Is your Synder sync pausing unexpectedly \u2014 or did you get an email from Synder saying auto-sync was turned off<\/strong>? This is one of the most common issues for new users, and it is almost always fixable. If you are not sure which setting is wrong<\/strong>, click the Explain<\/strong> button under any failed transaction \u2014 it tells you exactly what Synder could not resolve \u2014 then find the matching cause below. This guide covers the most common causes and how to resolve each one.<\/p>\n Signs your sync has stopped working:<\/p>\n To check, go to Platform transactions<\/strong> in the left-hand menu and look at the sync status column. Click Explain<\/strong> under any status to see details about what happened.<\/p>\n What’s happening:<\/strong> Synder encountered a transaction with a product, tax rate, or payment method that it could not resolve. The visible symptom is usually transactions landing in a Canceled<\/strong> status \u2014 when a required account, tax, or product is not available, Synder cannot build an accurate transaction, so it cancels it and, after repeated cases, pauses the sync. This can happen for two distinct reasons:<\/p>\n How to diagnose:<\/strong><\/p>\n How to fix:<\/strong><\/p>\n To prevent this: Review the Settings Checklist<\/a> to catch configuration gaps before syncing.<\/p>\n Seeing lots of Canceled<\/strong> transactions? That is the same root cause \u2014 see Common Sync Errors and How to Fix Them<\/a> for fixing them in bulk.<\/p>\n What’s happening:<\/strong> The connection between Synder and your accounting software (QuickBooks Online, Xero, or Sage) has expired or been revoked.<\/p>\n How to diagnose:<\/strong><\/p>\n How to fix:<\/strong><\/p>\n Why it happens:<\/strong><\/p>\n What’s happening:<\/strong> Your payment platform (Stripe, Shopify, PayPal, etc.) lost its connection to Synder.<\/p>\n How to diagnose and fix:<\/strong><\/p>\n What’s happening:<\/strong> Your accounting software limits how many API requests can be made per minute or hour. Syncing a large batch of transactions can hit this limit.<\/p>\n How to diagnose:<\/strong><\/p>\n How to fix:<\/strong><\/p>\n What’s happening:<\/strong> An account, product, or tax code in your accounting platform was renamed or deleted after you set up the mapping in Synder. Synder can no longer find the target, so syncs fail. This often affects a category account<\/strong> you chose in your Synder settings \u2014 such as a Fees\/Expenses<\/strong>, Sales<\/strong>, Clearing<\/strong>, or payout “Transfer to”<\/strong> bank account. It can also happen if the account’s type was changed to an incompatible type, or if no account is mapped for a specific currency. When auto-sync turns off after one of these changes, this is usually the setting to check.<\/p>\n How to fix:<\/strong><\/p>\n What’s happening:<\/strong> If you are using Summary Sync mode, all required mappings must be complete before any transactions can sync.
