Data quality and cleaning for SMEs in Belgium
Identification of duplicates, correction of errors, and standardisation of your databases, so your tools finally work on reliable information.
A client database
turned into a mess.
Over the years, your contact database accumulates duplicates: the same client recorded twice with different spelling, an old address never removed, a phone number entered in formats that do not match from one file to another.
An email campaign that fails for a portion of recipients, a sales follow-up sent twice to the same client, a report that counts a company as two distinct clients: these small incidents almost always stem from the same root, a database that has never been cleaned since its creation.
Building a dashboard or connecting two software tools on a messy database is like building on sand. Cleaning is not an aesthetic detail; it is the condition for the rest of your digital tools to work correctly.

Free assessment
Thirty minutes to evaluate the state of your database and the problems that hinder you most daily.
Detailed proposal
Selected cleaning rules, scope of the affected databases, realistic timeframe, and detailed price excl. VAT.
Cleaning & deduplication
Application of validated rules, merging of duplicate files, and correction of inconsistent formats.
Follow-up
Implementation of regular checks so that the database remains clean after our intervention.
Reproducible rules,
not manual sorting.
Cleaning relies on matching rules that we define with you, then on scripts that apply them uniformly to your entire database, rather than manual file-by-file sorting which would be incomplete and time-consuming to redo.
Processing is carried out on secure environments located in Europe, with a backup copy of your original database retained before any modifications are made.
The price depends on the volume of files to process, the number of sources to match, and the complexity of the rules to apply. The free assessment gives you a clear estimated quote.
Does your database
need this cleaning?
Data quality & cleaning
Businesses whose client or supplier database accumulates duplicates, empty fields, and formats that no longer match.
If your company is starting with a small and already clean database, this work brings no added value for now.
A typical example
of a restored database.
Take a distributor who imports its suppliers' catalogues several times a year, each in a different format. This is an illustrative example, built from the requests we regularly receive for this type of situation.
After several successive imports, the same item appears under multiple references in the management system. The matching rules established during cleaning make it possible to merge these duplicates and prevent them from reappearing at the next import.
What people ask us
about data cleaning.
No, merging rules keep the history of the two original files. Nothing is deleted without you having validated the applied rule.
With control rules in place, a database stays clean longer. Periodic review remains useful if you regularly import new data.
We define them with your team, as only you know whether two similar files truly refer to the same client or two distinct clients.
Yes, this is often where cleaning brings the most value, when the same contacts exist across your CRM, accounting, and email systems.
