The brief
What the project had to do
An accounting practice runs on trust and paperwork. GG101 needed clients to book the right service, send documents safely and see where their work stands. Staff needed to handle bookings, tasks, quotations and invoices from one dashboard.
- Book any of eight services online, at times staff are really free
- Keep each client's documents and messages private to them
- Show clients the progress of every service
- Quote, invoice and take payment online
- Give clients, staff and admins the right access, and nobody else

What AussyPrompt ONE did
One app, planned as one
Austin described the practice to AussyPrompt ONE once. ONE planned the website, the Client Portal and the Admin Dashboard as one system on one database, in six phases. Claude Code then built each phase from ONE's build pack.
Roles
Clients, staff and admins, each with their own portal and their own permissions. Row-level security in Supabase enforces them in the database itself.
The data plan
Clients, services, bookings, availability, documents, messages, tasks, quotations, invoices and payments, and how each one links.
Every screen
The public site and booking wizard, the Client Portal for services, documents and messages, and the Admin Dashboard for clients, staff, tasks and reports.
Automations
A booking checks real availability and sends notifications. Quotations become invoices, invoices become PDFs, and payments come in through PayFast.
Six phases
Foundation, booking, the Client Portal, admin operations, quotations and payments, then testing. Every phase ends with something that works.
Checks
A security audit, a test of every role against every page, browser tests with Playwright and automatic checks on every change.
The result
See it live
Eight services, ready to book
Accounting and bookkeeping, tax, payroll, compliance, HR, legal, business support and a corporate package, each with what's included.
Booking with real availability
A step-by-step wizard with a running booking summary. Clients pick a service and a time when staff are actually free.
How GG101 works with clients
An approach page that sets expectations before anyone books.
A private Client Portal
Clients sign in to follow their services, send documents and message the team. Staff and admins use the same app, each with their own dashboard.
How it was built
Claude Code built GG101 as one Next.js app on Supabase, phase by phase, from ONE's build pack.
- Supabase for sign-in, the database and private document storage
- Row-level security on every table, so each client sees only their own records
- Quotations, invoices and PDFs, with online payment through PayFast
- Playwright browser tests and automatic checks before every release
- Hosted on Hostinger at gg101accounting.com
What they have now
- A live website where clients book any of eight services online
- A Client Portal for services, documents and messages
- An Admin Dashboard for clients, services, staff, tasks and reports
- Quotations, invoices and payments in the same app
Austin planned this project with the pre-launch version of AussyPrompt ONE on his own machine, then built it with Claude Code. Screens are from the public website. Published with GG101 Accounting Services's permission.
