Modern businesses run faster and safer when the core apps are integrated, event-driven, and centrally governed. These integrations reduce manual work, prevent data discrepancies, and unlock real-time automation across the customer lifecycle and back office.
Customer and revenue
- CRM ↔ Billing and payments
- Sync quotes, contracts, products, discounts, and payment methods from CRM to billing; push invoices, payments, credits, and refunds back to CRM for revenue visibility and collections. Verify native APIs/webhooks, payment gateway, tax engine, and proration support.
- Product usage ↔ CRM
- Feed feature usage, seats, and health scores to CRM for PQLs, renewal forecasting, and expansion plays; usage telemetry also informs pricing strategy. Use event webhooks for freshness.
- Billing ↔ Accounting/ERP and rev‑rec
- Post invoices and payments to accounting, sync AR/AP, and automate ASC 606 revenue recognition for subscriptions/usage to stay audit-ready.
Support and success
- Helpdesk ↔ CRM
- Create a unified customer view by syncing contacts, SLAs, entitlements, and ticket context; route high-value or at-risk accounts to success automatically.
- Status/incidents ↔ Helpdesk/Chat
- Push incidents and maintenance windows to support channels and status pages to reduce ticket spikes and improve trust.
Marketing and data
- CDP/Marketing automation ↔ CRM and product events
- Orchestrate lifecycle journeys using real-time events (signup, activation, feature usage) with clean IDs; enforce consent and preference sync.
- Data warehouse/ELT
- Centralize SaaS data via ELT connectors into a warehouse for analytics and ML; adopt schema evolution, lineage, and error retries for reliability.
- BI and dashboards
- Pipe modeled data to BI for ARR/MRR, NRR, funnel, and cohort reporting; schedule alerts to Slack/Email on anomalies.
Identity and security
- SSO/MFA/SCIM across apps
- Standardize authentication with SAML/OIDC and automate user provisioning with SCIM; enforce MFA and device trust for zero‑trust posture. Prefer providers with strong protocol support and audit logs.
- SIEM and audit logs
- Stream auth, billing, and data-access logs to SIEM for detection and compliance; monitor API usage anomalies.
Operations and IT
- HRIS ↔ IT provisioning
- Automate joiner‑mover‑leaver flows across SaaS tools with role-based access via iPaaS or IDP workflows to cut manual IT tickets and reduce risk.
- iPaaS and event orchestration
- Use an AI-enabled iPaaS to manage API workflows, retries, transformations, and event-driven automations across hybrid/multicloud footprints with centralized governance.
Payments, tax, and compliance
- Payment gateways and fraud
- Integrate multiple rails with smart retries and network tokens; add fraud/risk signals for chargeback reduction in self-serve flows.
- Tax and invoicing
- Connect tax engines for VAT/GST/US sales tax; ensure location-based rates and evidence capture sync through billing and accounting.
Integration design checklist
- API and webhook readiness
- Confirm REST/GraphQL coverage, webhook events, rate limits, and idempotency; prefer products with mature developer docs and SDKs.
- Data integration approach
- Choose ELT to the warehouse for analytics at scale; use real-time streaming for operational triggers; ensure schema evolution handling and lineage.
- Security and governance
- Enforce OAuth scopes, secrets vaults, RBAC, and audit logging; document data flows and retention for GDPR/CCPA.
- Hybrid and multicloud
- Ensure connectors support on‑prem and multi‑cloud sources if applicable; centralize monitoring in your iPaaS/API platform.
90‑day rollout plan
- Weeks 1–2: Map the backbone
- Inventory systems, define master data (accounts, contacts, products), and prioritize CRM↔Billing, Product↔CRM, and SSO as day‑one integrations.
- Weeks 3–6: Stand up iPaaS + ELT
- Deploy iPaaS for operational workflows and ELT to the warehouse; wire event webhooks for product and billing; implement SCIM/MFA.
- Weeks 7–10: Expand and secure
- Add helpdesk↔CRM, accounting, tax, and SIEM log streaming; set alerting on failures and SLA dashboards.
- Weeks 11–12: Audit and optimize
- Validate rev‑rec, reduce duplicate records, tune API quotas/retries, and publish data lineage and access policies.
Bottom line
In 2025, essential SaaS integrations are API‑first, event‑driven, and centrally governed: connect CRM, product, billing, accounting, support, identity, and data platforms with iPaaS and ELT to eliminate manual work, improve forecasting, and strengthen security—without brittle glue code.
