How do I record ad spend manually?

Open Ad Spend in the Attribution menu and log how much you spent per day, source, and campaign — Decisa pairs each entry with the matching rows in your ROAS report, so ROAS works even before you connect an ad platform.

Before you start

• A workspace with the Attribution module active.
• ROAS needs both sides of the math: revenue comes from your tracked orders, Spend comes from these entries (or, later, from a connected ad platform). No spend recorded means no ROAS.
• Know the exact utm_source and utm_campaign values your ads use — the pairing depends on them.

Steps

1. Open Ad Spend

   Use Sidebar → Attribution → Ad Spend. The page is titled Ad spend, and the form card is called Add an entry.

2. Fill in Day and Amount

   Pick the Day the money was spent and enter the Amount (for example, 125.50). Choose the currency next to the amount — it defaults to USD, so switch it if your ad account bills in another currency.

3. Pair it with Source and Campaign

   Fill Source, Medium (optional), and Campaign with the same values your UTM links use — for example, source google and campaign summer_launch. These values are how the entry finds its row in the ROAS report.

4. Save spend

   Click Save spend. You'll see an Ad spend saved confirmation, and the amount field clears so you can log the next day or campaign without retyping everything.

What happens next

• Your entries feed the Spend column of the ROAS report (Sidebar → Attribution → Overview), and ROAS is calculated as tracked revenue divided by that spend.
• The page explains this under How this is used: when ad-platform connections arrive, automatic syncs will take over — but your manual entries are preserved as the source for past dates.
