Record only four basic fields
A daily spending log remains useful when it takes little effort to maintain. Start with the date, amount, currency and a simple category. If you paid for somebody else, add a short note without turning every purchase into a long story. The aim is to see the remaining allowance and the direction of spending. You do not have to judge every purchase as it happens. A brief evening update can provide a clearer picture than constant checking throughout the day, provided you keep the details you will need in a form you can retrieve later.
Separate the event from settlement
The amount at purchase and the charge appearing later in an account can be different pieces of information. If you use several currencies, preserve the original amount and put any converted value in a separate field. Do not label an estimated conversion as a final charge. Similarly, mark prepaid items so they are not counted again as new spending at the destination. Paying the whole restaurant bill is also different from paying your own share. These distinctions let the log describe your personal trip cost while still showing shared amounts that have not yet been settled between companions.
Review the day in five minutes
On an imagined city break, an evening review could have three steps: add missing entries, total the categories and check the allowance for the remaining days. If a day cost more than expected, first identify the cause. A one-off admission fee calls for a different response from a long transfer repeated every day. Only then decide whether tomorrow's plan needs an adjustment. Avoid turning the log into a list of regrets. Its value is in clarifying the decisions still ahead of you. After returning home, save category totals and a few observations. Those will be easier to use for the next trip than an unsorted collection of receipts with no explanation.
