Acumatica SaaS Subscription Comparison

Since you're on a 10-year-old subscription, you're most likely still on the legacy licensing model (pre-2024 named-user/edition structure). Acumatica moved to a new licensing model back in April 2024 that changed how things are measured — it's no longer just "modules," it's a mix of Edition + Reserved Resources + consumption (CTV/ETV transaction volume) instead of the older structure you're probably used to.

So a straight 1:1 "these old modules = these new modules" mapping doesn't really exist anymore, which is why this can get confusing.

A few practical points:

1. Field Service Edition still exists as one of the named editions, so most of what you listed (Service Management, Equipment Management, Contract Management, Customer Management with Portal) should still map into that edition or be available as add-ons under it.
2. Resource Level (L2) has been replaced by the Reserved Resources model — this is probably the biggest change for you. Instead of a fixed resource tier, you now pick reserved compute resources separately, which can actually work out cheaper or more scalable depending on your usage pattern.
3. Personalized Domain and SSL are typically still separate add-ons, not bundled into the base edition, so that likely carries over as-is.
4. Deferred Revenue — double check this one specifically, as some financial modules got reshuffled between "included" and "optional" depending on edition in the newer guide.

Honestly, the best move here: pull the latest official Acumatica Licensing Guide (they publish an updated PDF every year, currently the April 2026 version) — it has an Appendix with edition-by-edition datasheets showing exactly what's included vs optional. But since your account is 10 years old, your cleanest path is to reach out to your Acumatica partner/VAR and ask for a like-for-like migration comparison — they can pull your current entitlements and map them against the new model directly, since a lot of this depends on your actual transaction volume (CTV/ETV) too, not just feature checkboxes.
