Examples
Closed sale of a foil stamper
You run a bookbinding studio. On April 9 you sell a used foil stamper to another bindery for $2,100 cash; the fixed-asset schedule shows cost $6,400 and accumulated depreciation $3,520, so leftover book is $2,880. Title and the machine have both moved, so gain or loss is the net after the usual rules: $2,100 minus $2,880 is a $780 loss. In QuickBooks Online or Xero, take the stamper off the fixed assets list (clear $6,400 cost and $3,520 accum dep), record the $2,100 deposit, and post $780 to Other expense (loss on sale). Do not book $2,100 as bindery income, and do not compute the result from the $6,400 invoice; neighbor gain is only the benefit side, and this closed deal is a loss.
A listed phoropter is not closed
You run an optometry practice. On November 6 you list a used phoropter with a clinic-equipment marketplace at $1,450; leftover book is $980. A buyer says they will take it in December if their remodel finishes, but no money has moved and the phoropter is still in your exam room. Do not post a $470 gain or loss: the definition requires a concluded transaction. Leave the asset on the fixed-asset schedule until they pick it up and pay, then compute the net; a listing price is not a result.
Why it matters
Gain or loss is the net leftover after you apply the usual bookkeeping rules, or the tax rules, to a closed deal, a closed group of deals, or a closed accounting period. You compute it when a sale or disposal is actually finished, or when you close a month or year; you will not post this most weeks. Neighbor gain is only the benefit side. Treat an unfinished offer as already booked, dump sale proceeds into ordinary sales, or skip leftover book, and profit is wrong; tax rules may use a different basis than the books, so do not invent a tax rate.
