Question 1

Is this estimate maker really free?

Accepted Answer

Yes. FluxInvoice's estimate maker is completely free to use with no watermarks, no usage limits, and no sign-up required. Create and download as many professional estimates as you need.

Question 2

What is the difference between an estimate and an invoice?

Accepted Answer

An estimate (also called a quote) is sent to a potential client before the work begins. It outlines the expected cost of a project. An invoice is sent after the work is completed to formally request payment. Estimates are proposals; invoices are payment demands.

Question 3

Can I add a client approval signature section?

Accepted Answer

Yes. FluxInvoice's estimate maker includes an optional signature/approval section that you can add to your estimate PDF. This gives clients a clear place to sign off and approve the quoted work before you begin.

Question 4

What is a 'Valid Until' date on an estimate?

Accepted Answer

A 'Valid Until' date specifies how long your quoted price is guaranteed. Material costs, labor rates, and availability can change, so it's good practice to include an expiry date on your estimates — typically 30 days from the issue date. This protects you from being locked into a price if a client takes too long to respond.

Question 5

Can I customize my estimate with my logo?

Accepted Answer

Yes. You can upload your business or personal logo directly in the estimate editor and choose how it is aligned on the document. A branded estimate looks far more professional than a plain-text price list and significantly increases client trust.

Question 6

Does FluxInvoice store my estimate data?

Accepted Answer

No. All estimate data is processed locally within your own browser and is never sent to our servers. Your client names, project descriptions, and pricing remain completely private. The optional Auto-Save feature stores drafts only on your own device.

Question 7

Can I convert my estimate into an invoice?

Accepted Answer

Yes. Once a client approves your estimate, you can easily recreate it as an invoice using the FluxInvoice free invoice generator. Simply copy the line items and client details across. We are also building a one-click estimate-to-invoice conversion feature.

Question 8

Is this estimate maker suitable for contractors?

Accepted Answer

Absolutely. FluxInvoice's estimate maker is designed with contractors, tradespeople, and service providers in mind. You can add detailed line items for labor and materials, specify a valid-until date, and produce a polished PDF estimate that wins client confidence.
