PART C.One

PART C.One is a vertical industry solution from PART, a long-standing German SAP partner, built as an extension on SAP Business One. The product targets DACH Mid-Market process manufacturers — the broad mid-market segment of German-speaking SMBs — in chemicals, pharmaceuticals, cosmetics and food. By riding on SAP Business One, customers get the SAP architectural foundation (HANA reporting, app platform, established data models) plus PART's industry-specific extensions for recipe management, batch and serial-number traceability, and quality-management workflows that match the regulatory and operational reality of process production.

Industry functions

C.One adds substantial industry-specific functional blocks on top of SAP Business One. The recipe management module handles complex recipes with quantities, tolerances, substitution rules and yield management. Comprehensive batch and serial-number management ensures that every produced unit can be traced back to its raw materials and forward to the end customer — mandatory in regulated food, pharma and cosmetics production. Quality management covers inspection plans, sampling, certificate-of-analysis generation and deviation handling. Production planning is recipe-aware rather than discrete-BOM-aware, which is what distinguishes process manufacturing from machinery and assembly.

Target audience

C.One targets mid-market process manufacturers in chemicals, pharmaceuticals, cosmetics and food. These verticals share complex recipes, strict regulatory requirements, batch-and-serial traceability obligations and tight quality-control workflows. Sweet-spot company size is approximately 50 to 500 employees with multiple production lines. Smaller process manufacturers can sometimes get by with a generic ERP plus spreadsheets; above 500 employees customers typically migrate to SAP S/4HANA with deeper process-industry extensions.

SAP architecture and deployment

Because C.One sits on SAP Business One, customers benefit from the full SAP architecture including HANA-based reporting, the SAP app platform and established data models. Deployment runs on two main paths: classical on-premise installation on customer infrastructure, or cloud-hosted on SAP-partner data centres. The Business One platform is well-established in DACH Mid-Market: licensing is per named user with standard SAP maintenance, and the SAP partner ecosystem provides consulting and operational depth that smaller proprietary platforms cannot match.

DACH localisation and DATEV

SAP Business One's German localisation is mature. DATEV integration — DATEV is the cooperative of German tax advisors whose data format is the SME finance-exchange standard — is supported through standard exporters and partner add-ons, so the customer's external accountant can continue working in DATEV. GoBD compliance — the German principles for proper digital bookkeeping — is covered through Business One's audit-trail and archiving features. ZUGFeRD and XRechnung e-invoicing are supported in line with the phased German B2B e-invoicing mandate. For multinational process-industry groups, Business One's multi-currency and multi-language support carries the load.

Pricing and selection

C.One pricing combines SAP Business One licences (per named user) with the C.One industry extensions, plus annual maintenance contracts and hosting packages if cloud-operated. PART operates with a deep consulting bench experienced in process-industry implementations — the consulting depth in chemicals, pharma and food is one of the meaningful selection signals. Competitors at this segment include other SAP Business One process-industry add-ons, oxaion, abas ERP with process extensions, and at the smaller end specialist vertical ERPs. The strongest selection signal is a process manufacturer who values the SAP platform's ecosystem alongside genuine industry depth.

Strengths and limitations at a glance

Vertical extension on SAP Business One with the SAP brand, partner ecosystem and Mid-Market pricing model.
Process-manufacturing depth — recipes, batch genealogy, weighing-station integration, MHD (best-before) management.
HANA Cloud option provides modern in-memory backbone where required.

Considerations:

Outside addressed process verticals the value of the C.One extensions is limited.
SAP Business One licensing and indirect-use rules add complexity versus DACH-native Mid-Market ERPs.
Single partner (PART) for the extension creates concentration risk on consulting.

Best-fit profile and comparable vendors

Best-fit customers are DACH process-manufacturing Mid-Market businesses of 30 to 300 users in chemicals, cosmetics, food and pharmaceuticals already inclined toward an SAP-branded stack. Comparable vendors include SAP Business One directly, Poly.ERP for adjacent plastics, and CSB-System for food and meat. The ERP for pharma notes are useful for regulatory framing.

Häufig gestellte Fragen

Which modules does PART C.One offer?

PART C.One typically includes modules for financial accounting, order management, warehouse, purchasing and master data. Industry-specific extensions (PPS, CRM, DMS) are often optional — the vendor profile above shows the exact scope of functions. The exact arrangement depends on the industry, company size class and customising depth of the specific ERP setup.

What hardware requirements does PART C.One have?

For cloud deployment, modern browsers are sufficient. For on-premises installations, server requirements vary with the number of users and document volume — the vendor provides detailed system requirements, often with recommended configurations for 25, 50, 100 or 250 users. The exact arrangement depends on the industry, company size class and customising depth of the specific ERP setup.

How does data migration from an old ERP to PART C.One work?

Data migration typically runs in 3 phases: mapping (old vs new data model), cleansing (duplicates, master data quality), and a test migration with validation. Specialised migration service providers can be found under ERP integration providers. The exact arrangement depends on the industry, company size class and customising depth of the specific ERP setup.

How expensive is annual maintenance for PART C.One?

On-premise maintenance typically runs at 18–22% of the licence costs per year and covers updates, hotfixes and phone support. Cloud ERPs include maintenance in the subscription price, so there is no separate maintenance contract. Over a typical system lifetime this recurring cost adds up to a significant share of the total cost of ownership, so budget for it from year one.

Which well-known reference customers does PART C.One have?

Vendors usually list reference customers on their own website — for specialised industry ERPs, 10–50 showcase customers are well known. Industry-specific references should be requested specifically before making a selection. The exact arrangement depends on the industry, company size class and customising depth of the specific ERP setup.
