Spreadsheets fail quietly

We get it. Engineers love the flexibility of a spreadsheet. But studies show that nearly 90% of spreadsheets contain significant human or formula errors. Relying on them for pricing and delivering projects is a recipe for never ending verification and remediation.

SpreadsheetProteus
Whoever has the file open has the truthOne shared structure. Everyone sees the same numbers, live.
A formula breaks and nobody noticesCalculations are built into the platform, not typed into a cell.
The bid file and the delivery file are strangersSame work breakdown structure, bid to delivery, automatically.
No record of who changed what, or whenEvery change logged against the project, not buried in a file history.

“We already have a system.” Good. Keep it.

Proteus isn't another ERP or CRM. It's the layer that connects bidding and delivery, so your pipeline and financials stay accurate.

Proteus is very versatile and user-friendly. The tool streamlines our workflow and delivers on all fronts. Knowing there is support to hand if required has been outstanding and gives me confidence and peace of mind. Overall, Proteus is an invaluable tool and it is clear that a lot of thought and expertise has gone into its development. Highly recommended!
Operations

Proteus is a very detailed tool - it allows granular cost variables which is important for teams on differing rates and complex resourcing. This is a proper swiss army knife.
