British fashion retailers will switch their spending firepower to technology from the high street in 2017 after online shopping became the key driver of sales growth over the all-important festive period.
Marks & Spencer is investing in apps, its website and logistics, while spending 350 million pounds (S$618 million) over five years to close 10 per cent of clothing and home space.
Department store John Lewis said it was cutting staff bonuses in part to enable it to invest in its online operations after 40 per cent of its Christmas sales came from the web.
And Next, which failed to keep up with rivals for a second Christmas in a row, will spend 10 million pounds to improve its online operations and marketing.
"They will have to invest in infrastructure and it will weigh on margins, but if you get it right you have a profitable online business," said one large institutional investor in UK retail who asked not to be named due to company policy. "And you can engage on multiple platforms."
The renewed drive in technology comes as British web-only players ASOS and Boohoo continue to race ahead, helping Britons to embrace online shopping more quickly than their European cousins.
And the pressure is relentless. ASOS, with nearly 5 million active users in the UK, said it would increase its own capital expenditure to keep ahead of the pack after it posted 18 per cent UK sales growth in the four months to the end of the year.
Boohoo grew British sales by 31 per cent in the same period.
Online sales have been booming in Britain for years, with ecommerce accounting for nearly a quarter of all purchases in December, according to the British Retail Consortium.
In the 52 weeks to Dec. 18, overall fashion sales fell 2 per cent, according to market research firm Kantar Worldpanel, while pure online players grew 7 per cent as fashion lovers snapped up goods through simple apps on their mobile.
While trading updates show that traditional retailers grew their sales by selling additional goods to customers picking up online orders in store, the move online also brings new challenges such as the high number of goods that are returned.
The signs of the change can be seen across the country, on small high streets where independent shops have shut - hurt by high business rates - and on the stock market where the share price of Boohoo has jumped by 500 per cent in two years.
Pick-up lockers at railway stations and petrol pumps mean parcels can be picked up at any time, while changing rooms in standalone sites in the centre of towns allow purchases to be tried on and instantly sent back if not wanted, making it as easy to shop online as it is to wander down a high street.
The industry estimates that around 30 per cent of womenswear items bought online are returned.
Traditional retailers have harnessed the web by persuading customers to pick up online-ordered goods instore, forcing firms to speed up delivery logistics and increase storage space in their shops. "The role of the shop does change," said Charlie Mayfield, chairman of the employee-owned John Lewis Partnership.
"We are still opening shops but we will be opening fewer going forward and we will be investing more in changing existing shops so they can fulfil that different role more."
The 133-year-old Marks & Spencer, which has struggled for years to grow its clothing business, beat forecasts for Christmas trading as investment in its app for iPad and mobile devices helped boost online sales.
More than 60 per cent of all goods sold online were picked up in store - known as click and collect. Seeking to adapt the business to meet the new demand, its said in November it would not return additional cash to shareholders in the second half.
Debenhams, Britain's No. 2 department store chain, also beat forecasts as those customers shopping online and in-store spent about two and a half times more than a shopper in one place.
The group, which appointed Sergio Bucher as CEO in October, is set to unveil its plans for the future in April and analysts at Liberum have said that could entail higher spending.
And Britain's biggest department store John Lewis, one of the leading retailers online over the last 15 years, said it would speed up its internet strategy after 40 per cent of its Christmas sales came from the web, up from 36 per cent last year.
"You might have expected to see a slowdown in the rate of growth but it has basically continued on the same trajectory,"Mayfield said. "And we've got very good data which shows the relationship between shops and online sales is strong." But the cost to transform the business is clear, with operating profit down 31 per cent in the six months to end July.
John Lewis said trading profit would come under pressure this year and the need to invest, plus the weaker pound, meant staff bonuses would be "significantly" lower.
Thomson Reuters data shows that 2017 full-year pretax profit at M&S and Debenhams is also expected to fall around 18 and 12 per cent respectively.
Despite the high costs, the experience of retailer Next shows that the big names have little choice but to follow their online peers if they want to remain competitive.
Next will invest to improve its website and online marketing in a recognition that it may have fallen behind the standard of some competitors, where sites carry more content including video and numerous photographs to show how an item would look.
"If it's not convenient and the check out process is not good or you don't portray the product in the right way, then people will just open up another app and order somewhere else,"the institutional investor said. "It's as simple as that these days."
