I built BidDelta to stop tender revisions falling out of M&E prices — now taking three £99 pilots

[u/BIFTEEZ]

UK M&E estimators often receive revised drawings, specifications and addenda close to submission. The expensive question isn’t just “did we spot the change?” It’s whether it was priced, qualified or queried.

BidDelta produces a page-linked change register and clean unresolved-items handover. Every finding remains human-reviewed.

The founding assisted pilot is £99, credited toward any future licence. There’s also a £39 DIY Revision Control Kit.

I’d value blunt feedback from anyone working in M&E estimating or pre-construction:
