Automate Taulia 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.

• Invoices that changed status, every customer

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each customer you name, check the statuses of your invoices in My Invoices.

  Step 2

  Keep the invoices whose status changed since the last run, such as to Incomplete, Rejected or Approved.

  Step 3

  Email you the list, one section per customer, with the status reason where there is one.

• Released payments, posted to your accounting system

  Build this

  Starts

  Every day at 18:00

  Step 1

  For each customer, get the payments in My Payments with a pay date since yesterday.

  Step 2

  Stop when there are none.

  Step 3

  Post payment reference, pay date, amount and the invoices paid to your accounting system's webhook.

• Invoices with early payment available, weekly

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  For each customer, check My Invoices for invoices in Early Payment Available status.

  Step 2

  Keep the ones that were not on the last run.

  Step 3

  Email you the list by customer, so someone decides which ones to request early payment for.

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 “Check 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": "portal.taulia.com/check_invoice_statuses",
    "input": {
      "customer": "Acme",
      "invoice_numbers": [
        "INV-20431",
        "INV-20447",
        "INV-20452"
      ]
    }
  }'

{
  "status": "completed",
  "data": {
    "customer": "Acme",
    "invoices": [
      {
        "invoice_number": "INV-20431",
        "status": "Approved",
        "status_reason": null
      }
    ],
    "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.

Taulia’s own options

Taulia's supplier help centre describes no API for reading your invoices or payments. For sending invoices in bulk it offers eFile, which takes EDI, EDIFACT, XML or CSV files after a setup with Taulia, and eSend for PDF invoices. Payment reports download from the portal as XML, PDF or CSV.

Signing in to Taulia

Taulia signs you in with your email address and password. Two-factor authentication can be turned on for a user, or company-wide for every user of an account. With Fous you sign in once through Taulia's own sign-in with your own account. The login is sealed with AES-256, and code and AI agents never see it.

Worth knowing

Your customer decides what you see

Each customer chooses which invoice statuses its suppliers see, so a status may not exist for every customer. The payables process itself belongs to your customer's accounts payable group.

Invoices sent outside Taulia appear later

An invoice you sent another way shows in My Invoices only once your customer has entered it in its accounting system and flagged it for display in your account.

Two platforms, two sign-ins

Taulia has a North American platform (login.taulia.com) and a European one (login.eu.taulia.com). Your credentials work only on the platform where your customer's account exists.

Payments come from the customer

Remittance details are available as soon as your customer releases a payment. Taulia does not generate the payments, and My Payments may not be available in every portal.
