Replacing PCS and PCS-Tender: what we know about S2C

The Scottish Government is replacing Public Contracts Scotland and PCS-Tender with a single system, known as Source to Contract (S2C). Heads of procurement are reasonably asking whether to wait for it before changing anything else. Here is what has been said publicly.

What is being replaced

Public Contracts Scotland is the national portal for advertising contract opportunities. PCS-Tender provides eSourcing, including eTendering, contract management and supplier performance management. The plan is for one system covering registration for buyers and suppliers, procurement notices, full eSourcing, and contract and supplier performance management.

The timeline so far

• July 2025: the Supplier Development Programme reported that a Prior Information Notice had been published and that a project steering group had been set up.
• January 2026: minutes of the Public Procurement Group and Procurement Supply Group record that the pre-procurement gate was completed with a positive outcome, with an invitation to tender expected in late Q1 2026. They also record that continuity is assured through extensions and dual running.
• The current PCS-Tender contract runs to 29/09/2028.

The same minutes record a request for stronger, regular communication with stakeholders such as heads of procurement. Check the Scottish Government’s latest stakeholder update for the current position.

What it means below the threshold

S2C is a national system for notices and eSourcing. Most below-threshold buying does not go through PCS today: Quick Quote is optional below £50,000, and Public Contracts Scotland records only about 7% of below-£50,000 spend as awards. Whatever S2C looks like, your standing orders, local approvals and the evidence behind each low-value choice remain your organisation’s responsibility.

Waiting for S2C does not close a reporting gap that exists today. The useful question is whether a tool can work alongside whatever comes next.

We have set out what Tenderscape commits to whatever S2C turns out to be, including connecting to its published data when it is available, report exports once signed off, and a break clause tied to your move to the new system.
