You don't. A well-architected AI agent sits on top of your existing stack — your CRM, scheduling tool, accounting software — and talks to them via their APIs. This guide walks through how that integration actually works. **How Keres AI handles it:** Remi connects to Google Calendar, HubSpot and ServiceTitan today, and to other tools through Zapier; Keres AI sets the connection up for you and lists the rest as rolling out until they are live. ## What "integration" really means Integration means one thing: your AI agent can read from and write to your existing tools. It doesn't replace your CRM; it updates records in your CRM. It doesn't replace your scheduler; it books into it. For a typical field service stack, that usually means: - **CRM / job management.** ServiceTitan, Housecall Pro, Jobber, FieldEdge, or similar. The agent reads customer history and writes new jobs. - **Calendar / dispatch.** Either built into the CRM, or a separate tool like Google Calendar. - **Accounting / invoicing.** QuickBooks, Xero, Sage. An agent can draft invoices and send reminders (Keres AI does not connect to accounting software today). - **Communication.** Twilio, RingCentral, or similar for SMS and voice. ## Integration patterns that work There are three common patterns for connecting AI agents to existing tools, in order of preference: ### Native API integration If your CRM has a documented REST API (most modern ones do), this is the cleanest option. The agent authenticates, calls endpoints directly, and gets structured responses. Real-time, reliable, and auditable. ### Webhook-driven integration When the CRM can push events to your agent (new lead, job updated, invoice paid), the agent can react in real time. Pair this with native API calls back to the CRM for a very clean two-way sync. ### Automation-platform middleware Tools like Zapier, Make, or n8n can sit between your AI agent and legacy systems without proper APIs. Not as fast, and more fragile, but often the only option for older tools. Honest tradeoff If your CRM has no API at all — some older tools genuinely don't — your options narrow. Either upgrade the CRM, use screen-scraping (fragile), or accept that the automation can only live upstream (intake) and not write back. ## Which tools integrate well ServiceTitan, Jobber, Housecall Pro and QuickBooks Online each publish developer documentation for their APIs; check what your plan includes, because API access is not always on the entry tier. Older desktop-only CRMs usually need middleware or a workaround. Where Keres AI stands today: Remi writes jobs into ServiceTitan and books into Google Calendar and HubSpot, and Zapier passes leads to other apps. Jobber, Housecall Pro and FieldEdge are rolling out and are not live yet; the [integrations page](https://www.keresai.com/integrations) lists every tool and its status. ## What can go wrong Common integration failures, and the usual fix for each: - **Permission issues.** Your API token doesn't have write access to the right objects. Fix: work with your CRM admin to scope properly. - **Rate limits.** High-volume integrations can hit API rate limits. Fix: batching and intelligent retry logic. - **Data model drift.** Your CRM evolves. Fields get renamed. The integration breaks silently. Fix: monitoring and schema validation. - **Missing webhooks.** The CRM doesn't emit an event for something you need. Fix: scheduled polling as fallback. ## Security and data residency Before any integration ships, three questions: - **Where does the data live?** If you're in regulated territory (HIPAA, SOC 2 requirements and so on), the answer matters. Keres AI is not SOC 2 or HIPAA certified and does not sign BAAs. - **Who has access to the API credentials?** Scope narrowly. Rotate regularly. Never check them into code. - **What's logged?** Every agent action should be auditable after the fact. "The AI booked this job" needs to be traceable. What to ask us If you're planning a deployment, the first conversation should be about your existing tools, not about the AI. "What do you currently use?" beats "what do you want the AI to do?" every time. ## Where Keres AI fits Keres AI connects today to [Google Calendar](https://www.keresai.com/integrations/google-calendar), [HubSpot](https://www.keresai.com/integrations/hubspot), [ServiceTitan](https://www.keresai.com/integrations/servicetitan) and [Zapier](https://www.keresai.com/integrations/zapier); the rest are listed as rolling out on the [integrations page](https://www.keresai.com/integrations).
