We provide Data Plumbing for accounting firms.  Our pipes are smooth steely titanium carrying high-integrity and accurate accounting data safely and securely for the world’s accountants.


The accounting software market is crowded: there are an increasing number of accounting software programmes and general ledger accounting practice tools.  This creates a fragmented market and frustration and pain for accountants who need access to their client’s accounting data.


We spotted this problem early and have been researching and solving for it since 2013 and we now understand it like no other.  We know every software product, every version, every vendor and every piece of data – and we know the solution that is needed to bring it all together.


Only a neutral and agnostic player can provide that solution – the accounting Data Plumbing.  That player must not build front-end functionality for the business end user and must be complementary to the accounting software vendor, accountants and other trusted business advisors.


Finally, accountants are the custodians of financial data and they are the key to building robust plumbing – they are at the centre of this world.

Our goal is to be the best in the world at integrating accounting software.  We will know we have achieved this when we are the industry standard Data Plumbing solution.

We are a team of thinkers, problem-solvers and doers, deeply fascinated by the conundrum we have chosen to work on – it’s a dirty data challenge, and we love it.

We believe that accountants and business advisors are the key to a powerful, well-functioning world.  Our role is to bring accountants the data they need, whenever and however they need it.

We are a globally-focussed business with our head office in Wellington, New Zealand, our Australian headquarters in Melbourne and our third UK office on the horizon.


Data Plumbing, is the emerging idea of normalising business financial data and integrating it into the core systems accountants and other financial services industries use – it is increasingly the key to unlocking higher value propositions for the business end user.

The accounting software industry is at its most competitive point in history.  In most markets, fragmentation, not consolidation is the dominant likely narrative for the next 5 to 10 years.  New tools that are unimaginable today will arise to solve new problems tomorrow.

This will increase the requirement for accountants, bankers, and other service providers alike for an easy and efficient way to access, consume and distribute the data.

This opportunity is massive and truly global – we see a world where Data Pipes are the norm for accessing customer financial data whenever and wherever it’s needed.

Data Plumbing is not a fad and is here to stay – someone is going to be the industry standard plumbing provider, and we are the best placed to claim that title.
