Total Cost of Ownership: Attribution Software for SMB Brands

The total cost of ownership of attribution software for an SMB ecommerce brand has six lines, and the licence is usually the smallest: the subscription, the contract length you cannot leave, the pixel or integration someone has to build and maintain, the onboarding weeks before the first usable number, the seats and add-ons, and the cost of the decisions made on a number that was wrong. Causality Engine's lines are EUR 99 once or EUR 299 a month, no contract, no pixel, 1 to 2 minutes to the first read, unlimited seats, and a refund within 30 days, no questions asked. The competitor figures below are only the ones that could be read from a vendor's own page, with the date.

The worksheet

Fill the same six lines for any vendor before comparing the first one.

The sourced competitor figures

As read from vendor pricing pages on 8 September 2026: Northbeam's Starter tier lists at $1,500 a month and Professional at $3,500 a month, with higher tiers quoted (northbeam.io/pricing). Cometly prices on monthly pageviews, quotes on a call and states it has no free trial (cometly.com/pricing); its affiliate page puts a typical Core signup at $750 a month (cometly.com/affiliates, read 2026-09-26). Elevar, a tracking product rather than an attribution model, lists Core at $225 a month with a 15-day trial (getelevar.com/pricing). Triple Whale offers a free tier for smaller stores and prices paid tiers on annual GMV; its pricing page blocks automated reads, so no paid figure is quoted. Rockerbox and Measured do not publish pricing. Setup for the pixel-based tools is a pixel install and platform connections, one to two hours in Triple Whale's case and a managed onboarding for Northbeam, per their public materials. The comparison page carries each record with its source and capture date.

No figure for onboarding hours, seat prices or engineering time is quoted for any competitor here, because none was found on a vendor's own page. Put your own numbers in those lines.

The line that dominates for an SMB

For a brand spending between five and fifty thousand euros a month, the licence is not the largest line. The largest is the last one. A reported ROAS that grades itself, allocated on for two quarters, costs whatever share of the budget went to a channel that was claiming sales it did not cause. The Price of Being Found calls the compounding version of that marketing debt, and the arithmetic that sizes it is the claim ratio: summed platform claims over orders, computed in an hour from data you already hold. The one-hour claim ratio audit is the procedure; marketing debt is the concept.

The second largest line is usually time to first number. A tool that takes six weeks to produce its first read costs six weeks of deciding on the old number, and that cost is invisible on every invoice.

Where the EUR 99 read sits in the worksheet

It is designed to make five of the six lines zero or near it: no contract, no installation, minutes to the first number, no seat fees, and a refund on the sixth line's worst case. The remaining line, the licence, is EUR 99 once, or EUR 299 a month if you want the read to run continuously with automated ingestion, the full look-back and the chatbot. Twelve months of Pro is EUR 3,588 on monthly billing. Whether that is cheap depends on the sixth line, and the read exists to make the sixth line visible.

What to do this week

• If you own the budget: fill the six lines for your current tool, with your developer's hourly rate in line three and last quarter's claim ratio in line six.
• If you have to defend the number: bring the worksheet to the renewal conversation. Vendors negotiate on line one; the worksheet moves the conversation to lines two and six.

Triple Whale alternative for a one-off attribution read is the same comparison for the most common SMB case.
