RFP for Consulting Services: How to Buy Advice You Can Hold Someone To
An RFP for consulting services asks firms to price something you cannot inspect. A software build ships code you can test. A construction job ends in a building you can walk through.
Advisory work ends in a recommendation, and the buyer signs off on a deck. That gap is where consulting engagements go wrong. Five decisions close it, and each one belongs in the document rather than the contract talks that follow.
Key Takeaways
- Name the decision the work must enable. A topic invites a study. A decision invites an answer.
- Write acceptance criteria for advice, since a deck is a format rather than a deliverable.
- Ask who shows up. The partner who pitches is often not the person who does the work.
- Settle whether the advisor may bid on the work it recommends, and say so in the document.
- Keep the models, the data, and the notes. Capability should stay after the team leaves.
Advisory Work Breaks the Normal RFP
Three things make consulting different from other services buys.
The output resists inspection. You can test whether a report arrived. Judging whether the advice was any good takes months, and by then the team has moved on.
The people change. Firms field senior partners for the pitch and staff the work with juniors. That is not deception in most cases. It is how the model runs, and your document either addresses it or accepts it.
The advisor has an interest in what comes next. A firm recommending a big change programme may also sell the delivery of it. Federal rules treat that as a named risk. Private buyers face the same one with fewer safeguards.
For the discipline itself, see our overview of what business consulting covers. For the standard sections any solicitation needs, see our guide to how to write an RFP. This post covers what changes when the thing you buy is judgment.
The MERIT Framework for a Consulting RFP
At The Write Direction, we work consulting solicitations through five decisions: mandate, evidence, roles, independence, and terms. MERIT keeps the document focused on what a firm can price and a buyer can hold someone to.
M: Mandate. Name the Decision, Not the Topic
“Assess our supply chain” is a topic. Firms respond with a study.
“Give us the evidence to decide by June whether to merge three warehouses into one” is a decision. Firms respond with an answer, a method, and a timeline that ends when you can act.
Write three things into the mandate. The decision you face, with its deadline. The current numbers that frame it. The person who will make the call and the forum where it happens.
Say what you have tried and what you already believe. Buyers hide prior work in case it biases the advice. The effect is the opposite. Firms spend three weeks finding it again, on your money.
E: Evidence. What Done Looks Like for Advice
A deck is a format. Set out what has to be in it.
List deliverables with acceptance criteria beside each. A market assessment that names three options, sizes each, and states the assumptions behind the numbers gives you something to accept or reject. The same assessment with no test attached gives you a meeting.
Set checkpoints so problems surface early. A hypothesis memo at week two, a finding at the midpoint, and a draft before the final version keep both sides honest. Firms that resist checkpoints are telling you something.
State your own obligations too. Data access, interview scheduling, and the people who must be available. Consulting timelines slip on buyer-side delays more often than on consultant delays.
Carry the acceptance terms into the contract. Our comparison of RFP vs SOW covers that handoff.
R: Roles. Who Shows Up, and Who Directs Them
Ask for named people, their hours on your engagement, and their other commitments during your window. Then add a substitution clause. Replacements need your approval, and the replacement must match the seniority you priced.
Ask what share of the work each named person does. A partner listed at 5 percent is a reviewer. Pricing that charges partner rates across the whole job is worth a question.
The second half of this section gets skipped, and it carries real risk. Federal rules draw a line between buying a result and directing people. Those rules bind government buyers rather than private ones, and the reason to borrow them is that they are public, tested, and specific where commercial practice is vague.
Under FAR 37.104, an employer-employee relationship forms when the contract’s terms, or the way it runs day to day, put contractor staff under supervision and control that is close to continuous. Ordering a specific result, with the right to reject it, does not cross that line.
The same rule lists the warning signs: work performed on your site, your tools and equipment, services applied to your core function, comparable work done by your own staff, and a need expected to last beyond a year. An RFP that asks for three analysts for nine months has most of those signs. Buy an outcome instead, or accept that you are hiring staff and price the employment risk.
I: Independence. The Advisor and the Contract That Follows
The subpart of federal rules that covers this is titled Organizational and Consultant Conflicts of Interest, which tells you how common the problem is. FAR Subpart 9.5 says conflicts are more likely in contracts for management support, consulting and other professional services, and help with evaluations.
Two principles sit under it. Stop roles that might bias judgment, and stop unfair advantage in later competitions.
One rule matters most to a consulting buyer. A firm that prepares or helps prepare a work statement used to buy services in a competition may not then supply those services, with three narrow exceptions.
The worked example in the rules is plain. A firm designs a training curriculum, the agency puts that curriculum into its solicitation, and the firm may not win the contract to deliver the training.
Decide your position and publish it. You have three options: bar the advisor from the follow-on work, allow it and accept the bias risk, or allow it with safeguards such as an independent review of the recommendation.
The rules make the buyer state the conflict and the restraint in the solicitation, and cap that restraint at a fixed term ending on a stated date or event. Copy that structure.
Ask bidders to disclose current and recent work for your competitors, your suppliers, and any firm that would benefit from a given recommendation.
T: Terms. Fees, Work Product, and What You Keep
Three fee models cover most consulting buys, and each rewards different behaviour.
- Fixed fee suits a defined question with a defined end. It puts scope risk on the firm and makes scope creep a negotiation.
- Time and materials with a ceiling suits open-ended discovery. It needs someone on your side reviewing progress weekly.
- Outcome-linked fees suit measurable results, and they need a metric both sides trust before signing.
