The complete guide to GeBIZ: Singapore's government procurement portal

What is GeBIZ?

GeBIZ (Government Electronic Business) is Singapore's centralised government e-procurement portal, operated by the Ministry of Finance (MOF). Every Singapore government agency — ministries, statutory boards, and government-linked entities — is required to publish procurement opportunities on GeBIZ above certain thresholds.

Launched in 2000, GeBIZ processes billions of dollars in public sector spending annually. It is the single most important procurement portal for any vendor selling to Singapore's public sector.

What GeBIZ publishes:

• Open Tenders — competitive bids open to all eligible vendors, typically for contracts above S$90,000
• Invitations to Quote (ITQ) — smaller value purchases, typically S$6,000–$90,000, sent to a shortlist of vendors
• Invitations to Tender (ITT) — larger, more complex procurements with detailed specifications
• Awarded contracts — the outcome of completed procurement exercises, including vendor name, contract value, and duration
• Tender amendments — changes to existing tender specifications or closing dates

Who buys on GeBIZ?

Understanding which agencies buy what matters as much as knowing which tenders are open. Here are the most active GeBIZ buyers by category:

How to register as a GeBIZ Trading Partner

To bid on tenders published on GeBIZ, your company must register as a GeBIZ Trading Partner. This is a one-time process, but it requires specific documentation.

What you need:

• Singapore-registered company (ACRA registration number required)
• CorpPass account for your company (used to authenticate on GeBIZ)
• Valid UEN (Unique Entity Number)
• Bank account details for payment purposes
• GeBIZ Trading Partner registration (free, applied for via GeBIZ portal)

Foreign companies note: Foreign companies without a Singapore-registered entity cannot register directly as GeBIZ Trading Partners. You will need to operate through a Singapore-incorporated subsidiary or a local partner. Some tenders, particularly in IT services, may still allow foreign firm participation through partnerships.

The registration process typically takes 3–5 business days. Once approved, you can receive ITQs directly via GeBIZ and submit bids online.

Understanding Singapore procurement thresholds

Singapore's procurement thresholds determine how agencies must procure goods and services. Understanding these affects your bidding strategy:

For most vendors, the open tender threshold (S$90,000+) represents the bulk of accessible opportunities. ITQs are invitation-only — agencies must invite you directly. However, being a registered Trading Partner and maintaining an updated profile increases your chances of receiving ITQ invitations.

The GoBusiness alert problem — and what to do now

Until 2025, many Singapore vendors relied on GoBusiness Business Grants Portal email alerts to be notified of new GeBIZ opportunities relevant to their business category.

Singapore's government discontinued this alert service in early 2025 as part of a digital services rationalisation. The result: thousands of vendors who depended on email alerts now have no automated notification system for new tenders.

The remaining options are:

• Manual GeBIZ checks — logging in 2–3 times per week to search for relevant tenders. Time-consuming and easy to miss opportunities.
• Third-party monitoring services — some procurement agents offer manual monitoring, but at significant cost.
• Hook — continuous automated monitoring with plain-English search, structured output, and real-time alerts. Replaces the GoBusiness alert service directly.

How to search GeBIZ effectively

GeBIZ's native search is keyword-based. This creates a well-known problem: government agencies often describe tenders in procurement language that doesn't match vendor language. A cybersecurity audit becomes "ICT security assessment." A cloud migration becomes "infrastructure modernisation."

Tips for better GeBIZ keyword searching:

• Search by agency code (e.g., "GVT" for GovTech, "MOH" for Ministry of Health) to see all open tenders from specific buyers
• Use procurement category filters to narrow by industry type (IT, Construction, Professional Services)
• Check awarded contracts to understand what agencies have bought before — this predicts what they'll buy next
• Set your Trading Partner profile categories accurately — ITQs are matched to profile categories
• Search on Tuesday and Thursday mornings — new tenders tend to be published at the start of the work week

The fundamental limitation is that GeBIZ keyword search is brittle. Hook solves this with natural language understanding — you ask in plain English, and Hook finds semantically relevant tenders regardless of how the agency wrote the title.

Common GeBIZ questions for vendors

Singapore's government procurement calendar

Understanding the Singapore budget cycle helps predict when new tenders are likely to be published:

• February: Singapore Budget is tabled in Parliament. Agencies receive their budget allocations for the fiscal year (April–March).
• April–June: First wave of new tenders for the fiscal year. High volume period as agencies start spending their annual budgets.
• July–September: Mid-year period. Agencies assess mid-year spending and may issue additional tenders or amendments.
• October–December: Year-end push. Agencies rush to commit remaining budget before the fiscal year ends. High volume of tenders, often with shorter closing timelines.
• January–March: Wind-down and transition. Existing contract renewals, new fiscal year preparation.

The October–January period tends to be the most active for IT services and professional services tenders, as agencies rush to utilise remaining budget.

How Hook helps Singapore vendors

Hook is an AI-powered search tool that sits on top of GeBIZ. Instead of logging in to GeBIZ and running keyword searches manually, you ask Hook in plain English.

Example queries Hook understands:

• "Show me cybersecurity tenders closing in the next 30 days"
• "What IT contracts has GovTech issued above $1M this quarter?"
• "Find cloud infrastructure tenders from statutory boards"
• "Which agencies are looking for managed services providers?"

Hook returns structured results: tender ID, agency, title, value, and closing date — formatted for direct import into your CRM or pipeline. No copy-paste. No reformatting.

Hook also monitors GeBIZ continuously. New tenders appear in Hook within minutes of posting. For Singapore vendors, this replaces the discontinued GoBusiness alert service and manual daily checks.
