Now live

Caeros is live on the Shopify App Store

By Drew Washington, founder of Caeros. September 2026.

Why I built this for Shopify specifically

Before Caeros: $1.7M a year in ad spend, seven channels, one hand-built Google Sheet. It worked — until the week I was out and no one else could read it. Most Shopify merchants running multi-channel ad spend are in that exact position: one person, one spreadsheet, no audit trail, nothing that reconciles itself. Caeros fixes that — now right inside Shopify admin, where the budget owner already spends their day.

What's in the Shopify app

• →Daily and weekly budget targets per channel, adjusted automatically for holidays and days remaining in the month.
• →Month-end reconciliation — compare actual spend to budget, stop channels that should free up budget, reallocate the surplus.
• →Forecast how a budget change affects revenue, by channel, region, or product — nothing saves until you confirm it.
• →An append-only ledger — every budget decision is a permanent record, never a silent edit.

Caeros tracks budget and spend only — no clicks, no ROAS, no campaign or bid access. It reads spend dollars and nothing else. That's a permanent scope boundary, not a missing feature: less access is less risk for the person who has to approve it.

$9.99/month flat. Never a percentage of spend.

Same honesty about pricing as the standalone app — one flat price no matter how large your budgets get, so there's never an incentive on our side to grow your spend.
