A controller treats depreciation and amortization as part of the monthly close process rather than a year-end afterthought. The work involves maintaining detailed schedules, booking adjusting entries, and making sure fixed assets and intangibles are accurately reflected on the balance sheet and income statement.

The first task is maintaining depreciation schedules. Every significant asset the business owns needs to be tracked with its original cost, acquisition date, useful life, and depreciation method. A controller keeps these schedules current by adding new purchases, removing disposals, and calculating the monthly expense for each asset. This isn’t something most bookkeepers handle because it requires judgment about capitalization thresholds and useful life assumptions.

Monthly adjusting entries move depreciation and amortization expense onto the income statement while reducing the book value of assets on the balance sheet. Without these entries, your financial statements overstate asset values and understate expenses. A controller books these entries as part of the standard month-end close so your financials are accurate when you review them.

The method and useful life matter more than most business owners realize. Straight-line depreciation spreads the cost evenly over an asset’s life. Accelerated methods front-load the expense for tax purposes. A controller evaluates which approach makes sense for each asset class and ensures consistency with IRS guidelines and your tax strategy. Using the wrong method or an unrealistic useful life creates problems when tax returns get prepared.

Amortization works similarly for intangible assets like purchased software, patents, or goodwill from acquisitions. These get spread over their useful life or the period the business will benefit from them. Controller services include reviewing these schedules to make sure nothing is being amortized incorrectly or missed entirely.

Beyond the monthly entries, a controller reviews whether assets are still in use and worth their book value. Equipment that’s been scrapped or sold needs to be removed from the schedule with any gain or loss recorded properly. Assets that have lost value faster than expected may need impairment adjustments. This kind of oversight prevents your balance sheet from carrying ghost assets that no longer exist.

The work also ties into capital planning. Knowing when major assets will be fully depreciated helps with equipment replacement decisions and cash flow forecasting. A controller in Boca Raton working with your business will flag when expensive equipment is nearing the end of its useful life so you can plan ahead rather than react to breakdowns.

For businesses with significant fixed assets or intangibles, depreciation and amortization directly impact reported profitability. Getting these entries wrong makes your financial statements unreliable for decision-making and creates cleanup work before tax filing. A controller handles this correctly from the start so the numbers you see each month reflect reality.
