Referral Process
We understand not all information may be available with the partners, this is why we take the responsibility to liaise with the clients directly to deliver the details required. Through being flexible with communication and including partners when requested, this ensures we do not burden partner further.
We understand that our stakeholders are extremely busy within their own line of work and as such, we believe in a minimalist approach. Taking in the bare essentials and liaising with the clients directly to take the guesswork out.
New Builds & Developments
When it comes to scaled-projects requiring a larger quantity of depreciation schedules for either builder or developers, the process is simple with Duo QS only requiring only few pieces of information to execute a project expeditiously.
At Duo QS Construction Estimators, we pride ourselves on turning around reports in an unprecedented time frame. Generally reports take 10 businesses days to complete in the busiest of seasons however can work closely with project managers to deliver outstanding reports in record time.
Property Investors
Investors acquiring property, both new and old, seek to understand the value-add that tax depreciation can offer them. At Duo QS, our goal is to ensure investors make the most out of their investments. This is done by offering a complimentary consult which will allow the investor understand the projected cash-flow the property will yield through depreciation, simultaneously providing a guarantee of the value Duo QS' reports will add.
