Keep invoicing in Excel.
We handle Fawtara.

Yes. GoRoute Connect for Excel adds a button to Excel that validates every invoice against the Oman Fawtara rules (PINT OM v1.0.1), sends it to your customer over the Peppol network, and files the tax data document with the Oman Tax Authority. You do not leave the spreadsheet.

No. GoRoute Connect adds a button to the Excel you already use. You keep typing invoices the way you do today; the button handles the compliance, sending and tax reporting.

Open GoRoute once in a workbook, then save that workbook. Excel stores the add-in reference inside the file, so every time you open it GoRoute loads by itself with the button on the Home tab and the pane ready. Keep one workbook — call it Invoices — and open that to invoice. A brand-new blank workbook will not have it, because the reference lives in the file rather than in Excel.

Download the installer for Windows or Mac and run it. The Mac installer is signed and notarised by Apple, so it opens without any warning; Windows shows a “Windows protected your PC” message for new programs — click More info, then Run anyway. If you would rather not install anything, open your workbook at excel.office.com and add GoRoute there; a free Microsoft account is enough. If your company has a Microsoft 365 administrator, they can deploy it once for everyone.

Excel 2016 and every version since, on Windows and Mac, whether you pay monthly for Microsoft 365 or bought Excel outright — plus Excel in a browser. Excel 2019 and 2016 use an older browser engine, so GoRoute ships a second version of itself for them and loads it automatically. Excel 2013 and older cannot run add-ins at all; those users fill in the GoRoute template and upload it instead.

A simplified tax invoice is the document for a sale to a consumer who is not VAT-registered. Technically it is a normal invoice (type code 380) whose Oman transaction type marks it as simplified, issued against the official substitute participant because the buyer has no Peppol identifier. In GoRoute Connect you simply leave the customer VAT number blank and it is issued that way, with the Fawtara QR code the customer can verify.

The Oman Tax Authority allows 24 hours to report the tax data document for a consumer (B2C) sale. GoRoute files it for you when you press Send, so an invoice showing 'awaiting the Tax Authority' inside that window is normal rather than stuck.

Yes. Use the same invoice number on each row and they become one invoice with several lines. You only fill in the customer, date and type on the FIRST row of that invoice — leave those cells blank on the rows below and they use the same ones. If you do type a different customer against the same invoice number, GoRoute stops and says so, since two customers' goods cannot share one tax document.

No. GoRoute is a certified Peppol Access Point and an accredited Oman Fawtara service provider, so your invoices reach the network through us. There is nothing for you to certify, host or maintain.

Yes. Choose the document type in the sheet. Credit and debit notes reference the original document properly, and self-billed invoices and credit notes ride Oman's separate self-billing profile automatically.

Yes. One button switches the pane and the column headings to Arabic, with the layout mirrored right-to-left. Column headings are recognised in either language, so a workbook shared between Arabic and English speaking colleagues keeps working for both.

GoRoute offers data residency in Oman for customers who require it, so invoice data does not leave the country. See the Oman data residency page for the detail.

The add-in itself is free to download and install. You need a GoRoute account to send invoices; book a demo and we will size a plan against how many invoices you issue.

You are told in plain language before anything is sent — for example that a customer's VAT number should start with OM followed by ten digits. Nothing is transmitted until every invoice passes the Oman rules.

Within a sheet, no: sent rows are locked and the button disables while sending. Across different workbooks, take care — reusing an invoice number you have already issued creates a second, separate document. Invoice numbers must be unique and sequential for your business, so give every invoice its own number and never reuse one.

On Windows open Settings, then Apps, then Installed apps, find GoRoute Connect for Excel and choose Uninstall. On a Mac open your Applications folder and double-click Uninstall GoRoute Connect for Excel. Then close Excel and open it again. Your invoices are unaffected — everything already sent stays on your dashboard and your spreadsheets are untouched.
