Pegasus Opera 3 is a UK mid-market ERP with integrated accounting, payroll, and CRM modules built on Microsoft SQL Server, designed for established SMBs and growing businesses that need on-premises or private-cloud control.
In its favor
Why people choose Opera 3
The signal that keeps Opera 3 on the shortlist. Sourced from G2, Capterra, and customer scoping calls.
Modular ERP covering accounting, payroll, stock, and CRM in a single integrated system, eliminating the need for separate disconnected applications in small finance teams.
Strong UK payroll compliance including RTI/FPS and EPS filing with HMRC, making it a stable choice for businesses subject to UK payroll legislation.
SQL Server edition provides enterprise-grade data integrity with referential checks, transaction rollback, and health-validator before any migration proceeds.
Multi-currency and multi-company support at a mid-market price point, suitable for UK businesses with overseas subsidiaries or trading relationships.
On-premises or private-cloud deployment option appeals to businesses in regulated industries that require data residency control rather than SaaS.
Customer service ratings are consistently below competitors (3.8/10 on Capterra), with users reporting slow response times and difficulty reaching knowledgeable support staff.
Steep learning curve for non-accountants, particularly around multi-company setups, inter-company transactions, and the report generator's customisation layer.
Frequent product updates and version migrations cause friction, especially for customers on the Visual FoxPro edition who face a mandatory upgrade path to SQL SE.
Limited ecosystem compared to global platforms — fewer third-party integrations, no marketplace, and bespoke API work required for modern data pipelines.
Modern SaaS alternatives like Xero and QuickBooks offer faster onboarding, automatic updates, and lower upfront cost, prompting smaller customers to migrate.

What gets migrated
Opera 3 object support
Object-by-object support for Opera 3 migrations. Per-pair details surface during scoping.
Chart of Accounts (Nominal Ledger)
Fully supportedNominal Ledger accounts map directly as GL accounts. Opera 3 uses account codes with cost-centre tagging; we preserve the full code hierarchy and centre assignments during export.
Customers and Suppliers
Fully supportedSales Ledger and Purchase Ledger contacts export via CSV with full address, payment terms, credit limits, and multi-currency settings intact.
Sales Orders and Purchase Orders
Fully supportedOrder headers and line items export with pricing, discounts, delivery addresses, and status flags. We preserve the order-to-invoice linkage chain.
Invoices and Credit Notes
Fully supportedSales and Purchase invoices with header totals and detail lines. Opera 3 enforces that invoice totals = sum of lines, so we validate this relationship before loading.
Stock/Inventory Items
Mapping requiredStock codes, descriptions, bin locations, reorder levels, and BOM structures export cleanly, but customer-specific product variants (from OPUS add-on) may require additional field mapping to the destination.
Employees
Mapping requiredEmployee records export via CSV including bank details, start/end dates, and P45 data. RTI FPS XML files contain tax submission records; EPS files hold employer payment summaries. Email and mobile fields live in separate Worker Details exports.
Fixed Assets
Fully supportedFixed asset registers with acquisition dates, cost, depreciation method, NBV, and disposal history export as structured records.
Projects and Project Costing
Fully supportedProject cost codes and phase-level tracking export with labour, purchase, and expense allocations linked to the Nominal Ledger.
Multi-Currency Transactions
Mapping requiredCurrency codes, exchange rates, and transactional amounts in foreign currencies export. We preserve the rate used at transaction time and flag where the destination currency must match a supported currency pair.
Bank/Cash Transactions
Fully supportedCashbook entries with bank reconciliation references export including payment references, dates, and matched invoice links.
Tax Codes and EC VAT
Mapping requiredVAT rates and EC VAT transaction flags export, but UK MTD-specific tax period mappings require validation against the destination's tax configuration.
Document Attachments (PDFs)
Mapping requiredPDFs for invoices, statements, and remittance advices are stored as binary files in Opera 3's document folders. We extract and attach them to the corresponding transaction record in the destination, where the file naming convention matches the document reference.
Multi-Company Structures
Mapping requiredOpera 3 supports inter-company transactions and consolidated reporting across multiple company codes. We extract each company as a separate entity and map inter-company debtor/creditor balances to the destination's inter-company setup.
Custom Properties and User-Defined Fields
Not in this platformCustom fields added via the OPUS add-on or bespoke modifications to the Visual FoxPro schema are not standardised and may require manual field-by-field review. We do not automatically migrate bespoke fields; these are flagged for manual handling after scoping.
CRM Contacts and Activities
Mapping requiredBuilt-in CRM module stores contacts, companies, and activity logs. Activities are text-based notes rather than structured events; we map them to the destination's activity/timeline format where supported.
