For our Hamburg tax practice, its built-in alignment with German fiscal regulations is its biggest strength. All client tax files, quotation records and consultation logs reside entirely on EU servers, eliminating any regulatory risk of cross-border data transfers under GDPR. Its granular role-based access controls let me strictly segregate sensitive financial data: junior admin staff only get read-only entry to basic contact details, while senior accountants hold full editing rights to profit statements and VAT documents. Every single modification, invoice upload or client note generates permanent, uneditable timestamped audit trails that local Finanzamt auditors accept as-is with zero extra formatting work. The full German-language interface also cuts onboarding time for new tax clerks and minimizes daily support questions. Review collected by and hosted on G2.com.

There is no native two-way API connection compatible with our GoBD-certified German accounting ERP. Each month-end closing, I manually copy over customer invoice records, revenue figures and payment data between platforms, a slow, error-prone process that eats up several work hours. Permission management is extremely tedious without a bulk editing feature. Whenever we hire new junior tax specialists or restructure internal teams, I have to manually adjust access settings for every individual user profile one by one. The system’s default audit output templates do not follow the standardized archive layout required by German tax authorities, so I always spend extra time restructuring exported log files ahead of official Finanzamt inspections.

Most major CRMs require an expensive integration or an entirely separate app to handle the money side of things. 1CRM includes robust Order Management right out of the box. You can create quotes, turn those quotes into invoices, track sales orders, and even manage supplier bills and product inventories without leaving the ecosystem.

The user interface (UI) can feel like a throwback to the software designs of the early 2010s. Because it packs so much data onto a single screen, the dashboards and menus often look cluttered, dense, and utilitarian. Compared to the slick, minimalist, and highly intuitive interfaces of modern competitors like HubSpot or Monday.com, 1CRM has a much steeper learning curve for teams to adopt willingly.

The best thing I like about this one CRM platform is it goes beyond the traditional CRM functionality and combine all module such as sales marketing customer service and project management even invoicing and order management everything in a single platform in a centralised way this platform offers a very strong level of customization allowing or business to tailor workflows modules and reporting based on operational requirements this flexibility makes this platform very useful for our organization who wants a centralised system rather than managing multiple disconnected tools out there and another major advantage of this platform is their breath of features available at relatively competitive price point compared with other large enterprise CRM platforms out there they are integrated level approach helps us platform to improve visibility across or cross functional teams reduces the operational mismatch hassles.

Though this platform is very strong and helpful they are interface sometimes feels bit outdated when compared with other cloud native CRM platforms and some new users may find it difficult during the onboarding process because of their complex learning curve and since this platform is highly configurable they are set up administration can become slightly complex for a smaller teams without any CRM administrators some of their workflows and user interface interactions should be modernised and polished their platform is feature rich certain integrations and automation capabilities may not feel as polished as the CRM ecosystem out there.

What I like most about 1CRM is its true all-in-one functionality. Instead of juggling multiple disconnected tools, it centralizes CRM, sales pipeline management, marketing automation, customer support, and project management into a single platform. That consolidation not only reduces costs but also eliminates data silos, making it much easier to maintain a clear, real-time view of every customer interaction from first touch to post-sale support.

From a sales perspective, the platform allows for detailed pipeline tracking, opportunity management, and forecasting, which helps teams stay organized and proactive. On the marketing side, the built-in automation tools make it easier to run targeted campaigns, segment audiences, and track engagement without needing a separate system. Customer support is also integrated, so teams can manage tickets, monitor response times, and maintain consistent communication, all while having full visibility into the customer’s history.

Another major strength is its level of customization. Businesses can tailor workflows, dashboards, and reporting to match their exact processes rather than forcing their operations to fit a rigid system. This flexibility makes it scalable for different team sizes and industries. Overall, having everything connected in one ecosystem improves efficiency, reduces friction between departments, and creates a more cohesive experience for both the team and the customer.

What I dislike about 1CRM comes down to a few practical limitations that can slow teams down if you are trying to scale or move quickly.

The user interface feels somewhat outdated compared to newer CRM platforms. While it is functional, it is not very intuitive, which creates a learning curve, especially for team members who are not very technical. Even simple tasks can require more steps than expected, and over time that extra friction can impact overall efficiency.

Another issue is that while the platform is highly customizable, that flexibility can become overwhelming. Setting up workflows, automations, and reports often requires a deeper understanding of the system. It is not always plug and play, so without someone dedicated to configuring it properly, teams may not fully use its capabilities or may build processes that are not optimized.

Integrations can also be limiting. Compared to more modern CRM systems, the available native integrations are fewer, which can make it harder to connect with newer tools or specialized software. This becomes more noticeable if your business relies on multiple platforms working together. Review collected by and hosted on G2.com.

What I appreciate about 1CRM is that it serves as an all-in-one, customizable platform that unifies sales, marketing, customer support, and project management. This integration makes it straightforward to track customers, oversee projects, and generate helpful reports. Additionally, I value that it remains affordable and provides the flexibility of both cloud and self-hosted deployment options. Review collected by and hosted on G2.com.

At times, 1CRM’s interface feels a bit outdated, and getting accustomed to certain features can take additional time because of the system’s detailed nature. The setup and customization process is often slow, and some modules do not offer the modern, seamless experience that other CRM tools provide. Review collected by and hosted on G2.com.

1CRM is a great crm with inventory management and sales forecasting tools that are very helpful in business process and also it’s ability to integrate with multiple online as well as offline software’s is really great. Review collected by and hosted on G2.com.

Although the CRM is great but support is really slow and any complaint takes weeks to get resolved Review collected by and hosted on G2.com.

I like how 1CRM creates a more convenient way to store client info. It's valuable because when dealing with inbound or outbound call sales, it's crucial to have the right system for client sales information. 1CRM categorizes interactions, helping to identify what clients want and which numbers work. It’s easy to use, making it simple to figure out client preferences based on each human interaction. Review collected by and hosted on G2.com.

Sometimes it's a bit of a challenge because it requires a team effort to run and maintain the system. It would be better if there was a feature that verifies each client's information, like numbers and addresses, to make sure one person doesn't have to carry the load.
