TOPIX is an integrated business suite developed in Germany that combines ERP, CRM, financial accounting, HR and document management in a single application. The product is notable in the DACH ERP market for one specific reason: it runs natively on both macOS and Windows, which is unusual in a category dominated by Windows-centric Mid-Market vendors. Headquartered in Munich, the vendor has built a customer base of several thousand DACH businesses with a particularly strong adoption in creative agencies, design studios, architecture and engineering offices and professional services firms where Mac penetration is high. The functional positioning is the SMB and lower-Mid-Market integrated-suite segment, competing with horizontal Mid-Market ERPs that typically force Mac-using organisations onto Windows or into a thin-client workaround.
Functional scope
TOPIX covers the integrated SMB suite perimeter: CRM with account, contact and activity management, sales-order processing with quoting and invoicing, multi-warehouse inventory with batch and serial-number tracking, project management with time-and-materials tracking, financial accounting with GoBD-aligned bookkeeping and DATEV integration, HR with payroll preparation, and integrated document management. The depth of each module is appropriate for the SMB and lower-Mid-Market segment rather than for upper-Mid-Market industrial use cases — advanced manufacturing, complex variant configuration and large multi-entity consolidation are not the product's primary territory. The cross-platform Mac-and-Windows native execution and the integrated DMS are the most distinctive functional features.
Target segment
The natural TOPIX customer is a German SMB or lower-Mid-Market organisation between roughly 5 and 100 users with significant Mac penetration. Typical verticals include creative agencies, design studios, architecture and engineering offices, professional services firms, consultancies and similar service-led businesses. The cross-platform foundation is most attractive for organisations that have made a strategic choice for Mac in production roles and do not want to maintain a separate Windows environment just for the ERP. The product is less competitive in pure-Windows organisations or in manufacturing and warehouse-heavy trade scenarios where the horizontal Mid-Market ERPs deliver more vertical depth. At the upper end above 100 users, larger DACH Mid-Market ERPs typically provide more scale.
Architecture and deployment
TOPIX runs natively on both macOS and Windows clients with a shared back-end. The product is delivered as an on-premises installation or as a hosted managed service through the vendor, with a cloud-hosted multi-client option for smaller organisations. The native Mac client is the architectural differentiator: most Mid-Market ERPs use a Windows-only thick client or a thin web client that delivers a degraded experience on Mac. TOPIX maintains feature parity across both client platforms, which is the operational basis for the product's positioning in Mac-heavy organisations. Integration with DATEV, banking, shipping carriers and common DMS platforms is part of the standard product.
Pricing and licensing
TOPIX is sold under both perpetual licensing with annual maintenance and per-user-per-month subscription pricing depending on the deployment model. Indicative pricing for the subscription model: the entry tier begins at around 40 euro per user per month for the basic ERP/CRM scope, with higher tiers up to around 100 euro per user per month for the full suite including HR, payroll and advanced DMS. Implementation services are charged separately on a project basis but are typically modest because the standard product covers most SMB workflows without heavy configuration. Total cost of ownership over five years for a typical 25-user deployment lands between 60,000 and 150,000 euro depending on tier and customisation, which is competitive with comparable DACH Mid-Market suites for the same functional scope.
Selection considerations
TOPIX is a strong choice for German SMB and lower-Mid-Market organisations with significant Mac penetration that want a single integrated suite covering ERP, CRM, finance and DMS without forcing Mac users onto a degraded experience. Creative agencies, design studios, architecture and engineering offices and professional services firms are the archetypal customers. The trade-offs are the focused functional scope — TOPIX is not the right product for manufacturing, warehouse-heavy trade or upper-Mid-Market industrial use cases — and the smaller vendor profile compared with the larger DACH ERP vendors. For Mac-heavy DACH service businesses below 100 users, TOPIX is one of the most appropriate options and is often the deciding factor when the alternative is forcing a Mac-using team onto Windows.

Who is the typical TOPIX customer?
A German SMB or lower-Mittelstand organisation between 5 and 100 users with significant Mac penetration. Typical verticals are creative agencies, design studios, architecture and engineering offices and professional services firms where Mac adoption is high.
Is TOPIX a cloud product?
TOPIX is delivered as on-premises installation, hosted managed service or cloud-hosted multi-client deployment depending on the customer's preference. The native client architecture is the technical foundation across all deployment models.
