Shopify POS Offline Mode: What Works Without Internet

Updated August 2026. This guide previously stated that Shopify POS cannot process cards offline. That is no longer accurate — offline card payments are supported, with conditions worth understanding before you rely on them.

The short answer

Yes, Shopify POS can accept card payments while offline. It is off by default, it requires setup you must do before the connection drops, and if a payment declines when it finally uploads, the loss is yours, not Shopify's.

Cash and custom payment methods have always worked offline and still do, with no setup at all. Everything sold offline syncs to your Shopify admin automatically once the device reconnects, and there is no extra fee for using offline mode.

Turning on offline card payments

This is the step most merchants miss, and it cannot be done during an outage. Four things must be true before you go offline:

1. Enable it in admin. Point of Sale > Settings > Checkout > "Allow offline payments".
2. Set your two limits. A per-order transaction cap and a per-device daily total. These are your exposure ceiling — choose them deliberately rather than accepting whatever is prefilled.
3. Grant staff the permission. Users need "Accept offline credit and debit payments" or the option will not appear at checkout.
4. Update the app. Offline card payments require Shopify POS 9.14.0 or later.

None of this can be configured without a connection. A store that has not set it up in advance is still cash-only during an outage — which is exactly the situation most merchants discover the hard way.

What works offline, and what doesn't

Offline, a Shopify POS device can:

• Process chip and contactless card payments, if enabled in advance and within your limits
• Process cash transactions
• Accept custom payment methods set up in advance (checks, gift cards, store credit)
• Add products already cached on the device to a cart
• Apply pre-configured discounts
• Print receipts, with a compatible connected printer

It cannot:

• Process Tap to Pay on iPhone or Tap to Pay on Android — these need a connection, which is a meaningful catch if Tap to Pay is your only reader
• Process swiped cards or manual card entry (MOTO)
• Create new products or new customer profiles
• Update inventory across locations in real time
• Process shipping orders or access full reporting

Regional exclusions apply: Interac cannot be processed offline in Canada, eftpos cannot be processed offline in Australia, and offline payments are not available at all for retail locations in France.

The part worth reading twice: you carry the risk

An offline card payment is not authorized at the moment of sale. The device stores it and submits it once you reconnect. If the card is expired, frozen, or has insufficient funds, that payment fails after the customer has walked out with the goods.

Shopify is explicit that recovery is your job: you use the email or phone number captured on the order to chase the customer yourself. There is no chargeback protection and no reimbursement. Shopify recommends reconnecting as soon as possible, ideally within 24 hours, because the longer a batch sits unsubmitted the higher the decline rate.

This is why the two limits matter more than they look. A $50 per-order cap on a device doing $600 of offline trade is a manageable worst case. No cap on a store selling $2,000 furniture is a genuinely bad evening.

Which hardware works offline

The Tap to Pay exclusion deserves emphasis. It is the cheapest way to start taking cards and needs no hardware at all — but it is also the one payment method that stops dead in an outage. If you sell at markets or in a building with unreliable Wi-Fi, keep a physical reader as backup. Our Shopify POS hardware guide covers device-by-device behavior and current pricing.

How Shopify compares to Square here

Square has offered offline card payments longer and is more permissive: a configurable per-transaction cap anywhere from $1 to $50,000, a 24-hour window to keep accepting payments, and up to 72 hours to upload them. As with Shopify, the merchant carries the liability for declines, and Square explicitly will not contact customers on your behalf.

One change worth knowing if you run both systems: Square has said that from April 2026 offline payments will be automatically enabled on all devices unless merchants opt out. Shopify's remains opt-in. If you have Square hardware sitting in a back room, check its settings — you may now be exposed to offline decline risk you never chose.

How to prepare before going offline

• Enable offline payments and set limits — the one step that cannot be done later.
• Preload store data. Open the POS app on a stable connection and browse the catalog. This caches products, pricing, and tax settings on the device.
• Capture contact details. Offline orders are only recoverable if you collected an email or phone number. Make it a habit, not an afterthought.
• Charge everything. A dead tablet stops sales regardless of connectivity. Bring backup power for long events.
• Test hardware while online. Confirm printers, scanners, and drawers connect before the connection drops.
• Add a fallback connection. A mobile hotspot or cellular failover turns an outage into a non-event. For fixed counters, POS Hub's wired connectivity removes Wi-Fi from the equation entirely.
• Brief staff. They need to know offline mode is active, what the caps are, and to collect contact details.

How offline transactions sync

Offline transactions are stored locally on the device. When the connection returns, the app uploads them automatically — updating inventory, recording sales, and reconciling against online orders using timestamps. Each device syncs independently, so if several were used offline, every one needs to reconnect.

If a sync stalls, swiping down on the orders screen usually prompts it. If that fails, confirm the device has a stable signal, then close and reopen the app. Afterwards, check the admin on a desktop and confirm every offline order came through — and specifically review which card payments succeeded. That reconciliation step is the one people skip, and it is where the declines surface.

Frequently asked questions

Does Shopify POS work offline?

Yes. Cash and custom payment methods work offline with no setup. Card payments also work offline, but only if you enabled "Allow offline payments" in your Shopify admin beforehand, set transaction limits, granted staff the permission, and are running POS 9.14.0 or later. Product browsing, discounts, and receipt printing continue to work from cached data.

Can I enable offline card payments on Shopify POS?

Yes — in Shopify admin under Point of Sale > Settings > Checkout > "Allow offline payments". You will also set a per-transaction cap and a per-device daily limit, and staff need the "Accept offline credit and debit payments" permission. It cannot be switched on while offline, so this has to be done in advance.

What happens if an offline card payment declines?

You absorb it. The payment is only authorized when it uploads after you reconnect, so an expired or declined card fails after the customer has left. Shopify does not reimburse or pursue the customer for you — you contact them using the details captured on the order. This is why per-transaction caps matter.

Does Tap to Pay work offline?

No. Tap to Pay on iPhone and Tap to Pay on Android both require a connection and are unsupported offline, as are swiped cards and manual card entry. If Tap to Pay is your only way to take payment, an outage stops card sales completely — keep a Tap & Chip reader as backup.

Are there extra fees for offline mode?

No. Offline functionality is included with Shopify POS at no additional cost. Standard transaction fees apply to offline sales once they sync; there is no offline surcharge.

Can I create new products while offline?

No — adding products requires a connection. A common workaround is to create a few generic placeholder products at set price points before an event, then correct the records once back online.

The bottom line

Offline mode turns an internet outage from a full stop into a manageable inconvenience — but only for stores that set it up in advance. The default state is cash-only, and the settings cannot be changed once the connection is gone.

The honest trade-off is that offline card payments move risk from Shopify to you. For a market stall taking $30 sales, that risk is trivial and the setup is obviously worth doing. For a store with high average order values, cap the per-transaction limit tightly rather than leaving it open. Either way, the decision should be made deliberately on a quiet afternoon, not improvised during a rush.
