BuffyFlowSell every day even when the internet doesn't.
BuffyFlow is the offline-first POS and invoice app for small shops. Ring up sales, track stock, and manage invoices on your phone — then sync when you're ready.
Local-first by design. Your sales are saved on the device first.
Features
Everything the counter needs. Nothing it doesn't.
Sell
New Sale is the heart of BuffyFlow. Scan a barcode, search your catalogue or add a custom item, pick a walk-in or registered customer, apply discounts and a delivery fee, then take cash or any payment method you set up — including partial payments.
- Barcode scan & product search
- Discounts and delivery fee
- Cash + configurable payments
Inventory
Your stock feeds every sale. Add products with SKU, barcode, pricing and images, set opening stock, track batches, and restock or adjust as goods come in.
- Products, batches, opening stock
- Restock and adjustments
- Low-stock and reorder alerts
Invoices
Run the whole commercial lifecycle: quotation to paid invoice to fulfillment. Payment status and delivery status stay separate, so you always know who owes you and what still has to go out.
- Convert quotation to order
- Payment vs fulfillment status
- Search, filter, cancel, share
Insights
Open the app and see the day: sales today and this month, outstanding balances, top selling products, plus financial and inventory analytics when you want to dig in.
- Today & month sales
- Outstanding balances
- Top products and analytics
Print & share
Hand over a thermal receipt at the counter or send a PDF invoice to a customer who prefers their phone. Same document, whichever your customer expects.
- Thermal receipts & invoices
- PDF share
- Invoice preview before you send

FAQ
Straight answers.
Does BuffyFlow really work offline?
Yes. Sales, stock changes and invoices save on the device first, so checkout never waits for a connection. Internet is optional at the till.
Is Google Sign-In the only way to log in?
Yes. BuffyFlow uses Google Sign-In only — there's no email and password account to manage.
Can I use it on more than one device?
Multiple devices and team sync are part of the Premium and Elite plans. Basic and Standard are single-device.
Can I print receipts?
You can print thermal receipts and invoices, and share the same document as a PDF.
What does cloud sync actually do?
It's an optional paid add-on that syncs your catalogue, customers and invoices across devices and keeps a backup. Your local data stays the source of truth.
Which phones does it run on?
BuffyFlow is available for Android and iOS.
