Pros & Cons
Assembly
Pros
- Reviewers say a non-technical team can launch a polished, branded client portal quickly.
- Messaging, a CRM, invoicing, contracts, forms and files share one client login.
- A free plan and no-contract self-serve billing make it easy to test.
- SOC 2 Type II, AES-256 encryption at rest and a HIPAA BAA on Advanced suit regulated firms.
Cons
- Project management is basic, with no Gantt charts or dependencies.
- There is no native time tracking or scheduling.
- Automations lack conditional branching, and there is no native mobile app.
- Reviewers report a high cost and friction with international invoicing.
Flowlu
Pros
- Combines project delivery with CRM, invoicing and finance tracking, so service firms can track project profitability without separate accounting or sales tools.
- The free plan includes invoices, estimates and a basic wiki for two users, which is unusual for a project management tool.
- Capterra reviewers give high marks for value for money, and several say Flowlu replaced multiple separate apps.
- Projects can be viewed as lists, Kanban boards or Gantt charts, and mind maps can be converted into projects.
Cons
- Important features are spread across tiers. The client portal, billable hours and role-based access need Advanced at 22 USD per user per month, and white-labeling needs Ultimate.
- Some reviewers describe a steep learning curve at first because the suite has so many modules.
- Some reviewers say requests through the in-app support chat went unanswered.
- The free plan's limits of 100 contacts, one pipeline and one workflow are restrictive, and refunds are not offered on paid plans.
- The sources reviewed list no public security certifications or SSO.
