Why Every Accountant Needs a Bank Statement Glossary
Bank statement terminology trips up even experienced accountants when dealing with unfamiliar banks or international clients. A Chase statement uses different labels than a Barclays statement. A Canadian bank statement from CIBC formats transaction codes differently than an American statement from Wells Fargo. Understanding every field, code, and abbreviation eliminates confusion during bank reconciliation and data entry.
This glossary covers 40+ terms across six categories. Whether you are a CPA handling multi-client bank statement processing, a bookkeeper doing monthly reconciliation, or a finance professional converting statements to Excel, these definitions and examples give you the reference you need.
When you are ready to convert bank statements to accounting-ready formats, Zera Books handles the extraction automatically — processing any bank format with 99.6% accuracy and exporting to Excel, CSV, QBO for QuickBooks, IIF, or OFX at $79/month unlimited.
Statement Structure & Fields
Statement Period
The date range a bank statement covers, typically one calendar month. The period defines the opening balance date and closing balance date for all listed transactions.
Example: A statement period of January 1–31, 2025 includes every transaction that posted between those dates. Overlapping periods across accounts can cause duplicate entries during reconciliation.
Opening Balance
The account balance at the start of the statement period. Equal to the closing balance of the previous statement. Used as the starting point for all running balance calculations.
Example: If your December statement closed at $14,250.00, your January statement opens at $14,250.00. A mismatch between these figures signals a gap in statement coverage.
Closing Balance
The account balance at the end of the statement period. Calculated as opening balance plus all credits minus all debits during the period.
Example: Opening balance of $14,250 plus $8,000 in deposits minus $6,300 in withdrawals equals a closing balance of $15,950.
Running Balance
The cumulative account balance after each transaction. Shows exactly how much was in the account at any point during the statement period. Not all banks include this field.
Example: After a $200 debit from a balance of $5,000, the running balance shows $4,800. The next line shows a $1,500 deposit bringing it to $6,300.
Account Number
The unique identifier assigned to a specific bank account. Appears at the top of every statement. For multi-account statements, each section has its own account number.
Example: A business may have checking (****4521), savings (****7803), and credit card (****9156) accounts, each with separate statement sections.
Sort Code (UK) / Routing Number (US)
A bank identification number used for transaction routing. Sort codes (6 digits, UK format: XX-XX-XX) and routing numbers (9 digits, US format: XXXXXXXXX) identify the specific branch.
Example: Barclays sort code 20-17-68 identifies a specific branch. Wells Fargo routing number 121042882 identifies their California processing center.
IBAN (International Bank Account Number)
A standardized international account number format used across 80+ countries. Combines country code, check digits, bank code, and account number. Appears on statements for accounts that handle international transfers.
Example: A UK IBAN like GB29 NWBK 6016 1331 9268 19 contains the country (GB), check digits (29), bank code (NWBK), sort code (601613), and account number (31926819).
Transaction Types & Codes
Debit (DR)
Money leaving your account. On a bank statement, debits include payments, withdrawals, transfers out, and fees. Shown as negative amounts or in a dedicated debit column.
Example: A $150 electric bill payment appears as a debit of $150.00. Your running balance decreases by $150.
Credit (CR)
Money entering your account. On a bank statement, credits include deposits, transfers in, interest earned, and refunds. Shown as positive amounts or in a dedicated credit column.
Example: A client direct deposit of $3,500 appears as a credit. Your running balance increases by $3,500.
ACH (Automated Clearing House)
An electronic funds transfer processed through the ACH network. Common for payroll direct deposits, recurring bill payments, and vendor payments. Typically settles in 1–2 business days.
Example: A payroll deposit labeled "ACH CREDIT - ACME INC PAYROLL" means your employer sent the payment electronically through the ACH network.
Wire Transfer
A direct bank-to-bank electronic transfer that settles the same day. More expensive than ACH ($15–$45 per transfer) but immediate. Used for large or time-sensitive payments.
Example: A real estate closing payment of $250,000 sent via wire transfer appears with a reference number and the receiving bank details.
EFT (Electronic Funds Transfer)
A broad term covering any electronic movement of money between accounts. Includes ACH, wire transfers, debit card transactions, and online bill payments. Most modern bank transactions are EFTs.
