One Price List, Six Jurisdictions
The list was built where the business started. It goes out unchanged to the other islands because nothing in the transaction suggests it should not — same currency, same language, same group.
Expanding to a second country normally announces itself. You quote in a different currency, somebody sets up a conversion, an accountant asks a question, and in the noise of all that the fact that a different tax regime now applies gets noticed. The currency is doing you a favour: it is a tripwire.
Across the Eastern Caribbean there is no tripwire. Six countries share one currency, and a business opening on a second island keeps the same price list, the same document templates and the same instincts — because nothing in the transaction looks different. Everything else has changed.
What differs, in the shape that matters
Not just the standard rate, though that varies from 12.5% at the low end to 17% at the high end. The harder part is that each country draws the line around tourism somewhere different:
- One has no reduced band at all — it abolished the one it had by folding it into the standard rate, which is the opposite of every neighbour.
- One extends its reduced band to restaurants as well as accommodation, so it reaches past tourism into ordinary domestic trade.
- Two include diving alongside accommodation.
- One applies its reduced band to accommodation only — the narrowest.
- One runs three rates, with different treatment for rooms, for restaurant food and drink, for watersports, for tours and for heritage admissions.
There is no band assignment in this post, and there will not be
Which country is which, and which band a particular supply of yours falls into, is a question for your adviser — and the definitions genuinely turn on things like how many bedrooms a property lets and whether transport inside a tour package was direct or indirect. What is safely publishable is the shape: six neighbours, one currency, and no two of them agreeing on where tourism ends. The specific figures are on our Eastern Caribbean market page, each read at the statute and dated, with the reason you should still check them yourself.
The same room, the same dive trip and the same restaurant meal are taxed differently in six countries whose money is identical. Nothing in your ledger will tell you which one you are in.
Where the price list actually breaks
Three failures, and the third is the one that survives longest because it looks like a success.
| What happens | Why nobody catches it |
|---|---|
| The list goes out unchanged to island two | No conversion, no new currency, no prompt. The document looks exactly like the one that was right yesterday |
| A mixed invoice is recorded at one rate | Where the rate is a property of the DOCUMENT rather than the line, the mix is lost at capture and every later split is an estimate |
| The group total looks trustworthy | Because no conversion appears in it. A consolidated figure across a shared currency has the reassuring smoothness of a single-country number, and it is six different answers added together |
What a system has to hold, which is less than a band engine
The instinct is to want software that knows the rules. That is the expensive answer, it is the one that goes stale, and it is not where the value is. Three cheaper properties do most of the work.
The rate on the line, not on the document
Net, tax and gross split at the point of capture, per line. This is the single change that turns a mix from an annual reconstruction into a record — and it is what a group billing rooms on one island and restaurant covers on another actually needs.
Attributes of the thing being sold, held as fields
Where a treatment turns on a fact about a property — how many bedrooms it lets, what activity a site is licensed for — that fact belongs on a record with a date rather than in the knowledge of whoever runs the estate. It changes when a building is extended, and the change has consequences.
Every island its own position
Locations and entities each holding their own stock, numbering and approvals, with reporting per island as well as consolidated. Because the consolidated number is the one that hides the problem.
The evidence that a supply was what you called it
Held against the transaction and retrievable by it. Where a reduced band attaches to a named activity, the qualifying evidence is what a later question is about.
A rate that resolves from the island
Not built. One default per organization per tax type, so a group manages the difference at the line and in its own discipline rather than through configuration. Ordinary work, commissionable with a written specification, a timeline and a price.
Knowing which band a supply falls into
Not ours, at any price. Encoding six countries' tourism definitions — including one that is a bedroom threshold — into software that then applies them silently is how a finance team stops asking their accountant. The failure mode of band logic that is nearly right is worse than not having it.
The check, and it takes one product
-
Pick one thing you sell on two islands
Write down the rate you actually charge for it in each. If the two are the same, that is either correct or the finding — and which one it is costs a single conversation with your adviser rather than a demonstration from a vendor.
-
Ask where that rate lives
On the line, on the document, on the customer, or in a spreadsheet somebody maintains. This answer tells you whether your mix is a record or an annual reconstruction, and it will be the same answer for every island you add afterwards.
-
Ask who would notice if it were wrong
In most operations the honest answer is "the auditor, eventually" — and eventually is where the cost accumulates. There is no exchange-rate movement here to draw anybody's attention, which is the whole reason this is worth ten minutes now.
One last thing worth knowing before you configure anything from an official source: on at least one of these six islands, the revenue authority's own live site currently publishes figures that the law repealed at the end of 2023. That is not a reason to distrust authorities generally — it is a reason to read the statute, and to ask any vendor, including us, where their figure came from and when they last checked it.
What is built, what is not, and what we would decline is on the Eastern Caribbean market page, with all six rows and their sources. Why a shared currency is a worse signal than no currency at all is the currency that tells you nothing, and the sharpest single definition in the group is the rate decided by a bedroom count. The same divergence inside one country — where the unit of a rate is a sector rather than a place — is Jamaica.
