Each spend entry is a record of what one campaign cost on a given date, plus how it performed. You can log entries as often as you like. Many authors log once a day or once a week from their ad platform's report.

## Log a spend entry

1. In the left sidebar, click **Ad Spend Tracker**.
2. Click **Log Spend**.
3. Choose the **Campaign**. Campaigns are listed with their platform, for example "Launch Push (Amazon Ads)".
4. Set the **Date** the spend applies to.
5. Check the **Currency**. It is filled in from the campaign, but you can change it.
6. Enter the **Spend Amount** (required).
7. Fill in any of the optional fields:
   - **Impressions**: how many times the ad was shown.
   - **Clicks**: how many people clicked it. Used for the average cost per click.
   - **Attributed Sales**: how many copies the platform says the ad sold.
   - **Attributed Revenue**: the money those sales brought in. This is what the revenue and ROI figures are based on.
   - **Notes**: anything you want to remember, such as a bid change.
8. Click **Log Spend**.

If you have no campaigns yet, the window says "You need at least one campaign before logging spend." Click **Create Campaign First** to make one.

## See the entries for a campaign

Click a campaign's row in the **Campaigns** list to expand it. The entries are listed newest first with their date, spend, impressions, clicks, sales, revenue and notes. Click the row again to collapse it.

## Fix a mistake

Spend entries can't be edited once saved. To correct one, expand the campaign, click the trash icon on the wrong entry, confirm **Delete**, and then log it again with the right numbers. Deleting an entry is permanent.

## Tips

- Revenue isn't pulled from Sales Tracker. Enter the revenue your ad platform reports (or your own estimate) in **Attributed Revenue**, otherwise the campaign's ROI will show as a loss.
- Log entries in the same currency where you can. The totals only add up entries in your main currency (see the article on how ROI is calculated).
