DZH

What DZH does

DZH Dienstleistungszentrale für Heil- und Hilfsmittelanbieter GmbH is a Hamburg-based private German GmbH, founded in 1944, that provides outsourced billing and administrative services to healthcare providers across three regulated German verticals: Pflege (care facilities including ambulatory care, intensive care, day care, and support services), Hilfsmittel (medical aids providers such as medical technology firms, sanatoriums, and orthopedic/shoe technology businesses), and Heilmittel (therapeutic service providers). Customers use DZH to handle the full reimbursement lifecycle with statutory health insurers — a process that is otherwise complex, slow, and document-heavy when run in-house. The company is led by Managing Directors Marcel Priester and Benedikt Steffen, with Stephan Losse serving as content-responsible officer, and operates with 51–100 employees.

The company's core technology is the Karla platform, a cloud-based, modular billing and administration suite. The core product, Karla.liquid, automates end-to-end customer invoicing and payment collection. It is extended by a suite of add-on modules: Karla.secure and Karla.secure+ handle resubmission of formally rejected claims and management of outstanding private-invoice collections; Karla.finance (also sold as DZH.finance) provides pre-financing so customers can receive funds at a chosen date independent of insurer payment cycles; Karla.world delivers an online status portal with invoice-correction detail; Karla.egeko manages electronic application and approval workflows for care services; karla.collect provides digital document archiving; and Karla.app delivers a mobile (iOS) view of billing and payment statistics. The platform also offers Telematikinfrastruktur connectivity for integration with the German healthcare digital infrastructure. The company holds a BaFin-supervised legal services registration under §10 Abs. 1 Rechtsdienstleistungsgesetz, which authorizes it to render collection-related billing services.

DZH operates a B2B service-delivery model: customers outsource billing operations to DZH on a transaction-fee basis rather than licensing standalone software. Go-to-market is direct, relying on a Hamburg headquarters, inbound phone/email consultation, content marketing through dzh-online.de, and downloadable product brochures. The company targets the German domestic market within the broader DACH region, has no disclosed funding rounds, no subsidiaries, and no parent company, and is privately held by its managing directors.

Direct peers

• DAVASO GmbH: German-headquartered software and service provider specializing in statutory health insurance (GKV) billing and reimbursement for Heilmittel, Hilfsmittel, and Pflege providers — the closest direct functional competitor to DZH's Karla platform.
• Helmsauer Gruppe: German medical billing and receivables-management group serving physicians, hospitals, and care providers — directly comparable as a billing-outsourcing and pre-financing peer for the same GKV customer base.

Broad incumbents

• CompuGroup Medical (CGM): One of Europe's largest healthcare-IT vendors offering practice management, EHR, and billing modules to ambulatory and care providers; competes with DZH as a broad suite rather than a focused billing specialist.
• medatixx GmbH: German provider of practice-management software (medatixx) used by physicians and therapists, including integrated billing/EDIFACT modules; competes with DZH in Heilmittel and Hilfsmittel provider workflows.
• Dedalus Group: European healthcare-IT vendor (with strong German presence) delivering hospital, radiology, and ambulatory-care software including billing; an incumbent overlapping with DZH's care-provider customer base.
• Arvato (Bertelsmann) Healthcare: Large-scale BPO arm of Bertelsmann providing back-office, billing, and customer-service operations including healthcare payer-provider services; competes with DZH for outsourced reimbursement work at larger scale.

Emerging players

• zollsoft GmbH: German maker of "easymed" practice and billing software for Heilmittel/Pflege providers; competes with DZH on integrated clinic-management workflows and statutory-insurance billing.
• samedi GmbH: Berlin-based provider of online appointment scheduling and care-process platforms for German providers; adjacent emerging player connected to the same Telematikinfrastruktur ecosystem DZH serves.

Regional players

• PVS dental GmbH: Privatärztliche Verrechnungsstelle focused on dental/medical receivables management in Germany; comparable business model of outsourced billing and pre-financing, but in a different specialty vertical.

Others

• DATEV eG: German cooperative providing accounting, tax, and ERP software used by SMB providers; adjacent because many of DZH's care-facility customers run DATEV for accounting and could converge billing into that stack.
