Customers and contacts
weclapp supports management of contacts, prospects, customers, sales opportunities, offers and all activities related to business partners. Each customer contact can be easily set up and archived in the CRM system: whether it’s a phone call, email, site visit, etc. All system users can get organized via the DMS and via the meeting, address and task management functions.
Offers and orders
Professional offers with just a few clicks! Save time with offer templates for similar offers. Once adapted, all documents are created in your corporate design. Everything under your control: Freely design logos, standard texts and backgrounds. If you select the items and recipients, shipping costs, payment terms and targets are automatically applied.
Project management simplifies the areas of task management, teamwork and document management. Project-related tasks can be created and quickly classified into the right project structure via the drag and drop function. Manage milestones, distribute quotas and monitor progress at all times.
Time and activity recording
Project team members can record their hours directly to a project or to the corresponding task thanks to live time logging. Since weclapp is web-based and is also available as an app, times can also be stopped and recorded on the go or with a customer. Finally, all recorded times and services can be transferred into a service record or an invoice with one mouse click.
Invoicing and accounting
Create legal and professional invoices with one click! Complete your monthly statements by exporting invoices, receipts and payment flows in a DATEV-compliant manner and send them to your tax advisor. The interface to the company’s online banking saves time on transfers and incoming payments.
Optional: Helpdesk
Accelerate and optimize your customer service with the optional Helpdesk add-on. It instantly bundles all channels: Whether via customer portal, email or phone, all (internal and external) requests are neatly listed in the ticket system. Features such as email-to-ticket and the self-service portal help you and your team deliver excellent service to your customers.
