Custom Efficy CRM integration
Appfront develops custom Efficy CRM integrations that seamlessly connect your customer data with ERP, marketing automation, telephony, customer portals and in-house applications. Using Efficy's official REST and SOAP APIs, we build stable integrations that eliminate manual work and let your sales and service teams work with up-to-date data.
What is an Efficy CRM integration?
Efficy is a European CRM platform widely used across the Benelux, France and Germany by B2B organisations in professional services, wholesale, insurance, education and the non-profit sector. The platform offers a comprehensive REST and SOAP API that allows external systems to read and write contacts, accounts, opportunities, activities, campaigns and documents.
An Efficy CRM integration automatically connects your CRM with your ERP, marketing automation, telephony or own customer portal. Data flows from one system to another without manual effort: leads become opportunities, customers are invoiced, campaigns are tracked per contact and support interactions land directly in the customer record.
Appfront builds these integrations to measure through the official Efficy API. We tailor the scope, synchronisation frequency and error handling to your actual sales and service processes, rather than a standard connector that only solves part of the problem.
Real-time synchronisation
Changes in Efficy or in the connected system are passed on immediately or at an agreed frequency. Sales sees up-to-date data, marketing uses the right segments, and support works with the full customer picture.
Sales and service processes that keep themselves up to date
Leads, opportunities, activities and tickets are created and enriched automatically. Less duplicate data entry, fewer forgotten contact moments, and more time for the conversations that really matter.
Via the official Efficy API
Implementation in line with the Efficy REST and SOAP specifications, with clear error handling and extensive logging. No reverse engineering or undocumented endpoints.
Our development process for Efficy CRM integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your sales, marketing and service processes through to go-live and ongoing management, every step is aimed at an integration your team can understand and trust.
We map out which Efficy entities are relevant, such as contacts, accounts, opportunities and activities, and the direction in which data should flow.
We design the integration architecture, choose the right authentication and draw up an error-handling strategy.
Implementation with automated tests, structured logging and monitoring. You see working builds along the way.
Controlled go-live with data validation and a safety net, followed by ongoing management and further development.
What an Efficy CRM integration delivers in practice
Each integration is developed specifically for your business processes. Below are the features we most often build for organisations that want to connect Efficy with the rest of their software landscape.
Leads and marketing automation
Leads from your website, campaigns and marketing automation tools, such as HubSpot, Mailchimp, ActiveCampaign or a custom landing page, flow automatically into Efficy. Campaign attribution, segments and opt-ins stay consistent, without duplicate entry.
ERP & accounting integration
Accounts and contacts in Efficy stay in line with your ERP or accounting package, such as Exact, AFAS, Accountview, SAP or Odoo. Sales invoices are generated automatically from won opportunities, and payment status is visible in the customer record.
Telephony and contact centre
Incoming and outgoing calls via Voys, 3CX, RingCentral or another VoIP platform are logged automatically in Efficy, including click-to-call, call notes and linking to the right contact person.
Customer portals
A customer or partner portal where end users manage their details, submit tickets or view documents, powered directly by Efficy. Support becomes faster, customers have more control, and your team handles fewer routine queries.
E-commerce & order flows
Orders from your webshop or B2B portal are automatically linked to the correct account in Efficy. Sales gets immediate insight into what customers buy, service has context for support questions, and marketing can segment more precisely.
Reporting and BI
Sales and service data from Efficy is combined with financial and operational data in custom dashboards or tools such as Power BI, Looker Studio or Tableau, for management and sector-specific reporting.
Typical use cases in practice
Depending on your type of organisation, an Efficy CRM integration can work out very differently. We see a number of patterns recur, and for each of them we have developed a working model.
B2B sales organisations
Sales teams working with long sales cycles, account planning and complex quotes benefit from a CRM that is woven into the rest of their stack. We connect Efficy to marketing automation, ERP and telephony so that every account conversation takes place with the full customer picture. See also our API integrations.
Professional services
Consultancies, IT suppliers and design agencies often manage their relationships in Efficy, but their hours and invoices in a separate package. An integration keeps opportunities, projects and hours in sync, from quote through to invoice.
