Attio integrations_

Attio integrates with Gmail, Outlook, Slack, Zapier, and a growing number of tools through its native integration library and a comprehensive modern REST API with webhooks. As the CRM built for relationship-driven businesses, Attio is adopted by advisory firms, investment managers, consultancies, and professional services businesses that value relationship intelligence over traditional pipeline management. Native integrations cover email sync and basic notifications. For deal-to-delivery workflows that connect Attio’s relationship data to accounting, project management, and operational tools from a single trigger, Formulaic builds custom Attio integrations with no marketplace limits.

Short answer: Attio has native integrations with Gmail, Outlook, Slack, and Zapier. Formulaic builds custom integrations that connect Attio’s relationship intelligence to Xero, project tools, and reporting systems — orchestrating 5+ tools from one trigger and replacing SaaS subscriptions with systems you own.

What we build that native integrations can’t

Attio’s native integration approach reflects its design philosophy: a small number of deep integrations rather than a marketplace of hundreds. Email sync with Gmail and Outlook automatically enriches contact records. Slack provides notifications. These native connections are focused and well-built.

Where Attio’s native library is still growing is in operational tool connections. Advisory firms need deal completion to trigger accounting entries in Xero, project setup in their delivery tool, client onboarding sequences, and reporting updates. They need relationship data flowing to management dashboards. They need client health scores informing team notifications. These workflows span systems that Attio’s current native library does not reach. We build it.

A boutique advisory firm managing 30 active client relationships needs Attio’s relationship intelligence connected to Xero for invoicing, a project tool for engagement tracking, Slack for team coordination, and Excel for partner-level reporting. That’s not “Attio to Xero.” That’s a relationship-driven practice system.

Multi-tool orchestration

The firms we work with don’t need “Attio to X.” They need “when a relationship reaches a milestone, everything downstream handles itself.”

Examples of what a single custom integration handles:

• Deal closed → Xero invoice created with service-specific codes, project created with correct template, delivery team notified in Slack, client onboarding sequence triggered, relationship record updated with engagement timeline
• Relationship health changes → low-engagement clients flagged, partner notified, re-engagement sequence triggered, CRM task created for relationship review
• New contact added → enriched from public data and interaction history, scored against ICP criteria, routed to correct pipeline, relationship strength calculated from email frequency and meeting history
• Quarterly review triggered → relationship data extracted, revenue per relationship calculated, client health scores aggregated, management report pushed to Excel dashboard

Each of these replaces manual relationship management work that advisory firms do daily. At 30+ active relationships, the automation compounds.

Replace SaaS, don’t just integrate it

Attio firms tend to value quality over quantity in their tool stack. But most still run separate tools for accounting, project management, and reporting that could be consolidated.

We’ve seen firms paying for a standalone client reporting tool, a separate project tracker, and a third-party pipeline dashboard — when a single custom system connected to Attio handles all three. Built for relationship-driven workflows, owned by them, with no per-seat licensing.

Attio’s API quality makes custom alternatives particularly cost-effective to build. We start with the audit: map your current stack, identify what’s redundant, and propose what to build vs what to keep.

How we approach Attio integrations

1. Audit your stack — we map every tool connected to Attio, how relationship data flows between systems, where the manual steps live, and what’s costing you the most time or money. Two weeks.

2. Design the system — not “which tools to connect” but “what should happen when a relationship reaches a milestone.” We design around your advisory workflow, not around tool limitations. The output is a build spec with clear scope.

3. Build and deploy — direct API integration with Attio. No middleware, no Zapier, no per-task fees. The system connects to your accounting, delivery, and communication tools with full error handling and monitoring. You own the source code.

No marketplace limits

We don’t need official connectors or pre-built integrations. Attio’s API covers records, lists, attributes, notes, tasks, and workspace data comprehensively. We connect Attio to any tool — Xero, QuickBooks, project management platforms, email sequence tools, and internal systems your firm has used for years.

Compliance across jurisdictions

Every custom Attio integration we build accounts for the regulatory environment your firm operates in. For UK firms: FCA requirements where advisory services touch regulated advice, anti-money laundering checks for client onboarding, UK GDPR data handling for relationship and prospect data, and data residency requirements. For US firms: SEC and state-level requirements for financial advisory, and data protection standards. For Australian firms: ASIC requirements and data sovereignty. For Canadian firms: provincial regulatory requirements.

Relationship data carries compliance weight. Prospect enrichment, interaction logging, and client data synchronisation all have data handling, consent, and audit trail requirements baked into the integration architecture.
