About Us

Invoicing Services was established in 2003 to submit electronic billing for trailer repairs.  Invoicing Services has submitted over 100,000 invoices for its clients into both the IDCS and TRIM/CTRIM systems.  After the recent switch of the Canadian National Railway to the IDCS system from the TRIM/CTRIM system, all our clients are now using the IDCS system.  Our clients have been very pleased with our understanding of the entire process, all the way from them sending their written invoices to Invoicing Services to the receipt of electronic payment to their company.
