Finance Tools Tools

This category covers the money layer: taking payments, running subscriptions, connecting to bank data, and the accounting that follows.

For payments, the practical decision is how much of the regulatory and operational burden you want to outsource. Full-stack processors handle card data, compliance scope, fraud tooling and payouts behind one API — expensive per transaction, and dramatically cheaper than doing it yourself. What varies most between them is not the API but the coverage: which countries, which payment methods, and what happens when a payment fails.

Billing is where teams underestimate the work. Subscriptions sound simple until proration, upgrades, dunning, tax and refunds arrive. It's worth checking whether your processor's billing layer covers your model before building your own on top of raw charges.
