When Rundoo won't load, disconnects you mid-sale, or starts feeling sluggish, it's almost always a network or browser issue — not Rundoo itself. This Rundoc walks through the quick checks you can run at the register, then answers the connectivity questions we hear most often.

Rundoo runs entirely in your browser and talks to our servers constantly — every sale, every cart change, every lookup. That means a weak wifi signal or a tab that's been open for three days can masquerade as "Rundoo is broken." There's no single UI surface for connectivity — if something feels off, the Support button in the top-right of the header (next to the search button) is the fastest way to reach us while you work through the ladders below.

Rundoo won't load at all

You open Rundoo and get a blank page, a spinner that never finishes, or a "can't reach this site" message. Work the ladder in order.

  1. Check your wifi or internet. Look at the wifi icon on your computer — is it connected? Open a different site like google.com in a new tab. If that doesn't load either, the problem is your internet, not Rundoo. Restart your router (unplug it for 30 seconds, plug it back in, wait two minutes for it to come back up). If you're on store wifi and other devices are also offline, call your internet provider.
  2. Refresh the tab. Hard refresh with Cmd+Shift+R on Mac or Ctrl+Shift+R on Windows — that clears a stale page out of the browser's memory and reloads fresh. A regular refresh is fine too, but hard refresh is more thorough.
  3. Try a new tab. Close the Rundoo tab, open a brand-new one, and go to app.rundoo.app. Tabs that have been open for a long time can get into weird states that a fresh tab fixes in one step.
  4. Try a different browser. If you normally use Chrome, open Safari or Edge and sign in there. If Rundoo loads in the other browser, the issue is with your usual browser's cache or an extension — clearing your cache usually does it.
  5. Check if Rundoo itself is down. See the "Is Rundoo down or is it just me?" section below. If our status page shows an incident, you're not doing anything wrong — we're on it.

I got disconnected mid-sale

You were ringing up a customer and the page locked up, showed a banner, or went blank. Breathe — you probably didn't lose the sale.

  1. Don't close the tab yet. If the cart is still on screen, your items are still there in the browser's memory. Wait 10–15 seconds to see if the connection recovers on its own; Rundoo will reconnect and sync the cart when it does.
  2. Check the wifi signal. Glance at the wifi icon on your computer. If it's dropped to one bar or disconnected entirely, that's your answer — the sale didn't fail, your network did. Move closer to the router if you can, or switch to a wired connection at the counter.
  3. Refresh the page. If the connection is back but the page still feels stuck, refresh the tab. Any sale you hadn't submitted yet is gone — you'll need to re-ring it. Any sale you'd already tapped Sale on made it to our servers before the disconnect, and you'll find it in the POS > Transactions > Completed tab.
  4. If the customer is still waiting, save what you can as a draft the next time the page comes back (tap Save draft on the action cluster), so you don't lose the cart if it disconnects again. Pull the draft back up from the POS > Transactions > Drafts tab to finish the sale.
  5. If disconnects keep happening, your wifi is the culprit — call your IT person or internet provider. One blip is normal; three in an hour is a signal problem worth fixing.

Sale is saving slowly

The progress spinner on Sale takes a long time, or the page feels laggy when you're adding products to the cart. This is almost always a network speed issue, not Rundoo.

  1. Run a speed test. Go to fast.com or speedtest.net in a new tab. Rundoo runs comfortably on anything above 5 Mbps down / 1 Mbps up. If you're seeing less than that, your connection is the bottleneck.
