Vendor management can quickly become messy.

Supplier details live in Airtable. Documents arrive by email. Purchase order updates happen in spreadsheets. Someone sends a reminder in Slack. A vendor resends the same file because they do not know whether the first one was received.

If your team already uses Airtable to manage vendors, purchase orders, products, documents, or shipments, you can create a better vendor experience without moving to a separate supplier management system.

With miniExtensions, you can build a vendor portal connected to Airtable. Vendors can log in, see the records connected to them, submit onboarding information, upload documents, and update statuses without accessing your Airtable base.

What is an Airtable vendor portal?

An Airtable vendor portal is a supplier-facing interface built on top of your Airtable data.

Your internal team continues working in Airtable. Vendors use a simplified portal where they only see the information you choose to share.

A vendor portal can include:

  • Vendor profile details
  • Onboarding forms
  • Compliance documents
  • Purchase orders
  • Product submissions
  • Shipment updates
  • Invoices
  • Requests
  • Status dashboards

The portal is powered by miniExtensions Portal, while Airtable remains the database.

Why vendor portals work well with Airtable

Airtable is flexible enough to model most vendor workflows. You can create tables for suppliers, products, purchase orders, shipments, documents, and approvals.

The missing piece is usually external access.

You want vendors to update the data that belongs to them, but you do not want to invite every supplier into your Airtable base. You also do not want vendors editing internal fields, seeing other suppliers’ records, or getting confused by your internal workflow.

miniExtensions solves this by giving vendors a controlled interface.

Vendors do not need Airtable accounts. They do not need miniExtensions accounts. They only need access to the portal link or login link you share with them.

Example Airtable setup

A vendor portal might use these tables:

  • Vendors
  • Purchase Orders
  • Products
  • Shipments
  • Compliance Documents
  • Invoices
  • Requests
  • Contacts

The Vendors table is usually the portal users table. Each vendor record stores login information and profile details.

Other tables should link back to the vendor. For example:

  • Each purchase order links to a vendor
  • Each shipment links to a vendor
  • Each compliance document links to a vendor
  • Each product submission links to a vendor
  • Each invoice links to a vendor

When the vendor logs in, the portal can show the records connected to that vendor.

Vendor onboarding workflow

A vendor portal is especially useful for onboarding.

Instead of collecting information through emails and attachments, you can give new vendors a portal where they complete the required steps.

For example, a vendor onboarding portal might include:

  • Company profile
  • Primary contact
  • Tax information
  • Banking or payment details
  • Insurance documents
  • Certificates
  • Product categories
  • Shipping preferences
  • Required agreements

You can use the Portal profile feature to let vendors update their own vendor record. You decide which fields are visible and which fields are editable. For the initial application, a miniExtensions can also be used. This is explained further below.

For documents, vendors can upload files through forms connected to Airtable attachment fields. Your team can then review those records internally and update approval status in Airtable.

Purchase orders and shipment updates

Once a vendor is onboarded, the same portal can support ongoing operations.

A vendor might log in to see:

  • Open purchase orders
  • Purchase order details
  • Required ship dates
  • Shipment status
  • Tracking numbers
  • Product records
  • Open requests
  • Invoice status

You can decide whether vendors can only view these records or also update specific fields.

For example, vendors might be allowed to update:

  • Estimated ship date
  • Tracking number
  • Shipment status
  • Quantity confirmed
  • Attachment or invoice file
  • Notes for your procurement team

But they should not edit internal fields like:

  • Internal approval status
  • Buyer notes
  • Margin
  • Internal priority
  • Payment approval

Child forms let you control the create and edit experience for each table.

Use views to separate open, pending, and completed work

Vendor portals are easier to use when records are grouped by status.

You can create views such as:

  • Open purchase orders
  • Waiting on vendor
  • Documents needed
  • Pending review
  • Approved documents
  • Completed shipments
  • Paid invoices

In miniExtensions, you can expose the views that make sense for vendors.

You can also limit editing based on conditions. For example, once a compliance document is approved, the vendor may still be able to view it but not edit it. Or once a purchase order is closed, you can prevent updates through the portal.

Show different access by vendor type

Not every vendor needs the same portal.

A supplier of physical goods may need purchase orders, products, and shipment updates. A contractor may need onboarding documents, work orders, and invoices. A strategic vendor may need a larger dashboard.

miniExtensions supports conditional tables and conditional views based on fields in the users table. You can use this to show different portal sections based on:

  • Vendor type
  • Approval status
  • Region
  • Category
  • Contract status
  • Internal owner
  • Active or inactive status

This helps you manage multiple vendor workflows in one portal instead of creating separate portals for every supplier category.

