API Integrations • CRM ↔ ERP • Manufacturing & Wholesale

Make Your CRM and ERP Talk—Securely, Reliably, and with Full Traceability.

I design and deliver integration-ready CRM/ERP architectures that replace manual handoffs, eliminate duplicate data, and keep mission-critical workflows consistent—from quote-to-cash to procurement, inventory, and returns & claims.

  • Versioned API contracts (stable changes, predictable releases)
  • Signed webhooks + idempotent event handling (retries are safe)
  • Observability: logs, metrics, traces, and actionable alerts
  • Documentation included (handover your team can own)

API integrations connecting CRM, ERP, procurement, and inventory with governance and observability

Security-by-default

Auth, RBAC, audit trails, and least privilege.

Versioned contracts

Predictable change management and rollouts.

Observability

Logs, metrics, traces, and alerting.

Documentation included

Handover that your team can maintain.

What Reliable CRM ↔ ERP Integration Unlocks

Integration is not “connecting two endpoints.” It’s enforcing one operational truth—across sales, purchasing, inventory, finance, and service—without spreadsheet bridges or inbox approvals.

Quote-to-cash

Accurate quotes with controlled approvals

Sync price lists, discounts, margins, and approvals—then push validated orders into ERP without re-keying.

Explore Quote-to-Cash

Inventory visibility

Availability that sales can trust

Expose stock, reservations, lead times, and allocation rules—so CRM decisions match warehouse reality.

Explore Inventory Control

Procurement governance

RFQ → approvals → PO with audit trail

Standardise vendor offers, approval gates, and purchase orders—then track changes end-to-end.

Explore ERP for Procurement

Returns & claims

Traceability without chaos

Link returns, serial/lot, root-cause, and corrective actions—so service doesn’t break finance and stock.

API Integration Capabilities (Built for Operations)

The goal is predictable operations: consistent data, controlled workflows, and integration behaviour your team can monitor and improve.

API Governance

Standardised authentication, versioning, error formats, and deprecation policies—so integrations remain stable as your platform evolves.

  • Versioning & backward compatibility strategy
  • Rate limiting, throttling, and abuse protection
  • Consistent error standards & validation

Event-Driven Reliability

Webhooks and events designed for real systems: signed payloads, retries, idempotency, and queue-backed processing.

  • Signed webhooks + replay protection
  • Idempotent handlers (duplicates are safe)
  • Retry + dead-letter strategy for failures

Observability & Control

You can’t run what you can’t see. Integrations ship with logs, metrics, and dashboards that expose drift and failures early.

  • Structured logging (correlation IDs, event IDs)
  • Latency/error-rate tracking + alerting
  • Sync health reports (drift, backlog, retries)

How API Integration Delivery Works (End-to-End)

Fast starts, controlled rollouts. The objective is to deliver integrations that remain stable under load and transparent under failure.

  1. Step 1

    Integration audit & data model mapping

    Identify source-of-truth rules, field mappings, sync directions (one-way vs bi-directional), and failure scenarios.

  2. Step 2

    Contract design (APIs, events, governance)

    Define versioning, authentication, error standards, idempotency keys, and webhook signing.

  3. Step 3

    Build, test, and observe

    Implement integrations with automated tests, structured logs, correlation IDs, and dashboards.

  4. Step 4

    Controlled rollout

    Release in stages, monitor sync health, and protect operations with retries and fallbacks.

  5. Step 5

    Handover & support

    Deliver documentation, runbooks, and a stabilization window—or ongoing ownership if required.
