Managing vendor relationships through email works until you have more than 10 active vendors. Zoho Books 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 purchase orders, 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. Setup takes under 20 minutes and cuts down on back-and-forth significantly for businesses with 10 or more active vendors. When you first turn the portal on, Zoho Books prompts you to confirm your organisation name, which is what vendors will see in the portal URL.

To add more contacts at a vendor, navigate to Purchases > Vendors and open the vendor record, then scroll to the Contact Persons section and add or confirm the email address of the person who should receive portal access. From the vendor record, use the three-dot menu and choose Send Portal Invite. Zoho Books sends an email with a one-time activation link, and the vendor sets their own password during first login.

Back in Settings > Vendor Portal, set visibility permissions for what vendors can see. You can choose to show purchase orders only, or also expose outstanding bills, payment history, and statements. Once you have sent an invite, log in with the vendor’s own credentials to confirm the correct documents are visible and the layout matches what you expect.

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, so check that the contact person on the PO matches the one who was sent the invite.

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.

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. For Indian businesses this is especially useful during GST reconciliation: when a vendor uploads an invoice through the portal, you can cross-check the GSTIN, invoice number, and tax amounts against your purchase register before booking the bill, which reduces the risk of input tax credit mismatches in GSTR-2B.

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

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

Frequently Asked Questions

Is the Vendor Portal free in Zoho Books?
Included in Professional and higher plans at no extra charge. No per-vendor fee. Vendors do not need a Zoho account. The portal is not included in the Standard plan; if you are on Standard and need vendor portal access, an upgrade to Professional (Rs 1,499 per month) is required.
Can vendors see other vendors’ data?
No. Each vendor sees only their own transactions. The portal is completely isolated per vendor.
Can I restrict which POs a vendor sees?
Vendors see all transactions on their vendor profile. Create separate profiles for different contacts if you need visibility restrictions.
Does the portal work on mobile?
Yes. The responsive web application works on smartphones and tablets with no separate app required.
Can a vendor upload invoices directly through the portal?
Yes. Vendors can upload invoices as PDF or image files against open purchase orders. Once uploaded, your accounts team receives a notification in Zoho Books and can review and approve the bill. The uploaded document is stored alongside the transaction record.
How many vendor contacts can access the portal?
You can invite multiple contact persons per vendor. Each contact person gets their own login. There is no hard limit on the number of vendor portal users, though each vendor organisation can only access their own data; contacts from one vendor cannot see another vendor’s purchase orders or payments.
