Buy a piece of equipment, post it to an expense account, and move on. It feels finished. Then the balance sheet is wrong, the depreciation schedule never gets set up, and a year later someone is rebuilding the whole thing during a tax filing.
The Fusion CPA blog has a full step-by-step walkthrough of doing it properly in QuickBooks Online. Here is the shape of it.
A fixed asset goes in at its full capitalized cost, not the invoice subtotal. That means the purchase price plus tax, shipping, and installation. Everything it took to get the asset ready for its intended use.
Say you buy a press for $18,500 and pay another $650 to have it delivered and installed. You record $19,150, not $18,500. That difference follows the asset for its entire life, through every depreciation entry and into the gain or loss when you eventually sell it.
Automatic depreciation calculation is only on QuickBooks Online Advanced. On Simple Start, Essentials and Plus you are making a periodic manual journal entry: debit Depreciation Expense, credit Accumulated Depreciation.
That is not a reason to change plans. It is a reason to know which one you are on before you assume the software is handling it, because nothing warns you at year end that it is not.
The failure is rarely dramatic. It shows up as:
Selling the asset is its own sequence, and QuickBooks Online has no "mark as sold" checkbox the way QuickBooks Desktop does. You remove the original cost and the accumulated depreciation, then post the proceeds and recognise the gain or loss.
State treatment varies. Some states conform to the federal rules on bonus depreciation and Section 179, others decouple from them entirely, which means a different schedule for the same asset. That matters most if you operate in more than one state.
The full walkthrough has the worked example, the journal entries, the fixed-versus-working asset comparison, and a breakdown of when this is worth keeping in-house versus handing to an outsourced controller.
