It really comes down to the trade-off between the effort required to make something work for your business and the effort to make your business work for a system. An off-the-shelf system will likely be sufficient for a company that has fairly standard processes, but there will be compromises, such as time to implement. Custom systems provide the best solution for companies with a high volume of legal entities, more complex business workflows, or where system integration is particularly difficult. Whatever solution is chosen, the system must comply with UAE VAT and e-invoicing. It is most beneficial to take a core, tried-and-true system and add on the custom pieces to provide the competitive advantage the business needs.

The quotes vendors give you with respect to an ERP platform are completely disparate. A vendor will provide you with an estimated time to deploy an ERP solution in as little as 90 days. Another vendor suggests only a completely tailored solution can meet the complex requirements for free zone and mainland companies. Additionally, the same vendor said it will take months and possibly over a year for a custom solution to be fully deployed, leaving the deadline for compliance in two years. Ultimately, there is a trade-off between customising and deploying off-the-shelf, but in both cases, risk must be mitigated.

Custom ERP vs Off-the-Shelf ERP

The biggest difference between the two is that off-the-shelf ERP is meant for any company, whereas custom ERP is meant for one specific company. Off-the-shelf ERP is ready to use almost immediately upon purchase and is relatively inexpensive. On the other hand, the biggest downsides are that most of the features will not even be useful to your company, and there is very little that you are able to customise to meet your specific company’s needs.

Custom ERP software can be a bit tricky because of how long the software can take to deploy, but the good thing about custom software is that it can perfectly meet your company’s workflow, whereas off-the-shelf ERP software can take some major tweaks and adjustments to perfectly meet your company’s workflow. The downsides to custom ERP software can be large since it can take up to several months, or even years, to complete. In addition, you have full responsibility and risk for custom software, and you have to own the software roadmap and all future maintenance of the software.

Which ERP Is Best for a UAE Business

For UAE businesses, the best ERP matches process complexity, compliance, and internal resources. First, look at the options below and validate via a demo.

Off-the-shelf software is ideal when:

• Standard processes are at the core of your business (e.g., trading, services, retail, or manufacturing). The standard tools already in the software systems address your core requirements (i.e., billing, purchasing, payroll, VAT, and inventory). 
• You’ve got a quarter to launch. Configuring solutions is done by the user (unlike building), and for that reason, these solutions take weeks to a few months to implement.
•  You’ll want to ensure your software is compliant. Whenever countries (like the UAE and Saudi Arabia) make updates, vendors will make their software updates available for all their customers. 
• Switching vendors is easy with off-the-shelf software, especially with several vendors offering support. In these cases, lifetime cost is easily estimated, and changing vendors is low cost. 

There are cases where a custom software solution is a win.

 Custom software works well if:

There are a lot of unique aspects to your core business, and you would be better served with a unique solution rather than trying to adapt a generic solution to your business. In these cases, a bespoke software solution would provide you a lot more value. This would keep your core business data in one place rather than spreading it across multiple spreadsheets and generic software.

There is a requirement to work across multiple jurisdictions. These companies tend to have more complexity in their business, which would mean generic software would struggle. 

A large proportion of the software needed is custom software for specific customers and includes legacy systems, government websites, and external partner systems. 

It’s unlikely off-the-shelf software can be utilised without extensive customisations, and doing this can result in the risk of building custom software on a platform outside the control of the customer. 

Why a hybrid model works well. It uses a core system that has already been created for you by another software vendor to deal with all your accounting, invoicing, stock control, and regulatory compliance. 

Differences between a Custom ERP and an Off-the-Shelf ERP

A structured selection process can save most ERP deployments from failing and take only about 4–8 weeks to complete. You can create a summary of your work that you can then present to the board.

