Single-purpose competitor · agency-priced
Retainerkit
The closest like-for-like — Retainerkit also does retainer hours and only retainer hours. Both products do the same thing. They disagree about who the user is: Retainerkit at $49/mo assumes a 10-seat agency with a per-client portal; HourTab at $9–$19/mo assumes one freelancer with 3–10 retainers and a public URL.
All-in-one freelancer suite · bundles invoicing, contracts, tasks
Bonsai
Bonsai is the freelancer operating system: invoicing, contracts, proposals, time tracking, taxes, and a client portal that has a retainer view inside it. The decision is whether your bottleneck is “I’m juggling ten freelancer tools” (Bonsai) or “the retainer-status email keeps eating my afternoons” (HourTab).

All-in-one freelancer suite · white-label client portal
Plutio
Plutio packages nine modules (CRM, proposals, contracts, invoicing, projects, tasks, forms, time tracking, portal) into a white-label client portal — same all-in-one shape as Bonsai, with a different pricing model. Both tools sit at $19/mo at the entry tier, which makes the per-feature trade-off the cleanest comparison in the set.
