Synapcus
Synapcus is an integrated cloud platform that combines ERP, CRM, project and HR management with a clear vertical focus on the architecture, engineering and construction (AEC) industry. Where horizontal ERPs treat project business as one workflow among many, Synapcus is purpose-built for the project-driven economics of AEC firms: time-and-materials project structures, multi-discipline staffing, deep post-calculation, change-order management and the specific compliance and document workflows of architecture and engineering services. The vendor positions Synapcus as a vertical specialist in the DACH AEC market and competes mainly with project-business specialists such as Vertec and Projektron rather than with horizontal Mid-Market ERPs.
Functional scope
Synapcus covers the full project-driven business cycle of an AEC firm: opportunity and bid management in the CRM module, project structuring with multi-discipline work-breakdown, resource planning across architects, engineers and project managers, time and expense capture with mobile entry, project controlling with deep post-calculation against bid budgets, change-order management with documented client approvals, invoicing on time-and-materials, milestone or HOAI fee-based logic, and finance-module integration. The HR module covers the typical AEC payroll, qualifications and certifications workflows. The depth of project controlling and the HOAI-aligned invoicing logic are the functional differentiators versus horizontal ERPs that handle project business as a generic module.
Target segment
The natural Synapcus customer is a German Mid-Market AEC firm — architecture office, engineering consultancy, construction-project planner or specialist-discipline engineering business — with typically 20 to 500 staff and a project-led economics model. The vertical depth means the product is not the right fit for trade, manufacturing or services organisations outside AEC; for those, horizontal Mid-Market ERPs deliver better value at comparable cost. Within the AEC vertical, Synapcus competes mainly with Vertec for the consultancy-services overlap and with KobiCom, projectfacts or similar AEC-leaning project-business tools. At the upper end with international consolidation needs, the AEC-vertical modules of SAP, Oracle or Microsoft are typical alternatives.
Architecture and deployment
Synapcus is delivered as a cloud-native platform hosted in European data centres, with browser-based access and a responsive layout for mobile usage. The vendor offers a private-cloud or hosted-managed deployment for customers with specific compliance requirements. The platform is built around an integrated data model that links the CRM, ERP, project and HR modules without the connector-based architecture typical of best-of-breed AEC stacks, which reduces integration complexity and the data-quality risks that arise from synchronising the same client or project record across multiple systems. Integration with CAD platforms, BIM systems, DATEV and common DMS products is supported through documented interfaces.
Pricing and TCO
Synapcus is sold under a per-user subscription model with modular scoping. As a directional benchmark for a 50-user AEC firm with the full ERP, CRM, project and HR perimeter activated, the annual subscription typically lands between 60,000 and 150,000 euro, with implementation services in a similar order of magnitude depending on customisation depth and data migration complexity. The five-year total cost of ownership is competitive with the comparable scope on a horizontal Mid-Market ERP plus a project-business satellite, and substantially below the integrated AEC modules of SAP S/4HANA or Oracle Fusion. The trade-off is the smaller partner network and the more focused ecosystem of third-party extensions.
Selection considerations
Synapcus is a strong choice for German Mid-Market AEC firms that want an integrated platform purpose-built for the project-driven economics of architecture and engineering services, with HOAI-aligned invoicing logic and deep post-calculation depth. The vertical focus is the competitive moat versus horizontal ERPs that handle project business as a generic module. The trade-offs are the smaller vendor profile, the more focused partner network and the dependency on a vertical specialist's long-term roadmap. For organisations outside AEC, Synapcus is not the right product. For AEC firms outside DACH, the local AEC specialists (Deltek for North America, BST Global for international engineering) are usually more appropriate.

Frequently Asked Questions
Who is Synapcus designed for?
Synapcus is designed for German Mittelstand AEC firms — architecture offices, engineering consultancies and construction-project planners — with typically 20 to 500 staff and a project-led economics model. The product is a vertical specialist rather than a horizontal Mittelstand ERP.
Does Synapcus support HOAI fee structures?
Yes. The invoicing module supports the HOAI fee-based logic used by German architecture and engineering firms, alongside time-and-materials and milestone-based invoicing for international or non-HOAI projects. The HOAI-aligned logic is one of the functional differentiators versus horizontal ERPs.
Is Synapcus cloud-only?
Synapcus is delivered as a cloud-native platform hosted in European data centres. A private-cloud or hosted-managed deployment is available for customers with specific compliance requirements. On-premises in the traditional sense is not the deployment model.
