The modules in overview

Order processing

Automate your order processing! weclapp supports the entire workflow: from processing requests to creating an offer, processing orders to production—even compiling orders, creating delivery slips, shipping and finally invoicing.

You can map different types of business processes, such as advance orders from the warehouse, service orders, project orders, drop shipments or cash sales. Settlement of orders may be processed as a cash invoice, credit note, installment payment or advance payment invoice.

Disposition and purchasing

The purchasing functions facilitate procurement automation (disposition), ensuring delivery dates, simplifying the procurement process and reducing the processing effort, all while increasing transparency.

The online ERP system uses demand or consumption-based disposition to create order and production offers. Vendor selection for the purchase orders is made by activating and prioritizing sources of supply in the item list.

Warehouse management

Warehousing is responsible for storing and managing inventory in terms of value and quantities, as well as all material movements. Warehouse management can be organized for any number of warehouses and storage areas. Inventory management can be illustrated in summary or in detail.

Advantages for you: Overview of inventory levels, tracking and transparency of material movements, availability of information on short-term income statements as well as reduction of processing expenditures.

Product and item management

You can enter detailed item and price information, surcharges and discounts at different levels: individual customer discounts and graduated pricing, prices according to distribution channels and for individual product groups, promotional prices and much more.

Quantity conversions saved to the item can be selected in the corresponding workflows. For example, when creating offers, the correct sales price is automatically calculated by weclapp.

Return management

And the system handles returns easily and efficiently. The Cloud ERP software supports the entire process: from preparing returns, through arranging credit notes or compensation delivery, to determining the cause of the problem. This saves you time, prevents errors and collects valuable information for improving your products and business processes.

 weclappPOS point-of-sale-software

You can also use our fully integrated point-of-sale software, weclappPOS, from just €19 per month per user. It’s clear and easy to use. The software doesn’t require installation and is ready for use on all web-enabled devices (PC, laptop, tablet, smartphone). Use of the cloud simplifies data administration: Thanks to automatic synchronization, all information about items, warehouses, inventory, etc. is always up-to-date.

Interfaces for important expansions

Connecting to shop and marketplace

weclapp merchandise management offers bi-directional interfaces to popular online shopping systems (Shopware, Magento, WooCommerce, etc.) and popular marketplaces (e.g. Amazon, eBay, Rakuten, etc.). These interfaces enable automatic synchronization of offers, items, orders, invoices, deliveries and much more between the shop, marketplace and merchandise management system.

weclapp für E-Commerce-Unternehmen

Connecting to shipping provider

The software can generate packing slips and shipping labels via interfaces to shipping service providers. This allows you to create and bill shipment labels from a single source and, at the same time, keep your data up-to-date in the merchandise management system. In this way, Cloud ERP system customers in the e-commerce sector can automate this process almost 100% via a full data synchronization.
