Hiring a sales process redesign consultant: scope, fit and what you should get

A sales process redesign consultant is worth hiring when your stages exist but the process doesn't hold. Qualification varies by seller, forecasts are argued over, and deals move in the CRM without clear evidence. Bring one in when your own leaders lack the time to fix it, or need a neutral party to get sales, marketing and finance to agree. Don't hire one when the process is sound and the real gap is adoption or coaching.

This guide is for a sales director or CRO deciding whether to commission outside help to redesign the sales process. It covers when it's worth it and when it isn't, what the engagement should examine, what you should receive, what your team must provide, and how to judge a provider.

When a sales process redesign consultant is worth it, and when not

Merlin5's sales process work starts from one observation: "Many organisations have sales stages. Few have a sales process." When stages are only labels, the CRM records where a deal sits without showing what has been proven. Our guide to sales process stages explains what a stage should contain.

A consultant is usually worth it when:

• sellers and managers describe the same stage in different ways;

• the forecast is rebuilt by hand because the pipeline can't be trusted;

• you're planning a CRM project and need the process settled first;

• the sales, marketing and finance leaders disagree, and someone needs to run the decision neutrally;

• your leaders know what's wrong but can't spend the weeks needed to fix it while running the number.

It usually isn't worth it when:

• the process is documented, managers inspect deals against it, and the gap is that sellers don't follow it. That's an adoption and coaching problem. Our guide to rolling out a sales methodology covers how to make a method stick.

• the shortfall is too few opportunities rather than poor conversion. That points at demand generation and marketing alignment, not the process.

• you only need the existing process built into the CRM. Our guide to choosing a CRM implementation partner covers that decision.

What the engagement should examine first

A good redesign starts from how your customers buy and how deals really progress. It doesn't start from a standard stage template. That matters because B2B buying involves many people. Forrester's 2024 State of Business Buying study of more than 16,000 buyers found that, on average, 13 people are involved in a buying decision, and 89% of purchases involve two or more departments.

The diagnostic scope should include:

• Deal history. Won and lost deals over at least the last year, with time in each stage and where deals stalled. Our guide to stalled deals covers the signals worth looking for.

• Buyer evidence. How your customers decide, from win and loss reviews and from talking to sellers and, where possible, customers.

• The current stages. How each one is defined, what the CRM requires at each step, and how managers use them in reviews.

• The handoffs. Marketing to sales, sales to delivery, and how renewals and growth are handled.

• The forecast. How it's built, and where it has been wrong.

The UK Government's service design guidance makes a similar point about mapping a journey: complicated journeys "often cut across organisational boundaries". A sales process that only maps the sales team's steps will miss where deals are lost between teams.

What you should get at the end

You should get a process people can use, written so the CRM can enforce it. On Merlin5's own page, the deliverables of a transformed sales process include:

• sales process design aligned to how your buyers buy;

• a stage architecture, with a purpose, evidence requirements and governance rules for each stage;

• an entry and exit criteria framework;

• qualification framework design;

• customer lifecycle design, from acquisition through retention and growth.

Ask for one more thing: CRM requirements written from the process. Every major CRM can enforce a defined process, but it has to be defined first.

• Microsoft Dynamics 365: business process flows can make a field required before a deal moves on, which Microsoft calls "stage-gating".

• HubSpot: a required property stops a record being updated until it's filled in.

• Salesforce: Trailhead tells admins to decide the stages that appear for reps with their sales operations manager.

The tools enforce whatever process you give them.

What a good output looks like:

• one page per stage that a new seller could follow;

• criteria based on what the buyer has done or confirmed, not on seller activity;

• a governance rhythm, such as who reviews what, and how often.

A large deck of principles with no stage definitions is a weak output.

What your team must provide

Redesign work goes at the pace your teams can agree. Merlin5's FAQ on this work says it takes two to three months on average. What sets the pace is agreeing definitions across teams that have been using their own. Plan for:

• A decision owner, usually the sales director or CRO, who can settle disputes quickly.

• Time from managers and experienced sellers for workshops and for testing the draft stages on live deals.

• Access to CRM data and to people in marketing, finance and delivery.

• A pilot group to try the new stages before they go wide.

If you can't provide these, delay the project. A redesign done without your managers is unlikely to produce a process they'll use.

Questions to ask a provider

1. How will you learn how our customers buy? A good answer names the evidence: deal history, win and loss reviews, and seller and customer conversations. It shouldn't be a framework they bring in unchanged.

2. Which methodology will you use? A good answer fits the methodology to your process, not the reverse. Merlin5's own page puts it simply: the methodology serves the process.

3. Who does the work? Look for people who have run sales teams and carried a number, not only facilitators.

4. How will you get sales, marketing and finance to agree? Ask how disputes are settled and who signs off each definition.

5. What will the CRM requirements look like? Ask to see an example, with personal details removed.

6. How will we know it's working? A good answer names measures such as stage conversion, forecast accuracy and time in stage, checked against today's baseline.

Red flags:

• a fixed stage template proposed before they've seen your deals;

• no plan to involve your managers;

• outcome claims with no method or timeframe;

• deliverables that stop at the design, with no path into the CRM or the management rhythm.

What this looked like at Source 1 Solutions

Source 1 Solutions' president described Merlin5's work as including "a complete sales process redesign", alongside sales standards, playbooks and leadership enablement. The Source 1 case study sets out how the work started with diagnostics. It then designed a Sales Operating System built on Customer-Centric Selling and MEDDPICC, with qualification standards, forecasting disciplines and pipeline governance. Merlin5's founding partners include leaders who have run large sales organisations, including Hewlett Packard Enterprise's. If you're still weighing up the wider CRM project, our guide to CRM transformation sets out the order of the work.

Where to start

1. Pick ten recent deals, five won and five lost, and ask three managers which stage each reached and why.

2. If the answers differ, write down where they differ. That's your scope.

3. Decide who owns the final definitions before you speak to any provider.

Frequently asked questions

How long does a sales process redesign take?

It depends on the size of the organisation, the state of the data and how quickly teams agree definitions. Merlin5's own page gives two to three months on average for its process and CRM work. Agreeing definitions usually takes longer than the design.

Should we redesign the process ourselves?

You can, if a leader has the time and the authority to settle disagreements across sales, marketing and finance. Outside help earns its fee when those conditions aren't there, or when you need an independent view before a CRM decision.

Do we need a new CRM afterwards?

Usually not. Most CRMs can enforce a well-defined process. Test what your current platform can do once it's asked to enforce the new stages, before you consider replacing it.

How do we keep the new process from fading?

Build it into the CRM, into pipeline and forecast reviews, and into how new sellers are onboarded. A process that managers don't inspect each week will drift back to old habits.
