Financial Accounting and Bookkeeping

01Purpose and scope

• This manual supports the course Financial Accounting and Bookkeeping. It describes how the work is actually done by people who record transactions, maintain the general ledger, reconcile accounts, and prepare the statements that owners, lenders, managers, and tax preparers rely on. The focus is on small and mid-sized organizations, although the same core method applies to larger entities with more staff, more entities, and more systems.
• Bookkeeping is the routine capture and classification of transactions. Financial accounting is the wider process that turns those records into statements under a recognized framework, usually U.S. generally accepted accounting principles or International Financial Reporting Standards depending on where the entity reports. This manual covers both, but it treats bookkeeping as the foundation because statement quality depends on the quality of the underlying entries.
• The guidance here does not replace qualified professional judgment, approved internal procedures, or required authorization. Tax treatment, payroll withholding, sales tax, and filing obligations vary by jurisdiction and change over time, so confirm current rules with the relevant tax authority or a licensed professional before relying on any treatment described here.

02Core principles

• Double-entry bookkeeping is the central idea. Every transaction affects at least two accounts, and the total of debits always equals the total of credits. The accounting equation, assets equal liabilities plus equity, is the check that tells you whether the structure holds together. If a trial balance does not balance, the error is somewhere in the posting process, not in the balance sheet itself.
• Accrual and cash bases produce different timing. Under accrual accounting, revenue is recorded when earned and expenses when incurred, regardless of when cash moves. Under the cash basis, entries follow receipts and payments. Many small businesses use cash records for tax purposes, but lenders and investors often expect accrual statements, so know which basis each user needs before you set up the books.
• Several other principles guide daily decisions. Matching links expenses to the revenue they helped produce. Consistency means you apply the same method from one period to the next unless there is a documented reason to change. Materiality lets you decide how precisely an item must be handled based on whether it would influence a reasonable user. Going concern assumes the entity will continue operating unless evidence says otherwise. Separate entity keeps the owner personal transactions out of the business records.
• Every entry needs evidence. A source document such as an invoice, receipt, bank statement, contract, or payroll register should support each transaction, and the reference to that document should be retrievable later. Without that link, the ledger shows what someone said happened rather than what did happen, and an auditor, tax reviewer, or new bookkeeper cannot follow the trail.

03Planning and preparation

• Start with the chart of accounts. Group accounts into assets, liabilities, equity, revenue, cost of sales, and operating expenses, then add detail that matches how management reads results. A restaurant may need separate accounts for food, beverage, and labor, while a consulting firm may track subcontractor costs and reimbursable expenses. Avoid creating accounts for every one-time item, because a bloated chart makes reports harder to read and reconcile.
• Set opening balances carefully. Take a trial balance or statement from the prior records as of a defined cutoff, confirm bank and loan balances against third-party statements, and agree receivables and payables to aging reports. If you convert from another system, keep the old files and a conversion journal so you can explain any difference later.
• Decide the reporting calendar and the close schedule before the first busy period arrives. Define when transactions must be entered, when bank feeds are reviewed, when payroll journals post, and when management receives the statements. Assign a due date to each step and name a backup for each person, because most close delays come from one missing document or one unavailable approver.
• Choose tools that match the size of the work. A spreadsheet can serve a sole proprietor with few transactions, but it offers weak audit trails and limited access control. Accounting software with user roles, locked periods, attachment storage, and an activity log is more appropriate once several people post entries or when lenders request reviewed statements. Whatever tool you use, document the settings that affect results, such as default accounts for bank feed rules, sales tax setup, and depreciation methods.

