Don't trust us.
Check us.
Below: the government registries we're on, the staged payment schedule that means you never pay half of an open-ended number up front, and how to tell a real TAS invoice from a forged one. Five minutes, no phone call — our participation is not required.
Check the registration.
Our PT is on the public record. You don't need our permission, our cooperation, or our version of events. The legal name and NIB are printed in the footer of every page on this site — run them through the AHU (Ministry of Law and Human Rights) and OSS (business licensing) public registries:
AHU company profile search — type PT Technology Art Service into the search field.
OSS licensing portal — menu “Cek NIB & Perizinan Berusaha”, enter NIB 2601260039886.
Neither registry hands out a permalink to a company record — you run the check yourself, on the government's own site. Which is rather the point.
If anything in those registries disagrees with our footer, don't shrug and close the tab — tell us. It means someone is trading on our name, and we want to know before you do business with them.
We don't take 50% up front.
The first money we ask for is half of a fixed design fee — not half of your budget. Design locks the bill of quantities and the price; everything after is staged against that document:
Design — 50 / 50. Half to start, half against the locked BoQ and drawings. A fixed fee, quoted up front.
Equipment — 100% on order. Paid against the locked BoQ — exact models, quantities and the final number on paper before anything is bought. Import orders don't ship on promises, so we don't pretend otherwise.
Installation — 50 / 50. Half to mobilise the crew, half on the completed install.
Commissioning — 50 / 50. The last payment lands after the system runs at full load — your opening night, not our lab.
How to know a bill is really from us.
Invoice fraud isn't a hypothetical here; it's a genre. Quotes "from TAS" with a stranger's bank account have been sent before and will be sent again. Three rules, no exceptions:
Every real invoice comes from a@tas.ac. One address. There is no "my other email", no "our finance department's Gmail".
Bank details arrive by WhatsApp or email when you raise the PO — never printed in a public PDF. A letterhead with account numbers on the open internet is a forgery kit, which is why our vendor pack doesn't contain one.
If a bill reaches you from any other address, or the account name isn't our PT, stop. Message the number in our footer before any money moves. We'd rather answer ten false alarms than have you pay one real fake.
