How to Set Up the Vendor Portal in Zoho Books

Managing vendor relationships through email works until you have more than 10 active vendors. Zoho Books accounting platform Vendor Portal gives each vendor a self-service login to view POs, submit invoices, track payment status, and upload documents without calling your accounts team.

What the Vendor Portal Does

Each vendor accesses a dedicated web interface with their own credentials to: view all Zoho Books purchase order managements, accept or decline POs, submit invoices against accepted POs, track payment status, view account statements, and upload supporting documents.

Enabling the Portal

Go to Settings > Preferences > Vendor Portal and enable it. Customise with your company logo. To invite vendors, open a vendor profile and click Enable Portal Access with the vendor’s contact email.

Vendor Invoice Submission

Submitted invoices appear in your Zoho Books inbox as vendor bills awaiting approval. Review, match against the PO, and approve or reject. This replaces the manual process of receiving invoice PDFs by email.

Payment Visibility

Vendors see real-time payment status: which invoices are approved, scheduled, or paid. This transparency reduces payment enquiry calls by 60% to 80%.

Document Management

Vendors upload delivery challans, test reports, warranty cards against specific POs. Documents are stored against the transaction, creating a complete procurement file for auditors.

Step-by-Step: Setting Up the Vendor Portal

The Vendor Portal in Zoho Books gives your suppliers a dedicated login to view purchase orders, upload invoices, and check payment status without needing to call or email your accounts team. Setup takes under 20 minutes and cuts down on back-and-forth significantly for businesses with 10 or more active vendors.

1. Enable the portal: In Zoho Books, go to Settings > Vendor Portal and toggle it on. You will be prompted to confirm your organisation name, which vendors will see in the portal URL.
2. Add vendor contacts: Navigate to Purchases > Vendors and open any vendor record. Scroll to the Contact Persons section. Add or confirm the email address of the person at the vendor who should receive portal access.
3. Send the invite: Inside the vendor record, click the three-dot menu and choose Send Portal Invite. Zoho Books sends an email with a one-time activation link. The vendor sets their own password during first login.
4. Configure what vendors can see: Back in Settings > Vendor Portal, set visibility permissions. You can choose to show purchase orders only, or also expose outstanding bills, payment history, and statements.
5. Test vendor access: Log in with the vendor’s credentials to confirm the correct documents are visible and the layout matches what you expect.

Once the portal is active, vendors can submit invoices directly by uploading PDF or Excel files against open purchase orders. Your team receives a notification in Zoho Books and can approve or query the invoice without leaving the platform.

GST and Documentation Requirements in the Portal

For Indian businesses, the vendor portal becomes particularly useful during GST reconciliation. When vendors upload their invoices through the portal, you can cross-check the GSTIN, invoice number, and tax amounts against your own purchase register before booking the bill. This reduces the risk of input tax credit mismatches in GSTR-2B.

You can also configure the portal to require vendors to attach their GST invoices (with IRN and QR code for e-invoiced suppliers) before submission is accepted. This gives your accounts team a consistent document pack for every vendor transaction, which is especially useful during GST audits.

For vendors covered under TDS Section 194C or 194J, the portal displays net-of-TDS payment amounts once bills are approved. Vendors can download TDS certificates (Form 16A data) directly when your Zoho Books account is configured for TDS tracking.

Common Setup Issues and How to Fix Them

The most common issue during setup is the portal invite email landing in the vendor’s spam folder. If a vendor says they did not receive the invite, resend it from the vendor record and ask them to check junk mail. The invite link expires after 7 days.

A second issue is vendors seeing an empty portal after logging in. This usually happens when the purchase orders were created under a different contact person than the one with portal access. Check that the contact person in the PO matches the one who was sent the invite.

Frequently Asked Questions

If you have a large vendor list and want to activate the portal for all vendors at once rather than one by one, use the Bulk Invite option. Go to Purchases > Vendors, select multiple vendor records using the checkboxes, and choose Send Portal Invite from the bulk action menu. This sends invitations to all selected vendors simultaneously and saves time during initial rollout.
