Get started
Copy the template spreadsheet, deploy the backend, install the app on your phone or tablet (no app store needed), paste your license key. Done once per device, then forget it.
Categories, products, parents and variants, bundles. Plus a walkthrough of every column (Active, BringToShow, FavRank, ParentSKU) so you know exactly what each one does before you touch it.
At the booth
Tax rates, dates, location, booth fees, mileage, commission tiers. Everything that goes into a single market or fair.
Adding items, taking payment, tipping, tax-exempt sales, customer receipts via QR. Plus parking a cart when a second customer walks up mid-sale.
If you use Square, a one-tap handoff opens Square with the cart total pre-filled, takes the card there, and records the sale back automatically. Optional; no setup if you don't use Square.
Pass an in-progress cart from one device to another with a 4-digit code. For two-person booths where the helper at the front needs to bring in the owner for a question.
Set up "any 4 bookmarks for $20" style deals that auto-apply in the cart. Build them from the Edit bundle form in Settings, no spreadsheet required.
Take a deposit, track production, mark Ready. Auto-emails the customer when their piece is done.
Setup QR for a second phone or tablet so a helper at the booth can ring sales too.
Inventory & reports
Bulk-load your catalog from a CSV or another spreadsheet. Map their columns to ours, preview, commit.
Production sheet, off-cycle adjustments, low-stock badges, and end-of-event posting to keep counts honest.
Per-event P&L tells you which fairs to do again. Walks through COGS (and how to estimate it if you don't track exact materials cost), filling in the Cost column, and reading the per-event report.
Print Avery 5160 / 5167 sheets straight from the spreadsheet, then scan with any phone camera at the booth. No special hardware needed.
Per-event P&L (live, while the event is still running), top sellers, expenses, multi-state tax filing. Numbers your accountant actually needs.
Card and Venmo Business fees come off the top before your deposit hits. Two paths: tax-accurate (Expenses sheet) and live-during-event (in-app estimate). Plus the Venmo personal vs Business rules of the road.
Track inventory at consignment venues — a craft fair drop-off, a permanent space at a consignment shop, anything in between. Stock in, payouts, returns, all tied to your sheet.
Daily auto-backup of your spreadsheet to your Drive, plus how to restore if you ever need to.
Customer-facing extras
Drop SKU-named photos into a Drive folder, paste the folder URL into Settings, and your booth UI gets thumbnails on every product button. Visual recognition is faster than text at booth speed.
One menu click and the app creates both Google Forms for you. Customers scan a QR at the booth to request products they want or sign up for your mailing list. Hands-off lead capture between sales.
Reference
Business name, tax mode, customer notifications, API secret, and the rest of the config you'll touch occasionally.
Common gotchas: sync issues, stale caches, license warnings, and what to check first when something feels off.
When the app shows an update card in Settings, this walks through what to do — which clicks happen on your computer (in the spreadsheet editor) versus your phone (in the app), with screenshots.
