BUSINESS APPLICATIONS
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
Bring customer information, business documents and the applications your team needs into one modular platform.
Customer accounts, numbers, addresses, files, comments and history give your team a place to manage the relationship.
The ERP core groups related documents and transactions into processes with chronological histories.
Select the applications for your first workflow. Add contracts, purchasing, stock or other business areas as your requirements grow.
THE SALES WORKFLOW
Configure the applications for your sales process. The ERP foundation supplies shared process tracking and configurable HTML, PDF, download and email output.
01 · CUSTOMER
Create and manage customer accounts with addresses, customer numbers and the files and history that belong to them.
02 · QUOTE
Create and deliver customer quotations. Track their status and manage follow-up documents.
03 · SALES ORDER
Manage articles, prices, addresses and revisions, with dedicated number ranges and conversion into linked ERP documents.
04 · INVOICE
Prepare, post and deliver invoices. Keep processing and payment status in view and assign incoming payments to eligible documents.
BEYOND THE FIRST INVOICE
Each area is supplied by its own QUIQQER packages. Choose the scope that fits your project.
Manage contract terms, renewals, cancellations and recurring invoices. Add memberships and subscription products for ongoing services.
Assign incoming payments, manage dunning, journals and charts of accounts. Export accounting data as configurable CSV or DATEV files.
Manage suppliers and purchasing documents, from drafts to posted processes, with articles, statuses, corrections and document delivery.
Manage product stock across orders and invoices, with availability controls, reversals and low-stock notifications.
Manage employee accounts, profiles, addresses, groups, comments and files. Configure access through the platform’s users and permissions.
The invoice application generates EN 16931 and ZUGFeRD electronic documents for invoices and credit notes.
WEBSITE, PORTAL & SHOP
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.
The order application can create invoices from orders, manually or automatically according to order and payment state. Your selected packages and configuration determine how the steps connect.
GET STARTED WITH QUIQQER
Install the platform, add the applications for one business process and configure them for your team.
01 · INSTALL
Choose AI-guided setup, Docker or the PHAR installer. The installation guide explains the available paths and how to get your own system running.
02 · ADD APPLICATIONS
For a customer-to-invoice workflow, identify the customer, offer, sales-order, invoice and ERP packages. Check their availability and install the applications and dependencies your project needs.
03 · CONFIGURE & USE
Sign in to the administration and open the applications you installed. Configure permissions, document numbering and templates, then start with a test customer and draft documents for your selected workflow.
BEFORE YOU START
No. Start with the applications needed for your first workflow and their dependencies. Add further business areas when they become relevant.
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.
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.
