A statement from Doshii said Abacus, Splitability, and MSL (SwiftPOS and Infogenesis) would be able to use Doshii's growing range of ordering, delivery, reservation, loyalty program, payment, rostering and other business apps.
Doshii chief executive Justin O'Donnell said: "These new partnerships will enable hospitality businesses to use Doshii to connect and sync with a multitude of information software platforms and apps needed to run a hospitality business, all through their partnered PoS systems.
"Doshii effectively creates an integrated 'one-stop-shop' for all the home delivery and in-venue ordering, business management, data, and customer loyalty program apps with the venues' PoS system.
He claimed the new partnerships would reduce development, maintenance and support expenses as the new partners could use Doshii as an integration provider, along with round-the-clock monitoring and support.
"Giving our partners' venues access to the Doshii ecosystem ultimately enhances the increasingly tech-savvy consumer experience – and happy customers lead to a more successful hospitality business," he said.
"Doshii also has a full menu management system to allow venue operators to manage their menus from a central platform. All styles of hospitality operator will benefit from less time managing menus across multiple apps.
"We have experienced unprecedented uptake following last year's COVID-19 restrictions, largely due to Doshii's ability to help venues seamlessly 'tech up' and allow businesses to focus on what they're actually good at – be it making and serving burgers or mixing cocktails – without distraction or delay."
The partnership will enable the new partners to connect directly to Deliveroo, Mr Yum, OrderUp and Mobi2Go, along with their existing partner me&u, and reservations apps including OpenTable and Resy.
O'Donnell said: "These new partnerships will help venues achieve this, while also allowing them to digitally manage their menus via Doshii."
