easybill Alternative for E-Invoicing API: When easybill and When invoice-api.xhub?

Who is easybill and who is it built for?

easybill is a cloud-based invoicing software from DACH, similarly positioned to Lexware and sevDesk — popular among solopreneurs, freelancers, and small teams. Compared to Lexware and sevDesk, easybill is slightly more focused on invoice management (less full bookkeeping with balance sheet/EÜR), with strong UX for daily work: quotes, invoices, delivery notes, dunning, bank reconciliation.

E-invoicing (XRechnung, ZUGFeRD) is part of easybill — as a feature within the office suite, not as a standalone API service. The user persona is more the office staff member, less the backend developer who wants to embed e-invoicing into their SaaS backend.

invoice-api.xhub.io takes the opposite approach: API-first, focused on the programmatic creation, validation, and delivery of structured e-invoices.

Where easybill shines

If your requirement profile is "I run my daily business through a web UI":

• Fast invoice creation with good UX — even non-technical staff productive immediately
• Dunning with automatic sequences — practical for manual cashflow management
• Bank reconciliation with DACH banks, automatic matching
• DATEV integration for tax-advisor handoff
• Template system for recurring invoices (subscription-like use cases without your own SaaS logic)
• Solid REST API for custom integrations, if you need it for CRM/ERP sync

For solopreneurs and small teams that want everything from one source, easybill is often the more efficient choice. A pure API solution would be overkill.

Where invoice-api.xhub.io is set up differently

invoice-api.xhub is not an office replacement. It's the engine you embed into your own product when that product offers e-invoicing as a feature. Concrete use cases:

1. SaaS with its own billing layer

Your SaaS product has its own subscription logic (Stripe, Lemonsqueezy, Paddle), and customer invoices need to be XRechnung-compliant for German B2B customers. You don't want to import Stripe invoices into easybill and re-export them as XRechnung — you want to generate the XRechnung directly from your billing event, programmatically.

2. E-commerce platform with B2G delivery requirements

You operate a webshop whose customers include public-sector buyers (government agencies). Since the 2025 e-invoicing mandate, you must generate XRechnung with Leitweg-ID. invoice-api.xhub.io turns every order into a valid XRechnung in seconds, ready to send via email or your existing delivery system.

3. ERP module or n8n workflow

You have an existing ERP system or an n8n workflow that produces invoice data. You only need the last step: turn this data into a compliant XRechnung or ZUGFeRD. invoice-api.xhub.io is built for this: one API endpoint, one JSON body, an XML/PDF in return.

4. International e-invoicing workflows

You don't only invoice in Germany: France (Factur-X), Italy (FatturaPA), Netherlands, Belgium, Poland. easybill focuses on DACH; invoice-api.xhub.io covers 14 EU countries with native formats.

5. Standalone validation in CI/CD

You have existing XRechnung generation (e.g., an older ERP module or easybill output) and only want to automate the validation step. invoice-api.xhub.io has a standalone validation endpoint with ~187ms latency.

Concrete pricing comparison

Important: Pricings aren't directly comparable. easybill is an office subscription with invoicing as the main feature. invoice-api.xhub is an API service exclusively for e-invoicing — office tasks (dunning, bank reconciliation) you handle separately.

Migration: can I use both in parallel?

Yes, that's a sensible architecture:

• invoice-api.xhub generates the structured e-invoices from your product backend (e-commerce order, SaaS subscription, ERP workflow)
• easybill handles operational invoice management — there you import the XRechnung outputs for dunning, bank reconciliation, tax-advisor handoff

This split respects single-responsibility: invoice-api handles e-invoicing compliance, easybill handles office workflow.

Decision guide

If you recognize yourself in any of these statements, invoice-api.xhub is the better choice:

• "My invoices are an output of my own product."
• "I don't need an office UI for dunning, I have another system for that."
• "I also invoice in France/Italy/Netherlands and need native formats there."
• "I want to test the e-invoicing workflow in my CI/CD pipeline."
• "Programmatic integration into my product backend is required."

If you recognize yourself here, easybill is the more natural choice:

• "I need a central piece of software for operational invoice management with UI."
• "Dunning, bank reconciliation, and receipt recognition are important."
• "I don't want to build an API integration into my own product."
• "I primarily invoice in DACH, fewer than ~500 invoices/month."

Next step

A 5-minute test in the playground shows faster than any comparison table whether invoice-api.xhub fits your setup:

• Generate a sample XRechnung from a JSON body
• Validate it against the KoSIT schemas
• Convert it to a ZUGFeRD PDF/A-3
• Browse the n8n workflow template

Free tier: 20 invoices/month, no credit card. If you scale beyond that, the Starter plan begins at €23/month (or €18/month with annual billing) and includes 2,000 invoices.
