What software automates invoice delivery and collections follow-up?

Several categories of software can automate **invoice delivery** and **collections follow‑up** (payment reminders, dunning, etc.). The best choice depends on whether you want simple invoicing, full accounts receivable (AR), or broader AP/AR automation.

### 1. AR-focused platforms (invoicing + collections workflows)

These tools are built specifically to automate sending invoices and chasing payments:

- **Billtrust** – Automates invoice **generation, multi‑channel delivery, tracking, and payment processes**, as part of a unified AR platform that also includes **Collections**.[3] It supports automatic e‑invoice delivery to email, AP portals, EDI, buyer portals, and tracks status in one place.[3]

- **HighRadius** – Offers **Automated Invoice Collection Software** that aims to reduce past‑due invoices with **AI‑driven collections**, including automated outreach and uploading invoices across multiple AP portals.[8]

- **Resolve** – Focused on B2B net terms; provides “**hands‑off invoicing, billings, and collections**” as part of its credit and AR automation solution.[2]

These are best if you need enterprise‑grade AR, multi‑channel delivery, and structured collections workflows.

### 2. Online invoicing & small‑business accounting tools

These tools automate invoice sending and follow‑up reminders directly from your accounting or billing system:

- **QuickBooks, Xero, FreeAgent, ClearBooks, KashFlow, Salesforce (with GoCardless)** – Popular accounting/online invoicing systems that automate invoice creation, delivery, tracking, and reminders for overdue invoices.[1] Xero, for example, provides **automatic reminders and online payment facilities**; QuickBooks tracks overdue invoices “to make chasing payments easier.”[1]

- **Square Invoices** – Free invoicing tool that lets you **send digital invoices via email/SMS**, track status in real time, and **automate billing with recurring invoices and auto‑reminders for upcoming or late payments**, helping reduce overdue invoices.[6]

- **invoicely** – Online invoicing with **recurring invoices** and **automatic payment reminders** to secure cash flow.[7]

Use these if you want straightforward invoice delivery and automated reminders inside a familiar small‑business platform.

### 3. Vertical or practice‑specific tools (invoicing + automated follow‑up)

- **MyCase (for law firms)** – Legal invoicing platform that automates invoice creation, batch billing, and **built‑in automated invoice reminders** so the system “automatically nudges clients when a payment is due,” handling follow‑ups from “creation to collection.”[5]

These are ideal if you’re in a specific vertical (like legal) and want billing plus collections follow‑up tailored to that industry.

### 4. AP / invoice processing automation (if you meant incoming invoices)

If you were asking about automating receipt and approval of **incoming** invoices (accounts payable), these products focus more on capture and approval than collections:

- **Quadient AP Automation** – Automates AP invoice capture, data extraction, approval workflows, export to ERP, and archiving.[4]

- **Yooz, Stampli, DocuWare, MineralTree** – AP automation tools that handle invoice capture, approval, and payment processing rather than AR collections.[2][9]

### How to narrow down

To choose among these, clarify:

- Do you need **outgoing AR** (send invoices + collect payments), **incoming AP** processing, or both?

- Scale: **small business** (Square, Xero, QuickBooks, invoicely) vs **mid‑market/enterprise AR** (Billtrust, HighRadius, Resolve).

- Industry needs: e.g., **legal** (MyCase) or generic.

- Channels: Do you need **AP portal delivery / EDI / Peppol** (Billtrust, HighRadius), or just email/SMS links (Square, Xero, invoicely)?

If you tell me your company size, tech stack, and whether you mostly invoice consumers or B2B customers, I can recommend a short, specific list that fits your use case.
