Software Development Company in Saudi Arabia for Custom Enterprise Software and ERP
Custom enterprise software and ERP implementation for Saudi organisations: bilingual, ZATCA- and PDPL-ready, integrated with the systems you already run.
Key takeaways
- Packaged ERP such as Odoo, SAP or Microsoft Dynamics suits standard processes; custom software suits workflows that differentiate you, and many Saudi enterprises combine both.
- ZATCA e-invoicing Phase 2 has applied in waves since 1 January 2023, and Wave 25 extends integration to businesses above SAR 187,500 in VAT-subject revenue from 1 February 2027.
- Saudi business software must handle 15% VAT, Arabic and Hijri dates, PDPL transfer rules and WPS payroll files through Mudad.
- Amwaj designs the architecture first, then builds in phases with APIs, bilingual dashboards and long-term support.
Amwaj Solutions is a software development company in Saudi Arabia that builds custom enterprise software and implements, customises and integrates ERP systems for Saudi organisations. We deliver bilingual Arabic/English platforms that meet ZATCA e-invoicing, VAT and PDPL requirements, connect to the systems you already run, and are architected to scale over a five-year horizon.
Most organisations that approach a software company in Saudi Arabia are not short of software. They are short of software that fits: an ERP that handles finance but not the way operations actually run, spreadsheets filling the gaps, and e-invoicing deadlines that expose every disconnected system. Our job is to decide what to buy, what to build and how to connect it, then deliver it to production standard.
Custom enterprise software or off-the-shelf ERP: which fits your business?
There is no universal answer. Packaged ERP platforms such as Odoo, SAP, Microsoft Dynamics 365 and Oracle encode decades of accounting and supply-chain practice. Custom enterprise software encodes your process. The right choice depends on how standard your operations are and where your competitive advantage sits.
| Factor | Off-the-shelf ERP (Odoo, SAP, Dynamics, Oracle) | Custom enterprise software | Hybrid: ERP core + custom layer |
|---|---|---|---|
| Best for | Standard finance, procurement, inventory and HR | Unique operational workflows, customer platforms, SaaS products | Standard back office plus distinctive operations |
| Time to first value | Faster for core modules | Slower; delivered in phases | Core live first, custom modules added in phases |
| Fit to your workflows | You adapt to the product, or pay to customise it | Built around your workflows | Back office standardised, operations tailored |
| Ownership and licensing | Recurring per-user or subscription licences | You own the code; no per-user licence | ERP licences plus custom code you own |
| Saudi requirements (ZATCA, VAT, Arabic) | Depends on edition, version and local partner add-ons | Designed in from the start | ERP handles accounting; custom layer handles the rest |
| Upgrade risk | Heavy customisation can break upgrades | Controlled by your own roadmap | Low if customisation stays outside the ERP core |
When off-the-shelf ERP is the right call
If your finance, purchasing, inventory and payroll follow common patterns, an established ERP is usually the lowest-risk route. Our role is ERP implementation done properly: configuration, checks on Saudi localisation, data migration, integration and training, without unnecessary code. Our guide to choosing an ERP system in Saudi Arabia compares the main options in more detail.
When custom software development is the right call
Custom software development makes sense when the process itself is the differentiator: a field-operations platform, a regulated approval workflow, a B2B portal or a SaaS product you will sell to other GCC businesses. It also makes sense when per-user licence costs grow faster than the value the platform delivers.
Why many Saudi enterprises end up hybrid
In practice, many organisations keep a standard ERP as the system of record for accounting and build custom enterprise software around it for the operations it does not fit. Keeping customisation outside the ERP core protects your upgrade path.
How do we customise and integrate your existing ERP?
Replacing an ERP is expensive and disruptive, so we start by asking whether the one you have can be extended. Typical work includes:
- Customisation: workflows, approval chains, Arabic print templates, reports and role-based screens.
- Integration: connecting the ERP to e-commerce, point-of-sale, banking, CRM, HR and warehouse systems through documented APIs.
- Data migration: cleansing and moving master data, open balances and history from legacy systems, with reconciliation at every step.
- Automation: removing manual re-keying between systems. For a Saudi industrial group, RPA with AI decision layers across operational ERP systems cut processing time by 72%. See the industrial automation case study.
What Saudi requirements must your ERP and business software meet?
Every system we deliver is checked against the regulations that apply in the Kingdom. These are the ones that most often shape ERP and enterprise software projects.
ZATCA e-invoicing (Fatoora) Phase 2
The Zakat, Tax and Customs Authority (ZATCA) introduced e-invoicing Phase 1 (Generation) on 4 December 2021 and Phase 2 (Integration) from 1 January 2023, rolled out to taxpayers in waves. In the integration phase, standard tax invoices must be cleared by ZATCA in real time and simplified invoices reported within 24 hours, as UBL 2.1 XML with a cryptographic stamp and QR code. Wave 25 covers businesses whose VAT-subject revenue exceeded SAR 187,500 in any year from 2022 to 2025, with integration with Fatoora from 1 February 2027 (ZATCA announcement). We build this into ERP, billing and POS systems through our ZATCA e-invoicing integration service.
VAT at 15%
Saudi VAT has been 15% since 1 July 2020. Your system needs correct tax categories, credit and debit notes linked to the original invoice, and reports that reconcile with your VAT return.
Arabic, bilingual interfaces and Hijri dates
We design for Arabic and English from day one: right-to-left layouts, correct Arabic search and sorting, bilingual documents, and Hijri (Umm al-Qura) dates alongside Gregorian wherever contracts, HR records or government submissions need them.
