Just Eat Takeaway delivered 408.3 million orders in the first nine months of 2020.
Shareholders approved the firm's £5.6billion purchase of Grubhub last week.
Australia has the fastest percentage growth in orders, rising by triple-digits.
Food delivery giant Just Eat Takeaway said new partnerships with McDonald's and Greggs in the UK helped it to deliver millions more orders in the last quarter.
Global bookings at the Dutch-based firm also shot up above 150 million as it continued to take advantage of lockdown measures that have impacted hospitality venues and encouraged more people to buy their food and drink online.
Orders in Canada nearly doubled from July to September compared to the same period last year while there was a 47 per cent rise in Germany, the group's second-largest market.
It means it has sold 408.3 million orders in the first nine months of 2020, an increase of 110 million from the previous year's levels. Just Eat said Australia registered the fastest percentage growth of any country, with a triple-digit upsurge.
The UK was responsible for about 30 per cent of total demand and saw orders grow by 14 million to 46.4 million in the last quarter against July to September 2019.
Just Eat attributed part of the immense expansion to new delivery deals it signed in January with McDonald's and Greggs.
The tie-up with Greggs is an exclusive partnership that prevents rivals Uber Eats and Deliveroo from providing the chain's famous baked products such as vegan sausage rolls and steak bakes.
There were concerns though that the Eat Out to Help Out scheme would take business away from dot-com takeaways in August. The initiative offered patrons a 50 per cent discount on food and soft drinks up to £10 in hospitality venues.
But despite visitors claiming more than 100 million meals at restaurants, pubs and bars under the scheme, Just Eat said its orders that month were not dented.
Chief executive Jitse Groen said that the uplift in sales has allowed the business to enlarge the gap between them and their competitors.
'We have continued to generate strong adjusted EBITDA, while investing aggressively, and are well-positioned for autumn and winter, our traditional growth season,' he added.
Just Eat Takeaway.com has been on a buying spree of rivals in recent years as it seeks to become one of the world's leading takeaway companies.
Shareholders approved its £5.6billion purchase of Chicago-based Grubhub last week. The deal would make Just Eat the largest digital food delivery firm outside of China and is expected to be finalised in the first half of next year.
Uber Eats had initially intended to buy Grubhub, but US regulators expressed anxiety that the deal would create a de facto duopoly in the American app-based takeaway industry.
Russell Pointon, Director of Consumer and Media at Edison Group, said that the mix of escalating orders in major markets ' will encourage investors that the firms' recent $7.3billion deal for GrubHub can lead to further seamless growth.'
He warned though that 'such a high-profile acquisition and rapid growth represents a double-edged sword as the firm will have to rely on organically expanding with what they have as increased regulatory scrutiny is likely to slow down any further M&A attempts.'
Shares in Just Eat Takeaway were up 6 per cent to £93.70 at around 4:15pm.
