PROWERB assembles, finishes and dispatches promotional products, mailings and campaign goods using documented processes. The operation grew from the lettershop founded in 1979 and now combines in-house presses, ERP control and a negative CO₂ balance.

Kitting & Assembly and Co-Packing: 1 to 15,000 Assemblies per Day
Lettershop & Mailing: GDPR-compliant with a DPA
Co-packing by bill of materials, booked in the proprietary enterprise resource system. Finishing happens in-house — flocking, transfer printing, embroidery, screen printing and direct-to-garment printing, up to series production.
The trade PROWERB was founded on in 1979. Today mailings run through the same systems as any other shipment in the house — traceable from the address file to induction.
Sweepstakes launched, prize promised: PROWERB assembles the prize packages and ships them to the winners — over the same lines as every other campaign in Kleve.

Sustainability & Scope 3: Kitting & assembly and logistics with a negative CO2 balance
Agree artwork approvals, address-data processing and the documents required for your project.
The final step determines what the recipient receives. A mixed-up insert is repeated across an entire print run. A mailing needs clean data handling. And Scope 3 reporting makes visible who handles your kitting & assembly.
PROWERB was founded in 1979 as the lettershop of a neighboring print shop — mailing here is not an add-on service but the founding trade. From that grew an operation: 1989 brought fulfillment, 1996 the high-bay warehouse, 2022 the new building with 25,000 square meters — and kitting & assembly and finishing grew out of the lettershop.
Today more than a thousand campaigns run through the lines in Kleve each year — assembled, finished, dispatched. And the in-house team apparel? Runs through the same presses, flocked with the red plus.
The campaign line is planned around the bill of materials, packing effort, available goods and approved data. Changeover and daily output depend on the job; timely sample approval and staffing are prerequisites for ramp-up.
Achievable volume and lead time are agreed for the item mix, goods and data availability, staffing and shift plan.
Sustainability and data protection
PROWERB operates with a negative corporate CO₂ balance. For your Scope 3 calculation, the purchased service must be allocated separately using materials, quantities, transport data, reporting period and your accounting method. The corporate balance is not an automatic negative factor for a shipment. The 2025 sustainability report presents energy data; kWh alone do not calculate customer-specific emissions.
An addressed mailing is data processing on behalf of a controller. Hence: an external data protection officer (Daseco) instead of an internal dual role, plus a whistleblower portal for reports.

Five processes, all in Kleve: flocking, transfer printing, embroidery, screen printing and direct-to-garment printing — up to series production. The in-house team apparel also runs through the same presses.
Kitting & assembly runs by bill of materials, booked in the proprietary enterprise resource system — the ERP and WMS PROWERB CORE with real-time bookings. A mixed-up insert doesn't just go unnoticed once but tens of thousands of times; that's why the final handling step at our facility runs as a managed system process, not a verbal instruction at the packing table.

The campaign line’s changeover guideline is under three hours. Materials, approved packing sample, data and staffing determine the actual date; scope is agreed before launch.