PDPL and data residency
The Personal Data Protection Law (PDPL), regulated by the Saudi Data and AI Authority (SDAIA), came into force on 14 September 2023 and became enforceable on 14 September 2024 (SDAIA national data governance platform). It does not ban hosting outside the Kingdom outright, but transferring personal data abroad must meet SDAIA's transfer conditions. For government and critical-infrastructure entities, data localisation requirements are set through SDAIA's National Data Management Office (NDMO). We default to hosting in Saudi cloud regions or on-premise, with role-based access and audit logging, aligned with our cybersecurity and compliance service.
Mudad and WPS payroll
Private-sector employers pay salaries under the Wage Protection System (WPS) overseen by the Ministry of Human Resources and Social Development, uploading monthly payroll data through the Mudad platform. Payroll modules we build or integrate produce WPS-ready wage files and keep employee records consistent with what is submitted.
APIs, integration and dashboards
Enterprise software only pays back when data moves between systems without manual re-entry. We design REST APIs and integration layers with versioning, authentication and monitoring, so ERP, CRM, HR, banking and government platforms exchange data reliably. On top of that data we build bilingual dashboards and business intelligence: live KPIs for finance, operations and management, drill-down to the transaction, and role-based access so each team sees what it should.
The same engineering applies to SaaS development: multi-tenant architecture, subscription billing, ZATCA-compliant invoicing and Arabic-first onboarding for products sold across the GCC.
How does our software development process work?
We architect first, because most failed enterprise projects fail on decisions made in their first few weeks. Read more on building scalable enterprise software in Saudi Arabia.
- Discovery: map processes, users, data, integrations and regulatory scope; decide buy, build or hybrid.
- Architecture: data model, integration design, hosting, security controls and a phased roadmap, reviewed with your team before development starts.
- Phased build: working releases every few weeks, demonstrated in Arabic and English, so you see progress rather than status reports.
- Testing and compliance: functional, performance and security testing, plus validation against ZATCA's e-invoicing technical requirements where e-invoicing is in scope.
- Migration and launch: data migration with reconciliation, user training and a controlled go-live.
- Support and evolution: monitoring, fixes, updates when regulations change and a roadmap for new features.
What support do you get after go-live?
Enterprise software is never finished. Regulations change (ZATCA has so far announced 25 e-invoicing integration waves), and your business changes with them. We provide ongoing maintenance, performance monitoring, security updates and change requests under an agreed support model, with full documentation so your own team is never locked out of its system.
Why work with Amwaj Solutions?
Among software companies in Saudi Arabia, we focus on the enterprise end: bilingual platforms, regulated data and systems that must integrate cleanly. Security is embedded and NCA-aligned from the start, and every system is built to production standard with a five-year scalability horizon.

ERP & Custom Enterprise Software
Frequently Asked Questions
How much does custom software or ERP implementation cost in Saudi Arabia?
Cost depends on scope rather than a fixed rate: the number of modules and users, how far your processes depart from standard ERP, integrations, data migration volume, ZATCA e-invoicing requirements, hosting and ongoing support. Packaged ERP adds recurring licence costs, while custom software shifts spend towards development and ownership. After a discovery call, a reliable partner should give you a phased proposal with clear milestones.
Is Odoo, SAP or Microsoft Dynamics better than custom software?
Packaged ERP is usually better for standard finance, procurement, inventory and HR, because those processes are well understood and the platforms are mature. Custom software is better where your operational workflow is the differentiator or licence costs scale badly with users. Many Saudi organisations combine both: a standard ERP as the accounting system of record, with custom modules and integrations around it.
Does my ERP need to integrate with ZATCA for Phase 2 e-invoicing?
If you are a VAT-registered business selected in one of ZATCA's integration waves, your invoicing system must connect to the Fatoora platform, clearing standard tax invoices in real time and reporting simplified invoices within 24 hours. Wave 25 covers businesses whose VAT-subject revenue exceeded SAR 187,500 in any year from 2022 to 2025, with integration from 1 February 2027.
Can you customise our existing ERP instead of replacing it?
Yes. We first assess whether your current ERP can meet the requirement through configuration, extensions or an external custom layer connected by APIs. Replacement is only recommended when the platform cannot support Arabic, ZATCA integration, your transaction volumes or your roadmap. Keeping custom code outside the ERP core protects future upgrades and reduces long-term maintenance effort.
Do you build SaaS products for the Saudi and GCC markets?
Yes. We engineer SaaS platforms from system design to production: multi-tenant architecture, subscription and billing logic, ZATCA-compliant invoicing, bilingual Arabic/English interfaces, APIs for customer integrations, and hosting that can keep data inside Saudi Arabia. Architecture is planned for growth from the start, so the platform can scale without a rewrite.
Where will our ERP and business data be hosted?
We recommend hosting in Saudi cloud regions or on-premise by default. The PDPL allows personal data to be transferred abroad only under SDAIA's conditions, and government and critical-infrastructure entities follow localisation requirements set through SDAIA's National Data Management Office. We design hosting, access control and logging around your data classification before development starts.
How long does an ERP implementation take?
Timelines depend on the modules, data quality, integrations and how many sites go live. A phased approach is usually safest: core finance and e-invoicing first, then operational modules and dashboards. We agree a realistic plan after discovery, with milestones you can track, rather than quoting a timeline before we understand your processes and data.
