What's the difference?
Estimate, quote, and invoice are related but used at different moments.
Estimate
A rough price when the final cost may still change. Good for early conversations or jobs where the scope is flexible.
Create estimate →Quote
A clear price for the customer to approve. Good when you know the scope and want a yes before you start.
Create quote →Invoice
A request for payment. Use it when the work is done or the customer needs to pay.
Create invoice →EstimateQuoteInvoice
You can start wherever you are.
