Documents you need to bid for a tender in Sierra Leone

Many bids in Sierra Leone are rejected not because the price is wrong, but because a document is missing or expired. Most tenders — from ministries, agencies, the World Bank, AfDB, the UN and NGOs — ask for the same core documents. Keep them ready, valid and scanned, and you can respond to a tender in days instead of weeks.

1. The documents almost every tender asks for

Business registration certificate Proof that your business legally exists — from the Corporate Affairs Commission (companies) or the Office of the Administrator and Registrar General (business names). Make sure the name matches exactly the name you use on your bid.

NRA Tax Clearance Certificate Issued by the National Revenue Authority, showing your taxes are up to date. Many notices also ask for your TIN. Tax clearances expire, so check the date before every bid.

NASSIT Clearance Certificate From the National Social Security and Insurance Trust, showing you are paying social security for your staff. Like tax clearance, it must be valid on the bid deadline.

Local Council business licence Your municipal or district council licence, where it applies to your business.

NPPA Supplier Registration Certificate For government tenders, registration on the NPPA e-GP portal is now required to take part in public procurement. Many notices ask for the certificate or proof that you have applied. (See our guide: How to register as a supplier with NPPA in Sierra Leone.)

Audited financial statements Usually for the last two or three years. Larger tenders also set a minimum annual turnover, so check the eligibility section.

Evidence of experience Contracts, purchase orders, completion certificates or reference letters for similar work. Many notices ask for a set number of similar contracts within the last few years.

2. Bid security — what it is and how to provide it

Bid security (also called a bid bond or tender security) protects the buyer if a bidder withdraws their bid or refuses to sign the contract after winning. The tender notice tells you which form is required:

• Bank guarantee — a letter from a commercial bank guaranteeing a fixed amount. The notice states the amount and how long it must stay valid. Large works contracts can require very high amounts; smaller supply tenders much less.
• Bid-Securing Declaration — a signed form instead of money. You promise not to withdraw your bid; if you break that promise, you can be banned from bidding for a period. World Bank and AfDB-funded tenders often use this.

Talk to your bank early — a bank guarantee can take several days to issue. Use the bank guarantee form in the bidding document, not your bank's own template, unless the notice allows it.

3. Documents specific to the tender

Depending on what is being bought, you may also need:

• Manufacturer's authorisation — when supplying branded goods such as vehicles, IT equipment or medical equipment
• Technical specifications, brochures or photos of the exact items you are offering
• Professional certificates — for example a Ministry of Works or construction regulatory registration for works contracts
• CVs of key staff — for consultancy and works contracts
• Site visit certificate — when a site visit is mandatory
• Proof of payment for the bidding document — many tenders charge a non-refundable document fee
• Signed Integrity Pact and beneficial ownership disclosure — increasingly common on government and donor-funded tenders

4. The bid forms themselves

Every bidding document includes forms you must complete and sign: the Letter of Bid (or bid form), price schedules, and sometimes bills of quantities. Use the forms exactly as given, fill in every space, sign and stamp where required, and do not change the wording.

5. Submission: get the basics right

• Follow the format — many tenders ask for one original plus a number of copies, in sealed envelopes marked with the tender reference and "Do not open before…". Some use separate technical and financial envelopes.
• Electronic bids — UN agencies (UNGM, UNDP's Quantum portal) and some ministries accept or require online submission. Read the notice carefully: some say electronic bids are not accepted.
• Beat the deadline — late bids are rejected and often returned unopened. Aim to submit at least a day early.

Your bid-ready checklist

• Business registration certificate
• Valid NRA tax clearance (and TIN)
• Valid NASSIT clearance
• Council business licence (if applicable)
• NPPA supplier registration certificate (government tenders)

• Evidence of similar contracts
• Bid security in the required form
• Tender-specific documents (authorisations, CVs, certificates)
• Completed, signed bid forms and price schedule
• Proof of bid document fee payment

Keep scanned copies of everything in one folder and update the expiry dates every quarter.
