Community FAQ

Questions by product

Fishbowl Inventory FAQ

How complex is the self-hosting setup for Fishbowl Inventory on-premise?

Fishbowl Inventory requires a Windows server environment for on-premise deployment, with dependencies on SQL Server for its database backend. The setup involves installing both the Fishbowl Server and Client software, configuring network permissions, and ensuring proper integration with QuickBooks. IT overhead can be significant, especially for teams without dedicated Windows server administration experience, as updates and backups must be managed manually.

Community insight informed by Reddit discussions

Does Fishbowl Inventory support offline functionality for inventory management?

Fishbowl Inventory primarily operates as a client-server application requiring network connectivity between clients and the server. There is no native offline mode for inventory transactions; all data input and updates must be done while connected to the server. However, some mobile scanning tools integrated with Fishbowl may cache limited data temporarily but still require syncing once reconnected.

Community insight informed by Hacker News discussions

Who owns the data stored in Fishbowl Inventory, and how is data privacy handled?

All inventory and manufacturing data entered into Fishbowl Inventory is owned by the customer, as the software is deployed on-premise. Since data resides on the customer's own servers, privacy and security controls depend on the customer's IT policies. Fishbowl does not access customer data remotely unless explicitly granted for support purposes. This model ensures full data ownership and control remains with the organization.

Community insight informed by Forums discussions

Are there any API limitations when integrating Fishbowl Inventory with other systems?

Fishbowl offers a SOAP-based API for integration, which supports common inventory and order management operations. However, the API can be limited in terms of real-time event handling and bulk data operations, often requiring custom development to work around these constraints. Additionally, the API documentation is somewhat sparse, so developers typically rely on community forums and support for advanced use cases.

Community insight informed by StackOverflow discussions

What are the options for migrating data out of Fishbowl Inventory if we want to switch systems?

Fishbowl Inventory provides export functionality for key data entities like inventory, orders, and bills of materials via CSV or Excel formats. However, there is no built-in full database export tool designed for seamless migration to other ERP systems. Migration often requires custom scripts or third-party ETL tools to transform and import data into the target system. Planning migration early is recommended due to these limitations.

Katana FAQ

Is Katana ERP available for self-hosting, or is it only cloud-based?

Katana ERP is a cloud-based solution and does not offer a self-hosted version. All data and operations are managed on their servers, so businesses must rely on Katana's cloud infrastructure for uptime and security.

Community insight informed by Reddit discussions

Does Katana ERP support offline functionality for production and inventory management?

No, Katana ERP requires an active internet connection to access and update production and inventory data. There is currently no offline mode or local caching available, which means real-time connectivity is necessary for accurate tracking.

Community insight informed by Hacker News discussions

Who owns the data stored in Katana ERP, and can I export it fully if I want to switch platforms?

Users retain full ownership of their data in Katana ERP. The platform provides export options for inventory, production, and order data in common formats like CSV. However, some complex relational data may require manual adjustments post-export for migration.

Community insight informed by Forums discussions

What are the main limitations of Katana ERP's API for integrating with custom tools or other software?

Katana offers a REST API primarily focused on inventory and order management. However, it currently lacks endpoints for advanced financial data and detailed production scheduling. Rate limits and API access tiers may also restrict high-frequency data syncs for large operations.

Community insight informed by StackOverflow discussions

How easy is it to migrate existing inventory and production data into Katana ERP from other systems?

Katana provides CSV import tools for inventory and product data, which simplifies initial migration. However, migrating complex production workflows or historical data may require manual setup or assistance from Katana's support team to ensure data integrity.

Community insight informed by Reddit discussions

MRPeasy FAQ

Is MRPeasy available for self-hosting, or is it strictly SaaS?

MRPeasy is offered strictly as a cloud-based SaaS solution and does not provide an option for self-hosting. All data and application logic are hosted on MRPeasy's servers, which means you cannot deploy it on your own infrastructure.

Community insight informed by Reddit discussions

Does MRPeasy support offline functionality or local data caching for sales operations?

MRPeasy requires an active internet connection to function and does not support offline mode or local data caching. All transactions and updates are processed in real-time through their cloud platform.

Community insight informed by Hacker News discussions

What are the data ownership and export capabilities in MRPeasy for compliance and backup?

Users retain full ownership of their data in MRPeasy and can export their data in common formats such as CSV and Excel for backup or migration purposes. However, data export features may vary depending on the subscription plan tier.

Community insight informed by StackOverflow discussions

Are there API limitations or rate limits when integrating MRPeasy with other sales or e-commerce tools?

MRPeasy provides a REST API for integration, but it enforces rate limits to ensure platform stability. The exact limits depend on your subscription plan, and higher tiers offer increased API call quotas. Detailed API documentation is available upon subscription.

Community insight informed by Forums discussions

What is the recommended migration path for teams moving from Odoo or other legacy ERP systems to MRPeasy?

Migrating to MRPeasy typically involves exporting your existing sales, inventory, and customer data from your current system in CSV or Excel format and then importing it into MRPeasy using their built-in import tools. Due to differences in workflows and feature sets, some manual configuration and data cleanup are usually necessary.

Odoo FAQ

How complex is it to self-host Odoo for a mid-sized company?

Self-hosting Odoo requires a solid understanding of Linux server administration, PostgreSQL databases, and Python environments. The installation itself can be straightforward using official Docker images or packaged installers, but configuring and customizing modules for business needs often demands technical expertise. For mid-sized companies, it’s recommended to allocate resources for initial setup, ongoing maintenance, and backups to ensure stability and security.

Community insight informed by Reddit discussions

Does Odoo support offline functionality or local-only operation without internet?

Odoo is primarily designed as a web-based ERP system that runs on local servers or cloud instances. When self-hosted on-premises, it can operate fully offline within the local network without internet access. However, certain features like real-time updates, external integrations, or cloud-based modules will not function offline. Users can access core modules such as inventory, manufacturing, and sales internally without internet connectivity.

Community insight informed by Hacker News discussions

Who owns the data stored in Odoo when self-hosted versus using Odoo’s cloud service?

When self-hosting Odoo, your organization retains full ownership and control over all data since it is stored on your own infrastructure. No third party has access unless explicitly granted. In contrast, using Odoo’s official cloud service means data is hosted on their servers under their terms of service, which may include data processing agreements. For maximum data privacy and ownership, self-hosting is preferred.

Community insight informed by StackOverflow discussions

What are the main API limitations when integrating Odoo with external systems?

Odoo provides a comprehensive XML-RPC and JSON-RPC API for external integrations, but it has some limitations: the APIs can be slower for bulk operations compared to direct database access, some modules may not expose all business logic via API, and version compatibility issues can arise during upgrades. Additionally, complex workflows often require custom API endpoints or server-side modules to fully support integration needs.

Community insight informed by Forums discussions

What are the recommended migration or data export paths from Odoo to other ERP systems?

Odoo supports data export in CSV and Excel formats for most modules, which can be used for migration to other ERP systems. For more complex migrations, it’s advisable to use Odoo’s built-in export tools combined with custom scripts or ETL tools to map data fields accurately. The community also provides migration scripts for popular ERP platforms, but careful testing is required to ensure data integrity and consistency.
