Back-office work that still agrees with the trip record

GTOS, from Voraal, is the operating system for the corporate account: the client, the traveller and the agency desk share one trip record, including cost, invoices and an audit trail. Folio6 is accounting and revenue intelligence software for travel businesses, designed around how agencies record and report. Together they address the two sides of back-office work — the client-facing trip file and the agency's own books — without pretending they are already one merged product. We do not claim a live, production integration between GTOS and Folio6 beyond being products of the same group. How they are designed to work together is a conversation for a demo.

GTOS is built on operating experience across 100,000+ trips.

What the agency back office has to reconcile

It has to reconcile tickets and hotels with supplier charges, client invoices, refunds and any credit terms the account holds. It has to do that in more than one currency in many agencies. It has to answer a client who is looking at a CFO report or an invoice on the same record the desk used in Control Tower.

Mid-office sits between booking and this finance work: quality checks, changes, and the handover of a clean file. Back-office is where that file meets accounting.

Rezencia addresses reservations and sales for the agency's own booking and hospitality work. It is part of the same family, and again we do not blur it into a GTOS feature list or invent a certified link.

Honesty about scope

This page is not a claim that GTOS is a complete agency general ledger, and it is not a named connector list for accounting packages. Accounting integrations are scoped during implementation, without published certifications. Avunzo is a B2B travel API designed to connect content and booking flows to your own channels; it is not yet live on production, and early access is available on request. It is not a back-office finance system.

USD is the main currency on this site. Pricing for GTOS, and conversations about Folio6, is in USD and available on request. Each client sees only its own data in GTOS. We do not claim certifications we do not hold. A demo can map which layer you need first: the corporate trip record, mid-office operations, or travel accounting.
