You approve invoice issuance and authorize tax-return drafts in the signed-in
Melso app. An assistant can prepare the work and give you the link, but the
approval belongs to you.
Tax returns
Read the draft and confirm the exact version. Your authorization starts a
service case for Melso’s professionals to review and file the included return
with the required authority. They will contact you if information is missing.
An unchanged authorized version proceeds; a changed version needs your
approval again.
Autorizado · en revisión (authorized, under review) remains until the professional records the actual result; it is not a filing receipt. The actual external reference
and receipt establish the filing result. An estimate or an AEAT import file
does not establish submission.
Invoices
A prepared invoice is an unnumbered draft. Inspect the customer, dates, and
line items in the saved preview before approving issuance. A correction to an
issued invoice starts a new draft for review; it does not rewrite the issued
document’s frozen record.
External AI clients
MCP clients can return approval links. No customer MCP tool approves, files,
or pays a return. Recording a confirmed invoice payment records money you have
already received; it does not charge a card or transfer funds.

MCP permissions for integration boundaries.
