Zoho Integration

Documents into Zoho Books, records in sync with Zoho CRM, workflows triggered from either side.

What moves

What flows between Zoho and PTAS AI

Documents and master data come in from Books and CRM. Bills, orders, attachments and status go out. Zoho stays the system your team works in; the typing stops.

Zoho Books

Vendors and customers, purchase orders, bills, vendor payments, chart of accounts

Zoho CRM

Accounts, contacts and deals, and sales orders where you use them

The documents

Supplier bills, customer purchase orders, expense receipts, credit notes

PTAS AI

Bills created from the documents

One bill per document, lines coded to your accounts, GST treatment and place of supply set, the PDF attached, written only after approval.

Records in step across Books and CRM

A customer order read from a PDF lands against the right CRM account. A vendor saved in Books is checked before its first bill.

A trail on both sides

The Zoho record ID sits on the FinSuite record; the source document sits on the bill or the order in Zoho.

Zoho is a planning example here, not a packaged connector. Which Zoho apps you run, which edition and data centre, and who approves what are confirmed in discovery.

Integration methods

How Zoho can be connected

Four ways in. For most Zoho organisations the API is the obvious one; the harder question is which side owns each record.

Native

What Zoho does itself

Zoho Books has its own scanning for bills and receipts, and syncs contacts with Zoho CRM through Zoho integration. Where that sync is on, we write to one side and let Zoho carry the record across. We list nothing on Zoho Marketplace, and nothing on this page is a packaged connector.

API

Zoho Books and Zoho CRM REST APIs

REST over HTTPS, authorised through OAuth by your Zoho admin, with scopes limited to the modules the workflow needs, called on the data centre your organisation is hosted in. Bills, vendors, purchase orders and payments in Books; accounts and deals in CRM. The route we would expect to propose, confirmed in discovery.

File

Imports, for a backlog

Zoho Books imports bills and contacts from CSV or spreadsheet files. Useful for loading a backlog or a quarter of historic bills once. We would not run a live payables process on file imports where the API is available.

Custom

Zoho Flow, Deluge, or several organisations

Teams that already run Zoho Flow or Deluge functions can route the traffic through them, so the logic stays where their admin looks. Several Books organisations, one per GSTIN or country, or Zoho as one of three systems in the flow, need orchestration on top.

The route for your organisation is confirmed in discovery, against the Zoho apps and edition you run. For most teams it is the API: Zoho Books for the ledger side, Zoho CRM for the customer side, and a webhook from a Zoho workflow rule wherever a change in Zoho should start work here. Zoho limits API calls per organisation per day by plan, so the sync is sized to your volume and a month-end batch is spread across the day. Zoho also runs separate data centres for India, the US, Europe and other regions, and the connection is made to the one your organisation lives in.

Each record carries both referencesBoth sidesOne trail
Either side Work can start from a document arriving, or from a change someone makes in Zoho. The trail is the same either way.

Illustrative example. A trigger from Zoho exists only where your Zoho admin creates the workflow rule, so nothing here runs without a decision on your side.

What we would not automate. A bill is not created in Zoho Books until the vendor contact exists with its GSTIN and GST treatment, the coding passed validation and someone with the right limit approved it. We would not write a customer into both Books and CRM when Zoho already syncs them, and we would not create vendors from a document alone. Your team creates them; we check them.

Field mapping

Where each finance object lands in Zoho

The mapping is agreed before build and kept per Books organisation. This is the starting point we bring to the assessment.

Finance objectIn Zoho Books or Zoho CRM
Vendor A contact of type vendor in Zoho Books, with GST treatment, GSTIN, place of supply, payment terms and bank details. We match on GSTIN and bank account before proposing a new vendor; a name alone is never enough. Your team creates the vendor; a workflow rule can send it to FinSuite for checks before its first bill.
Customer order A customer purchase order, read by the Purchase Order Agent, becomes a sales order in Zoho Books against the customer, or an update on the account in Zoho CRM, depending on where your sales team works. The account is found by GSTIN or account number.
Purchase order A purchase order in Zoho Books, matched line by line against the bill and referenced from it. Where POs are raised in another system, the PO stays in FinSuite and is referenced on the bill.
Goods receipt Where receipts are recorded in Zoho, in the editions that track inventory, we read the quantity received. Otherwise a delivery note read by DocPro gives FinSuite the third leg of the match, attached to the bill as evidence.
Invoice A bill with item or account lines, each coded to your chart of accounts, HSN or SAC on each line and the PDF attached. Saved as a draft where approval runs in Zoho Books; created open where FinSuite approved it.
Tax GST treatment and source and destination of supply on the bill, so Zoho Books applies IGST, or CGST and SGST, as it expects. Elsewhere, the VAT or sales tax of your edition. We check the document first and hold a mismatch or a reverse-charge purchase for review. The tax itself is left for Zoho Books to compute.
Payment status Vendor payments applied to the bill, read back by webhook from a Zoho Books workflow rule where your admin sets one up, or on a schedule where not.

Linked both ways The ERP document carries a link back to the invoice image it came from.

Field mapping is yours to define. Entries are validated against it before they reach the ERP, not rejected by it afterwards.

Security of the connection

What protects the link to your Zoho organisation

Four controls, each one visible to your Zoho admin. None of them depends on trusting us.

OAuth, granted by your Zoho admin

Your admin authorises the connection on Zoho's consent screen, with scopes limited to the modules the workflow uses, and can revoke it from Zoho at any time. We hold no Zoho password. Tokens are stored encrypted.

One organisation at a time

Each Zoho Books organisation is authorised and mapped separately, with its own GSTIN, chart of accounts and tax setup. A bill goes only to the organisation whose GSTIN is on the document.

Every write logged with its evidence

Each bill or order we create records the document it came from, who approved it and the record ID Zoho returned. A rejected write goes to a person with the message Zoho gave.

A test organisation first

The mapping is tried on a test organisation with a copy of your chart and contacts, and goes live after your team has seen the bills.

FAQ

Questions Zoho teams ask

Do you work with Zoho Books only, or the rest of Zoho too?

Zoho Books and Zoho CRM are the two we plan around: Books for bills, vendors and payments, CRM for customer accounts and orders. Zoho Inventory, Expense and Creator can come into scope where a workflow touches them. Which apps and which routes apply is confirmed in discovery.

Zoho already syncs Books and CRM. Will you write to both?

No. Where the Zoho sync is on, we write to the side that owns the record and let Zoho carry it across. Two systems writing the same contact is how duplicates start, and they are tedious to merge afterwards.

Will bills appear in Zoho Books before they are approved?

Only as drafts, and only if approval runs in Zoho Books. Then we save the bill as a draft and leave approval to Books. If approval runs in FinSuite, the bill is created once it is approved. One place approves, never both.

We run one Zoho Books organisation for India and another abroad. Is that two integrations?

One integration, one authorisation and one mapping per organisation. The Indian organisation carries GSTIN, GST treatment and place of supply; the other carries its own VAT or sales tax. The review queue is shared, with the organisation as a dimension.

Is this an extension on Zoho Marketplace?

No. The connection is authorised privately for your organisation. We do not claim a Marketplace listing, a certification or a partnership with Zoho, and we would rather build it to your chart of accounts than ship something generic.
