From spreadsheets to real-time certainty 

Before Chalkstring

Before Chalkstring

✕ We don’t know where the margin stands — it changes daily

✕ Procurement doesn’t match what was actually priced

✕ Variations are buried in emails or tracked in separate files

✕ Valuations are slow, inconsistent and error-prone

✕ Overspends aren’t spotted until it’s too late

✕ Forecasting cost-to-complete is manual guesswork

✕ Everyone’s working in different spreadsheets and systems
