Integration

Add invoicing to your SaaS in 3 steps

01

Create entities for each customer

When a customer signs up for your platform, create an entity via the API. Each entity gets isolated data, their own branding, and separate compliance settings.

02

Embed invoicing UI or build with API

Use our white-label web app for a full UI experience, embed React components for specific features, or build entirely custom flows with the REST API and TypeScript SDK.

03

Ship invoicing as a feature

Your customers create invoices, track payments, and stay compliant — all within your product. Charge it as a premium add-on or include it in higher tiers.

Features

Everything SaaS platforms need

White-Label Web App

A full invoicing dashboard your customers can use directly. Dashboard, document management, customer database, settings — all branded as yours.

Multi-Tenant Isolation

Each customer's data is completely isolated. They can never see another customer's invoices, customers, or settings. Manage thousands of tenants from one account.

Recurring Invoices

Let your customers set up subscription billing. Flexible schedules (weekly, monthly, yearly), auto-generation, and optional auto-send.

Webhooks & Events

Get notified when invoices are created, finalized, paid, or overdue. Integrate invoicing events into your existing notification and analytics stack.

Payment Tracking

Full payment lifecycle: mark invoices as paid or partially paid, record payment method and date, automatic overdue detection, and payment reminders.

Custom Branding

Each customer uploads their own logo, sets brand colors, and configures default footer text. Their invoices look like they came from their own system.

Revenue

Invoicing is a revenue multiplier

Invoicing is sticky — once customers issue invoices through your platform, they rarely leave. Add it as a premium feature to increase ARPU, reduce churn, and expand into new markets where compliance is mandatory.

Charge as a monthly add-on ($5-20/mo per customer)
Bundle into premium tiers to drive upgrades
Reduce churn with deeply embedded workflows
Expand into compliance-heavy EU markets
Example: 100 customers using invoicing
Your cost (Space Invoices) ~€247/mo
Your revenue ($10/mo add-on) $1,000/mo
Net margin ~$750/mo

Based on €49 platform + 99 entities × $2 + ~30 docs/entity
