OOURS

OOURS is the ERP and Inventory Management (merchandise-management) product from sinobit GmbH, headquartered in Norderstedt near Hamburg. The company was founded in 1999 and built its reputation over more than two decades as the most prominent supplier of Mac-capable business software in DACH (Germany, Austria, Switzerland), previously under the McBüro brand. OOURS targets the German Mid-Market SMB segment with a notable cross-platform footprint: native clients on Mac, Windows and iOS, built on a FileMaker-based architecture. The product's dual positioning — generic SMB ERP plus several long-tenured vertical specialisations — is uncommon in the DACH market and a legacy of the long McBüro customer relationships.

Functional scope

OOURS combines classical merchandise management with modern CRM and office capabilities in a single integrated platform. The modular architecture lets customers grow from a lean invoicing-and-CRM setup into a full Inventory Management with inventory, financial accounting and project management. The product covers quote-to-invoice, customer and supplier management, inventory and warehouse, basic production for assemblies, project accounting, time tracking and document management. ZUGFeRD and XRechnung e-invoicing are supported in line with the German B2B e-invoicing mandate.

Cross-platform architecture

The single most distinctive feature of OOURS is genuine native support for Mac, Windows and iOS. Where almost every other DACH Mid-Market ERP is Windows-first, OOURS uses a FileMaker-based architecture that delivers native clients on all three platforms with feature parity. For agencies, studios, publishers and small specialist businesses that have standardised on Mac hardware, this avoids the painful workarounds (VMs, Citrix or Parallels) that other ERPs would force on them. The OOURS Mobile app on iPhone and iPad extends master data, orders and customer information to field-service and external sales scenarios.

Target audience and verticals

OOURS targets small to medium-sized companies in DACH. The legacy McBüro customer base gives it unusual vertical depth in publishing, graphics, agencies, trades, services and small manufacturers. This breadth means OOURS competes both with generalist SMB ERPs (Lexware, sevDesk, weclapp) and with vertical specialists for trades and publishing — with the cross-platform support and FileMaker-based customisation as the main differentiators.

DACH localisation and compliance

OOURS is Made-in-Germany software with German development, support and hosting. GoBD-compliant document archiving — GoBD being the German principles for proper digital bookkeeping — is part of the standard product. DATEV export (DATEV is the cooperative of German tax advisors whose data format is the SME finance-exchange standard) is supported through dedicated connectors. Role-based permissions, multi-tenant operation and revision-safe document archiving are standard. Hosting can be on customer premises, in the customer's data centre or with specialist FileMaker hosters in Germany; for GDPR-compliant data-processing arrangements, German hosting is the default choice.

Vendor and selection

sinobit provides consulting, implementation, training and support directly, supplemented by a partner network in the FileMaker ecosystem. The small-house structure delivers personal accountability and short lines of communication; the trade-off is a smaller resource base than a major ERP vendor would offer. OOURS was awarded the Innovationspreis-IT 2017 for Schleswig-Holstein and carries the BITMi Software-Made-in-Germany 2023 seal. Licensing is available as classical perpetual licence with maintenance, or as a subscription/rental model; the platform competes with Lexware, sevDesk, weclapp and vertical specialists.

Strengths and limitations at a glance

Native cross-platform Mac and Windows support — rare in DACH ERP and meaningful for creative, agency and design-led SMBs.
Long-running product history under sinobit GmbH since 1999 with continuous evolution.
Solid DACH compliance profile including GoBD-aligned audit-trail and DATEV export.

On the other side:

Smaller install base and partner network than horizontal Mid-Market ERPs.
Production-MRP and warehouse depth are lighter than dedicated manufacturing or distribution ERPs.
Cloud option exists but the product's historical centre of gravity is desktop installation.

Best-fit profile and comparable vendors

Best-fit customers are DACH SMBs of 5 to 100 employees in trade, light services and design-led businesses with Mac-first or mixed-OS desktop estates. Comparable vendors include weclapp for cloud-first SMBs, Lexware for the smallest end of the market, and orgaMAX for office-and-invoicing focus. A read of the ERP for small business overview is useful for sizing the requirements.

Häufig gestellte Fragen

How long does it take to implement OOURS?

An ERP implementation takes 3 to 18 months depending on complexity. Cloud solutions are often productive within 4–12 weeks, while classic mid-market ERP systems need 6–12 months for requirements analysis, customising, data migration and training. Read more at ERP implementation.

How secure is OOURS in terms of data protection?

For cloud ERP systems, the server location (ideally EU/DE), a data processing agreement (AVV) and BSI C5 or ISO 27001 certifications are key criteria. GDPR compliance should be explicitly documented by the vendor. The exact arrangements depend on the industry, company size and customising depth of the specific ERP setup.

How is OOURS being further developed?

Cloud ERP systems typically receive monthly to quarterly releases automatically. On-premises ERP systems have annual major releases with active patch maintenance. Release notes and the roadmap can be viewed at the vendor.

What happens to my data if I cancel OOURS?

With cloud ERP systems, a good provider guarantees data export in an open format (CSV, JSON, SQL dump). The contract should explicitly regulate the data return obligation, deletion period and format. The exact arrangements depend on the industry, company size and customising depth of the specific ERP setup.

What support SLAs does OOURS offer?

Standard support usually covers weekdays from 8 a.m. to 6 p.m. with a response time of around 4 hours. Premium/24x7 SLAs come at an extra charge. With cloud providers, availability SLAs (e.g. 99.9%) are important – check the contract!
