About Marbles

We exist because
accounting software
stopped improving.

Marbles is accounting software built in Sydney to do the accounting itself - reconcile, code, chase, run payroll and prepare BAS - on our own AI-native ledger. We're part of Covalent API - we build ERP and AI systems for some of Australia's largest enterprises.

The company

Covalent API Pty Ltd

Marbles is a product of Covalent API Pty Ltd, a Sydney based software company building AI native core systems for Australian enterprises. Our technology platforms are used by some of Australia's largest firms.

Marbles is our answer to a question: why has accounting software kept getting more expensive without getting meaningfully better?

We are ISO 27001 certified, independently audited by Compass Assurance Services Pty Ltd. We are headquartered in Sydney.

What we believe

Built on a few
strong opinions

i.

Software should get smarter every year, not just more expensive.

Incumbent accounting software got more expensive every year without getting meaningfully better. Marbles charges one all inclusive monthly fee - and the service improves every month you’re with us.

ii.

Automation should remove work, not shift it around.

AI should reconcile transactions and remove work completely. Not suggest categories for you to click through one by one.

iii.

Australian businesses deserve Australian hosted software.

All data lives in AWS Sydney. ISO 27001 certified. Your financial data is kept in Australia.

iv.

Pricing should be transparent and stable.

A free plan that stays free. Paid plans priced below the equivalent Xero tier, with no price rise every year. No hourly billing, no surprise invoices, cancel any month.
