The short answer
What to know first.
A licensed operator pays UWA or RDB, and Sail, as the destination management company on the file, holds the official authority receipt. You receive written proof that the permit exists in the correct names, for the correct date and sector; the guest carries a matching passport and the permit in the form the park currently requires. A lodge voucher, a screenshot or a pro-forma from an unknown agent is not a permit.
At a glance
The planning brief.
Who pays
A licensed local operator pays UWA or RDB. Permits are not a gate purchase on trek morning.
Who holds the receipt
Sail holds the official authority receipt on the operating file, produced whenever an audit asks who paid.
What you receive
Written proof: passport names, date, sector or park, and confirmation the authority has receipted payment.
What the guest carries
A matching passport and the permit in the form the park currently requires. Not Sail's internal receipt.
01
The payment chain should stay short
Gorilla permits are issued by two authorities: UWA in Uganda and RDB in Rwanda. The money that secures the permit is paid by a licensed operator into the authority's own channel. Sail sits on that channel as the East African operating house; you sit with the client; the guest sits with the forest.
That order matters because gorilla inventory is no longer something an operator can reserve unpaid while a Mara camp sits on request. A permit is confirmed when it is paid and receipted. Lengthen the chain — an unlicensed seller, a social-media broker, an invoice with no authority reference — and you no longer know who holds the only document that counts.
02
Three layers, kept distinct
The official receipt is the record generated when UWA or RDB accepts payment for a specific permit. It sits with the operator who paid; it is not the guest's trekking permit and it is not your client invoice.
On a clean file you should see three layers: the authority receipt, held by Sail; the permit record, carrying guest names, date and — in Uganda — the sector or park; and your proof pack, enough to brief the traveller without making them courier the operator's accounts. Buhoma, Ruhija, Rushaga, Nkuringo and Mgahinga are not interchangeable labels on that record. Tariffs are set by the authorities, are not restated here, and are confirmed at booking.

03
What you should insist on seeing
You do not need to store the original authority receipt when Sail is the licensed operator on the file. You do need proof that it exists.
Names
Passport names exactly as they will appear at briefing.
Date and sector
The trekking date locked and, in Uganda, the sector or park locked with it. A receipt without a sector is not an operating plan.
Payment
Confirmation that the authority has been paid, not merely that an agency has been invoiced.
The permit form
What the guest will actually present — printed, electronic or both, according to current park practice.
04
What the guest carries on trek morning
Rangers at Bwindi, Mgahinga and Volcanoes match a person to a paid permit and run a briefing. They are not there to inspect your commercial file. The guest should travel with the passport whose names match the permit, and the permit in the form the park currently requires — practice has moved toward electronic issue in Uganda, while Rwanda has long worked from an official permit record. Sail briefs the specific requirement with the final documents rather than assuming last year's print-out still governs.
The guest should not carry cash for the permit at the gate — foreign non-resident permits are paid before arrival — and they should not produce Sail's internal receipt for the ranger. That document belongs on the operating file.
05
Unofficial bookings, and a genuine receipt in the wrong sector
Permit fraud is rarely theatrical. It is usually a plausible PDF and a seller who would not appear on a UWA or RDB receipt. Weak points include a booking outside the licensed-operator channel, a Rwanda date promised without RDB-side confirmation, and a held name after unpaid holds have ended. If no one has paid, no one holds anything.
There is also a quieter failure: a genuine receipt for Rushaga while the stay is sold in Buhoma. Briefing points are sector-specific and cross-forest transfers are not a small detail. Keep the receipt, the sector and the lodge in one sequence, or the payment is real and the morning still fails.
Questions travellers ask
Useful answers, before you decide.
Does the guest need a copy of the UWA or RDB payment receipt?
No. They need the permit evidence rangers currently require and a passport that matches it. The official payment receipt stays on the operator file, and you receive proof that it exists.
Can the client book a permit themselves and send Sail the PDF?
Only if it is a genuine authority issue in the guest's names, for the right date and sector, and can be verified. Unofficial documents are the usual fraud surface; it is calmer to let the licensed operator pay and receipt the permit on the same file as the lodge and transfers.
How do I explain this without discussing price?
Point the client to the live tariff article for figures, then talk about process: the licensed operator pays, Sail holds the receipt, you receive proof, and they carry what the rangers need. The tariff is confirmed at booking.
