Case Study (Clinic) (2026): From Bulk-Billing Pressure to Mixed Billing — Funding a New Room Without Touching Cash Reserves
This is a “numbers + timeline” clinic case study. The clinic wanted to add one consult room fast, protect cash reserves, and shift to mixed billing without creating a cashflow crunch. The facility choice mattered as much as the build plan.

Case snapshot (what they wanted, and what had to stay protected)
The clinic was feeling bulk-billing pressure (more volume, same chair-time, rising costs). They wanted one extra consult room to increase capacity and support a controlled move to mixed billing.
The non-negotiable: keep cash reserves untouched. If they drained reserves to fund the build, the consequence was obvious — tighter supplier terms, less buffer for payroll weeks, and stress during the first 60–90 days of the billing shift.
| Item | Numbers (example scenario) |
|---|---|
| Build scope1 new consult room + small equipment bundle | $78,000 fitout + $42,000 equipment = $120,000 total project |
| Cash reserves (protected)Kept as buffer, not project funding | $95,000 retained (buffer for wages + suppliers + “billing shift” volatility) |
| Timeline targetFast delivery to catch demand | 6–8 weeks to completion (couldn’t wait for “save then build”) |

Facility choice: why they used a LOC (vs WCL vs invoice)
They considered three paths: a Business Line of Credit, a working capital loan, or an invoice-based facility. The job wasn’t “cheapest headline rate” — it was matching drawdowns to milestones without forcing cash out of the business.
They chose a LOC because the build had staged payments (deposit → progress → completion), and the clinic wanted redraw flexibility. If they picked the wrong facility, the consequence was mismatched settlement timing (funds arrive too late or too early) and cashflow pressure during the mixed-billing transition.
| Option | Why it fit / didn’t fit this build | What it solved in this case |
|---|---|---|
| LOC (chosen)Draw as needed | Matches staged milestones, keeps flexibility if scope shifts by 5–10%. | Protected reserves + funded progress payments cleanly. |
| Working capital loanFixed lump sum | Can work, but a lump sum arriving on day 1 can sit idle (or tempt overspend). | Better for “one-off” cash needs, less ideal for staged build timing. |
| Invoice-based facilityLinked to receivables | Strong if the problem is receivables timing, not construction milestones. | Useful later to stabilise cashflow, not the cleanest tool for fitout funding. |

Timeline + numbers (how the room paid for itself after mixed billing)
The build ran on a simple milestone plan: deposit to lock trades, progress at rough-in, final on practical completion. The key was keeping approval and supplier paperwork aligned so the install didn’t drift.
The billing shift was staged (not “flip a switch”). If the clinic went too aggressive too fast, the consequence could have been patient drop-off. So they used a gradual mix while the extra room increased capacity.
| Week | Action | Cash movement (example) |
|---|---|---|
| Week 1Plan + quote pack | Final scope, confirm staged payment schedule, lock start date. | $12,000 deposit paid from LOC draw (reserves untouched) |
| Week 3Rough-in complete | Progress payment released on milestone sign-off. | $48,000 progress paid from LOC draw |
| Week 6Practical completion | Final payment + equipment install/commissioning. | $60,000 final paid from LOC draw (total draw: $120,000) |
| Weeks 7–10Mixed billing staged | Introduce mixed billing in defined appointment types while capacity expands. | Revenue uplift begins as the new room increases throughput |
| Month 3Outcome snapshot | Room operating with stable utilisation; mixed billing becomes “normal”. | ~$38,000/month additional billings (example), breakeven ~3–4 months |

What made it work (and what would have blown up the timeline)
Two things protected the outcome: (1) facility matched the staged payments, and (2) they kept reserves as a real buffer while patient billing behaviour settled. It’s boring — and that’s why it works.
The most common failure mode is documentation mismatch (quote wording vs invoice timing vs facility draw rules). If that happens, the consequence is “re-quote → re-approval → rescheduled trades” (and you pay for delays twice: in cash and momentum).
| Do this | So you avoid this |
|---|---|
| Lock milestones + payment schedule before you lodge | Approval that doesn’t match supplier terms → last-minute amendments. |
| Keep reserves untouched for 60–90 days post switch | Stress decisions if patient mix shifts in the first few weeks. |
| Use the right tool for the job (build vs receivables) | Using a receivables tool to fund a build → timing mismatch and cash gaps. |
- Right facility = staged draws that match build milestones (and protects reserves).
- Wrong facility = timing mismatch → rework → delayed opening and delayed revenue.
- If your clinic’s “real problem” is receivables timing, the cleaner lever is Invoice Finance — not forcing a build into the wrong structure.
