Frequently asked questions

Should plumbers charge a trip fee on the invoice?

Many plumbers do, especially for diagnostic visits. List it as its own line and state whether it is waived when the customer approves the repair.

How do I price a plumbing bid for new construction?

New construction bids are usually split into rough-in, top-out and finish (trim) phases, with fixtures either supplied by the builder or priced as allowances.

Is an estimate legally binding?

Generally, no. An estimate is an approximation. It becomes part of a binding agreement when the customer signs and accepts it, and many contractors attach their contract terms at that point. Rules vary by state and country.

How long should an estimate be valid?

Thirty days is common. Use a shorter window when material prices are volatile.

Can I turn an estimate into an invoice?

Yes. With a free HardHat Quote account you can save the estimate, and on Pro you can convert an approved estimate into an invoice in one click.
