Software development company in Saudi Arabia

S-Plus is a software development company in Saudi Arabia, with an office in Jeddah and a development team in Cairo. We design and build web systems, SaaS products, ERP and CRM tools, e-commerce platforms and Flutter mobile apps for Saudi and Gulf companies, connect them to payment gateways, ZATCA e-invoicing and the systems you already use, and support them after launch.

Software for companies growing in the Kingdom

Saudi companies are moving more of their work online, and the bar keeps rising: Arabic and English interfaces that both feel native, invoices in the format ZATCA expects, the payment methods customers already use, and reports that management can trust. Off-the-shelf tools cover part of that. The rest, such as your approval chain, your pricing rules, your branches and warehouses and the way your systems talk to each other, is where custom software pays for itself. We start by mapping how the work really runs, then agree with you what to buy, what to connect and what to build.

What our software development team builds for Saudi businesses

• Web systems and portals: customer, supplier and contractor portals, booking and service-request systems, and dashboards with roles and permissions.
• SaaS products: multi-tenant platforms with subscriptions, self sign-up and an admin panel, for companies that want to sell software in the Saudi market.
• ERP, CRM and internal systems: inventory, purchasing, sales, field teams, approvals and reporting across branches, in Arabic and English.
• E-commerce platforms: custom stores, marketplaces and B2B ordering, or a store on our own platform when that is the faster route.
• Mobile apps: Flutter apps for iOS and Android from one codebase, for customers, sales reps, drivers or warehouse teams.
• APIs and integrations: payment gateways such as Tabby, Tamara, MyFatoorah and PayTabs, shipping companies such as SMSA and Aramex, accounting and ERP systems, and APIs for your partners.

ZATCA e-invoicing and other integrations

Saudi e-invoicing (FATOORA) has been rolled out in waves, and businesses brought into the integration phase must connect their invoicing systems to ZATCA's platform. We built ZATCA e-invoicing into our own products, Commera stores and the Sellify pharmacy ERP, so our team already works with the invoice formats, the cryptographic stamp and QR code, and the device onboarding steps. If your current system does not issue compliant invoices, we can add that capability or build the connection to the system you use.

Products we built and run ourselves

The clearest proof of a software company is software it runs every day. S-Plus built Commera, an e-commerce SaaS platform: Arabic and English stores, a drag-and-drop theme builder, more than 70 plugins, Gulf payment gateways and instalments with Tabby and Tamara, shipping with SMSA and Aramex, ZATCA e-invoicing, selling in several markets and currencies, a shared WhatsApp inbox and a mobile app builder. We also built Sellify, an ERP for pharmacies and pharmaceutical wholesalers, with batch and expiry tracking, RSD track and trace, ZATCA e-invoicing, insurance handling, and Flutter apps for sales reps and warehouse teams. The same engineers work on client projects.

How a project runs

1. Discovery and scope. Workshops with the people who will use the system, a map of processes and integrations, and a scope split into a first release and later phases.
2. UI/UX design. Wireframes for every flow, then Arabic (right to left) and English interfaces, reviewed with real users before development.
3. Development in short cycles. Working screens on a staging server every few weeks, so you follow progress instead of waiting for the end.
4. Quality assurance. Functional, regression and device testing in both languages, plus checks on permissions, performance and data imports.
5. Launch, hosting and support. Deployment to cloud servers, backups and monitoring, training for your team, then maintenance and new features. The system can run on our managed hosting or on your own servers.

Technology, code ownership and contracts

We use proven, widely supported technology: Laravel and PHP on the server, modern JavaScript in the browser, Flutter for mobile, MySQL or MariaDB for data, and cloud servers for hosting. Another developer can pick the code up later, and the contract states who owns the code, the data and the accounts. Before you sign, you receive the scope, the milestones, what support includes and how change requests are priced. Roles, permissions and an activity log for sensitive actions are designed in from the start, not added after launch.

A Saudi office and one accountable team

Our Saudi office is on King Abdullah Street in Al-Rowes, Jeddah, where we run workshops and meet clients. Companies in Riyadh, Dammam and the rest of the Kingdom work with the same team, mostly online, with visits when a workshop or launch needs them. Our Cairo team adds development capacity, while one team stays accountable for your project from scope to support. Running in Egypt too? See our software development company in Egypt page.
