BUILT IN-HOUSE · THE QS ENGINE

The platform behind better prices.

Broking has traditionally run on spreadsheets and inboxes. We built our own software — the QS Engine — so lists are priced quickly, accurately, and entirely inside our own four walls.

WHAT IT DOES FOR YOU

An advantage you feel in the quote

Every capability below exists for one reason: to turn your list around quickly, and to price it accurately.
Lists cleaned in minutes
The QS Engine ingests any format and normalises thousands of lines — part numbers, quantities, date codes — without the manual re-keying that slows large lists down. That's why quotations come back quickly, even on long lists.
Real-time market pricing
Live aftermarket data feeds straight into valuation, so offers reflect what a part is genuinely worth today — not last quarter's guesswork. Accurate pricing in both directions: stronger offers to sellers, fair quotes to buyers.
Instant match alerts
Tell us the parts you need urgently and we flag them in the QS Engine. The moment matching stock is offered to us — often before it reaches the open market — you hear about it.
Full trading history
Every previous bid, sale price and market movement is retained, alongside your own preferences and requirements. We price with context — and you never have to explain your business twice.
Shipments tracked end to end
Every movement and milestone is recorded in the app, from collection booking to delivery. When you ask where your stock is, the answer takes seconds — not a round of phone calls.
Smarter BOM sourcing
Incomplete list? The QS Engine pulls missing part information from our databases and suggests approved alternates where a line is obsolete or unavailable — so a partial BOM still gets a complete answer.
PRIVACY BY DESIGN
Your lists stay in our system.
The QS Engine is entirely our own — built in-house, not in partnership with other distributors, brokers or competitors. Once your list is in our system it stays there: we don't pass it to other traders, list it on third-party marketplaces, or sell it on. Nothing is shared without your consent.
