Integration Guide

From first sandbox entity to first proof
in 5 steps

The goal is not a full rollout on day one. The goal is proving one real workflow before you decide how much invoicing surface you want to own.

01

Sign up & create your first entity

Create a free account, then create the business entity you want to test in sandbox. No credit card, no approval process, no time limit.

Free sandbox environment
Entity-first onboarding
No credit card required
Same features as production
02

Generate the right key & integrate

Choose the account key or entity key that matches your architecture, then use our TypeScript SDK, REST API, Embed SDK, or React UI to prove one real workflow.

TypeScript SDK with IntelliSense
REST API with OpenAPI 3.1 spec
Copy-paste React UI components
API Explorer
03

Configure entities & branding

Create entities for each of your customers or sellers. Set their country, currency, tax settings, logo, and compliance modules before live documents exist.

Custom branding per entity
Per-entity tax configuration
Multi-language support (18 locales)
Custom document numbering
04

Go live

Switch from sandbox to live only after you validate the workflow, entity setup, support expectations, and any country-specific compliance steps you need.

Separate sandbox and live keys
Country-specific compliance setup
PDF generation with QR codes
Email delivery
05

Scale

Add more entities as your customer base grows. Each entity is isolated with its own data, settings, and compliance. Usage-based pricing scales with you.

Unlimited entities
Per-entity isolation
Webhooks for automation
Bulk operations & exports
