ERP implementation is one of the biggest change projects a company undertakes. Done well, it gives you one version of the truth, faster closing and better decisions. Done badly, it disrupts operations for months. This guide outlines a proven approach for Saudi businesses.
Phase 1: Preparation
- Appoint an executive sponsor and a full-time or near-full-time internal project manager.
- Nominate key users from each department who will design, test and train.
- Agree scope: modules, companies, branches and integrations for phase one.
- Set success measures, such as days to close the month or inventory accuracy.
Phase 2: Discovery and design
Workshops map current processes and agree future processes in the new system. Key outputs include the chart of accounts, cost centres, item and customer master structures, approval workflows, user roles and report list. Document every decision; it becomes the reference for configuration and testing.
Phase 3: Build
The partner configures the system, develops necessary customisations and builds integrations. In Saudi Arabia this almost always includes VAT setup and ZATCA e-invoicing integration. See our ZATCA guide.
Phase 4: Data migration
Plan which data moves: opening balances, open invoices, customers, suppliers, items, stock and fixed assets. Clean data before migration and run at least two trial migrations. Our ERP data migration checklist covers the details.
Phase 5: Testing
- Unit tests by the partner on each configuration.
- Integration tests for data flowing between systems.
- User acceptance testing by your key users with real scenarios, such as a full order-to-cash and procure-to-pay cycle.
Do not go live until key users sign off.
Phase 6: Training
Train key users first, then have them help train their colleagues. Provide short guides in Arabic and English for common tasks.
Phase 7: Go-live
Choose a quiet period, often a month or quarter start. Freeze changes in the old system, run final migration, verify balances and switch. Arrange on-site or rapid remote support for the first weeks.
Phase 8: Stabilisation
The first month-end close in the new system is the real test. Keep the partner close, track issues daily and prioritise fixes.
Common pitfalls
- Customising the ERP to copy old processes exactly.
- Key users who are too busy with daily work to participate.
- Dirty data migrated without cleaning.
- Underestimating training.
- Adding scope halfway through.
How long does it take?
Duration depends on scope, number of entities, data quality and customisation. A single-company implementation of core modules is far shorter than a multi-entity rollout with manufacturing and heavy integration.
