Fractional vs Full-Time Commercial Director: Which Is Right for You?

A fractional Commercial Director gives a business senior revenue leadership for one or two days a week, on a retained basis, at a fraction of the cost of a full-time appointment. Whether that is the right answer depends less on budget than on the nature of the commercial problem you are trying to solve: does it need someone present every day, running a team and holding customer relationships, or does it need periodic, experienced judgement on pricing, margin and commercial structure?

This guide covers what a Commercial Director actually owns, how the group-level version of the role differs, what “fractional” means in practice, and how to choose between fractional, interim and full-time. It also sets out where fractional works well, where it predictably fails, how to structure the engagement and what to think about on cost and employment status. It is written by a firm that places all three models through its Commercial Director recruitment practice across the UK, so the aim is to help you pick the model that fits rather than to push one of them.

What does a Commercial Director do?

A Commercial Director owns how the business makes money. That is broader than sales and narrower than general management: it covers pricing, margin, commercial terms, channel and partner strategy, bid and contract governance, and usually the sales function itself. In many businesses it also takes in key account management, commercial forecasting and the relationship between what the business sells and what it can profitably deliver.

The distinction that matters is between revenue and profitable revenue. A Sales Director is measured on top line. A Commercial Director is measured on what falls through to margin — which means they will decline business a Sales Director would take, and will spend as much time on pricing discipline and contract terms as on winning new customers. They are the person who asks whether a large new contract is actually worth having once the payment terms, service levels and cost to serve are taken into account.

In most UK businesses the role reports to the Managing Director or CEO and sits alongside the Finance and Operations Directors. In practice the strongest Commercial Directors work unusually closely with the Finance Director, because margin analysis is where most of the value in the role is found. If you are writing the brief now, it is worth setting out the responsibilities, reporting lines and decision rights in writing before deciding which model fits, because the answer often becomes obvious once the role is on paper.

What does a Group Commercial Director do?

A Group Commercial Director holds the same remit across multiple operating businesses, and the job changes character as a result. Three things distinguish it.

• Consistency over control. They rarely run sales teams directly. Instead they set the pricing framework, approval thresholds and commercial standards that each subsidiary operates within, and intervene where a business unit is discounting its way to a bad year.
• Cross-selling and group scale. The commercial case for a group structure usually rests on selling more than one business’s products to the same customer. Making that actually happen — against the natural resistance of subsidiary MDs protecting their own numbers — is often the central task.
• Procurement and supplier terms. In many groups the role covers the buy side as well as the sell side, consolidating spend across businesses to improve terms.

The role demands influence without direct authority, which is a materially different skill from running a single commercial function. Candidates who have only operated in one business often struggle with it, and it is worth testing specifically at interview. Ask for examples of changing a pricing or commercial policy in a business unit they did not manage, and what happened when the local MD pushed back.

The group version of the role is also where the fractional question gets interesting. A group with several smaller subsidiaries may not be able to justify a full-time Commercial Director in any one of them, but can justify one at group level — or a fractional appointment that sets the framework across all of them while each business keeps its own sales lead.

What is a fractional director?

A fractional director is an experienced executive who works for several businesses concurrently, giving each a defined slice of their time — commonly one or two days a week — on an ongoing basis. They are not a consultant producing recommendations; they hold the role, sit on the leadership team and are accountable for outcomes within their remit. The model is now well established across the senior team, and our fractional C-suite practice covers finance, operations, marketing and technology as well as commercial roles.

The distinction from interim matters. An interim works full-time for a fixed period to resolve a defined situation. A fractional works part-time indefinitely because the business needs the capability continuously but not continuously present. Confusing the two leads businesses to pay interim day rates for what is really a fractional requirement, or to hire a fractional for a crisis that needs someone in the building every day. Where the answer is a part-time but ongoing role, our part-time Commercial Director recruitment service handles exactly that brief.

On the legal position: “fractional director” is a commercial description, not a statutory office. Under section 250 of the Companies Act 2006, “director” includes any person occupying the position of director, by whatever name called, and formal appointments are filed at Companies House. Most fractional Commercial Director appointments do not involve statutory directorship, which keeps things simple. Where they do — or where the individual in practice acts as a board director — they carry the full duties that come with the office, and both sides should be clear about that from the start.

Fractional, interim or full-time?

The three models answer different questions. The table below sets out how they typically compare; individual engagements vary, so treat it as a starting point for the conversation rather than a rule.

