Ordering system

With the ordering system, you can order replenishment from the item list and convert material or subcontractors required from customer orders into an order. Central purchasing, which is controlled by demand requirements, can also be represented.

Controlling, Forecast & Liquidität

Controlling, forecasting & liquidity

You will certainly receive monthly evaluations (“BWA”) from your accounting department or tax advisor — usually around one month after the monthly closing. With work4all, your company's financial situation is available on a daily basis.

Disposition of rental equipment

Will I have a rental item available in sufficient quantity in the future, considering all rental transactions? This question is answered by the work4all scheduling feature—the daily view provides a quick overview of availability.

Inventory management

work4all enables digital warehouse management either via the work4all desktop software or through the Android-based mobile warehouse scanner app for barcodes. The inventory management system can be used for a wide variety of warehouse types.
