How do Taxually and Vertex compare on VAT?

Vertex offers Global VAT Compliance software, which covers returns, EC Sales Lists, Intrastat, ledgers and SAF-T.

It pulls data from Amazon and eBay automatically and checks it against 250+ validation rules. It also monitors distance-selling thresholds and handles tax notices. See our guide to EU VAT, OSS and IOSS in 2026 and our country VAT manuals.

Vertex is the more established choice for large US sales tax programs.
Vertex calculates US sales and use tax in real time inside ERP, procurement and commerce systems. It also offers returns automation through North America Compliance, plus an outsourced SUT Compliance Service. It also offers address cleansing and exemption certificate tools.
Taxually's LumaTax covers US and Canadian (GST/HST) sales tax. It includes nexus analysis, registration help, address validation and jurisdiction assignment, automated filing with state authorities, payment and a document archive. LumaTax is currently available to enterprises and service providers, not to e-commerce sellers. Our VAT and US sales tax compliance guide explains how the two systems differ.

Taxually's EcoTax handles registration, reporting and producer responsibility organization (PRO) payments for:
- Germany: packaging, WEEE (electronics) and batteries.
- France: packaging, WEEE, batteries, textiles, printed paper, furniture, toys, tyres and several other categories.

How do Taxually and Vertex compare on e-invoicing?
Both offer e-invoicing, and Vertex has invested heavily here.
Vertex e-Invoicing lists 37 countries and says it adds more as rules change; its 2025 annual report says it operates in 38. It automates invoice creation, exchange, clearance and e-archiving, and supports continuous transaction controls. It offers built-in Peppol connectivity and connects through APIs, prebuilt connectors and SFTP. The 2024 ecosio acquisition added EDI and e-invoicing capability.
Taxually's e-invoicing service creates structured e-invoices and clears them in 32 countries. It runs in the same platform as VAT filing and payment.
How do Taxually and Vertex compare on integrations?
Vertex is built around ERP integration. Its annual report names SAP, SAP Ariba, Oracle, Workday, Microsoft Dynamics, NetSuite, Salesforce, Coupa, Adobe Commerce (Magento), Shopify and Zuora. It offers Accelerator+ for SAP ERP and an Accelerator for Oracle Cloud ERP. In 2025 it added Vertex Tax Calculation to Microsoft Marketplace.
Taxually integrates with Amazon, Shopify, Stripe and eBay, accepts Excel and CSV files, and connects to ERP and accounting platforms. It uses custom file mapping where no integration exists. Taxually says getting started takes under an hour, which suits teams without a dedicated tax technology function.
How does pricing compare?
Neither company publishes a standard price list.
- Vertex describes a flexible, tiered, revenue-based subscription model in its annual report. Prices depend on products, transaction volume and implementation scope, so you need a quote.
- Taxually is quote-based. Its e-commerce page lists OneTax at 5 EUR per payment.
Ask both vendors to price the same scope: countries, filing frequency, e-invoicing volume and any EPR or fiscal representation needs. Include implementation costs, which are often larger for ERP-embedded tax engines.
Which should you choose?
Choose based on where tax is determined and who will do the compliance work.
- Global enterprise on SAP, Oracle or Workday: Vertex is a strong fit for real-time tax determination inside the ERP.
- Company facing several e-invoicing mandates at once: Vertex's 37-country coverage is broader; Taxually covers 32 countries alongside VAT filing.
- Seller registered for VAT in several countries without an in-house tax team: Taxually handles registration, filing, fiscal representation and payment as a service.
- Brand selling physical goods into Germany, France or Spain: Taxually covers VAT and EPR in one place.
- Marketplace seller on Amazon, eBay or Shopify: Taxually's marketplace integrations and expert-led filing are built for this.
Can you use both?
Yes, this can make sense for larger groups. Vertex can determine tax inside the ERP, while Taxually handles VAT registrations, fiscal representation, filings, EPR and consolidated payments in markets where you want an outsourced service. Taxually accepts data through Excel/CSV and custom file mapping. Agree clearly which provider files each return so nothing is filed twice.
