How to automate invoice data entry: a practical guide (2026)

Entering invoices by hand is one of the most time-consuming jobs in accounting. Every invoice means retyping the supplier, amounts, VAT and line items — and a large invoice with dozens of lines can take an hour or more. This article explains how to automate invoice data entry and how much time and money it actually saves.

What is invoice data-entry automation?

Invoice data-entry automation means invoice data reaches your accounting system without manual retyping. Instead of an accountant keying in every field, AI reads the document, recognizes the values and prepares a record that only needs to be reviewed and approved.

How automatic invoice reading works (OCR and AI)

The first step is reading the invoice. OCR turns a PDF or scanned image into text, and AI extracts the structured data from that text. From a typical invoice the system pulls:

• •the supplier name and details (including company and VAT number)
• •the invoice number and dates
• •individual product or service line items
• •net amounts, VAT rates and the total

It matters that the system also handles mixed-VAT invoices, multi-currency invoices and invoices with many lines — exactly where manual entry tends to go wrong.

How to automate invoice entry in 4 steps

• •1. Receive. Invoices arrive in a single mailbox — suppliers send directly, or you forward incoming emails.
• •2. Read and extract. AI automatically reads each invoice and extracts the data and line items.
• •3. Review. The accountant or employee checks the prepared record and assigns dimensions or a project if needed.
• •4. Export to accounting. The approved invoice is exported to your ERP with correct VAT codes and details.

Automation is not just reading — it is classifying the data

Real invoice automation does not stop at reading the data. Ezura also assigns dimensions to invoices automatically — projects, cost centers or responsible people — based on keyword rules you define. That way the accounting record gets not just the right amounts, but correctly classified data, with no manual tagging.

• •Assigning a project or department based on the supplier or line description
• •Recognizing a vehicle's plate number on fuel invoices and assigning it to a vehicle dimension
• •Extracting any other field — contract number, site, responsible person — from the invoice or email

The accountant controls the rules, so the system adapts to your accounting logic rather than the other way around. There is a dedicated article on automatic dimension assignment.

Integrating with accounting systems

Automation only pays off when the data lands in your accounting software with no extra work. Ezura exports invoices to the most popular Lithuanian systems — Rivile, EuroSkaita, Pragma, Agnum and others — with the correct VAT classifiers and dimensions.

How much time and money it saves

Entering one invoice by hand takes 5–15 minutes on average; large invoices take far longer. Once the process is automated, the accountant only reviews, which takes seconds. In practice that means hundreds of invoices can be prepared in minutes instead of hours, and the error rate drops because data is no longer retyped by hand.

Where to start

Getting started is simple — no installation or IT project. You create an account, point invoices at your mailbox, and Ezura immediately starts reading them and preparing them for export. Your first invoices can be tried for free.
