Boat Storage and Winterization Billing Software (2026)
Storage is recurring per-boat rent, winterization is a seasonal service package, and most operators sell both to the same customer. ShowTheReceipts ($15/mo) bills the monthly storage rate automatically against a card on file and invoices the winterization package as its own job, so one customer's two revenue streams stay straight.
How we picked
Entry-plan prices as published in 2026, checked against each vendor's own pricing page or a recent third-party summary. Judged on the small yard operator's real workflow — recurring per-unit billing, seasonal service packages, and card-on-file collection — not on marina slip inventory or dockage management.

| Kickserv Flex | $19/mo | Budget scheduling and invoicing |

Two businesses, one customer
Storage is rent. Winterization is a service job. Mixing them into one number costs you the service revenue, because rent is the thing customers shop on price.
Bill them separately and both get valued separately.
1. ShowTheReceipts — $15/mo
Recurring monthly storage against a card on file, plus a winterization package invoiced as its own job on the same customer record.
2. Joist — Free / $8/mo
One-off invoices; nothing recurring.
3. Invoice2go — $9.99/mo+
Simple mobile invoicing with basic templates.
4. Kickserv Flex — $19/mo
Budget scheduling and invoicing.
5. DockMaster — quote-based
Marina-scale slip and service management; heavy for a yard with a fence and a forklift.
The fall package that sells itself
- Engine winterization (per engine)
- Water and head systems
- Battery pull and tender storage
- Shrink wrap, priced per foot
- Spring commissioning, prepaid at a discount
The last line is the one worth adding — prepaid spring work locks the customer in before anyone else quotes them.
Frequently asked questions
How should storage be billed — monthly or for the season?
Monthly recurring against a card on file is the cleanest, because it spreads the customer's cost and gives you predictable income. Season-in-advance works too, and both are just different schedules on the same customer record.
Should winterization be bundled into the storage price?
Price it as its own package so the customer can see what the service includes — engine, water systems, shrink wrap, battery. Bundling it into rent makes it look free and makes it the first thing they try to negotiate away.
How do I stop losing track of what's in the yard?
Every boat is a customer record with its own recurring invoice, so anything being billed is by definition still on your lot. The billing list becomes the inventory list.
Is recurring billing included at $15/month?
The entry plan covers quoting, invoicing, card payment, and tax-ready books. Recurring invoices and automated reminders — what a storage business runs on — are Pro-plan features at $39/month.
