How Bill One Works for You All your invoices consolidated
and centralized, in the cloud

Your vendors upload, email, or post their invoices. Bill One receives them, digitizes them, and adds them to your cloud database. Then use Bill One to approve, pay, and manage.
No more opening envelopes and emails. No more scanning and data entry. We've got you covered.

  • Paper = analog. It gets
    circulated, lost, and eats up
    your time. Go digital and lose
    the mess.

  • Communication across multiple
    locations and departments, is a
    constant chore. We'll get you

  • Accounting can't settle the
    invoice if one person's holding
    up the process. Bill One helps
    you remove the roadblocks.

Streamlined Workflows Go digital and make month-end closing a breeze.
Simply direct your vendors to Bill One.

Bill One's Main Functions Bill One streamlines the operations of all departments
handling invoices. Not only the Accounting Dept. will benefit.

Proxy receipt

Receive all your invoices online, whether in digital or paper format. Have your vendors post their paper invoices to Bill One and we’ll receive them on your behalf and scan them for you. Or have invoices sent to a dedicated Bill One address and we’ll automatically upload them to your account. All your invoices will be centralized, with no extra burden on your vendors.

Highly accurate digitization

Enjoy extremely accurate digitization from our proprietary AI + OCR combination. This has been developed over many years through business card digitization and human checking at our scan centers in Singapore, Thailand, and Japan. Bill One currently handles invoices in English, Thai, and Japanese.

Streamlined workflows

Bill One streamlines your approval processes from receipt of invoice through to payment and reconciliation. Receipt notifications, reminders, and notes can also be added, helping to centralize workflows, speed up monthly closing, and make audits go more smoothly.
