Enter measurements, openings and waste allowances. Calculate quantities and material costs for paving, painting, flooring, tiling and plastering.
Add labor, transport and other project costs. Keep internal costs separate from customer pricing.
Use Pro for quote versions and PDF export. Review the details, then choose where to share the file.
A PRACTICAL WORKFLOW
Use metric or US customary units and EUR or USD for each project. Estimates depend on the measurements, material information and prices you enter.
Both audience pages lead to the same KlusSom iPhone app. The professional workflow uses optional KlusSom Pro features.
KlusSom focuses on project calculations, customer pricing and quotes. It does not promise invoicing, payment collection, scheduling or team collaboration.
Projects are stored locally on your device. Calculations work offline; buying or restoring Pro requires an App Store connection. See KlusSom privacy.
Verify measurements, supplier packaging, material requirements, prices and applicable tax rules before ordering or issuing a quote. Tax rates are entered manually; KlusSom does not look up local tax rules.
