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 whether the commercial problem you are solving needs continuous presence or periodic judgement.

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 is written by a firm that places all three — Commercial Director recruitment across the UK.

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.

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.

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.

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 leverage. 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.

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 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.

On the legal position: “fractional director” is a commercial description, not a statutory office. The office of director is defined at section 250 of the Companies Act 2006 and arises from formal appointment and filing at Companies House. Most fractional appointments do not involve statutory directorship, which keeps things simple. Where they do, the individual carries the full duties that come with it.

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.

Revenue is between roughly £2m and £15m. Below that the founder is usually still the commercial leader. Above it the role generally needs to be full-time. In between 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.

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 fifteen salespeople requires presence — pipeline reviews, coaching, escalations. 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.

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 discounting two points more than it needs to is losing more each quarter than the appointment costs in a year.

Where the individual works through their own limited company, the off-payroll working rules apply and, for medium and large private-sector clients, the status determination is the client’s responsibility. HMRC’s off-payroll working guidance sets out the position; settle it before the engagement starts. Current benchmarks for permanent equivalents are in our directors’ salary guide.

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.

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.

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 — the marketing pages set it out properly, including the part-time CMO and interim CMO options.

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 two days a month for a purely strategic remit. What matters more than the number is consistency and whether the days are protected — a fractional director constantly pulled into ad hoc work delivers little of the value the arrangement was meant to buy.

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.
