Top 10 Banking Mistakes to Avoid (MLS 2026)

Banking errors can create confusion throughout the entire accounting system.

Because Banking is tightly integrated with:

•Accounts Payable

•Payroll

•Receivables

•General Ledger

small mistakes can quickly affect:

•balances

•reports

•reconciliation

•financial accuracy

The following are the most common banking mistakes — and how to avoid them.

1. Skipping Bank Reconciliation

The Problem

This is the single most common banking mistake.

Users often:

•enter checks

•enter deposits

•assume balances are correct

•never reconcile the statement

Eventually:

•outstanding checks grow

•balances stop matching

•reports become unreliable

Best Practice

Reconcile every bank statement immediately after it arrives.

2. Editing Checks Without Verifying Totals

The Problem

Changing checks can affect:

•bank balances

•General Ledger totals

•Accounts Payable

•Payroll

Large edits may create inconsistencies if not reviewed carefully.

Best Practice

After editing checks, verify:

•bank totals

•G/L totals

•related accounting modules

3. Deleting Checks Instead of Voiding Them

The Problem

Deleting removes accounting history and weakens your audit trail.

Best Practice

Always:

👉 VOID checks

instead of deleting them.

Void processing preserves:

•history

•numbering

•accountability

4. Forgetting to Post Service Charges and Interest

The Problem

Bank statements include:

•fees

•charges

•earned interest

If these are not entered:

•balances will not match

•reconciliation becomes difficult

Best Practice

Post all:

•service charges

•interest entries

when the statement arrives.

5. Writing Vendor Checks Outside Accounts Payable

The Problem

Some users write vendor checks directly through Banking instead of:

•Accounts Payable

This bypasses:

•aging

•invoice tracking

•vendor balances

Best Practice

Use:

•Accounts Payable Check Processing

for normal vendor payments whenever possible.

6. Ignoring Outstanding Checks

The Problem

Old outstanding checks may indicate:

•lost checks

•duplicate payments

•unreconciled activity

Large outstanding totals distort available cash.

Best Practice

Review the:

•Outstanding Checks Report

regularly.

Investigate old entries immediately.

7. Posting Deposits to the Wrong G/L Account

The Problem

Incorrect G/L postings create:

•inaccurate financial reports

•misleading income totals

•General Ledger imbalances

Best Practice

Always verify:

•Debit account

•Credit account

before saving deposits or charges.

8. Not Printing Registers and Reports

The Problem

Without printed records:

•troubleshooting becomes harder

•audit trails disappear

•historical verification is difficult

Best Practice

Print and retain:

•bank registers

•reconciliation reports

•outstanding checks reports

monthly.

9. Reusing or Changing Check Numbers Improperly

The Problem

Duplicate or altered check numbers can create:

•reconciliation confusion

•audit issues

•tracking errors

Best Practice

Avoid changing check numbers unless absolutely necessary.

Maintain consistent numbering.

10. Waiting Too Long to Correct Banking Errors

The Problem

Small problems become much larger over time.

A missing deposit from:

•yesterday

is easy to fix.

A missing deposit from:

•six months ago

can become a major investigation.

Best Practice

Correct banking discrepancies immediately.

Daily or weekly review prevents major accounting headaches later.
