Built for 40–150 slip marinas

Run your marina without paying for five modules you don't need.

Slip assignments, contracts, waitlists, invoicing, and reporting — one flat-priced tool for independently-owned marinas. No fuel dock module, no POS add-on, no per-feature pricing stack.

No setup fee. No annual contract. Map your slips and take your first payment the same day.

The problem

Incumbents sell you a bundle. You need three things.

Dockwa and DockMaster price slip booking, contracts, billing, POS, and fuel management as separate modules starting at $169–$249/month each. A marina that just wants slip booking, contracts, and payments ends up paying $500–700+/month for capability it's forced to buy in bundles.

The module stack
  • Slip booking module — separate subscription
  • Contracts & billing — another module, another fee
  • Fuel dock, POS, work orders — features you'll never use, priced in anyway
  • $500–700+/month once you add what you actually need
  • Sales calls and contracts to get started
Slipwise
  • Slip map, contracts, waitlist, invoicing, and payments — one product
  • One flat monthly fee by slip count, no module stacking
  • Nothing to configure around features you don't need
  • $79–149/month depending on slip count
  • No setup fee, no annual contract requirement
What's included

Everything the office actually touches every day

No fuel dock, no ship's store inventory, no multi-location tooling. Just the operational core.

02 · Contracts & waitlist

Fill an open slip in under 5 minutes

Create a contract — renter, vessel, rate, term — and the slip flips to Occupied while the first invoice generates automatically. When a slip opens up, your waitlist queue tells you exactly who's next, in order.

03 · Invoicing & reporting

Know what you made and who still owes you

Auto-generated invoices from every contract, manual charges for one-off fees, and payment recording that updates balances in real time. Pull revenue, occupancy, and outstanding-balance reports as CSV without contacting support.
