Which document do you actually need?

An estimate sets expectations before work starts — a price the client can accept, with an expiry date so it doesn't linger past the point your costs have changed. An invoice is the bill for work already done or in progress, with a due date and, ideally, real tax applied. A receipt confirms a payment was received — proof for the client's own records, not a request for money.

Use whichever matches where you are in the job: estimate before the work, invoice during or after it, receipt once it's paid. Sending the wrong one is a common source of confused clients and late payments — an "invoice" with no due date read as an estimate, or a receipt that looks like a fresh bill.

Questions

What's the difference between an estimate and a quote?
Nothing meaningful for how you'd use one — the estimate generator here covers what's often called a quote or a proposal too: a price you send before work starts, with an expiry date so it can't be accepted six months later at last year's costs.
Can I turn an estimate into an invoice later?
Not in the free tools — each generator here makes a stand-alone document with no memory of the others. In Ochre, approving a quotation lets you convert it into a draft invoice at the agreed prices; the quotation stays as the record of what was quoted.
Is a receipt the same as an invoice marked paid?
Not quite. An invoice marked paid is still a request for money that happens to be settled; a receipt is written the other way round, as confirmation a payment already happened. Some clients specifically need one or the other for their own bookkeeping.

What this page cannot do

Three documents that do not know about each other.

An estimate here cannot become an invoice, and an invoice cannot become a receipt — every generator starts from an empty page. In Ochre they are one thread: an approved quotation converts into a draft invoice at the prices you agreed, and recording a payment against that invoice is what produces the receipt, numbered from the invoice it settles.
