What the pricing really means
At first glance, Tabs3 looks cheaper at $60/month vs $70/month. But sticker price is only part of the story. Look at what is included on the base plan, how many users you get, and whether you need add-ons to get the features you actually need. The $99/month plan that requires $200 in add-ons is actually more expensive than the $250/month plan that includes everything.
Where AppColl wins
- Direct USPTO and WIPO integration pulls filing deadlines, status updates, and correspondence automatically
- Patent/trademark portfolio management with annuity and renewal tracking across jurisdictions
- Foreign filing management handles multi-country patent strategies
- 14-day free trial for IP-specific workflows
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 AppColl falls short
- Only useful for IP law — zero value for any other practice area
- No trust accounting, no eSignature, no mobile app
- No intake forms or conflict checks
- Smaller company, so support options are limited compared to Clio
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
