orgaMAX ERP is the office and ERP software from deltra Business-Software GmbH, headquartered in Bielefeld, Germany. The product targets self-employed professionals, freelancers and small-to-medium-sized German Mid-Market businesses — typically 1 to 50 employees. The strategic positioning is "Buero plus Inventory Management from one source": a single integrated platform covering quoting, invoicing, accounting, order management, light warehouse and document management, so a small business doesn't have to glue together five disconnected tools. orgaMAX has been one of the long-running products in the German SMB segment, with a customer base that ranges from solo freelancers to small trade and services businesses.
Functional scope
orgaMAX bundles the typical SMB processes into one integrated platform. The order-processing module covers quotes and invoices with ZUGFeRD and XRechnung e-invoicing support, order templates, dunning and consolidated invoicing. Warehouse and stock are managed with movement-history, multi-warehouse capability for small set-ups, and basic batch tracking. CRM keeps customer master data, contact history and pipeline notes. The finance module covers AR/AP, bank-account import and a tax-relevant audit trail. The office-tools layer adds document templates, simple project tracking and time recording. For online retailers there are connectors to Shopify, WooCommerce, Shopware, Amazon and eBay, with order import, stock sync and tracking-info push-back.
Deployment
orgaMAX is offered in two variants: a classical on-premise Windows client-server installation, and a cloud variant operated from German data centres. Both variants use the same data model and support multi-user operation as well as multi-mandant (multiple legal entities under one licence). Cloud customers benefit from automatic update roll-out; on-premise customers receive updates through their maintenance contract. The choice between the two is typically driven by IT-strategy preferences and data-residency comfort rather than functional differences.
Target audience
orgaMAX targets self-employed professionals, freelancers and small-to-medium-sized businesses with typically 1 to 50 employees. Vertical concentrations are visible in trades (stationary and online), services, crafts, consulting, agencies, small wholesale and direct-selling businesses. The product is at its most defensible when the customer is replacing a sprawl of separate tools (an invoicing app, a CRM, a stock spreadsheet, a separate DATEV connector) with one integrated workspace.
DACH localisation and compliance
orgaMAX is built specifically for German SMB tax and finance workflow. DATEV integration — DATEV is the German cooperative of tax advisors whose data format is the SME finance-exchange standard — is native, allowing the customer's external accountant to receive posting data without manual re-keying. GoBD compliance — the German principles for proper digital bookkeeping that define audit-trail and archiving requirements — is addressed through standard archiving, redundant storage and data-processing-agreement support. ZUGFeRD and XRechnung e-invoicing are covered in line with the phased German B2B e-invoicing mandate. Cloud hosting is in German data centres, which is the default expectation for DSGVO-conscious SMB buyers.
Pricing and selection
orgaMAX uses a subscription model. The bookkeeping variant starts at approximately 12.95 euro per month, the ERP edition from approximately 49 euro per month, and the document module from approximately 9 euro per month, per mandant. Multi-user and module packages are licensed separately. The product's weaknesses become visible above approximately 50 to 100 employees with complex processes: production planning, deep service management and project controlling are limited. orgaMAX is most defensible for solo-to-small Mid-Market buyers; growing customers typically migrate to weclapp, myfactory or Sage 100 when the operational complexity outgrows the platform.

Fazit
orgaMAX ERP ist eine solide und ausgereifte Bürosoftware mit ERP-Charakter für Selbstständige und kleine bis mittelständische Unternehmen in Germany, Switzerland and Austria-Raum. Wer eine modulare Solution mit Inventory Management, Auftrag, Buchhaltung und Dokumentenmanagement aus einer Hand sucht und Wert auf deutsche Rechtsanforderungen, Cloud- oder On-Premises-Wahl und einen etablierten Hersteller legt, findet in orgaMAX einen pragmatischen Kandidaten. Bei größeren Mittelständlern mit komplexen Produktions-, Konsolidierungs- oder Multinational-Anforderungen sollten Suite-ERPs zusätzlich evaluiert werden. Insgesamt überzeugt orgaMAX vor allem durch das ausgewogene Verhältnis zwischen Functional scope und Einstiegsbarriere: Die Software ist in wenigen Tagen produktiv einsetzbar, lässt sich Schritt für Schritt um Module erweitern und ist sowohl für klassische Dienstleistungsunternehmen als auch für Onlinehändler:innen mit moderatem Auftragsvolumen ein realistischer Mittelweg zwischen reiner Buchhaltungssoftware und ausgewachsenem ERP.

Frequently Asked Questions
Is orgaMAX suitable for solo freelancers?
Yes. The bookkeeping variant at approximately 12.95 euro per month is built specifically for freelancers and self-employed professionals who need quoting, invoicing and DATEV-style bookkeeping in one tool without needing the full ERP scope.
Does orgaMAX support DATEV?
Yes. Native DATEV export is a standard part of the product, so the customer's external tax advisor receives posting data in the DATEV format — the cooperative of German tax advisors whose data layout is the de facto SME finance-exchange standard.
Can orgaMAX handle e-commerce orders from Shopify and Amazon?
Yes. Connectors to Shopify, WooCommerce, Shopware, Amazon and eBay automate order import, stock sync and tracking-info push-back. This makes orgaMAX usable for small to mid-sized online retailers who don't need a dedicated multi-channel platform.
When does orgaMAX hit its limits?
Above approximately 50 to 100 employees with complex production, deep service management or project controlling, orgaMAX gets stretched. Growing customers typically migrate to weclapp, myfactory or Sage 100 at that point.
