Every Salesforce consultant will tell you it depends. And they are right — but that answer is not useful when you are trying to plan a business change.
| Phase | What Happens | Realistic Duration |
|---|---|---|
| Discovery & scoping | Requirements gathering, process mapping, scope sign-off | 1–2 weeks |
| Configuration | Building out objects, fields, page layouts, flows, automations | 2–6 weeks |
| Data migration | Cleansing, mapping, and importing data from existing system | 1–3 weeks (can run parallel) |
| UAT (User Acceptance Testing) | Your team tests real scenarios before go-live | 1–2 weeks |
| Go-live & stabilisation | Launch, monitor, fix edge cases, train users | 1–2 weeks |
| Total (basic) | Sales Cloud, 1–5 users, standard config | 3–5 weeks |
| Total (mid-complexity) | Custom flows, integrations, data migration | 6–10 weeks |
| Total (full enterprise) | Multi-cloud, complex integrations, large teams | 10–16 weeks |
After 10 years of delivering Salesforce implementations across Ireland, Norway, and the UK, I can give you real timelines — and more importantly, I can tell you what actually drives the difference between a 3-week implementation and a 3-month one.
Realistic Timelines by Project Type
Basic Sales Cloud setup (1–5 users, standard pipeline): 3 to 5 weeks from kickoff to go-live. This covers initial discovery, configuration of Accounts, Contacts, Opportunities, and Activities, basic email integration, reports and dashboards, and user setup.
Mid-complexity Sales or Service Cloud (5–20 users, custom processes): 6 to 10 weeks. This covers more complex configuration — multiple sales processes, territory management, approval processes, Flow automation, integration with one or two external systems, custom reports, user training, and a proper data migration. Not sure which Salesforce product your project needs? Here’s how to choose between Sales Cloud and Service Cloud.
Full implementation with data migration (20+ users or multi-cloud): 10 to 16 weeks minimum. Once you are dealing with a large user base, multiple Salesforce products, complex integrations, or a significant volume of data to migrate and clean, the project needs more phases and more testing time.
Remediation of an existing implementation: 4 to 8 weeks, depending on what was inherited.
What Speeds an Implementation Up
You know your business process before we start. The single biggest factor in implementation speed is how clear you are about how your business works.
One clear decision maker. Implementations slow down when approval loops grow. Having one person with authority to say yes or no dramatically compresses timelines.
Clean data for migration. If your data is already reasonably clean, migration is a manageable task.
Available users for testing. At the testing stage, I need your actual users to put the system through its paces.
What Slows an Implementation Down
Changing requirements mid-project. Every time the scope changes after it has been agreed, the project that was 70% done becomes 50% done. This is the most common source of implementations that take twice as long as originally planned.
Integration complexity. Connecting Salesforce to external systems adds time that is hard to predict.
Messy data. Data migration from a legacy system with years of accumulated inconsistency is one of the most time-consuming activities in any implementation.
Stakeholder availability. Implementations need decision-making input at key points. If the person who needs to approve decisions is unavailable, the project waits.
Getting a Real Timeline for Your Project
The only way to give you an accurate timeline is to understand your specific situation — your process, your data, your integrations, and your team. That is what the free planning call is for. In 30 minutes I can give you a realistic scope, a timeline, and a fixed price. For context on what the investment looks like alongside the timeline, see the implementation cost guide for Ireland.
