Real Customer Questions
Potomac Selections:
"Since we must mark all payments received through Masava, how should we record check returns for insufficient funds? We will also need to apply our insufficient funds fee to the invoice?"
Potomac Selections:
"Can you remind me how I can delete a payment applied toward an invoice? When entering a payment for multiple invoices, I didn't realize the total didn't match our system and need to remove a deposit for one of the invoices."
Reversing a Payment
Step 1: Locate the Payment
Navigate to the invoice with the incorrect payment
Open the invoice detail page
Find the payment in the Transaction History section
Note the payment details (amount, date, check number)
Step 2: Delete/Reverse the Payment
Locate the payment row in transaction history
Click the "..." menu (three dots) or "Actions" button next to the payment
Select "Delete Payment" or "Reverse Payment"
Confirmation dialog appears
Step 3: Enter Reversal Reason
Important: Most systems require you to select a reason for audit purposes.
Common reasons:
NSF / Bounced Check (most common)
Applied to Wrong Invoice
Incorrect Amount
Customer Dispute
Bank Error
Stop Payment
Other (with notes)
Select the appropriate reason and add notes explaining the situation.
Example notes:
"Check returned NSF by bank on 03/15/2026"
"Accidentally applied Customer A's payment to Customer B's invoice"
"Entered $1,000 instead of $100.00 - decimal error"
Step 4: Confirm Reversal
Review the reversal details
Click "Confirm" or "Delete Payment"
System processes the reversal
What Happens After Reversal
✅ Invoice balance increases back to unpaid amount
Balance before reversal: $0.00 (if paid in full)
Balance after reversal: Full invoice amount
✅ Payment removed from transaction history
Payment no longer shows on invoice
Reversal note recorded in audit log with your name and timestamp
✅ QuickBooks payment deleted (if already synced)
System automatically removes payment from QuickBooks
Usually happens within a few minutes
Check integration push log to confirm
✅ Optional customer notification (if configured)
Some organizations notify customers of payment reversals
Check with administrator about notification settings
✅ Audit trail maintained
Reversal recorded with date, time, user, and reason
Original payment details preserved in system logs
Cannot be undone (must re-record payment if mistake)
Handling NSF Checks (Complete Workflow)
NSF = Non-Sufficient Funds = Check bounced due to insufficient money in customer's account.
Overview of NSF Process
Bank notifies you check bounced
Reverse the payment in Masava
Add NSF fee to customer account
Contact customer for new payment
Record new payment when received
Consider changing payment terms (COD) if repeat offender
Step 1: Receive NSF Notification from Bank
You'll typically receive:
Bank notification (email, phone, or mail)
NSF date (when check was returned)
Bank's NSF fee (charged to you by bank)
Returned check or image
Record this information:
Date of NSF
Your bank's NSF fee (typically $25-$35)
Check number
Customer name
Invoice number(s) affected
Step 2: Reverse the Original Payment
Follow the Reversing a Payment steps above:
Locate the invoice with the NSF payment
Delete/reverse the payment
Select reason: "NSF / Bounced Check"
Add detailed notes:
"Check #4821 returned NSF on 03/15/2026"
"Bank NSF fee: $35.00"
"Customer NSF fee to be charged: $50.00"
Confirm reversal
Result: Invoice balance restored to unpaid amount
Step 3: Add NSF Fee to Customer Account
Now you need to charge the customer for the NSF check.
Your organization determines:
NSF fee amount (typically $25-$75)
How to apply fee (varies by organization)
Option A: Add Line Item to Original Invoice
If your system allows editing delivered invoices:
Navigate to the original invoice
Click "Edit" or "Reopen Invoice"
Add line item:
Product/Description: "NSF Fee - Check #4821"
Quantity: 1
Unit Price: $50.00 (or your organization's fee)
Total: $50.00
Save invoice
New invoice total: Original amount + NSF fee
Example:
Original invoice: $1,247.53
NSF fee: $50.00
New total: $1,297.53
Option B: Create Separate NSF Fee Invoice
Most common method:
Navigate to Orders → New Order
Select the customer
Add line item:
Product/Description: "NSF Fee - Check #4821 on Invoice 136001"
Quantity: 1
Unit Price: $50.00
Total: $50.00
Add order note referencing original invoice
Deliver immediately (so it can be paid)
Result: Separate invoice for $50.00 NSF fee
Option C: Add to Customer's Next Invoice
If customer has regular orders:
Wait for customer's next order
Add NSF fee as line item on that order
Note: "NSF Fee from Check #4821"
Note: This delays collection of NSF fee until next order.