Cap expenses as a share of fees and state your travel policy. On a long engagement, expenses can run to a fifth of the bill.
Settle work product. You should own the report, the underlying models, the cleaned data, and the interview notes. Firms keep their own methods and tools, which is fair. Name what stays yours and what stays theirs.
Add a knowledge transfer deliverable. A working session with your team, documented models, and a short handover memo turn a report into capability. Without it, the insight leaves with the team.
A Consulting RFP Section Order That Works
- Background and the decision. Two paragraphs on the business, then the call you have to make.
- Baseline. The numbers that frame the decision.
- Scope. Questions to answer, with what sits outside.
- Deliverables and acceptance. Artifacts, criteria, checkpoints.
- Buyer obligations. Data, access, people, response times.
- Team. Named staff, hours, substitution rules.
- Independence. Disclosures and your follow-on position.
- Fees. Model, ceiling, expense cap, payment milestones.
- Evaluation. Criteria and weights, published.
- Terms. Work product, confidentiality, knowledge transfer, exit.
Professional services buys in regulated fields follow a close cousin of this order. Our investment management RFP guide covers that version, where independence and named personnel carry even more weight.
Evaluating Consulting Proposals
Written proposals reward proposal departments. Design around that.
Cap the written response and put weight on an oral session with the proposed team. Give finalists a real problem from your business and 30 minutes to work it in front of you. That tells you more than any case study.
Call references, and ask about the named partner rather than the firm. Ask whether that person stayed past the first month. Ask what the firm did when a finding was unwelcome, and whether the final invoice matched the estimate.
For weighting and scorecard mechanics, see our guide to evaluation criteria and scorecards.
Pre-Issue Checklist
Run these seven checks on your draft. They take an hour and catch most of what goes wrong later.
- The decision named, with a deadline and a decision owner.
- Deliverables listed with acceptance criteria beside each.
- Interim checkpoints scheduled, not just a final report.
- Buyer obligations stated, including data and access.
- Named personnel required, with substitution rules.
- Independence position published, with any restraint given a fixed end.
- Work product ownership and knowledge transfer written into the terms.
Timeline pressure is the usual reason these get skipped. Our guide to how long each RFP phase takes helps you work backward from the decision date.
When to Write This Yourself, and When to Bring in Help
Plenty of consulting briefs need no outside help. Write it yourself when the decision is clear, the budget sits under six figures, one person owns the outcome, and you have run a similar buy before.
Bring in help when one of these is true:
- The decision goes to a board or a public body, and the paper trail has to hold up.
- Three or more internal groups want different things from the same engagement.
- Regulated work, where independence and disclosure language carries legal weight.
- An incumbent is bidding, and the process has to look fair as well as be fair.
- The last engagement of this kind overran, and your team cannot point to the clause that should have caught it.
- Your side has not written acceptance criteria for advisory work before.
The test is exposure rather than size. A $60,000 engagement that sets a five-year direction deserves more document care than a $400,000 staffing buy.
From Our Client Work
Please have a look at our case studies here.
Clients bring The Write Direction a consulting brief that reads well and commits neither side. The fix is seldom more words. It is naming the decision, the evidence, and the people.
Frequently Asked Questions
What should an RFP for consulting services include?
An RFP for consulting services should carry the decision the work must enable and its deadline, baseline numbers, and the questions in scope and out.
Add deliverables with acceptance criteria, checkpoints, your own obligations for data and access, named staff with substitution rules, and independence disclosures. Close with the fee model, an expense cap, published evaluation criteria, and terms for work product and knowledge transfer.
How do you define deliverables for consulting work?
Pair each deliverable with a test. Instead of a market assessment, ask for an assessment that names three options, quantifies each against stated assumptions, and recommends one with the reasoning shown.
Add interim checkpoints such as a hypothesis memo and a draft, so gaps surface before the final version. A format alone gives you a meeting rather than a deliverable.
Should a consulting RFP be fixed fee or time and materials?
Fixed fee suits a defined question with a clear end, and it puts scope risk on the firm.
Time and materials with a ceiling suits open-ended discovery, and it needs weekly oversight on your side. Ask bidders to price both ways when the scope is uncertain. The gap between the two numbers shows how much risk each firm sees in your brief.
Can a consultant that writes your strategy bid on the implementation?
Only if you decide so in advance and say it in the document. Federal rules bar a contractor that helped write a work statement from supplying those services, with narrow exceptions.
The worked example bars a firm that designed a training curriculum from delivering the training. Your options are to bar the follow-on work, allow it, or allow it with independent review.
How many firms should receive an RFP for consulting services?
Three to five is the working range. Consulting proposals take real effort to write and to judge. A longer list lowers the quality of both.
Prequalify on sector experience and the availability of the people you want. A shortlist also leaves room for oral sessions, which tell you more about fit than any written response.
Buy the Decision, Not the Deck
An RFP for consulting services works when firms can price the same question and you can hold the winner to something. Name the decision.
Write acceptance criteria. Ask who shows up and who directs them. Settle independence before the recommendation arrives. Keep the models and the data when the team leaves.
At The Write Direction, our team writes procurement documents for buyers across the public and private sectors.
On a consulting brief we turn a topic into a decision, write acceptance criteria for advisory deliverables, draft the independence and work product clauses, and build the evaluation sheet your panel scores against. Most briefs take two working sessions and a draft.
Send us your current draft or your starting notes through our request for proposal assistance page, or email [email protected]. If the wider engagement needs shaping first, our consulting team can help with that instead.
