Key takeaways
- The device daily limit applies to each device separately, so two devices at $2,000 each put up to $4,000 at risk.
- Tap to Pay on iPhone and Android doesn't work offline. A phone-only setup can't take any cards once the signal drops.
- Only the POS Terminal's always-on authorization gets a live approval during an outage. Every other offline card sale is unverified until it syncs.
- On every offline card sale, get an email or phone number. If the payment declines later, that's your only way to collect.
Shopify POS offline mode keeps you selling when the connection drops. Every Shopify POS user can take cash and custom payment methods offline. Inserted or tapped cards also work, but only if you turned on offline payments in your Shopify admin beforehand and you're using a supported reader. Those card payments aren't authorized at the counter. The device stores them and sends them for processing when it reconnects. If the card issuer declines one at that point, you take the loss.
That's a fair trade for a farmers market booth or a pop-up with a line, as long as you decide in advance how much unverified money you're willing to hold. Shopify gives you two limits to control that, and setting them well matters more than any other part of the setup.
Offline Checkout, Offline Payments and Always-On Authorization
Shopify uses three terms that sound alike but carry very different risk.
Offline checkout lets you take cash and any custom payment methods you've set up, such as checks or a third-party terminal, with no internet. Shopify's help center says it's available to all Shopify POS users. Staff need the "Switch device to offline checkout" role permission, and you can require a manager's PIN before anyone turns it on.
Offline payments extends offline checkout to credit and debit cards. You turn it on in your Shopify admin, and Shopify captures the card payments after the device reconnects. This is the mode that carries the risk of a later decline.
Always-on card authorization applies only to the POS Terminal reader used with Shopify Payments. If the POS device loses internet but the reader can still reach the payment processor, the reader authorizes card-present payments in real time. That's a live authorization, so the customer's bank approves or declines before they walk away. Shopify attaches conditions: your local Wi-Fi network has to stay up, and while you're offline you can't restart the router or switch networks unless the new network has a confirmed connection.
What Shopify POS Offline Mode Can't Do
Offline mode finishes simple sales of items already on the device. Shopify's offline features page lists what stops working. You can't process exchanges, returns or voids. Discount codes and automatic discounts don't apply, though manual discounts still work. Saved and shared carts are unavailable, and so are ship-to-customer orders. Orders and inventory stop syncing with your admin until you reconnect, and emailed receipts wait for a connection too.
The card restrictions catch more vendors off guard. Shopify doesn't support swiped cards, Tap to Pay on iPhone, Tap to Pay on Android or manual card entry while offline. Phone-only setups are the trap here. A shopper tapping a card on a Tap & Chip reader is fine. A vendor whose only "reader" is Tap to Pay on their own phone can't take cards at all once the signal goes.
You also can't create new products offline. If you sell one-off pieces, add a few generic items at your common price points before the event. You can ring those up and fix the records later.
Set up Offline Card Payments While You Still Have Signal
You can't turn this on once you're already offline. Shopify requires POS app version 9.14.0 or later and a compatible reader: POS Go, POS Terminal, Tap & Chip, Chipper 2X BT, WisePad 3 or Chip & Swipe Reader. Each staff member who will take cards also needs the "Accept offline credit and debit payments" permission. If you're still picking hardware, our comparison of Shopify POS card readers by store type covers the trade-offs.
- In your Shopify admin, go to Sales channels > Point of Sale.
- Under Customize the in-store experience, click Edit for POS app, then click Checkout.
- Turn on Allow offline payments and enter a device daily limit and a transaction limit (the next section shows how to choose them).
- Under Settings > Users > Roles, give the right roles both offline permissions.
- Update the POS app and the reader the day before. Shopify's troubleshooting page notes that a Tap & Chip reader needing a software update won't connect until its battery is at least 50% charged.
- Do a dry run. Put the device in airplane mode, sell a small item to your own card, reconnect and confirm the payment captured.
Choosing Your Offline Payment Limits: A Worked Example
Shopify asks for two numbers. The transaction limit caps each order and counts every card used on it. With a $100 limit, two cards can split a sale as long as the total stays at or under $100. The device daily limit caps the total of all offline card payments on one device. Shopify's help page uses $100 and $5,000 as examples, but those are illustrations, not defaults. One POS consultancy notes that Shopify doesn't publish default values, so the numbers are yours to pick.
