How to Send E-Invoices Without Changing Your Current System

The Problem with "Rip and Replace" Solutions

Many traditional e-invoicing providers expect you to adopt their entire platform—new invoice templates, new workflows, new training for your team. This approach is expensive, disruptive, and often unnecessary.

Your current invoicing system works for your business. You've customized it, your team knows it, and it integrates with your other tools. Why throw that away?

"The best e-invoicing solution is one you barely notice—it should enhance your existing workflow, not replace it."

Three Ways to Connect to Peppol

Modern Peppol access points offer multiple integration methods, so you can choose the approach that fits your business. Here's how Invoro supports different workflows:

Most businesses start with web forms or email, then graduate to API as their volume grows. Choose what makes sense today—you can always upgrade later. See our pricing tiers for volume details.

Real-World Integration Scenarios

Let's look at how different types of businesses can stay compliant without disruption:

How Email + AI Processing Works

The email forwarding method is particularly popular because it requires zero technical knowledge. Here's what happens behind the scenes:

The AI handles multiple formats (PDF, Word, Excel, even scanned images) and learns from corrections, getting more accurate over time. If anything looks unclear, you'll get a quick email asking for confirmation before sending.

API Integration for Developers

For businesses with technical resources or high invoice volumes, direct API integration offers maximum control and automation. Here's what the integration looks like:

POST https://api.invoro.com/v1/invoices
Content-Type: application/json
Authorization: Bearer YOUR_API_KEY

{
  "recipient": {
    "name": "ACME GmbH",
    "peppol_id": "9930:DE123456789",
    "address": {...}
  },
  "invoice": {
    "number": "INV-2025-001",
    "date": "2025-01-15",
    "due_date": "2025-02-14",
    "currency": "EUR",
    "line_items": [...],
    "total": 1250.00
  }
}

What About Receiving Invoices?

Compliance isn't just about sending—you also need to be able to receive e-invoices from your suppliers. Here's how Invoro handles incoming invoices:

Keeping Your Accounting Software

One concern we hear often: "Will this work with my accounting software?" The answer is almost always yes, because Invoro sits alongside your existing tools rather than replacing them.

Migration Timeline: What to Expect

Worried about how long this takes to set up? Here's a realistic timeline based on integration method:

Real Benefits Beyond Compliance

While the primary reason to adopt e-invoicing is compliance, many businesses discover unexpected benefits:

• 💰 Faster payments: Electronic invoices are processed quicker—many businesses see DSO (days sales outstanding) drop by 20-30%
• 🎯 Fewer errors: Structured data reduces manual data entry mistakes
• 📈 Better tracking: Real-time delivery confirmations mean you always know invoice status
• 🌍 EU-wide invoicing: Once you're on Peppol, invoicing to any EU country works the same way
• 📊 Improved reporting: Structured invoice data makes financial analysis easier

The Bottom Line

E-invoicing compliance doesn't mean starting over. The right solution adapts to your workflow, not the other way around.

Whether you're a solo consultant forwarding a few invoices per month or an enterprise processing thousands, there's an integration path that fits. Start simple, scale when needed, and keep using the tools that already work for your business.

That's how modern e-invoicing should work—invisible until you need it, flexible when you do.
