# Review and queries

> Approve days oldest first, ask about a line with a query, or send a day back for changes.

Owners and supervisors review each station's submitted days under **Review**. The sidebar shows how many are waiting, and you get the summary by email when a day is submitted.

## Oldest first

Days are approved in order at each station: the oldest submitted day is approved before the next. A day waiting for review never stops the station from trading the next day.

## Approve

Open the day, check the meters and their photos, the money and the explanations, then **Approve**. An approved day is final.

The quickest way through the photos is the **Photos** section: tap the first one, then **Next**. Each photo shows the figure typed for it. See [Meters and photos](/daily-sheet/meters-and-photos#checking-photos-reviewers).

## Ask about a line

Use **Raise a query** to ask about one line: a meter, the cash, a tank. The manager answers in Gasos, so the question and answer stay with the day. Resolve each query before approving.

## Send it back

**Request changes** returns the day to the manager with your note. They correct it and resubmit; the sheet keeps each revision and the history of who did what.

## Your own day

If you submitted a day yourself, someone else reviews it. When nobody else in the company can review, you can approve it, and Gasos labels it **self-approved**.
