Integrate my billing

Who this is for

This section is for companies that issue invoices for services provided: utilities, SaaS, telecom, insurance and professional services.

How it works

How QlearBox works for providers

01

Define your services

Configure catalogs, plans, subscriptions, and usage models.

02

Onboard your clients

Clients are created as billing accounts (companies or individuals). Contracts or subscriptions are generated.

03

Register usage or services

Automatically from your systems (API) or manually when needed.

04

Automatic billing calculation

Pending services, periodic or on-demand billing.

05

Issue invoices

Manually, automatically, or triggered externally. Always compliant with local regulations.

06

Collect payments

SEPA, cards, or other methods. QlearBox helps you charge — without holding funds. Full control of late payments and unpaid invoices.

Throughout the entire process, your clients have full visibility through their QlearBox client portal.
