A twelve-tab logbook, now one system.
Scuba World Diving ran every dive through one Excel workbook. We fitted Manifest, our dive-centre platform, to the way they work: their logbook, levies, commissions, PADI courses and gear, in their colours, on their own server.

01The challenge
Twelve tabs. Seventy columns. Every figure typed again.
Every dive at Scuba World was recorded in one Excel workbook. Its twelve sheets, some of them seventy columns wide, held the daily logbook, income, expenses, clients who still owed money, supplier invoices, gear stock, diver statistics, annual payments, a month-end close and a balance sheet.

The rules lived in people’s heads, and in formulas.
Money owed was spread across tabs that had to be reconciled by hand, and the manager only saw how a day went once someone had updated the sheet. The business rules were the real complexity:
MSDA levy per diverIn-house guests and non-resort visitorsCommission per instructor and activityPayments in several currenciesVAT on some activities, not others
02Our approach
We fitted the platform to their workbook, not the other way round.
Manifest already handles the day of a dive centre. The work was making it Scuba World’s: their rules, their vocabulary, their data and their way of running the day.
01
The spreadsheet as the spec.
We went through the workbook one sheet at a time. Every column became a field, every formula a business rule and every tab a module, so nothing the team relied on was lost.
02
Their rules, in the database.
26 tables and 4 live reporting views replace the MONTHLY, diver-statistics and daily-summary tabs. 53 row-level security policies give the manager, reception and instructors exactly what each role needs.
03
Their data from day one.
Their dive sites with depths and lagoon category, commission rates and 76 lines of gear from their STOCK GEAR sheet were loaded before the first login.
03One entry, everywhere
A dive is entered once, and appears everywhere it’s needed.
The daily logbook is the source. Income, invoices, balances, diver statistics and the monthly P&L are all calculated from it, never retyped.

The day on the water, at a glance.
The manager’s first screen shows the day itself: revenue with the MSDA levy kept separate, divers by activity, and every boat on a 06:00–21:00 timeline, with a seat that fills for each diver logged.

Planning is for instructors: morning, afternoon and night sessions with site, times, skipper, divers and each instructor’s workload. Finance is for the office: a live P&L for the same day, gear checked out against stock, and one click to turn the day’s rows into income records.

Bookings that flow into the logbook.
A month calendar runs from pending to confirmed to completed. Walk-ins can be booked before a client record exists, and a day’s bookings import straight into that day’s logbook.

Every rupee, split the way they count it.
Income is split by activity and payment method (cash, card or POS, bank transfer) with paid, partial and due states. Invoices are numbered SWD-YYYY-#### and generated as PDFs on the server, for a single client or as a daily batch summary.
Client invoices, numbered
Daily batch summary
The spreadsheet tabs, now calculated.
The monthly P&L, diver statistics, annual expenses by category and month, and a balance overview of what clients owe, what is owed to suppliers and outstanding course fees. Expenses use 30 categories in 8 groups that mirror the client’s own chart of accounts.
06Courses, clients and gear
From Discover Scuba to Divemaster, and every wetsuit in between.
01
PADI courses.
Each course shows progress module by module (confined water, open-water dives, knowledge reviews) alongside payments, PADI fees and certification dates.
02
Clients.
Nationality, hotel and room, PADI qualification and number, in-house and minor flags. Returning divers are found as you type, with their full dive history and a running balance.
03
Gear, tanks, boats.
Kit is counted by size, condition and availability. Service dates are tracked, and anything overdue or due within 30 days is flagged.
1Service due: overdue or within 30 days2Available units against stock, by size3An overdue service, flagged in red
On the boat, not just at the desk.
Every screen works at phone width, so instructors log divers and check the day from the dock.
07Their brand, their server
It looks like theirs because it is theirs.
Scuba World’s own logo heads every screen, and their sign-in opens on a slow aerial loop of a Mauritian lagoon that we produced for them. In October we refined the interface for their team: calmer, denser and easier to scan in a bright reception.
01
One accent colour.
Nine accent hues became ink and greys, one lagoon accent, and red only for real problems such as overdue, unpaid or a loss.
02
Built for scanning.
Compact type, tabular figures for every amount, hairline borders instead of heavy shadows, and a ⌘K menu to jump anywhere.
03
Light by default.
Light suits a bright reception desk, and a separately tuned dark theme is one click away.
On infrastructure they own.
In July we moved the platform off a free cloud tier onto the client’s own server: the same database platform, self-hosted, with a custom domain, HTTPS and automatic deploys. Staff logins came across with their password hashes intact, so nobody had to reset anything.
- 01Copy business data and staff accounts, password hashes included
- 02Load through the server’s container, so the database is never exposed
- 03Audit every table’s row count against the source
- 04Switch over, with the old project kept read-only for a one-line rollback
08Beyond the brief
The tools that keep it theirs.
The brief was the system. These came with it, so the client can run, move and extend it without depending on us.
One-file database bootstrap
A 1,420-line script rebuilds the schema, security policies, views and reference data on any Postgres server.
Runbook with a rollback plan
Four phases from infrastructure to post-cutover checks. Rolling back means changing one URL.
Documentation generator
One source produces four Word specifications: product requirements, UX and UI, technical design and functional.
A written design system
Tokens, the colour budget, type scale and components, so the next screen stays consistent.
Bespoke sign-in imagery
An aerial lagoon still and a seamless video loop, made with AI tools and optimised to about 3 MB each.
Hardened container
A multi-stage build that runs as a non-root user, with automatic deploys on merge.
Their data, before day one
Dive sites, commission rates and 76 gear lines from their STOCK GEAR sheet, loaded ahead of the first login.
09Effort and results
About 135 hours, from their workbook to their own server.

An agency would typically quote this scope, with 30 screens, role-based security, PDF invoicing, financial reporting, a data migration and a design system, as a multi-month project.

client-owned code, data and infrastructure
- One source of truth. Each dive is entered once. Income, invoices, balances, diver statistics and the monthly P&L all come from that entry.
- Live numbers. The manager sees the day’s revenue, profit and money owed during the day, not at month-end.
- Invoices in one click. Client and daily batch invoices come out as PDFs on demand.
- Clear accountability. Each role sees only what it needs, and the database enforces it.
- Built for the target. The project was scoped to cut daily admin from about two hours to under thirty minutes.
