Your day at a glance — clock-in, calendar and team presence

Your day at a glance — clock-in, calendar and team presence

Most teams don't have a tools problem. They have a too-many-tools problem.

Most growing companies run on a patchwork: one app for HR, another for projects, a spreadsheet standing in for a CRM, a chat thread for announcements, and passwords scattered across inboxes and sticky notes. Every tool works on its own — but nothing works together. Data sits in silos, onboarding drags, and no one can see the whole picture.

asDayOne started from a simple idea: the software you run your company on should be as connected as the company itself. So we built one platform where your people, your work and your customers live side by side — with a single login, a single search, and one source of truth.

One platform. One login. One source of truth — for every team in your business.

One connected system

Your business isn't built from silos, so your software shouldn't be. Every module shares the same data, so nothing slips through the cracks.

Shaped around real work

From clock-in to closing a deal, asDayOne is built around what people actually do each day — not around an org chart or a feature list.

Clarity over clutter

One search, one calendar, one place to look. We cut the tab-switching so your team keeps its momentum.

Ready from day one

New hire, new project, new client — everything is set up to be productive from the very first day. That's the whole idea behind the name.

Everything your business runs on, in one place.

Eight modules on one shared foundation. Turn on what you need today and add the rest as you grow.

HRM

Employees, attendance, leave, payroll and offboarding — the full people lifecycle.

Projects

Plan work, assign resources and track progress from kickoff to delivery.

CRM

Contacts, companies, deals and loops — turn conversations into customers.

Documents

One secure home for every file, with tags, owners and version history.

Announcements

Keep the whole company in the loop with targeted, scheduled notices.

Passwords

Share access securely across the team — no more spreadsheets of logins.

Finance

Keep invoices, claims and the numbers together in one connected ledger.

PerformanceBeta

Set KPIs, run reviews and track results with built-in goal tracking.

And the essentials that hold it all together — universal search, a shared team calendar, timesheets and daily reports, live member presence, and multi-language support.

Built to be all-in-one — and built to be trusted.

asDayOne isn't a bundle of separate apps stitched together. It's one system, designed and supported close to home.

    Not separate apps with integrations bolted on. asDayOne runs on one data model, so your HR, projects and customers actually talk to each other.

  • Local by design

    Built and supported from Hong Kong and Singapore, hosted close to your team for fast, reliable access — and shaped for how businesses in the region actually operate.

  • Secure by default

    From an encrypted password vault to role-based access and privacy practices aligned with the PDPO, your company's data is protected at every layer.

  • Backed by an experienced team

    asDayOne is built by Visible One, a Hong Kong and Singapore digital studio building software and running operations for businesses since 2008.
