Tailored Energy Consultancy Marketplace: Key Requirements

The client was looking for a culturally adept team that understood his personalised requirements. Along with this, he wanted a marketplace capable of supporting extensive customization while maintaining scalability for future business growth.

The marketplace specifications included complete ownership of the platform, along with the flexibility to implement custom workflows, localized features, and advanced marketplace capabilities tailored specifically for the German energy consultancy industry.

To align with the client's vision, we tailored the following marketplace enhancements.

  • Intelligent Keyword-Based Search
  • Radius-based Search using Postal Codes
  • German-specific Localization
  • Secure proposal visibility controls
  • Advanced Job Email Notifications
  • GDPR-inspired Account Deletion
  • Gated Digital Portfolio
  • Admin-configurable Marketplace Settings

To start onboarding ESG professionals, the client also required our in-house digital marketing team's assistance.

Client's Vision / From Ideation to Execution

The client's vision was to eliminate the industry gaps and modernize Germany's energy consultancy sector by introducing an intelligent marketplace ecosystem.


Location-based Service

Location-based Service Discovery


The client envisioned offering a personalised and localised user experience to all the registered stakeholders from Germany, nurturing local connections. Energy consultancy projects are often location-dependent, making accurate regional search capabilities essential. Hence, country names, postal codes, city information, and search filters are all needed to reflect local user expectations.

Sample 01

Privacy- First Proposal Management


The client wanted proposal details to remain completely private, ensuring that only the project owner and the submitting consultant could access proposal information. The business owner wanted to abide by strict confidentiality, role-based access control, and secure document exchange to prevent unauthorized data visibility by competing consultants and unauthorized third parties.

Offers Regulatory

Offers Regulatory Compliance


The client enquired about the integration of account deletion workflows aligned with GDPR-inspired practices to allow administrators to manage user accounts efficiently. This enables the admin to block registered users with active BAFA or iSFP documents from accessing their accounts. Furthermore, the business owner was looking to offer energy-efficient German housing by listing vetted consultants who grant application support for German-specific subsidies, like BAFA, FFW, and ISFP.

Marketplace Integrity and Flexibility


The client required different budget visibility rules for guests, freelancers, and clients to encourage registrations while maintaining confidentiality. Additionally, the business owner was looking for unconstrained and dynamic pricing to lure specialist niche users as well as eliminate floor price, to invite novice consultants starting their venture. Also, the client displayed interest in the min and max range of radius filters for enhanced flexibility.

Precision Strategies Tailored for The Business

For maximum alignment and results, the following are the customisation particulars for Bauherr.Digital- business model.

Email Notification Templates & Range Filters


The client requires email templates to send job posting notifications to freelancers within a 50 m geographical range, along with an email notification to the admin. Moreover, the email notification for bids, new messages, and secured jobs is also included in the feature spec.

Geo-Targeted Specifications


The user will be able to search for job postings and freelancers within a custom radius range. Moreover, the admin will be given the provision to min and max the radius filter range. Furthermore, for local expansion, the country filter was removed from the frontend listing filters.

GDPR-Compliant Account Deletion


This feature enables admin-triggered account deletion GDPR-compliant on your blank database, which completely removes the user record and their related ratings, while safely handling past orders for tax and legal compliance. This feature also allows deletion for both confirmed and unconfirmed accounts using a unified deletion service.

Advanced Keyword Search


Users can seamlessly search jobs and freelancer professionals through keyword-based search, segregated by skills, categories, descriptions, soft skills, ZIP code, and more. The functionality enables the system to show smart auto-suggestions to help you find the best match fast.

Renovation Calculator: Third-party Integrations


The business owner was looking for a client-converting system that assisted in achieving client acquisition and retention. Hence, as demanded, we integrated a renovation calculator into the marketplace, enabling initial cost estimation, prioritisation of measures, and matching with suitable experts.

Private Proposals and Budget Privacy


To encourage guests browsing through the website, the business owner wanted to introduce a feature that shows freelancer details and proposal amounts only to the client and that specific freelancer. We implemented the feature to hide proposal details from users and client budget prices for both logged-in and logged-out users.
