Vertex Alternatives: 6 Tax Engines Compared (2026)
6 Vertex tax alternatives for 2026: Avalara, ONESOURCE and Sovos for enterprises, and GoodVat, Anrok and Stripe Tax if Vertex is more than you need.
Quick answer: if you’re replacing Vertex with another enterprise engine, look at Avalara, Thomson Reuters ONESOURCE and Sovos. If Vertex is more than your business needs, look at GoodVat (free to start, sales tax, VAT and GST in 140+ countries), Anrok (B2B SaaS) and Stripe Tax (Stripe-only businesses).
Vertex is one of the oldest names in indirect tax (founded 1978, listed on Nasdaq as VERX), built to run inside SAP, Oracle and other ERPs. People look for an alternative for one of two reasons: they want a different enterprise engine, or they’ve realised they don’t need one. This guide covers both. Facts were checked on 12 November 2026.
Disclosure: GoodVat publishes this comparison and is one of the tools on it. Enterprise vendors don’t publish prices, so we don’t guess them.

What’s new at Vertex
- E-invoicing push. Vertex bought ecosio (Peppol and EDI) in August 2024 and Brinta, a Latin American e-invoicing start-up, in March 2026.
- Big contracts. Vertex reported average annual revenue of about $143,000 per direct customer in Q2 2026, up 9% on the year.
- Modules. Calculation, returns, exemption certificates and e-invoicing are still sold separately, on quotes.
Two reasons to leave Vertex
| You’re leaving because… | Your shortlist |
|---|---|
| You want a different enterprise engine (price at renewal, ERP migration, e-invoicing coverage) | Avalara, ONESOURCE, Sovos |
| Vertex is more than you need (no ERP project, no tax team, mostly online sales) | GoodVat, Anrok, Stripe Tax |
Enterprise alternatives
1. Avalara
- Best for: mid-market and enterprise businesses that want more prebuilt connectors and exemption certificate management
- Price: Avalara Select, published in August 2026, is $69 to $79 per state per month for businesses under $50 million in revenue; above that, quoted
- Compare: Avalara vs Vertex
Avalara is the closest like-for-like swap. It’s broader on integrations (1,400+ on custom plans) and easier for mid-sized businesses to buy now its US prices are public. Vertex tends to be preferred inside very large SAP deployments.
2. Thomson Reuters ONESOURCE
- Best for: enterprises that want indirect tax, corporate tax and e-invoicing from one vendor
- Price: quote
- E-invoicing: through Pagero, which Thomson Reuters acquired in 2024
ONESOURCE is often reported as the priciest of the three enterprise options, because it’s sold as a wider tax suite, and implementations take time.
3. Sovos
- Best for: multinationals facing real-time e-invoicing and clearance mandates in Latin America and Europe
- Price: quote
- E-invoicing: its core strength; Sovos is an approved e-invoicing platform (PA) in France
Sovos is the pick when e-invoicing, not sales tax calculation, is the hard problem.
Alternatives if Vertex is more than you need
4. GoodVat
- Best for: online businesses selling across stores, marketplaces and payment processors, plus marketplaces and payment processors that want tax under their own brand
- Price: free to start, then $20, $50 or $100 a month by transaction volume, with every jurisdiction and feature on every plan
- Coverage: sales tax, VAT and GST in 140+ countries and 14,000+ US jurisdictions; e-invoicing (EN 16931, Peppol, France, Spain’s Verifactu and SII) included
- Filing: ready-to-file returns on every plan, or our local accountants handle registration, deregistration and filing (filing prices)
- Compare: GoodVat vs Vertex
Set up with you by our team in days, with no ERP project. It connects to NetSuite, Sage, QuickBooks, Xero and Zoho Books, but not SAP or Oracle, so it isn’t a fit if those run your tax.
5. Anrok
- Best for: B2B SaaS companies billing through Stripe Billing, Chargebee or similar
- Price: from $100 per market per month; most plans are custom
- Compare: Anrok vs Vertex
6. Stripe Tax
- Best for: businesses that take every payment through Stripe
- Price: 0.5% per transaction; filing costs extra, $90 to $1,500 a month on a one-year plan, with returns filed through Taxually (TaxJar in the US)
- Compare: Stripe Tax vs Vertex
When to stay with Vertex
Stay if Vertex already runs inside your SAP or Oracle system, your tax team has built its rules there, and your issue is price rather than fit. Switching an enterprise tax engine is an ERP project in itself, so negotiate at renewal before you migrate.
How to choose

| B2B SaaS with a finance team | Anrok |
