A bid bond problem in a Philippine government bidding usually comes down to one practical question: Will the Bids and Awards Committee accept my bid security, or will my bid be rejected before the financial proposal is even considered? For bidders, suppliers, contractors, foreign companies, and procurement staff, the safest approach is to understand the official term used in Philippine procurement law: bid security. A bank guarantee is only one possible form of bid security, and it must match the exact form, amount, validity, currency, beneficiary, and wording required in the bidding documents.

What Is a Bid Bond or Bid Security in Philippine Procurement?

In everyday business language, people often say “bid bond.” In Philippine government procurement, the legal term is bid security.

A bid security is a guarantee submitted with a bid to assure the government agency, local government unit, government-owned or controlled corporation, state university, or other procuring entity that the winning bidder will:

Accept the award;
Sign the contract within the required period; and
Submit the required performance security before contract execution.

Under Republic Act No. 12009 (2024), the New Government Procurement Act, all bids under the modes of procurement determined in the Implementing Rules and Regulations must be accompanied by bid security. The law states that the bid security guarantees that, after receipt of the Notice of Award, the winning bidder will enter into the contract and furnish the required performance security. (Lawphil)

In simple terms: the bid security protects the government from bidders who win but later back out, refuse to sign, fail to submit performance security, or otherwise disrupt the procurement process.

Current Legal Basis: RA 12009 and the IRR

The current primary law is RA No. 12009, which revised the old RA No. 9184, the Government Procurement Reform Act. The Implementing Rules and Regulations of RA 12009 apply to procurement by national government agencies, GOCCs, GFIs, SUCs, and LGUs, subject to the exceptions and special rules for foreign-funded procurement, PPP projects, and other excluded activities. (GPPB-TSO)

The most important bid security provisions are found in:

Legal source	Why it matters
RA No. 12009, Section 56	Establishes the requirement for bid security.
IRR of RA No. 12009, Section 56	States the accepted forms, amounts, currency, return, and validity rules.
IRR of RA No. 12009, Section 57	Provides the bid validity rule, including the 120-calendar-day maximum from bid opening.
RA No. 12009, Section 69	Provides forfeiture consequences when the winning bidder fails to post performance security.
Civil Code, Article 2047	Explains the general civil-law concepts of guaranty and suretyship, although government procurement rules control the specific bid security requirements.
GPPB standard forms and Philippine Bidding Documents	Provide the official templates and document wording used by procuring entities.

During the transition to the New Government Procurement Act, procuring entities have been given a three-year transitory period from the approval of the standard forms to fully comply with RA 12009 and its IRR. The GPPB also approved NGPA standard forms for procurement in 2025, including Philippine Bidding Documents and related forms. (GPPB-TSO)

For bidders, this means one practical rule: always follow the posted bidding documents for the specific project. Some agencies may still have legacy formatting during the transition, but the current legal framework is RA 12009 and its IRR.

Bank Guarantee Requirements for Bid Security

A bank guarantee is an undertaking issued by a bank in favor of the procuring entity. If the bidder violates the conditions covered by the bid security, the procuring entity may demand payment from the bank up to the guaranteed amount, subject to the terms of the instrument and procurement rules.

Under Section 56.2 of the IRR of RA 12009, a bidder may submit a bank draft or guarantee, or irrevocable Letter of Credit issued by a bank, in an amount of not less than five percent (5%) of the Approved Budget for the Contract or ABC. If issued by a foreign bank, it must be confirmed or authenticated by a local bank. (GPPB-TSO)

Accepted Forms and Amounts of Bid Security

Form of bid security	Minimum amount
Cash, cashier’s check, or manager’s check issued by a bank	2% of the ABC
Bank draft, bank guarantee, or irrevocable Letter of Credit issued by a bank	5% of the ABC
Surety bond callable upon demand from an Insurance Commission-authorized surety or insurance company	5% of the ABC
Bid Securing Declaration	No cash percentage, but serious consequences if enforced

The bid security must be denominated in Philippine Pesos and posted in favor of the procuring entity. (GPPB-TSO)

Example Calculation

If the ABC is ₱10,000,000, the minimum bid security amounts are:

Form used	Minimum bid security
Cash / cashier’s check / manager’s check	₱200,000
Bank guarantee / bank draft / irrevocable Letter of Credit	₱500,000
Surety bond callable on demand	₱500,000
Bid Securing Declaration	No upfront cash amount, but enforceable penalties apply

A common mistake is using 2% for a bank guarantee. That is incorrect. The 2% rate applies to cash, cashier’s check, or manager’s check. A bank guarantee must be at least 5% of the ABC.

