Invoice lifecycle

## Every verb you actually use.

Real-world invoicing has more states than draft and paid. TitanLedger ships them all as first-class endpoints.

01

### Issue

Create the invoice from an estimate, a project milestone, or scratch. Auto-numbered, draft-state, branded PDF ready.

02

### Send

PostFrame delivers the invoice email with PDF + PayGate pay link. Opens and clicks tracked, so you know it landed.

03

### Approve / Reject

Customer approves via signed token link — no login required. Or rejects with a reason and you re-issue in seconds.

04Paid

### Bill / Pay

Customer pays via PayGate — card, ACH, multi-currency. Funds settle to your account, activity logs to ClientForge.

+ Convert

Estimate → Invoice

One-click from BidForge. Same line items, no retyping.

+ Void

Reverse issued

Void with a full audit trail. State preserved for accounting.

+ Refund

Pay customers back

Capabilities

## Real books for real businesses.

The financial hub for everything you sell — invoices, expenses, aging, currencies, and the audit trail behind all of it.

### PDF Invoice Generation

Branded PDFs with your logo, colors, terms. Generate on-demand for any invoice. Customer attachment + downloadable from the pay link.

### Pay via Signed Token

Customer clicks the pay link and approves with a one-time signed token — no login required. PayGate handles the actual transaction.

### Expense Categories

Build custom expense categories. Track spend against projects. Roll up by category for tax season. CRUD endpoints make automation easy.

### Aging Reports

Built-in 0/30/60/90 aging buckets. Know exactly who's late and by how much. Auto-fire reminder emails via PostFrame on configurable cadences.

### Multi-Currency

USD, CAD, EUR, GBP, AUD — issue invoices in your customer's currency. PayGate handles the FX. Books reconcile in your home currency.

### The Money Hub

Estimate accepted in BidForge → invoice in TitanLedger → paid via PayGate → activity in ClientForge. Four apps, one money flow, zero copy-paste.
