Marina billing software with autopay and late fees

At most marinas the money side lives in three places at once: invoices in QuickBooks or Word, a card terminal at the counter, and a spreadsheet of who still owes for the season. The deposit comes in spring, the balance in January, and somewhere in between the office spends its mornings matching checks to invoices and calling the people who forgot.

SlipRight runs marina billing from the contract out: the season's slip with its deposit and balance, monthly slips, winter storage, transient stays, and work on the boat. The invoices come from the agreement the boat owner signed, boat owners pay them from their phone or any browser, autopay collects on the due date, and the office sees what's due, paid, and late on one page, from the computer, a tablet, or a phone.

Invoices that follow the contract

Each season's offer carries a payment schedule: a named split with a share and a due date, or a number of days after acceptance, such as half on acceptance and half in January. When the boat owner accepts, SlipRight drafts every invoice in that schedule. The office sends them when it likes, one agreement at a time or all at once, and each one tells the owner by email, push, or text.

Invoices for everything else work the same way. A finished work request becomes an invoice from its parts and labor, a transient stay is billed like a seasonal slip, and the office can write one by hand, right from the Dashboard.

One boat's season, invoice by invoice

Here's how a renewal bills, with made-up numbers to show the shape. A 30-foot boat's summer slip is $3,600 for the season, plus a $150 pump-out package from your catalog, and the template splits it half on acceptance and half on April 1.

1. In December the office sends next season's offers from the template. The owner signs on their phone, and SlipRight drafts two invoices of $1,875 each, one due on acceptance and one due April 1.
2. The office sends them. The owner pays the first by card in My slip, saves the card, and turns on autopay.
3. On April 1 autopay charges the balance and the owner gets a receipt. If the card is declined, SlipRight tries again three days later and seven days later.
4. If it still isn't paid, the invoice turns Overdue, the owner gets one letter, and a late fee follows if you've turned them on.
5. In July the owner asks for a bottom cleaning from the dock. The finished request becomes its own invoice from its parts and labor.

The office sees all of it on one list, and the owner sees the same invoices, payments, and balance on their statement.

Paid by card or ACH, into your own Stripe

Every invoice has a Pay button. Boat owners pay by card or bank account, on their phone or in any browser, and the money lands in your marina's own Stripe account. SlipRight takes nothing from it.

A cut of payments grows with every invoice your boat owners pay. Here's what one comes to in a year:

Collected in a year

$400,000

About 100 slips at $4,000 a slip a year

• SlipRight $0 You pay Stripe's rate and nothing on top.
• Molo $1,400 a year, about $117 a month 0.35% over cost, plus an e-transaction fee at a rate only the signed contract shows (Molo help center, Oct 14, 2026).
• Atlantis $4,000 a year, about $333 a month 1% of each successful payment, on top of Stripe's rate (atlantis-marina.com, Oct 20, 2026).

The slip count assumes about $4,000 a slip a year.

Autopay, so the January balance arrives on its own

A boat owner can keep a card or bank account on file at your marina and turn on autopay, and a payment plan can require it.

• The charge runs on the due date.
• If it fails, SlipRight tries again three days later and seven days later.
• The owner gets a receipt, or a note saying what happened, either way.
• The office can charge a saved method itself when an owner asks.

When an invoice is late

Every six hours SlipRight marks any invoice past its due date Overdue, and mails the boat owner once. Late fees are yours to set in Settings: off, a flat amount, or a percent, after the days of grace you choose. Each late fee is its own small invoice, and the office can waive one with a click.

Refunds, credits, and statements

• Take off an amount on a sent invoice, as its own line, so what was sent stays on the record.
• Refund a paid invoice, all or part, back to the card or bank account it was paid with, or record a refund the office paid by check.
• Give credit, which the customer's next invoice uses.

Every customer has a balance and a statement, on their record in the office and in My slip on their phone.

Reports and the books

Billing → Reports has occupancy by month, who owes by how late (current, 1 to 30 days, 31 to 60, 61 to 90, and over 90), revenue by season, and renewals still outstanding, each a CSV. Export gives you every invoice and every payment and refund by date, and a QuickBooks journal that balances, so your accountant gets the books in the shape they already use.

Want another number on Reports? Tell us which one, and we'll build it with you.

Carrying balances over

Moving from another system mid-year doesn't mean starting the money from zero. The balances import carries over what each customer owes, or has in credit, as of one date: one invoice per customer, marked Sent with nothing mailed. SlipRight never sends an overdue letter for a carried-over balance, since that's the old system's collection, and late fees follow your setting. We'll run it with you. Moving a marina off a spreadsheet shows how it goes.
