Migrate to Business Central from any system

Pick your current system and see what the migration actually involves: what breaks, what is salvaged, what it costs and how long it takes. Split into parts, and each part is invoiced only after you accept it.

Planner: Migration planner. You choose the current system (Navision, Dynamics GP, Sage or another ERP, or spreadsheets), companies, years of history and custom changes, and it shows a six-phase plan with the weeks for each phase, what data moves and the risk without a phased plan. In the example, Navision 2009 with 2 companies, 3 years of history and quite a few customisations is about 21 weeks; from spreadsheets with few changes, about 9. Open the demo

Why migrate with us

The method, in five phases

  1. Assess: object inventory, data quality, integrations. Free, within five working days.
  2. Plan: what the standard covers, what is an app, what needs an extension. Scope split into parts with written acceptance criteria.
  3. Build and test: clean AL extensions, data validated against your live system, and your real month-end close run as a test.
  4. Cut over: usually a weekend, with the old system read-only as the fallback.
  5. Stabilise: first close supported, Power BI and AI agents switched on.

FAQ

Do we have to migrate all our history?

No. Masters, balances and open documents migrate; history is archived read-only. Migrating ten years of transactions is the most common way to inflate a quote.

Will our customisations break?

In a system with years behind it, a third to half of the custom code already exists in the Business Central standard. The inventory tells you before anyone writes code.

We already have a quote from another partner.

We will review it line by line within 48 hours — including telling you it is good.

What do licences cost?

$80 Essentials, $110 Premium, $8 Team Members per user per month. Full US breakdown.
