Understanding Tender Types: RFQ, RFP, RFB, RFI, and EOI Explained
What is the difference between an RFQ, RFP, RFB, RFI, and EOI? This guide explains each government tender type, when they are used, and how to respond to each one.
Overview of Tender Types
South African government procurement uses several types of tender documents, each suited to different purchasing needs. Understanding the differences helps you decide which opportunities to pursue and how to respond.
RFQ — Request for Quotation
What It Is
An RFQ is the simplest form of procurement. The government knows exactly what they want and is asking for your best price.
When It Is Used
- Purchases below R500,000 (the threshold for formal tendering)
- Standard goods or services with clear specifications
- Three or more quotes are typically required
How to Respond
- Focus on price — the lowest compliant quote usually wins
- Keep your response brief and focused on the requirements
- Turnaround is fast, often 3-7 days
- No lengthy technical proposals needed
Example
"Supply and delivery of 50 desktop computers with the following specifications..."
RFP — Request for Proposal
What It Is
An RFP is used when the government has a problem to solve but is open to different approaches. They want to see your methodology, not just your price.
When It Is Used
- Complex services like consulting, IT systems, or professional services
- The buyer values approach and expertise, not just cost
- Usually above R500,000
How to Respond
- Include a detailed methodology showing how you will deliver
- Provide CVs of key personnel who will work on the project
- Demonstrate relevant experience with similar projects
- Price is important but weighed against technical merit
- Responses are typically 20-100 pages
Example
"Appointment of a service provider to develop and implement an integrated HR management system..."
RFB — Request for Bid (Open Tender)
What It Is
An RFB is the most formal procurement process. It is a fully advertised, competitive tender open to all qualifying suppliers.
When It Is Used
- High-value procurement, typically above R500,000
- Infrastructure, construction, large supply contracts
- Must follow the full PPPFA (Preferential Procurement Policy Framework Act) process
How to Respond
- Complete every section of the bid document — incomplete bids are disqualified
- Attach all required documents (tax clearance, BBBEE certificate, CSD registration)
- Attend the compulsory briefing session if one is specified
- Submit before the closing date and time — no late submissions
- Responses can be 100+ pages with appendices
Example
"Construction of a new community health centre in Limpopo Province..."
RFI — Request for Information
What It Is
An RFI is not a tender. It is a market research exercise where the government gathers information before issuing a formal tender.
When It Is Used
- The government is exploring options for a future procurement
- They want to understand available solutions, pricing ranges, or market capacity
- No contract is awarded from an RFI
How to Respond
- Participate — it influences the future tender specifications
- Share your capabilities and approach
- Do not provide firm pricing (it is non-binding)
- Keep it concise — this is information sharing, not a bid
Example
"The Department seeks information on available fleet management solutions to inform a future procurement process..."
EOI — Expression of Interest
What It Is
An EOI is a pre-qualification step. The government asks suppliers to express their interest and demonstrate their capability before shortlisting for a formal tender.
When It Is Used
- Large, complex procurements where the government wants to shortlist capable suppliers
- Often followed by an RFP or RFB sent only to shortlisted suppliers
- Common in construction, consulting, and specialised services
How to Respond
- Demonstrate your qualifications and experience
- Provide references from similar projects
- Show your capacity to deliver (team size, equipment, financial resources)
- This is your chance to get shortlisted — a strong EOI leads to a tender invitation
Example
"Expression of Interest for the appointment of a panel of quantity surveyors for a period of 36 months..."
Quick Comparison
| Type | Complexity | Value | Timeline | Key Focus |
|---|---|---|---|---|
| RFQ | Low | Under R500K | 3-7 days | Price |
| RFP | High | Over R500K | 3-6 weeks | Methodology + Price |
| RFB | High | Over R500K | 3-8 weeks | Compliance + Price |
| RFI | Low | N/A | 2-4 weeks | Information only |
| EOI | Medium | Varies | 2-4 weeks | Capability |
Tips for All Tender Types
- Read the entire document before starting your response
- Check the mandatory requirements — missing one can disqualify you
- Follow the format requested — if they want sections numbered 1-5, number them 1-5
- Attend briefing sessions — they are often compulsory and always informative
- Submit early — do not wait until the last hour
