Xero at the coreOne source of financial truth, everything feeds it

The foundation

Built on the Xero ecosystem.

As a two-time Advisory Innovator of the Year, Xero's 2026 AI Efficiency Champion, and featured with Xero on CBS 50 American Leaders, we have spent years inside the Xero ecosystem. We configure Xero as the financial hub of your startup, then connect everything else to it.

Every startup's tech stack is different, but the need for a single source of financial truth is universal. MATAX uses the full range of the Xero platform, from native marketplace apps to custom API integrations, so every transaction, invoice, and payment flows into your books automatically. Whether you run a SaaS company with recurring billing, an ecommerce business with multi-channel sales, or a fintech startup processing thousands of daily transactions, we design an integration architecture that handles your complexity without manual intervention.

  • Xero setup, migration, and optimization
  • 1,000+ native Xero app marketplace integrations
  • Custom API connections for non-standard tools
  • Bank feeds, payment processors, and payroll
  • Real-time dashboards and reporting

The insights needed to grow

Automation and productivity

Where disconnected tools become one system.

We use Make, Zapier, and n8n to build workflows that move data between your apps automatically, triggered by events, scheduled runs, or AI-powered logic. From invoice creation to lead routing to inventory updates, we automate the repetitive tasks that slow your team down.

Integrations

Tools we connect.

These are the tools we integrate most often for startups. With over 200 integrations in our portfolio and the ability to build custom API connections, MATAX can connect virtually any tool in your stack.

Accounting and finance

Financial data is the backbone of your startup's operations. We connect your payment processors, banking platforms, and payroll systems directly to Xero so every dollar is tracked automatically. No manual reconciliation, no mismatched records, just accurate financial data flowing in real time.

Ecommerce and project management

For ecommerce startups, connecting your storefront to your accounting and inventory systems is critical. We integrate Shopify and Amazon so orders, refunds, fees, and inventory changes sync automatically with Xero. Project management tools like Asana, Monday, and Notion connect to your time tracking and billing so billable hours and project costs are captured without manual effort.

CRM and communication

Your sales pipeline, customer communications, and team collaboration tools generate data that should flow into your financial and operational systems. We integrate CRMs like HubSpot with your accounting stack so deals generate invoices, customer onboarding triggers workflow automations, and your team stays informed through real-time Slack notifications.

How it works

From disconnected to unified.

We start by understanding your current stack, then systematically build the connections and automations that turn isolated tools into a cohesive operating system for your startup.

01

Stack audit

We map every tool your team uses and identify overlaps, gaps, and integration opportunities. That includes documenting current data flows, manual processes, and pain points, so we can design the most useful integration architecture rather than the most obvious one.

Week 1
02

Connect and configure

We build the integrations, set up data flows, and configure automations between your tools. Every connection is tested end to end with your real data for accuracy, reliability, and proper error handling before going live.

Weeks 2 to 3
03

Monitor and optimize

Ongoing monitoring, error handling, and optimization as your stack evolves. We identify issues proactively, add new integrations as you adopt new tools, and improve your workflows based on real usage data.

Questions

Integration FAQs.

What founders ask before connecting a stack.

MATAX integrates 200+ apps across accounting, CRM, ecommerce, project management, communication, payment processing, and payroll. The most common are Xero, Shopify, HubSpot, Slack, Make, Zapier, Stripe, PayPal, Gusto, Amazon, Asana, Monday, Notion, Gmail, Outlook, and Calendly. If your tool has an API, or connects to a platform like Make or Zapier, we can almost certainly integrate it.
Yes. If you use proprietary software, industry-specific platforms, or tools without native integrations, we build custom API connections and middleware to bridge the gap. We use Make and n8n for advanced automation, and where needed we develop bespoke integrations that connect your tools directly to Xero and the rest of your stack.
Most integration projects are live within 2 to 3 weeks. Week 1 is a stack audit where we map your tools, data flows, and pain points. Weeks 2 and 3 are building, configuring, and testing end to end with your real data. Projects involving several custom API connections or a large data migration can run 4 to 6 weeks. After launch we monitor and optimize on an ongoing basis.
Book a free stack review. It is a 30-minute conversation, not a pitch: we walk through the tools you use today, where the manual work is, and how those tools could fit together. No commitment, and nothing to prepare. If it makes sense to go further, a written integration plan comes after that as part of a scoped engagement.
