What is an estimate, and how is it different from a quote?
An estimate is a good-faith approximation of what a job will cost, given before you know every detail, common when a final price depends on what you find once work starts (a renovation, a repair, a consulting engagement scoped as you go). A quote, by contrast, is a fixed price you're committing to. Estimates set expectations; quotes lock in a number.

Who needs a Estimate?
An estimate protects both sides of a job: the client isn't blindsided by the final bill, and you have a documented figure to point back to if the scope grows.
The real cost often depends on what's behind the wall. An estimate sets a realistic range before you commit to a fixed number.
A written estimate after a discovery call gives the client something concrete to approve before a contract is drafted.
A professional, itemized estimate signals you run a real business, which matters more with a client who hasn't worked with you before.
Estimate vs other billing documents
Where an estimate fits alongside the rest of your billing documents.
| Document | Purpose | Who sees it | Send it when |
|---|---|---|---|
| Estimate | Give a good-faith figure that may still shift | Client wants a ballpark before you're on site | When scope isn't fully known yet |
| Quote | Lock in a fixed price before work starts | Client deciding whether to hire you | When price certainty matters |
| Invoice | Request payment for work delivered | Client who owes you money | Every completed job |
| Receipt | Confirm a payment was received | Client who already paid | After every payment |
Key takeaway: Use an estimate when the final cost is genuinely uncertain; use a quote when you can commit to a number today.

Frequently asked questions
Questions about Estimate before you get started?
What is the difference between an estimate and a quote?
An estimate is a rough, good-faith figure for a job where the exact scope may still shift, useful when you can't know the final cost until you're on site. A quote is a fixed, binding price the client can accept as-is. BillyPaid supports both as separate document types.
Can a client approve an estimate online?
Yes. Estimates include a shareable link where the client can review the line items and accept or decline with one click, no printing or emailing a signed copy back and forth.
Does an accepted estimate turn into an invoice?
Yes. Once a client accepts, you can convert the estimate into an invoice in one click. Every line item carries over, so you're not re-typing the same job details twice.
Can I revise an estimate after sending it?
Yes. You can edit and resend an estimate at any point before the client accepts it. BillyPaid keeps a version history so you can see what changed and when.
