# Implementation **Implementation** is the technical phase of customer onboarding — the work between contract signature and the customer being live and using the product day-to-day. ## Typical workstreams - **Data import / migration** — from spreadsheets, prior tools, or APIs - **Integration setup** — connecting to existing systems (CRM, email, billing) - **User provisioning** — accounts, roles, SSO - **Configuration** — workflows, templates, automations - **Training** — admins first, then end users ## Implementation models - **Self-serve** — documented checklist, async support - **Concierge / standard** — CSM-led, 4–8 week guided plan - **Professional services** — paid implementation team, custom data work ## Implementation risk The two biggest risks: scope creep (the customer keeps adding requirements) and stakeholder churn (the buyer leaves the company mid-implementation). Mitigate with a tight scope doc and an executive sponsor on both sides. ## How BlueHill helps Implementation templates encode your standard methodology so every customer gets the same proven sequence. Internal notes keep the team aligned on customer-specific nuances without polluting the customer-facing view. Related: [Onboarding](/glossary/onboarding) · [Kickoff](/glossary/kickoff)
