Examples
Freight and install belong in the band saw's first cost
You run a neighborhood butcher shop. On May 12, an equipment supplier bills $4,385 for a used band saw, a freight company bills $263 to deliver it, and an electrician bills $522 to hardwire and test it so you can cut. Original cost is the primary cost to put that saw in service: $5,170, the invoice plus freight plus install. Enter all three bills in QuickBooks Online or Xero to Equipment so the balance sheet starts at $5,170. Leave freight and install on shipping or repairs and the saw is short $785, and later depreciation runs from the invoice alone.
A later drum rebuild does not change original cost
You run a flooring shop. On March 4, 2024 you put a used belt sander in service from a floor-tool supplier: a $3,910 invoice, $218 freight, and $392 of on-site setup, so original cost is $4,520. On September 21, two seasons later, a repair shop bills $1,340 to rebuild the drum bearings and replace the drive belt, and a helper almost edits the original-cost field on the fixed asset in QuickBooks Online or Xero from $4,520 to $5,860. Leave original cost at $4,520, the first cost to put the sander in service. The rebuild is later work: capitalize it as an improvement if it extends life, or expense it as repairs; do not rewrite the primary cost.
Why it matters
Original cost is the first, or primary, cost of a lasting asset: the invoice plus what it took to get the item working. You set that figure when you acquire a fixed asset and you will not journal a new one most months; it comes back when a later overhaul hits the same asset and you have to decide whether the first-cost number still stands. Leave inbound freight and install off the asset and the starting figure is short, so later depreciation and sale gain or loss run from the wrong base; fold a later rebuild into that same field and you rewrite the first cost instead of recording a separate improvement or a repair. Do not mix this with historical cost, which is the cost to you, the present owner, at acquisition: same family, but that term is about whose invoice you keep, not about gathering the first-cost pieces versus later work.
