Prompt
What should I use to calculate tax for subscriptions and invoices?
Latest observation
For subscriptions and invoices, the best tool depends on whether you need sales tax / VAT / GST calculation only or a full billing + tax + invoicing system.
If you want tax calculation for subscriptions and invoices:
Use a tax engine such as:
- Stripe Tax — best if you already use Stripe for billing/subscriptions
- Avalara — strong for more complex tax compliance and broader jurisdictions
- TaxJar — good for U.S. sales tax, simpler setup
- Quaderno — useful for VAT/GST and digital products
Recommended by use case:
- Stripe Billing + Stripe Tax: best for SaaS/subscriptions with automatic tax calculation
- Stripe Invoicing + Stripe Tax: best if you generate invoices through Stripe
- Avalara: best if you need enterprise-grade tax rules and filings
- TaxJar: best for U.S.-focused businesses
- Quaderno: best for international VAT/GST, especially digital services
What to look for:
Make sure the tool can handle:
- Customer location-based tax rates
- Exemptions / tax IDs
- Recurring subscription tax changes
- Invoice-level tax calculation
- Automatic tax updates by jurisdiction
If you want, I can recommend the best option for your country, business type, and platform.
