Prices move. Expenses drift. Both hide in the details.

A cheaper listing can change its terms. A familiar invoice can rise, repeat, or cross a threshold. Catching either means comparing the evidence, not just the total.

One change brief for the costs worth a look.

Your assistant records the current amount, prior baseline, terms or invoice evidence, timestamp, and source. You decide whether to book, question a charge, or do nothing.

Two prices moved — the JFK–LIS fare dropped $122 on the same fare terms — and three expenses need a look, including a possible duplicate courier invoice.
