Waterstones is grappling to stock its shops and fulfil a backlog of online orders after problems with its new warehouse tech systems sparked product shortages.

The national bookshop chain upgraded to software from Blue Yonder in July but has been beset with issues, which were first reported by The Guardian.
Waterstones apologised for âthe unusual slownessâ in fulfilling online orders and said it expects to clear the backlog by next month.
A spokesperson for the retailer said: âWaterstones last month upgraded the system that manages stock distribution from our warehouse to Blue Yonder technology. This is now operational, with stock flowing to our bookshops and customers.
âOver the implementation period, however, a backlog of orders was created which we are now processing as quickly as we can.
âBy September we anticipate beginning to benefit from the much more sophisticated platform now at our disposal.â
However, Waterstones admitted that not all of its stock issues were sparked by the switch to Blue Yonderâs system. The retailer said that it had âunder-boughtâ some books â perhaps suggesting a more cautious approach to stock control in the current economic climate.
The spokesperson added: âWe note some of the public commentary, much of which complains that we have under-bought some titles.
âUnfortunately, no amount of sophisticated new warehouse systems changes the fact that as booksellers we choose what to buy, sometimes being a little too reticent, sometimes too enthusiastic. We canât blame Blue Yonder for this.â
The issues were first raised on Twitter by Sam Missingham, publishing commentator and founder of The Empowered Author book marketing service, prompting a string of replies from authors, staff and customers.
One employee tweeted that Glasgow âran out of booksâ completely as a result of the problems, while another said: âOur systems for deliveries and order processing were super-outdated. They were upgrading them and something has gone wrong, so orders are not matching up properly on the system and as a result, we havenât been able to get any books whether theyâre stock or for customers. Nightmare.â