Sharing the portal with vendors

You can share a Portal in several ways:

  • Copy the portal URL and send it by email
  • Generate a magic link for a vendor
  • Email login links to users in your vendors table
  • Embed the portal on your website
  • Use a custom URL

For vendors, magic links or email login links are often the easiest path because they reduce friction and make it clear which vendor record they are accessing.

Build a vendor portal on top of Airtable

If your vendor workflow already lives in Airtable, a portal can make that workflow easier for suppliers and easier for your team.

Vendors get one place to onboard, upload files, view open items, and send updates. Your team keeps Airtable as the source of truth. Access stays controlled through the portal configuration.

Start with miniExtensions Portal and turn your Airtable vendor base into a supplier portal your vendors can actually use.

How to set this up in miniExtensions

Create a vendors users table.

    In Airtable, create a Vendors or Suppliers table. This will be the Portal users table.

    Useful fields include:

    • Vendor name
    • Contact name
    • Email address
    • Vendor type
    • Approval status
    • Region
    • Compliance status
    • Active vendor checkbox
    • Payment terms

    Use a unique email field as the main login field.

    Link vendor records to the tables they need.

      Create or prepare the operational tables vendors should access:

      • Purchase Orders
      • Shipments
      • Products
      • Compliance Documents
      • Invoices
      • Requests

      Each table should include a linked record field pointing to the Vendors users table.

      This linked field is required for the Portal to show each vendor only their own records.

      Use a Form for initial vendor applications.

        Before vendors have portal access, create a miniExtensions Form for new vendor applications.

        The form can create records in the Vendors table and collect:

        • Company name
        • Contact info
        • Vendor category
        • Tax details
        • Required documents
        • Notes or application details

        Set the vendor’s approval status to something like Pending Review.

        Your internal team can review the vendor in Airtable before giving portal access, or you could set all necessary fields to required in the form, and redirect the user to the portal after submitting the initial form.

        Create the vendor Portal.

          In miniExtensions, go to Create Extension and choose Portal.

          Select the Airtable base, then choose the first data table (e.g. Products) and the field linking each order to the appropriate customer (e.g. Vendor).

          Because this is a Portal, login is enabled automatically. Configure login fields in Users & Login.

          Restrict portal access to approved vendors.

            If only approved vendors should access the portal, go to:

            Users & Login -> Conditional Login

            Turn on Conditional Login and add a condition such as:

            • Approval Status is Approved
            • Active Vendor is checked

            If a vendor no longer meets the condition, they will be logged out when they load the portal.

            Add additional vendor-facing tables.

              Go to the Portal Tables section and add any additional tables vendors need:

              • Purchase Orders
              • Shipments
              • Products
              • Compliance Documents
              • Invoices
              • Requests

              Each table will only show records linked to the logged-in venodr by default. This ensures one vendor cannot see another vendor’s purchase orders, documents, shipments, or invoices.

              Configure purchase order and shipment views.

                Create practical views such as:

                • Open Purchase Orders
                • Waiting on Vendor
                • Ready to Ship
                • Shipped
                • Completed
                • Closed

                For shipment updates, expose only fields vendors should edit, such as:

                • Estimated ship date
                • Tracking number
                • Shipment status
                • Vendor notes
                • Attachment

                Keep internal fields hidden or read-only.

                Add document uploads.

                  For compliance documents, allow vendors to create new records in the Compliance Documents table.

                  In the child form, include fields such as:

                  • Document type
                  • Expiration date
                  • Attachment
                  • Notes

                  Set Review Status to a default value such as Pending. New records created within the portal will automatically be linked to the logged-in user.

                  Use Profile for vendor account updates.

                    Go to Profile and enable Show logged in profile.

                    Configure the profile child form so vendors can update safe profile fields:

                    • Company name
                    • Contact name
                    • Email
                    • Phone
                    • Address
                    • Payment contact
                    • Shipping contact

                    Hide internal fields such as approval status, internal owner, risk notes, and review notes.

                    Show different sections by vendor type.

                      Use conditional tables or conditional views to show different portal sections based on fields in the Vendors users table.

                      Examples:

                      • Product vendors see Products and Shipments
                      • Contractors see Work Requests
                      • Approved vendors see Purchase Orders
                      • Pending vendors only see onboarding documents
                      • Vendors in one region see region-specific resources

                      Configure this in Conditional Table or Conditional View.

                      Share the vendor portal.

                        Use the Portal Share section to:

                        • Copy the portal URL
                        • Generate magic links
                        • Email login links to vendors
                        • Embed the portal on a private vendor page
                        • Configure a custom URL

                        Test with a sample vendor record before sharing broadly. Confirm the vendor only sees their own purchase orders, documents, shipments, and requests.
