How Do I Build a Sales Function From Scratch?

Most founder-led businesses do not lack sales activity. They lack a sales function — a repeatable, documented, measurable way of turning interest into revenue that does not require the founder to personally run every conversation. Those are different problems, and the second one is what usually stops a business scaling past the point where the founder is the only person who can close a deal.

Building a sales function from scratch is not primarily about hiring a salesperson. It is a sequencing exercise: define the process before you hire for it, get the numbers visible before you set targets against them, and only then bring in people or structure. Get that order wrong and even a genuinely good hire will fail, because there is nothing for them to plug into.

Why does hiring a salesperson first usually fail?

It is the most common shortcut, and the most common source of an expensive, disappointing first hire. A founder who has been winning business personally for years has an enormous amount of undocumented knowledge — which questions actually qualify a prospect, what objections come up and how they get answered, what a good customer looks like versus a bad one. A new salesperson has none of that. Without it written down somewhere, they spend their first six months reconstructing it slowly through trial and error, at your expense, while the founder watches and concludes the hire was not good enough.

The fix is not to avoid hiring. It is to write the process down before the hire arrives, so day one starts with something to follow rather than a blank page and a target.

What does the founder's existing process actually look like?

Before anything else, sit down and reconstruct how deals have actually been won over the last year, honestly rather than aspirationally. Where did the enquiry come from? What did you ask before quoting? What made some prospects convert and others go quiet? Most founders discover they already have a process — it has simply never been written down, and it is not consistent from deal to deal because it lives entirely in their head and adapts on the fly.

• Where genuine enquiries actually come from, ranked by volume and quality
• The questions you ask early to work out if a prospect is real
• What information you need before you will quote
• The objections that come up most often, and how you actually answer them
• What separates a customer you are glad you won from one you regret

How simple should the first version of the process be?

Deliberately simple. A five-stage pipeline — enquiry, qualified, quoted, negotiating, won or lost — is enough for most SMEs starting from nothing. The temptation is to build something sophisticated with automated scoring and multiple sub-stages before a single deal has moved through it. Resist that. A process nobody follows because it is too complicated is worse than no process, because it creates the appearance of structure without the substance.

What should you measure from day one?

Five numbers, tracked honestly even if the first month's data is rough: how many enquiries came in, how many were qualified as real, how many were quoted, how many were won, and how long the whole cycle took. You do not need software to start this — a spreadsheet updated weekly is entirely adequate at this stage. What matters is that the numbers exist and are looked at regularly, not that the tooling is impressive.

When is the business genuinely ready for a first sales hire?

Readiness is less about revenue size and more about whether there is enough proven, repeatable enquiry volume to give a new hire something real to work. Hiring into a business with barely any inbound interest sets someone up to fail through no fault of their own — there is nothing to sell into. A reasonable test is whether the founder, applying the documented process, is currently turning away or delaying opportunities purely through lack of time. That is the signal capacity is genuinely the constraint, not process or demand.

What should the first hire actually be responsible for?

Be specific rather than hiring a generic "salesperson" and hoping they work out what that means. Decide whether the priority is following up existing enquiries more consistently than the founder currently manages, opening new conversations that nobody has time to start, or both. A first hire asked to do everything the founder currently does, with none of the founder's relationships, knowledge or authority, is being set an unfair task.

What management rhythm needs to exist before or alongside the hire?

A first salesperson without any regular review structure tends to drift, not through laziness but because nobody is checking in on activity, only eventually noticing results. A short weekly conversation — what moved in the pipeline, what is stuck, what help is needed — costs thirty minutes and prevents six months of quiet underperformance going unnoticed. This does not need to be formal or software-driven at first; it needs to happen consistently.

What mistakes do founders most commonly make at this stage?

• Hiring a salesperson before writing anything down, then blaming the hire when they struggle to reconstruct the process alone
• Building an elaborate CRM before a single deal has been tracked in a spreadsheet
• Setting a revenue target for a new hire before there is proven enquiry volume to support it
• Continuing to personally handle every large or interesting deal, leaving the new hire only the leftovers
• Reviewing performance only against revenue, with no visibility of the activity that should have produced it

How does this evolve once the first hire is established?

Once one person is reliably following the process and the numbers are trusted, the next step is usually deciding whether growth needs more of the same role, a different kind of role such as business development focused purely on opening new conversations, or senior oversight to manage a small team properly rather than the founder continuing to manage it informally. That decision is easier to make well once real data exists, rather than guessed at from the outset.

Do you need outside help to build this, or can it be done internally?

A lot of this — documenting the existing process, setting up a simple pipeline, defining the first hire's role — can genuinely be done internally by a founder willing to spend a few focused days on it rather than fitting it around everything else. Outside help earns its place when the founder cannot find the time to do this properly alongside running the business, when a first hire has already failed and nobody is sure why, or when the business needs someone experienced to manage the new hire day to day rather than adding that to the founder's own workload. That is closer to what fractional commercial leadership is for than a one-off diagnostic.

If you are not yet sure which of these problems you actually have, the Sales Help for Founders & Business Owners hub sets out the different starting points depending on whether the gap is process, people or management capacity.
