About this gig

Whatever tool you use, I can connect it to your CRM or ERP. No more copying data by hand, no more exports and manual imports, and no more lost leads from records that never made it across.


I build custom integrations and sync services that connect any program to your CRM or ERP, so data flows automatically and reliably.


Systems I connect to:

  • CRM: HubSpot, Salesforce, Pipedrive, Zoho, CentralStationCRM
  • ERP: SAP, DATEV, Lexware, weclapp, Odoo, Microsoft Dynamics 365
  • Plus your shop, your app, spreadsheets, or anything with a REST API or database

What I build:

  • One way or two way sync between your CRM/ERP and any other program
  • Custom API connectors, middleware, and extension programs
  • Field mapping, deduplication, and proper error handling
  • Scheduled or near real time syncing with retry logic
  • Clean logging and alerts, so you always see exactly what happened


I handle the messy parts (auth, rate limits, pagination, edge cases) so your team stops doing manual data entry and starts trusting the numbers.

Message me with the program you want connected and what data should move. I will send you a clear plan, a timeline, and a fixed price before you order.
