Orthodontist bookkeeping: why the contract fee isn't this month's revenue

The contract fee is banked long before it's earned

An orthodontic case fee is usually set once, at the consultation where the treatment contract is signed: a down payment at start, then equal payments on a pre-authorized debit schedule running to the end of active treatment. Record that full fee as revenue the day it's contracted and the practice looks unrealistically strong in months with several new starts, then unrealistically weak in a quiet month even though existing patients are still being seen and paying on schedule.

We treat the unearned portion of every signed contract as a liability, not income, from day one. That single change is what makes a monthly profit and loss statement tell the truth about a case-based practice, and it is the first thing we set up when we take on a new ortho file — usually inside QuickBooks Online, reconciled against the patient ledger your practice management system already keeps.

Month-end starts with the treatment coordinator's new-case log rather than the bank feed, because a busy signing month and a busy banking month rarely land on the same calendar month. Deposits are matched to the contract that generated them, and any deposit that cannot be tied to a specific case gets flagged rather than parked in a suspense account until year-end.

A recognition schedule that matches the treatment plan

Each signed case gets its own recognition schedule: total fee, estimated treatment months, and a monthly release amount. Practice management platforms such as Ortho2 or Cloud9 track the clinical side of that timeline already; our job is to mirror it in the accounting so collections and recognition are reconciled monthly rather than assumed to match.

Because most orthodontic services are exempt while the appliance itself is zero-rated for GST/HST, the same contract usually needs two invoice lines, not one — a split our tax services page covers in depth, but that starts in the books, at the point the contract is entered.

Aligner and lab costs need their own ledger line

A per-case aligner fee — Invisalign or a comparable clear-aligner system — and any lab invoices for fixed appliances or retainers are a direct cost of that specific case, not a general supplies expense. We post them as cost of treatment and track the total against the case fee it belongs to, the same discipline a general dental practice applies to crown-and-bridge lab bills. A rising lab-cost percentage across the practice is often the first sign that case fees have not kept pace with supplier pricing.

Clear-aligner fees are frequently invoiced in USD from a US manufacturer, so each invoice is booked at the exchange rate on the invoice date and settled at the rate on the payment date, with the difference recorded as a currency gain or loss — the same routine covered in how to record USD transactions in Canadian books. Left untracked, that FX drift quietly erodes the margin on every clear-aligner case.

Refunds, transfers, and the unearned-fee number you already have

Patients relocate mid-treatment, and families sometimes discontinue. Either way, the practice owes only the unearned portion of the fee — and because that liability has been tracked from the start, the refund or transfer amount is a lookup, not a negotiation. When a patient transfers to another orthodontist, the standard courtesy is to send records and prorate the remaining fee between the two offices; our ledger already has both numbers to hand.

Because most new patients arrive through a referring general dentist rather than walk-in traffic, we also code referral-source data into the bookkeeping where it's captured, so a practice can see which referral relationships are actually converting into signed cases rather than guessing from memory. That view matters more for an orthodontic practice than a general one, since there is no recall-driven hygiene schedule constantly refilling the new-patient pipeline — new starts largely depend on relationships with the general dentists sending patients your way.

Multi-location practices add one more wrinkle: the same treatment can be started at one office and finished at another as the orthodontist rotates between chairs on different days of the week. We keep the deferred-revenue schedule attached to the patient and the case, not the location, so a mid-treatment move between your own offices never looks like a transfer.
