Features
Everything US teams need to invoice professionally
All the tools for US small-business invoicing, payment follow-up, customers, e-commerce workflows, and sales-tax review.
Invoices & quotes
Create invoices, proforma invoices, advance invoices, credit notes, and delivery notes in less than 30 seconds. Every document includes a live preview, customizable templates, and automatic numbering.
Client management
Auto-fill client details — tax numbers, addresses, and company names — from the business registry. Less typing, fewer errors.
Payments & receivables
See who owes you money and when payments are due. Automatic reminders chase late invoices for you.
Recurring invoices
Set it up once and get paid on autopilot. Choose the client, line items, and frequency, and Apollo creates and sends each invoice on schedule.
Inventory
Build your product and service catalog once. When you invoice, just pick items and prices, units, and tax rates fill in automatically.
Email & delivery
Send documents by email, track delivery workflows, and connect invoicing to your own systems with API and webhook automation.
Also included
Smaller details that still matter
Document templates
Choose from professional templates. Customize colors, logo, and layout to match your brand.
PDF export & sending
Download invoices as PDFs or email them straight from Apollo, with a personal message for each client.
Multiple companies
Manage several companies from one account and switch between them in one click.
Units / Brands
Run several brands under one company, each with its own branding, address, payment account, and document defaults.
Sales-tax helper
ZIP-code sales-tax estimate lookup for US entities, reusable manual tax rates, and support for layered state, county, city, and special tax lines. Estimates are helper data, not automated tax compliance.
Invoice faster without losing tax review control
Apollo gives US small businesses one place for invoices, customers, reminders, e-commerce workflows, and sales-tax estimate helpers.
