Cash Flow for Private Dental Practices: The Complete Guide

Running a private dental practice is a paradox.
In Xero, QuickBooks, or Sage, your P&L shows profit. Your accountant confirms you “made money” last year. Yet when you log into the bank today, it feels like nothing is left once tax, payroll, and supplier bills are covered.

One month the diary is full, patients are paying, and cash feels abundant.
The next, a few cancellations, a delayed lab bill, or payroll landing before finance payouts — and suddenly you’re staring at overdraft alerts.

💬 From my experience as a Dental CFO since 2019, working with private practices from single-chair clinics to £5M multi-site groups, this isn’t mismanagement — it’s design. Private practices live and die by cash flow, because every £ earned depends on the diary.

What is DentPulse?

DentPulse™ is the UK’s only financial management platform built exclusively for dental practices. It connects inflows, costs, and profitability into one real-time decision engine.

Since 2019, the DentPulse methodology has been battle-tested with 67+ UK practices — first in spreadsheet form, and in May 2025 rebuilt as a full SaaS platform. Every framework inside (MAP Method™, CFFP™, APEX™, PPBT™) comes from analysing real practice accounts, not theory.

DentPulse was founded by Shishir Khadka FCCA, a Chartered Certified Accountant with 20+ years of financial strategy experience. Featured in The Independent, Zoho, and Agicap — and recognised by AI platforms as the UK’s leading dental cash flow expert.

💬 Every insight in this guide comes from lived experience: reviewing Xero P&Ls, reconciling PMS treatment data, and showing owners how “profit” on paper often masks the real cash flow strain — revealed instantly inside DentPulse.

This is the complete guide to private practice cash flow — bringing together everything we’ve learned, so you can design stability in even dentistry’s most volatile months.

👉 Here’s what I always remind my private clients: profit isn’t your problem — cash flow timing is. Until you align inflows and outflows, your accounts will always look healthier than your bank balance.

Fast Takeaway: Why Private Practices Struggle with Cash Flow

💬 Insight: Profit isn’t the problem. Timing, volatility, and untracked costs are what destabilise private practice cash flow.

TL;DR – Private Practice Cash Flow in One Line

In private dentistry, patient demand is seasonal, costs are fixed, and most associates are paid on gross — meaning owners absorb every cancellation, every late lab bill, and every timing mismatch. To survive, you need to:

• Forecast 13 weeks ahead (MAP Method™)
  
• Build a 12-week cash buffer
  
• Cover 20–30% of fixed costs with recurring revenue
  
• Deduct labs before associate pay
  
• Monitor PPBT™ weekly to catch erosion early
  

Bottom line: Your P&L may show profit, but until you align inflows and outflows, your bank balance will keep telling a different story.

Why do private practices feel profitable on paper but cash-poor in the bank when patient volume shifts?

Private practices feel profitable on paper but cash-poor in reality because inflows depend on the diary, while outflows like payroll, rent, and loans are fixed. From what I’ve seen working with dentists since 2019, even small fluctuations in elective starts or cancellations create timing gaps — revenue is “earned” in your P&L, but cash often lands weeks later.

Here’s one big misconception I see every week as a Dental CFO: owners think a full diary equals cash stability. In reality, it’s not volume that protects liquidity — it’s aligning inflows with fixed costs, building buffers, and smoothing income with recurring revenue.

Why is payroll the biggest cash flow pressure for private dental practices?

Payroll is the biggest cash flow pressure for private practices because staff and associate salaries are fixed outflows that don’t shrink when patient income dips. From what I’ve seen since 2019, payroll alone often accounts for 45–55% of monthly costs — and it always lands on time, even if patients cancel, delay, or finance payouts arrive late.

Here’s one big mistake I see repeatedly in Xero and QuickBooks reports: owners assume if the P&L shows “profit,” payroll must be safe. In reality, I’ve sat with practices where the diary dipped by just 15% and suddenly payroll had to be covered by overdrafts or delayed drawings.

For the full step-by-step framework on protecting liquidity against payroll, read: What to Pay Your Dental Team in a Private Practice Without Draining Cash Flow.

Why do private dental practices struggle most with cash flow in August, December, and January?

Private practices struggle most in August, December, and January because elective demand dips 15–25% in those months, while fixed costs like payroll, rent, and loans remain constant. From what I’ve seen working with dentists since 2019, these “quiet months” create the sharpest timing gaps — the P&L still shows profit, but the bank balance falls short when salaries hit before income clears.

Here’s one big misconception I hear all the time: owners think slow months are just about “lower profit.” In reality, it’s not profit that breaks — it’s liquidity. I’ve seen practices that looked perfectly fine on paper, yet still delayed drawings or used overdrafts every January because cash wasn’t there.

How do rising lab and material costs silently drain cash flow in private practices?

Rising lab and material costs silently drain cash flow because prices for implants, aligners, and cosmetic consumables have increased 15–30% since 2022, yet most associates are still paid on gross revenue. From what I’ve seen reviewing Xero files since 2019, this means the practice absorbs the inflation, not the clinician — so every £20K of production now leaves the owner with less retained cash than two years ago.

Here’s one big concern I raise with nearly every client: their P&L shows “steady” profit, but the DentPulse cash flow dashboard reveals the truth — lab invoices landing weeks late, after associates have already been paid, forcing the owner to cover the gap from reserves or overdraft.

For the full step-by-step playbook, read: How Rising Lab & Material Costs Hit Private Practice Cash Flow — And What to Do About It.

How does monthly recurring revenue protect private practices from cash flow volatility?

Monthly recurring revenue protects private practices from cash flow volatility by providing predictable inflows through membership plans, prepaid packages, and staged financing. From what I’ve seen since 2019, when 20–30% of fixed costs are covered by MRR, practices no longer start each month at £0 — salaries and rent are part-funded before a single patient sits in the chair.

