## From bill of quantities to offer, without retyping or surprises

### The crbx, the PDF and the contract do not always agree

After the award it is too late. Ziva lists each finding with line item and source and drafts questions while the forum is open.

Screenshot: Bill of quantities check in Ziva: findings on line items and contract documents, each linked to its source.

### Unit prices are your craft. Retyping is not.

Ziva carries line items and quantities into an Excel workbook with formulas. Assumptions stay yellow until you set prices.
