Channel mix
Meta CPA looks great. Repeat rate looks terrible.
Pull 60-day cohort retention by source. If Meta cohorts repeat at half the Google rate, the budget conversation changes from creative to source quality.
Advertising & ROI
The ad channel that wins on day one isn't always the one that pays you back.
By the Numbers stitches Meta, Google, and TikTok ad spend to Shopify revenue, LTV, and cohort retention - in a single report. The CFO question (‘is this channel actually working?’) finally has a real answer.

One dashboard for the question your CFO keeps asking.
GA4 says one number. Meta says another. Shopify says a third. By the Numbers reconciles them - using your own order data as the source of truth - so you can stop apologizing on the weekly ops call.
- Spend, revenue, ROAS, and CPA pulled directly from Meta, Google, and TikTok
- Reconciled against Shopify orders - not third-party pixel guesses
- Slice by campaign, ad set, and creative
- Stack against blended new-vs-returning revenue for a real picture

Replace ROAS with the metric that pays the bills.
Day-one ROAS makes the cheapest CPA look like a winner. By the Numbers ties spend to 30-, 60-, and 90-day customer value, so the channels that buy you loyal customers (not just one-and-dones) finally get credit.
- 30/60/90-day LTV per acquisition channel
- Cohort repeat rate, side-by-side, by source
- Net contribution margin per acquired customer (with COGS input)

Three Meta ad sets all run at break-even ROAS.
Look at downstream LTV by ad set. The break-even one with a 1.4× repeat rate is the winner. Kill the one with 1.0×.
Scale up
TikTok looks promising but you can't justify the spend.
Filter the 30-day cohort attributed to TikTok. If AOV-on-second-order beats Meta's, you have a defensible case to triple it next week.
