DTC orders often include just one single unit or one of multiple different items so stock needs to be stored in a way that it is easy to access individual units as quickly as possible. The stock will also turn over more slowly as the orders have fewer items, therefore it may be prudent to store smaller volumes with a DTC fulfilment partner. Distance between SKUs will also have a direct impact on the efficiency of the operation as there may be multiple picks per order with a much lower order value making every minute count.
