PBM Procurement Is a Big Comparison Problem

PBM procurement is often described as a sourcing problem. Employers, brokers, consultants, and procurement teams need to find the right Pharmacy Benefit Manager, issue an RFP, collect responses, compare proposals, negotiate terms, and implement a new arrangement.

That description is accurate, but incomplete.

At its core, PBM procurement is a comparison problem.

Health plans, hospital systems, employer groups and their advisors are not simply asking, “Which PBMs exist?” They are asking much harder questions:

Which PBM can support our population?
Which pricing model is actually better?
Which rebate arrangement is more transparent?
Which network design fits our members, patients, and rural challenges?
Which clinical programs are real, measurable, and relevant?
Which guarantees matter?
Which implementation timeline is realistic?
Which proposal creates the best long-term outcome for all parties?

Those questions are difficult to answer because PBM procurement still relies heavily on bespoke documents, custom spreadsheets, manual review, consultant interpretation, and long procurement cycles.

That model made sense when procurement lived in document exchanges, email threads, and custom RFP packages. It makes less sense in a market where buyers expect searchable information, structured comparison, controlled access, and faster decision making.

PBMs are under growing pressure from employers, policymakers, regulators, pharmacies, and patients. The FTC has continued to scrutinize major PBM practices, including pricing, reimbursement, and drug cost concerns. Federal and state policymakers have also shown sustained interest in PBM transparency and compensation reform.  

That pressure changes the procurement conversation.

It is no longer enough for PBM procurement to be thorough. It also needs to be faster, more understandable, more structured, and easier to compare.

That is where PfRs, or Proposals for Requestors, become important.

The Traditional PBM RFP Was Built for Customization, Not Speed

The traditional PBM RFP process is built around buyer-defined requirements. A plan sponsor, consultant, broker, or procurement team defines what it wants, sends a request to selected PBMs, collects responses, and evaluates the results.

For complex, highly customized arrangements, this approach can still make sense. Some employers have unique clinical needs, labor requirements, carve-out structures, network preferences, union considerations, specialty drug concerns, or legal constraints that require a custom process.

The problem is not that RFPs exist.

The problem is that too many PBM opportunities are forced into a bespoke RFP process even when the buyer’s needs could be evaluated through more standardized information.

A typical PBM procurement process may involve:

• Long RFP documents
• Customized vendor responses
• Large review teams
• Consultant-led analysis
• Legal review
• Clinical program review
• Network analysis
• Pricing and rebate modeling
• Spreadsheet comparisons
• Multiple finalist rounds
• Executive involvement
• Contract redlining
• Implementation planning

That amount of work may be justified for some large plan sponsors. But it creates real inefficiency across the market.

For employers, the process can feel slow and expensive. For PBMs, responding can require major labor investment with no guarantee of winning. For smaller PBMs, the cost of participation can make some opportunities difficult to justify. For smaller employer groups, the process may be too heavy to run efficiently.

This creates a market participation problem.

Large incumbents can absorb the cost of repeated RFP cycles more easily. Smaller PBMs may struggle to compete for attention. Smaller employer groups may struggle to access the depth of comparison that larger organizations receive. And even when multiple PBMs respond, the incumbent often has an advantage because switching costs, implementation risk, and familiarity all matter.

The result is a procurement system that may be comprehensive, but not always efficient.

Why PBM Proposals Are So Hard to Compare

PBM proposals are difficult to compare because the underlying business model is complex.

A PBM proposal is not a simple price quote. It may include administrative fees, rebate guarantees, discount guarantees, specialty pharmacy arrangements, mail service terms, retail network options, formulary structures, clinical programs, data reporting, audit rights, implementation timing, performance guarantees, and exclusions.

Even when two PBMs answer the same question, the answers may not be directly comparable.

One PBM may quote a stronger rebate guarantee but use a different formulary structure. Another may offer a lower administrative fee but weaker transparency. A third may have better specialty pharmacy capabilities but less attractive mail service terms. A fourth may offer better clinical programs, but only under certain utilization or eligibility assumptions.

PBM comparison becomes harder when proposals differ across:

• Rebate definitions
• Spread pricing arrangements
• Pass-through terms
• Specialty drug handling
• Pharmacy network requirements
• Mail order turnaround times
• Audit rights
• Data access
• Formulary exclusions
• Clinical program design
• Prior authorization workflows
• Implementation timelines
• Performance guarantees
• Definitions of savings
• Contract language

This is why PBM procurement often becomes spreadsheet-heavy. Buyers and advisors try to normalize information after responses arrive.

That is backwards.

The market should not wait until after proposals are submitted to begin standardizing data. Standardization should happen before comparison begins.