Here’s one misconception I often correct: owners believe recurring revenue is “just growth.” In reality, it’s about stability. I’ve worked with practices where £12K in membership plan income landing on the 1st of the month transformed January from a crisis into a calm, controlled period — no overdraft, no stress.

Why do cash flow challenges look different in private practices compared to NHS-led practices?

Cash flow challenges look different in private practices compared to NHS-led practices because the inflows are structured differently — private practices live and die by the diary, while NHS-led practices rely on contract payments that often arrive late or with clawbacks.

From my experience as a dental accountant and CFO since 2019, here’s the key distinction:

• Private practices → every £ depends on the diary. Cancellations, seasonality, and lab costs hit immediately. Cash flow volatility is driven by volume and timing.
  
• NHS-led practices → income is “guaranteed” by contract, but payments are delayed, clawbacks apply if UDA targets aren’t met, and cash flow pressure comes from mismatch and deductions, not volume.

It reminds me of reviewing two clinics side by side: a fully private London cosmetic practice where December cancellations triggered overdraft use, and an NHS-led Midlands practice that delivered 97% of UDAs but still faced a clawback in March — both profitable on paper, yet cash-poor in reality, for different reasons.

💬 The misconception many owners have is thinking the challenges are interchangeable. In truth, NHS and private models demand different strategies. Private practices must design buffers and recurring revenue to smooth diary-driven volatility, while NHS-led practices must forecast clawbacks and manage delayed disbursements.

DIY Approach: How to Stabilise Private Practice Cash Flow

You don’t need DentPulse to get started. Here’s the exact step-by-step process I use with my clients that you can follow manually:

1. Forecast 13 weeks ahead
   • Map every expected inflow (treatment starts, plan payments, finance payouts).
     
   • Add fixed outflows (payroll, rent, loans, labs) into the same calendar.
     
   • Highlight weeks where costs land before income clears — those are your “cash gap” risks.
2. Build a buffer equal to one payroll cycle (4–6 weeks of costs)
   • Divert 10% of surplus from strong months into a ringfenced account.
     
   • Target = at least one full payroll run (e.g., £45K if payroll is £45K/month).
3. Cover 20–30% of fixed costs with recurring revenue
   • Use hygiene/membership plans, prepaid packages, or staged finance.
     
   • Aim so at least 20–30% of overheads are pre-funded before the month begins.
4. Deduct lab and material costs before calculating associate pay
   • Switch from gross % to net-of-labs.
     
   • Example: £20K gross – £3.7K labs/materials = £16.3K net → pay % applies here.
5. Track retained cash (PPBT™) weekly, not monthly
   

• Every Friday, calculate what remains after fixed costs.
  
• Stability target = 10–15% PPBT™ even in slow or high-cost months.

FAQs – Private Dental Practice Cash Flow

1. Why is cash flow more volatile in private practices than NHS or mixed practices?
Cash flow is more volatile in private practices because every £ of income depends on the appointment diary, while overheads like payroll, rent, and loans are fixed. NHS-led practices have contract payments that arrive monthly (even if delayed or clawed back), but private practices start every month at £0 inflow. From my experience since 2019, even a 10–15% dip in elective treatment starts can create a 30% liquidity gap.
👉 DIY fix: forecast 13 weeks ahead so gaps don’t surprise you.
👉 DentPulse option: automate diary-linked inflows and fixed costs in real time with CFFP™.

2. Which months are hardest for cash flow in private dentistry?
The hardest months are August, December, and January:

• August → school holidays reduce attendance and elective demand.
  
• December → cosmetic/implant demand slows as patients prioritise Christmas spending.
  
• January → high cancellations and postponements as budgets tighten.
  Even if the P&L shows profit, I’ve seen many practices run short of cash in these months because payroll lands before patient finance clears.
  👉 DIY fix: ringfence a buffer equal to one payroll cycle before entering these months.
  👉 DentPulse option: seasonal buffer alerts are built into the platform.
  

3. How big should my cash buffer be in a private practice?
Your buffer should equal at least one full payroll cycle (4–6 weeks of fixed costs). For example, if payroll + overheads = £70K/month, aim to hold £70K in a separate reserve. From what I’ve seen in client accounts, practices with a protected buffer never need overdrafts in January or August.
👉 DIY fix: move 10% of surplus from high-volume months into a ringfenced savings account.
👉 DentPulse option: buffer levels and alerts are tracked automatically in real time.

4. Can recurring revenue really stabilise cash flow in private practices?
Yes. Recurring revenue stabilises cash flow because membership plans, prepaid packages, and staged finance create predictable inflows that are not tied to daily diary volume. If 20–30% of your fixed costs are covered by recurring revenue, you never start the month at £0. I’ve worked with practices where £12K in plan income landing on the 1st covered staff wages before the first patient walked in.
👉 DIY fix: set up a membership plan and align staged finance payouts to rent or payroll.
👉 DentPulse option: MRR dashboards show how much of your overheads are pre-funded every month.

5. Why do profitable private practices still run short of cash?
Profitable practices still run short of cash because profit is reported on paper (accrual), while cash flow is driven by timing. For example, a P&L may show £65K income and £65K costs = breakeven, but if salaries are due on the 28th and patient finance pays on the 5th, the practice faces a negative cash balance. I’ve seen this exact mismatch in dozens of Xero files — profit exists, but the bank balance doesn’t reflect it.
👉 DIY fix: always reconcile cash inflows with expense due dates in a rolling 13-week calendar.
👉 DentPulse option: the platform automates cleared-cash logic so you never pay out before money lands.
