Custom marina management software runs $60,000 to $400,000 in our delivery experience, and the decision that moves the number most is whether the fuel dock is in scope. Live tank monitoring, pump controller integration and the reporting your state environmental agency expects depend entirely on which hardware sits at your fuel shack, and the range between a modern controller with a documented interface and a twenty year old console is several weeks of work. Leave fuel out of release one and a three property build lands near $120,000. Put it in and the same scope moves toward $170,000 before anything else changes.
The bands a marina build falls into
A focused first release runs $60,000 to $130,000 and ships in 12 to 16 weeks. That buys the vessel and customer data model, a physical slip inventory with fit based availability rather than a calendar, contracts and transient booking, payments with cards on file, the dockmaster's daily view and a clean accounting export. It replaces your booking tool and your slip spreadsheet. It does not yet replace your service yard.
A full platform runs $150,000 to $400,000 phased over 6 to 12 months. That adds service work orders with mobile time capture, parts and inventory, the fuel dock, yard mapping and haul out planning, a customer portal, multi property rollups and the automated pieces that actually save labour: after hours booking, document extraction from haul out forms and insurance certificates, and renewal sequences.
Slip count is a weak predictor of cost. A single 400 slip marina with seasonal contracts and no yard costs less to serve than a three property operation with 300 slips, a service yard and 250 boats stored on the hard each winter. What you pay for is the number of distinct businesses running under one roof.
What drives a marina build up
Six things account for most of the variance between a $70,000 quote and a $350,000 one.
- Fuel. Covered above. Tank monitoring, pump controller integration and environmental reporting are entirely hardware dependent, and the answer to whether it is cheap or expensive is written on the side of your existing console.
- Yard mapping and haul out. Placing 300 to 600 hulls into a fixed area with stand requirements, fire lanes, lift path clearances and an access order constraint driven by requested launch dates is a genuine optimisation problem against a real survey of your property. It is not a form and it is not cheap.
- Property count. Rollups, per property rate cards, and an accounting export coded by property are each modest on their own and add up. The second property is much cheaper than the first. The fifth is not free.
- Service yard depth. Work orders with mobile clock in, parts pulling from the same stock as the ship store, and invoicing on completion is a subsystem, not a feature.
- Tax treatment. Where dockage, service labour and fuel are taxed differently, and the rules differ by state, that logic is real work and it is not portable between jurisdictions.
- Migration. Ten years of contracts, vessel records and service history spread across a booking platform, an old database and forty spreadsheets is typically two to four weeks of data work on its own.
What keeps the number down
Build the slip and booking core first and let it stop the double booking problem before anything else is attempted. That is the release that pays for itself in refunds you no longer issue and evenings your dockmaster gets back.
Keep your accounting package. There is no version of this project where rebuilding a general ledger improves your position, and a clean export coded by property and revenue class delivers everything you actually need. Keep your card processor and stay out of scope for card data entirely by using tokenisation, which is both the cheaper and the safer design.
Defer fuel. Defer yard mapping to the season after go live, so you have a full winter of real data about how your yard actually fills before anyone writes a placement engine. And be honest about migration: bring across active contracts, current vessels and open balances, and archive the rest as read only. Nobody has ever needed a 2014 work order at speed.
A worked example that adds up
Three properties, roughly 600 slips combined, a service yard, winter storage for about 250 boats, currently on a booking platform plus spreadsheets plus a desktop accounting package. Release one is the slip and booking core. No fuel, no yard mapping, no service work orders yet.
- Discovery, dock survey and slip constraint capture across three properties: $10,000
- Vessel and customer data model with one account across all properties and revenue streams: $16,000
- Physical slip inventory: length overall, usable finger length, beam clearance to the neighbour, controlling depth with a tide offset, pedestal amperage and count, and coordinates: $20,000
- Fit based availability query returning slips that physically work, ranked by revenue yield: $14,000
- Contracts, seasonal and transient booking, per property rate cards with holiday minimums: $22,000
- Payments with cards on file through a tokenising processor, keeping card data off your servers: $12,000
- Dockmaster daily view with arrivals, departures and exception board: $9,000
- Accounting export coded by property and revenue class: $9,000
- Migration of active contracts, vessels and open balances: $10,000
That totals $122,000, inside the first band and where a three property slip core usually lands. Cut the yield ranking and take a simpler migration, importing only current season contracts, and the same scope comes in at $102,000. Add service work orders with mobile time capture and parts, which is the phase most operators fund next, and expect roughly $45,000 more, taking the programme to about $167,000 and into the second band.
How the spend phases
Discovery takes eight to ten percent and includes a physical walk of the docks. That sounds like a soft cost and it is not. The constraints that make fit based availability work, the finger side, the neighbour clearance, the pedestal that is 30 amp on the old dock, are not written down anywhere except in your dockmaster's head, and getting them out of it is the most valuable week of the project.
