Overview

Built as an official Square partner product, PayOS wraps Square Restaurant POS with Stampede's guest platform. In-venue payments, deposits, and pre-orders all enrich a single profile; loyalty attaches to the payment card; marketing workflows fire at bill closure.

How it works

Square processes the payment (with full Square security); PayOS captures the transaction metadata (spend, line items, venue, timing) onto the unified guest profile. Events (bill closed, card linked, reward redeemed) become triggers for workflows and data for analytics.

Goal	Start here
Square Restaurant POS integration	PayOS integrates with Square Restaurant POS as an official partner — no middleware, no manual reconciliation.
In-venue payments & bill closure	In-venue payments run through Square with full security; PayOS layers on structured guest data and triggers downstream workflows at bill closure.
Deposits & pre-order payments	Deposits and pre-order payments flow through PayOS at booking time, cutting no-shows and helping kitchens prepare.
Payment card linking	Card linking attaches loyalty rewards and personalised offers to the payment card itself, so redemption is automatic at checkout.
Automatic discounts & reward redemption	Rewards and discounts are applied at checkout automatically based on the guest's profile, loyalty status, and any active campaigns.
Guest profile enrichment	Every closed bill enriches the guest profile with spend, line items, visit time, and venue — turning payments into marketing signal.
Workflow triggers	Bill closure, card linking, reward redemption, and spend-tier changes fire events that can trigger any Marketing workflow in real time.
ROI & revenue analytics	PayOS analytics connect campaign activity directly to Square sales — so ROI is measured on realised revenue, not proxies.
Onboarding scenarios	PayOS onboarding meets you where you are: existing Square merchants, migrating venues, and brand-new setups each have a path.

Core concepts

Bill closure

the event that settles a bill and emits a guest-level record.

Card-linked

Workflow trigger

real-time event that enrols a guest into a journey.

Usage & workflows

In-venue payments, deposits for reservations, pre-orders, card-linked rewards, post-visit campaigns.

Example

A guest pays via Square; PayOS writes the transaction to their profile; a "thanks for visiting" review-request SMS is sent 24 hours later through a Marketing workflow.
