ERP: definition, how it works and how to choose one for a Swiss SME

Q: What is the difference between an ERP and simple accounting software?

Accounting software manages only accounting entries and taxation (VAT, balance sheets, ledgers). An ERP is broader: it integrates accounting, but also customer invoicing, supplier purchasing, inventory management, human resources, payroll, CRM, and sometimes production or project management. The key value of an ERP is integration: an invoice issued in the sales module automatically generates the accounting entry, updates inventory and notifies treasury.

Q: Is an ERP suitable for small businesses (micro-enterprises/SMEs)?

Yes. Modern cloud ERPs (SaaS) are designed to be accessible to SMEs, and even to micro-enterprises from just a few employees. They have affordable pricing (monthly subscription), do not require an internal server and can be deployed in a matter of weeks. For a Swiss SME, an ERP adapted to local regulations (Swiss VAT, QR-bill, Swissdec, veb.ch chart of accounts) is particularly effective.

Q: Cloud ERP or on-premise ERP: which choice for a Swiss SME?

An on-premise ERP is installed on the company's own servers — it offers full control but requires IT infrastructure, manual updates and a high initial cost. A cloud ERP (SaaS) is hosted by the vendor — the business accesses it via a browser, with no installation or maintenance. For a Swiss SME, the cloud offers rapid start-up, automatic updates and a predictable cost. The question of data location (hosting in Switzerland) is important for nFADP compliance.

Definition

An ERP (Enterprise Resource Planning) is an information system that centralises all of a company's data and management processes in a single shared database. The objective is to eliminate silos between departments (sales, accounting, inventory, HR) and to provide a real-time view of the company's activity.

The term "ERP" was popularised by Gartner in the 1990s, in reference to MRP (Manufacturing Resource Planning) systems used in industry. Today, ERPs cover all sectors, including services.

Typical modules

A modern ERP for SMEs generally includes the following modules:

Module	Functions covered
Accounting	General ledger, journals, balance sheet, profit and loss account, VAT
Invoicing	Quotes, orders, customer invoices, QR-bills, collections
Procurement	Supplier orders, goods receipt, supplier invoices
Inventory	Stock management, movements, valuation
CRM	Contacts, opportunities, customer follow-up, sales pipeline
HR and payroll	Employee records, contracts, payslips, salary certificates
Treasury	Bank statements, reconciliation, cash flow forecasting
Projects	Time tracking, planning, project billing

Integration between modules is the fundamental value: a sale created in the CRM automatically generates the invoice in the invoicing module, which triggers the accounting entry, updates the cash flow forecast and decrements inventory.

Cloud ERP vs on-premise

Criterion	Cloud (SaaS)	On-premise
Deployment	Immediate, via browser	Installation on internal server
Maintenance	Managed by the vendor	Company's or IT team's responsibility
Cost	Predictable monthly subscription	High initial licence + maintenance
Updates	Automatic	Manual, scheduled
Accessibility	Anywhere, any device	Internal network or VPN
Data	With the vendor (country of choice)	Within the company

For Swiss SMEs, cloud ERPs with hosting in Switzerland offer the best balance between simplicity, nFADP compliance and cost.

Swiss context

Swiss SMEs have specific ERP requirements that generic international solutions sometimes meet poorly:

Swiss VAT (3 rates, FTA return, effective and NDFR methods)
QR-bill (SIX Group standard, QR-IBAN)
Swiss payroll (OASI, LPP, LAA, source tax, Swissdec ELM)
veb.ch chart of accounts (Sterchi)
nFADP compliance (Swiss hosting, data protection)
Language: French, German, Italian depending on the region

A localised ERP for Switzerland avoids costly customisations and the risk of non-compliance.

How Neoffice is positioned

Neoffice is a cloud ERP designed specifically for Swiss SMEs. It natively integrates the QR-bill, the three Swiss VAT rates, Swissdec-compliant payroll, the veb.ch chart of accounts and CAMT bank statements — with no additional configuration. Data is hosted in Switzerland, in line with nFADP requirements.
