How to Tell Whether Your POS Can Track Marketing Revenue

Your POS can confirm what was sold, when it was sold, and how much the guest paid. It can track revenue from a marketing campaign only when the campaign response is connected to an identified guest and that same guest is connected to a settled check.

That is why asking whether Toast, Square, Clover, or another POS “has attribution” is not enough. The important question is whether the complete campaign-to-check connection works in your restaurant's actual setup.

A POS records the sale, not automatically what caused it

Imagine that someone sees a Facebook ad on Tuesday and walks in on Friday. The POS records Friday's check. Unless the ad created an identity that survived until the visit—a reservation source, offer claim, unique code, or another permitted guest record—the POS cannot know that the Tuesday ad influenced the sale.

Native email, loyalty, and online-ordering reports may attribute sales according to the POS provider's own rules. That can be useful, but it is different from proving that an outside ad, influencer post, or direct-mail piece produced a specific check.

Keep those claims separate:

Platform-attributed sales follow the platform's attribution rules.
Matched sales connect a campaign response, identified guest, and settled check.
Observed lift compares sales or traffic during a campaign with a relevant baseline.
Incremental sales require credible evidence of what would have happened without the campaign.

Ask how campaign identity reaches the check

Before buying a POS or attribution product, ask the vendor to explain one real path from start to finish:

Where is the campaign identified?
How does the guest become identifiable?
How is that identity recognized during the visit or order?
Which POS record confirms that the check was paid rather than opened, voided, or refunded?
Can an authorized user trace one result back to the original campaign without guessing from the date or amount?

A vague answer about dashboards is not the same as a working connection. You want to see a campaign response become a completed check in the same restaurant configuration you will use.

A supported-POS logo is only the beginning

An integration page can tell you that two systems connect. It does not tell you that every location, ordering channel, loyalty setup, and guest-identification method sends the same fields.

Confirm what the integration can read and match in your environment:

settled transaction status;
location and service time;
net sales after discounts and reversals;
a permitted guest key;
the campaign or offer identity attached to that guest;
whether online ordering, in-store dining, and third-party delivery follow different paths.

Feast's public materials list Toast, Square, and Clover as supported POS systems and describe a campaign-to-POS matching path. That does not mean the three POS systems expose identical data in every configuration. The implementation still needs to be checked against the restaurant's real checkout flow.

Verify the number before you trust the report

Use an authorized campaign response and a real or permitted test transaction. Confirm that the guest identity reaches the correct settled check, then confirm that a void or refund is handled correctly. Redact customer information from any screenshot or report used outside the restaurant's private systems.

Once the connection works, measure match coverage: how many identifiable campaign responses became matched checks, and how many could not be reconciled? A matched-sales total without the unmatched count can look more complete than it is.

The best POS is the one that fits operations and preserves the connection

Marketing attribution should not be the only reason to select a POS. Reliability, payments, menu management, online ordering, reporting, support, and staff workflow all matter.

For marketing, choose the system and integration that can preserve campaign identity through the guest journey you actually use. A reservation-led restaurant may need a strong booking connection. A counter-service restaurant may depend more on offer claims, loyalty identity, or online ordering.

The POS does not have to solve the whole problem alone. It does have to provide a trustworthy record of the completed sale so the attribution layer can connect marketing to revenue without inventing the answer.
