Invoicing in Guam
A business registered in Guam charges Sales tax at 4% and invoices in USD. Unlike a value-added tax there is no input-credit chain, so the tax sits on the sale itself and the document has to state it plainly. DocsOrigin takes the rate, the document names and the numbering conventions for Guam from the registry.
Invoicing in Guam is free forever with DocsOrigin: every document type, every export, no card and no trial.

How reliable is this figure
Graded medium: this rate is believed current but has not been re-checked against an official Guam source recently. Verify it before issuing, and override it in your settings if it has moved.
Whatever the grade, your own setting always wins — a rate you enter overrides the registry everywhere, including on documents already dated in the past.

Tax identifier
On a document issued in Guam the identifier is labelled Tax ID. It is printed in the header of every tax document, isolated left-to-right so it reads correctly in any interface language.
No structural check is applied for Guam: the format is accepted as entered, because a wrong rule that rejects a valid number is worse than no rule.
Numbering
Guam does not impose a strict national sequence, but DocsOrigin still numbers sequentially per document type and per year, because a gap is the first thing anyone auditing you will ask about.
Prefix, padding and yearly reset are configurable per document type, and the series is kept separately for each type.

What tax rate do I charge in Guam?

Which document do I issue to a customer in Guam?
The document set recognised in Guam is listed above, under the names used locally. For a paid sale the usual document is 税務請求書, and a mistake on an issued document is corrected with a credit note rather than an edit.
Does DocsOrigin cost anything in Guam?
No. DocsOrigin is free forever for businesses in Guam as everywhere else: no subscription, no card, no trial, no per-document fee and no export fee. Optional professional services are the only thing that is ever charged for, and they are quoted per project.
What if the rate for Guam is wrong or changes?
Set your own rate in the business settings and it overrides the registry immediately, for new documents and for any date. Rates are applied by document date, so an old document keeps the rate that applied when it was issued.
Also billing in USD
The currency is shared, but the tax, the document names and the numbering rules are not. Each of these has its own entry.
