Boat repair businesses include marine mechanics, fiberglass and gelcoat specialists, marine electricians, rigging and canvas shops, and mobile techs who work at the slip, the yard, or the owner's driveway. They bill for diagnostic time, repair labor, parts and materials, haul-outs and storage, and shop supplies. Jobs range from a one-hour impeller swap to a multi-month repower or hull restoration.

Most boat repair is billed hourly for labor, plus parts at a markup, plus a small shop supplies or environmental fee. Shop rates are usually lower than mobile rates because mobile work includes travel and a stocked truck. Many shops set a one-hour minimum for diagnostics and a trip charge for dockside calls. Routine jobs such as oil changes, winterization, and commissioning are often sold as flat-fee packages priced by engine type or boat length. Fiberglass and paint work is sometimes quoted per foot of boat length or per square foot of repair. Larger projects such as repowers, engine rebuilds, and refits are typically billed time and materials against a written estimate, with progress billing and a deposit to cover parts. Parts are commonly marked up 15-40%, with special-order and high-cost parts at the lower end. Yard charges like haul-out, launch, blocking, and storage are usually billed per foot of boat length and passed through from the marina or itemized separately.

Notes: Payment due within 15 days of invoice date. Parts carry the manufacturer warranty; labor is warrantied for 90 days. A 1.5% monthly fee applies to balances past due. Vessel will not be released from the yard until balances on completed work are paid.
Identifies exactly which boat was worked on, which matters for warranty claims, insurance, and disputes over multiple vessels owned by the same client.
Records the condition of the equipment when you serviced it and supports warranty claims and maintenance history.
Owners and insurers want to see what was replaced, and it makes warranty returns easier.
Separating diagnostic, repair, and travel time reduces pushback on total hours.
These are often pass-through costs from a marina or yard and should not be hidden in labor or markup.
Covers oil, fuel, bottom paint waste, and solvents. A clear line item avoids looking like padding.
Ties the bill to what the owner approved, including any approved change orders for added work.
For small repairs, payment is usually due at pickup or on completion, often by card, check, or ACH. Larger jobs typically require a deposit of 25-50% or the full cost of special-order parts before ordering, then progress payments at set milestones and the balance before the boat is launched or leaves the yard. Net 15 is common for commercial clients and marinas. Late fees of 1-2% per month are typical if stated in writing in advance. In many states, a repair shop can file a mechanic's or possessory lien on a vessel for unpaid work, but the rules vary, so check your state's requirements and keep your signed work authorization on file.
Include the approved scope, hourly rate, estimate limit, storage terms, and a statement that you may hold the vessel until paid. This supports a lien claim if you need one and prevents arguments about what was approved.
Marine parts are often special order and non-returnable. Collect payment for them upfront or require a deposit so you are not carrying the cost of an engine or electronics package if the owner walks away.
Tracing a fault is real work. State the diagnostic minimum on your estimate or authorization and invoice it whether or not the repair goes ahead.
Soft decking, corroded wiring, and hidden hull damage show up once you open things up. Photograph them, send a written change order, and wait for approval before doing the extra work.
If an owner delays approval or payment, boats take up yard space. Put a storage rate, such as a per-foot daily or monthly charge, in your authorization and start billing after a stated grace period.
Yes, most mobile techs do. A flat trip charge or a travel-time rate covers drive time and truck costs. Some waive it for customers on a service contract or when multiple boats at the same marina are serviced in one visit.
Typical markups run 15-40% over your cost. Smaller, common parts such as filters and impellers carry higher markups, while expensive items like engines and electronics are marked up less. Apply the same policy to all customers and show it consistently.
In many states, a repair shop has a possessory lien on a vessel in its custody for unpaid repairs, but the rules and notice requirements vary. Keep a signed authorization stating your terms and check your state's law or talk to a maritime attorney before selling or retaining a boat.
It depends on the state. Many states tax parts but not labor, some tax both, and some have exemptions for commercial vessels or work on boats used in certain ways. Check with your state's department of revenue and show tax separately on the invoice.
List the work with the usual labor and parts detail, then show the warranty credit or manufacturer-billed amount as a separate line so the customer sees a zero or reduced balance. Include the warranty claim number for the manufacturer.
Send a Boat Repair estimate for approval, then turn it into an invoice when the work is done.
