Invoicing API & custom templates

Invoices that are unmistakably yours

One REST API to issue invoices — wrapped in templates you fully control. Set your accent colors or bring your own CSS, then send from your own domain so every invoice looks 100% like your brand, not a billing vendor's.

Why it matters

A branded invoice is a trusted invoice

When an invoice arrives in your customer's colors, from your domain, with no third-party name attached, it reads as legitimate — and legitimate invoices get paid faster. A generic template from an unfamiliar sender does the opposite: it raises questions, triggers spam filters, and slows down payment.

Your colors

Set accent colors to match your brand and JEB applies them across the invoice email and document — headers, buttons, totals, and the pay link.

Your CSS

Need pixel control? Provide your own CSS and lay out the template exactly the way your designers want. No ticket queue, no waiting on a vendor.

Your domain

Invoices are sent from your own domain over your SMTP, aligned with SPF and DKIM, so customers see your name in the inbox — not a third party.

White-label

On Professional and up, every trace of JEB is removed for a 100% white-label experience. Your customers only ever see you.

How it works

Design once, then bill from one API

Customize your template in minutes, then issue invoices programmatically — each one rendered in your brand and delivered from your domain.

1

Customize your template

Pick your accent colors or drop in your own CSS, then watch it render instantly in the live template preview on our docs page — no deploy required.

2

Issue an invoice via the API

A single REST call creates the invoice. JEB renders it in your template and sends it from your domain.

POST /v1/invoices { "customer": "acme", "amount": 4900, "template": "branded" }
3

Get paid

Collect through your own processor, or let JEB collect and pay out to you within 48 hours of payment.

Built for developers

One API, every invoice on brand

Custom templates aren't a separate product — they're part of the same API-first billing platform you already integrate with.

Live template preview

See exactly how your invoice will look before you send a single one, right inside the docs — colors, CSS, and layout in real time.

API-driven

Issue invoices, attach a template, and trigger delivery with a clean REST API. Wire JEB into your product or back office in an afternoon.

Your processor or ours

Keep your own payment processor, or let JEB collect and settle funds to you within 48 hours. Either way, the invoice stays yours.
