The challenge
The client had a trusted, formula-rich Excel costing model but filling fresh input data into it for every job was slow and risky.
What we built
Our automation injects new input data into the client's own template, lets Excel recalculate, and saves a frozen-value output workbook - preserving the client's proven costing logic exactly while removing the manual handling. Each costing run is now consistent and takes seconds.
The result
Before: slow, risky manual filling. Now: seconds per run.