Step 4: Update Invoice Total
After adding NSF fee (any method), customer now owes:
Method A (line item added):
Original invoice amount + NSF fee
Method B (separate invoice):
Original invoice amount (on original invoice)
NSF fee (on new invoice)
Method C (next invoice):
Original invoice amount (on original invoice)
Next order amount + NSF fee (on next invoice)
Step 5: Contact Customer
Notify customer immediately about:
Check bounced
Original invoice unpaid again
NSF fee added
Total amount now due
Request new payment method
Sample communication:
Consider payment term changes:
Require COD for next few orders
Require payment in advance
Reduce credit limit
More frequent payments
Step 6: Record New Payment
When customer provides new payment:
Verify new payment clears before recording (for checks)
Record payment on original invoice
Record payment on NSF fee invoice (if separate)
Use new check number or different payment method
Add note: "Replacement payment for NSF check #4821"
Example payment entry:
NSF Fee Best Practices
✅ Have clear NSF fee policy

Typical range: $25-$75
Be aware of state laws on NSF fees
✅ Track repeat NSF customers
Note in customer account
Consider payment term changes
May require prepayment if chronic issue
✅ Document everything
Bank notification
NSF date
Fees charged
Customer communications
New payment details
⚠️ Don't apply new payment until cleared
Wait for checks to clear
Verify electronic payments completed
Consider requiring wire transfer or certified check
Moving Payments Between Invoices
Scenario: Payment was applied to wrong invoice by mistake.
Real Customer Issue:
"Can you remind me how I can delete a payment applied toward an invoice? When entering a payment for multiple invoices, I didn't realize the total didn't match our system and need to remove a deposit for one of the invoices."
Steps to Move Payment
Reverse payment from incorrect invoice:
Follow Reversing a Payment steps above
Select reason: "Applied to Wrong Invoice"
Add note: "Payment belongs on Invoice #XXXXX"
Navigate to correct invoice:
Find the invoice where payment should be applied
Verify this is the correct invoice
Record payment on correct invoice:
Click "Record Payment"
Use same payment details:
Same payment method
Same check number
Same amount
Same date (or close to it)
Add note: "Moved from Invoice #XXXXX - originally entered incorrectly"
Verify both invoices:
Original invoice: Balance increased (payment removed)
Correct invoice: Balance decreased (payment applied)
Both invoices have notes explaining the transfer
Common Reasons for Moving Payments
Bulk payment allocation error:
Entered individual payments instead of bulk payment
Allocated to wrong invoices in bulk payment
Customer provides corrected allocation after payment
Similar customer names:
"Smith Restaurant" vs "Smith's Diner"
Applied to wrong Smith account
Multiple invoices mixed up:
Invoice 136001 vs 136010
Transposed numbers
Partial payment applied to wrong invoice:
Had 3 unpaid invoices
Applied to newest instead of oldest
Need to move to oldest per customer request
QuickBooks Considerations
Automatic Sync of Reversals
When you reverse a payment in Masava:
✅ Payment automatically deleted from QuickBooks
System sends delete command to QuickBooks
Usually processes within 5-10 minutes
Check integration push log to confirm
✅ Invoice returns to unpaid in QuickBooks
Balance restored in both systems
Aging calculations updated
Timing Considerations
Best practice: Check with accounting before reversing old payments
Why:
Accounting periods may be closed in QuickBooks
Month-end reconciliation may be complete
May need accountant to manually adjust
General rule:
Same month: Usually fine to reverse
Prior month: Check with accounting first
Prior quarter: Definitely check with accounting
Bank Reconciliation Impact
After payment reversal:
Bank reconciliation in QuickBooks will show:
Original deposit (with NSF check)
NSF reversal/adjustment from bank
These should match and balance out
Accountant will:
Mark original check as NSF in reconciliation
Record bank's NSF fee
Adjust reconciliation accordingly
Best Practices
NSF Prevention
✅ Know your customers
Track payment history
Note any previous NSF incidents
Adjust terms for risky customers
✅ Require prepayment or COD for new customers
Until payment history established
Reduce NSF risk
Standard practice in alcohol distribution
✅ Set reasonable credit limits
Don't extend too much credit
Monitor aging receivables
Adjust limits based on payment behavior
✅ Verify large checks before delivery
Call bank to verify funds (for very large amounts)
Consider requiring certified check or wire
Risk management for high-value orders
NSF Response
✅ Act quickly when NSF occurs
Reverse payment immediately
Contact customer same day
Add NSF fee promptly
✅ Document thoroughly
Bank notification
All communications with customer
NSF fee rationale
Payment term changes
✅ Be consistent with policies
Apply NSF fees uniformly
Follow same process each time
Document policies in writing
✅ Maintain professional communication
Be firm but courteous
Explain fees clearly
Offer payment options
⚠️ Don't accept another check immediately
Require certified check, wire, or COD
Wait for replacement check to clear
Consider payment plan if needed
⚠️ Don't continue extending credit
Hold future orders until paid
Change to COD terms
Reduce credit limit
Troubleshooting
Cannot Delete Payment
Problem: Delete button disabled or error message
Check: ✓ Do you have permission to delete payments? ✓ Is payment synced to QuickBooks and locked? ✓ Is accounting period closed? ✓ Is payment part of closed transaction?
Solutions:
Permission issue: Contact administrator to grant permission
QuickBooks locked: Ask accounting to unlock period
Period closed: May need accountant to manually adjust in QuickBooks
Payment Reversal Not Syncing to QuickBooks
Problem: Reversed in Masava but still showing in QuickBooks
Check: ✓ Is QuickBooks integration active? ✓ Check integration push log for errors ✓ How long has it been? (May take up to 15 minutes)
Solutions:
Wait a bit longer for sync
Check integration status
Try manual sync if available
Contact support if still not syncing
