What is the difference between maintenance and repair work? There seems to be some overlap. Let us define our terms right away:
Indirect Production Departments costs absorption can be complex. Maintenance and Repair departments, in some companies, are critical and costly. In these cases, perhaps a preventive maintenance budget will help establish absorption rates. At the same time, it is not worthwhile to prepare a very complicated absorption system. A simple structure can often give adequate information. After a year or two of use, it may be appropriate to fine tune the absorption system.
Maintenance and Repair activities are tracked within Functional Activity accounts. An ordinary preventive maintenance budget provides special accounts for these activities, (for example, special building maintenance, vehicle maintenance, machine maintenance, etc.).
Internal Accounting helps managers avoid charging an unpredicted repair cost to a single month’s production by supporting preventative repair budgets and estimating operating costs. An annual absorption rate for each Repair department is also recommended. Internal Accounting can treat finished repairs as Assets, and provides the option to re-allocate it to a Department or depreciate it over time. Internal Accounting can treat a large repair as an equipment purchase.
At month end, the Product Inventory accounts (Class 7) transfer its balance to Asset accounts, since these accounts in class 7 are Contra accounts to Assets. Compare these amounts with budgets for true cost insights.
At Month-End, variances are reported by comparing Budgeted activity values with Actual activity values.
Repair departments receive allocated operating costs just as with any other department: costs for salaries, wages, rent, depreciation, phones, office supplies, and work supplies are allocated to Repair Departments (Class 3).
But accurate budgets for repair are not easy, since predicting equipment break down is nearly impossible. A ‘preventative repair budget’ can help by sizing the department personnel, operating costs can be estimated. Historical of different repairs during previous years could be used to project budget amounts.
Repairs that must be tightly controlled should have repair Job-Orders. When a repair is finished, the amount for this repair could be handled in two ways:
Now, we can predict an equipment purchase, but we cannot predict a repair ‘purchase.’ If we estimate a repair budget, and nothing breaks down this month, can we charge future repair costs to today’s production? There are many different solutions to this problem, but the Internal Cost Accounting System recommends the “internal lease” agreement, described in IAE Articles ; Machine Lease Agreement Procedure.
