Payments for a garage sale in New Zealand: practical options and checklist

Quick overview

Garage sales in New Zealand usually work best with cash plus at least one cashless option. Cash is quick and familiar, but buyers increasingly expect to pay by card or bank transfer.

Decide your level of cashlessness ahead of time: purely cash, cash plus phone-based card payments, or cash plus card reader/payment link. Prepare signage so buyers know accepted methods before they get to the table.

• Let buyers know what you accept with a simple sign (e.g., “Cash, cards & bank transfer accepted”).
• Price items clearly and group small items together to make transactions faster.
• Keep a record of sales for your own tracking—paper or a simple spreadsheet/app.

Cash: how much float and handling tips

Cash is still widely used at garage sales. Prepare a float and keep cash handling simple to avoid mistakes and disputes.

Use a secure box or pouch and limit how much cash you keep on the table at once. Rotate someone to watch the cash if it’s busy.

• Suggested float: $50–$200 depending on scale. Include common NZ coins and notes: $2 and $1 coins, 50c, 20c and 10c coins, and $5, $10 and $20 notes.
• Set prices in sensible increments (e.g., round to nearest $0.10 or $0.50) to reduce small-change issues.
• Write simple receipts or use a receipt book for larger items; tally sales regularly during the event.

Card and contactless options without an EFTPOS machine

You don’t need a full EFTPOS terminal to accept cards. Several mobile solutions let you take cards via phone or tablet, or by sending a payment link to the buyer.

Consider whether you’ll need mobile data at your sale—some methods need internet. Have an offline backup (cash or card fallback) if connectivity is poor.

• Mobile card reader (plug-in or Bluetooth): connects to your smartphone and processes card taps/swipes. Usually charges per transaction.
• Payment links or invoices: create a payment request that a buyer pays by card or bank transfer from their phone; good for bigger items.
• Card on phone: some apps let the seller key in card details or the buyer scans a QR code to pay. Security and fees vary—choose a reputable provider.

Bank transfers and instant payments

Bank transfers are low-cost and convenient for some buyers, but they need to show the payment confirmation so you can release the item.

Ask buyers to make the transfer at your table and show the bank app confirmation or a screenshot. Allow for small delays when banks process payments.

Use a clear reference format so you can match payments (e.g., surname + item).

• Provide your account name, number and a preferred reference style on a printed sign or card.
• Accept bank transfers as a backup—not the only method for quick sales—unless you’re comfortable holding items until the money clears.
• If you’re unsure whether money has arrived, wait until you see the confirmation in your banking app before handing over the item.

Receipts, refunds and simple records

Keep a simple record of each sale: item, price, payment method, and a basic receipt for larger purchases. This reduces disputes and helps with end-of-day counting.

Decide your refund policy beforehand and display it (e.g., “All sales final” or “7-day returns with receipt”). Be clear and consistent.

• Handwritten receipts are fine—include date, item, amount and seller’s name.
• Consider using a phone app or spreadsheet to tally sales and reconcile with cash/card totals at the end.
• For donated or fundraiser items, note the purposes and give any paperwork the event requires.

Security and practical tips

Keep cash out of sight when not needed, don’t leave large amounts unattended, and rotate staff to minimise theft risk. For card payments, protect card data and follow best practices for privacy.

Make queues move faster by grouping small items, preparing change before the buyer pays, and agreeing on price before payment.

• Use a locked cash box or keep cash on your person in a money belt/pouch.
• Avoid writing down full card numbers or holding card details insecurely—use a reputable payment method instead.
• Label prices clearly and bundle small items (e.g., 3 books for $5) to speed sales.
