Make money work.

Fragment is the financial system for agents. Programmable money that bills, pays, and accounts for itself.

- [Ledgers](https://fragment.dev/product/ledgers.md): Model any funds flow, turn it into code, and never get another balance wrong.
- [Payments](https://fragment.dev/product/payments.md): Move and track money in one API call.
- [Recon](https://fragment.dev/product/reconciliation.md): Turn conversations, docs, and code into financial objects.

## The control plane for your financial code

- [Entry conditions](https://fragment.dev/guides/configure-consistency.md#entry-conditions): Authorize transactions directly from the ledger.
- [Typesafe SDKs](https://fragment.dev/api-reference/ledger-sdks.md): Generate an SDK from your schema, so config and code never drift.
- [MCP](https://fragment.dev/api-reference/mcp.md): Let agents read and write payments through MCP.
- [Double entry](https://fragment.dev/guides/accounting-101.md): Every transfer balanced. Every balance correct.

## Use cases

<a id="use-cases-healthcare"></a>

### Healthcare

Automate patient billing, payment posting, and claims reconciliation.

Fragment lets agents reconcile insurance payments to claims, apply adjustments, keep patient balances accurate, and handle collections, refunds, and reversals.

<a id="use-cases-logistics"></a>

### Logistics

Automate shipment billing, carrier payments, and freight accounting.

Fragment gives your agents a unified view of each shipment so they can pay carriers, adjust invoices, and match partial/bulk payments to the right shipments.

<a id="use-cases-insurance"></a>

### Insurance

Automate premium billing, claims payments, and bank reconciliation.

Fragment lets your agents track claim payments, pay premiums, account for admin fees, and allocate credits to the right plan or member.

<a id="use-cases-fintech"></a>

### Fintech

Turn agents into financial operators.

With guaranteed correctness, agents can monetize all the refund, reversal, collection, claims and clawback flows they used to hand off to humans.

## [Customers](https://fragment.dev/customers.md)

> Fragment helps our agents navigate complex money flows. Agents propose and test payment flows, investigate anomalies, and run reconciliation and close workflows against it.
>
> [Whop](https://fragment.dev/customers/whop.md)

> Fragment is the control plane for our coding agents. The agent decides what to do. Fragment decides what's allowed.
>
> [Ramp](https://fragment.dev/customers/ramp.md)

> We used to worry about missing payments and edge cases. With Fragment, we set it and forget it. No FinOps intervention, recon or wild bug chases. Fragment gives us peace of mind.