When Is Bid Security Required?

Bid security is required for procurement modes that are competitive in nature, particularly:

Competitive bidding;
Competitive dialogue;
Unsolicited offer with bid matching; and
Limited source bidding.

The IRR states that failure to enclose the required bid security in the prescribed form and amount will automatically disqualify the bid concerned. (GPPB-TSO)

This is why bid security is not a small technical detail. The BAC normally checks it during the preliminary examination of the technical component. If the bid security is missing, insufficient, expired, wrongly worded, not in Philippine Pesos, or not in favor of the correct procuring entity, the bid may fail before price is considered.

Step-by-Step Guide: How to Prepare a Bank Guarantee for a Philippine Government Bid

1. Read the Bid Data Sheet carefully

Do not rely only on the Invitation to Bid. The details are usually in the Bid Data Sheet (BDS) and Instructions to Bidders.

Check:

Project title and project identification number;
ABC;
Required bid security forms;
Exact amount for each form;
Bid validity period;
Deadline and method of submission;
Whether electronic submission is allowed;
Whether original documents must be submitted later;
Name of the procuring entity as beneficiary.

2. Compute the correct amount

For a bank guarantee, compute 5% of the ABC unless the bidding documents require a higher amount.

Formula:

ABC x 5% = minimum bank guarantee amount

For example:

₱8,750,000 x 5% = ₱437,500

Round carefully. Do not submit less than the required amount, even by a small difference. A shortfall of a few pesos can be treated as non-compliance.

3. Confirm that the issuing bank is acceptable

For a Philippine bank, use a bank that can issue bid guarantees or similar instruments for government procurement.

For an LGU procurement, the IRR allows certain instruments to be issued by other banks certified by the Bangko Sentral ng Pilipinas as authorized to issue such financial instrument. The BSP maintains official directories of supervised financial institutions. (GPPB-TSO)

For a foreign bank guarantee, the IRR requires that it be confirmed or authenticated by a local bank. This is a major bottleneck for foreign bidders because local confirmation can take time and may require a credit line, correspondent banking arrangement, or collateral.

4. Ask the bank for the correct wording

The bank guarantee should match the procurement requirement, not merely the bank’s generic commercial format.

At minimum, check that it contains:

Name of bidder;
Name of procuring entity;
Project name and identification number;
Guarantee amount in Philippine Pesos;
Validity period matching or exceeding the required bid validity;
Statement that it is issued as bid security;
Conditions for demand or forfeiture;
Signature of authorized bank officers;
Date of issuance before the bid deadline.

Some banks use conservative wording that may not match the BAC’s expectations. Procurement staff often check not only the amount but also the wording and validity of the security. In Jomadiao v. Arboleda, the Supreme Court discussed the validity of bid security in a procurement case and emphasized that bids should be evaluated based on required documents submitted before, not after, bid opening, to safeguard fair and competitive public bidding. (Supreme Court E-Library)

5. Build in enough lead time

A bank guarantee is not always issued on the same day. Typical practical timing is:

Situation	Practical timeline
Existing credit line with the bank	1–5 banking days
Existing relationship but no guarantee facility	3–10 banking days
New bank client or new credit approval	1–3 weeks or longer
Foreign bank guarantee needing local confirmation	Often 1–3 weeks or longer

Banks may ask for collateral, board approval, secretary’s certificate, specimen signatures, corporate documents, and payment of bank charges. For corporations, delays often happen because the bank wants a board resolution specifically authorizing the bid guarantee and identifying the authorized signatories.

6. Submit the bid security exactly as required

For manual bids, the original bid security is usually placed in the technical component envelope.

For electronic bidding, the IRR allows electronically submitted forms to be considered compliant, subject to the submission of original copies of certain documents, including the Bid Securing Declaration or other forms of bid security excluding cash, and the Omnibus Sworn Statement, during post-qualification. (GPPB-TSO)

Do not assume that a scanned copy is enough unless the bidding documents and the electronic bidding rules allow it.

Bid Securing Declaration vs Bank Guarantee

Many bidders choose a Bid Securing Declaration (BSD) because it does not require cash, a bank line, or collateral at the time of bid submission.

