Omega One · Accounting Suite

Your books. Your VAT.
Your e-invoices.

Omega One is cloud accounting built for the UAE. Invoices, purchases, banking, stock, point of sale and payroll flow into one set of books — and your VAT-201 return and FTA Audit File come straight out of them, ready to check and file.

Built for the questions that
come at quarter end.

Most accounting software treats VAT as a report you run at the end. Omega One treats it as part of every document — so the answers are already there when you need them.

"Where does this box 1b figure come from?"
Every figure traces to its invoices
Click any box of the return to see the documents behind it, and check the return against your VAT ledgers before you file.
"Someone changed an invoice after we filed."
Posted means final
Posted documents can't be edited or deleted. Mistakes are corrected with a credit note or reversal, and closed or filed periods stay locked.
"The auditor wants the full history."
A complete audit trail
Every change records who, when, and the values before and after — in a tamper-evident log that follows a document from entry to the VAT return.
"Our invoice numbers have gaps."
Gap-free numbering
Tax invoices take their number only when posted, after the checks pass. Drafts never use up a number.
"Which rate applied on that date?"
Effective-dated tax codes
Tax codes and rates carry start dates and are kept forever, so past documents are always read with the rules of their day.
"We buy in dollars and sell in dirhams."
Multi-currency, reported in AED
Foreign-currency documents keep both amounts. AED values are rounded line by line and fixed when the document is posted.

Everything a UAE business runs on,
in one set of books.

Each module posts to the same ledgers, so reports, VAT and stock always agree with each other. Start with what you need and switch on the rest as you grow.

VAT handled on every line,
not reworked at quarter end.

Omega One applies the right tax code as each line is entered — from the item, then the customer or supplier — and records the emirate of supply. The return and the audit file are built from those lines, so there's nothing to re-key.

01
VAT-201 return
Supplies by emirate, reverse charge, zero-rated, exempt, imports, intra-GCC and corrections — calculated, reconciled to the VAT ledgers and exported as XML or XLSX.
02
FTA Audit File (FAF)
Company, purchase, supply and general ledger data for any period, including earlier years. Checked before release; every file is stored unchanged and every download is logged.
03
Reverse charge & imports
Output and input VAT are posted together in the same period. Customs permit numbers and import VAT are captured on the document.
04
Partial exemption
Recoverable and blocked input VAT handled separately; the non-recoverable share goes to cost automatically using your recovery percentage.
05
Corrections done right
Earlier-period corrections ask which period they belong to, and those above AED 10,000 are flagged for voluntary disclosure instead.
06
Checks before posting
TRN format, mandatory tax fields, duplicate supplier invoices and VAT arithmetic are checked before a document can be posted.

01
Accounting firm
Your team works across every client from one login, with a single view of what's due.
02
Client
Each client sees only its own data. Its staff can enter documents while you review and file.
03
Companies
A client with several companies switches between them, and lists can show all companies at once.

One system for every client
you look after.

Omega One is built for accounting and tax firms as much as for the businesses they serve. Your staff do the day-to-day bookkeeping and VAT work for all of your clients, without juggling separate files or logins.

Access is controlled by role: full access for your team, entry rights for client staff, and read-only access for reviewers and auditors. Users can be limited to specific companies.

When you need help, Omega's support team can look into an issue through a logged, read-only support session — so you always know who saw what.

Switch without starting over.

Whatever you use today — another accounting package or spreadsheets — our team moves your data into Omega One for you, so you start with your real balances, customers and stock, not a blank screen.

01

Bring your masters

Customers, suppliers, chart of accounts, stock items, units and warehouses are imported from your existing system or a spreadsheet.

02

Bring your balances

Opening balances, the year's transactions and stock on hand are loaded, so your reports are complete from day one.

03

Compare side by side

Check the trial balance, P&L, balance sheet and stock valuation against your old system before you switch.

04

Go live

Pick a go-live date. From then on Omega One is your system of record, with its own controls and audit trail.

Frequently asked.

Is Omega One cloud software? Where is our data kept?

Yes. Omega One runs in the cloud on Oracle technology, so there's nothing to install and you can work from anywhere. We'll confirm the hosting region and our backup arrangements during your demo.

Can we file our VAT return from Omega One?

Omega One calculates your VAT-201 return, reconciles it to your books and produces the return file for you to upload. Filing the return locks the period so its figures can't change afterwards.

What happens if we make a mistake on a posted invoice?

Posted documents are final, as UAE VAT records should be. You correct them with a credit note, debit note or reversing entry — one click on the original document creates it — and both stay in the audit trail.

Do we have to use every module?

No. Many businesses start with sales, purchases and VAT, then add inventory, POS or payroll later. Everything posts to the same books, so adding a module never means re-entering data.

We're an accounting firm. How does pricing work for our clients?

We offer plans for individual businesses and for firms managing several clients. Book a demo and we'll put together a quote for your client base.

Do you provide training and support?

Yes. We help with setup and migration, train your team, and support you afterwards. Firms and resellers can also get training for their own staff.
