What the pricing really means
Tabs3 publishes their pricing upfront, which is a good sign. Centerbase requires you to contact sales for a quote. When a company hides pricing, it usually means the cost is high enough that they want a salesperson to justify it before you see the number. Always ask for total year-one cost, not just the monthly subscription.
Where Centerbase wins
- Financial reporting and profitability analysis is deeper than most competitors, with partner compensation tracking
- LEDES billing built in with proper compliance for corporate and insurance clients
- Multi-office and multi-entity support for firms with multiple locations
- Custom pricing means you negotiate based on firm size, which can work in your favor
Where Tabs3 wins
- Trust accounting is rock-solid with three-way reconciliation that bar auditors love
- LEDES billing support for firms with corporate clients that require it
- 300+ built-in reports cover virtually every billing metric a firm would need
- Been around for 40+ years, so the billing engine is thoroughly tested and reliable
Where Centerbase falls short
- No public pricing — you have to go through sales, and mid-market typically means $100-200/user/month
- G2 rating of 4.0 suggests the user experience has room for improvement
- Fewer reviews (80 total) than major competitors means less community knowledge base
- Probably overkill for firms under 10 attorneys
Where Tabs3 falls short
- Sold as separate modules (Tabs3 Billing + PracticeMaster), so getting full functionality means buying both
- No client portal, no intake forms, no eSignature, no mobile app — missing most modern features
- Interface looks like it belongs in 2005
- Cloud version exists but historically been on-premise, so the cloud experience feels bolted on
