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.
Teamleader
Pros
- CRM, quotations, Peppol e-invoicing and time tracking come in one subscription, so small service firms can avoid separate billing tools.
- Reviewers on G2 and Capterra describe the interface as intuitive and easy to learn.
- Boosters can be added or removed at any time, so you pay only for modules you use.
- Discounts include 17 percent off annual billing and 50 percent off users from the sixth onward.
- A REST API, webhooks and integrations with Exact, Yuki, Mollie, Stripe, Gmail and Outlook are available.
Cons
- Boosters are priced per account, so total cost rises quickly once project management and planning are added.
- Reviewers report price increases that were poorly communicated, including one who said the annual price doubled.
- Customization is limited, and automation offers only simple triggers.
- Project management is weaker than in dedicated tools, with no task dependencies or capacity planning in Focus.
- Multiple sales pipelines are only available on the top FLOW plan.
