7 Questions to Ask ERP Vendors Before Signing a Contract in Singapore

You have sat through three demos. The sales rep has shown you dashboards that look beautiful. The ROI spreadsheet says you will break even in 18 months. Your COO is already picturing a world without manual data entry. But here is the uncomfortable truth: most ERP projects in Singapore fail not because of the software, but because of what was left unasked during the sales process. The contract you sign today will shape your operations for the next decade. So before you put pen to paper, you need a structured way to compare vendors. These seven questions will give you that framework.

Why Most ERP Selection Processes Miss the Mark

Many business leaders treat ERP selection like buying a car. They compare horsepower (features), look at the colour (UI), and take a test drive (demo). But an ERP system is not a car. It is more like renovating a HDB flat while you are still living in it. The disruption touches every department. The costs go beyond the sticker price. And the contractor (your vendor) will be in your life for years.

The problem is that most ERP vendor selection questions Singapore decision-makers ask are too surface level. They ask about modules and pricing. They forget to ask about what happens when things go wrong. They skip the hard conversations about data ownership, termination clauses, and local regulatory compliance.

Let us fix that. Here are the seven questions that will separate a good vendor from a dangerous one.

1. How Do You Handle Singapore-Specific Compliance and Reporting?

This is the single most important question for any Singapore business. Your ERP must handle IRAS tax requirements, GST filing, and the upcoming e-invoicing mandate (InvoiceNow). It must also comply with the Personal Data Protection Act (PDPA).

Ask the vendor directly:

• Does your system support the latest IRAS e-invoicing framework?
• Can it generate the reports needed for ACRA filing?
• How does it handle multi-currency transactions for your regional trade?
• Is data stored locally in Singapore or in a region that complies with PDPA?

A vendor that hesitates on these answers is a red flag. Singapore’s regulatory environment is not going to get simpler. If your ERP cannot adapt to new compliance rules, you will be stuck with manual workarounds.

2. What Is the True Total Cost of Ownership Over Five Years?

The monthly subscription fee is only the beginning. You need to understand the full cost picture. Use this table to compare vendors side by side.

Cost Category	What to Ask	Why It Matters
Licensing	Per user or per module? Are there minimum seat counts?	A 50-user SME might pay for 100 seats they do not need.
Implementation	How many hours are included? What is the hourly rate for overruns?	Most Singapore SMEs underestimate implementation time by 40%.
Customisation	Is customisation included? Who owns the custom code?	Vendor lock-in often starts with custom code you cannot take with you.
Data Migration	Is data cleaning and migration included?	Dirty data is the top reason for go-live delays.
Training	How many training sessions? Are they in person or online?	Poor training leads to low adoption and failed ROI.
Support	What is the SLA for critical issues? Is support local?	Waiting 48 hours for a fix can halt your entire operation.
Upgrades	Are future upgrades included or billed separately?	Some vendors charge again for version upgrades.

Ask every vendor to give you a five year total cost of ownership (TCO) in writing. Then add a 20% buffer for contingencies. If the vendor resists giving you this number, walk away.

3. Can You Show Me a Reference from a Similar Singapore Business?

Demo environments are polished. Real user experiences are not. Ask for three references from companies in Singapore that are similar to yours in size and industry. Then call them.

Here is what to ask the reference:

• How long did the actual implementation take versus what was promised?
• What was the biggest unexpected cost?
• How responsive is the support team during Singapore business hours?
• If you could start over, what would you do differently?

Do not accept references from overseas companies that are much larger or smaller than yours. A multinational implementation in the US has nothing to do with a 100 person SME in Singapore.

“The best question I ever asked a reference was: ‘What do you wish the vendor had told you before you signed?’ The answer saved us from making the same mistake.” – COO of a Singapore logistics firm, speaking at a 2025 industry roundtable.

4. What Does Your Data Migration Process Look Like?

Data migration is where ERP projects go to die. Your existing data is messy. There are duplicate customer records. Old product codes that no one uses. Spreadsheets with inconsistent formatting. A vendor that glosses over data migration is a vendor that will leave you stranded.

