Features and specs

What each product offers, as listed by its team.

NormAPI 5 features
eInvoiceTool 0 features
  • API-first developer approach
    NormAPI is built for developers, so its services can be integrated into applications through REST-style endpoints instead of manual workflows. This usually means faster integration and easier automation. I could not verify the details of the current product, so check the live site for the exact feature set.
  • Reduces in-house development effort
    Using a hosted API lets teams avoid building and maintaining this functionality themselves. That saves engineering time and ongoing maintenance, especially for small teams and startups.
  • Scalable, usage-based model
    Hosted API services like this typically let you start small and scale with demand, so you don't have to manage infrastructure. Confirm the actual pricing tiers and rate limits on the official pricing page.
  • Language-agnostic integration
    Because it is exposed over HTTP, it can be called from almost any language or platform, such as Python, JavaScript, Ruby, or PHP. This makes it flexible across different tech stacks.
  • Quick start for prototyping
    A hosted API usually requires only an account and an API key, so teams can test and prototype quickly before committing to a larger integration.

Questions & Answers

As answered by people managing NormAPI and eInvoiceTool.

What makes your product unique?

eInvoiceTool's answer:

It covers the main European e-invoice formats in one free tool: Polish KSeF, German XRechnung, ZUGFeRD / Factur-X and Peppol UBL. You can both read an invoice as a normal document and validate it against the official rules. Everything runs in the browser, so invoice files never leave your computer.

How would you describe the primary audience of your product?

eInvoiceTool's answer:

Small businesses, freelancers, accountants and bookkeepers in Germany, Poland and other EU countries who receive e-invoices as XML or PDF files and need to read or check them. It is also useful for developers testing invoice exports against XRechnung, Peppol or KSeF rules.

Why should a person choose your product over its competitors?

eInvoiceTool's answer:

Most viewers or validators handle a single format, require an account, or upload your invoice to their server. eInvoiceTool is free with no signup and no limits, works with KSeF, XRechnung, ZUGFeRD and Peppol, and keeps files private because nothing is uploaded. Error messages show the official rule ID with a plain explanation, and the interface is available in English, German and Polish.

Which are the primary technologies used for building your product?

eInvoiceTool's answer:

WordPress for the website, with a custom plugin written in plain JavaScript. Invoices are parsed and validated fully client-side in the browser; the validation rules are based on the official EN 16931, XRechnung, Peppol BIS and KSeF specifications.