1. Create your processes. Make a list of all your core workflows. For example, your payroll system, procure-to-pay, WPS, your quotes and your invoicing, and even your inventory systems. Mark those as standard workflows and those as custom ones. By mapping all your processes this way, you can tell all your ERP suppliers which parts of their ERP systems are custom and avoid paying for things you will never use.
2.  Make your must-haves for compliance. Add ZATCA, your corporate tax, and the VAT in the United Arab Emirates. Don’t forget that all your documentation must be available in English and in Arabic. Add ZATCA-compliant invoicing for the PINT AE standard. Add all the location-based rules that you may need for compliance, for example, if you have any offices or locations in Saudi Arabia. 
3. Running an ERP gap analysis includes determining requirements, building validation and exception workflows for invoices, and performing testing. Your requirements against the rules define what you need to customise. This determines the budget you’ll need to allocate.
4. Compare systems and consider both the features that are needed to fulfil your requirements as well as any others you’d like. As a part of this process, think about how well a vendor can provide local support and the systems integration that would be required. In the mix, consider how well off-the-shelf software compares to a more customised or hybrid solution. 
5. Think about how well each vendor’s system will support your workflow in relation to the others. Also, consider the total cost of ownership for a 3-year period and what software fits well into your workflow. Get a vendor to give you a quote for a custom solution, and this will give you an idea of the vendor’s real pricing.
6. Real-world examples of invoices: A good way to find out what software is right for your needs is to ask vendors to do a trial for you using real-world examples of invoices, purchase orders, and a VAT return from your business. Generic trials that don’t include any real-world situations for you don’t cover awkward circumstances like the mess of real-world purchasing, such as partial deliveries and credit notes. The system that does this the best is probably your most trustworthy choice.
7. Start by doing a pilot, and after that, take it one department at a time. It’s better to roll it out in phases, like starting in Finance and Compliance and then moving to Inventory, HR, and finally Projects after all the staff get familiar. Phasing will not only keep everything more controlled but will also fix data issues early on. At each stage of the rollout, you’ll have a clear view of the progress and can stop at any point before spending your full budget. 

Case Study: A Dubai Logistics Firm

For the purpose of this study, we are using an amalgamation of situations.

 For the firm, it used Tally for its accounts and maintained spreadsheets to track jobs.  the firm, e-invoicing was a requirement, in addition to having multiple currencies to make payments and tracking job costs at a container level. After a gap analysis was done, it was clear that an ERP system (like Odoo) could fulfil approximately 80% of their needs. Unfortunately, out-of-the-box ERPs were unable to do job cost tracking.

For this logistics firm, buying a core ERP system to manage finance, VAT, and inventory, plus a single custom module to track job costs, made the most sense. The ERP was ready for business within four months and cost significantly less than a completely bespoke build. The firm also paid the vendor for ongoing e-invoice updates. The main takeaway for firms is to spend the most time and money on customising your differentiators. Buy everything else.

FAQ: Custom ERP vs Off-the-Shelf for GCC Businesses

Q1. Is custom ERP better than off-the-shelf ERP?

Every firm is different, and both have advantages and disadvantages. For custom ERP, firms are able to have their specific processes fully integrated with complete control. For off-the-shelf ERP, firms gain quick access at a lower cost, and system updates are done by the software vendor. When considering both systems, it is best to consider how unique your firm’s workflows are, as well as your IT resources.

Q2. How much does ERP cost in the UAE?

Each ERP project is unique, as costs are driven by system requirements and the firm’s budget. Factors influencing cost are system users, modules, and integration. In the UAE, it can cost AED 20,000 for a small-scope custom ERP project. For larger custom ERP projects, costs can go up to AED 367,000+. Before signing, be sure to account for all costs for three years, including ERP implementation, system hosting, and ERP maintenance and support.

Q3. How long does ERP implementation take in Dubai?

In Dubai, an ERP system using an off-the-shelf system will take only a few weeks to a few months to implement. With a custom ERP system, implementation takes between 6 and 16 weeks, depending on system scope and complexity.

Q4. Does my ERP need to support UAE e-invoicing?

Yes, absolutely. With e-invoicing becoming mandatory for all businesses, an ERP without this capability will leave your business with inefficient compliance processes. Most UAE businesses are required to adopt e-invoicing and are doing so. An ERP should handle the generation, storage, and exchange of all electronic invoices and ensure compliance with FTA requirements. 

Q5. Can I begin with a ready-made ERP and personalise it afterwards?

Yes, and many businesses start that way. However, ensure that any customisations you do are isolated from the main software. If you don’t do this, vendor upgrades will become very expensive, and you’ll lose control of the cost of the system.

Q6. Is there an issue with the location of ERP data within the GCC?

There may be, especially for countries like Saudi Arabia and for industries like healthcare, banking, and government. You should ask your vendors where they host and process data. Be sure to confirm data hosting within the country of your organisation.
