Our verdict
rTenders vs Delta eSourcing · best fit by use case
Delta eSourcing is primarily a buyer-side portal — you need an account there to submit on many UK tenders, but it doesn't do supplier-side intelligence. rTenders sits next to Delta in your workflow: we find and qualify the opportunities, draft the response, and you submit through Delta (or whichever portal the buyer uses).
Frequently asked questions
Is rTenders a direct alternative to Delta eSourcing?
rTenders covers the same UK tender data sources (Find a Tender, Contracts Finder, regional portals) but adds generative AI for bid writing, fit scoring against your company profile, and automatic PDF tender analysis — capabilities Delta eSourcing does not currently offer.
How does pricing compare?
Delta eSourcing pricing: Free supplier registration; paid alerts add-ons. rTenders: Starter £35/month, Pro £99/month, Business £349/month — transparent self-serve, 20% off annual, free plan on Pro.
Is rTenders ready for the Procurement Act 2023?
Yes. rTenders is aligned with the Procurement Act 2023 (in force 24 February 2025), supports MAT (Most Advantageous Tender) scoring logic, Social Value PPN 06/20, and Net Zero PPN 06/21.
Can I migrate from Delta eSourcing to rTenders?
Yes. You can import your saved searches and pipeline data. rTenders ingests the same FTS + Contracts Finder feeds in real time, so you will not miss any notices during the switch.
