Vertex vs Taxually for Cross-Border Sellers 2026

Vertex and Taxually are not natural competitors — they operate at different layers of the tax compliance stack and, for many businesses, work best used together. Vertex is an enterprise real-time tax calculation engine, embedded in SAP, Oracle, and complex ERP environments. Taxually is an EU/UK VAT compliance and filing specialist — a licensed intermediary that takes your sales data and handles the regulatory submission.

The key distinction: Vertex determines the tax due on every transaction at the point of sale. Taxually takes that (and other) transaction data and files the returns with tax authorities. If you already have Vertex or another enterprise calculation tool and just need someone to file your IOSS, OSS, and UK MTD returns, Taxually fills that gap cleanly.

1. Local VAT / Sales Tax Filing

Section titled “1. Local VAT / Sales Tax Filing”

Vertex: Full UK MTD filing capability via Vertex Cloud VAT Returns. Vertex calculates UK VAT across all connected systems, generates MTD-compliant submissions, and can file directly with HMRC. Handles multi-entity UK structures, VAT group returns, and complex partial exemption scenarios.

Taxually: Acts as a licensed UK VAT agent and files MTD returns on your behalf. Taxually pulls sales data from connected channels — Shopify, Amazon, WooCommerce, Stripe, and others — prepares the VAT return, and handles HMRC submission directly. For businesses that want to fully outsource UK VAT filing to a compliance specialist rather than a software platform, Taxually’s service-led approach is the distinction.

Verdict: Both provide UK MTD filing capability. Vertex embeds filing into an enterprise ERP workflow; Taxually provides it as a managed service. For businesses that want a dedicated compliance team handling their returns rather than configuring software, Taxually is the more appropriate model.

2. EU IOSS

Section titled “2. EU IOSS”

Vertex: Supports IOSS calculation across all connected platforms and ERP systems. Correctly applies destination-country VAT rates to EU shipments under €150 and zero-rates shipments above the threshold. Vertex is not an IOSS intermediary — it does not hold a registration in an EU member state or file the monthly IOSS return with EU tax authorities. A separate intermediary is required.

Taxually: Acts as a registered IOSS intermediary — this is a legal role, not just a software feature. Taxually holds IOSS registration on your behalf in an EU member state, aggregates your sales data from all connected channels, prepares the monthly IOSS return, and submits it to the relevant tax authority. Taxually takes on the regulatory obligation, not just the calculation.

The practical difference: if you use Vertex for calculation and need IOSS filing covered, Taxually can sit alongside it. Vertex calculates the correct amount; Taxually reports and remits it.

Verdict: Taxually wins on IOSS filing — that’s its core product. Vertex calculates; Taxually files. For businesses that already have Vertex for calculation, adding Taxually specifically for IOSS filing is a logical combination.

3. EU OSS

Section titled “3. EU OSS”

Vertex: Full OSS calculation across Union and Non-Union schemes. Country-level reports produced. Managed filing available via Vertex’s partner network. Strong for enterprises with multi-country EU registrations and complex intra-EU supply chains.

Taxually: Specialises in OSS filing management. Taxually handles OSS registration in the relevant EU member state, aggregates quarterly sales data across all connected channels, prepares the return, and submits. For UK businesses selling digital services to EU consumers under Non-Union OSS — one of the most common compliance scenarios for online sellers — Taxually is a purpose-built solution.

Verdict: Taxually wins on OSS filing accessibility and service-led compliance. Vertex handles OSS in a broader enterprise context but requires implementation resources to configure. For a UK seller who simply wants OSS taken off their plate, Taxually is significantly more accessible.

4. US Sales Tax

Section titled “4. US Sales Tax”

Vertex: Deep and comprehensive. US sales and use tax is Vertex’s founding purpose — the platform covers all states, complex product taxability, exemption certificates, purchase-side use tax, and SST filing. For enterprises with multi-state US sales across complex product catalogues, Vertex’s US capability is the strongest in the industry.

Taxually: No US sales tax support. Taxually’s product is entirely focused on EU and UK VAT regimes. If you have US sales tax obligations, Taxually cannot help — you need a separate tool.

Verdict: Vertex wins completely. Taxually does not compete here. For UK sellers with US sales tax obligations alongside EU VAT filing needs, a two-tool approach is necessary — something like Vertex or Stripe Tax for US sales tax, and Taxually for EU/UK filing.

5. VAT Calculation at Checkout

Section titled “5. VAT Calculation at Checkout”

Vertex: Real-time calculation at the point of transaction across all connected systems. Handles B2B reverse charge, EU VAT ID validation, and complex product taxability in real time. Designed for high transaction volumes and multi-channel enterprise architectures.

Taxually: Does not calculate VAT at checkout. Taxually is an after-the-fact compliance tool — it aggregates transaction data that has already been collected to prepare and submit tax returns. If you don’t already have a checkout calculation tool, Taxually cannot replace one. It’s explicitly designed to complement tools like Stripe Tax, Shopify Tax, or Vertex — not to replace them at the calculation layer.

Verdict: Vertex wins. This is a fundamental capability gap for Taxually — it does not sit in the checkout flow at all. If you use Taxually, you must have a separate checkout calculation tool working alongside it.

6. Platform Integrations

Section titled “6. Platform Integrations”

Vertex:

  • SAP — Gold Partner; deepest SAP integration in the industry
  • Oracle — native connectors for major Oracle products
  • Microsoft Dynamics 365 — native connector
  • NetSuite, Salesforce — connectors available
  • Shopify, BigCommerce, Magento — connectors available
  • Custom APIs — Vertex O Series API for bespoke integrations

Taxually:

  • Shopify — native app for data collection and return preparation
  • WooCommerce — native plugin
  • Amazon, eBay, Etsy — marketplace integrations for data aggregation
  • Stripe — integration for payment data import
  • Xero, QuickBooks — accounting integrations for data import

Taxually’s integrations are designed to pull historical sales data for compliance use — not to sit in the live checkout flow. Its integration map reflects its buyer profile: SMB and mid-market sellers on e-commerce and marketplace platforms who need someone to handle their filing.

