Is the Garage Sale App free?
Yes, completely free. There is no subscription, no account required, and no paid tier. If you find it useful, a
Buy Me a Coffee is always appreciated, but entirely optional.
Does it work offline? Do I need Wi-Fi at my garage sale?
Yes. GS App is a Progressive Web App (PWA) that caches itself after the first load. Once installed, it runs entirely offline — no internet connection is needed on sale day. All your data (inventory, parties, transactions) is stored locally on your device unless you enable Google Drive backups (recommended).
Does it work on iPhone and Android? How can I install it?
Yes, on both. On iPhone, open
salesapp.wozserv.com in Safari, tap the Share button, and choose "Add to Home Screen." On Android, open the site in Chrome and tap "Install App" when prompted. You can also just use it in any mobile or computer internet browser without installing.
How many sellers (parties) can I set up?
There is no hard limit. In practice, garage sales with 4-8 sellers work great. Each seller gets a name and a color, and their sales are tracked independently throughout the day.
How does barcode scanning work?
GS App uses your device's camera to scan UPC bar codes. When you register an inventory item, you can scan its barcode to attach a UPC to it. During a sale, tapping the barcode button and scanning an item's UPC instantly finds it in inventory and adds it to the cart. It works on any device with a camera — phone, tablet, or laptop.
Is my data saved if I close the browser or restart my phone?
Yes. All data — inventory, parties, settings, and transaction history — is saved to your device's local storage. It persists across browser restarts and phone reboots as long as you don't clear your browser's site data. However, it is highly recommended that you enable Google Drive backups to ensure your data is safe. Alternatively, you can also export your data as a JSON backup from the Settings screen.
I'm nervous about losing my data but I don't want to use Google Drive to save my data, what can I do?
On the setting screen, there is a Data section where you can export and import the full state of the Garage Sale App. When you export, the data file is saved to your device's file system, usually under Downloads. If you are on an iPhone or iPad with iCloud Drive, it will be in the Files app → Locations → iCloud Drive → Downloads. The file will be named in the form of "gsapp-backup-yyyy-mm-dd.json".
Can I use Google Drive to save my data?
Yes - there are two ways:
- You can click the "Sign in with Google" button on the splash screen that first appears when you load the app (you may not see it if you check the "Don't show this again" checkbox).
- On the Sale screen, click the settings button (gear icon in the upper-right), scroll down to the Google Drive backup section and click the "Sign in with Google" button.
Where can I find the saved data on my Google Drive? And can I remove it?
Unfortunately, you cannot "see" the data on your drive however you can see a managed app in your Google Drive settings. To remove this data:
- Open drive.google.com/drive/settings
- Click Manage Apps
- In the list, find "Garage Sale App"
- Click Options
- Click Delete hidden app data
You can also sign out in Settings → Google Drive Backup → Sign out, which stops any future syncing.
Does the Garage Sale App process payments or connect to payment gateways?
No. GS App is a payment tracking tool, not a payment processor. It does not connect to Stripe, Square, PayPal, Venmo, or any other payment service. You collect money however the buyer wants to pay — cash, Venmo, check, whatever — then record the method and amount in the app. GS App aggregates those totals so you know exactly how much came in and via which method at the end of the day.
Can I track Venmo, PayPal, or other non-cash payments?
Yes — as custom payment method labels. Go to Settings → Payment Methods and add any labels you want (e.g. Venmo, PayPal, Square, check). At checkout, you record which method the buyer used and how much. GS App does not open or connect to those apps; you handle that transaction yourself and simply log it here. Totals per payment method appear in the Reports screen.
Does it calculate sales tax?
Yes. Enable tax in Settings and enter your local rate. Tax is calculated at checkout on all taxable items. Individual inventory items can be marked non-taxable (e.g. clothing in states with a clothing exemption). The Reports screen correctly apportions tax to each seller based on their taxable sales only.
Can I use this for a flea market or community sale, not just a garage sale?
Absolutely. GS App works for any multi-seller cash-register scenario: neighborhood sales, school fundraisers, church rummage sales, flea market booths, craft fairs, and more. The "parties" are just sellers — you can name them anything.
