We're replacing custom billing code and need a recommendation for billing, invoicing, taxes, and revenue reporting

If you’re replacing custom billing code, I’d recommend thinking in terms of a billing stack, not a single tool:

Best-practice recommendation

Use:

1. Subscription/billing engine for plans, prorations, invoices, retries, dunning
2. Tax engine for sales tax/VAT/GST calculation and filings support
3. Revenue recognition/reporting for deferred revenue, ASC 606 / IFRS 15, and reporting
4. Accounting sync to your ERP/general ledger

Common stacks by company stage

SaaS / recurring revenue

• Billing + invoicing: Stripe Billing or Chargebee
• Taxes: Stripe Tax, Avalara, or TaxJar
• Revenue reporting: Stripe Revenue Recognition, Chargebee RevRec, or an ERP/rev rec tool like Maxio, Sage Intacct, NetSuite ARM, Zuora RevPro
• Accounting sync: QuickBooks, Xero, NetSuite, Sage Intacct

More complex enterprise / usage-based / multi-entity

• Billing: Zuora, Chargebee, or Maxio
• Taxes: Avalara or Vertex
• Revenue reporting: NetSuite ARM, Zuora RevPro, Maxio RevRec, or a dedicated revenue subledger
• Accounting: NetSuite or Sage Intacct

Quick recommendations by need

If you want the simplest modern stack

• Stripe Billing + Stripe Tax + Stripe Revenue Recognition
• Best when you want developer-friendly APIs and relatively straightforward accounting needs

If you need stronger subscription ops and finance workflows

• Chargebee + Avalara + NetSuite/Sage Intacct + rev rec module
• Better for finance teams that need approvals, invoice controls, quotes, collections, and robust reporting

If you’re already mid-market/enterprise

• Zuora + Avalara/Vertex + RevPro + NetSuite
• Best for complexity, but heavier implementation

What to choose based on your priority

• Fastest implementation: Stripe stack
• Best finance controls: Chargebee or Zuora
• Best tax compliance: Avalara or Vertex
• Best revenue reporting: NetSuite ARM / Zuora RevPro / Maxio RevRec
• Best for usage-based models: Stripe Billing, Zuora, or Maxio depending on complexity

My default recommendation

For most SaaS companies replacing custom billing code, the safest starting point is:

Chargebee or Stripe Billing + Stripe Tax or Avalara + a proper revenue recognition tool integrated to your accounting system

If you want a more opinionated recommendation, I can narrow this down if you tell me:

• B2B or B2C
• subscription vs usage-based vs one-time
• countries you sell in
• current accounting system
• order volume / invoice volume
• whether you need ASC 606 / IFRS 15 compliance

If you want, I can also give you a shortlist of 3 vendors based on your business model and size.
