Hearing clinic bookkeeping: one visit, three tax treatments, four payers

Three revenue lines, three GST/HST answers

The diagnostic side of a hearing clinic and the retail side sit on opposite ends of the GST/HST spectrum, and the till often mixes a third answer in on the same receipt.

We map the point-of-sale system to those four lines once, so a receipt that bundles an assessment, a device, and a pack of batteries splits correctly without anyone at the front desk making a judgment call. See the difference between zero-rated and exempt supplies for the underlying rule.

Four payers, one patient file

A single fitting can be funded by up to four different sources, and each reconciles on its own schedule. The Ontario Assistive Devices Program pays a fixed contribution once a claim is approved, leaving the client responsible for the balance; a client's extended health plan may cover a further slice on assignment; WSIB pays for a claim tied to occupational noise exposure; and Veterans Affairs Canada funds devices for eligible veterans directly. We book each ADP, insurer, WSIB, or VAC claim as a receivable the day it is submitted, not the day it is paid, and reconcile the remittance against the claim so a partial payment or a rejected line gets caught and resubmitted instead of aging into a write-off.

Trial periods turn a sale into a temporary loan

Ontario practice is built around a trial period before a hearing aid sale is final, which means a device that leaves the clinic today may come back inside the return window as a full or partial refund. Recognizing the full sale price on delivery overstates revenue for every trial that does not convert, so we hold new fittings in a short-term suspense account until the trial period lapses, then recognize the revenue and release the device from demo inventory. Demo and loaner units themselves are tracked as a separate inventory pool — valued at cost, not retail price — so a unit circulating between patients during a trial does not get double-counted as both inventory and a completed sale.

Manufacturer programs move the cost side, not just the price tag

Clinics typically buy through a manufacturer purchasing program — Phonak, Oticon, Widex, Signia, Starkey, and ReSound all run volume-based pricing and rebate structures — so the invoice cost on a given model can shift through the year as your purchase volume crosses a rebate tier. We tie rebate credits back to the purchase batch they relate to rather than dumping them into miscellaneous income, which keeps the true landed cost of each device visible for margin reporting instead of hidden inside a lump-sum credit memo months later.

• Serialized inventory — each hearing aid is tracked by serial number from purchase order to fitting, so warranty claims and trial returns both tie back to a specific unit and its cost.
• Repair and loaner cycles — units sent for manufacturer repair are moved out of sellable inventory and back in on return, so the count on the shelf matches the count in the system.
• ADP recertification files — ADP funding can recur on a set cycle for eligible clients, so we flag repeat-claim patients rather than treating every claim as a one-off.

Where the border shows up in the books

Several major manufacturers price and rebate in US dollars even when the invoice arrives from a Canadian distributor, so a chunk of your cost of goods sold moves with the exchange rate independent of anything happening in your local market. We record purchases at the exchange rate on the invoice date and true up rebate credits at the rate in effect when they land, so currency movement shows up as its own line rather than blurring into device margin.
