Data entered once, not re-typed into three systems.

A new core system rarely stands alone. We connect it to the surrounding systems it needs to talk to — payroll, CRM, banking, reporting, e-commerce — so information is captured once and flows automatically instead of being re-keyed.

• Integration build against the architecture agreed in the design stage
• End-to-end testing of each data flow, including failure and retry behaviour
• Documentation of every integration point for future support and troubleshooting

• Working integrations between the new system and the surrounding landscape
• An integration reference document

Re-keyed data is where errors and delay creep in. Integration work is what turns a system implementation into a connected landscape — see "One core, every system in orbit" on the homepage for the shape of what this typically looks like.
