Quote vs Estimate vs Invoice: Which Document to Send and When
A quote is an offer, an estimate is a range, an invoice is a request for payment. Mixing them up delays jobs and confuses bookkeeping. Here is when to send each, and how to keep the layouts consistent.
Sales paperwork fails in a boring way. Someone sends an "invoice" before the work is agreed, or a "quote" after the job is done, and the customer does not know whether to pay, negotiate, or ignore it. The words are not interchangeable. The PDFs should not look interchangeable either, even if they share a logo and a line-item table.
This is the sequence most small firms actually use: estimate or quote while the job is still a maybe, invoice when you want money, receipt when money has landed, credit note if you have to unwind part of an invoice. Docuplate ships separate starters for those layouts so the title on the page matches the legal job of the file.
Estimate: a range before the scope is firm
An estimate says "this is roughly what it will cost" when you have not measured every hour or every metre. Trades use them after a site visit. Agencies use them before a discovery week. Put a range or a "subject to site conditions" note in the totals block, and date the document. Do not put "amount due" on it.
The PDF estimate template starter is built for that: job description, line items that can stay approximate, a validity date. When the scope firms up, you copy the lines into a quote rather than editing the estimate until it pretends to be a contract.
Quote: a priced offer the customer can accept
A quote is an offer. It lists what you will do, at what price, until an expiry date. If the customer accepts, that file is the baseline for the invoice. If they do not, you still have a record of what you offered.
Include your ABN or business number, a quote number, line items with quantities, tax if you charge it, and when the price lapses. The PDF quote template layout mirrors the invoice on purpose so acceptance does not mean redrawing the page. What changes is the title, the number prefix (QUO- vs INV-), and the absence of a due date.
Invoice: a request for payment
An invoice is the document you send when the customer owes you money. In Australia, GST-registered businesses generally need a tax invoice for taxable sales of $82.50 including GST or more. Check your own tax office if you are not in Australia; the threshold and required fields differ.
Required in practice, almost everywhere: seller name, buyer name, unique invoice number, date, description of what was supplied, amounts, tax if applicable, amount payable, due date. The PDF invoice template starter has those as blocks. After payment, send a receipt rather than writing "paid" across the invoice in a PDF editor.
Keep the layouts in one system
The usual mess is three Word files that drifted apart in 2023. The quote has an old address. The invoice totals wrap onto a second page. The estimate still has last year's hourly rate in a footer someone forgot.
One template per document type, shared Example data shape (customer, items, totals), and you can generate any of them from a webhook when a deal moves. Quote accepted → invoice. Invoice paid → receipt. Invoice wrong → credit note, not a silent edit of INV-1044.
