Invitation for bid (IFB): sealed lowest-price buying, and what a responsive ride bid must include

What an invitation for bid is

An IFB is a purchase decided on price alone among bids that meet the specifications. FAR 14.101 lays out the steps: the invitation describes the requirement clearly and completely, it is publicized, bidders submit sealed bids, bids are evaluated without discussions, and the award goes to the responsible bidder whose conforming bid is most advantageous to the government, considering only price and the price-related factors in the invitation. The bids are opened in public.

FAR 6.401(a) says to use sealed bids when four things are true: time permits, the award can rest on price and price-related factors, no discussions are needed, and more than one bid is expected. The overhauled FAR that VA now applies keeps the same four conditions and adds that sealed-bid contracts are firm-fixed-price, or fixed-price with an economic price adjustment when some flexibility is needed.

A request for quotation is the quick version for smaller buys. A request for proposals lets the buyer weigh factors besides price and negotiate. The whole bidding process, from finding the notice to the award, is in government NEMT contracts.

Where ride services are bought by IFB

State and local buyers use it for ride work. Three examples:

• Arkansas Medicaid. The Department of Human Services issued IFB 710-25-049 on June 5, 2025, to buy a transportation broker for each of seven regions. Bidders gave a per member per month base rate for each region, and bids were opened by video conference on July 7, 2025. The state wrote that awards would go to the lowest responsive and responsible bidder per region, and posted the anticipated award for 14 days before issuing contracts. See the Central Arkansas Development Council guide for the Region E result.
• Los Angeles County. The Department of Children and Family Services released an IFB on November 16, 2023 for school-of-origin transportation for foster youth, with a one-year term and two one-year options and rates held firm for the term. It examined price sheets for the lowest price, and a granted local small business, social enterprise or disabled veteran preference could deduct up to 15 percent of the lowest bid, capped at $150,000.
• Local governments. Massachusetts chapter 30B section 5 sets sealed bidding for local contracts above $50,000, or $100,000 for school districts, with exceptions in other sections.

Federal ride buyers pick other methods. VA’s Hines and Spokane buys in 2026 were RFQs, and its Altoona buy was an RFP that weighed past performance above price. See the government contracts guide for where each type is posted.

What makes a ride bid responsive?

A responsive bid meets every material requirement of the invitation, and a bid that does not is thrown out, however low it is. FAR 14.301 says a bid must comply in all material respects. A bidder that uses its own form or a letter must accept all the terms and conditions. Arkansas’s IFB shows what that means for a ride company:

• Price sheet. Prices only on the official sheet, sealed apart from the rest of the bid. Failure to complete and submit it meant disqualification, and each regional rate had to fall within the range printed on that region’s sheet.
• Price hold. Prices valid for 120 days after the opening.
• Qualifications. Registration and good standing in the state by the contract start, with a certificate of good standing on request, and at least five years of NEMT experience.
• Bond. A letter from an admitted surety offering to guarantee 100 percent of the annual contract price, submitted with the bid, and the performance bond itself at contract start. Our surety bond guide covers how to get one.
• Amendments. Anything posted within three calendar days before the opening extended the opening, so check for amendments until the last day.

Missing small details are not always fatal. FAR 14.405 lets the contracting officer cure or waive a minor informality, such as an unsigned bid that is accompanied by a bid guarantee, or a missing acknowledgment of an amendment when the bid shows the amendment was received.

What does responsible mean?

It means the company can do the job. FAR 9.104-1 lists adequate financial resources, the ability to meet the schedule, a satisfactory performance record, a record of integrity, the organization, experience and controls to perform, and the necessary equipment and facilities. A company with no relevant performance history cannot be found nonresponsible solely for that. The Arkansas IFB turned the idea into minimum qualifications that bidders had to meet before price counted.

Lowest does not mean any price. Arkansas issued a second IFB for Region G alone on June 19, 2026 (710-26-069), where bidders offer a percent below the calendar year 2027 per member per month rate and the lowest percent wins. The same document lets the state treat a price as unrealistic, meaning too low to show the bidder can meet the requirements. The state may ask for clarification and remove the bidder from consideration.

What happens on a tie?

The buyer’s tie rule decides, because identical sealed bids are common when a price has a floor. Under FAR 14.408-6, equal low bids go first to small businesses that are also in labor surplus areas, then to other small businesses, then to others, and any remaining tie is settled by drawing lots witnessed by at least three people.

Arkansas shows it on a larger scale. The July 7, 2025 tabulation has four bidders at $3.44 in Region A. On July 11, 2025, state staff flipped coins, in front of witnesses, to settle ties in Regions A through D and G. In Regions E and F the record says no coin flip was required under rule R8:19-11-229(3) because an Arkansas company was among the tied bidders, and the award went to that company.

What if the price is wrong?

Report it before the opening if you can, because afterward the options narrow. After opening, FAR 14.407-1 has the contracting officer check bids for mistakes and ask a suspicious bidder to verify. Under 14.407-3, correction needs clear and convincing evidence of the mistake and the bid actually intended, and it cannot be used to make a nonresponsive bid responsive. Massachusetts law lets a bidder correct, modify or withdraw by written notice before opening. Afterward, minor informalities are waived, and a mistake that is evident on the bid’s face is corrected by the buyer, in which case the bid cannot be withdrawn.