A Bid Securing Declaration is a written undertaking that the bidder will enter into the contract and submit the required performance security within the required period after receiving the Notice of Award. If the bidder violates the undertaking, it commits to pay the corresponding fine and may be automatically disqualified from bidding for government procurement contracts for a period of time upon receipt of the Blacklisting Order. (GPPB-TSO)

Option	Practical advantage	Main risk
Bank guarantee	Stronger financial instrument; often preferred in high-value bids	Requires bank approval, fees, collateral, and correct wording
Surety bond	Often faster than bank guarantee if surety line exists	Must be callable on demand and issued by an authorized surety
Cash / manager’s check	Simple and clear	Ties up cash
Bid Securing Declaration	No upfront cash security	Fine, disqualification, and blacklisting consequences if violated

The procuring entity must indicate at least three acceptable forms of bid security, including the Bid Securing Declaration. (GPPB-TSO)

When Can the Bid Security Be Forfeited?

Bid security may be forfeited when the bidder’s conduct triggers the grounds provided by law, the IRR, and the bidding documents.

Common situations include:

The winning bidder refuses to accept the award without justifiable cause;
The winning bidder fails to sign the contract within the required period;
The winning bidder fails to post the required performance security;
The bidder submits false information or falsified documents;
The bidder commits acts that may lead to suspension or blacklisting;
The bidder violates undertakings in the Bid Securing Declaration.

RA 12009 provides that if the bidder fails to post the required performance security, the bid security shall be forfeited, without prejudice to sanctions under the law. It also provides forfeiture consequences in connection with suspension and blacklisting grounds. (Lawphil)

Bid Validity and Return of Bid Security

The IRR provides that bids and bid securities must be valid for a reasonable period determined by the Head of the Procuring Entity and indicated in the bidding documents. The period must not exceed 120 calendar days from the date of bid opening. (GPPB-TSO)

If the procuring entity needs to extend the bid validity beyond 120 days, it must request the bidders in writing before expiration. Bidders may refuse the extension without forfeiting their bid security. (GPPB-TSO)

Bid securities are generally returned only after the winning bidder has signed the contract and furnished the performance security. For bidders declared failed or post-disqualified, return may depend on submission of a written waiver of the right to request reconsideration or protest. (GPPB-TSO)

Common Reasons Bank Guarantees Get Rejected

Wrong amount

The guarantee must be at least 5% of the ABC. Some bidders mistakenly use 2%, which applies only to cash, cashier’s check, or manager’s check.

Wrong beneficiary

The beneficiary must be the correct procuring entity. A guarantee addressed to the end-user office, BAC chairperson personally, project consultant, or a related agency may create a problem.

Wrong project name or project ID

Procurement offices are strict about matching documents. The project title and identification number should be consistent with the bidding documents.

Validity period is too short

The guarantee must cover the required bid validity period. A bank guarantee expiring before the required date can be treated as insufficient.

Foreign bank guarantee without local confirmation

If issued by a foreign bank, the bank guarantee must be confirmed or authenticated by a local bank. Foreign bidders should not leave this to the last week before bid submission.

Conditional or non-callable wording

If the bank’s wording makes collection too difficult or inconsistent with the bidding documents, the BAC may question it. For surety bonds, the rule expressly requires “callable upon demand”; for bank guarantees, the safest practice is to avoid wording that defeats the purpose of bid security.

Only proof of application was submitted

A bank’s acknowledgment that the bidder applied for a guarantee is not the guarantee itself.

Practical Checklist Before Submitting a Bank Guarantee

Before sealing or uploading the bid, check the following:

The instrument says it is a bid security or clearly secures the bid;
The issuing bank name is complete;
The bidder’s legal name matches SEC, DTI, CDA, or foreign registration documents;
The procuring entity is correctly named;
The project title and project identification number are correct;
The amount is at least 5% of the ABC;
The amount is in Philippine Pesos;
The validity period matches the BDS;
The bank officers signed it properly;
Any required notarization, authentication, or local confirmation is complete;
The original is included if manual submission is required;
Scanned copy and later original submission comply with electronic bidding rules;
The bank guarantee was issued before the bid submission deadline.

Special Issues for Foreign Bidders

Foreign bidders should pay attention to three areas.