Example: Your phone bill auto-pay labeled "EFT DEBIT - VERIZON WIRELESS" is an electronic funds transfer initiated by Verizon.
NSF (Non-Sufficient Funds)
A returned check or payment because the account lacked funds to cover it. The bank charges an NSF fee (typically $25–$35) and the original payment does not process.
Example: A check you wrote for $800 bounces because the account only had $600. The statement shows "NSF - CHK #1045" plus a $34 NSF fee.
POS (Point of Sale)
A debit card transaction processed at a physical merchant terminal. Appears on statements with merchant name, location, and sometimes a reference number.
Example: "POS DEBIT - STAPLES #0412 VANCOUVER BC" indicates a debit card purchase at Staples store #412.
ATM Withdrawal
Cash withdrawn from an automated teller machine using a debit card. Shows the ATM location and may include surcharge fees from out-of-network machines.
Example: "ATM WDL - 1234 MAIN ST" with a $200 debit plus a $3.50 non-network surcharge fee on a separate line.
Service Charge / Monthly Fee
Recurring fees the bank charges for account maintenance. May include monthly service fees, paper statement fees, minimum balance penalties, or overdraft protection fees.
Example: "MONTHLY SERVICE CHARGE" with a $12.95 debit. Some banks waive this with a minimum balance or direct deposit.
Reconciliation & Processing
Bank Reconciliation
The process of comparing your accounting ledger against your bank statement to verify all transactions match. Identifies discrepancies like missing entries, duplicates, timing differences, and unauthorized charges.
Example: Your books show $15,200 cash, but the bank statement shows $14,800. Reconciliation reveals a $400 check that cleared the bank but was not recorded in your books.
Outstanding Check
A check you have written and recorded in your books but that has not yet cleared the bank. A common reconciling item that explains why your book balance differs from your bank balance.
Example: You wrote check #1089 for $500 on January 28. By the January 31 statement cutoff, the payee had not deposited it. This $500 outstanding check is a reconciling item.
Deposit in Transit
A deposit you have recorded in your accounting system but that does not appear on the current bank statement. Usually occurs when deposits are made near the end of a statement period.
Example: You deposited $2,400 on January 31 after the bank cutoff time. Your books show it, but it appears on the February statement instead.
Cleared Transaction
A transaction that has been fully processed and posted to the bank statement. The funds have moved and the transaction is final. Cleared transactions are matched during reconciliation.
Example: An ACH payment of $750 initiated on Monday shows as "pending" on Tuesday and "cleared" on Wednesday when it appears on the statement.
Unreconciled Difference
The remaining dollar amount that does not match after accounting for all known reconciling items. An unreconciled difference of zero means reconciliation is complete. A non-zero difference requires investigation.
Example: After matching all transactions, your reconciliation shows a $17.50 difference. Investigation reveals a bank fee you forgot to record.
Void Transaction
A transaction that was cancelled before it fully processed. On a bank statement, voided transactions typically do not appear. In your accounting system, voided entries remain for audit trail purposes.
Example: You void check #1092 because you wrote the wrong amount. Your ledger marks it void but the bank statement has no record since it was never deposited.
Conversion Formats & Output Types
CSV (Comma-Separated Values)
A plain text file format where data values are separated by commas. The most universal import format accepted by virtually all accounting software including QuickBooks, Xero, Sage, and Wave.
Example: A CSV bank statement line: "01/15/2025,AMAZON.COM,Expense,-42.99" with columns for Date, Description, Category, and Amount.
QBO (QuickBooks Online Format)
A proprietary file format designed for direct import into QuickBooks Online. Based on OFX but optimized for QuickBooks. Includes transaction dates, amounts, payee names, and check numbers.
Example: Converting a Chase PDF statement to QBO format lets you import all transactions directly into QuickBooks Online without manual column mapping.
IIF (Intuit Interchange Format)
A tab-delimited file format used specifically by QuickBooks Desktop (not QuickBooks Online). Supports transactions, lists, and budgets. Being phased out in favor of QBO for cloud-based workflows.
Example: A bookkeeper using QuickBooks Desktop 2024 needs IIF files. Each line contains tab-separated fields: TRNS, DATE, ACCNT, NAME, AMOUNT.
