Construction contractors, large-scale manufacturers, and leading suppliers win contracts through competitive bidding. Clients can structure the bidding process in several ways, but the two most crucial methods of soliciting remain: sending a request for proposal RFP or a request for bid and extending an invitation to bid ITB. The RFP and ITB look similar, but they share significant differences.

Invitation to Bid ITB

An invitation to bid (invitation for bids) is usually a sealed bidding process, used when project needs are clearly defined and understood. So, the invitation to bid evaluations is determined using pricing. Albeit an invitation to bid values the vendors’ experience, an organization using this method will already have a detailed description of its project and the proposer’s qualifications.

An invitation to bid uses a sealed bidding process of soliciting bids from different service providers (or vendors), especially when there’s no difference between the products and services that meet set specifications. The only real discrepancy between the ITB submissions is the pricing.

The central purpose of an invitation to bid is to provide standardized information to different bidders, thereby fostering a truly competitive bidding process. Sealed bidding procedures promote fair competition and equality.

Contractors and vendors will submit their prices in sealed envelopes. The sealed proposals and quotations received are opened and displayed publicly to maintain transparency and accountability. The contract is then awarded to the lowest bidder without negotiations about services or pricing.

When to Use an Invitation to Bid

An invitation to bid is useful for predictable projects and works. For instance, when the contracting agent or client has clear expectations and well-defined project goals. The invitation to bid includes providing detailed information and written specifications. An invitation to bid will typically involve some fixed-price contract.

Indeed, most public work projects are required by law to use a competitive bidding process. The rationale behind this edict is to keep the public procurement process simple, transparent, and fair to all parties. This is because government contracts should be awarded without favoritism to avert corruption and graft.

Advantages of the Invitation to Bid

Invitation to bid is a straightforward process to assess providers and award a contract. This process simplifies the procurement procedure by outlining the desired end product. The invitation to bid is helpful when considering many bidders because there are no differences in bids, only in prices.

Disadvantages of the Invitation to Bid

The disadvantage of the invitation to bid is that the company’s performance and track record are not evaluated. Awarding a contract based on pricing alone is a risky procurement move. Looking at the price as the sole evaluation metric could lead to suppliers lowering prices or underbidding to win contracts. So, clients must reconcile the pros and cons of the invitation to bid process to get the best from their bucks.

Request for Proposal RFP

A Request for Proposal RFP or request for bid is used on complex projects, unlike an invitation to bid. These projects demand a high level of technical expertise. In addition to pricing, experience, technical capacity, and approach are critical elements of the RFP process. Due to its long and strenuous process, the request for proposal leads to a longer bidding and selection process. There’s also a potential for negotiation breakdown.

A request for proposal reflects a competitive method of soliciting proposals from different vendors. This model of procurement is used when the end product is unique. The RFP is used when the client knows exactly what they want, but the procedures aren’t readily available. So, in RFP, pricing and budgetary issues aren’t the primary concerns. Experience and quality are factored in the contract negotiation process.

The request for proposal usually highlights a range of specifications. It describes generic specifications, the desired end-product, and the evaluation criteria. These specifications allow prospective contractors to offer different solutions, methods, and price points for customers to assess. The contract is then awarded, or the pool of contractors is reduced, and negotiations start. The final contract is awarded based on price and quality.

When to Use a Request for Proposal

A request for proposal is used for big-ticket, sophisticated projects. Typically, a request for proposal is used for projects that require a large number of technical requirements. The whole point of using an RFP is that it’s “process-sourcing” as opposed to the ITB which is “price-sourcing”. A request for proposal allows contractors to propose different ways of performing a task – not based on price but purely based on work specifications, experience, and expertise.

Advantages of the Request for Proposal

One of the greatest advantages of the RFP is that it’s based on the “best bang” for the “best-buck” theory. This means the best price denotes the highest quality. According to the RFP, expertise and performance are key ingredients of quality work; negotiation is a means to obtain the best value. RFP allows for easier project customization and increased innovation by leaving implementation to the appropriate parties.

Disadvantages of the Request for Proposal

One disadvantage of using the request for proposal is its extended formal process. The evaluation and assessment of each contract proposal can be time-consuming and tedious, and negotiations can take longer than expected. But as mentioned, this expense and “front-end” time leads to innovation and lower overall costs.
