Why does data cleansing suddenly become a problem on projects?

It’s completely normal for data issues to surface once a project gets going. Early on, everyone assumes the data is good enough. As soon as you start a migration, new reporting, analytics or AI, hidden duplicates, gaps, misaligned fields and conflicting records are exposed. That’s when timelines come under pressure and data cleansing suddenly becomes your problem.

What types of systems and data can you cleanse?

We work with data from CRM, LMS, finance, ERP and other operational systems, as well as spreadsheets and CSV exports. Most clients come to us with multiple systems that don’t agree with each other. Our approach is designed to reconcile, restructure and clean that combined dataset so it is consistent, reliable and ready for reporting, migration, analytics or AI.

How does your data cleansing process work?

We start with a short consultation to understand your project, systems, volumes and timelines. Then we profile a sample of your data to find the real issues. Next, we run tailored algorithms in cycles to fix structural problems, duplicates and inconsistencies, working collaboratively with you where human context is needed. Finally, we deliver a clean, structured dataset and walk you through what has been fixed and how to keep it clean going forward.

Can you help make our data ready for analytics and AI?

Yes. A big part of our work is getting data ready for analytics and AI projects. Clean, well-structured data is the foundation for reliable dashboards, predictive models and AI use cases. Our data cleansing focuses on consistency, structure and completeness so that your analytics, reporting and AI models behave as expected instead of amplifying bad data.

Do you offer any guarantee on your data cleansing work?

We offer a 100% data cleansing guarantee. We’ve seen messy data across many sectors and very little surprises us. If we agree to take your dataset on, we stand behind the outcome. If something isn’t right, we fix it at no extra cost. The goal is simple: you end up with clean, reliable data you can trust for your project.

What if I don’t know my exact data volumes yet?

You don’t need perfect information before talking to us. In the Data Health Check, we’ll look at where your data lives, typical record counts and how it is being used today. From there we can estimate scale, highlight risks and propose a practical, staged approach to cleansing that fits your timelines and budget.

What Clients Say

Rob Pearce, Data Manager, HIT Training Ltd

Rob, mid-market client sharing his data cleansing success story

“Our data cleansing was slowing us down. We’d spent 6 weeks manually fixing data across CRM, LMS, and finance. Every time we solved one problem, we found more. Our regulatory deadline was at risk.

Shaffiq’s team rebuilt our dataset properly and quickly, resolving the inconsistencies. We estimated it’d take us 960 hours, they did in 40.

They also showed us how to keep our data clean and track data quality. That reliable data is the reason our project finally moved forward, and it gave us a much clearer view of our data.”

Client Testimonial : Data Cleansing Success Story

It’s time-consuming

Manual data cleansing is slow, painful, and usually underestimated. You start with good intentions, but small slips snowball until your project needs clean data.

Multiple data sources

Spreadsheets make it worse. Multiple systems make it worse again. And that’s when projects stall - deadlines slip, teams get frustrated, and momentum disappears.

Why Data Cleansing Suddenly Becomes a Problem

Hidden and unknown

That’s where Rob’s team found themselves. Weeks of fixes, but the deeper they went, the more issues appeared. It wasn’t a lack of effort on their part.

Messy and misaligned

Robs dataset was complex and misaligned across CRM, LMS, and finance systems. This kept creating new problems every time they tried to fix one systems data.

Tight deadlines

Rob approached us through an introduction. He’d a tight deadline, and stalling. Using smart data science and years of experience, we rebuilt their data properly and quickly.

Keeping it clean

And it worked - Rob’s project finally moved forward with clean, reliable data they could trust. And best of all. We showed them how to keep that way themselves.

Common Data Issues Fixed

Here’s a list of common issues that show up in almost every data project. All normal, and fixable using purpose-built algorithms for your unique situation.

Duplicates & Conflicts

Duplicates appear across systems and spreadsheets, causing confusion. Easily identify, combine and correct conflicting entries to create one dataset.

Free Text & Structure

Notes, comments and descriptions hide details that structured systems cannot efficiently analyse. We’ll extract and reshape unstructured text so it’s information you can use for powerful new insights.

Inconsistent Naming

Names, dates, addresses, units and codes end up different across systems, creating mismatches. Let us align and format data so your systems match cleanly and operate effectively.

Legacy System Quirks

Old ERPs and CRMs leave behind odd layouts, truncated fields and outdated rules. Your bespoke-built routines clean and remodel legacy data so it powers insights.

Missing or Incomplete

Missing emails, codes, values, contacts and dates continually cause reporting failures and migration issues. Accurately complete, infer or standardise essential fields so information becomes reliable for everything.

Multiple Systems

Your CRM says one thing, the finance system says another, spreadsheets say something else. Seamlessly synchronise and align every sources into consistent datasets across AI and analytics.

Invalid or Outdated

Old contacts, closed sites, wrong categorisation, bad codes they create noise. Quickly identify invalid entries and clean them properly at scale, faster.

Complex Data

Field mismatches, schema gaps and unusual formats often stop migration tools and halt progress. Carefully reshape, validate and configure all structures so migrations proceed smoothly without unnecessary risk.

Data Readiness for AI

Incomplete or irregular data breaks AI and analytics models, including dashboards. Get reliably prepared information so analytics and machine learning deliver accurate results.