Build runs in six to eight two week increments invoiced on delivery. Aim to have the dockmaster running his day in the system by week ten, in parallel with the old tool, so the first real Friday in season is a rehearsal rather than a launch.
Hold twelve to fifteen percent for stabilisation. Marinas have a brutal seasonality, and the honest advice is to go live in the shoulder season rather than in June. A system that launches in April has two quiet months to be fixed before it is load tested by a holiday weekend.
Phase two, service and fuel and yard, funds in $40,000 to $90,000 releases. Fund each one after the previous has run through a season.
The ongoing costs nobody quotes
Hosting for a three property operation is modest, typically $300 to $900 a month. Card processing you already pay. Text messaging for arrival instructions and renewal reminders is consumption priced and small, but it is not zero and it scales with your transient volume.
The costs people miss are physical. Dock wifi that actually reaches the far end of E-dock is a capital item, and a dockmaster with a tablet that loses signal at the point of sale (POS) is a system nobody uses. Rugged devices for the service yard live in a hostile environment and get replaced. Both belong in the budget for the same reason the software does.
Document extraction, if you add it, is priced per page and lands in the low hundreds of dollars per season at 400 haul out forms, insurance certificates and surveys, which is a rounding error against the office hours it removes.
Support and maintenance runs fifteen to twenty percent of build cost annually, so roughly $22,000 on a $122,000 build. Weight it toward the season. A maintenance arrangement that gives you a slow response in July is worth much less than the same arrangement in January.
Comparing a build against your current renewal
Your booking platform subscription is only part of the number. Add the point of sale at the fuel shack, the accounting package, the service side tooling, and any integration service you pay to move data between them. Then add the reconciliation labour, which at three properties with four revenue streams is a real fraction of an office manager's month, and which nobody puts on a slide because it is spread across a salary that also does other things.
Then add the leaks. Technician hours that never reach an invoice because they were written on paper a week earlier. Transient nights lost to a phone that rang at 9pm and was not answered. Contract renewals that quietly lapsed because nobody chased them. Storage spots sold at a guess in October because the yard count was an estimate.
Over five years a $122,000 build with $22,000 annual support totals $232,000. Whether that beats your current arrangement depends on your own numbers. What tips it for most multi property operators is not the subscription line at all. It is that the reconciliation labour and the unbilled service hours together already cost more than the build, and neither appears on any invoice.
When buying beats building
If you are a single marina under roughly 200 slips, your revenue is mostly seasonal contracts and transients, your service work is subcontracted and you store fewer than a hundred boats, buy. Molo or Marina Master will serve you properly, and a build is a poor use of $100,000. Spend the difference on dock infrastructure, which will do more for your business than any software will. That is the right answer for most of this market and we say it on sales calls regularly.
Dockwa is worth keeping in the mix specifically for transient demand, because the distribution matters as much as the software. A marina that builds a booking system and loses a demand channel has made itself worse off.
The build case appears when the signals cluster. You operate more than one property and cannot see combined occupancy without a spreadsheet. Your service yard bills over roughly $750,000 a year and technician hours reach the invoice by hand. You store more than 200 boats and the yard map is one person's file. Your annual software and integration spend is already past $30,000 and you still reconcile manually. And the one that matters most: your dockmaster's real slip logic, the fit rules, the tide, the neighbour clearances, exists only in his head, and you have realised that when he retires you lose it. That is not a software problem on paper, and it is the most expensive item on the list.
When the shortlist is down to two and you need a tiebreaker, Digital Heroes has delivered more than 2,000 projects with a named team you can speak to before you sign, rather than a bench you meet in month two. Nothing about that commits you to the build.

Frequently asked questions
What is the total cost of custom marina management software?
A first release covering the vessel and customer model, physical slip inventory with fit based availability, contracts and transient booking, payments and an accounting export runs $60,000 to $130,000 over 12 to 16 weeks in Digital Heroes delivery experience. A full platform adding service work orders, fuel, yard mapping, a customer portal and multi property rollups runs $150,000 to $400,000 across 6 to 12 months.
Property count, fuel hardware and yard mapping drive the number. Slip count barely does.
What does it cost to run each year?
Fifteen to twenty percent of build cost annually for maintenance, so roughly $22,000 on a $122,000 build, plus $300 to $900 a month hosting for a three property operation. Weight the support arrangement toward the season, because a slow response in July is worth far less than the same response in January.
Budget separately for dock wifi that actually reaches the end of the far dock and for rugged devices in the service yard. Both are physical costs that software budgets routinely omit, and a tablet that loses signal at the point of sale is a system nobody uses.
How long before the dockmaster is using it?
Twelve to 16 weeks to a first release covering slip inventory, contracts, transient booking and billing, with the dockmaster in it from day one of go live. Service work orders, fuel and yard mapping are usually phase two over the following four to eight months.
