Square–OpenTable and Toast–Resy Integrations Move Guest Data to POS

The boundary between POS and reservation systems in restaurant technology is narrowing. With the new integrations announced on August 18, 2026, Square–OpenTable and Toast–Resy have begun to more directly transfer guest information collected during reservations to service and payment processes.

According to Nation’s Restaurant News, the moves by the two major POS providers are seeking solutions to a similar problem: the separation of guest information held on the restaurant's reservation platform from the order and spending data generated in the POS.

Square and OpenTable Deepen Single Customer View

Square expanded its existing strategic partnership with OpenTable on August 18, 2026.

The new structure closely integrates reservation and guest information from OpenTable with Square's transaction and operational data. The operator can evaluate the guest's reservation history and preferences alongside information such as what they ordered and how much they spent within the same customer context. Access to this information is planned from service devices like Square Handheld in addition to Square software.

Square's current support documents show that the existing OpenTable integration synchronizes table plans, service stages, and reservation information with the POS. When the "Seated Status" is open, an automatic check can be opened on the Square side for reservations seated at the table in OpenTable; the reservation deposit can also be applied to the final bill in certain configurations.

Thus, the August announcement is not a brand new integration; it is a deepening of the existing connection on the guest and spending data side.

Toast and Resy Bring Information to the Server's Handheld

On the Toast–Resy side, the focus is directly on the staff during service.

The Digital Chits integration announced by Resy on August 13, 2026, allows guest notes, preferences, past visits, special occasions, and specific tags stored in the Resy Guestbook to be displayed on Toast POS terminals and handheld devices.

According to Resy's technical documentation, the system can transfer reservation context such as special occasions, VIP tags, guest tags, and visit information to the screen where staff take orders. The goal is to reduce the need for service staff to look at a separate reservation screen or use printed notes.

Toast's own support page also confirms that the existing Resy integration associates reservation, live table status, and guest behavior data with the POS.

Common Goal: Linking Reservations to Spending

The industry significance of these two integrations is not just the competition between technology companies.

Restaurants have held the answer to the question "who is coming?" on the reservation platform for years, while the POS system has held the answer to "what did they purchase?".

When these data sets remain disconnected, the business's customer profile becomes incomplete.

A guest's frequency of visits per month can be seen in the reservation system; however, their preferred wine, average spending, or which menu categories they gravitate towards may remain on the POS side.

Bringing this information together can create a more usable profile from a CRM, loyalty, and marketing perspective. However, to measure the real commercial impact of this, businesses need to not only collect data but also convert it into the right actions.

Service Team's Screen Switching Burden May Decrease

There is also a tangible counterpart to the integrations on the employee side.

In busy service, the host, waiter, and manager switching between separate reservation tablets, POS screens, and written notes can create time loss.

For example, if a guest's shellfish allergy is recorded in their reservation profile, it is not enough for this information to remain only on the host's screen. It needs to reach the service staff at the right time.

The Resy–Toast integration particularly focuses on this point. The Square–OpenTable side also aims for a similar flow by moving reservation data to Square's service devices.

However, automation does not eliminate employee responsibility. In critical information such as allergies, staff must verbally confirm and maintain the business's standard procedures.

More Integrations May Create More Platform Dependency

Another point highlighted by NRN is the tighter connections between the two POS providers and different reservation ecosystems.

The deepening relationships between Square–OpenTable and Toast–Resy may provide better integration for restaurants; however, it may also tie technology choices together.

When a business changes its reservation system, it must now evaluate not only the monthly subscription or per-reservation cost but also which data is transferred bidirectionally with the POS.

For example:

• Is table status synchronized in real-time?

• Is the deposit automatically applied to the account?

• Are guest preferences visible on the service device?

• Is purchase history written back to the reservation profile?

• Can data be exported?

• If the system is changed, is customer history preserved?

The last question is particularly important. While integration provides convenience, the business must not become overly dependent on a single ecosystem for critical customer data.

Data Access Requires Employee Training

Moving guest information to more employees' screens creates opportunities for personalized service but also brings new responsibilities regarding privacy and authorization.

Information such as VIP status, special occasions, past visits, or dietary preferences should only be used for the purpose of "good service".

Businesses should clearly define which employees have access to which data, how long this information is retained, and how employees should behave with customer information.

Having good technology integration does not automatically mean good data governance.

Stafflink's View

In our opinion, the real value of the Square–OpenTable and Toast–Resy moves for restaurants is not to collect "more customer data" but to be able to bring existing information to the right employee at the right moment.

If a waiter needs to check three different screens during busy service, as the number of technologies increases, operations may become more complicated rather than easier. When reservation information, table status, deposits, and order history enter the same workflow, integration begins to generate real operational value.

However, restaurants need to evaluate not only the feature list in their technology selection but also data portability, integration costs, employee training, and platform dependency together.

The future of restaurant technology will likely not be more independent screens; it will shape around systems that can show the guest journey from reservation to payment within a single context.
