Estimate Maker

Send an estimate, then turn it into an invoice

Agree the price before you start, and the invoice never comes as a surprise. Invoice Maker drafts the estimate, sends it as a clean PDF, and converts it into a full invoice the moment the job is approved.

In short

An estimate maker lets you send a proposed price before the work begins. In Invoice Maker you draft the estimate with the same client, products, tax and layout as your invoices, send it as a PDF, and then convert it into an invoice in one tap once the client approves — so nothing is retyped and the totals stay consistent.

Quote first

Fewer surprises, faster payments

A quote sets expectations. When a client has already seen the number and agreed to it, the invoice is a formality instead of a negotiation.

  • Draft an estimate with the same items you will bill.
  • Send it as a PDF by Mail, Messages, WhatsApp or Files.
  • Convert the approved estimate into an invoice in a tap.
  • Keep estimates and invoices separate in your records.
Estimate vs invoice

One leads to the other

An estimate is a proposal you can still change. An invoice is a request for the money that is now owed. Because Invoice Maker treats them as two stages of the same document, the client, the line items and the tax move across with one tap — and your invoice numbers stay clean and sequential.

Tip. Number estimates and invoices in separate sequences (for example EST-001 and INV-001) so it is always obvious which document you are looking at.

Questions

Frequently asked questions

What is an estimate maker?
An estimate maker (sometimes called a quote maker) lets you send a proposed price for a job before the work starts. Invoice Maker lets you draft that estimate, send it as a PDF, and then convert it into a full invoice once the client approves it.
What is the difference between an estimate and an invoice?
An estimate is a proposed price sent before the work — it can change. An invoice is a request for payment sent after the work is done. Invoice Maker keeps the two linked so you do not re-type anything when it is time to bill.
Can I turn an estimate into an invoice?
Yes. Once a client approves the estimate, convert it into an invoice in a tap. The client, line items and totals carry over, and the document gets a proper invoice number.
Should a quote include tax?
It can. Including tax on a quote gives the client a realistic total, and Invoice Maker carries the same tax setting through when you convert the quote into an invoice.
Is a quote legally binding?
In most places a signed or accepted quote forms an agreement about price and scope, but the rules vary. Invoice Maker is a tool for producing the document, not legal advice.
