Who should I contact regarding billing/timesheet/vendor matters?

Last updated: September 21, 2026

Summary: For billing, invoice, and vendor-payment matters, email accountsreceivable@ascen.com. For timesheets and workers, contact your staffing agency. Not sure? Email support@ascen.com.

  • Billing, invoices, and vendor/payment matters — email accountsreceivable@ascen.com (incorrect charges, payment terms, remittance, payment confirmations).

  • Workers and assignments — contact your staffing partner. They manage placements, schedules and who is on site.

    A timesheet that looks wrong — if you have not approved it yet, your staffing partner can correct it. Once a timesheet has been approved — or once it has been invoiced or paid — only Ascen can change it: email support@ascen.com with the worker, the date and what it should say.

  • Anything else, or if you're not sure — email support@ascen.com.
