Choosing between eSourcing providers.
An eSourcing provider gives you the software - and sometimes the people - to run competitive buying online. This is a practical buyer's guide to what UK eSourcing providers do, the features that matter, and the questions to ask before you commit. It also shows where eSourcingData is different.
What does an eSourcing provider do?
An eSourcing provider supplies the platform that runs your competitive buying online: publishing requirements, inviting suppliers, collecting structured responses, evaluating them and recording every decision. The better providers also cover contract management and give you a complete, exportable audit trail as a matter of course.
Providers differ in three ways that matter. First, sector: some are built only for the public sector, others only for private enterprise. Second, compliance: many platforms were built for PCR 2015 and retrofitted for the Procurement Act 2023, rather than designed for it. Third, support: some sell you a login and leave you to it, while others pair the software with procurement specialists who can set it up, train your team, or run exercises for you.
eSourcingData is an eSourcing provider that covers all three: source-to-contract software built for PA23 from the ground up, used across public sector, private sector, consultancy and charity work, with hands-on support available whenever you want it - for a single organisation or across many client accounts.
What to look for in an eSourcing provider
Full source-to-contract coverage
RFQ, ITT, tender, evaluation, award and contract management in one place - not just the sourcing step.
Genuine PA23 support
Built for the Procurement Act 2023, with transparency notices, the Competitive Flexible Procedure and standstill in the workflow - not a bolt-on checklist.
A defensible audit trail
Every notice, question, score and document captured automatically, so awards stand up to challenge.
Multi-client capability
Separate client or department accounts from one platform - essential for consultancies and shared services.
Fair evaluation tooling
Independent scoring, moderation and automatically generated evaluation reports.
Support, not just software
Managed setup, training and the option of outsourced procurement if you want exercises run for you.
