most valuable revenue generators are spending more than two hours a day on dead ends rather than closing deals.
Damaged credibility and reputation
Due to duplicate entries for the same lead, your marketing automation platform might end up sending the same email twice to one person. At that point, you’re no longer seen as a potential partner; you’re treated as a spam. With AI now managing inboxes, this behavior can easily make an AI agent delete, unsubscribe from, or block your emails. That means even your future, well-meaning messages might never be read again.
Missed opportunities
A manufacturer's CRM system fails to identify a major client's multi-year contract nearing expiration. The sales team, unaware of the approaching renewal window, misses the important timing to re-engage. When your team isn't aware and doesn't act on time, competitors will seize the opportunity, even if you have a better product.
Poor decision-making
Imagine a scenario where your ecommerce order returns aren't updated. This can have a significant negative impact on the overall revenue and product performance reports, leading to poor decision-making.
These small errors severely impact your brand's reputation, raising red flags and lost deals due to low trust.
How to fix your data quality problems
The good news is that poor data quality isn't a permanent issue. Here are practical steps to transform your data into a strategic asset:
Automate data entry and validation
The more you can automate data entry, the fewer human errors you'll encounter. Implement systems that automatically flag or reject incomplete or inaccurate records when importing data from external sources.
Continuously monitor and clean data
Regularly audit your data to identify problems like inaccuracy, duplication, and outdated entries. Continuous monitoring eliminates stagnant or inactive data.
Prioritize critical data elements
Identify which data fields are the most critical for leads, contacts, accounts, opportunities, and billing. Focus your initial efforts on fixing them to ensure small wins that are important for ongoing commitment.
Use data governance tools
Invest in tools that help automate and enforce governance and standardization across your organization.
