Outsourcing payroll feels like the safe option — until you tally up the bureau fees, the delay every time you need a corrected payslip, the lack of visibility into your own payroll data, and the painful disconnect between your payroll provider and your finance system. For businesses running Dynamics 365 Business Central, the better answer is to bring payroll in-house with software that lives natively inside the same environment your finance team already works in.

Sirius Payroll 365 is HMRC-recognised payroll software built as a fully native extension of Dynamics 365 Business Central. There is no integration to maintain, no duplicate data entry between systems, and no separate vendor to manage. Your payroll runs inside Business Central, posts automatically to your general ledger, and gives your finance team full visibility and control — all for just £1.00 per employee per month.

Sirius Payroll 365 is developed by Sirius App, part of the Dogma Group — specialists in Microsoft Dynamics 365 extensions — and is available on Microsoft AppSource. Finsys Apps is a specialist implementation and support partner for Sirius Payroll 365, deploying and configuring the solution within your Business Central environment, migrating your existing payroll data, and ensuring your team is fully trained and confident from day one.

Whether you are a small UK business looking for an affordable first in-house payroll solution, or a growing organisation that needs multi-company or multi-currency payroll capability, Sirius Payroll 365 scales with you — with no IT expertise required to get started.

Manual payroll processing is a significant source of error, compliance risk, and wasted finance team time. Sirius Payroll 365 automates the complete payroll run — from salary calculations and tax deductions through to pension contributions, sickness, overtime, leave, and contracted hours — so your payroll team spends less time on data entry and more time on exception handling and reporting.

Every pay period, Sirius Payroll 365 calculates PAYE, National Insurance, statutory payments, and pension contributions automatically, applying the latest HMRC tax tables and legislation without manual intervention. Payslips are generated, previewed, and distributed to employees as password-encrypted emails — with the ability to make adjustments before finalising, ensuring accuracy before anything is committed or submitted.

Staying compliant with HMRC is non-negotiable — and the cost of getting it wrong, in penalties and corrections, quickly outweighs any saving from a cheaper payroll solution. Sirius Payroll 365 is HMRC-recognised and handles all your statutory submissions directly through HMRC’s secure gateway, from Real Time Information (RTI) filings every pay period to full year-end reporting.

P60 and P11D submissions are automated — no manual form-filling, no separate HMRC software, no risk of missed deadlines. The system is updated automatically when HMRC changes tax rates, National Insurance thresholds, or legislative requirements, so your payroll team does not need to track changes manually or worry about running a payroll on outdated rates.

Because Sirius Payroll 365 runs natively inside Dynamics 365 Business Central, there is no integration layer to configure or maintain. Payroll journals post automatically to your chart of accounts at the end of every pay run, with cost centre and department coding applied according to your Business Central structure. Your finance team sees payroll in their general ledger instantly — no waiting for exports, imports, or reconciliation between separate systems.

For organisations also running Dynamics 365 Human Resources, Sirius Payroll 365 integrates directly — pulling employee records, tracking work hours, and ensuring payroll calculations reflect the current state of your workforce without any duplicate data entry. The result is a single source of truth across HR, payroll, and finance.

Sirius Connect 365 is the employee self-service companion to Sirius Payroll 365 — a secure, cloud-based portal that gives your employees 24/7 access to their payslips and payroll documents without needing to contact HR or finance. At just £0.50 per employee per month, it eliminates the steady stream of payslip requests that consume your team’s time and gives employees the instant access they expect.

Employees log in via secure email-based authentication and see a personalised dashboard showing their payroll documents — payslips, P60s, and any other payroll communications — available to view and download at any time, from any device. Data is retrieved in real time from Sirius Payroll 365 and Business Central, so there is no separate data store to maintain and payslips are always current.
