Why are your teams still maintaining customer data twice?

weclapp is a cloud-based ERP for inventory management, order processing, and accounting. CAS SmartWe organizes contacts, sales opportunities, and appointments with an intuitive interface particularly designed for small sales teams. Both systems originate from Germany and rely on cloud hosting with GDPR compliance.

The weclapp CAS SmartWe Integration connects sales activities with operational order processing. Leads from SmartWe become customers in weclapp, orders and invoices flow back into the CRM. Your teams work with current data without jumping between systems.

Where does the weclapp SmartWe interface help concretely?

Here are six scenarios where the connection provides noticeable relief:

Leads become customers without copy-paste. Qualified sales opportunities from SmartWe are automatically created as customer master data in weclapp. Sales captures contact details once, accounting and order management continue working directly with them.

Play orders and invoices back into CRM. Sales orders and invoices from weclapp appear in SmartWe at the customer contact. Sales sees the current order status, outstanding items, and delivery dates without switching to the ERP.

Provide article data for sales. Product catalog, prices, and availability from weclapp are available in SmartWe. Quotes are based on real inventory levels and current price lists, instead of outdated Excel tables.

Keep contact master data synchronized. Changes to contacts, addresses, or communication histories in SmartWe flow to weclapp. Accounting sends invoices to the correct address, logistics delivers on time.

Link sales opportunities with order status. Opportunities in SmartWe show the fulfillment status from weclapp. Sales managers recognize whether an order has been delivered or is delayed, and can communicate proactively.

Enrich support tickets with order history. Tickets in SmartWe automatically show the latest orders and invoices from weclapp. Customer service has all information to respond quickly.

From Integration to Results

The use cases on this page are not theoretical, but implementing them requires experience. You can set up integration and data management yourself through MARINI’s no-code interface, or have our team configure it for you. For implementation in your systems, we work collaboratively with you and your service providers. If you don’t yet have a suitable service provider, we’re happy to recommend an appropriate partner from our network.

Utilize REST APIs on both sides. weclapp and SmartWe offer modern REST APIs. MARINI connects both systems via standardized interfaces. You don’t need to install proprietary adapters or maintain custom code.

Configure field mapping and transformations. Customer data in SmartWe has different names than in weclapp. MARINI maps the fields in a no-code interface. You define which attributes are synchronized and which values need to be transformed.

Resolve conflicts and avoid duplicates. When the same contact is changed in both systems, you decide which system is leading. MARINI recognizes duplicates based on defined criteria and prevents duplicate records.

Logs and monitoring in real-time. Every synchronization is logged. You see which records were transferred, where errors occurred, and how long processes take. Alerts inform you when something goes wrong.

Frequently asked questions about weclapp CAS SmartWe connection

Typically, customers and contacts from weclapp are synchronized as companies and contacts in SmartWe. Sales opportunities from SmartWe can become quotations or sales orders in weclapp. Invoices, delivery notes, and article data flow back into the CRM. The integration also supports custom attributes if you have defined specific fields.

MARINI supports both. You can use webhooks to transfer changes immediately, or define a schedule that synchronizes data at fixed times. Real-time is recommended for time-critical processes like order creation, while nightly runs are often sufficient for master data updates.

That depends on your process. Often SmartWe is leading for sales activities and initial contact data, while weclapp remains the authoritative source for billing addresses and payment information. MARINI allows bidirectional synchronization with configurable conflict rules, so you can flexibly control data sovereignty.

Yes. Both weclapp and SmartWe allow individual fields. MARINI recognizes these attributes via the APIs and you can consider them in field mapping. If a custom attribute exists in one system but not in the other, you can define default values or transformations.

MARINI offers matching rules based on email, company name, or external IDs. If a contact already exists in both systems, it is linked instead of newly created. You can also implement manual review processes where uncertain matches are marked for verification.

No. MARINI connects via the native REST APIs of both systems. You don’t need to install any extensions. The integration runs entirely in the MARINI Cloud, hosted in the EU with ISO 27001 certification. On-premise connections are also possible if you operate parts of your infrastructure locally.

With MARINI’s integration solutions, we eliminate customer data silos and orchestrate marketing automation campaigns seamlessly across systems.
