South African Tender Toolkit
A dashboard-first Excel toolkit that takes you from a tender advert to a defensible decision in about twenty minutes — across nine linked tabs covering Bid Scoring, Pricing, Compliance, Submission and a printable Decision Record. Twelve weighted criteria produce a Bid Score out of 100 with a clear recommendation, a full costing model shows the margin the tender price actually leaves you, and five automatic conflict checks fire when two tabs disagree — so you find out a contract is unprofitable before you spend three weeks winning it.
