Estimate Creation
Create Estimates Faster as You Scale
Build accurate estimates in minutes using reusable templates and live pricing from your product library. Erro handles calculations, pricing updates, and taxes automatically—so your team can scale without spreadsheets.

Manual Estimating Doesn't Scale
As your business grows, building estimates manually becomes a bottleneck. Copying from old files, updating prices by hand, and managing revisions slows teams down and introduces errors.
Rebuilding From Scratch:Teams waste time recreating similar estimates
Outdated Pricing:Manual updates lead to inconsistent or incorrect estimates
Spreadsheet Dependency:Formulas and tabs become hard to manage at scale
Revision Confusion:No clear way to track or reuse past versions

Template-Driven Estimate Builder
Start every estimate from a saved template. Adjust items, quantities, and configurations as needed while pricing automatically stays in sync with your product library.
Start with Templates:Reuse proven estimate structures instead of starting from scratch
Library-Powered Pricing:Prices update automatically based on your product library
Flexible Adjustments:Change quantities or items without manual recalculation

Automatic Pricing & Tax Calculations
Erro handles all calculations for you. Pricing, totals, and taxes are applied automatically based on your library’s tax profiles and rules.
Automatic Totals:No manual math or formulas to maintain
Library-Based Tax Profiles:Apply the correct tax calculations automatically
Consistent Results:Every estimate follows the same pricing and tax logic

Save, Revise & Reuse Estimates
Save estimate versions, make revisions confidently, or copy an existing estimate to create a new one in seconds.
Save Revisions:Keep a history of estimate updates and changes
Copy Estimates:Duplicate past estimates to speed up new work
Standardized Output:Maintain consistent structure as volume increases