Go live in the shoulder season rather than in June. A system that launches in April gets two quiet months to be fixed before a holiday weekend load tests it.
Is Molo or Marina Master cheaper than building?
For a single marina under about 200 slips with mostly seasonal contracts and no service yard, comfortably yes, and we would tell you to buy. Both handle reservations and payments properly and the subscription is a fraction of a build.
The comparison changes at multiple properties with a service yard, fuel and winter storage, because those tools were never designed to hold a hull sitting on stands at a coordinate in your yard or a technician's clocked hours. Stitching them together costs more in reconciliation labour than the difference in software, and that labour is already in your payroll.
How much does adding the fuel dock cost?
Typically $35,000 to $70,000, and the range is set by your hardware rather than by your requirements. A modern controller with documented interfaces sits at the bottom. An older console that offers a serial stream and nothing else sits at the top, and state environmental reporting adds work on either.
Most operators leave fuel out of release one for exactly this reason. Getting your controller model and its interface documentation before scoping turns a wide estimate into a narrow one, and it is an afternoon of your time.
What does yard mapping and haul out planning cost?
Expect $30,000 to $60,000. It is a bin packing problem with an access order constraint rather than a booking problem, so it needs a real survey of your property with rows, stand inventory, fire lanes and lift path clearances, and placement sorted by requested launch date.
Defer it to the season after go live if you can. A winter of real data about how your yard actually fills makes the placement engine substantially better and cheaper to build, because you are encoding observed behaviour rather than guessing at rules.
How much does migrating off our current system cost?
Budget $8,000 to $25,000 and two to four weeks, and treat it as a real line item rather than a footnote. Exporting contracts, customers and vessels is straightforward. Reconciling duplicate vessel records, matching owners who appear three different ways across systems and deciding what service history carries forward is judgement work.
Bring across active contracts, current vessels and open balances. Archive everything else as read only, because nobody has ever needed a decade old work order at speed.
Does a second or third property double the cost?
No. The second property is comparatively cheap because the model, the booking flow and the payment path already exist. What each additional property adds is its own rate card, its own dock survey and its own line in the rollups and the accounting export, which in our experience runs six to twelve thousand dollars per site.
The exception is a property with materially different operations, such as one with fuel or a haul out yard when the others have neither. That is closer to a new phase than a new site.
What is the cheapest version worth building?
Around $60,000 to $80,000 for the vessel and customer model, physical slip inventory with fit based availability, contracts and transient booking, payments with cards on file and a dockmaster day view. One property, simple migration, no yield ranking, no portal.
That version gets your dockmaster's slip logic out of his head and into a database, which is the single most valuable thing this category of software does. Everything else can wait until it has run through a season.
How many people does it take to build a booking platform?
A typical booking system team is four to five people: a project manager, a designer, one backend developer, one frontend developer, and part-time QA. On Digital Heroes projects that team ships an MVP in 6 to 10 weeks; a solo developer can build the same system but usually needs about three times the calendar time. You only need a larger team if native iOS and Android apps ship at the same time as the web platform.
How long does it take to build custom booking software?
Plan on 6 to 10 weeks for a working MVP and 3 to 5 months for a full platform with memberships, reporting, and integrations. Across Digital Heroes booking projects, the calendar engine takes about a third of the timeline because recurring availability, time zones, and double-booking prevention need heavy testing. Migrating data from your old tool usually adds 1 to 2 weeks at the end.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
How long does it take to build a custom web or mobile app from scratch?
Plan on 8 to 16 weeks for a focused first version and 4 to 9 months for a larger platform, which is the typical spread across Digital Heroes builds. The first 2 to 3 weeks go to discovery and design before any production code ships. The two things that stretch timelines most are integrations with legacy systems and slow feedback from your side, not developer speed.
How quickly does a custom booking system pay for itself?
Payback comes from three lines: cancelled subscriptions, which run $100 to $600 a month for tools like Mindbody, recovered no-show revenue from deposits and reminders, and admin hours saved on manual scheduling. For businesses handling 300+ bookings a month, Digital Heroes typically sees a $20,000 to $30,000 build recover its cost within 18 to 30 months. Under about 100 bookings a month the math rarely works, and an off-the-shelf tool remains the right call.
How many people should be working on my software project?
Three to five for a typical focused build: a project lead, one or two engineers, a designer, and part-time QA, which is the standard shape across 2,000+ Digital Heroes projects. Larger platforms justify 6 to 10, but a ten-person team on a small first version usually signals bill padding rather than horsepower. What predicts success is whether a senior engineer is writing your code daily, not the headcount on the proposal.
Who can build a custom booking & scheduling software system?
Digital Heroes builds custom booking & scheduling software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other booking & scheduling software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?

Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
