Calculate line totals with multiplication
Multiply quantity by unit price to get a line total.
Accounting Excel is reconciliation work: two lists that should agree, and the job of finding out where they do not.
The month-end close is a sequence of comparisons — ledger against bank, subledger against control account, this period against last. Most of it is lookups and conditional sums over data that arrives inconsistently formatted, with trailing spaces and numbers stored as text.
Values that look identical but will not match, because one side has a trailing space or a number stored as text. A lookup returns #N/A and the instinct is to blame the formula rather than the data.
Aging receivables by invoice date, summing by account code with more than one condition, and spotting why two apparently identical values fail to match.
Each of these is a task the job asks for, with the exercises that drill it.
The arithmetic under everything else: extending a quantity by a price, working a margin, and building a date Excel will actually treat as a date.
Reference: DATE
How old is this receivable, and which ones are past terms. The part of the close that gets asked about in every interview.
Totals that answer a question rather than adding up a column — one condition, then several, and the argument order that trips everyone.
Pulling a price, a band or a term out of a reference table — including the two-hop lookup where what you have is not in the table you need.
The same invoice entered twice looks like two invoices until something counts them.
Reference: COUNTIF
Ledger against bank, subledger against control. Not which totals differ, but which specific rows are missing from one side.
Reference: COUNTIF
A trailing space, or a number stored as text. The lookup returns #N/A and the formula is not the problem.
A cumulative column that still works when the data grows, which is the difference between a report you rebuild and one that rebuilds itself.
Reference: SUM