PBM Transparency Pressure

PBM transparency is no longer a niche concern.

Employers and plan fiduciaries are being asked to pay closer attention to how pharmacy benefits are managed, how compensation flows through the system, and how contracts align with participant interests. The Department of Labor has also proposed rules aimed at improving PBM fee and compensation disclosure for employer-sponsored health plans.  

This matters for procurement because transparency requirements are only useful if buyers can interpret what they receive.

More disclosure does not automatically create better decisions.

If PBM data arrives in inconsistent formats, buried in documents, spread across spreadsheets, or defined differently by each vendor, buyers still face a comparison problem. Transparency without structure can create more information, but not necessarily more clarity.

This is the gap modern procurement needs to solve.

The next generation of PBM procurement should help buyers understand differences faster. It should make key variables easier to compare. It should reduce avoidable manual work. It should help qualified PBMs package offerings in a way that buyers can evaluate without starting every process from scratch.

That requires structured procurement data.

What Are PfRs?

PfRs, or Proposals for Requestors, are a vendor initiated procurement method designed to make structured business offerings available to qualified buyers through a controlled online marketplace.

A PfR is created by a vendor using industry specific or product specific templates that include standardized questions. These templates define what information must be provided based on the expectations of a given industry, service category, or market segment.

In the PBM market, this could include structured information about pricing model, rebate approach, network options, clinical programs, specialty capabilities, mail service terms, implementation requirements, reporting, guarantees, and contracting expectations.

A PfR is not tailored to the needs of a specific buyer. It represents a vendor’s available inventory of products, services, capacity, or ready to deploy offerings.

That distinction matters.

Traditional RFPs begin with buyer-defined requirements. PfRs begin with vendor-defined availability. Instead of asking every vendor to build a custom response for every opportunity, a PfR allows qualified buyers to discover structured offerings that already exist.

PfRs are marketplace based. They are not public sales collateral. Access is restricted. PfRs can only be viewed after access requirements are met, including an executed agreement such as an NDA between organizations and acceptance by individuals with sufficient authority as defined by those organizations. Access is also limited by industry, product, and service relevance.

Once access is granted, qualified buyers can search, browse, filter, and compare available PfRs through marketplace tools.

This is a different procurement model.

It does not replace every RFP. It does not eliminate the need for negotiation. It does not remove legal, clinical, financial, or operational review.

But it can reduce the amount of unnecessary work required to discover and compare PBM options.

Why PfRs Fit the PBM Market

The PBM market is a strong fit for PfRs because many procurement questions are recurring.

Every employer group is different, but many PBM evaluations ask similar questions:

• What pricing model is available?
• Are rebates passed through?
• How are rebates defined?
• Is spread pricing used?
• What retail networks are supported?
• What specialty pharmacy options exist?
• What mail service terms apply?
• What clinical programs are included?
• What reporting is available?
• What guarantees are offered?
• What implementation timeline is realistic?
• What plan sizes are a good fit?
• What industries or employer types are best supported?
• What carve-out or integration options exist?

These questions do not need to be reinvented for every buyer.

They need to be answered in a structured way.

PfRs create a way for PBMs to package offerings using standardized templates, then make those offerings discoverable to qualified buyers. This helps shift PBM procurement from a document-first process to a marketplace-first process.

That shift matters because the traditional process creates friction on both sides.

For buyers, PfRs can make discovery faster. Instead of building an RFP just to learn what is available, buyers can review structured offerings after access requirements are met.

For PBMs, PfRs can reduce repetitive response work. Instead of rebuilding similar responses across many opportunities, PBMs can maintain structured offerings that reflect real availability.

For consultants and brokers, PfRs can create a more efficient starting point for comparison. Instead of spending excessive time normalizing inconsistent responses, advisors can begin with more standardized data.

For smaller employer groups, PfRs can create access to a more understandable procurement workflow.

For smaller PBMs, PfRs can create a better way to be found based on fit, not just brand recognition.

The Incumbent Advantage Problem

PBM procurement often favors incumbents.

That does not mean incumbents always win unfairly. In many cases, the incumbent may be the right choice. Staying with an existing PBM can reduce implementation risk, avoid disruption, preserve known workflows, and limit operational burden.

But incumbent advantage becomes a problem when the procurement process itself makes alternatives too difficult to evaluate.

If switching requires months of work, complex modeling, legal review, executive attention, and operational disruption, buyers may stay with an incumbent even when better-fit options exist.

This is especially important in a market where buyers are under pressure to evaluate costs, transparency, pharmacy access, and member outcomes more carefully.

A modern PBM procurement workflow should make it easier to understand available alternatives before a buyer commits to a full RFP cycle.

