Customer work has outgrown the way it is run. 01 Customers are slow to reach value Deals close, then onboarding drags and the first real result takes too long.
02 You are still on the escalation path Support questions and customer issues keep landing back on the founder.
03 What worked informally is breaking More customers or more complex implementations have made the work inconsistent.
04 Renewal risk shows up too late Health, ownership and renewal risk only become visible when it is hard to act.

The work finds what is holding customer work back, installs a practical fix, and leaves your team with a structure it can keep running. FAQ
What is a fractional Head of Customer Success? A fractional Head of Customer Success is a senior customer success leader who works with your company part time, usually one to three days a week, rather than as a full-time employee. They own the post-sales function: onboarding, time to value, support handoffs, renewals, expansion, and turning customer insight into priorities for product and sales. For a small SaaS company, it means senior CS leadership before a full-time executive salary is justified.
When should a SaaS company hire a fractional Head of Customer Success? A SaaS company should hire a fractional Head of Customer Success when customer growth has outgrown the founder-led, ad hoc way of looking after customers, but does not yet justify a full-time senior hire. Typical signals:
Customers onboard inconsistently or take too long to reach value. Support and escalations are consuming the founder or sales team. Renewal risk and expansion opportunities are not visible early enough. There are customer-facing people, but no clear post-sales owner, process or measures. You need to prove the value of a CS function before committing to a permanent Head of CS. Should our first customer success hire be a CSM or a Head of Customer Success? Hire a CSM first if you already know how onboarding, renewals and escalations should run and simply need more capacity. Put a senior leader in first if nobody has defined how customer work should run, because a junior CSM will inherit the inconsistency rather than fix it.
A fractional Head of Customer Success is a common middle path for small SaaS companies: they design the system part time, then define the role and success measures for the first CSM hire.
How much does a fractional Head of Customer Success cost? A fractional Head of Customer Success is usually paid as a monthly retainer based on days per week, so the cost is a fraction of a full-time senior salary and stops when the need does.
With SuccessByCS, most companies start with the Post-Sales Reset, a half-day working session for a fixed fee of $500, billed in your local currency. You see the approach and leave with a clear view of what to fix first before committing to an ongoing engagement.
How many days a week does a fractional Head of CS work, and for how long? A fractional Head of Customer Success typically works one to three days a week. Engagements usually start with a 90-day block, long enough to diagnose the gaps, build the core system and embed it with the team, and continue only while there is clear value to add. Mentoring for new CS leaders runs as fortnightly sessions over three to six months.
What can a fractional Head of Customer Success achieve in the first 90 days? In the first 90 days, a fractional Head of Customer Success can:
Identify the biggest customer, onboarding and renewal risks. Map the post-sales journey and clarify ownership. Introduce simple measures for activation, health, support and renewals. Build essential playbooks and operating rhythms. Coach the team and embed the new ways of working. Show early progress and recommend the next investment. The result is not a promise to eliminate churn in three months. It is a functioning, repeatable post-sales foundation with clearer visibility of customer risk and opportunity.
How is a fractional Head of CS different from a consultant or a full-time hire? A fractional Head of Customer Success works inside the business and leads the work: improving onboarding, customer health, renewals and team capability, and staying involved until it sticks.
A consultant mainly gives advice or delivers a defined project. A full-time Head of CS does the job every day as an employee. Fractional leadership gives a growing SaaS company that senior experience without the cost or commitment of a full-time hire.
Do we need better customer success processes or more people? If your team is busy but customers still experience inconsistent onboarding, missed follow-ups, unclear ownership or surprise renewals, you probably need better customer success processes first. If the processes are clear and measured but there is simply more customer work than the team can handle, it is time to add people.
Often the answer is both: make the work visible and repeatable first, then hire for the capacity that remains.
What happens when a fractional Customer Success engagement ends? The aim of a fractional engagement is a post-sales function that runs without the fractional leader: documented playbooks, clear owners, a working operating rhythm, and measures the team already uses. If you are hiring a permanent Head of Customer Success, the engagement includes a handover plan so they inherit a working system rather than a blank page.
Where is SuccessByCS based, and which countries do you work with? SuccessByCS is based in New Zealand and works remotely with SaaS companies in New Zealand, Australia, Singapore, the United Kingdom, and on the West Coast of Canada and the United States. Sessions are scheduled to overlap with your team's working hours, and founders and customer-facing teams work directly with Chris Sparshott.
