In-application Accounting

Subledger is a set of powerful APIs that allow you to quickly build the accounting part of your app.

How it works

It’s like Google Analytics for money. Add Subledger code snippets to your application and financial events will be accounted for as they happen. Now you can see what’s driving (or not driving) your profit without running monthly database queries and fancy spreadsheet macros…your CFO will love it.

Built For Developers

Connect to Subledger via our intuitive RESTful API, Ruby gem and Javascript Library.

Micro-Transaction Billing

Use Subledger to aggregate micro-transactions up to a payment threshold and then use your favorite payment API to process the payment. Bring on the pay-per-use economy!


Need an accounting ledger that can handle super high transaction volumes with 8+ decimal accuracy?
We’ve got you covered.

Real-time Financials

Everyone wants to see where the money is. Subledger is a precise, scalable double-entry accounting ledger which makes it easy to show your customers/partners a live statement of their account and your CFO is going to love the real-time financials!