Vendors often miss that the daily limit applies to each device, while the transaction limit applies across all your locations. Two iPads with a $2,000 daily limit each put up to $4,000 at risk, not $2,000.
Illustrative example, with every number assumed: a ceramics vendor works a Saturday craft fair with two devices, each paired to a Tap & Chip reader. Most of her sales are mugs and bowls between $25 and $60, plus a few serving sets at $240. Card sales on a normal Saturday run about $3,000 over an eight-hour day, or $375 an hour. She won't hand over more than $100 of goods per order without a confirmed payment. And she can absorb $600 in losses for the day without hurting next week's restock.
| Setting | Her Choice | What It Does |
|---|---|---|
| Transaction limit | $100 | Mugs and bowls go through offline; a $240 serving set won't |
| Device daily limit | $300 per device | Two devices cap her total exposure at $600 |
Say the signal drops for three hours. At her usual pace that's about $1,125 in card sales ($375 × 3). Her limits let $600 of mug and bowl sales go through offline. The other $525, including any serving sets sold in that window, needs cash, a short wait or a walk to find signal.
Now compare a looser setup. If she had set a $5,000 daily limit on each device and a transaction limit above $240, the whole $1,125 would sit on unverified cards. A single serving-set decline would then cost her $240 instead of at most $100.
The right lean depends on what you sell. Low-ticket, high-volume sellers such as coffee carts can run higher daily limits because each decline is small. Sellers with a few big tickets should keep the transaction limit low and move those sales to cash or a live connection.
Who Pays When an Offline Payment Declines
You do. Shopify warns that offline payments can be declined for reasons including insufficient funds or a lost or stolen card. Its fix is for you to contact the customer, using the email or phone number collected on the order, and collect the payment again. By then the customer already has the goods. Plan as though every offline decline is lost money unless you can reach the buyer.
A few habits shrink that risk. Ask for an email or phone number on every offline card sale; offering an emailed receipt is the natural way to get one. Reconnect quickly, because Shopify's guidance is to reconnect as soon as possible and ideally within 24 hours. Keep the device powered on and signed in until it syncs, since the stored payments live on that device. Until they process, those orders show a "Payment pending" badge.
A declined offline payment is different from a dispute. A payment that settles can still turn into a chargeback weeks later, and our guide to responding to a chargeback in Shopify walks through that process. For the issuer's side of a decline, see why issuers turn down good customers.
Keep a Live Connection and You'll Rarely Need Offline Mode
A live authorization always carries less risk than a stored payment, so the best offline plan is a better connection. Venue Wi-Fi at fairs and festivals is often shared or overloaded, and a single carrier's cell network can jam when a crowd gathers.
| Backup | Good Fit | Watch For |
|---|---|---|
| Phone hotspot | Occasional pop-ups | Drains the phone you may also need for calls |
| Dedicated mobile hotspot | Regular market vendors | Separate data plan and charging |
| Hotspot on a second carrier | Big events where one network jams | Two plans to pay for |
| Cellular signal booster | Venues with weak coverage | Upfront cost; needs some signal to boost |
Some vendors also carry a separate card terminal from a merchant services provider as a backup and record those sales in Shopify POS as a custom payment method, which offline checkout supports. That terminal runs on its own merchant account and needs its own connection, so ask the provider how it behaves without signal before you count on it. MannyPay sells mobile card terminals and handheld payment terminals for selling on the go.
Close Out Before You Pack Up
Reconnect every device to a stable network and leave the POS app open until it finishes syncing. Shopify also lets you force a sync manually. Then filter your orders for anything still pending or declined, and contact those customers that evening while the sale is fresh in their minds. Count the cash drawer against the cash sales in POS. Check that inventory reflects what sold at the booth, and compare totals with any paper tally you kept during the outage.
Offline card sales carry no separate offline fee. Standard transaction fees apply once they sync. Our breakdown of Shopify POS in-person card rates covers what you'll pay, and the Shopify payout schedule explains when the money lands.
Before your next event, open your Point of Sale settings and set both limits from your own ticket sizes and the loss you can absorb, multiplied by the number of devices you'll run. Then run the airplane-mode test with your own card. If you want a second opinion on your in-person setup, request a free quote from MannyPay and a specialist will respond within one business day.