	Fractional	Interim	Full-time
Time given	Usually 1–2 days a week	Full-time	Full-time
Duration	Ongoing, often years	Fixed term, typically months	Open-ended
Best for	Judgement and structure, not daily presence	A defined problem with an end date	Leading a team day to day
Team leadership	Limited — coaches rather than manages	Full for the period	Full
Speed to start	Quick — no long notice period	Quickest — interims are usually between assignments	Slowest — search plus the candidate’s notice period
Relative cost	Lowest	Highest per day	Highest per year

A useful way to frame the decision is to ask three questions in order. Is there a deadline or a crisis? If so, look first at an interim Commercial Director, who can be in post quickly and work full-time until the situation is resolved. If not, does the role involve leading a sizeable team or owning senior customer relationships day to day? If so, the answer is almost always full-time. If neither applies, and what you need is experienced judgement on pricing, margin and commercial structure, fractional is likely to give you more capability for your money than any other option.

When fractional is the right answer

Four conditions point clearly toward a fractional Commercial Director.

• The problem is structural, not operational. Pricing is inconsistent, discounting is uncontrolled, nobody knows which customers are actually profitable. That work is analytical and periodic, and it does not require someone in the building five days a week.
• You have a capable sales manager but no commercial strategy. The team can sell; what is missing is the framework telling them what to sell, to whom and at what price. A fractional appointment supplies the framework and coaches the incumbent rather than displacing them.
• The business has outgrown the founder as commercial lead but cannot yet justify a full-time director. In smaller businesses the founder usually is the commercial function. In larger ones the role generally needs to be full-time. The stage in between — where the founder’s time is better spent elsewhere but the workload does not fill five days — is where fractional does its best work.
• You are preparing for investment or sale. Buyers and sponsors scrutinise revenue quality, customer concentration and margin sustainability. Getting that in order is a defined, expert task and one of the clearest fractional use cases, particularly in businesses heading toward a private equity process.

The common thread is that the business needs someone to decide what the commercial work should be, not someone to do all of it. A fractional director with a long track record will often see in weeks what a less experienced full-time hire would take a year to find, because they have seen the same pattern of margin leakage, unprofitable customers and unpriced extras in other businesses.

A pattern we see often in owner-managed businesses is revenue growing while margin quietly erodes, usually because discounting has become the default answer to competitive pressure and nobody owns the pricing decision. That is a commercial leadership gap rather than a sales problem, and it rarely needs a full-time appointment to fix.

When it is the wrong answer

Fractional fails predictably in three situations, and it is worth being honest about them.

• A large sales team needing daily leadership. Managing a sizeable sales team requires presence — pipeline reviews, coaching, escalations, hiring and performance management. One or two days a week will not cover it, and the team will notice.
• The role is customer-facing at the top. If your largest accounts expect a senior relationship, a part-time director cannot maintain it. Key clients read reduced availability as reduced importance.
• The business is in commercial crisis. Losing major customers or facing a collapse in margin needs full-time attention immediately. That is an interim requirement, not a fractional one.

There is a fourth, softer failure mode: the business that hires a fractional director and then does not give them the authority to act. If pricing decisions still need the founder’s sign-off on every deal, or the sales team is told to carry on as before, the fractional director becomes an expensive adviser. Before appointing, be clear what decisions they will own and who in the business will carry out the work between their days.

If the honest conclusion is that you need a full-time appointment, our guide on how to hire a Commercial Director walks through the brief, the search and the selection process.

What it costs

A fractional Commercial Director is engaged on a monthly retainer or a day rate, with no pension, holiday, notice period, employer National Insurance or severance exposure attached. Against a full-time package the saving is substantial, but the more useful comparison is against the cost of the commercial problem. A business that is discounting more than it needs to, or carrying customers that lose money once cost to serve is counted, is often losing more each quarter than the appointment costs.

Rates depend on the scope of the role, the sector, the individual’s track record and whether the engagement includes a board seat or investor-facing work. Rather than rely on a headline figure, agree the number of days, the outputs expected in the first few months and how performance will be reviewed. That makes it far easier to judge whether the engagement is earning its fee.

