How does this connect to our accounting and ERP software?

Once a work order is signed off by the customer, our backend immediately creates a draft or finalized sales invoice in your ERP (Exact Online, SnelStart, Moneybird, or AFAS) with exact line items, VAT, and hourly rates.

Why is a one-time build cheaper than renting Bouw7 or Simplicate?

A 15-person installation firm easily pays €8,000–€15,000 every single year in per-seat software licenses. With Aergent, you make a single sprint investment and own the software permanently with zero per-user seat taxes.

Software for Installers & Contractors. Zero Monthly Seat Taxes.

Stop paying €50+ per month for every technician in your team. We build custom digital work order apps, calculation engines, and ERP sync pipelines that you own 100% permanently.

The 3-Step Construction Workflow

Designed for technicians on the road and project managers in the office. Zero double-entry of data.

In the Field

The technician views customer details, navigates to the address, selects used parts from a barcode/dropdown catalog, and has the customer sign on glass.

2. Real-Time Material & Hour Reconciliation

Office Automation

Back-office administrators see completed jobs immediately. Pricing margins and extra hours are calculated automatically based on your tariff tables.

3. 1-Click Invoice Sync to Exact / SnelStart

Zero Double Entry

No manual copying of paper slips. The system automatically creates a sales invoice and emails the PDF work order to the client, cutting days off your payment cycle.

03 / Questions
