System Integration & ERP in Hong Kong
Connect your CRM, ERP, accounting, and business tools into a unified workflow. No more copy-pasting between systems, no more data silos, no more manual reconciliation.
What We Integrate
Most growing businesses run on a patchwork of disconnected tools — an ERP here, a CRM there, spreadsheets filling the gaps. Data gets re-entered, reports don't match, and teams waste hours on tasks that should be automatic. We connect your systems so data flows seamlessly between them, in real time.
We work with the platforms your business already uses:
- ERP systems — SAP Business One, Odoo, NetSuite, Microsoft Dynamics, ERPNext
- CRM platforms — Salesforce, HubSpot, Zoho CRM, Pipedrive, Microsoft Dynamics 365
- Accounting tools — Xero, QuickBooks, MYOB, Sage, FreshBooks
- Payment systems — Stripe, PayMe, FPS, Octopus, Adyen, PayPal, local HK gateways
- E-commerce platforms — Shopify, WooCommerce, Magento, custom storefronts
- Warehouse & logistics — inventory management, shipping providers, order fulfillment systems
- HR systems — payroll, leave management, employee onboarding, time tracking
- Custom APIs — proprietary internal systems, legacy databases, industry-specific platforms
How We Work
Integration projects fail when they start with code instead of understanding. Our process begins with your business processes, not your tech stack.
1. Systems Audit (Week 1–2)
We map every system, data flow, and manual process in your organization. We identify what data lives where, how it moves (or doesn't), and where the bottlenecks are. The output is a clear integration blueprint showing every connection, data transformation, and sync frequency.
2. Integration Architecture (Week 2–3)
We design the integration layer — which systems talk to which, what triggers data flows, how conflicts are resolved, and how errors are handled. You approve the architecture before we write a single connector.
3. Build Connectors (Week 3–8)
We build, test, and deploy each integration in phases. Critical connections go first. Every connector includes error handling, retry logic, logging, and monitoring from day one — not bolted on later.
4. Data Migration (Week 6–10)
If you're consolidating systems or switching platforms, we handle the data migration: schema mapping, data cleansing, deduplication, test imports, and validated final migration with rollback plans.
5. Testing & Go-Live (Week 8–12)
End-to-end testing across all connected systems. We run parallel operations, validate data integrity, stress-test sync volumes, and plan a zero-downtime cutover. Post-launch monitoring catches any issues before your team does.
Our Tech Stack
We use proven, maintainable tools for every integration layer:
- APIs: REST, GraphQL, SOAP, gRPC — whatever your systems speak
- Real-time sync: Webhooks, WebSockets, server-sent events
- ETL pipelines: Apache Airflow, custom Python/Node.js pipelines, dbt
- Middleware: Node.js, Python (FastAPI), message brokers
- Message queues: RabbitMQ, Redis Streams, AWS SQS, Kafka
- Database connectors: PostgreSQL, MySQL, MSSQL, MongoDB, direct DB links
- iPaaS: n8n, Make (Integromat), Zapier — for simpler flows where code isn't needed
We choose the right tool for each connection. Simple two-way syncs don't need enterprise middleware, and complex multi-system orchestrations shouldn't rely on no-code platforms. We'll recommend what makes sense for your scale and budget.
Who This Is For
- Businesses with data silos — your sales team can't see inventory, your finance team re-enters orders, your reports never match across systems
- Companies outgrowing manual transfers — you're copy-pasting between systems, exporting CSVs, or relying on staff to keep data in sync
- Enterprises needing real-time sync — departments need live data, not yesterday's export, to make decisions and serve customers
- Businesses switching platforms — migrating from one ERP, CRM, or accounting system to another without losing data or disrupting operations
Why Hong Kong Businesses Choose Astera
We understand the Hong Kong business software landscape — from local payment gateways (FPS, PayMe, Octopus) and banking integrations (HSBC, Hang Seng, Bank of China APIs) to the specific ERP and accounting tools popular in the HK market. We know which platforms play well together and where the pain points are.
Integration projects demand trust — we're touching your core business data. As a local Hong Kong team, we're available for on-site audits, in-person workshops, and same-day support. The engineer who architects your integration is the engineer who builds and maintains it. No handoffs, no offshore surprises.
Frequently Asked Questions
Yes. Not every system has a modern REST API, but most can still be integrated. We use database connectors, file-based exchanges (SFTP/CSV), screen scraping, RPA bots, and custom middleware to bridge the gap. We'll audit your systems and recommend the most reliable, maintainable approach for each connection.
We follow a structured process: audit existing data quality, map source-to-target schemas, build ETL pipelines, run test migrations in staging, validate data integrity, then execute the final migration with rollback plans in place. We handle deduplication, format conversion, and historical data archival as part of the process.
No. We design integrations to run in parallel with your existing workflows first. New connectors are tested in staging environments before going live. Cutover is planned for low-traffic windows, and we maintain rollback capabilities throughout. Most integrations go live with zero downtime.
Yes. Integrations need monitoring and maintenance as APIs evolve, data formats change, and business requirements shift. Our monthly retainer includes integration health monitoring, error alerting, connector updates, and support for adding new data flows as your business grows.
