Troubleshooting in Synder helps you see how your data is flowing and catch problems early. In Per Transaction mode, it brings together three tabs: Synchronization issues, Import activity log, and Sync speed. Use it to fix sync errors in bulk, review what Synder imported, and understand how quickly your data moves into your books.
Open Troubleshooting from the left-hand menu.
Synchronization issues
The Synchronization issues tab groups failed and canceled transactions by their error message, so you can fix a whole group at once instead of opening transactions one by one.
Each row shows:
- Quantity — how many transactions share the same error.
- Status — for example, Canceled or Failed.
- Error message — the reason the transactions did not sync.
- Actions — See related transactions opens a pre-filtered list of the affected transactions so you can resolve and resync them together.
Use the Search, Status, and Date range filters at the top to narrow the list, then click Apply (or Reset filters to clear them). Search requires at least 3 characters.
Sync errors vs. transactions that have not synced yet
These two look similar but need different actions:
- A sync error is a transaction Synder tried to sync and could not — it shows as Failed or Canceled in the Synchronization issues tab, with an error message (for example, a closed accounting period, a rejected payment, or a missing product). Fix the cause, then roll back and re-sync.
- A transaction that has not synced yet is not an error at all — Synder is intentionally waiting. The most common case is a draft or pending invoice (for example, a Stripe invoice that is not finalized). These do not sync until they are finalized; you can leave them, or archive them on the platform if they are not needed.
Quick check: if it is in the Synchronization issues tab with an error, it is an error — fix it. If it is simply not in your books yet and has no error, it is waiting on the platform. For closed-period and draft-invoice specifics, see Common Sync Errors and How to Fix Them.
If your sync keeps pausing, see Why Your Synder Sync Keeps Pausing.
Import activity log
The Import activity log shows the list of imports from your connected integrations into Synder. Use it to confirm what was imported, when, and whether each import finished. For a breakdown of what each import type means, see the in-app guide of import types.
Each row shows:
- Request date — when the import was requested.
- Import from / Import to — the date range the import covered.
- Integration — the connected account the data came from.
- Imported — how many transactions were imported.
- Initiated by — for example, System (auto-import) or a manual request.
- Type — for example, Hourly or Postponed.
- Import status — for example, Finished.
Filter by Request date, Import from/to, Integration, Initiated by, Import status, Type, or Import ID, then click Apply. To pull in older data, use Import historical data.
Sync speed
The Sync speed tab helps you get a grasp of how quickly synchronization happens. It presents two graphs:
- Transaction volume by platform — how many transactions moved through Synder over time, broken down by integration.
- Sync time process breakdown — the average time each sync step takes, so you can see where time is spent (for example, queries to the payment integration, Synder internal processing, and querying or posting to your accounting system).
Each graph has its own filters — time range (for example, 7 days), grouping (for example, Day), integrations, and status or process group — with Apply and Reset filters controls. Turn on Display detailed processes on the second graph to see a finer breakdown.
