Salesforce holds the relationship; orders, invoices, stock and the legal record usually live elsewhere. We connect it to SAP or Odoo, the data platform and government services through MuleSoft or your existing integration platform, using platform events and Change Data Capture so systems stay in step without nightly batch surprises.
For large data volumes we design for governor limits from the start: bulk APIs, asynchronous processing and selective synchronisation instead of copying everything. Our integration and API practice owns the contracts on both sides.
