accelent — Microsoft Business Central Partner and MEGABAU Provider
accelent GmbH (part of the Network Dimensions group) positions itself in the German-speaking market as a specialist Microsoft partner for mid-market ERP projects, going to market with the MEGABAU industry solution that sits on top of Microsoft Dynamics 365 Business Central. Where Business Central provides the technical foundation, accelent layers construction-specific workflows, calculations and documents on top. The product targets construction businesses across multiple trades — classical building and civil engineering, general contractors, scaffolding firms, mechanical and plumbing trades, and steel-construction businesses. Specialist trade media and Microsoft partner directories list accelent as a long-running implementation and vertical-industry partner; the company itself cites roughly twenty-five years of market presence and support for more than forty industry standards including GAEB, OENORM and VOB.
Overview
accelent is positioned between a technical Microsoft platform and a deep functional construction-ERP solution, which is a model that has proven itself across the German Mid-Market (mid-market) for vertical-industry coverage. The vendor relies on the Microsoft platform for upgrade reliability, DACH localisation and ecosystem reach, while building its own industry-specific competitive position through depth of construction know-how. The combination is comparable to other Business Central industry-partner plays such as acadon for timber or KUMAVISION for manufacturing — the buyer chooses both the underlying ERP platform and the vertical-industry team in a single decision.
Functional sweet spot
MEGABAU covers the typical processes of a construction business along the project lifecycle. The core consists of calculation, bill-of-quantity (Aufmass) capture, billing and project management, complemented by purchasing and subcontractor management, inventory and equipment management, and financial accounting and controlling on the Microsoft Business Central base. Users can import bills of quantity through GAEB and OENORM interfaces, perform quantity and price calculations, manage variation orders (Nachtragsmanagement) and produce progress and final invoices according to VOB/B — the German construction-contract regulations. Mobile capture of quantities, hours and equipment use is supported online and offline through dedicated apps. Industry-specific topics such as building-element management, tool and machinery management, site diaries and safety briefings are covered. Open Microsoft interfaces support third-party CAD, calculation, document management and HR tools.
DACH positioning
accelent is engineered for German construction businesses: support for GAEB (the German exchange standard for tendering and contracting in construction), OENORM (the Austrian standards body) and VOB (the German construction contract regulations) is central to the value proposition rather than an extension. The Business Central foundation provides standard DATEV (the German accounting exchange standard) integration, GoBD (digital-bookkeeping) compliance, ZUGFeRD and XRechnung e-invoicing without bespoke development. The reference base sits in Germany and Austria with selected Swiss customers. The competitive set is mainly other construction-specific ERPs such as Nemetschek Bau-Software or BRZ in the DACH market — accelent competes through the combination of Microsoft platform standards with depth of construction know-how.
Pricing and implementation
MEGABAU follows the standard Microsoft Dynamics 365 Business Central licence model, with the accelent industry extension priced as a separate per-user subscription. The vendor does not publish list prices: total cost depends on user count, module scope and operating model, and stacks on top of the Business Central licence cost. Implementation is delivered directly by accelent, which keeps the project chain short and ensures consistent transfer of construction-industry knowledge. Total cost of ownership stacks the Business Central platform cost on top of the MEGABAU extension — more expensive than a generic Business Central but typically far cheaper than customising Business Central to construction-industry depth from scratch.
Selection considerations
accelent with MEGABAU is a defensible shortlist entry for DACH construction businesses, general contractors, scaffolding firms, mechanical-and-plumbing trades and steel-construction businesses that already plan to use Microsoft Dynamics 365 Business Central and want a productised construction-industry extension rather than a custom build. It is less compelling for non-construction buyers (generic Mid-Market ERPs fit better), for very small craft businesses without project-volume to justify the Business Central platform, or for buyers that prefer non-Microsoft construction ERPs such as Nemetschek Bau-Software or BRZ. The defining buyer profile is a German Mid-Market construction company with project-volume scale that values the Microsoft platform standards alongside vertical-industry depth.

Fazit
accelent verbindet mit MEGABAU eine global etablierte ERP-Plattform mit einer fachlich tiefen Industrieslösung für die Bauwirtschaft – und schließt damit eine Lücke zwischen reinen Standard-ERP-Implementierern und vertikal spezialisierten Bau-ERP-Vendorsn. Für mittelständische Bauunternehmen, die Wert auf eine Microsoft-zentrierte Systemlandschaft, Cloud-Deployment und schrittweise Erweiterbarkeit legen, ist accelent ein ernstzunehmender Kandidat. Wer ein vollständig spezialisiertes Bau-ERP mit eigenständiger Plattform sucht, sollte alternative Vendors aus dem Bau-Spezialsegment in die Vorauswahl aufnehmen und idealerweise mehrere Optionen über strukturierte Anforderungsprofile und einen erfahrenen ERP Selection-Consultant vergleichen.

Frequently Asked Questions
Is MEGABAU a standalone construction ERP or an extension to Microsoft Dynamics 365?
MEGABAU is an industry extension to Microsoft Dynamics 365 Business Central. Business Central delivers the ERP core (financials, sales, purchasing, basic inventory) and the accelent MEGABAU extension adds the construction-specific functionality on top.
Which construction standards does MEGABAU support?
GAEB and OENORM for tendering and bill-of-quantity exchange, and VOB/B for German construction-contract billing rules, are part of the standard product. The vendor cites support for more than forty industry standards across the construction trades it targets.
How does accelent compare with Nemetschek Bau-Software or BRZ?
Both Nemetschek and BRZ are specialist DACH construction-ERP vendors with their own technology stacks. accelent differentiates by sitting on top of Microsoft Dynamics 365 Business Central, which means customers inherit Microsoft's upgrade cycle, DACH localisation and ecosystem rather than a vendor-proprietary stack. The choice often comes down to whether the buyer prefers a Microsoft-platform-aligned architecture or a fully vertical specialist.
