A Zoho Books and Zoho CRM extension that turns your Omani invoices into signed, schema-valid e-invoices and files them with the tax authority. Built to order for your org after a scoping call and fixed quote. Built to order by ECOSIRE for Zoho One (build-to-order) — indicative price from $999.00 USD; request a quote for a scoped proposal.
Your finance team raises invoices in Zoho Books, emails a PDF, and books the receipt. Under an e-invoicing mandate that PDF stops being the tax document. The Oman Tax Authority programme replaces it with a structured electronic document that has to be produced in a prescribed schema, carry a digital signature and a machine-readable code, be transmitted to the authority platform, and be kept together with whatever the platform sends back. An invoice the authority has never seen is not an invoice - it is a printout.
Zoho Books has no Oman e-invoicing localisation. There is no field on the Invoice record for an authority reference, nowhere to keep the returned code, no queue for documents that were rejected, and nothing that stops a salesperson emailing a customer a document that was never submitted. The Oman edition gives you VAT rates, a VATIN field on Contacts and Arabic-capable templates. It does not give you clearance.
The usual workarounds break the same thing in three different ways. Exporting invoices to a spreadsheet and re-keying them into a portal puts a manual, unlogged step between your ledger and your tax position, and it collapses the first time you issue a credit note against a submitted invoice. Moving billing out of Zoho Books into a separate compliance product splits your receivables across two systems and two versions of the truth. Renting a black-box middleware account bills you per document indefinitely and leaves you unable to answer the only question that matters during an assessment: what exactly did we send, and when. What you need is for Zoho Books to remain the system of record while compliance happens underneath it.
We build a bridge that lives inside your own Zoho org. Nothing about your billing process changes on the surface: your team still raises an invoice in Zoho Books, from a Zoho CRM deal or a Zoho Inventory sales order, using your numbering series and your templates. Underneath, the bridge takes over the moment the document is issued.
A Deluge custom function reads the Invoice, Credit Note or Debit Note straight from the Zoho Books record - line items, tax rates, tax groups, discounts, contact registration details, currency and exchange rate - and serialises it into the XML schema published by the authority. It is generated from the record, not scraped from a rendered PDF, so the electronic document and the ledger entry cannot drift apart. Your Zoho Books Tax Rates and Tax Groups are mapped once, during the build, to the authority tax category codes, so standard-rated, zero-rated, exempt, export and reverse-charge supplies each land on the correct code instead of being flattened into one.
Deluge cannot produce a certificate-backed signature on its own, so the signing step runs as a small function on Zoho Catalyst that holds the key material and returns a signed payload. Transmission uses the channel and credentials your business is entitled to use, and that channel is confirmed with you during scoping rather than assumed. Every call, request body and response is written to an append-only log with the Zoho Books invoice id attached, so a document can be reconstructed later without guesswork.
Custom fields are added to the Zoho Books Invoice module: submission status, authority reference, document hash, machine-readable code payload and response timestamp. Because they are real fields they are filterable in list views, usable in Zoho Books custom reports, and visible to anyone opening the invoice. Your invoice PDF template gets the code merged in as a placeholder field so printed and emailed copies carry it. A Sigma-packaged widget adds explicit Submit and Re-submit actions for the cases where automation should not decide on its own.
Platforms go down and documents get rejected, and the design assumes that rather than being surprised by it. A Zoho Creator application holds the retry queue and the dead-letter register; scheduled Deluge functions handle backoff, duplicate suppression and manual replay. Zoho Flow fans a failure out to a Zoho Cliq channel and to the accounts-receivable owner by email, so a rejection is discovered the same day instead of at month end.
Everything sits in software you already pay for. Zoho Books holds the documents and the status fields. Zoho CRM surfaces submission state on the related Account and Deal so sales can see a blocked invoice before chasing payment. Zoho Creator runs the operations console. Zoho Flow carries the alerts. Zoho Catalyst runs the signing function. Authentication is an org-scoped OAuth connection created through Zoho Connections against the Zoho Books API v3 with refresh-token rotation, not a personal access token pasted into a script that stops working the day its owner leaves the company.
Groups running more than one Zoho Books Organization are handled as a first-class case: each organization keeps its own registration number, credentials and numbering series, and the console shows them side by side.
Omani companies already standardised on Zoho Books that intend to stay there - trading and distribution businesses, contractors, professional services firms, and multi-entity groups with an Omani company alongside other GCC entities. It is equally aimed at the accounting firm or in-house IT lead who will be asked, months later, to explain exactly what was filed against a given invoice number and to produce the evidence.
Nothing here is pre-built and there is no download. The sequence is deliberate.
1. Scoping call. We go through your Zoho Books organizations, plan and API limits, your document types, your tax rate configuration, your numbering series, the registration details held on your Contacts, and which transmission channel applies to you. 2. Fixed quote. You receive a written scope and a fixed price before any code exists. If the scope changes later, the quote changes in writing before work continues. 3. Build. Development happens against a test Zoho Books organization using your real document shapes with masked data. 4. Install in test. The bridge is installed into your test organization and a full document set - a standard invoice, a credit note, a foreign-currency sale, an exempt supply - is put through end to end. You sign off on evidence, not on a demo. 5. Production install and cutover. Custom fields, workflow rules, connections and template changes are applied to your live organization, with a documented rollback for each step. 6. Support window. A defined period of defect fixes after go-live, with an agreed response path.
Typical lead time is one working week from signed quote, driven mostly by how quickly credentials and test access come back from your side.
We are not a tax authority, an accredited service provider, or a replacement for your tax advisor. We do not certify that your business is compliant. We build the mechanism that carries your documents, configured to the specification current at the time of the build, and we tell you plainly which parts of the regime are outside the software. Mandates get amended: schema versions change, fields are added, timetables move. That is exactly why the handover includes source code you own and a documented update path, and why schema changes published during the support window are handled as scoped work rather than pretended away.
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.
Nous installons sur votre instance, vous remettons le code source et incluons deux semaines d'assistance après la mise en production. Les défauts du code que nous livrons sont corrigés gratuitement.
Closes the month in Zoho Books and is now accountable for documents that must exist in the tax authority platform, not just in the mailbox of a customer. This bridge means the submission status is a field on the invoice they already open, so unfiled documents are found by a list-view filter rather than by an assessment letter.
Runs several Zoho Books organizations and refuses to add a black-box service that nobody internally can audit or hand over. Getting the Deluge functions, the Catalyst signing service and the connection configuration as owned source means the group can maintain, review and extend it without a permanent dependency.
Has to reconcile what the client invoiced against what was actually filed, often months later and under time pressure. The append-only submission log and the per-invoice authority reference turn that reconciliation into a report instead of an investigation.
