The service analyses a company's commercial databases in order to provide a credible, benchmarked valuation of the asset.
Operationally the analysis also helps implement effective strategies to improve data quality standards, increase volumes of permission data, improve data security, drive value and enhance future profitability.
DQM said that data owners need to be aware of the quality of their data. If commercial and customer data has not been "fairly collected" then it may be illegal to continue using it.
Enquirers' email records may not be used unless they have overtly opted-in to being contacted.
Duplicate, out-of-date or inaccurate records lead to marketing inefficiency, customer or prospect annoyance and inaccurate management analysis. This leads to increased customer defection and poor return on investment from marketing plans and other business initiatives.
DQM also said that the adverse affect of poor customer and prospect data standards is magnified many times at the highly sensitive period pre or post a merger, an acquisition or a buyout.
Its data information pack audits a target company's database to check how it complies with the Data Protection Act, the European Directive on Privacy and Electronic Communications, the Direct Marketing Association's best practice and Information Security Best Practice.
The DQM service then subjects the customer database to a data hygiene and quality assessment, which hunts out businesses that have moved location, people who have died, firms that have ceased trading and duplicate records.
In addition it also offers the option for customers to have the value of their data independently measured as part of the Data Information Pack process.
Adrian Gregory, managing director of DQM Group, said: "Lack of return on investment from acquisitions has been regularly documented.
"But only now are financiers and trade buyers recognising how critical a part is played by quality, accuracy and legality when a commercial database is the principal company asset."
