Grey ERP vs Onyx Pro ERP

Two Oman software options, compared side by side for Oman trades.

Which should you choose?

Grey ERP and Onyx Pro ERP are both Tier A. Compare the typical pricing shown for each below. The tier is not a quality ranking: weigh the pros, cons, pricing and Oman-specific notes below against your trade and region.

Grey ERP

Tier A · Listed

Muscat-based cloud ERP with tendering and a subcontractor portal

Grey ERP is a cloud ERP with a Muscat address in Ghala Heights, linked to the Omani IT company Rawat Al Makan, which also implements Zoho, Odoo and TallyPrime. Its contracting edition lists tendering, contract and project scheduling, automated billing with progress tracking, work orders and a vendor and subcontractor portal. Grey ERP publishes no prices.

Pros

+ Muscat office in Ghala with Omani phone lines
+ Tendering, contract scheduling and progress billing features
+ Vendor and subcontractor portal
+ Wider ERP modules including HR, payroll, fleet and properties

Cons

− No public prices: contact form only
− No Fawtara e-invoicing claims on its site
− No news coverage found: ask for Oman references
− No BIM or critical-path scheduling features listed

Oman note

Grey ERP is run from Muscat (Ghala Heights), so support is local, and its contracting edition covers tendering, progress billing and a subcontractor portal. Its site mentions VAT compliance but not Fawtara e-invoicing, so ask how it will connect to the Oman Tax Authority's system.

Typical Oman pricing: Quote-based; Grey ERP publishes no prices and its 'Pricing' link opens a contact form.

Tier A · Listed

Arabic ERP suite with a Muscat office at Knowledge Oasis

Its Oman company, Ultimate Solutions for Technology LLC, has an office at Knowledge Oasis Muscat, and it lists a dealer in Salalah. Onyx says the system runs in Arabic, English, Turkish, French and German.

Pros

+ Oman office at Knowledge Oasis Muscat, plus a Salalah dealer

+ Wide module range, including HR and payroll

Cons

Oman note

Onyx has an Oman company with an office at Knowledge Oasis Muscat (phone 24170079) and a dealer in Salalah, so local support is available to ask about. Its site does not describe Oman VAT returns or Fawtara e-invoicing, so ask for a demo of both before buying.

Typical Oman pricing: Quote-based; Onyx publishes no prices.
