Incoming goods


Order management


The order management encompasses all activities required to fully process customer orders. The software supports the entire workflow associated with order processing, starting with the preceding customer request and corresponding proposal. Specifically, this means proposal development, order development/ compilation, shipping, and invoicing.
Sales modules allow you to display various types of business processes such as standard orders (warehouse sales), standard orders with purchase order, services contracts, project orders, drop shipments, direct sales to the customer or cash sales. Order invoices can be processed as a cash sale, credit sale, partial payment or pre-payment.

Planning and Purchasing


The procurement functions enable you to automate some of your purchasing activities, confirm and oversee delivery times, simplify procurement processes and reduce transaction procedures for purchasing while simultaneously increase transparency.
With on-demand or consumption based planning and procurement, the ERP system develops ordering and production recommendations. Supplier selection is handled by means of the activation and prioritization of supply sources in the master list. As needed, goods receipt slip can be created after the goods have arrived.

Warehouse management


The warehousing function of the online ERP system focuses on storage and management of inventory levels, quantitative and value-based and all movements of material. The warehousing function works with any number of warehouses (main warehouse, external warehouse, high bay storage, etc.) or other storage facilities. Inventory levels can be displayed summarily (for a particular item) or in detail.
Advantages for you: Overview of inventory levels, tracking and transparency of material movements, availability of information for quick profit and loss accounting, reduction in processing costs.

Product- and item management

stock preview

The item overview presents your products in a clear and structured manner. Detailed item and price information can be filed under each item. The professional product and item management feature makes it possible to add surcharges or provide discounts on various levels. Thereby, individual customer prices, graduated pricing scales, pricing according to sales channel and prices for individual product groups or particular campaigns can be designated.

Merchandise management interface – mail order

weclapp’s merchandise management system provides bi-directional interfaces to popular online shop systems (Magento, Shopware, Amazon, Ebay, etc.) which allow you to keep your proposals, items, orders, invoices, deliveries and much more synched between weclapp and your implemented shop system. Delivery slips are generated the same way as picking/packing lists by the ERP system.

With interfaces to shipping services providers the Cloud ERP software can generate packaging/shipping labels. This allows for shipment labeling and billing from one source and, at the same time, keeps all your data in the merchandise management system up to date. The Cloud ERP System allows customers in the mail order business to virtually automate the process through a full synchronization of information.
