Finding the right tender is only half the battle. The other half — and where most bids are won or lost — is the proposal itself. A well-written, properly structured tender proposal can win contracts even when your pricing isn't the lowest. A poor one can lose you tenders you should have won. This guide shows you exactly how to write one that works.

Understanding How Tenders Are Evaluated
Before writing anything, you need to understand how your proposal will be scored. ZPPA tenders typically use one of two evaluation methods:
- Lowest Price Technically Compliant (LPTC): The cheapest technically acceptable bid wins. Common for straightforward goods and standard services.
- Quality and Cost Based Selection (QCBS): Technical score and financial score are weighted (e.g., 70% technical, 30% price). Common for consultancies and complex services.
Check the tender document carefully — the evaluation method and weightings must be stated. This tells you exactly how much effort to invest in the technical versus financial section.
The Structure of a Winning Technical Proposal
1. Cover Letter
One page. Formal, addressed to the procurement officer by name/title. States clearly that you are submitting a bid, names the tender, and confirms you meet the eligibility requirements. Sign it.
2. Company Profile
Two to three pages. Who you are, when you were registered, what you do, how many people you employ. Include your PACRA registration number. Keep it relevant to the tender — if bidding on a cleaning contract, emphasise your cleaning experience, not your IT capabilities.
3. Understanding of the Requirements
Show the evaluator you have actually read the tender document. Summarise what is being asked for in your own words, then explain why your company is well-positioned to deliver it. This section separates serious bidders from those who submit generic proposals.
4. Proposed Methodology
This is the most important technical section. Explain exactly how you will deliver the work:
- Step-by-step approach to the scope of work
- Equipment, materials or resources you will use
- How you will manage quality
- How you will manage risks
- Your timeline and milestones
Mirror the language of the tender document. If they call it "preventive maintenance," don't write "servicing" — use their exact terminology.
5. Team and Qualifications
List the key people who will work on this contract. For each: name, role, qualifications, relevant experience. Attach CVs for senior staff. Evaluators look for relevant experience — not just qualifications on paper.
6. Past Experience and References
List 3–5 previous contracts of similar scope. For each: client name, contract value, dates, brief description of work done, contact person for verification. This is your proof of capability. If you're a newer business, include smaller projects that demonstrate the same skills.
7. Compliance Documents
Every document on the checklist, in the order specified. Missing a single document can get your bid disqualified before it's even read.
Standard compliance documents for most ZPPA tenders: PACRA certificate, ZRA TPIN, ZRA Tax Clearance, NAPSA certificate, NHIMA certificate. ZamBiz tracks all of these in your Document Vault with expiry alerts.
Writing the Financial Proposal
Present your pricing clearly and professionally:
- Use the pricing schedule format provided in the tender document — don't create your own
- Break down costs clearly (labour, materials, equipment, VAT)
- State clearly whether prices include or exclude VAT (16%)
- Make sure your arithmetic is correct — calculation errors are embarrassing and can cost you points
- Don't leave any line items blank — use 0.00 if applicable
Common Mistakes That Lose Bids
- Generic proposals: Copy-pasting the same proposal for every tender. Evaluators can tell.
- Missing documents: The number one reason for disqualification. Use the checklist.
- Unsigned forms: The bid form, financial proposal and other forms must be signed by an authorised person.
- Expired certificates: A PACRA or Tax Clearance that expired last month will get you disqualified.
- Wrong number of copies: Most ZPPA tenders require original + 3 copies. Submit exactly what is specified.
- Late submission: No exceptions. ZPPA regulations require rejection of any bid received after the deadline.
- Unrealistic pricing: Pricing too low raises quality concerns. Pricing too high loses on cost evaluation.
How to Use Bid Results to Improve
Every time a tender is decided, ZPPA publishes the opened bid results — who submitted, how much they bid, and who won. ZamBiz aggregates this data in the Bid Results section. Use it to:
- See what winning bids looked like on price for similar contracts
- Understand who your regular competitors are
- Calibrate your pricing on the next similar bid
