Pegasus Opera 3 SQL SE — Financials
Know exactly where your business stands,
right now
Opera 3 Financials gives UK businesses a single, integrated view of their financial position - sales ledger, purchase ledger, nominal ledger, cashbook and credit management all working together in real time. No rekeying. No chasing spreadsheets. No end-of-month guesswork. MTD-compliant VAT submissions to HMRC built in.
Real-time cashflow visibility
See what you're owed, what you owe, and what's in the bank - updated the moment a transaction is posted. No waiting for month-end reports to know where you stand.
Credit control that actually works
The Credit Management Centre automates chasing, flags overdue accounts and gives your team a single dashboard of every outstanding debt - so you reduce debtor days without adding headcount.
MTD-compliant from day one
VAT returns submitted directly to HMRC from within Opera 3. No third-party bridging software, no manual uploads - just compliant submissions every time, with a full audit trail.

The current climate
When cash is tight, your finance system
needs to be ahead of the problem
UK business insolvencies in 2025 remained well above pre-pandemic levels. 90% of companies experienced late payments. HMRC enforcement is tighter. Costs are up. In that environment, running a finance system that's a week behind reality isn't just inefficient — it's a risk. Opera 3 gives you a real-time picture of where you stand, and the tools to act on it before problems become crises.

Real-time cashflow — Sales & Purchase Ledger
Every transaction posts immediately. You see what you're owed, what you owe and what's in the bank right now — not as of last Monday's report. When margins are tight, that difference matters.
Control when payables hit — Purchase Invoice Register
Invoices sit in the PIR until authorised before posting to your Purchase Ledger. You control exactly when payables are committed — useful when you're managing cashflow timing carefully.
Daily bank visibility — Cashbook
Reconcile against your bank statement with full transactional drilldown. Save a partial reconciliation and come back to it. Set up recurring entries so nothing gets missed. Know your actual bank position every day, not at month end.
Post without closing — Open Period Accounting
Post transactions into any open period across the last, current or next three financial years without locking prior periods. Under pressure, the last thing you need is a month-end lock causing delays or errors cascading through your accounts.
Management accounts on demand — XRL & Reporting
Live Opera 3 data pulled directly into Excel via Pegasus XRL. P&L, balance sheet, budget vs actuals — refreshed at the click of a button. When your bank, board or accountant needs figures fast, you're not scrambling to build a report manually.
Budget vs actuals — Nominal Ledger
Set budgets at account, cost centre and department level. Run full percentage variance analysis at any point in the period — not just at year end. Spot where you're overspending before it becomes a problem, not after.

Optional add-on module — worth knowing about
Credit Management Centre —
built inside Opera 3, not bolted on
The Credit Management Centre is an optional Opera 3 module that gives your finance team a single, consolidated view of every outstanding customer debt — with automated chasing workflows, dispute tracking and real-time dashboards. Unlike Sage and Xero, where automated credit management means paying for a third-party tool on top of your accounting subscription, CMC lives natively inside Opera 3. No separate login. No data sync. No extra vendor.
What Credit Management Centre does
- Single real-time dashboard — all outstanding customer debt in one view, not scattered across reports
- Up to nine levels of automated debtor correspondence — letters and emails triggered by debt age, without manual chasing
- Promised payment tracking — log what customers commit to and flag immediately when they don't deliver
- Real-time graphs showing total debt, promised payments and overdue amounts at a glance
- Dispute logging with reason codes — track unresolved issues without losing sight of the underlying debt
- Retrospective debtors report — rerun your aged debt position at any past date for board packs, audits or bank conversations
How it compares to Sage & Xero
| Feature | Sage 50 | Xero | Opera 3 + CMC |
|---|---|---|---|
| Aged debtors report | |||
| Account stop / credit limits | |||
| Automated chasing workflows | |||
| Consolidated debt dashboard | |||
| Promised payment tracking | |||
| Retrospective debt reporting | |||
| Needs a third-party subscription |
Sage 50 and Xero require third-party tools such as Credit Hound or Chaser for automated credit management — additional cost and subscriptions on top of your accounting software. Opera 3 CMC is a purchasable module within your existing Opera 3 system — same platform, same data, no third-party dependency.