Ask these specific questions:

1. Do you provide a data audit before migration?
2. Who is responsible for cleaning the data? (Spoiler: it should be you, with their tools)
3. What is the timeline for migration? Is it phased or a big bang approach?
4. How do you handle data validation after migration?
5. What happens if data is lost during the process?

A good vendor will be transparent about the effort involved. They will give you a clear data migration plan with milestones. A bad vendor will say “our system imports everything automatically” and leave you to discover the gaps later.

5. How Does Your System Integrate with Our Existing Tools?

No ERP is an island. You likely use a CRM, a payroll system, a bank reconciliation tool, and maybe an e-commerce platform. The ERP needs to talk to all of them.

Ask the vendor:

• Do you have pre-built connectors for the tools we use?
• If not, what is the cost and timeline for building an integration?
• Do you use APIs or do you require middleware?
• Who maintains the integrations when one of the tools updates?

Many vendors will promise “seamless integration” during the sales pitch. But seamless often means “we will build it for an additional fee.” Get the integration scope and cost in the contract.

6. What Is Your Process for Handling Customisation Requests?

Every Singapore SME has unique processes. Maybe you have a special way of handling consignment inventory. Or a specific approval workflow for procurement. The vendor will likely say “our system is highly customisable.”

But customisation comes with a price. Literally.

Ask these questions:

• Is customisation done through configuration (good) or code changes (risky)?
• Who owns the custom code? Can you take it with you if you leave the vendor?
• How do customisations affect future upgrades?
• What is the cost per customisation request?

Configuration is ideal. It means you are using the system’s built in flexibility. Custom code is a trap. It creates technical debt and makes future upgrades painful. If a vendor relies heavily on custom code, ask yourself if their system is truly the right fit.

7. What Happens After Go-Live? Show Me Your Support SLA.

The go-live date is not the finish line. It is the starting point. The first three months after go-live are when most problems surface. Your team will discover gaps. Data will need correction. Users will need retraining.

You need a clear support agreement. Ask for:

• Response times for critical, high, and medium issues (e.g., critical issues resolved within 4 hours)
• Whether support is available 24/7 or only during Singapore business hours
• The escalation process if the first line support cannot solve your problem
• Whether there is a dedicated account manager or a shared support pool
• The process for submitting and tracking feature requests

A vendor that offers local Singapore support is worth a premium. Offshore support can work, but time zone differences and language barriers add friction when you are already stressed.

How to Use These Questions: A Practical Process

You now have the questions. Here is how to use them effectively.

1. Send the questions to all shortlisted vendors before the demo. Ask them to respond in writing. This forces them to think carefully.
2. During the demo, ask them to show you the answers. For example, if they say “we support e-invoicing,” ask them to demonstrate it live.
3. After the demo, compare responses using a scorecard. Rate each vendor on clarity, honesty, and specificity.
4. Call references. Do not skip this step. A 15 minute call can reveal what a dozen emails cannot.
5. Get everything in the contract. Verbal promises are worthless. If it is not in the contract, assume it will not happen.

Red Flags to Watch For During the Process

Here are warning signs that should make you pause:

• The vendor cannot give you a local Singapore reference
• They avoid answering the TCO question
• They say “our system does everything” without specifics
• They pressure you to sign a long term contract before you have done your due diligence
• They dismiss your existing tools and processes as “old fashioned”
• Their support team is not based in Singapore or a nearby time zone

Building Your Selection Committee

You should not make this decision alone. Build a small team that includes:

• A finance representative (to validate costs and ROI)
• An operations lead (to assess daily usability)
• An IT person (to evaluate technical fit and security)
• An end user from the department that will use the system most

Each person should use the seven questions to evaluate the vendors from their perspective. Then compare notes. A vendor that impresses the CFO but frustrates the warehouse team is not the right choice.

Your Next Step

You now have a complete checklist. The seven questions are your shield against empty promises and hidden costs. Use them. Share them with your team. Make every vendor earn your trust with clear, specific answers.

The right ERP vendor will welcome these questions. They will have ready answers. They will provide local references. They will put everything in writing. The wrong vendor will dodge, deflect, or pressure you to sign before you are ready.

Take your time. This is a decision that will affect your business for the next five to ten years. Ask the questions. Verify the answers. Then sign with confidence.
