What Should I Do if a Square Payment Is Marked as Pending in Synder? Square Pending Transaction Explained

This guide helps you resolve Square payments stuck in a pending status in Synder. If your Square orders show as pending, follow the steps below to fix them and keep your books accurate.

What This Article Does Not Cover

This guide does not cover:

• How to reconcile already synced Square transactions in Synder.
• Issues unrelated to order status (e.g., failed payments, refunds).
• Advanced Square or Synder features outside of order completion and syncing.

Why Payments Appear as Pending in Synder

Synder syncs Square payments only when Square marks the order status as completed.

• If an order in Square is open, new, or not completed, Synder imports it as pending.
• This is by design. Square can still change or delete pending orders. Synder waits for the final status to keep your accounting records accurate.
• A Square order may already contain a payment (tender), but Synder does not sync it until Square marks the order status as Completed.

How to Resolve Pending Square Payments

To move pending orders to completed and sync them properly, follow these steps:

Find the pending order

• First, open Synder and look for the order marked as pending.
• In Square, this same order will show an open, new, or other non-completed status.

Log into Square

• Go to your Square account. Select Orders from the left-hand menu.

Complete the order

• Click the three dots next to the order.
• Select Mark Picked Up.
• The order status in Square changes to Completed.

Once the order is marked as Completed in Square, here is what happens:

• If Auto-sync is enabled for your Square account in Synder, the pending payment will automatically sync.
• If Auto-sync is disabled, the transaction is released for sync within 24–48 hours.

Don’t worry — any transactions already in Synder won’t be duplicated during this process.

A More Automated Resolution

Additionally, if your Square setup requires frequent manual updates to order statuses, we offer a custom configuration that allows syncing any order as long as a payment (tender) is present.

What to Do if You Cannot Find the Pending Order in Square 

However, in some cases the pending order shown in Synder no longer exists in Square.

You may notice that:

• Clicking the Square order link in Synder opens an error message in Square
• The order cannot be found in Square search or Orders

Why This Happens 

• If Square edits an order or adjusts its details, it automatically creates a new order and deletes the old one.
• The same happens when the initial payment fails and Square processes a second attempt successfully.

As a result, the old Square order stays stuck in Pending in Synder while the new one syncs. This is expected — it reflects how Square manages order updates internally.

How to Handle Stuck Pending Orders 

If the original pending order no longer exists in Square, you can archive the outdated transaction in Synder. You have two options for archiving it:

Option 1: Archive Transactions Manually 

To prevent clutter in Platform Transactions and avoid unnecessary pending entries in your summaries, use the Archive feature. To manually archive orders:

1. Open the platform transactions in Synder 
2. Select the unnecessary pending transactions 
3. Click Actions dropdown
4. Click Archive

See this guide for more details on the Archive feature.

Option 2: Archive Pending Transactions Automatically 

Alternatively, you can enable the Synder feature that automatically archives pending transactions if a Square order stays pending for longer than a set number of days.

1. Access settings from the left-side menu
2. In General tab, enable Archive Pending transactions after set number of days 
3. Choose the desired number of days
4. Click Update

Note: Set a long enough timeframe to avoid archiving legitimate pending Square orders that may still complete later. Choose the number of days based on your normal payment processing turnaround time.
