Synder pulls every Square transaction: card, cash, refunds, tips, and online orders, into QuickBooks hourly. Choose Per Transaction for individual sale details or Summary Sync for one entry per period or payout. Historical import available.
Synder connects Square alongside Shopify, Stripe, PayPal, Amazon, and 30+ platforms to QuickBooks in one integration – each channel in its own clearing account, revenue never mixed. One setup covers both your Square POS in-person sales and all your online channels.
Synder posts Square activity to a clearing account, then transfers the exact net payout to match your bank deposit. When it hits your bank feed, just click "Match", and everything is done. Cash and pending orders post separately once completed in Square.
Sales, fees, refunds, tips, and Square Capital repayments each post as distinct entries in QuickBooks, so your P&L reflects true revenue and true cost, not net figures.
Square tax amounts map to the correct QuickBooks liability accounts automatically – one account or split by state. Discounts sync as separate line items, keeping gross and net sales always distinct.
Per Transaction sync mode matches Square SKUs to QuickBooks products, updating inventory and COGS per sale, and posting each location to a separate entry; Smart Rules route transactions to the right QuickBooks classes automatically.

I've used Synder in connection with Stripe and Square and I've just started using it with Shopify. While those platforms have their own ways of syncing to QuickBooks, they were always glitchy. With Synder, it’s really easy to go in should something not sync over and see exactly what it was. I really like that it makes problem solving easy, and reconciling at the end of every month much quicker. I’d definitely recommend Synder for anyone who has issues with their current sync software or who is just maybe doing it manually but looking to save time or cross some data entry off their to-do list.
With the QuickBooks Square integration, Synder supports all types of Square sales transactions which are processing and application fees, payouts/settlements, expenses, refunds/chargebacks, adjustments, and multicurrency transactions.
Not a single Square transaction detail is overlooked. Synder records all information provided by the platform, such as item names, customers, taxes, discounts, locations, shipping, gift cards, and tips, directly into your QuickBooks Online account. This ensures that your financial data is comprehensive, accurate, and ready for a seamless accounting and reconciliation process.
Transactions between Square and Intuit QuickBooks Online are typically synced about once an hour. However, it's important to note that the syncing frequency can be influenced by factors such as internet connectivity, server loads, and any potential updates or maintenance activities on either the Square or QuickBooks platforms.
The quick answer will be that it’s probably because your payment is marked as open in Square.
A more detailed answer is that Synder syncs Square payments only when orders are marked as completed in Square. And if an order is still open, it's imported to Synder as pending. This ensures your books remain accurate, as pending orders in Square can be updated or deleted.
Yes! By default, Synder assigns new products to a designated Product Income account in the QuickBooks account specified in the Products/Services settings. However, for gift cards, you might prefer a separate account due to their unique nature.
To set up a liability account for gift cards, follow these steps:
After this setup, newly synced Square gift cards will be automatically linked to the designated Liability account instead of the standard Product Income account.
Synder records Square fees automatically. When a card transaction is synced from Square, Synder creates a separate fee expense line in QuickBooks alongside the sales entry, so the gross sale amount and the Square processing fee appear as distinct items. You control which expense account fees post to via Settings → Mapping in Synder. In the Summary Sync mode, fees appear as a dedicated line in your daily journal entry. In the Per Transaction mode, each transaction includes its own fee expense. No manual entry is needed.
Yes. Synder supports multiple Square locations and maps each one separately in QuickBooks. You can assign different accounts, classes, or tracking categories per location, so revenue and fees from each site are always kept distinct. In the Per Transaction mode, Smart Rules let you automate this routing, for example, posting sales from Location A to one QuickBooks class and sales from Location B to another without any manual sorting after the fact.
Yes, both are supported. Tips collected through Square are synced as a separate line item in QuickBooks, mapped to the account you specify. Cash payments recorded in Square are also synced, though they follow a different flow: since cash doesn't run through Square's processing system, there are no fees, and cash sales don't appear in Square payouts. In Synder, cash transactions are recorded as sales receipts or invoice + payment and mapped to a designated cash or undeposited funds account, then reconciled separately from bank deposits.
Synder handles the core reconciliation flow automatically. All Square activity, like sales, fees, and refunds, is recorded in a Square clearing account in QuickBooks. When Square sends your payout, Synder posts a transfer from that clearing account to your checking account for the exact net payout amount. When that deposit appears in your QuickBooks bank feed, the numbers already match. Click "Match" and the reconciliation is complete. Cash and check transactions are reconciled separately since they don't flow through Square payouts.
Synder pulls the tax amounts recorded in Square and maps them to the liability accounts you specify in QuickBooks. You can assign all sales tax to a single account, or use group-by-region settings to separate tax by state, which is useful if you collect sales tax across multiple locations or jurisdictions. The figures in QuickBooks reflect exactly what Square collected at the point of sale, with no recalculation required on your end.
