System Integration FAQs
Yes. We connect ERP systems (SAP, NetSuite, Odoo) with CRMs (Salesforce, HubSpot, Dynamics 365) so customer data, orders, and inventory sync automatically. This eliminates double data entry and gives your sales and operations teams a single source of truth.
The main risks are data loss, duplicate records, and format mismatches. We mitigate these by running a full data audit before migration, mapping fields between systems, cleaning duplicates, and running test migrations on a staging environment before touching live data.
Simple two-system integrations take 2 to 4 weeks. Complex multi-system projects involving legacy software, custom middleware, and data transformation typically take 8 to 16 weeks. We deliver in phases and test each integration point independently before connecting the full chain.
Costs depend on the number of systems, data complexity, and whether off-the-shelf connectors exist. Simple integrations using existing APIs start from £3,000. Enterprise-level projects with custom middleware and legacy system adapters range from £15,000 to £50,000+.
Yes. We offer monitoring and support plans covering error handling, data sync verification, API version updates, and troubleshooting. Integrations need regular attention because third-party APIs change, and we keep everything running smoothly.
