## Summary

Chicago can make supplier development more practical by measuring invoice and subcontractor payment time.

## Thesis

- Supplier development is incomplete until payment time is measured and visible.
- Small firms experience late payment as a finance constraint.
- Chicago can turn existing payment data into a working-capital tool for neighborhood vendors.

## Chapters

### 01. The clock

Payment time turns supplier diversity into an operating standard.

A public contract becomes development only when the vendor can convert delivery into usable cash. The payment clock should be visible from invoice receipt through subcontractor pass-through.
