I would be happy to provide you with some assistance if you can be more precise in terms of what type of logistics operation it is.
The Logistics and Supply Chain Consultants within my team, all of whom have a background of working with or for Transport and Logistics Service Providers, have significant experience in developing the scope of the logistics outsourcing tenders to cover all operational and service requirements; managing the tender process form beginning to end, from writing the scope to response evaluation and final negotiations for Global, European and UK based Multi-modal Transport and Distribution logistics, warehousing and freight tenders.
Our Logistics outsourcing projects include the following:
• UK e-fulfilment for Beautique.com.
• Global Multimodal Freight and Landside Logistics and transport for Triumph Motorcycles.
• European Distribution and ‘Last Mile’ delivery for Triumph Motorcycles.
• Parts and Materials Warehousing and Distribution for Wales & West Utilities.
• UK Home Delivery Logistics Network and Distribution for IKEA.
• UK frozen Logistics and Distribution Networks for Quorn.
• Bulk Food Waste Collection and UK transport operations for Biogen (UK).
• Benelux frozen Logistics and Distribution Networks for Quorn.
• Southern Warehouse and Distribution Centre for Premier Foods.

No single rule applies. It would depend upon the kind of customer that you are talking too (unless you are an integrator offering standardized services).
