This is one of the most common issues for new users, and it is almost always fixable. This guide covers the most common causes and how to resolve each one.<\/p>\n<h2>How to Tell If Your Sync Has Paused<\/h2>\n<p>Signs your sync has stopped working:<\/p>\n<ul>\n<li>Transactions stay in &#8220;Ready to Sync&#8221; status and never move to &#8220;Synced.&#8221;<\/li>\n<li>Your accounting software has not received new transactions in days.<\/li>\n<li>You see transactions with &#8220;Failed,&#8221; &#8220;Canceled,&#8221; or &#8220;Deleted&#8221; status in the Platform transactions list.<\/li>\n<li>You received an email notification from Synder about sync issues.<\/li>\n<\/ul>\n<p>To check, go to <strong>Platform transactions<\/strong> in the left-hand menu and look at the sync status column. Click <strong>Explain<\/strong> under any status to see details about what happened.<\/p>\n<h2>Cause #1: Mapping Conflicts (Unmapped Products, Taxes, or Accounts)<\/h2>\n<p><strong>What&#8217;s happening:<\/strong> Synder encountered a transaction with a product, tax rate, or payment method that it could not resolve. This can happen for two distinct reasons:<\/p>\n<ul>\n<li><strong>Setting-based cancellation:<\/strong> The &#8220;Cancel sync if no matching product is found&#8221; setting is enabled, and Synder could not find a matching product in your accounting software.<\/li>\n<li><strong>Product creation failure:<\/strong> Synder tried to auto-create a product in your accounting software but failed \u2014 usually because the product name contains special characters that the accounting API does not support, or because of a temporary API error.<\/li>\n<\/ul>\n<p><strong>How to diagnose:<\/strong><\/p>\n<ul>\n<li>Go to <strong>Platform transactions<\/strong> and look for transactions with &#8220;Failed&#8221; or &#8220;Canceled&#8221; status.<\/li>\n<li>Click <strong>Explain<\/strong> under the sync status \u2014 it will tell you exactly what is missing (e.g., a product that could not be found or created).<\/li>\n<\/ul>\n<p><strong>How to fix:<\/strong><\/p>\n<ul>\n<li>Go to <strong>Settings<\/strong> in the left menu, select your integration at the top.<\/li>\n<li>Navigate to the <strong>Products\/Services<\/strong> tab and set up product mapping to match your platform products to your accounting products.<\/li>\n<li>If the issue is special characters in product names, create the product manually in your accounting software with a clean name, then map it in Synder.<\/li>\n<li>Click <strong>Update<\/strong> at the bottom of the page.<\/li>\n<li>Return to <strong>Platform transactions<\/strong>, select the failed transactions, and choose <strong>Actions \u2192 Sync<\/strong> to re-sync them.<\/li>\n<\/ul>\n<p>To prevent this: Review the <a href=\"https:\/\/synder.com\/help\/synder-settings-checklist-first-sync\/\">Settings Checklist<\/a> to catch configuration gaps before syncing.<\/p>\n<h2>Cause #2: Accounting Software Disconnection<\/h2>\n<p><strong>What&#8217;s happening:<\/strong> The connection between Synder and your accounting software (QuickBooks Online, Xero, or Sage) has expired or been revoked.<\/p>\n<p><strong>How to diagnose:<\/strong><\/p>\n<ul>\n<li>Click the Person icon in the upper-right corner of the page.<\/li>\n<li>Select <strong>Organization settings<\/strong>.<\/li>\n<li>Check the accounting company connection status.<\/li>\n<\/ul>\n<p><strong>How to fix:<\/strong><\/p>\n<ul>\n<li>Disconnect your accounting company and reconnect it from <strong>Organization settings \u2192 Accounting company<\/strong>.<\/li>\n<li>Log in and re-authorize Synder.<\/li>\n<li>Return to <strong>Platform transactions<\/strong>, select the failed transactions, and choose <strong>Actions \u2192 Sync<\/strong>.<\/li>\n<\/ul>\n<p><strong>Why it happens:<\/strong><\/p>\n<ul>\n<li>QuickBooks Online OAuth tokens expire periodically.<\/li>\n<li>Changing your accounting software password breaks existing connections.<\/li>\n<li>Some security settings in your accounting software can revoke third-party access.<\/li>\n<\/ul>\n<h2>Cause #3: Payment Platform Disconnection<\/h2>\n<p><strong>What&#8217;s happening:<\/strong> Your payment platform (Stripe, Shopify, PayPal, etc.) lost its connection to Synder.<\/p>\n<p><strong>How to diagnose and fix:<\/strong><\/p>\n<ul>\n<li>Click the Person icon in the upper-right corner \u2192 <strong>Organization settings<\/strong>.<\/li>\n<li>Look at your connected integrations. If one shows as disconnected, click to reconnect it.<\/li>\n<li>Complete the re-authorization flow.<\/li>\n<li>After reconnecting, go to <strong>Platform transactions<\/strong> and import any transactions that were missed during the disconnection.<\/li>\n<\/ul>\n<h2>Cause #4: API Rate Limits<\/h2>\n<p><strong>What&#8217;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<p><strong>How to diagnose:<\/strong><\/p>\n<ul>\n<li>You will see a <strong>banner notification<\/strong> in the Synder UI alerting you to the rate limit.