PfRs can help by allowing qualified buyers to compare structured PBM offerings earlier in the process. That does not force a switch. It simply improves visibility.

Better visibility creates better decisions.

Why AI Cannot Fix PBM Procurement Without Structured Data

AI is often discussed as if it can automatically solve procurement complexity.

That is unrealistic.

AI can summarize documents, extract key points, assist with analysis, and help identify patterns. But AI is only as useful as the information structure around it.

Traditional PBM RFP responses are difficult for AI to compare because they often contain inconsistent formats, different definitions, custom assumptions, and non-standard terminology. One vendor’s “pass-through” model may not mean exactly what another vendor means. One rebate guarantee may include different exclusions. One network comparison may depend on different claims assumptions.

AI can help, but it cannot magically create clean comparisons from messy inputs without risk.

Structured procurement data changes the equation.

When PBM offerings are submitted through standardized templates, comparison becomes more reliable. AI agents can analyze defined fields, identify missing information, flag differences, summarize tradeoffs, and help buyers understand which offerings may fit their needs.

This is where AI assisted procurement becomes practical.

Not because AI replaces expert judgment.

Because structured data gives AI something dependable to evaluate.

In PBM procurement, AI should support:

• Faster initial matching
• Side by side comparison
• Gap identification
• Pricing model review
• Rebate structure summaries
• Network comparison support
• Clinical program categorization
• Implementation readiness review
• Risk flagging
• Procurement dashboard insights

AI should not replace consultants, brokers, legal teams, pharmacy experts, or fiduciary review.

The best use of AI in PBM procurement is not to make the final decision. It is to reduce the manual burden required to reach a better-informed decision.

Why Side by Side PBM Comparison Matters

Most PBM procurement work eventually becomes a comparison exercise.

The problem is that comparison often happens too late and with too much manual effort.

A better workflow would allow buyers to compare PBM offerings across key categories earlier, including:

• Pricing structure
• Rebate approach
• Specialty pharmacy model
• Retail network options
• Mail service performance
• Clinical programs
• Reporting capabilities
• Transparency commitments
• Audit rights
• Implementation timing
• Contracting requirements
• Employer group fit

This does not mean every PBM can be reduced to a simple score.

PBM selection is too important for that.

But structured comparison can help buyers and advisors focus attention where it belongs. Instead of spending hours finding the differences, teams can spend more time interpreting the differences.

That is a better use of executive, legal, clinical, procurement, and consultant time.

PfRs and the Future of PBM Procurement

Modern procurement workflows should function more like searchable, structured internet marketplaces than bespoke document exchanges.

That does not mean procurement becomes casual. PBM procurement still requires confidentiality, compliance, careful evaluation, expert review, and disciplined contracting.

But the workflow can become more efficient.

In a PfR marketplace, qualified buyers can discover structured PBM offerings after access requirements are met. PBMs can present available offerings using standardized templates. Buyers can filter based on business context. Comparison tools can help identify relevant differences. AI can assist with structured review. Teams can move from discovery to discussion faster.

This is not a small improvement.

It changes the sequence of procurement.

Traditional RFP process:

1. Buyer defines requirements
2. Buyer invites vendors
3. Vendors create custom responses
4. Buyer collects documents
5. Buyer normalizes information
6. Buyer compares proposals
7. Buyer selects finalists
8. Buyer negotiates

PfR marketplace process:

1. Vendor creates structured offering
2. Access requirements are met
3. Qualified buyer discovers available offerings
4. Buyer compares standardized information
5. Buyer identifies strong-fit options
6. Buyer moves into discussion and contracting

The difference is speed and structure.

Instead of forcing every opportunity to begin with a custom solicitation, PfRs allow qualified buyers to discover what is already available.

Where Traditional PBM RFPs Still Make Sense

A credible procurement modernization strategy should be honest about where traditional RFPs still belong.

Some PBM arrangements are complex enough to require a full buyer initiated process. Large employers, coalitions, public sector entities, unions, and highly customized plan sponsors may need extensive custom requirements.

Traditional RFPs may still be appropriate when:

• The buyer has highly specific plan design requirements
• Multiple stakeholder groups must formally participate
• Public procurement rules require a specific solicitation format
• The arrangement involves unusual legal or operational constraints
• Custom clinical programs need to be developed
• The buyer requires a formal scoring process
• The contract is too complex for a standardized starting point

PfRs do not need to eliminate RFPs to be valuable.

They are valuable because not every PBM opportunity should require the same level of custom procurement effort.

The market needs more than one procurement pathway.

RFPs, RFIs, RFQs, and PfRs can each serve different needs. The mistake is treating the traditional RFP as the default for situations where structured marketplace discovery would be faster, cheaper, and easier to compare.

