How to Choose the Right Vendor: A Procurement RFP Guide

For small businesses, choosing the right vendor can be the difference between booming success and a severe setback. A request for proposal (RFP) is a practical tool that can help small business owners compare vendors, make informed decisions, and reduce their risk.

Our guide below discusses when to use an RFP, how to write one, the best way to evaluate vendors, and how to professionally communicate your decision.

What is an RFP?

An RFP is a formal document that businesses use to invite vendors to propose how they would solve a business need or complete a project. RFPs often include details like the project scope, your company’s background, timeline, and budget, to name a few. Unlike an RFI (request for information) or an RFQ (request for quotation), an RFP asks vendors to propose a solution—not just provide information or pricing.

Let’s say you own a bakery and want to hire a company to add an online ordering system to your website. You can create an RFP outlining your goals and requirements, then invite vendors to submit proposals explaining their recommended solution, pricing, timeline, and qualifications. After comparing multiple proposals, you can choose the vendor that best fits your needs.

When should a small business use an RFP?

As a small business, not every project or purchase will benefit from an RFP. If you are looking to replace the office printer or get marketing supplies printed, you can often compare a few quotes and get by just fine. An RFP is beneficial when your project stakes are bigger and involve investments, customization, or outside influences.

It may be in your best interest to use an RFP when:

• You’re making a big purchase. If you’re investing a lot of money — and resources — into a project, an RFP helps you compare proposals so you can choose the vendor that offers the best overall value.
• You need specialized expertise. Whether you are implementing new software or hiring a marketing agency, an RFP gives you the opportunity to compare vendors' experience and qualifications before making a decision.
• Your project is complex. If there are multiple ways to solve your business need, an RFP gives vendors the opportunity to explain their approach. This allows you to choose which solution best fits your business goals.
• You aren’t the only one making the decisions. If your small business has stakeholders to answer to, an RFP can help give you the backing you need to promote your decision and come to a unanimous agreement.

How to write an RFP: A step-by-step guide

The key to getting well-qualified vendors to submit bids on your project is a thorough RFP that clarifies expectations and terms up front. Here are the key elements every vendor RFP should include, along with guidance for completing each section. These steps can serve as a template that helps vendors prepare accurate, comparable proposals.

Introduce your company and the project

According to Matias Rodsevich, CEO and Founder of PRLab, your RFP should help prospective vendors understand the business problem behind the request for services. 

"Vendors propose better solutions when they understand the problem, not just the ask," he said.

Your RFP should start with a brief overview of your company, industry, and mission, along with the reason you're issuing the RFP. Rodsevich also advised explaining what’s not working about your current approach, whether it’s an inefficient internal process or an existing vendor that you’re looking to replace.

Questions to answer:

• Who is your company, and what does it do?
• What challenge or opportunity prompted this project?
• Why are you seeking a vendor now?

Define your project scope and budget

This is the “meat” of your RFP and the most important section for vendors who want to submit a bid. Here, you’ll need to describe the project's objectives, the deliverables you expect, the anticipated duration, and the budget for the project. 

“Vague budgets get you either lowball proposals that can't deliver or padded ones that assume you have more to spend than you do,” said Rodsevich, who emphasized that your RFP should include a firm budget ceiling or range.

He also noted that defining what falls outside the scope of your project in this section can help prevent misunderstandings before you hire a vendor.

“That one line saves you from scope creep and surprise invoices later,” Rodsevich added.

Sharing all of this information upfront lets vendors tailor proposals that realistically fit your business needs and constraints. It also helps eliminate vendors that aren't the right fit before you spend time evaluating proposals.

Questions to answer:

• What are the project's primary goals?
• What deliverables do you expect?
• What is outside the project's scope?
• What budget or budget range do you have in mind for the project?

Outline your submission timeline and requirements

This section of your RFP should include a clear schedule for the procurement process, including the deadlines for proposal questions and submissions, as well as the anticipated project kickoff. 

"Vendors work around dates, so give them real ones,” Rodsevich told CO—.

