Connect Zoho Books to envoice
Audience: Shop owner (Admin) Time: 2 minutes
If you use Zoho Books or Zoho Invoice, connect it to envoice so you can submit your Zoho documents to LHDN MyInvois directly from inside Zoho, no re-entry.
1. Open the envoice widget in Zoho
In Zoho Books, open any invoice, credit note, or debit note. In the right sidebar, open the envoice.my widget and click Sign in & Connect.

New to envoice? Click Create free account , the widget walks you through it.
2. Sign in to envoice
A popup opens on envoice.my. Sign in with Zoho, Google, GitHub, or your email and password. (If you just created your account, you are signed in already.)

envoice asks only to read the documents you submit and to write the MyInvois result (UUID, status, QR) back onto them.
3. Select your business
Choose which envoice shop to link to this Zoho organization, then click Connect Zoho Books. If you do not have a shop yet, use + Create new shop.

4. Connected
You are returned to envoice and the shop shows as connected. You can now submit Zoho documents to MyInvois from the envoice sidebar widget.

Re-connecting (Sign out, then Sign in & Connect again) is how you grant new permissions after an envoice update. Signing out keeps the connection, so you are not asked to approve again. Your existing data is preserved.
5. LHDN fields on your Zoho documents
When you connect, envoice adds a set of custom fields to your Zoho organization automatically. You do not have to create them. Most are filled by envoice; a few are optional inputs you can set when a document needs them.
Filled by envoice (on the document after submission): MyInvois UUID, QR Link, Status, and Doc Type. Credit, debit, and vendor credit notes get their own set so they do not inherit the invoice's UUID.
On your contacts (so the buyer is identified correctly): TIN, ID Type, ID Value, and SST Registration.
On your items (so each line is classified correctly): LHDN Classification, LHDN Tax Type, LHDN Tax Exemption Reason, LHDN Tariff Code, and LHDN Country of Origin. Set these on the item once and envoice picks them up on every line, even if Zoho does not copy them onto the transaction.
On the invoice (optional): LHDN Prepayment (an amount paid in advance) and LHDN Billing Start / LHDN Billing End (the billing period). Fill these only when they apply.
If envoice adds new fields in an update and you do not see them, open the envoice shop page and click Sync custom fields, or simply reconnect.
