Stop stitching the truth together

The messy middle is where margin leaks and trust breaks. DAY ONE turns pipeline, delivery, and finance into one governed Prospect to Payment chain.

  • Billing that matches the work, with traceability back to time, cost, approvals, and contract rules.
  • Audit-ready WIP, so month end is a process, not an investigation.
  • Earlier margin warnings, because delivery and finance stay connected in the same operating view.
  • AI you can count on, grounded in structured delivery and finance data with source links and audit trails.

“DAY ONE has helped us manage our engagements more efficiently, giving us better control and reliability for client outcomes. The DAY ONE team is very supportive and responsive; working with them has been great!”

Nicholas Moustrides COO, Kaizen ICT

“DAY ONE has become the backbone of how we run our projects. It gives us clear visibility on budgets, margins, timelines, and delivery health, which means we catch issues early and make better decisions. It’s simple to use and powerful where it counts, and it has made a real difference to how we operate as a growing consulting firm.”

Christopher Nugent Co-founder, We Lead Out

“DAY ONE has helped us to identify and automate several of our processes from the old system, driving significant efficiencies particularly in our invoicing cycle which in turn is benefiting our cashflow”

Matt Clohessy CFO, Rowland

“DAY ONE has given our business a layer of visibility and governance that was not possible without a fully integrated operating environment. The team at DAY ONE treat their customers like partners actively working on how to get the most out of the application.”

Peter Moustrides CEO, Kaizen ICT

“DAY ONE has transformed our day to day operations by bringing focus, transparency and predictability to every part of our delivery process.”

Clancy Brodrick Co-founder, We Lead Out

“In Professional Services, it’s near impossible to have visibility from quote-to-contract-to-invoice. With DAY ONE, we know where our pipeline is at, where our contracts are, employee timesheets, invoices and projects, all in one central hub. DAY ONE runs our business, so we’ve got more time to work with our clients.”
