Who you bill, who bills you, and everything between you.

Add someone once as a customer, a supplier or both, with their email, phone, contact name, address and tax number. Those details flow onto your invoices, and each record keeps its own history of what has happened.

The difference

The usual way

Details live in too many places

An address in an old email, a tax number on last year's PDF, a phone number in someone's mobile. Every new invoice starts with a hunt.

With Zelvorm Books

One record for each relationship

Everything about a customer or supplier is on one page, and it's used automatically wherever that name is picked.

How it works

  1. 1

    Add them, or import a list

    Type them in, or upload a CSV. Names already in your books are skipped, so you won't get duplicates.

  2. 2

    Use them everywhere

    Pick a name on an invoice, a bill or a payment and their details come with it.

  3. 3

    See the whole picture

    Open a record to see its documents and timeline, and turn payment reminders off for one customer if you need to.

What you get
