Online retailers in the UK are on course to dispatch a record 900 million orders, or 930 million parcels in 2014, according to the latest IMRG MetaPack Delivery Index.
The predicted lull in online retail occured in August with orders down 13.6% month-on-month. However, this still represents a cumulative growth rate year-on-year of 20%.
Based on past e-retail delivery patterns, order volumes are expected to increase by 10% and steadily grow in the run-up to Christmas, the report said.
IMRG head of e-Logistics Andrew Starkey said: "With three years of data in the Index we can now predict the annual pattern of when and where these deliveries will be made. This means we can confidently anticipate that a record 120 million orders will be dispatched by UK retailers in December alone."
The Index also revealed that delivery service performance improved during August with close to 94% of deliveries on time which is higher compared to the same period for the last two years.
Overall, the proportion of orders either late or not delivered at the first attempt was 10.72% in August compared to the monthly average of 11.6% over the last 12 months.
Starkey added: "Quality of service is higher this August than in the previous two years which bodes well for the peak period. Some delivery problems relating to address queries seem to be on the rise so retailers need to keep an eye on this."