Then, explain exactly how proposals should be submitted, including formatting requirements, page limits, and the appropriate point of contact for questions. Clear submission instructions help reduce confusion and minimize repetitive clarification requests.

Questions to answer:

• When are vendor questions due?
• When must proposals be submitted?
• When do you expect work to begin?
• What format should proposals follow?
• Who should vendors contact with questions?

Explain how proposals will be evaluated

Rodsevich encouraged business owners to be transparent about the selection process from the outset. 

"If vendors know how they'll be judged, they write tighter proposals," he said. 

Outline the evaluation criteria you’ll use—such as price, technical capabilities, industry experience, or customer support—and assign each category a relative weight. If applicable, Rodsevich also recommended including any legal, security, privacy, or compliance requirements that vendors will need to meet before entering into a contract.

Questions to answer:

• What criteria will proposals be evaluated against?
• How important is each criterion?
• What legal, compliance, or security requirements must vendors meet?

How to evaluate vendor responses and score proposals

Once proposals start coming in, these tips can help you develop a consistent, fair evaluation process for each:

Use consistent scoring criteria

First, evaluate every proposal against the weighted criteria outlined in your RFP.

“I usually score each proposal against three to five categories: cost, technical or strategic fit, relevant experience, and team quality,” Rodsevich said. “Don’t invent new [criteria] after the fact; that’s how bias creeps in.”

Rodsevich also suggests having multiple people score each proposal independently, then compare.

“You’d be surprised how often two people read the same proposal completely differently, and that gap is useful information,” he told CO—.

Look beyond the written proposal

Next, have a conversation with your finalists to evaluate how they communicate and how the relationship might unfold. Angela Petulla, Vice President of Marketing at altLine by The Southern Bank, advised using these discussions to evaluate how easily a vendor fits into your workflows, how they plan to communicate with you, and whether they’re flexible enough to adapt to changing priorities.

“These are all just as important considerations as price and expertise, in my opinion,” said Petulla. 

Be aware of red flags

As you compare finalists, Rodsevich recommends keeping an eye out for the following warning signs:

• Proposals with vague language, e.g., “driving results” instead of detailing what they’ll do or how they’ll do it.
• Bids that are significantly lower than those of their competitors.
• Vendors who don’t ask questions or otherwise engage specifically with your business.

Finally, confirm that the people presented during the proposal process are the same people who will perform the work.

How to negotiate with your chosen vendor

Before signing any agreements, take time to clarify expectations and negotiate terms that work for both parties, including:

• Pricing and payment. In addition to total cost, discuss payment schedules, discounts, bundled services, or other areas where there may be flexibility.
• Scope and deliverables: Walk through what’s included in the proposed scope of work, what would require additional fees, and how changes will be handled if project requirements evolve.
• Timelines and milestones: Confirm key deadlines, project milestones, and any dependencies that could affect the schedule. Discuss how delays, revisions, or scope changes will be managed.
• Contract terms. Review any renewal provisions, termination clauses, service expectations, and any performance metrics that will be used to measure success.
• Communication and collaboration. Establish a primary point of contact, preferred communication methods, and a process for addressing changes or issues as the project progresses.

After negotiations, document the changes in writing so both parties are working from the same expectations.

How to communicate your vendor selection professionally

Once you make your decision, notify your selected vendor first, followed by the remaining respondents. Keep your message concise, and avoid language that could create confusion around whether the decision is final.

If appropriate, you may provide a brief explanation for your decision, but avoid overexplaining or comparing vendors directly. Common reasons a proposal may be declined include:

• The proposal didn’t meet the RFP requirements or submission guidelines.
• The pricing exceeded the available budget.
• Another vendor offered more relevant experience or capabilities.
• Another proposal was a better overall fit for the project’s needs.

Thank vendors for their interest and effort in preparing the proposal, and if you’re open to working with them in the future, let them know. Ending the process with transparency and courtesy can help preserve positive relationships and encourage qualified vendors to respond to future opportunities.
