Stop Chasing Payments.
Let InvoiceFlow Collect.
InvoiceFlow automates invoicing, reconciliation, and payment recovery for high-volume sellers and service businesses. Built on Stripe and engineered for idempotent webhook handling, it reduces days-to-pay and eliminates manual reconciliation — so finance teams focus on growth, not paperwork.

Why We Built InvoiceFlow
Agency owners:@stripe is great for payments. It's terrible as your billing system.

No real audit trail. Weak dunning. No automatic reconciliation.
So you end up chasing invoices, debugging failed webhooks, and cleaning up spreadsheets.

The Invoice Problem
Most growing businesses lose revenue to these silent killers
Slow Payments
Average DSO of 45+ days drains cash flow and limits reinvestment
Manual Reconciliation
Hours spent matching payments to invoices across platforms
Lost Revenue
Failed charges and expired cards go unrecovered without automation
Error-Prone Invoices
Manual entry leads to disputes, delays, and compliance risk
How InvoiceFlow Works
From invoice creation to reconciliation — fully automated, fully auditable
Invoice Created
Generate invoices automatically from your CRM, project milestones, or manually. Stripe handles billing and payment collection.
Webhook Received
Stripe sends real-time events (invoice.paid, payment_intent.succeeded, charge.failed). Every payload is signature-verified.
Auto-Reconciled
Payments are matched to invoices instantly with idempotency. Failed charges trigger smart dunning sequences automatically.
Revenue Dashboard
Real-time visibility: DSO trends, collection rates, outstanding invoices, and cash flow projections — all in one place.
Integration Architecture
Built for Finance Teams That Need Reliability
Stripe-Native Billing
Invoices, subscriptions, and one-time charges — all managed through Stripe's infrastructure
Auto-Reconciliation
Payments matched to invoices in real-time via webhook events with zero manual effort
Idempotent Webhooks
Built-in retry resilience and signature verification for every Stripe event
Revenue Dashboard

Webhook Event Handling

Frequently Asked Questions
Do I need an existing Stripe account?
Yes. InvoiceFlow sits on top of your Stripe account — we never hold funds. You maintain full control of your Stripe dashboard, API keys, and payouts.
What happens if a webhook fails?
Stripe retries failed webhooks for up to 72 hours. Our handlers process events idempotently using event IDs, so duplicate deliveries are safely ignored.
Can InvoiceFlow handle subscriptions?
Yes. Growth and Enterprise tiers include full subscription lifecycle management — trials, upgrades, downgrades, cancellations, and proration.
How do you handle sensitive payment data?
We never touch raw card data. All payment processing uses Stripe's tokenized infrastructure. Webhook payloads are verified with HMAC-SHA256 signatures.
What's the minimum contract term?
No long-term contracts. We deliver on monthly engagement with a 30-day notice period.
