The market will change completely in the coming years and Service Providers, companies and tax authorities need to review their strategy.

M&A strategy

It is estimated that there are currently already more than 1.000 providers of electronic invoicing services - in Europe alone. Due to the increasing obligation to send and receive electronic invoices in many countries, these numbers are growing almost daily. With an estimated market volume of several billion euros, e-invoicing is one of the most attractive and dynamic markets of all.

This means that market consolidation is inevitable. If you are looking to buy or sell a company in the e-invoicing sector, we are your ideal partner. With its comprehensive know-how of globally active service providers, billentis is predestined to accompany this process. billentis supports both service providers and private equity or venture capital companies in the selection of suitable providers through to successful post-merger integration.
