From dispatching and the automated weighbridge to electronic waste records – CONWIN maps your entire operation in a single software. Field-proven for 20 years at over 400 waste management companies.
})
No more isolated tools: as the ERP system for waste companies, CONWIN brings prospect, order, dispatching, weighing, records and invoicing together in one central database.
Intuitive drag-&-drop dispatch board with route optimization, recurring orders and automatic contribution-margin calculation (CM I) – see the margin of every job instantly.
Vehicle scale with RFID/transponder recognition, IP-camera documentation and digital signature capture. Weigh-in and weigh-out run automatically – tied straight to the job.
Electronic waste verification (eANV) via the Modawi interface: sign eEN, eBGS and eÜNS, ZKS communication and register management – legally compliant under German waste law (KrWG).
Customer CRM
The CRM manages prospects, customers, delivery sites and construction projects in one central address system – with contacts, freely definable address groups plus geocoordinates and area assignment for later price finding.
Quotations, invoices, reminders and mailings are automatically added to the chronological customer history – everyone on the team sees the full record.
Assign delivery sites and points of origin to projects – so even with several sites per customer it stays traceable what was delivered and collected where.
The built-in info and follow-up system reminds you of open topics, and mailings reach selected address groups straight from the system.
Quotation, invoicing run and document digitisation interlock in CONWIN – three stations from everyday commercial work.
Quotations with status tracking from "sent" to "accepted" – prices are proposed from the customer’s conditions.
Via "quotation to delivery note", the acceptance becomes the order directly – and the quoted prices can be stored as customer-, site- or order-specific special prices with a validity date. They then apply automatically to all further orders and billing.
One run invoices all reviewed delivery notes – following the invoicing cycle and structure defined in the customer master.
Invoice or credit note is recognised automatically by the sign, and revenue account assignment runs per line item. Customers set to e-mail delivery receive their invoice in ZUGFeRD format straight from the run – you see immediately how many were sent, and delivery errors are filtered out in the invoice browser.
Third-party documents such as external weighbridge tickets are digitised via barcode – CONWIN handles the assignment to the record.
Print the barcode from CONWIN, stick it on the document, scan – done. The button on the scanner already decides whether the document is sent as an invoice attachment with the e-invoice or just filed. Document separation and assignment run fully automatically; anything unprocessed lands visibly in its own folder. Digitally signed documents from the CONWIN Sign-App – such as delivery notes from the driver or weighbridge tickets at the scale – are in the system without passing through the scanner.
Dispatching & route planning
Dispatching and route planning happen in one screen: plan container exchanges, collections and emptyings by drag and drop. Integrated container tracking shows the location and rental days of every skip, warns about missed deadlines and bills rentals automatically.
With contribution-margin calculation (CM I) you see the margin of every job instantly – including route optimization, multi-stop small-container tours and subcontractor handling.
End-to-end process
Prospects live in the CRM with a chronological history – quotations, invoices and reminders file themselves there. Prices are proposed from the customer’s conditions.
CRM & historyOne click turns the acceptance into a delivery note. In the background, CONWIN checks the credit limit against overdue open items, order blocks and duplicate risk.
Checked in the backgroundCompleted transport orders and saved weighbridge tickets automatically create delivery notes with finished invoice items – recurring orders such as monthly rentals continue themselves.
Automatic line itemsThe collective invoicing run invoices, assigns accounts and sends – then open-item management and automatic dunning with freely definable levels take over.
Through to paymentE-invoicing
With e-invoicing master data in place, CONWIN creates all outgoing invoices in ZUGFeRD format – a PDF with embedded XML structure, sent via your own SMTP server with SSL/TLS encryption.
Your stationery sits behind every document as a PDF/A-3 background – with its own sender address, subject and mail text per document type.
Documents such as weighbridge tickets or delivery notes accompany the invoice – merged, as one separate PDF or individually, configured globally or per customer.
The invoice shows when and to which address it was sent – delivery errors surface via a dedicated filter in the invoice browser.
No isolated solution
CONWIN connects to scales (incl. Pfreundt wheel-loader scales), telematics (TomTom & CONWIN), accounting (DATEV etc.), ESTOS telephony and customer portals – more than 250 established interfaces from 20 years of industry practice.
Your data stays safe: we create a daily encrypted backup in a German data center and provide an emergency system. After an outage, fire or cyber-attack you are back up and running within hours.
Master-data intelligence
CONWIN always searches from the specific to the general price condition – and automatically applies the most specific one.
Base price, price group, quantity scale, special price per customer, order or delivery site – with price history and validity dates.
Transport and disposal at one flat price, internally split cleanly across the base articles – even cascaded. The proposal comes automatically.
Area-based transport prices via postcode assignment – narrowed down to district, street and even house number where needed.
Material surcharges such as the German CO2 levy (BEHG) insert themselves into the delivery note as their own line item – as do article-level surcharges.
Revenue group plus tax key yield the ledger account – every invoice line assigns itself, optionally with automatic vehicle and facility cost centres.
Process depth
Control any number of vehicle scales – fully automatic via transponder or manual, documented by up to three IP cameras and digital signature capture. The mobile yard app handles quality control and photo documentation right at the material.
Keep vehicles and containers in view in real time. The system warns about deadline overruns, optimizes routes and keeps a complete container journal including automatic rental billing – from a single skip to the multi-stop tour.
A weighing slip automatically becomes an invoice. Store multi-level price scales, special prices and association billing (DSD, Interseroh, Zentek). Reverse-charge, dunning and subcontractor billing are built in – everything flows automatically into your accounting.
Meet the German Circular Economy Act at the push of a button: electronic register management, bidirectional ZKS communication via Modawi, and waste and material-flow balances straight from order processing.
