Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DISCO

Per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.
Hosting is cloud only in United States regions, so matters with European, United Kingdom or Australian data residency requirements are excluded outright.
Review analytics, scripting and the third-party application ecosystem remain deeper on Relativity, which matters for firms with established review workflows.
As a listed company reporting losses, it has been through leadership change including the founder departure in 2023, so multi-year roadmap commitments carry more risk than with a private vendor.
Complex productions and unusual data types still require professional services, so the promise of self-service holds mainly for mainstream email and document collections.

Tabs3

The interface follows Windows desktop conventions from an earlier era, so new fee earners and staff take longer to train than they would on a browser-based competitor.
On-premises deployment puts backup, disaster recovery, server upgrades and patching on the firm, which small practices without IT support routinely underestimate.
It is built around hourly and flat fee billing, so a contingency practice tracking case costs and settlement disbursements will find the case financial model a poor fit.
PracticeMaster case management is priced separately from billing, so the advertised per-user rate is not what a firm wanting matter management actually pays.
Choosing the on-premises option no longer avoids a subscription, because it is billed per user per month like the hosted version.

Answered from the vendors’ own pages

DISCO: How is DISCO priced?

Per gigabyte of hosted data per month, all-in, with unlimited users. There is no published rate card, so it is quoted.

Tabs3: Is Tabs3 right for a personal injury firm working on contingency?

No. It is built for hourly and flat fee billing with a firm general ledger. A contingency practice needs case cost tracking and settlement disbursement handling, which is what CASEpeer and Filevine are built around.

DISCO: Can data be hosted outside the United States?

Coverage is centred on United States cloud regions, so confirm residency before shortlisting for European or Australian matters.

Tabs3: Can I still buy Tabs3 as a perpetual licence?

No published perpetual price exists. The on-premises option, called OnSite Subscription, starts at 69 USD per user per month, with the hosted Tabs3 Cloud starting at 89 USD per user per month.

DISCO: Is it cheaper than Relativity?

On small and mid-sized matters usually yes, because seats and analytics are included. On very large collections the volume charge often overtakes a negotiated Relativity arrangement.

Tabs3: Does it replace QuickBooks?

For most firms yes. It includes a double-entry general ledger and accounts payable, which is the usual reason firms choose it over billing-only products.