First, if the bid security is issued by a foreign bank, the IRR requires confirmation or authentication by a local bank. This is often the most important bank guarantee requirement for foreign participants. (GPPB-TSO)

Second, foreign-funded procurement may follow treaty, international agreement, or executive agreement rules. The IRR provides that if a treaty or international/executive agreement provides a different rule for foreign-funded procurement, that agreement prevails; otherwise, RA 12009 and its IRR apply. (GPPB-TSO)

Third, foreign suppliers and contractors should check eligibility requirements early. For infrastructure projects, PCAB licensing or special licensing issues may arise. The Construction Industry Authority of the Philippines provides PCAB forms, including special license forms for foreign contractors. (Construction Industry Authority)

Foreign documents may also need translation, notarization, consular authentication, apostille, or local certification depending on the bidding documents and the issuing country. The safest practical approach is to compare the foreign company’s documents against the BDS, PhilGEPS requirements, and any clarification issued through bid bulletins.

Documents Commonly Needed to Secure a Bank Guarantee

Banks differ, but bidders are commonly asked for:

Document	Why the bank asks for it
Invitation to Bid and Bid Data Sheet	To verify project details and guarantee amount
Approved Budget for the Contract	To compute the 5% requirement
SEC/DTI/CDA registration or foreign equivalent	To verify legal existence
Board resolution or secretary’s certificate	To confirm authority to apply for and sign the guarantee
Latest financial statements	To assess credit risk
Existing credit facility documents	To determine available line
Collateral documents, if required	To secure the bank’s exposure
Authorized signatory IDs and specimen signatures	To validate instructions
Draft guarantee wording	To align the bank form with procurement requirements

For bid submission itself, the broader technical envelope may include other eligibility and technical documents, such as PhilGEPS registration, Omnibus Sworn Statement, statements of contracts, SLCC, NFCC, PCAB license for infrastructure where applicable, and other documents required by the bidding documents. The GPPB provides NGPA Philippine Bidding Documents and standard forms, including the Bid Securing Declaration, through its official downloadable forms page. (GPPB-TSO)

Frequently Asked Questions

Is a bid bond the same as bid security in the Philippines?

In government procurement, people often use “bid bond” casually, but the official term is bid security. Bid security may be in the form of cash, manager’s check, bank guarantee, irrevocable Letter of Credit, surety bond, or Bid Securing Declaration, depending on the bidding documents.

How much is a bank guarantee for bid security?

A bank guarantee must be at least 5% of the ABC under the IRR of RA 12009. For example, if the ABC is ₱20,000,000, the minimum bank guarantee is ₱1,000,000.

Can I submit a Bid Securing Declaration instead of a bank guarantee?

Yes, if allowed under the bidding documents. The procuring entity must include the Bid Securing Declaration among the acceptable forms of bid security. It avoids upfront bank costs but carries serious consequences if enforced.

What happens if my bid security is missing or insufficient?

The IRR states that failure to enclose the required bid security in the prescribed form and amount automatically disqualifies the bid. This usually means your bid fails at the technical examination stage.

Does a foreign bank guarantee need local authentication?

Yes. A bank guarantee, bank draft, or irrevocable Letter of Credit issued by a foreign bank must be confirmed or authenticated by a local bank.

Can the procuring entity keep my bid security?

Bid securities are generally returned after the winning bidder signs the contract and posts performance security, or for failed/post-disqualified bidders subject to the rules on waiver of reconsideration or protest. However, bid security may be forfeited if the bidder violates the law, IRR, or bid security conditions.

How long should the bid security be valid?

The validity period is stated in the bidding documents. Under the IRR, bids and bid securities may not exceed 120 calendar days from bid opening, unless a proper extension process is requested in writing and accepted by the bidder.

Is a surety bond better than a bank guarantee?

It depends on the bidder’s situation. A surety bond may be faster if the bidder has an existing surety line, but it must be callable upon demand and issued by an Insurance Commission-authorized surety or insurance company. A bank guarantee may be viewed as financially stronger but often requires more bank processing, collateral, and time.

Can a small business bid without tying up cash?

Often, yes. Many small businesses use a Bid Securing Declaration when allowed. But they should understand that violating it can lead to fines, disqualification, and blacklisting consequences.

What should I do if the BDS amount conflicts with my computation?

Follow the bidding documents carefully, but immediately raise the issue through the BAC’s official clarification process before the deadline for requests for clarification. Do not submit a lower amount based only on your own interpretation.
