Opening a frozen yoghurt shop

From chargeable weight to net sales

In a flat-price-per-weight format, yoghurt and toppings go onto the same scale. Chargeable product weight is the gross cup weight minus the empty container weight, known as the tare. Keep the weight unit consistent with the advertised price.

Separate indirect tax from sales revenue and use a consistent tax basis for costs. A tax-inclusive receipt is not all money available to run the shop.

Net product sales = chargeable weight sold × selling price per weight unit, excluding indirect tax.

Transactions and weight sold are different measures. Transaction count tells you how many purchases occurred; weight tells you how much product was billed. Average net sale per transaction connects the two. Record actual discounts and refunds rather than modelling every cup at the headline price.

Reconcile these records over the same period. Stock purchased this week is not necessarily stock consumed this week.

A topping earns its place through customer appeal as well as cost. Keep it when customers value it and its contribution, stock turnover and handling burden make sense together. Narrow or replace it when it repeatedly adds expense and waste without a demonstrated reason to visit or spend.

Air increases volume, not paid kilograms

Overrun is air incorporated into frozen product. Equipment manufacturer Stoelting explains that it changes volume and texture.² In a pay-by-weight shop, that does not translate into an equivalent increase in saleable weight.

Minimum staffing belongs in the cost of staying open

Some costs rise with each purchase. Others remain even when nobody walks in. Staff scheduled to supervise the shop, handle checkout and complete cleaning still need to be paid during quiet hours. Treat that minimum cover as a committed cost for the period.

Break-even transactions = (other fixed operating costs + minimum-cover payroll) ÷ average contribution per transaction.

Average contribution means average net sale less non-labour sale-linked costs and any genuinely volume-variable labour. Include unsold product consistently in the period's product costs. Do not deduct minimum-cover payroll again inside contribution.

Use the actual roster, including opening and closing work. Count the owner's duties once: either as paid owner work or as the cost of covering those duties. If busier trading requires another employee or shift, recalculate at that staffing step. A single average labour percentage can conceal both under-covered peaks and expensive quiet hours.

A busy precinct gives you potential customers, not a proven customer base. Nearby queues can reveal an occasion worth investigating, but they do not establish that people will choose your offer at your price.

Collect evidence in stages:

Observe competitors at the hours you intend to trade. Count passers-by separately from visible dessert purchases; note when purchases cannot be observed reliably. Repeat the exercise across weekdays, weekends and differing weather conditions.

If practical, test the intended product, serving size and regular price through a permitted pop-up or preorder offer before a major commitment. Record paid transactions, average paid spend, discount use and the reason for each visit. With consent, distinguish unique customers from returning purchasers. A return using another introductory discount is weaker evidence of ordinary-price demand than a return without one.

Set the decision threshold from your own cost model. Ask whether the observed purchases and contribution could support the proposed operating hours—not whether the test felt popular.

A warm-weather test leaves the quiet period unanswered

Use the local trading calendar, including weather, tourism, school terms and nearby destinations. Do not assume every shop follows the same seasonal pattern.

If you cannot test a quieter season before committing, seek anonymised monthly transaction records from genuinely comparable nearby shops, or the seller of an existing business. Ask about promotions, closures and changes in opening hours. Keep the unresolved quiet-period assumption visible in your decision; a successful short pilot does not settle it.

Send the relevant regulator a written description of the proposed operation. Ask for the classification, registration or permit route, plan review, training, inspection and fee requirements before committing to a fit-out.

Build your budget from written premises, equipment, servicing, ingredient, utility, insurance and payroll quotes. Record the location, quote date, currency—AUD, NZD, CAD, GBP or USD—and tax treatment. Include opening cash for delays, quiet trading and repairs, rather than using every available dollar on fit-out.

An existing shop may bring customers, staff and useful trading records. It may also bring ageing machines, a difficult lease and earnings that depend on the seller working unpaid or underpaid hours.

Australian government guidance recommends examining records and operations and considering your own time commitment.¹⁹ New Zealand's business-buying guidance adds checks on contracts, asset ownership, seasonal trends, stock and debts.²⁰ Use those checks in your purchase investigation:

In Canada, CRA guidance also makes allocation of the purchase price among assets, inventory and goodwill a tax issue to discuss with your adviser.²¹

Compare the actual franchise terms: initial investment, royalties, advertising charges, required suppliers, menu and pricing controls, support, renewal, transfer and exit. The US FTC notes that some royalties remain payable even when an outlet loses money. Its guide describes a US disclosure period of at least 14 days before signing or paying; do not apply that period to the other countries.²³

A smaller paid test can reduce the initial commitment, but it still needs the applicable food approvals. A shop is not a passive side hustle simply because customers serve themselves.

Before proceeding, bring together three things:

If one remains unresolved, spend on answering it before spending on a larger shop.
