"Integrated Client Portal Enhances Agency Productivity"

4.5/5

What do you like best about Assembly?

I appreciate Copilot for being a smooth and integrated platform that seamlessly incorporates with our systems. It's incredibly easy to set up, particularly with third-party embedding which is very useful. The live reporting and file access save our team extensive admin work by allowing clients to locate data independently. The chat function enables clients to contact us quickly, enhancing communication. Review collected by and hosted on G2.com.

What do you dislike about Assembly?

I find that managing workspaces for different clients on the back end of the portal can become quite cumbersome. The embed and app section tends to get busy because different clients have different services. It would be much more efficient if I could switch between clients more easily when setting up the portal. Review collected by and hosted on G2.com.

Hi Charlie,

Thank you for sharing such a thoughtful review! We’re glad to hear that Copilot has made it easier for your team to manage reporting, file access, and client communication. It’s great to know that features like live reporting, chat, and third-party embedding are helping reduce admin work and enhance your clients’ experience.

We also really appreciate your feedback on managing workspaces and the embed/app section. We hear you—switching between clients should be more seamless, and this is an area we’re actively working on improving. Input like yours helps us prioritize the right updates so that Copilot continues to fit smoothly into the way agencies operate.

Thanks again for trusting Copilot to support your team’s productivity—we’re excited to keep making the platform even better for you.

"Copilot is one of the best softwares I've came across in a while."

5/5

What do you like best about Assembly?

Copilot makes the customer buying experience seamless. No more manual email back-and-forths — we save so much time, and every file is automatically organized by client. It’s been excellent. Review collected by and hosted on G2.com.

What do you dislike about Assembly?

I think not being able to add another user for a flat fee is tough. The basic plan should really allow at least 2 users — jumping from 1 to 3 for an extra $150 per month feels like too big of a leap. Also, more app integrations are definitely needed. Right now, most of them are very similar in functionality. It would be great to see options like order tracking apps, quoting apps, and other tools that expand the platform’s capabilities. Review collected by and hosted on G2.com.

What problems is Assembly solving and how is that benefiting you?

Copilot is mainly smoothing out the messy parts of your customer workflow. Instead of juggling long email threads, hunting for files, or losing track of revisions, everything for a client lives in one place automatically. That means:

Time saved: no more back-and-forths trying to confirm which file is “final” or re-sending the same info multiple times.

Clarity: every client has their own organized hub, so nothing gets misplaced.

Consistency: processes run the same way across clients, which makes it easier to scale without chaos. Review collected by and hosted on G2.com.

"Game-Changer for Client Onboarding – Copilot Delivers"

5/5

What do you like best about Assembly?

We’ve recently started using Copilot as our onboarding portal at 19 Six Media, and it’s been a game-changer. The platform is incredibly intuitive and easy to set up—perfect for creating a smooth, professional experience for new clients.

What really stands out is the support team. For the trickier bits, their help has been fast, clear, and genuinely helpful. It’s rare to find a tool that balances ease of use with powerful features, but Copilot nails it.

Highly recommend to any business looking to streamline their onboarding and deliver a seamless client experience. Review collected by and hosted on G2.com.

What do you dislike about Assembly?

The only drawback we’ve found so far is the lack of native automations, which would make an already smooth process even more powerful. That said, the team at Copilot is actively working on this, and based on their responsiveness so far, we’re confident it’s coming soon. Review collected by and hosted on G2.com.

What problems is Assembly solving and how is that benefiting you?

Copilot has solved a major gap in our client onboarding process by giving us a centralised, professional platform to manage communication, document sharing, and onboarding steps. It’s eliminated messy email chains, reduced back-and-forth, and created a far more polished experience for new clients. The ability to guide clients through a clear, branded portal has helped us make stronger first impressions and get projects moving faster with less friction.

"Decent Tool, Needs Flexible Billing Options"

2/5

What do you like best about Assembly?

I appreciate the client management and messaging feature that Copilot offers as they enhance communication efficiency. The platform is professional, which leaves a good impression on clients, and it has comprehensive all-in-one features. Though not utilized extensively, I see the potential of the knowledge base for client training. Review collected by and hosted on G2.com.

What do you dislike about Assembly?

I find the setup process for Copilot to be quite challenging and not as user-friendly compared to other tools like Bonsai. The inability to manually reorder tasks is frustrating, as it requires adding tasks in reverse order to display them correctly. The biggest shortfall, however, is the payment collection system. Being in Canada and billing clients in US dollars should be straightforward, as it is with other services I use, but with Copilot, it becomes a complex issue. The initial setup with my Stripe account led to rejected deposits because Copilot did not handle the currency correctly, forcing me to reconfigure it to Canadian dollars. This limitation has rendered the invoicing feature essentially useless for my needs. Additionally, the integration issues with QuickBooks further complicate billing, as I cannot seamlessly manage US dollar transactions. The high subscription cost of Copilot feels unjustified when the key features like invoicing do not work for my international billing needs. Review collected by and hosted on G2.com.

Hey Brad,

Copilot Co-Founder here! Thank you for taking the time to share such thoughtful and candid feedback. I’m so glad to hear that our client management, messaging features, and professional interface have enhanced your experience with both clients and your team.

I also appreciate your clear notes on where the experience could be improved. While we may not be able to address every point right away, I’ve shared your feedback with our product team, and it will absolutely help guide our prioritization discussions for the coming quarters.

Billing — especially for international transactions — is an area we aim to handle as thoughtfully and intentionally as possible. We understand the frustrations you’ve had with currency handling, invoicing, and integrations, and we’re committed to iterating on this experience to better support both domestic and international scenarios. As recently as 2 weeks ago, we updated our QuickBooks integration to make it more frictionless and robust, directly addressing pain points that customers like you have raised. Feedback like yours is exactly what helps make those updates possible.

Thanks again for sharing your perspective. Customers like you play a huge role in helping us evolve Copilot into the best possible platform. I've also reached out to you via email in case you’d like to share any further thoughts now or in the future.

— Marlon
