Frequently Asked Questions About Grey ERP in Oman

Common questions about Grey ERP implementation, customization, and support services in Oman

1 - What is Grey ERP and why should businesses in Oman use it?

Grey ERP is a powerful proprietary ERP system built on Microsoft ASP.NET and SQL Server, designed for complete business management?from manufacturing and inventory to accounting, HR, and CRM. Businesses in Oman choose Grey ERP for its affordable licensing with one-time implementation fee plus yearly AMC (saving 60-70% vs commercial ERP), complete customization freedom, modern architecture, and comprehensive modules that handle everything from production planning to financial reporting in a single unified platform.

2 - Is Grey ERP really free? Are there any licensing fees?

Grey ERP is licensed commercial software with a transparent pricing model: one-time implementation fee plus yearly AMC (Annual Maintenance Contract) for server, maintenance, license, and support. Unlike other commercial ERP systems (SAP, Oracle, Microsoft Dynamics) that charge expensive per-user subscription fees, Grey ERP offers an affordable alternative. You pay the implementation fee initially, then an annual AMC that covers everything. This typically saves Omani businesses 60-70% compared to subscription-based ERP total cost of ownership.

3 - What's the difference between Grey ERP and Odoo?

Grey ERP is our own proprietary product built on Microsoft ASP.NET and SQL Server, specifically designed for Omani businesses with built-in compliance for Oman Labour Law, local bank integrations, and Thawani payment gateway. Odoo is a global platform with Community (open-source) and Enterprise (paid) editions. Key advantages of Grey ERP: unlimited customization (we own the source code), Oman-specific features out-of-the-box, on-site support and development in Oman, one-time pricing vs subscription model, and complete control over your ERP system.

4 - Can we self-host Grey ERP or must we use cloud hosting?

Grey ERP offers complete hosting flexibility! You can choose: (1) Cloud Hosting?official managed hosting by Grey ERP creators with automatic updates and 24/7 support, (2) Self-hosted on-premise?install on your own servers for complete control and data privacy, or (3) Managed cloud hosting?we deploy and manage Grey ERP on AWS, DigitalOcean, or your preferred cloud provider with server administration, security hardening, SSL certificates, automated backups, and performance tuning. We help you choose the best option for your business needs and budget.

5 - Does Grey ERP support Arabic language and RTL interface?

Yes, Grey ERP fully supports Arabic language with RTL (right-to-left) interface, making it perfect for businesses in Oman. All modules?including accounting, inventory, manufacturing, HR, and CRM?can operate in Arabic with proper number formatting, date formats, and document printing in Arabic. Our team provides Grey ERP training and support in both Arabic and English to ensure smooth adoption across your organization.

6 - How long does Grey ERP implementation take in Oman?

Grey ERP implementation typically takes 3-8 weeks depending on your business complexity and modules required. A basic implementation (accounting, sales, inventory) can be completed in 3-4 weeks, while comprehensive implementations with manufacturing MRP, custom apps, and integrations typically take 6-8 weeks. Our agile implementation methodology includes business analysis, system configuration, data migration, custom development, user training, testing, and go-live support to ensure rapid deployment with minimal business disruption.

7 - Can Grey ERP integrate with existing software and payment gateways?

Absolutely! Grey ERP offers powerful integration capabilities through REST APIs, webhooks, and connectors. We integrate Grey ERP with payment gateways (Thawani, PayTabs, Stripe, PayPal), shipping providers (Aramex, DHL, FedEx), e-commerce platforms (Shopify, WooCommerce, Magento), banking systems for automated reconciliation, accounting software, warehouse management systems, and custom applications. The Grey ERP Framework makes building custom integrations straightforward using Microsoft ASP.NET and SQL Server.

8 - Can we migrate from Odoo, SAP, or our current ERP to Grey ERP?
