Set up Ekwo for Guernsey

Two ways in, and both end the same way: the rules of Guernsey installed in a database you own.

Create your Ekwo Cloud account

The hosted edition, operated for you: the web application and your own instance. No password — Ekwo Cloud sends a code to your address.

Run it yourself

Free, for ever. One command on your own Supabase project applies the schema, installs the Guernsey pack and creates your first company. Nothing is gated.

npx ekwo-os init --country GG

It asks for the rest as it goes: the connection to your project, the chart of accounts where there is a choice, your organisation and your first administrator.

Step by step

The same path as text: every command with Guernsey already on it, and the codes a first invoice is written with. An AI agent helping you reads the same text as Markdown, at /countries/gg/set-up.md.

Ekwo keeps double-entry books in a database you own, with the rules of Guernsey as data. On Ekwo Cloud the Guernsey pack is ready to use, with an account opened in a minute; this page is the other way in, Ekwo OS, the open source core, installed on your own project. It is generated from the Guernsey pack, version 0.1.0; every code on it is read from the pack.

The Guernsey pack is community: contributed, and reviewed by nobody.

Your accountant works in the same books, with their own access, and the pack carries its sources, its version and its status. To find an accountant who works with Ekwo in Guernsey, see the directory or our partners. What Ekwo is, and its limits: the disclaimer.

1. What you need

  • A Supabase project of your own. The free plan is enough to start; Ekwo does not create it, pay for it or have access to it.
  • From its dashboard: the connection string (Connect → Session pooler), the Project URL and the service_role key (Project Settings → API). The key is used once, to create your first administrator, and is written nowhere. The anon (publishable) key, on the same page, is what you sign in with afterwards.
  • Node 20 or later on your machine. Nothing else: no Supabase CLI, no Docker, no clone.

2. Install

One command. It asks for the rest as it goes.

npx ekwo-os init --country GG
  • One chart of accounts: Guernsey reference chart of accounts, 182 accounts.
  • The books are kept in en.
  • A financial year follows the calendar unless you pass --fiscal-year-start YYYY-MM-DD.

The same, with no question asked — every value your own:

npx ekwo-os init \
  --country GG \
  --db-url "postgresql://postgres.<ref>:<password>@<pooler host>:5432/postgres" \
  --supabase-url "https://<ref>.supabase.co" \
  --service-role-key "$SUPABASE_SERVICE_ROLE_KEY" \
  --org "Your Organisation" --company "Your Company" \
  --admin-email "you@example.com" \
  --yes

3. Before you go live

Four settings of your project no installer can reach: turn off self sign-up, keep two administrators, keep the service_role key off every other machine, and read the disclaimer. init prints them; the installation guide explains each.

4. A first invoice

Sign in as the administrator you just created, pick the company, and write a draft. --dry-run shows the entry the database would write, and writes nothing; post books it.

ekwo login --supabase-url https://<ref>.supabase.co --anon-key <publishable key> --email you@example.com
ekwo use "Your Company"
ekwo contact add "First Customer" --country GG --ref customer-1
ekwo doc new --contact "First Customer" --ref invoice-1 --line "name=Consulting,price=1000.00,account=4000"
ekwo post invoice-1 --dry-run
ekwo post invoice-1

A line names its account and its tax by code, never by rate. 4000 is the account the pack names for sales; the chart may carry a closer one for what you sell — services, a reduced rate — and list_accounts lists them.

What the invoice says about your company — its address, its VAT number — comes from the company’s profile, which the MCP tool update_company_profile fills; ekwo init sets only the name.

The pack carries no domestic sale tax, so a line names no tax.

5. With an AI agent

The MCP server lets an agent keep the books as you, under your own row level security, and never with the service_role key. Configuring it, and what an agent must and must not do.

What the Guernsey pack carries

  • Charts of accounts: Guernsey reference chart of accounts (182).
  • 2 taxes, at 0 %.
  • Financial statements: Balance sheet — FRS 102 Section 1A, Format 1, Profit and loss account — FRS 102 Section 1A, Format 1.

What it does not do

  • Nothing is sent to an administration, a Peppol network or a bank by the open source software: transmission is yours, or an operator’s you appoint.
  • What the pack leaves out on purpose is in its README.
