TotallySum keeps your books current in Omani rials. TotallySum Connect connects any ERP to Oman's e-invoicing network. Use either one, or run both on the same platform.
Public launch · 20 November 2026
Cloud accounting for Omani businesses: invoices, bills, bank feeds, VAT and reports in one ledger, to the baisa.
One connection between SAP, Oracle or any ERP and the national e-invoicing network. We validate, exchange and report. You keep invoicing the way you do today.
Global tools adapt to Oman later. TotallySum starts here: OMR to the baisa, 5% VAT on every line, and e-invoicing accredited by the Oman Tax Authority.
TotallyTech is an accredited Fawtara service provider, so your e-invoices go through an approved route from day one.
Hosted in-country, with every invoice archived and searchable for ten years.
Run your books on TotallySum with e-invoicing built in, or keep your ERP and add Connect. One provider either way.
SAP, Oracle, QuickBooks, Zoho and Tally, plus API, SDKs, SFTP and bulk upload for any other system.
Our consultants and engineers are in Muscat, from readiness assessment and ERP mapping through to go-live.
Packages from OMR 25 a month, published on our site. Unlimited branches on every Connect package.

OpenPeppolFull memberYou enter it once and it shows up everywhere it belongs: on the invoice, in the bank match and on the VAT return.
Each morning, transactions are matched against what you invoiced and what you owe. You confirm the rest with a click.
Oman's 5% VAT is tracked on every line, so the return builds itself as you go.
Quotes, invoices and credit notes in OMR with three decimals, sent straight from the ledger.
Profit and loss, balance sheet and cash flow, up to the last transaction.
Turn it on and every invoice you issue goes out as a compliant e-invoice. No second system.
Your ERP or TotallySum creates the invoice exactly as it does today.
TotallySum Connect checks format, VAT and mandatory fields before anything leaves.
The e-invoice reaches your buyer over the Peppol network.
Tax data is reported to the Oman Tax Authority, and the status flows back to your ERP.