04Recommended workflow

1. 1
   : Collect source documents as they arrive rather than at period end. Scan or file vendor invoices, customer invoices, receipts, bank and card statements, payroll registers, and loan notices into a shared folder or the accounting system. Record the file name or document number next to each transaction so the link is easy to follow.
2. 2
   : Record each transaction in the appropriate subledger or journal. Enter sales invoices in accounts receivable, bills in accounts payable, and payments against those documents. Use the transaction date from the source document, not the date you entered it, and classify the amount to the account that matches its nature. When you are unsure, post to a clearly labeled suspense account and note the question for review rather than guessing.
3. 3
   : Post to the general ledger and confirm that subledger totals agree with their control accounts. Run the posting reports and check that no batch failed silently. If the system posts automatically from subledgers, confirm the mapping has not changed since the last close.
4. 4
   : Reconcile bank, card, and loan accounts to the third-party statement. Start with the statement ending balance, match each cleared item to a ledger entry, and list outstanding checks and deposits in transit. Investigate every difference, because a small unexplained item often hides a duplicate bank feed entry, a missed fee, or an unauthorized charge.
5. 5
   : Reconcile subledgers to control accounts for receivables, payables, inventory, payroll liabilities, prepaid expenses, and fixed assets. For receivables, review aged balances and confirm that large or old items are still collectible. For inventory, compare the count or perpetual record with the general ledger and document the cause of any shrinkage.
6. 6
   : Prepare adjusting entries. These include accrued wages and interest that have not yet been paid, prepaid insurance and rent being released to expense, depreciation on property and equipment, an estimate for doubtful receivables, and corrections for inventory counts. Each entry should have a memo explaining the basis for the estimate and the source used to calculate it.
7. 7
   : Prepare the trial balance and review it for unusual balances. Look for accounts with debit balances where credits are expected, revenue that moved sharply without a known cause, and expense accounts that are empty when they should not be. Then produce the income statement, balance sheet, and cash flow statement, and add notes describing the accounting policies and any significant estimates.
8. 8
   : Close the period and lock it. Record the close date, store the signed reconciliations and the adjusting entry log with the statements, and restrict posting to the closed period except through a documented reversing or correcting entry approved by someone other than the preparer. Archive the working files so the package can be reproduced later.

05Quality checks, risk controls and compliance

• Segregation of duties is the most important control in a small office. The person who records payments should not also approve vendors, sign checks, or reconcile the bank account. If staffing does not allow full separation, compensate with independent review, such as an owner who reviews the bank reconciliation and the list of vendor changes each period.
• Use approval thresholds and review of manual journal entries. Manual entries that move money between accounts, change prior periods, or affect equity should be reviewed by a second person and supported with documents. Set a dollar threshold above which any entry needs sign-off, and keep a log that shows who prepared and who approved each one.
• Protect access and data. Give each user the least access needed for their role, enable multifactor authentication where the software supports it, back up records on a schedule, and test the restore process. Personal information in payroll and vendor files is subject to privacy and data security laws that vary by location, so confirm the requirements that apply to your entity.
• Check sales tax, payroll taxes, and information reporting against the rules that apply where the entity operates. Deposit schedules, rates, exemptions, and retention periods differ by jurisdiction and change over time. Refer to the relevant tax authority or a licensed tax professional for current requirements, and keep the reconciliations that show the amounts reported agree with the amounts recorded.
• Watch for fraud indicators. Common signs include round-number payments, new vendors with no tax identification, duplicate invoices with slightly different amounts, payments to employee personal accounts, and frequent voided checks. Investigate these patterns promptly, and escalate suspected misconduct according to the organization's written policy and, where required, to qualified advisers or authorities.
• Apply materiality and cutoff testing. Confirm that goods and services received before the period end are recorded as liabilities even if the invoice arrives later, and that revenue for work completed after the period end is deferred. Small items may be expensed without detailed analysis, but significant balances and estimates need documented support.