Where the individual works through their own limited company, the off-payroll working rules (IR35) need to be considered. HMRC’s off-payroll working guidance sets out the overall position. Under the rules, public sector clients and medium or large private sector clients must decide the worker’s employment status and issue a status determination statement with their reasons; for small private sector clients, the worker’s own company makes that decision instead. HMRC’s guidance on off-payroll working for clients explains the size tests and what a client must do, and its Check employment status for tax (CEST) tool can help with the assessment. Settle the position before the engagement starts, not after the first invoice.

Commercial Director, Sales Director or CMO?

These three are frequently conflated, and appointing the wrong one is expensive.

A Sales Director owns the sales team and the top line. Appoint one when you have a defined proposition and market and need more of it sold. Our Sales Director recruitment work covers both permanent and part-time appointments.

A Commercial Director owns profitable revenue — pricing, margin, terms and usually sales as well. Appoint one when the issue is the quality of revenue rather than the quantity. In larger or more complex businesses the same remit may sit with a Chief Commercial Officer on the executive committee, with Commercial Directors reporting into them by division or region.

A CMO or Marketing Director owns demand generation, brand and positioning. Appoint one when the problem is that not enough of the right people know who you are. If you are weighing a fractional CMO against a full-time Marketing Director, that is a different comparison from this one, although the same logic about presence versus judgement applies.

Many growing businesses start with a fractional Commercial Director precisely because the role sits across these boundaries: they set the pricing and commercial framework, shape what the sales team is asked to sell, and give a clearer brief for any later sales or marketing hire.

Making a fractional appointment work

Fractional engagements succeed or fail on structure more than on the individual. The following points make the difference.

• Write a scope, not a job title. List the decisions the fractional director will own, the outputs expected in the first ninety days and the measures that will show progress — gross margin by customer or product, discount levels, win rates on target accounts.
• Protect the days. Fix the days in the diary and keep them for commercial work. A fractional director pulled into ad hoc meetings delivers little of the value the arrangement was meant to buy.
• Give them a counterpart. Someone in the business — a sales manager, the Finance Director or a commercial analyst — needs to carry out the work between their days. Without that, plans stall.
• Give them the data. Margin work depends on clean customer and product profitability data. Make sure finance can provide it, or make building it part of the first phase.
• Agree how it ends or grows. Set a review point, typically at six months, and agree in advance whether the role might scale up, convert to full-time or hand over to a permanent hire.

From fractional to full-time

A fractional Commercial Director is often the first step rather than the final answer. As the business grows, the pricing framework is in place and the sales team expands, the role may need someone present every day. The signs are usually clear: the fractional director is regularly working beyond the agreed days, key customers are asking for more senior contact, or the sales team needs daily leadership that the current manager cannot provide.

At that point there are two routes. Some fractional directors are open to converting to a full-time role, which keeps continuity; many career fractionals prefer the portfolio model and would rather help recruit and hand over to a permanent successor. Either works, provided it was discussed at the start. A fractional director who has spent a year in the business is also well placed to help write the brief for the permanent hire, which tends to make the search sharper. Where the permanent role is pitched at executive committee level, our guide on how to hire a Chief Commercial Officer covers that step. When you are ready, our Commercial Director search team can run the permanent appointment alongside the outgoing fractional.

Frequently asked questions

What is a Commercial Director?

A senior executive accountable for how a business generates profitable revenue — pricing, margin, commercial terms, channel strategy and usually the sales function. They typically report to the Managing Director or CEO and sit on the senior leadership team.

What does a Group Commercial Director do?

They hold commercial responsibility across several operating businesses, setting pricing frameworks and approval thresholds group-wide, driving cross-selling between subsidiaries, and often consolidating procurement. The role relies on influence across business units rather than direct line management.

What is a fractional director?

An experienced executive who works for several businesses at once, giving each a set portion of their time — usually one or two days a week — on an ongoing basis. Unlike a consultant they hold the role and carry accountability for outcomes within it.

How many days a week does a fractional Commercial Director work?

Most commonly one or two days a week, sometimes a couple of days a month for a purely strategic remit. What matters more than the number is consistency and whether the days are protected for commercial work.

What is the difference between a Commercial Director and a Sales Director?

A Sales Director is measured on revenue; a Commercial Director is measured on profitable revenue. The Commercial Director owns pricing, margin and contract terms as well as sales, and will decline business a Sales Director would pursue.

Can a fractional Commercial Director become full-time?

Sometimes, and it is a sensible progression where the business grows into the requirement. Many career fractionals prefer the portfolio model, so agree at the outset whether conversion is a possibility and on what terms.
