5.8/10German modular ERP software from Connectivity GmbH for project-based agencies, consultancies and IT service firms, covering CRM, time tracking, project control, invoicing and dunning.
Data last updated November 2026 · Our methodology
Overview
ConAktiv is business software built in Mannheim by Connectivity GmbH, which has been installing it since 1995. It is aimed at mid-sized companies that bill by project, mainly advertising and marketing agencies, management consultancies and IT service providers. The vendor sells separate editions for agencies, consultants and IT firms. ConAktiv brings address and CRM management, new-business acquisition, appointment and resource planning, time tracking and project controlling together with financial tasks. Those tasks include quotes, invoicing, email invoice delivery, invoice checks, dunning, a cash book and VAT handling. Software directory Softguide lists ZUGFeRD and XRechnung e-invoicing interfaces, multi-client and multi-currency support, and bookkeeping as an optional extra module. Booking data can be exported to DATEV, and reviewers also mention an SAP connection. You can run it on premises, in the cloud or in a browser, and there are clients for Windows, Mac and mobile. Licences are per named user and can be rented or bought outright. ConAktiv does not publish prices. Directories list rental from 29 euros per user per month, and Softguide cites a lower entry price of 9 euros per month. Buyers will need a quote. The main weakness is usability. On OMR Reviews, which averages 4.1 from 48 reviews, the interface is the most common complaint: users call it dated, slow and unintuitive, and some report crashes. Reviewers do praise support and the way the software can be customised.
