The "Integration Status" on the main home page shows the current status of the integration between AutoEntry and your accounts package. It does not mean though that AutoEntry needs to be disconnected and reconnected (integrated) from your accounts package, or that the integration has failed. There will be a reason below the 'barred' icon as to why an error has occurred. Generally, the integration status will be ok as below displaying the correct tick icon:
Some accounts packages also show the client you have connected to as above.
The most common reason for the barred icon appearing is if AutoEntry tried to publish invoices through to the integrated accounts package but some invoices couldn't publish. In this case, AutoEntry tried to publish 1 invoice to Xero but it failed to publish.
If an invoices fails to Publish there will be a red exclamation triangle beside that invoice that you can click on to see the error.
If the integration has reset in the background for any reason and an 'Access Token' error appears, this can be resolved by a quick disconnect and re-connect of AutoEntry with your accounting software. Changing a username or password in your accounts package can also break the connection between AutoEntry and your accounts package which can also prompt the barred icon.
If you have newly integrated with Sage 50 and are seeing this icon, this is usually just indicating that your Sage data has not synced yet. To resolve this, just resync your data.
