Features
Everything US teams need to invoice professionally
All the tools for US small-business invoicing, payment follow-up, customers, ecommerce 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 from the business registry — tax numbers, addresses, and company names. Save hours of manual data entry and reduce errors.
Payments & Debts
Know exactly who owes you money and when payments are due. Automatic reminders ensure you never have to chase late invoices — Apollo handles it for you.
Recurring Invoices
Set up once, get paid on autopilot. Choose the frequency, client, and line items — Apollo creates and sends invoices automatically on your schedule.
Inventory
Build your product and service catalog once. When invoicing, just pick items — prices, units, and tax rates fill in automatically. No more looking up rates.
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
Export invoices as PDF or send them directly via email. Customize the message for each client.
Multiple Companies
Manage multiple companies from a single account. Switch between companies with one click.
Units / Brands
Run multiple brands or operating units under one legal entity with separate branding, addresses, payment accounts, 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, ecommerce workflows, and sales-tax estimate helpers.
