Perimeter Use cases Marketing

Return measured on your sales, not the dashboard’s

Every platform reports well on itself. Perimeter matches spend against the sales that actually happened in your ERP or e-commerce, and tells new customers apart from those who already bought from you.

The retargeting campaign brings in fewer new customers, but the ones it brings repurchase at twice the rate.

Spend stops being decided by the platform’s number

Today

  • Each platform reports its own conversions and the totals don’t add up.
  • CAC is calculated with the sales the dashboard reports, not invoiced sales.
  • There’s no telling new customers apart from existing ones.
  • The weekly report is built by hand every Friday.

With Perimeter

  • One sales number: the one in your systems, for every platform.
  • CAC is calculated against actual sales, with your team’s definition.
  • Repurchase is measured at 30, 60 and 90 days from the first purchase.
  • The report generates and sends itself, already written.

What Perimeter does for marketing

Attribution

Spend next to the sales that actually happened

Perimeter joins each platform’s spend with the orders in your ERP or e-commerce, applying your attribution window and your definition of a new customer.

  • Matches spend against invoiced sales, not reported sales
  • Applies the attribution window your team defined
  • Shows the SQL behind every return figure

Cohorts

Returning customers, actually measured

Every campaign is tracked beyond the first purchase. Perimeter builds the cohort and tells you what the customer each peso brought in is really worth.

  • Repurchase measured at 30, 60 and 90 days
  • Cumulative value by acquisition cohort
  • Separates new customers from those already in your base

Reports

The Friday report writes itself

Define once what you want to see. Perimeter builds the report with live data, writes up what changed and why, and drops it in the team’s channel.

  • Runs on your schedule, without anyone triggering it
  • Summarizes what changed, by how much and what it means if it continues
  • Pauses for review if a figure falls out of range

The real questions

What marketing asks on any given Tuesday

Each one is answered in the conversation, with its chart and the SQL behind it. When the number matters, anyone can audit where it came from.

Which campaign brought in customers who came back to buy again?
Compare CAC by channel using ERP sales, not the platform’s.
Where are we spending on audiences that already buy from us?
What is a customer acquired in each channel worth at 90 days?
Which campaigns increased spend without moving invoiced sales?
Build the weekly spend report and send it on Fridays.

How the weekly report comes together

The same report that takes half a morning of copy-and-paste today, running on its own.

STEP 01

Reads each platform

Pulls search, social and display spend as each platform reports it.

STEP 02

Matches it to your sales

Joins spend with actual orders using your attribution window.

STEP 03

Checks coverage

If a platform hasn’t reported yet, it says so instead of publishing a partial total.

STEP 04

Lands in the channel

The team gets the summary with the chart, the variance and the SQL one click away.
