ERP. The software that gets orders, stock and invoices talking to each other.

An ERP (enterprise resource planning) is business software that links a company's functions on the same database: sales, purchasing, stock, production, accounts, HR. Every piece of information is entered once, and every department sees it.

This entry is part of the AI and automation glossary, where every term has a short definition. Here the definition goes further: which modules an ERP includes, how widespread it is among Italian businesses, what sets it apart from other business software and from a CRM, and when you need one.

What an ERP is

For Eurostat, the European Union's statistical office, the defining feature of ERP is that it's built in modules, “delivered in ‘modules’ that typically integrate processes relevant to planning, purchases, marketing, sales, customer relationship, finance and human resources”. What holds them together is a shared database.

Without an ERP, every department has its own program or spreadsheet, and data moves between them by hand. The order arrives by email, someone retypes it into the warehouse program, someone else copies it onto the invoice. Every step costs time and opens the door to a mistake. With an ERP, the data is created once, at the point where it enters the business.

The modules of an ERP

There are six common modules, and each reads the others' data. No small business switches them all on from day one: you start where the work is most repetitive and add the rest once the first piece works.

Module	What it manages	What happens without retyping
Salesorders and price lists	Quotes, customer orders, price lists, payment terms.	A confirmed order reserves the goods in stock.
Purchasingsuppliers	Orders to suppliers, goods received, matching against supplier invoices.	Goods received update stock levels and wait for the right invoice.
Stocklevels and lots	Quantities available, lots, expiry dates, movements.	Availability is real, with no end-of-day counts.
Productionbills of materials and stages	Recipes or bills of materials, work stages, times, consumption.	The lot produced deducts the raw materials used.
Accountsinvoices and due dates	Sales and purchase invoices, bookkeeping, receipts, payments, financial statements.	The order fulfilled becomes an e-invoice with the right data already in it.
HRhours and costs	Attendance, shifts, hourly cost.	Labour cost feeds into the margin on every job.

Businesses usually start with accounts and sales, where the need is already written into law. Since 1 January 2019, as reported by the Agenzia delle Entrate, the Italian Revenue Agency, invoices between parties resident or established in Italy have been electronic only: so every business invoicing in Italy already has a tool to issue them, and an ERP can be built from there by adding pieces.

How widespread it is among Italian businesses

In 2025, 49.5% of Italian businesses with at least 10 employees used an ERP, according to Eurostat: it's the most widespread business software in the survey, ahead of CRM (21.7%) and business intelligence (16.0%). The EU average is 46.5%. By sector, the lowest share in Europe is in accommodation and food services, at 26.7%.

Business size	Italy	European Union
Small10 to 49 employees	46.0%	41.1%
Medium50 to 249 employees	71.9%	69.9%
Large250 employees or more	85.9%	88.7%
All10 employees or more	49.5%	46.5%

The survey counts businesses that have an ERP to share information between departments. How many modules are actually switched on, and how much data still moves by hand from one department to another, no statistic tells you: you only see it by watching a week's work.

ERP, business software and CRM

In Italy, “gestionale” is the everyday word and ERP the technical one. Business software that only handles invoices, bookkeeping and stock covers some modules; it becomes an ERP when it links sales, purchasing, stock and accounts on the same database. The CRM sits upstream, handling relationships with customers before they turn into orders.

Question	ERP	CRM
Where it looksthe scope	Inside the business: orders, stock, invoices, accounts.	Outward: contacts, enquiries, deals, support.
Where it startsthe first piece of data	With the order.	With the first contact, often weeks before the order.
Who uses itevery day	Admin, warehouse, production.	Sales team, customer support, owner.
What it measuresthe numbers it produces	Margins, stock levels, receipts, delivery times.	Enquiries, response times, deals open and closed.

When you need one, and what to ask

You need an ERP when the same data is typed by hand in two places. The warning sign is retyping: the order that arrived by email and gets retyped into the business software, the delivery note keyed in again on the invoice, the stock level nobody knows for sure. In Barchard and Pace's study, about 1% of data transcribed by hand contains an error, and checking it by eye doesn't reduce that.

Does it connect to what you have? Ask which programs talk to the ERP without retyping: email, the website, the CRM, your accountant.

How do you get out? An ERP is an expensive choice to undo. Ask what format the data exports in, and whether the export includes the history.

Who adapts it to how you work? Modules and workflows have to be configured around the way you work. Ask who does it, how long it takes and what it costs, before you sign.

How Itria works with an ERP

Itria works with the business software you already have, and it's the fourth of the principles set out in Ethics: “We don't throw out the tools you already have”. We build the steps around your business software, where data gets retyped today: PDF documents, orders arriving by email, the numbers the owner wants to read in the morning.

The piece closest to the ERP is automatic document entry: orders, delivery notes and invoices from foreign suppliers read and turned into structured data, with OCR where needed. On a test bench on 4 September 2026, with 30 documents, 234 of 237 extracted fields were correct, 98.7%.
