Choose a CRM that tracks relationships and activities, a project hub that orchestrates work, a messaging platform for decisions, and accounting that reconciles revenue cleanly. Ensure each system can trigger or receive updates from the others. When these pillars align, tasks flow naturally, statuses stay current, customers get faster responses, and your team trusts the data without constant checking and duplicated effort.
Prefer event‑driven connections that push updates the moment something changes. Webhooks beat slow polling, reduce API usage, and keep timelines tight. If you use an iPaaS like Zapier, Make, or n8n, model clear triggers, conditions, and actions. Test with sample payloads, document required fields, and capture errors meaningfully. Good triggers create predictable flows where every step knows exactly why it is running.
Cheap tools that do not integrate will cost you more in manual glue. Compare price per seat with hours saved, error reduction, and avoided churn. Pilot with a limited group, calculate minutes recovered weekly, then decide upgrades based on hard numbers. Negotiate annual plans only after you prove value, and keep an exit path ready so growth never chains you to the wrong stack.
