Automate Collaborati with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Rejected invoices, every client, each morning

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each client you name, get the invoices in Rejected status on Track Invoices.

  Step 2

  Keep the invoices that were not on the last run's list.

  Step 3

  Email you the list, one section per client, with matter, invoice total and date of status change.

• Paid invoices, posted to your accounting system

  Build this

  Starts

  Every day at 18:00

  Step 1

  For each client, get the payment details of invoices that moved to Paid since the last run.

  Step 2

  Stop when there are none.

  Step 3

  Post invoice number, matter number, amount paid, date, check and PO number to your accounting webhook.

• Timekeepers waiting on client authorization

  Build this

  Starts

  Every Monday at 9:00

  Step 1

  For each client and office, check timekeeper authorization.

  Step 2

  Keep timekeepers in Pending Client Authorization or Unauthorized.

  Step 3

  Email you the list grouped by client, marking those whose status changed since the last run.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get invoice statuses” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "collaborati.net/get_invoice_statuses",
    "input": {
      "billed_to": "Acme",
      "invoice_status": "Rejected"
    }
  }'

{
  "status": "completed",
  "data": {
    "billed_to": "Acme",
    "invoices": [
      {
        "invoice_number": "INV-2026-0418",
        "matter_name": "Acme v. Globex",
        "matter_number": "M-10293",
        "date_submitted": "2026-11-03",
        "invoice_total": 18450,
        "approved_total": 0,
        "total_adjustment": 0,
        "invoice_status": "Rejected",
        "date_of_status_change": "2026-11-10"
      }
    ],
    "count": 1
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

Collaborati’s own options

Mitratech's guides for firms describe work in the browser: LEDES or manual invoices, timekeeper and rate uploads, and email notifications. They document no API for firms. Mitratech's integrations connect Collaborati to clients' own systems, such as Lawtrac. The Collaborati Use Fee is described in the License Agreement.

Signing in to Collaborati

Collaborati signs you in with your email address and a password of at least 12 characters. A unified login reaches your firm's office accounts, chosen in Select Office. With Fous you sign in once through Collaborati's own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

Paid shows only when the client shares it

An invoice reaches Paid status only if the client shares payment status. The invoice then shows Amount Paid, Date, Check and PO Number.

Each client enforces its billing guidelines

A client can require one matter per invoice or a 90-day submission window. Invoices that break its guidelines can be rejected, or charges adjusted to agreed rates.

Uploaded files are processed before submit

An upload moves from Processing Invoices to Ready to Submit, Ready to Submit with Errors, or File Error. Invoices with fatal errors are not submitted, and Waiting for Client to Accept means the client's system has not received it yet.

One login, filtered by office

A unified login combines a firm's billing offices under one Firm account. Most pages show one office at a time through Select Office; some offer All Offices.
