  4. Needs Sorting means Amstad will match the invoice to the right job/project before Project Review.

Approver SOP

Every invoice starts in the portal before Ramp.

  1. Intake: portal forms, uploads, forwarded invoices, scans, and emails to invoices@amstadops.com all land here first.
  2. PDF extraction: the portal saves the original PDF and reads invoice number, date, amount, vendor, and possible property/job details when possible.
  3. Needs Sorting: if the job/project ID is missing or unclear, Project Managers classify it before review.
  4. Project Review: confirm vendor, job, scope/category, budget, completion reference, and duplicate status.
  5. Create for Sub: only Amstad employees with this permission can create an invoice on behalf of a subcontractor; subcontractors never see this internal tool.
  6. Approve & Send to Ramp: one click creates the Amstad cover page + original invoice PDF packet and sends it to Amstad’s internal Ramp destination.

Amstad invoice control center

All invoice paths land here first. Sort the job, review the invoice, then use one click to create the saved PDF packet and send it to Ramp.

Intake Portal form, PDF upload, invoices@amstadops.com, accounting forward, or paper scan

Messy or unknown-job invoices land in Needs Sorting before review.

Project Review Project Reviewer approves vendor, scope, budget, and job match

Monday remains the future assignment/completion source. Until then, Project Review controls the match.

Ramp handoff Internal Ramp destination

One click creates and sends one saved PDF: Amstad cover page + original invoice/scan. Destination stays hidden from subcontractors.

Create invoice for subcontractor Amstad permission

For the rare case where an Amstad employee needs to enter an invoice on behalf of a subcontractor. This section is internal only and controlled by the “Create for sub” user permission.

Internal only

Subcontractors do not see this tool. The invoice still appears in the normal queue, checks duplicates, can go to Needs Sorting, and must pass Project Review before Ramp.

Team messages & notifications

Anyone on the Amstad team can ask invoice questions, request files, or reply to subcontractor admin-only messages inside the portal.

Auto-translation concept

Messages can display original + translated copy so English/Spanish teams and subs stay aligned.

Subcontractor · Spanish original

¿Pueden confirmar cuál trabajo corresponde a esta factura?

Portal translation

Can you confirm which job this invoice belongs to?

Subcontractors

Amstad can view, edit, deactivate, remove, and segment subcontractor/vendor accounts by market and trade.

Vendor account list

Use this area to manage every vendor column: market, trade, login email, W9, direct deposit, status, and future Monday job assignment eligibility.

Amstad user control Admin only

Only Amstad users with admin access should see this area. Admins can invite users and toggle exact permissions on or off for each person.

Permission matrix

Each checkbox is its own permission. The real app would save these to the user account.