Education & non-profit
Education institutions, industry bodies and funds use Efficy to manage members, donors, alumni and stakeholders. An integration with an LMS, donation platform or CMS ensures that enrolments, donations and communications automatically land in the right record.
Insurance and finance
Insurers, intermediaries and financial services providers use Efficy for policy and client management. An integration with back-office systems, claims portals and external data services gives you a complete file and helps you meet file-keeping requirements.
Technology we use
We build Efficy CRM integrations using modern, well-maintained stacks. The precise choice depends on your situation and preferences, so your own team can manage or further develop the integration. We are happy to work alongside other suppliers and deliver clear documentation.
Why choose Appfront for your Efficy CRM integration?
Appfront has extensive experience building API integrations for a wide range of organisations in the Netherlands. We always start with a thorough analysis of your existing systems and processes. An integration should not only work technically, but also add practical value to the way you work.
For every integration, we write clear documentation and make sure your own team, or any future supplier, can understand and manage it. No black box, just transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical and the functional side. This keeps communication short, prevents misunderstandings and speeds up decisions when choices need to be made during development.

Security and privacy in Efficy integrations
CRM data inherently contains personal data and falls under the GDPR. Appfront treats this as a starting point for every integration: we don't store unnecessary data, we encrypt sensitive information both in transit and at rest, and we document the data flows so that your record of processing activities stays up to date.
Authentication runs through secure methods such as OAuth 2.0, API keys with restricted permissions or IP whitelisting. We agree in advance which data actually needs to be exchanged and keep the integration's scope to a minimum in line with the GDPR principle of data minimisation.
More on our security approach: information security policy and CVD policy.
- GDPR-compliant data processing and data minimisation
- Encryption in transit (TLS 1.2+) and at rest
- Role-based access and least-privilege principles
- Audit logs with traceable data flows
- Automatic retries and dead-letter queues
- Monitoring and alerting for anomalies
- Secrets management in line with best practice
- Documentation for your record of processing activities
Frequently asked questions about Efficy CRM integrations
Answers to the questions we are asked most often about custom Efficy integrations.
An Efficy CRM integration is a technical link that allows Efficy, the European CRM platform, to exchange data with another software system. This happens through Efficy's official REST or SOAP API. Contacts, accounts, opportunities, activities and documents can then be synchronised automatically with, for example, ERP software, marketing automation, telephony or your own customer portal.
A custom integration makes sense when no standard connector is available for your combination of systems, or when an off-the-shelf integration doesn't fit your sales and service processes well enough. Organisations with non-standard data models, complex segmentations or sector-specific workflows often choose a purpose-built solution that fits their way of working completely.
The lead time depends on the complexity of the integration you need and on the availability of the systems at both ends. A simple one-way integration, such as importing leads, can be operational within a few weeks. Two-way synchronisation across multiple entities with fine-grained segmentation usually takes longer. After an intake meeting, we give you a realistic estimate.
We work with Efficy's official REST and SOAP APIs and build the integration layer using modern back-end technologies such as Node.js, Python, Laravel or .NET. Authentication is handled via OAuth 2.0, API keys or IP whitelisting. For scheduling, monitoring and error handling, we use tools such as webhooks, job queues and logging dashboards, depending on the requirements.
Costs are determined by the complexity of the data flows, the number of systems to connect, the required synchronisation frequency and the amount of custom business logic. Ongoing management, monitoring and support also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation.
Yes. CRM data contains personal data and therefore falls under the GDPR. All integrations are developed in line with Dutch privacy legislation and security best practices. We encrypt data in transit and at rest, use authentication methods with restricted permissions and keep the scope of the exchanged data to a minimum. Data flows are documented so that your record of processing activities stays complete.
Yes. Appfront regularly takes over existing integrations, including those originally built by another party. We start with a code and architecture review, document the integration and draw up a maintenance plan. From that point on, we can handle adjustments, extensions and monitoring.
Efficy is widely used by B2B organisations across Europe, in sectors such as professional services, wholesale, insurance, education and the non-profit sector. Any organisation that uses Efficy alongside other software, for ERP, marketing, telephony or customer experience, can benefit from an automated integration.
