Control Accounts vs Regular Accounts

Not every account needs detailed backup. The ones that do are called control accounts.

TypeHas Subsidiary Ledger?Why?
Control accountYesNeed to track individual items (customers, jobs, vendors)
Regular accountNoOne balance is sufficient

Examples:

Control AccountIts Subsidiary Ledger Contains
Accounts ReceivableIndividual customer balances
Accounts PayableIndividual vendor balances
Work in ProcessIndividual job cost sheets
Finished GoodsIndividual completed job records
Manufacturing OverheadIndividual overhead cost records by type
Regular AccountWhy No Subsidiary
CashOne balance tells you what you have
Rent ExpenseDon’t need breakdown by… what?
Sales Revenue(Though some companies do track by product line)

The Reconciliation Rule

Control account balance = Sum of subsidiary ledger balances

If they don’t match, something was recorded incorrectly.


Example: WIP as a Control Account

General Ledger                     Subsidiary Ledger (Job Cost Sheets)
─────────────────                  ─────────────────────────────────────
Work in Process                    Job 101:    $15,000
    $47,000 (control)       =      Job 102:    $22,000
                                   Job 103:    $10,000
                                               ────────
                                   Total:      $47,000 ✓

When you debit WIP $6,000 for direct materials on Job 101:

  • The general ledger WIP account increases by $6,000
  • Job 101’s cost sheet (subsidiary) increases by $6,000

Both update simultaneously. The job cost sheet is the subsidiary record.


Clearing Accounts

A clearing account is a different concept—it’s an account where debits and credits should net to zero over time.

TermMeaning
Control accountHas subsidiary detail that must reconcile
Clearing accountReceives offsetting debits and credits

MOH is both:

  • Control account → backed by detailed records of each overhead cost type
  • Clearing account → actual costs flow in (debit), applied costs flow out (credit)
Manufacturing Overhead (Clearing Account)
┌─────────────────────┬─────────────────────┐
│       Debits        │       Credits       │
│   (Actual costs)    │  (Applied to WIP)   │
├─────────────────────┼─────────────────────┤
│ Indirect materials  │ Applied overhead    │
│ Indirect labour     │ (via POHR × actual  │
│ Factory utilities   │  activity)          │
│ Factory depreciation│                     │
│ Factory insurance   │                     │
├─────────────────────┼─────────────────────┤
│      $50,000        │      $48,000        │
└─────────────────────┴─────────────────────┘
         Balance: $2,000 debit (underapplied)

Ideally debits = credits and MOH clears to zero. When it doesn’t → underapplied or overapplied overhead. See LO7.

The Two Distinct Processes

The textbook emphasizes that recording actual overhead and applying overhead are “two separate and entirely distinct processes”:

ProcessWhen It HappensEntryWhat It’s Based On
Recording actualThroughout the period as costs incurDr. MOH / Cr. VariousReal dollars spent
Applying to jobsWhen jobs use activityDr. WIP / Cr. MOHPOHR × actual activity

Why this matters: These processes happen independently. You don’t wait to see how much actual overhead you incurred before charging jobs. You apply overhead using the predetermined rate as work happens. The two amounts (actual collected vs applied released) won’t automatically match—that’s why MOH can have a year-end balance.

See Applied vs Actual for the full explanation of why overhead uses applied (estimated) costs while direct materials and direct labour use actual costs.


Account Classifications

Accounts can be categorized multiple ways simultaneously:

By Financial Statement

TypeExamplesWhere It Appears
AssetCash, AR, Inventory, WIP, EquipmentBalance Sheet
LiabilityAP, Wages Payable, Notes PayableBalance Sheet
EquityCommon Stock, Retained EarningsBalance Sheet
RevenueSales Revenue, Service RevenueIncome Statement
ExpenseCOGS, Rent Expense, Wages ExpenseIncome Statement

By Permanence

TypeYear-End TreatmentExamples
Permanent (Real)Balance carries forwardAssets, Liabilities, Equity
Temporary (Nominal)Closes to Retained EarningsRevenues, Expenses

By Detail Level

TypeHas Subsidiary?Examples
Control accountYesAR, AP, WIP, Finished Goods, MOH
Regular accountNoCash, Rent Expense

By Function (Managerial)

TypePurposeExample
Clearing accountCollects costs then releases themManufacturing Overhead
Accumulation accountBuilds up costs on a cost objectWork in Process

Why This Matters for Job-Order Costing

AccountRoleControl?Clearing?
Raw MaterialsHolds materials before productionYes (by material type)No
Work in ProcessAccumulates costs on jobsYes (job cost sheets)No
Finished GoodsHolds completed job costsYes (by job)No
Manufacturing OverheadCollects indirect costs, releases via POHRYes (by cost type)Yes
Cost of Goods SoldReceives cost when jobs sellNoNo

MOH is unique—it’s the only one that’s both a control AND a clearing account.
