How Much Does a Custom ERP Cost & How Long to Build? (Singapore 2026)

A custom ERP costs from $30,000 for the Starter tier with 3–5 modules, $50,000–120,000 for the Standard tier with 6–10 modules, and $120,000–250,000+ for the Enterprise tier with 10+ modules. Build timelines run 3–5 months, 5–9 months, and 9–15 months or more respectively. Maintenance is 15–20% per year.

How much does a custom ERP cost?

FutureTech's custom ERP pricing follows module count and is published openly in USD for the Singapore market.

Tier	Modules	Typical scope	Price (USD)	Timeline
Starter ERP	3–5	Inventory, purchasing–sales, basic accounting	From $30,000	3–5 months
Standard ERP	6–10	Adds HR, CRM, production/projects, BI	$50,000–120,000	5–9 months
Enterprise ERP	10+	Multi-branch, multi-entity, deep custom workflows	$120,000–250,000+	9–15 months+

The range is wide because an ERP is not a boxed product. It is a set of modules assembled to match how your business actually runs. A retailer tracking stock across three outlets needs a fundamentally different build than a manufacturer managing bills of materials.

What determines the price of your ERP?

Five factors drive the quote: module count, integration count, data migration volume, permission complexity, and post-launch support level.

• Module count: starting with inventory and sales costs far less than tackling HR, finance, and production at the same time.
• Integrations: connecting accounting software, e-commerce channels, payment gateways, or legacy databases adds development and testing time.
• Data migration: moving five years of transaction history from spreadsheets or an old system takes longer than starting fresh.
• User complexity: multi-branch permission structures and approval workflows add configuration work.
• Support: maintenance runs 15–20% of the contract value per year for bug fixes, security updates, and minor adjustments.

This is also why a $30,000 quote and a $200,000 quote can both be accurate for the same industry. They simply assume different scopes. Ask every vendor to itemize scope before comparing numbers.

How is the cost calculated by module?

Project price is roughly team composition (people × role × seniority) × months × published staff rates of $1,500–2,900 per person per month, a formula you can verify yourself.

A Starter ERP, for example, corresponds to a team of 4–5 people (backend, frontend, QA, project management) working for 3–5 months. Multiply by the published rates and you arrive at the from-$30,000 figure. Note that cost does not scale linearly with modules. A 6-module ERP costs meaningfully more than double a 3-module one, because every new module must exchange data with the existing ones. Adding HR, for instance, means wiring payroll into departmental costs and financial reporting.

A practical way to budget is to start with the 2–3 modules that solve your most urgent pain, usually inventory or sales, go live, then add modules in phases as the system proves its value. FutureTech structures projects exactly this way to keep early spend predictable.

If you only need one workflow, do you need an ERP at all?

No. A single-workflow industry app starts at just $10,000–24,000 for the Basic tier (5–10 weeks), a different price range from an ERP at $30,000+.

If all you need is warehouse management, or just a sales tool, do not pay for a full ERP. An ERP becomes the right investment only when several workflows must run on one shared data source.

How long does a custom ERP take to build?

The Starter tier takes 3–5 months, the Standard tier 5–9 months, and the Enterprise tier 9–15 months or more. Timelines follow modules and integrations, not company size.

The typical phases of a project:

• Discovery and scoping (2–4 weeks): mapping current workflows, defining modules, confirming integrations.
• Design and architecture (2–6 weeks): data models, user roles, cross-module flows.
• Core development (6–20 weeks): building modules in priority order, usually inventory and sales before finance and HR.
• Data migration and integration (2–8 weeks): often running in parallel with development.
• Testing and UAT (2–4 weeks): acceptance testing with real staff, not just the project team.
• Go-live and stabilization (2–4 weeks): phased rollout, monitoring, quick fixes.

Starter builds compress these phases into 3–5 months. Multi-branch projects, or those with compliance requirements in healthcare or finance, substantially extend testing and migration.

Can the EDG grant reduce your custom ERP cost?

Yes. EDG covers up to 50% of qualifying project costs and has no pre-approved vendor list, so a Vietnam-based partner like FutureTech qualifies.

Two conditions matter here. The project must not start before the application is approved, and PSG only covers pre-scoped packaged solutions, so fully custom ERP goes through EDG. FutureTech helps prepare the technical scope documents; verify current conditions against the official guidelines before budgeting the grant in.

FAQ

Is $30,000 enough for a working ERP? Yes, for a Starter scope: 3–5 core modules such as inventory, purchasing–sales, and basic accounting for a single location, delivered in 3–5 months. Advanced multi-branch logic or heavy third-party integrations push the project into the Standard or Enterprise tier.

Why do ERP quotes vary so much between vendors? Because each quote assumes a different scope, not a different pricing philosophy. A 3-module quote with no integrations will always be lower than a 6-module quote with data migration. Request an itemized scope before comparing.

Can I build an ERP in phases to spread out the cost? Yes, and it is generally the soundest approach financially: go live with the 2–3 highest-priority modules, then add HR, finance, or advanced reporting later. Early spend stays predictable and you validate ROI before expanding.

Does a longer timeline always mean a higher cost? Usually, since both scale with complexity, but not strictly. A project can run long due to slow decisions or scope changes without the engineering cost rising proportionally.

What costs continue after go-live? Annual maintenance of 15–20% of the contract value, covering bug fixes, security updates, operational support, and minor adjustments. Major upgrades are quoted separately. Budget it as a recurring cost.

As a Vietnam-based team delivering for the Singapore market, FutureTech pairs pricing four to six times below a local agency with ISO 27001 certified information security, Singapore-hours collaboration in English, and full source-code and IP handover, so the cost saving never trades away control of your data.