06Collaboration and documentation

• Bookkeepers work with owners, managers, payroll providers, tax preparers, lenders, and external accountants. Each group needs different information. Owners want cash position and profitability, lenders want consistent statements and covenant calculations, and tax preparers need clean classification of deductible and nondeductible items. Agree on the reports each group receives and the date they receive them, so the package does not change without notice.
• Keep a written accounting policies document. It should state the basis of accounting, capitalization thresholds for equipment, depreciation methods and useful lives, inventory costing method, revenue recognition approach for the main services or products sold, and how estimates such as bad debts are calculated. When the policy changes, record the reason and the effect on prior statements.
• Maintain a journal entry log and a reconciliation file. Each entry, reconciliation, and adjustment should show the preparer, the reviewer, the date the work was done, and the supporting document. Auditors and external preparers often start with these records, so a clear log can shorten an engagement considerably.
• Write down open questions and their resolution. When a transaction is classified in an unusual way, note the reason and the person who agreed to it. Shared folders should use consistent names so the next person can find the bank statement, the loan agreement, or the payroll register without asking.

07Measures and continuous improvement

• Measure the process as well as the results. Useful indicators include the number of calendar days from period end to final statements, the number of adjusting entries posted after the statements were first issued, the count and age of unreconciled items, the share of transactions with an attached document, the number of manual journal entries, and the number of errors found in review. Set targets that suit the organization, because a suitable target for a single-owner shop will differ from one for a multi-site company.
• Track the business indicators the statements support. Accounts receivable aging shows how quickly customers pay, accounts payable aging shows whether bills are being paid on terms, and the cash forecast shows whether the entity can meet obligations. Trends in gross margin by product line often reveal pricing or cost problems earlier than the bottom line does.
• Review the close after each cycle. Ask which steps took longer than planned, which entries were corrected later, and which documents arrived late. Change one thing at a time, such as moving the bank reconciliation earlier or adding a checklist line for a recurring accrual, then check whether the next close improved.
• Be realistic about limits. Historical trends help, but they do not predict unusual events such as a lawsuit, a large customer loss, or a change in tax law. When estimates depend on judgment, record the assumptions and revisit them as new evidence arrives.

08Common mistakes and how to prevent them

• Mixing personal and business transactions is common in owner-managed entities. Prevent it by opening separate bank and card accounts, paying owner draws through a defined process, and reviewing any transaction that does not match the business purpose. Personal expenses paid with business funds should be recorded as distributions or receivables from the owner, not as operating expenses.
• Recording by payment date instead of obligation date understates liabilities and overstates profit in busy periods. Record bills when received and approved, and record revenue when the service or goods are delivered, unless the entity uses the cash basis for a documented reason.
• Failing to reconcile the bank account is the most frequent cause of unexplained differences. Reconcile every bank and card account to its statement on a regular schedule, and resolve each item before the next period begins. Leaving items in suspense or uncleared accounts hides problems until they are larger.
• Duplicate entries from bank feeds and imported files inflate expenses and revenue. Set matching rules carefully, review new rules before they run, and check for identical amounts and dates before posting. Keep a record of rules and changes so the source of an error can be traced.
• Capitalizing or expensing items without a policy leads to inconsistent results. Set a capitalization threshold, record the reasoning for significant purchases, and review fixed asset additions at each close. Items that extend useful life or add capacity often belong on the balance sheet, while routine repairs usually belong in expense.
• Relying on software defaults without review is another source of error. Default accounts, tax codes, and depreciation settings may not match your policies. Check each default when you set up the system and after any software update.
• Reviewing only the totals hides classification errors. A balanced trial balance can still contain expenses in the wrong accounts or revenue in the wrong period. Sample transactions from each account and compare them with source documents at least once in each cycle.

09Practical checklist

• Confirm the trial balance balances and that the opening balances agree with the prior period close.
• Attach a source document to every transaction that is entered or imported during the period.
• Reconcile every bank, card, and loan account to its third-party statement and clear all differences or document them.
• Reconcile receivables, payables, inventory, payroll liabilities, prepaid expenses, and fixed assets to their control accounts.
• Post accrued expenses, deferred revenue, depreciation, and bad debt estimates with a memo and support for each.
• Obtain a second person review for manual journal entries and any change to a prior period.
• Review the income statement and balance sheet for unusual movements and document explanations for the largest changes.
• Lock the closed period, archive the signed reconciliations and entry log, and confirm the backup has been tested recently.