What PBMs Gain From Structured PfRs

PBMs often carry a heavy burden in traditional procurement.

Responding to RFPs can require sales, finance, clinical, legal, network, account management, operations, implementation, and executive input. When the PBM loses, much of that work produces no revenue.

That burden matters.

It can affect which opportunities PBMs pursue. It can make smaller opportunities less attractive. It can favor large buyers that justify the response investment. It can reduce market participation.

PfRs offer PBMs a more scalable way to package offerings.

A PBM can define available offerings, complete structured templates, control access, and make those offerings discoverable to qualified buyers. This does not remove the need for follow-up discussion. It does reduce repetitive early-stage response work.

For PBMs, structured PfRs can support:

• More efficient market exposure
• Better qualification of interested buyers
• Reduced repetitive proposal work
• Clearer packaging of available offerings
• More consistent presentation of pricing and capabilities
• Faster movement from discovery to discussion
• Better visibility for specialized or smaller PBMs

This is especially important as PBMs face increased pressure to explain pricing, rebates, transparency, network strategy, and value.

A PBM that can present structured, comparable information clearly may be better positioned than one that relies entirely on long-form documents and custom response cycles.

What Employer Groups Gain From PfRs

Employer groups need clarity.

Many employers want to understand whether their PBM arrangement is competitive, transparent, and aligned with their workforce needs. But not every employer has the internal team, budget, or timeline to run a heavy PBM procurement process.

PfRs can give employer groups a more accessible way to begin evaluation.

A buyer may not be ready to launch a full RFP. But they may be ready to explore available PBM options, compare structured offerings, and understand whether alternatives are worth deeper review.

That earlier visibility can improve decision making.

Employer groups can use structured PfR comparison to identify:

• Which PBMs serve similar group sizes
• Which pricing models are available
• Which rebate structures are easier to understand
• Which network options may fit their population
• Which clinical programs are included
• Which implementation timelines are realistic
• Which offerings deserve a deeper conversation

This supports a more informed procurement process without requiring every buyer to start with a blank document.

What Consultants and Brokers Gain From PfRs

Consultants and brokers play a critical role in PBM procurement. They help employers understand market options, evaluate proposals, negotiate terms, and manage risk.

PfRs do not remove that role.

They can make it more efficient.

When structured PBM offerings are available in a controlled marketplace, consultants and brokers can spend less time gathering basic information and more time interpreting fit, risk, tradeoffs, and strategy.

This is where expertise becomes more valuable, not less.

A structured marketplace can help advisors:

• Identify relevant PBM options earlier
• Compare standardized fields more efficiently
• Reduce manual normalization work
• Focus analysis on meaningful differences
• Support smaller employer groups more efficiently
• Use AI assisted tools with cleaner procurement data
• Prepare stronger recommendations

In a more transparent PBM market, advisors will be expected to help clients interpret more information. Structured procurement data can make that work more disciplined and scalable.

The Bigger Shift: From Documents to Data

The future of PBM procurement is not just faster RFPs.

It is a shift from documents to data.

Documents are useful for explanation, legal terms, narrative detail, and formal records. But documents are a poor foundation for scalable comparison.

Data is different.

Structured procurement data can be searched, filtered, compared, scored, summarized, and analyzed. It can power dashboards. It can support AI review. It can help buyers identify differences faster. It can reduce duplicate work for vendors.

This is the real reason PfRs matter.

A PfR is not just a different kind of proposal. It is a way to make procurement information structured from the beginning.

Once PBM procurement data becomes structured, the workflow can improve across the entire buying journey:

• Discovery becomes searchable
• Access becomes controlled
• Comparison becomes faster
• AI assistance becomes more reliable
• Dashboards become useful
• Advisors can focus on interpretation
• Buyers can make decisions with more confidence
• Vendors can present offerings more efficiently

That is procurement modernization in practical terms.

PBM Procurement Needs a Better Starting Point

PBM procurement will always require expertise.

The stakes are too high for oversimplified buying. Prescription drug benefits affect cost, access, member experience, adherence, pharmacy relationships, specialty drug strategy, and employer financial performance.

But expertise should not be wasted on avoidable administrative friction.

The current PBM procurement model often asks buyers and vendors to recreate the same early-stage information exchange again and again. That creates delay, cost, and confusion.

PfRs create a better starting point.

They allow PBMs to present structured offerings before a buyer launches a custom process. They allow qualified buyers to discover and compare available options in a controlled marketplace. They create the data foundation needed for AI assisted review and dashboard based comparison.

The PBM market is moving toward greater transparency, faster evaluation, and more disciplined comparison.

Procurement workflows need to catch up.

PfRs are one way to get there.
