DoorWin vs Excel for Window Estimation: Which Is Better?

Drawing Windows

Excel cannot create technical window drawings.

DoorWin includes visual drawing tools for:

• Fixed windows
• Sliding windows
• Casement windows
• Tilt & Turn windows
• Single and double doors
• Custom configurations

This helps businesses present projects more clearly to customers.

Material Estimation

In Excel, material calculations depend on formulas created and maintained by the user. Incorrect formulas or accidental edits can affect results.

DoorWin automatically calculates material quantities based on the project design, helping reduce repetitive calculations and improving consistency.

---

Pricing and Quotations

Excel can produce quotations, but templates, formulas and formatting usually need to be created and maintained manually.

DoorWin generates quotations directly from project information, reducing the amount of manual preparation required.

---

Project Management

Managing multiple customers and quotations with spreadsheets may become more difficult as the number of projects grows.

DoorWin keeps customer records, quotations and projects together, making it easier to organize ongoing work.

---

Mobility

DoorWin is designed for use on mobile devices, allowing professionals to work during customer visits, site measurements and installations.

Excel is available on mobile devices as well, but spreadsheet editing is generally less convenient for field workflows.

When Excel May Be Enough

Excel can still be a practical choice if you:

• Prepare only a few quotations each month.
• Already have well-tested spreadsheets.
• Do not need visual window drawings.
• Prefer a general spreadsheet tool.

DoorWin may be a better fit if you:

• Prepare quotations regularly.
• Design windows and doors.
• Want automatic material calculations.
• Need faster quotation creation.
• Manage multiple customer projects.
• Work on-site with mobile devices.
• Prefer software built specifically for the window and door industry.
