Built to order
The decision to move from Zoho to Odoo is usually made on functionality — manufacturing, deeper inventory routing, field service, or simply the wish to run one database instead of a suite of connected apps. That decision is cheap. The cutover is not. Zoho Books holds your posted ledger, your open receivables and payables, your tax history and your bank reconciliation state. Zoho CRM holds pipeline, activity history, notes and attachments that the sales team measures itself against every week. Both have to land in Odoo with the numbers intact, inside a freeze window, without losing the audit trail that ties a payment to an invoice.
The usual failure is a partial cutover. Contacts and products come across because they are the easy objects. Open invoices are re-keyed by hand, so the ageing is wrong and the first month-end takes a fortnight. Leads arrive without owner, stage or original creation date, so the pipeline report is meaningless and the reps go back to spreadsheets. Attachments and email history stay behind in Zoho, which means the old subscription cannot actually be cancelled and you now pay for two systems while trusting neither.
This toolkit is a build-to-order engagement. Nothing is pre-built and there is no instant download. ECOSIRE inspects your live Zoho data, builds the extraction, mapping and load routines for it, proves them against a staging Odoo database, and executes the production cutover with a reconciliation pack that both sides sign. Typical lead time is two to four weeks from an accepted quote.
Zoho CRM is extracted through its Bulk Read API across Leads, Contacts, Accounts, Deals, Activities including calls, tasks and events, Notes, Attachments and any custom modules you have added, with pagination and resume so a large tenant does not fail halfway. Zoho Books is extracted through REST API v3 across the Chart of Accounts, Contacts, Items, Invoices, Bills, Credit Notes, Vendor Credits, Customer and Vendor Payments, Expenses, Manual Journals, Sales Orders, Purchase Orders, Taxes and Bank Accounts. Extraction runs from scheduled Deluge functions with OAuth scopes limited to read access, and the output lands in a staging application built in Zoho Creator. Delta pulls keyed on last-modified timestamps mean the final cutover extract only carries what changed since the dry run, which is what keeps the freeze window short.
Every Zoho field is mapped explicitly to an Odoo field, and you approve that map as a workbook before any loading is built. Contacts and Accounts become res.partner with parent and child relationships preserved. Items become product.template and product.product with the right unit of measure. Deals and Leads become crm.lead with stage, sales team, salesperson, expected revenue, probability, expected closing date, lost reason and original creation date intact. Invoices, bills, credit notes and manual journals become account.move with balanced account.move.line records. Payments become account.payment reconciled against the documents they settled, instead of arriving as unallocated cash for your accountant to match by hand. Taxes, payment terms, currencies and journals map to account.tax, account.payment.term, res.currency and account.journal rather than silently falling back to Odoo defaults.
Loading runs through the Odoo external API over XML-RPC or JSON-RPC, in batches sized to your server, with every record written against a stable external identifier registered in ir.model.data. That single design choice is what makes a corrective re-load safe: a second run updates the record it created the first time instead of creating a duplicate. Failures are captured with the full payload and the server error message, so a rejected batch is diagnosable rather than mysterious. No server-side Odoo code is required, which keeps the approach viable on hosted Odoo deployments where custom modules are restricted.
Most businesses take opening balances only: trial balance posted as a dated journal, with open receivables and payables loaded as individual documents so ageing works from day one, and closed history left readable in the retained Zoho tenant or in an export. Where statutory or audit requirements demand it, we load full posted history into account.move instead. The mode is a scoping decision with a clear price difference, and we will tell you plainly when the cheaper option is sufficient.
Activity history and notes are rebuilt as mail.message and mail.activity records against the correct Odoo record, so a salesperson opening an account sees the same timeline they saw last week. Attachments are transferred into ir.attachment against the matching record, with a manifest listing anything that could not be retrieved rather than a silent gap. Picklist values, custom fields and user accounts are mapped explicitly, including what happens to records owned by users who are not moving across.
Each run produces a dual reconciliation pack: trial balance compared line by line, AR and AP ageing compared bucket by bucket, open pipeline value compared by stage, and record counts compared per object with the rejected rows itemised. The production cutover is not scheduled until the staging run produces a pack you are willing to sign.
Businesses that have outgrown the Zoho suite and have already chosen Odoo, and that carry enough financial and CRM history to make a manual re-key unrealistic. It fits companies with multi-currency trading, a real receivables ledger, or a sales team whose forecast depends on historical stage and close-date data. It also fits Odoo implementation partners who want the data migration handled as a separate, reconciled workstream so their configuration project is not derailed by it.
Scoping call. We review your Zoho Books and Zoho CRM tenants, object volumes, custom fields, currencies and tax setup, plus the Odoo version, hosting model and how far its configuration has progressed.
Fixed quote. A written scope naming every object in and out, the financial mode, the reconciliation criteria and a price. Nothing starts until you accept it.
Build. Extractors, mapping configuration and loaders are built against your real extract, not sample data.
Install in test. The full load runs into a staging Odoo database. You review the pipeline, the ageing and the reconciliation pack, and we iterate until it is clean.
Production cutover. An agreed freeze window, a delta extract, the production load, then the signed reconciliation pack handed over.
You get a support window covering any defect traced to the migration, a rollback and re-run runbook explaining how the external identifiers make a corrective load safe, and a handover session for finance and sales operations. All extraction code stays in your Zoho account and the loaders are delivered to your repository, so nothing about the migration is locked behind us.
A short call to confirm the workflow, your platform version and where the integration boundaries sit.
You receive a written scope and a fixed price. Nothing is built until you approve it.
We develop against a copy of your configuration and test it there. Typically two to four weeks.
We install on your instance, hand over the source, and support it for twelve months.
Is signing off a suite change while remaining answerable for the statutory numbers on both sides of the cutover date. Gets a trial balance and ageing comparison between the two systems before production is loaded, plus a documented decision on whether history is posted or archived.
Knows the forecast dies the moment leads land in the new system without stage, owner or original creation date. The pipeline is rebuilt on crm.lead with those fields intact and the activity timeline reconstructed, so week-one reporting matches what the team saw in Zoho.
Is configuring chart of accounts, journals, taxes and workflows and cannot also absorb an open-ended data migration. Data extraction, mapping, loading and reconciliation run as a separate workstream with its own quote, staging run and sign-off criteria.