OFX (Open Financial Exchange)
An XML-based standard for exchanging financial data between institutions and applications. Supported by most accounting software. More structured than CSV but less widely editable.
Example: Your bank offers OFX downloads directly. If not, converting a PDF statement to OFX format enables import into Microsoft Money, Quicken, or GnuCash.
XLSX (Excel Workbook)
The default Microsoft Excel file format. Supports multiple sheets, formulas, formatting, and large datasets. Often the first step in converting bank statements for analysis before importing to accounting software.
Example: Converting a 40-page annual bank statement PDF to XLSX creates a sortable, filterable spreadsheet with date, description, debit, credit, and balance columns.
MT940 (SWIFT Statement Format)
An international electronic bank statement format defined by the SWIFT network. Used primarily in European and international banking. Contains structured transaction data with standardized tags.
Example: European banks often provide MT940 files for corporate accounts. Tag :60F: marks the opening balance, :61: marks individual transactions, and :62F: marks the closing balance.
PDF Bank Statement
A bank statement in Portable Document Format, either digitally generated by the bank or scanned from a paper statement. The source format for most bank statement conversion workflows.
Example: A client sends you a 12-page Chase bank statement PDF. You upload it to Zera Books, which extracts all transactions and exports them to CSV, QBO, or Excel.
Fees, Charges & Banking Terms
Overdraft
When a transaction exceeds the available balance, the bank may cover it (overdraft protection) or reject it. Overdraft fees range from $25–$35 per occurrence. Shows on statements as a negative balance or separate fee line.
Example: Your account has $100 and a $150 debit posts. With overdraft protection, the bank covers it and charges a $34 overdraft fee. Your balance becomes -$84.
Hold / Pending Transaction
A temporary freeze on funds for an authorized but not yet settled transaction. Common with hotel and gas station charges. The hold amount may differ from the final charge.
Example: A gas station places a $100 hold when you start pumping, but the final charge is $45.67. The $100 hold releases after 1–3 business days.
Interest Earned
Money the bank pays you for keeping funds in an interest-bearing account. Appears as a credit, typically monthly. The rate and amount depend on account type and balance.
Example: "INTEREST PAYMENT" with a $3.42 credit on a savings account earning 0.50% APY on an average balance of $8,200.
Foreign Transaction Fee
A surcharge applied to purchases made in a foreign currency or processed through a foreign bank. Typically 1–3% of the transaction amount. Appears as a separate line item on the statement.
Example: A $100 USD equivalent purchase in London incurs a 2.5% foreign transaction fee: the purchase posts as $100 and the fee posts as a separate $2.50 debit.
Returned Item Fee
A fee charged when a deposited check or payment bounces because the payer had insufficient funds. Different from NSF: NSF is when your check bounces, returned item is when someone else's check bounces after you deposit it.
Example: A client's $1,500 check bounces after you deposit it. The bank reverses the $1,500 deposit and charges a $15 returned item fee.
Stop Payment
An instruction to the bank to not process a specific check or payment. Banks charge $25–$35 for stop payment orders. The order typically expires after 6 months.
Example: You realize check #1055 was sent to the wrong vendor. You call the bank to place a stop payment before it clears, preventing the $2,000 from leaving your account.
Multi-Account & Business Banking
Multi-Account Statement
A single PDF containing statements for multiple accounts (checking, savings, credit card, line of credit) under one account holder. Common with business banking relationships where a single login manages several accounts.
Example: A 20-page PDF from TD Bank contains statements for a business checking, a business savings, and a business Visa account. Each section has separate account numbers and balances.
Consolidated Statement
A summary statement that combines activity from multiple accounts into one overview document. Shows balances and totals for each account but may not include individual transaction detail.
Example: A Bank of America consolidated statement shows total assets of $87,000 across checking ($25,000), savings ($50,000), and a CD ($12,000) with high-level summaries.
Sub-Account
An account that falls under a parent or master account. Used by businesses to track separate departments, projects, or entities while maintaining one banking relationship.
Example: A construction company has a master account with sub-accounts for each project site, making it easier to track expenses per project.
Sweep Account
An account arrangement that automatically moves excess funds between a checking account and an interest-earning investment account at the end of each business day.
Example: Your business checking maintains a $10,000 target balance. Any excess is swept to a money market account overnight and swept back if the checking balance drops below $10,000.
