Synder review

A connector app that syncs individual transactions for businesses needing maximum data detail.

Verdict

Synder provides a more detailed alternative to summary-based connectors, syncing every individual transaction into the accounting system for maximum granularity. This approach is valuable for businesses that need to track specific customer data in their books, though it can clutter the ledger for high-volume stores.

What customers praise

Synder connects with a wider range of payment gateways (over 25) than many competitors, including Stripe, PayPal, and Square, and offers bill pay features.

What customers criticise

Syncing every single order can create a messy and slow chart of accounts in QuickBooks or Xero for stores with thousands of monthly transactions.

Best for

Sellers who need granular, per-transaction data synced to their books or want to automate accounts payable.
