Serverless Sync™

With Serverless Sync™ you can open a check on one register that uses, Inc.’s BackOffice servers and continue it on another. Checks stay in sync as long as your iPads stay on the same WiFi network.

Before You Start

To ensure your system seamlessly handles Serverless Sync, we recommend that you follow these 4 steps:

  1. Update all registers to the latest version of ShopKeep.

    All registers must be on the same version of ShopKeep for Serverless Sync to work.

  2. Use the latest iPad hardware available from Apple.

    In some high-volume environments, iPad 4’s (and earlier devices, including the iPad Mini) may experience significant issues. This may include checks not syncing, serious register lag, and speed issues. For best performance, use iPad Airs or later for all of your registers.

  3. Set up a dedicated WiFi router.
    • The WiFi router must stand alone from the modem. DO NOT use a modem/router combo box.
    • Don’t use shared or “public” Wi-Fi networks (like in a mall or government building). Instead, set up a dedicated wireless network for your registers.
    • Don’t use a combination modem/router device. If you have one of these, put it in “bridge” mode and connect it to a dedicated router.
    • Ensure that all of your ShopKeep registers are within 30 feet of your Wi-Fi router.
    • Do not use Wi-Fi repeaters or range extenders.
    • Ensure there is sufficient wireless signal strength to reach all of your ShopKeep Registers.
    Check out our Best Practices for Network Setup article for other networking recommendations.
  4. Operate no more than 4 registers in one location with Serverless Sync.

    This is our recommendation, but not a specific requirement. With more that four registers, you run the risk of more difficult troubleshooting and increased syncing / networking issues.

Using Serverless Sync

Serverless Sync shares all your saved checks across your iPads that use, Inc.’s BackOffice servers. You can Split, Merge, and Transfer Checks as usual.

  1. Sign in to your registers as a Manager.
