Can a POS system work without internet?

Yes, with Kynetik POS. Unlike most POS systems that freeze when the internet goes down, Kynetik stores your entire product catalog, customer data, and pricing locally on each device. You can process cash sales, look up products, and serve customers without any internet connection.

What happens to sales made offline?

Offline sales are stored securely on your device with full timestamps, staff info, and transaction details. When your internet connection returns, all sales automatically sync to BigCommerce—orders are created, inventory is updated, and customer records are maintained.

Can I accept card payments offline?

Card payments require an internet connection to process with the payment provider. However, Kynetik's offline mode lets you continue selling with cash and other offline payment methods. Gift cards and store credit with stored balances can also be used offline.

Does offline mode work at pop-up events and markets?

Offline mode is perfect for pop-ups, markets, and events with unreliable WiFi. Load your catalog before the event, process sales all day with or without connectivity, and sync everything when you're back at the store or have internet access.

Can I process sales without internet on Kynetik POS?

Yes, Kynetik POS works fully offline for cash transactions. You can browse products, build carts, and complete cash sales without any internet connection. Card payments require connectivity for authorization, but cash sales work completely offline.

How does Kynetik sync offline transactions with BigCommerce?

When you reconnect to the internet, Kynetik automatically syncs all offline transactions to BigCommerce. This includes sales, inventory adjustments, and customer updates. The sync happens in the background without interrupting your work.

What happens if I sell the same product online and offline simultaneously?

Kynetik has smart conflict resolution. When you come back online, it reconciles your offline sales with any online activity. If inventory conflicts occur, Kynetik alerts you and prevents overselling.

How much data is stored locally on the device?

Kynetik stores your complete product catalog, customer records, and pending transactions locally. For most stores, this is under 100MB. The data syncs incrementally, so only changes are transferred, not the entire database.

Real-World Scenarios

Offline mode isn't just a backup plan—it's how many retailers operate every day.

Pop-up Shop at a Festival

Selling at an outdoor event with unreliable WiFi? Kynetik keeps working. Process cash sales all day, and everything syncs when you get back to reliable internet.

Taking orders tableside at a restaurant or on the showroom floor? Move freely without worrying about WiFi dead zones.

The Technical Details

For those who want to understand how it works under the hood.

Local Database

Kynetik uses SQLite on-device to store your product catalog, customer records, and pending transactions. This isn't a cache—it's your primary data source. Network requests enhance and update local data; they don't replace it.

Optimistic Updates

When you make a sale, the local database updates immediately. The UI reflects the change instantly. Network sync happens in the background. If the sync fails, the transaction is queued for retry—you see the sale as pending until it's confirmed by BigCommerce.

Inventory Tracking

Stock levels are tracked locally. When you sell an item, local inventory decrements immediately. This prevents overselling even when offline. When sync occurs, any conflicts between local and remote inventory are resolved intelligently.

Payment Handling

Card payments require network connectivity (the payment processor needs to authorize). Cash payments work fully offline. Mixed transactions (part cash, part card) gracefully handle the network requirement for the card portion.

Never Lose a Sale to Bad Internet
