When does a spreadsheet work well?
A spreadsheet works well when you want a calculation model you know, your own estimating formulas or offline preparation. You control its columns and formulas. You also need your own way to protect the formulas, track file versions and put together the proposal the homeowner sees.
What does PoolQuote add?
PoolQuote ties together your catalogue items, concept images, a check that each quote line is complete, and a published link for the homeowner. It records the homeowner's responses and keeps revisions explicit. That can cut down manual assembly, but reviewing the catalogue and pricing each project stay your work.

How do the two compare?
A spreadsheet can be adapted almost any way, while PoolQuote gives you a set workflow. You may already pay for spreadsheet software; PoolQuote has a subscription and a credit model. Neither choice guarantees a saving or a higher win rate.
- Calculations: your own spreadsheet formulas, or structured quote lines.
- Visuals: images assembled from elsewhere, or concept images and proposals built in.
- Sharing: sending files, or publishing one link you control.
- Changes: managing file versions, or explicit published revisions.
- Follow-up: tracking by hand or in another tool, or response signals in the product.
How do you test both on one job?
Take a finished job you have permission to use and build a demo proposal both ways. Compare the steps, how clear the result is, the corrections it needed and how the homeowner would see an update. Go by what you observe rather than an unsupported time-saving claim from any vendor.