<\/li>\n<li>Affected transactions will show as &#8220;Canceled&#8221; in <strong>Platform transactions<\/strong>.<\/li>\n<li>Click <strong>Explain<\/strong> under the canceled sync status \u2014 the details will mention the rate limit as the reason.<\/li>\n<\/ul>\n<p><strong>How to fix:<\/strong><\/p>\n<ul>\n<li>Wait 15\u201330 minutes for rate limits to reset automatically.<\/li>\n<li>Sync in smaller batches \u2014 select 25\u201350 transactions at a time instead of hundreds.<\/li>\n<li>Synder will automatically retry after a cooldown period if you are using automatic sync.<\/li>\n<\/ul>\n<h2>Cause #5: Account Deleted or Renamed in Accounting Software<\/h2>\n<p><strong>What&#8217;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.<\/p>\n<p><strong>How to fix:<\/strong><\/p>\n<ul>\n<li>Go to <strong>Settings \u2192 [Your Integration]<\/strong>.<\/li>\n<li>Update the affected mapping to point to an active account or product.<\/li>\n<li>Click <strong>Update<\/strong> to save.<\/li>\n<li>Return to <strong>Platform transactions<\/strong>, select the failed transactions, and use <strong>Actions \u2192 Sync<\/strong>.<\/li>\n<\/ul>\n<h2>Cause #6: Insufficient Mappings for Summary Sync<\/h2>\n<p><strong>What&#8217;s happening:<\/strong> If you are using Summary Sync mode, all required mappings must be complete before any transactions can sync. A single missing mapping will block the entire batch.<\/p>\n<p><strong>How to fix:<\/strong> Complete all required mappings in your settings, or <a href=\"https:\/\/synder.com\/contact\/\">contact Synder support<\/a> for assistance \u2014 Summary Sync settings changes may require help from the Synder team.<\/p>\n<h2>Cause #7: Plan Migration Locks Auto-Sync<\/h2>\n<p><strong>What&#8217;s happening:<\/strong> You recently migrated from a Large or Scale plan to the Pro plan. During plan migration, auto-sync is automatically paused and requires manual re-activation.<\/p>\n<p><strong>How to diagnose:<\/strong><\/p>\n<ul>\n<li>Check your plan status under the Person icon \u2192 <strong>Organization settings<\/strong>.<\/li>\n<li>Look for a banner or notification about plan migration.<\/li>\n<li>Auto-sync toggle may appear enabled but is actually locked pending onboarding.<\/li>\n<\/ul>\n<p><strong>How to fix:<\/strong><\/p>\n<ul>\n<li>Book your onboarding call with your assigned CSM \u2014 they will unlock auto-sync after reviewing your configuration.<\/li>\n<li>Alternatively, email <a href=\"mailto:help@synder.com\">help@synder.com<\/a> and mention your plan migration to request manual unlock.<\/li>\n<li>In the meantime, you can still sync transactions manually from <strong>Platform transactions \u2192 Actions \u2192 Sync<\/strong>.<\/li>\n<\/ul>\n<h2>Cause #8: Synder Auto-Disables After Repeated Failures<\/h2>\n<p><strong>What&#8217;s happening:<\/strong> Synder has a safety mechanism that automatically disables auto-sync after a series of consecutive sync failures. This prevents your account from accumulating a large backlog of failed transactions.<\/p>\n<p><strong>How to diagnose:<\/strong><\/p>\n<ul>\n<li>You may have received an email from Synder notifying you that auto-sync was disabled.<\/li>\n<li>Check the auto-sync toggle in Settings \u2014 it may be turned off even though you did not disable it manually.<\/li>\n<li>Look at recent transactions in <strong>Platform transactions<\/strong> \u2014 you will likely see a pattern of consecutive failures.<\/li>\n<\/ul>\n<p><strong>How to fix:<\/strong><\/p>\n<ul>\n<li>Fix the underlying issue first \u2014 resolve whatever caused the consecutive failures (usually a mapping issue, disconnection, or account change).<\/li>\n<li>Re-sync the failed transactions manually to confirm the fix works.<\/li>\n<li>Re-enable auto-sync in <strong>Settings \u2192 your integration \u2192 Auto-Sync toggle<\/strong>.<\/li>\n<li>Monitor for the next few hours to confirm auto-sync stays active.<\/li>\n<\/ul>\n<h2>General Troubleshooting Steps<\/h2>\n<ul>\n<li>Go to <strong>Platform transactions<\/strong> in the left menu.<\/li>\n<li>Filter by status: look for &#8220;Failed,&#8221; &#8220;Canceled,&#8221; or &#8220;Deleted&#8221; transactions.<\/li>\n<li>Click <strong>Explain<\/strong> under the sync status of any problematic transaction.<\/li>\n<li>Follow the guidance in the Explain details \u2014 it often includes a direct link to the relevant help article.<\/li>\n<li>After fixing the issue, select the transactions and choose <strong>Actions \u2192 Sync<\/strong>.<\/li>\n<\/ul>\n<p>For a full list of sync statuses and what they mean, see <a href=\"https:\/\/synder.com\/help\/transaction-management-per-transaction-sync-statuses-and-what-they-mean\/\">Sync Statuses Explained<\/a>.<\/p>\n<h2>Need Help?<\/h2>\n<p>If you have tried the steps above and your sync is still pausing, <a href=\"https:\/\/synder.com\/contact\/\">reach out to the Synder support team<\/a> via chat or email.
