BUSINESS APPLICATIONS

From customer
to quote,
order and invoice.

Manage customers, sales and invoicing with modular QUIQQER applications. Build your business platform around the way your company works, then extend it with purchasing, stock management, accounting, a website or a shop.

BUILT AROUND YOUR WORK

Your business has a process.
Your software should reflect it.

Bring customer information, business documents and the applications your team needs into one modular platform.

Keep the customer in view

Customer accounts, numbers, addresses, files, comments and history give your team a place to manage the relationship.

Follow the whole process

The ERP core groups related documents and transactions into processes with chronological histories.

Start with the work you need

Select the applications for your first workflow. Add contracts, purchasing, stock or other business areas as your requirements grow.

THE SALES WORKFLOW

Customer. Quote. Order. Invoice.

Configure the applications for your sales process. The ERP foundation supplies shared process tracking and configurable HTML, PDF, download and email output.

01 · CUSTOMER

Know who you work with

Create and manage customer accounts with addresses, customer numbers and the files and history that belong to them.

02 · QUOTE

Make the offer

Create and deliver customer quotations. Track their status and manage follow-up documents.

03 · SALES ORDER

Define the agreed work

Manage articles, prices, addresses and revisions, with dedicated number ranges and conversion into linked ERP documents.

04 · INVOICE

Invoice and track payment

Prepare, post and deliver invoices. Keep processing and payment status in view and assign incoming payments to eligible documents.

BEYOND THE FIRST INVOICE

Add the next part of your business.

Each area is supplied by its own QUIQQER packages. Choose the scope that fits your project.

Contracts & subscriptions

Manage contract terms, renewals, cancellations and recurring invoices. Add memberships and subscription products for ongoing services.

Payments & accounting

Assign incoming payments, manage dunning, journals and charts of accounts. Export accounting data as configurable CSV or DATEV files.

Purchasing & suppliers

Manage suppliers and purchasing documents, from drafts to posted processes, with articles, statuses, corrections and document delivery.

Stock & availability

Manage product stock across orders and invoices, with availability controls, reversals and low-stock notifications.

Employees & internal work

Manage employee accounts, profiles, addresses, groups, comments and files. Configure access through the platform’s users and permissions.

Electronic invoices

The invoice application generates EN 16931 and ZUGFeRD electronic documents for invoices and credit notes.

WEBSITE, PORTAL & SHOP

Your website is part of the business.

Your customer-facing channels

Build a multilingual website, customer portal or online shop on the same platform as your business applications, with customer accounts, catalogs, checkout and online orders.

BEFORE YOU START

A few practical questions.

Do I need to install the entire ERP?

No. Start with the applications needed for your first workflow and their dependencies. Add further business areas when they become relevant.

What needs to be configured?

Confirm package availability and configure the selected applications for your business, including permissions, number ranges, document templates and payment providers where needed. A catalog entry describes a capability; it does not mean every installation already includes it.

Can I add subscriptions or memberships?

Yes. QUIQQER has packages for memberships, subscription products, customer contracts and recurring payment support. The combination and payment provider must fit the service and billing workflow you want to offer.
