01
Create a Project
Click "New Project" in the left panel and name it after your client or property. Each project saves automatically and holds every space for that job.
02
Fill In Your Project Details
Add your client name, project address, currency, tax rate, and your logistics percentages (shipping/freight, warehouse/storage, delivery and install) at the top of each view. Logistics lines are calculated as a percentage of the furnishings subtotal. If you are working with international clients, select their local currency and the guide pricing will convert automatically — verify local market rates before presenting to clients.
03
Work Through Each Space
Navigate spaces using the left sidebar. Every project starts with all 16 standard rooms pre-loaded with line items. The three dots next to each space show your completion progress as you fill it in. For each item, use the Guide Reference dropdown to select the product type from your Investment Guide. Choose Low, Mid, or High to auto-fill the unit investment based on that tier — converted to your project currency automatically. You can always edit the amount manually. Enter the quantity and the line total calculates itself. Example: 6 dining chairs at Mid = auto-filled and ready to confirm or adjust.
04
Add Custom Spaces as Needed
Every home is different. Use the "Add Space" button to include any room or area not covered by the 16 standard spaces. Start from a template or build from scratch.
05
Review the Project Summary
Click "Project Summary" in the sidebar to see the full rollup — every space total, tax, logistics costs, and your grand total investment range for the project.
06
Save and Pick Up Where You Left Off
Your work saves automatically in your browser. To move a project between devices, click "Save Project" in the top bar to download a .json file, then use "Load Project" on any device to bring it back in. One file per project, easy to store and share with yourself.
07
Export a Branded PDF for Your Client
When you're ready, use "Export Estimate PDF" for a detailed breakdown you can review internally, or "Generate Approval Form" to produce a clean client-facing document listing each room total with a signature line per space and a full project approval signature block at the bottom. Both PDFs carry your branding only.
License & Access Notice

This tool is licensed for single-user access only. Your purchase grants access to one designer or firm. Sharing your password, forwarding access, or distributing this tool in any form is a violation of your license agreement.

All access is monitored. Unauthorized sharing is tracked and will result in immediate license termination without refund. If you need access for additional team members, contact info@mcclainmethod.com for multi-seat options.

How Your Data is Stored

Your projects save automatically in your browser on this device. That data is tied to your password — if someone else opens this tool with a different password on the same computer, they will see nothing. Your work is invisible to them.

Your data does not sync to the cloud or any server. It lives in this browser only. Do not clear your browser data unless you have already downloaded your projects using the "Save Project" button. Clearing browser data will permanently delete everything stored here — and there is no way to recover it. The PDF export is for your client, not a backup of your work.

If you switch devices or need to move your work, use "Save Project" to download a .json file and "Load Project" to bring it in on the other device. Get in that habit at the end of every working session.

Clearing browser data will also log you out of this device. Your password cannot be reset or recovered — it was set at the time of purchase and is fixed. Keep it somewhere safe because it is the only way back in.

The cloud version of this tool is coming. When it launches, you will be able to migrate your saved files straight in.
