More than 3,000 companies rely on ZEP

Transparent profitability with ZEP

With ZEP, you can enter prices & receipts centrally and completely without paperwork.

Automatic document entry

Collect documents centrally and process them in a structured manner

Incoming documents first end up in the receipt box and are processed further from there. Admins assign each document to a project and, optionally, to an employee before a complete document with document number is created. Controllers receive read rights to the mailbox and thus keep track of things without interfering with the recording.

Project-based pricing

Individual prices per project and activity

Set project and activity-related prices and define specific hourly rate models for each project. Automatic currency conversion and individual tax rates per document ensure that your billing processes run smoothly even with complex project structures.

Further billing & conversion

Project-specific further invoicing of documents

Define individually which external costs are passed on to the customer. Documents can be entered in various currencies and are automatically converted into the customer currency so that international projects are correctly billed without additional manual effort.

Supplier management

Create suppliers centrally and clearly allocate costs

Manage suppliers, including contact information and payment details, centrally in ZEP. When entering documents, employees assign external costs directly to the respective supplier, which enables clean evaluations and clear controlling without rework.
