What would your migration cost?

Answer three questions about your GP environment. The figure updates as you go, and you can send it to us as a quote request. Nothing here commits you to anything.

What your business runs in GP

Pick every module you use today. Modules you skip are left in GP or retired.

What has been built on top of it

Rough counts are fine. The assessment inventories the real list from your database and the files you share, so nothing here is binding.

How big the estate is

Companies are separate GP company databases. History is the number of fiscal years you want in Business Central, not just accessible.

Preliminary estimate

Modelled on 445 partner hours for this scope.

Traditional partner	$66,000–$99,000
Duration	10–15 weeks
Comostasis	$8,000–$16,500
Duration	2–3 weeks

Roughly 80–90% less than a conventional engagement. The fixed quote comes from the assessment, which inventories your actual environment.

How the estimate works: the conventional figure models partner hours per module and per custom item at a blended mid-market rate, using published ranges from GP-to-BC providers. The Comostasis figure is modelled at 10–20% of that, the share of the work we expect an evidence-driven inventory and agentic execution to leave. Both are ranges because your counts are approximate; the assessment replaces them with the real inventory and a fixed price.
