# Integrations | What OPPI Connects To > Every way into OPPI. One sign-in APIs for Square, Lightspeed Restaurant, Deputy and Tanda. The OPPI Tether for legacy tills. A signal layer of weather, events, traffic and calendars that needs no connection at all. Canonical URL: https://oppi.au/integrations Site index for agents: https://oppi.au/llms.txt --- Integrations ## No rip. No replace. OPPI joins your stack. OPPI connects to a hospitality venue's existing systems, Square and Lightspeed Restaurant on the tills, Deputy and Tanda on the roster, Google Drive and Notion in the workspace, brings legacy tills in through the OPPI Tether hardware bridge, and gathers weather, local events, road traffic and holiday calendars around the venue on its own. [Book a demo](https://oppi.au/demo) [See what connects](#connections) Three ways in 01 ### Your systems' APIs One sign-in each Square, Lightspeed Restaurant, Deputy, Tanda, Google Drive and Notion connect with one sign-in. The tills are re-read every 15 minutes; rosters, timesheets and staff sync on their own cadences. Nothing to install, nothing to maintain. 02 ### The OPPI Tether For legacy tills A small bridge for the till that predates the cloud. It reads the machine locally, scrubs anything personal, and sends the day over encrypted HTTPS into the same model a cloud POS feeds. The old hardware stays; the blindness goes. 03 ### The world outside No connection needed Weather, local events, road traffic, public holidays and school terms arrive on their own. OPPI discovers and verifies them around your address, so the model knows about the wet Tuesday and the stadium crowd without you connecting a thing. The three channels 01/03 One model · every door in · nothing written back What connects today ### The honest ledger. Every row wears its status. Connected means a working pipeline, today. In build means the adapter is on the bench, and we say which is which. Point of sale 1. 01 #### Square Connected Payments, orders, line items and the catalogue, re-read every 15 minutes. 18 months of history backfilled on connection. 2. 02 #### Lightspeed Restaurant (K-Series) Connected Orders and the menu, on the same 15 minute cadence and the same backfill driver. 3. 03 #### OPPI Tether Connected The bridge for legacy tills. Revenue, payments and items from hardware the cloud never met. 4. 04 #### Toast In build Orders and payments through the same adapter pattern. Running a Toast venue moves it up the queue. 5. 05 #### Clover In build Same adapter pattern, same model at the end of it. 6. 06 #### TouchBistro In build Same adapter pattern, same model at the end of it. Workforce 1. 01 #### Deputy Connected Staff, areas, rosters, leave and timesheets, wage rates included. Rosters read 28 days back and 14 days forward. OPPI never overwrites what you own. 2. 02 #### Tanda Connected Timesheets today, with costs, award tags and leave flags. Roster and staff sync are still in build, and we say so. 3. 03 #### 7shifts In build The adapter is already half built. Rosters and timesheets land the same way Deputy's do. 4. 04 #### Humanforce In build Rosters and timesheets through the same three-pillar sync. 5. 05 #### Employment Hero In build Rosters and timesheets through the same three-pillar sync. Documents & workspace 1. 01 #### Google Drive Connected Your venue's documents, read where they already live. 2. 02 #### Notion Connected Pages and databases, connected through MCP. The signal layer · nothing to connect 1. 01 #### Weather Connected Forecast to 16 days, a seasonal outlook to 46, and fourteen months of local history for calibration. 2. 02 #### Local events Connected Discovered around your address and verified with citations, assessed up to a year out. 3. 03 #### Road traffic Connected Travel times on the routes that bring people to your door, read every 30 minutes. 4. 04 #### Calendars Connected Public holidays, school terms and paydays, state by state. Under the hood ### Built to add vendors, not exceptions. 1. 01 #### One adapter per vendor Every vendor lives behind its own adapter, and adding one changes nothing in the core. OPPI stays deliberately blind to whose data it is reading. 2. 02 #### Raw first, truth second Every sync lands raw, then refines into one clean model of the venue. Nothing is ever written back to the source, and everything traces back to it. 3. 03 #### Polite by design Syncs honour every vendor's rate limits and back off when asked. Your POS never notices OPPI is there. ### Don't see yours? Then it isn't on the bench yet, and we won't pretend otherwise. A new vendor is one adapter, not a rebuild: for cloud systems with clean APIs, connecting is days of work, not months. Tell us what you run and we'll give you a date, not a maybe. [Tell us your stack](https://oppi.au/contact) Questions Which POS systems does OPPI work with? Square and Lightspeed Restaurant (K-Series) connect today, one sign-in each, re-read every 15 minutes. Toast, Clover and TouchBistro are in build. Older or on-premise tills connect through the OPPI Tether, a small bridge that reads the machine locally and feeds the same model. Does OPPI work with my rostering system? Deputy connects in full: staff, rosters, leave, timesheets and wage rates, read 28 days back and 14 days forward. Tanda connects for timesheets today. 7shifts, Humanforce and Employment Hero are in build. What about my accounting software? Not yet. Accounting connections are designed but not shipped, and OPPI's cost picture today comes from your POS and your plans, not your ledger. When that changes, this page will say so. My till is ancient. Am I out? No. The OPPI Tether is a small bridge for exactly that machine. It reads the till locally, scrubs anything personal, and sends the day over encrypted HTTPS into the same model a cloud POS feeds. Do I need to connect anything for weather or events? No. The signal layer needs no connection. Weather, local events, road traffic, public holidays and school terms are gathered and verified around your venue's address automatically. The tools stay. The blindness goes. Bring your POS to a 30 minute demo and watch OPPI read it.
