Start with the equipment amount
Record the offer date, equipment scope and amount exactly as quoted. Ask whether the figure is before or after any deductions. Keep a separate column for seller-paid fees, preparation, loading and transport. Identify costs already included in the buyer’s price so you do not subtract them again.
Use a labeled example
Hypothetically, an equipment offer of $24,000 less a $1,000 seller fee and $2,500 of seller-arranged removal leaves $20,500 before other applicable costs. If the $24,000 was already quoted after the fee, subtracting that fee again would understate the result. These numbers illustrate arithmetic, not generator values or SellMyGen pricing.
Keep uncertain costs out of a false final total
Mark unquoted work as pending rather than zero. If you use an estimate, show its source and date. Present a subtotal of known amounts plus a list of unresolved expenses. Do not describe the result as guaranteed proceeds while inspection adjustments or removal work remain unsettled.
Reconcile the accepted terms
Before relying on the worksheet, compare every line with the written offer and service scopes. Confirm who pays each charge and when the amount can change. Keep the worksheet as a decision aid beside the transaction documents; it is not a tax calculation or evidence that money has been received.
