Understanding Where Public Sector Opportunities Are Managed
If you are new to public sector bidding, one of the first things you will quickly realise is that there is not one single procurement portal used across the UK. Instead, there are multiple procurement platforms, eTendering systems and supplier portals used by different public sector buyers to advertise and manage opportunities.
For suppliers, this can initially feel overwhelming. You may locate an opportunity on one website, register interest on another platform, and then submit your response through a completely different portal.
Understanding how procurement portals work is therefore an important part of becoming genuinely bid ready. As discussed in our Is Bidding Right for Your Business? blog, preparation and structure are fundamental to long-term bidding success.
In this guide we explain:
- the main procurement portals suppliers should understand
- examples of who uses them
- the difference between notice platforms and eTendering systems
- why some buyers operate their own portals
- how suppliers can avoid missing opportunities
Procurement Notice Platforms vs eTendering Systems
A common misconception among suppliers is that all procurement portals serve the same purpose.
In reality, there are usually two separate layers:
(1) Procurement Notice Platforms
These are used to advertise opportunities publicly.
Examples include:
- Find a Tender Service (FTS)
- Contracts Finder
- Public Contracts Scotland
- Sell2Wales
These platforms are primarily designed to help suppliers locate opportunities and monitor the market. See our Finding Bid Opportunities that are Right for Your Business for more information on these platforms.
(2) eTendering / eSourcing Platforms
These are the systems used to actually manage the live procurement exercise.
Examples include:
- ProContract
- In-Tend
- Delta eSourcing
- Jaggaer
- BravoSolution
- OPEN
- Atamis
These are the systems where suppliers:
- download tender documents
- submit clarification questions
- upload responses
- complete pricing schedules
- receive procurement communications
As explained in our Central Digital Platform (CDP) blog, Find a Tender now acts as the “front door” for UK public procurement notices under the Procurement Act 2023, but suppliers will still need accounts across multiple eTendering systems to actually participate in opportunities.
ProContract (Proactis)
One of the most widely used eTendering systems across UK local government is ProContract, operated by Proactis.
This platform is heavily used across:
- Local Authorities
- Housing Associations
- Combined Authorities
- Blue Light organisations
- Education providers
Examples of procurement hubs using ProContract include:
- London Tenders Portal
- regional procurement partnerships
- multiple county and metropolitan councils
For many suppliers targeting local government contracts, ProContract is one of the most important platforms to register on early.
Suppliers can:
- create supplier profiles
- configure alerts
- download documentation
- submit tenders electronically
- manage clarification questions
Because so many authorities use ProContract, it often becomes a core part of a supplier’s ongoing bid pipeline strategy.
Delta eSourcing
Delta eSourcing is another major procurement platform widely used across the UK public sector.
It is commonly used by:
- Councils
- Universities
- Housing providers
- Utilities
- Central Government bodies
Delta is often used for:
- framework procurement
- Dynamic Purchasing Systems (DPS)
- supplier engagement
- tender management
Many authorities have migrated procurement activity onto Delta over recent years, meaning suppliers increasingly encounter it during public sector procurement exercises.
As discussed in our Framework Agreements & DPS Explained blog, suppliers pursuing frameworks and DPS opportunities will regularly encounter systems such as Delta during qualification and call-off stages.
In-Tend
In-Tend remains one of the most established procurement systems in the UK public sector market.
It is particularly common within:
- Local Government
- Education
- NHS-related procurement
- Housing
- Shared procurement services
Suppliers can use In-Tend to:
- register interest
- complete online questionnaires
- upload submissions
- communicate with buyers
- receive procurement notifications
Many councils still rely heavily on In-Tend for day-to-day procurement activity, especially for below-threshold and regional opportunities.
Jaggaer & BravoSolution
Jaggaer is a major enterprise procurement platform used widely across:
- NHS organisations
- Central Government
- Universities
- Utilities
- Research institutions
Many older BravoSolution portals now operate within Jaggaer infrastructure.
These systems are commonly associated with:
- large-scale procurements
- framework management
- complex regulated procurement exercises
- national commissioning activity
Suppliers targeting central government and NHS contracts will regularly encounter Jaggaer-based systems.
OPEN Procurement
OPEN is another procurement system increasingly used across:
- Local Authorities
- Housing providers
- regional commissioning environments
- community-based procurement
Like other systems, OPEN allows suppliers to:
- register interest
- access documentation
- complete online responses
- manage clarifications
Different authorities configure OPEN differently, meaning supplier experience can vary between buyers. May buyers have shifted from ProContract over to OPEN in recent months/years.
Atamis
Atamis has become increasingly prominent within:
- NHS procurement
- supplier management
- contract management
- central government procurement
The NHS in particular has expanded its use of Atamis significantly in recent years.
Suppliers may encounter Atamis during:
- NHS framework applications
- supplier onboarding
- contract reporting
- procurement pipeline management
Individual Commissioner Portals
One important thing suppliers must understand is that many public bodies operate their own branded procurement portals.
For example:
- councils may operate their own supplier portals
- universities may have dedicated procurement systems
- NHS Trusts may configure their own Jaggaer environments
- housing associations may use bespoke procurement hubs
This means suppliers often require multiple accounts, even where the underlying software provider is technically the same.
As explored in our Public Sector Buyers blog, different commissioners procure differently, use different systems, and often evaluate suppliers in different ways. Understanding this landscape is a key part of effective bid strategy.
Common Mistakes Suppliers Make
(1) Registering too late
Many suppliers only register on procurement portals after finding a live opportunity.
This creates unnecessary pressure because:
- accounts may require approval
- passwords fail
- supplier information is incomplete
- upload issues occur close to deadlines
(2) Failing to configure alerts
Most platforms allow suppliers to configure:
- keyword alerts
- CPV code alerts
- geography filters
- sector notifications
Without these, suppliers can easily miss relevant opportunities.
(3) Chasing every portal equally
Strong suppliers focus on the platforms most relevant to:
- their target buyers
- their geography
- their sector
- their service offer
This creates a much more manageable and strategic pipeline.
How Evolve Can Help
At the Evolve Network Group, we regularly support organisations with:
- procurement portal setup
- bid readiness
- pipeline strategy
- framework targeting
- opportunity qualification
- tender submissions
Many suppliers lose opportunities simply because they:
- were not registered correctly
- missed alerts
- misunderstood procurement routes
- failed to monitor the right portals
A strong bidding strategy begins long before the tender response itself.