Verdict: Different integration purposes. Vertex integrates at the transaction calculation layer into enterprise systems. Taxually integrates at the data aggregation layer into e-commerce and accounting platforms for filing. They’re complementary, not competing, in this dimension.

7. Pricing Model

Section titled “7. Pricing Model”

Vertex: Quote-based. Enterprise pricing typically starting at $30,000–$100,000+/year, excluding implementation costs. Vertex is not accessible for SMBs or most mid-market businesses.

Taxually: Subscription-based, starting at approximately €49–€99/month depending on the services required (IOSS intermediary, OSS filing, UK MTD, local EU VAT registrations) and transaction volume. Transparent, accessible pricing for the services it provides.

Verdict: Taxually is dramatically more affordable for EU/UK compliance filing specifically. Vertex’s pricing reflects a completely different product scope. For a UK seller who just needs IOSS intermediary services and OSS filing, Taxually is all you need — and costs a fraction of what Vertex does.

8. Setup Complexity

Section titled “8. Setup Complexity”

Vertex: Very high. Enterprise implementation project. Certified implementation partner required. Months of scoping, configuration, and testing. Not an option for businesses without dedicated IT and tax technology resources.

Taxually: Low to moderate. Connecting your sales channels and completing VAT/IOSS/OSS registrations is guided by Taxually’s compliance team. For most UK sellers, the onboarding process takes days to weeks — not months.

Verdict: Taxually is dramatically easier to deploy for its specific use case. Vertex’s complexity is the cost of its depth. For a seller who needs EU/UK filing compliance sorted quickly, Taxually is the practical choice.

9. Reporting and Records

Section titled “9. Reporting and Records”

Vertex: Enterprise-grade audit trails, transaction-level records, rate history, jurisdiction summaries, and a tax data warehouse for analytics. Comprehensive for multi-country, multi-entity audits.

Taxually: Retains the authoritative compliance archive for the returns it files. Because Taxually legally files your returns, it holds the submitted return records, tax authority receipts, and the 10-year transaction archive required under EU IOSS rules. In the event of an EU VAT audit, Taxually provides the documentation trail for the returns it submitted.

Verdict: Both produce audit-grade records, but for different purposes. Vertex’s records cover the full transaction calculation history. Taxually’s records cover the submitted returns and regulatory correspondence. For EU IOSS specifically, Taxually’s return-level archive is exactly what an audit requires.

10. Ecosystem / Wider Product

Section titled “10. Ecosystem / Wider Product”

Vertex:

Vertex covers the full enterprise indirect tax function: US sales and use tax, global VAT and GST, e-invoicing (EU ViDA), cross-border trade and HS classification, property tax, and purchase-side use tax. For large enterprises, Vertex is the backbone of the indirect tax function — not just a filing service.

Taxually:

Taxually’s product scope is focused on EU and UK VAT compliance as a managed service: IOSS intermediary registration and filing, EU OSS filing, UK MTD filing, and local EU VAT registrations in individual member states where sellers hold stock (e.g., Amazon FBA fulfilment centres). Taxually’s compliance team is experienced with EU VAT authorities and handles queries and correspondence on behalf of clients.

Notably, Taxually is featured as a recommended partner directly within the Stripe Tax Dashboard — Stripe surfaces Taxually to Stripe Tax users who need an IOSS intermediary alongside their checkout calculation. This embedded partnership is an indicator of how Taxually positions itself: as the filing layer that calculation tools like Stripe Tax and Shopify Tax don’t provide.

Verdict: Vertex is a broad enterprise platform. Taxually is a focused EU/UK compliance service. For large enterprises, Vertex covers the whole function. For SMBs and mid-market sellers, Taxually covers the specific gap that calculation tools leave open.

11. Support

Section titled “11. Support”

Vertex: Tiered enterprise support with account management at higher contract levels. Vertex University for training and certification. Deep product expertise from implementation partners.

Taxually: Human compliance support staffed by VAT specialists. Taxually’s team handles EU VAT registrations, responds to tax authority queries, and advises on compliance requirements across EU member states. For sellers navigating IOSS intermediary obligations, OSS registration, and multi-country local registrations, this domain expertise is practical and immediately useful.

Verdict: Taxually wins on EU VAT compliance domain expertise and accessibility. Vertex’s support is enterprise-grade but is more IT and product-focused than regulatory-focused.

12. Best For — The Honest Verdict

Section titled “12. Best For — The Honest Verdict”

Choose Vertex if:

  • You’re an enterprise with SAP, Oracle, or a complex ERP and need real-time tax calculation embedded at the transaction level
  • US sales tax is a significant obligation — particularly purchase-side use tax for manufacturers and distributors
  • You need a single platform covering the full indirect tax function across all business units
  • Your EU/UK filing can be handled within Vertex’s managed services framework rather than as a standalone service

Choose Taxually if:

  • You already have a checkout calculation tool (Stripe Tax, Shopify Tax, or similar) and need someone to file your EU/UK returns
  • You need a registered IOSS intermediary to handle your monthly IOSS obligations legally
  • You want EU OSS and UK MTD compliance outsourced to a specialist without enterprise software costs
  • You sell on Shopify, WooCommerce, Amazon, or eBay and need a filing partner that connects to those channels

Use both if:

  • You’re a large enterprise running Vertex for calculation and need Taxually’s IOSS intermediary and OSS filing services on top — the two tools address complementary layers of the compliance stack
