Most Singapore manufacturers pick an ERP system the wrong way. They attend a demo, the system looks capable, the salesperson is confident, and the price seems reasonable. Six months into implementation, they discover the system does not handle their pricing logic, the local support team has a three-day response time, and the total cost has grown 40% beyond the quote.
Vendor evaluation is the highest-leverage decision in an ERP project. A good system badly implemented is recoverable. A bad system well implemented still fails. This scorecard covers the eight dimensions that actually predict implementation success for Singapore manufacturers.
Dimension 1: Manufacturing Workflow Fit
This is the dimension most manufacturers under-evaluate because demos always look good. The demo shows a clean workflow with sample data. Your operation has custom pricing tiers, non-standard routings, customer-specific documentation requirements, and subcontractor loops that the demo never shows.
The test: bring your three most complex jobs to the demo. Ask the vendor to show how the system handles a quote with customer-specific pricing and multiple line items with different lead times. Ask how a job card is created when an order is accepted. Ask how subcontractor status is tracked. If the vendor cannot demonstrate these in the demo environment — with your scenarios, not theirs — the fit is weaker than the pitch.
Dimension 2: Singapore Compliance Coverage
- Singapore compliance requirements to verify:
- InvoiceNow / PEPPOL BIS Billing 3.0: is this native output or a third-party add-on?
- GST F5 report: does the system generate the IRAS-format report directly?
- Multi-currency: Singapore manufacturers often invoice in USD, EUR, or AUD alongside SGD
- CPF and payroll integration: if the system includes HR, does it handle CPF correctly?
- EDG / PSG documentation: can the vendor provide documentation for grant applications?
Dimension 3: Implementation Approach
There are two fundamentally different implementation approaches: fixed scope (the vendor delivers a defined system for a defined price) and time-and-materials (you pay for hours). Fixed scope transfers risk to the vendor; time-and-materials transfers risk to you.
For Singapore SMBs without internal IT teams to manage scope creep, fixed scope is almost always preferable. Time-and-materials implementations rarely come in at budget. Ask every vendor: is this a fixed-scope engagement, and what happens if scope changes are needed?
Dimension 4: Total Cost of Ownership — Three Years
- Three-year cost components to calculate:
- Year 1: licence fee + implementation + training + data migration + any customisation
- Year 2: annual licence/maintenance + any post-go-live enhancements + internal IT time
- Year 3: same as year 2 + upgrade costs if a major version change is due
- Exit cost: cost of migrating data out if you leave the vendor (often excluded from TCO calculations but material for SaaS platforms)
The three-year number is almost always more revealing than the year-one quote. A system that costs S$30,000 in year one but S$25,000 per year in maintenance compares very differently to a S$50,000 custom build with zero ongoing licence fees.
Dimension 5: Local Support Quality
Singapore-based support matters more than most manufacturers anticipate during vendor selection. When the production system goes down at 7am on a Monday and the support team is in the US or India, the response time SLA in the contract is cold comfort. Ask specifically: who is the support team for Singapore customers, where are they based, and what is the contractual response time for production-stopping issues?
The best way to test support quality is to submit a pre-sales technical question through the support channel — not to the salesperson — and time the response. A vendor who responds in four hours pre-sales will be faster than one who takes two days, but the ratio tends to hold post-sale.
Dimension 6: Reference Customers
Ask for three Singapore manufacturer references at similar scale and complexity. Not case studies on the website — actual contacts you can call. Ask them: did the implementation come in on time and budget? How long did it take to reach stable daily use? What did you wish you had known before starting? Would you choose the same vendor again?
A vendor who cannot provide three Singapore references in manufacturing is either new to the Singapore market or has a reference problem. Both are flags.
Dimension 7: Data Ownership
Data ownership is rarely discussed during vendor selection and frequently becomes a crisis later. The questions to ask: who owns the data in the system — you or the vendor? If you stop paying the licence, can you export a full copy of your data in a standard format (CSV, JSON, SQL)? Is there a contractual data portability clause? How long does the vendor retain your data after contract termination?
SaaS platforms vary significantly on this. Some provide clean data exports on request; others make extraction difficult by design. For a manufacturer with five years of production history, customer pricing agreements, and supplier relationships in the system, data portability is not a nice-to-have.
Dimension 8: Post-Go-Live Flexibility
Every manufacturer discovers within six months of go-live that one or two things need to change — a new report, a modified workflow, an additional field on the job card. The cost and speed of making those changes varies by orders of magnitude between vendors.
For packaged ERP systems, post-go-live changes require the implementation partner, typically at consulting rates of S$150-300/hour. A change that takes a developer two hours costs S$300-600 plus project management overhead. For custom-built systems, changes are made directly by the original developer with no vendor intermediary. Ask vendors for the cost of three specific post-go-live scenarios before signing.
