Custom Payroll Software Development

Pay elements configured to your specific compensation model -- base salary, hourly pay, shift premiums, overtime rates, on-call allowances, commission tranches, bonus triggers, and any other pay components your employment contracts specify. Calculation logic for each pay element defined in the engine rather than applied as a manual adjustment after the platform runs: the shift differential that applies only to the night shift roster, the commission calculation that requires revenue data from a separate system before it can be finalised, the bonus that is pro-rated for new starters and leavers in the relevant period. Pay group management for businesses with employees on different pay frequencies, different pay calendars, or different benefit schemes, with the correct rules applying to each group without manual intervention.

Statutory deduction calculation for the employment jurisdictions in scope -- income tax, national insurance or social security contributions, pension auto-enrolment, student loan repayments, and any other statutory deductions that apply to each of your legal entities and their employees. Tax table and threshold updates applied as part of the platform maintenance when legislation changes, so the payroll engine stays current without a developer engagement for every tax year. Employer cost calculation alongside the employee deduction -- the employer's national insurance or payroll tax contribution, the employer pension contribution, and any other employer-side statutory costs -- feeding the general ledger posting so the total payroll cost is reflected accurately in the finance system. Statutory reporting outputs in the format required by each tax authority in scope -- RTI for the UK, FPS and EPS submissions, or the equivalent submission format for other jurisdictions.

Integration with your HRMS so that employee data changes that affect payroll -- new hires, leavers, salary changes, employment type changes, benefit enrolment changes -- flow to the payroll engine without requiring the payroll team to re-enter information that HR has already recorded. The integration runs on a defined schedule or is triggered by events in the HRMS, with a reconciliation check before each pay run to flag discrepancies between the HRMS and payroll records before processing. Time and attendance integration for businesses paying hourly employees or shift workers -- the approved hours from the time and attendance system used as the input to the payroll calculation rather than hours entered manually by the payroll team. Absence data integration where sick pay, parental leave, and other statutory absence payments are calculated from the absence records in the HRMS rather than from manual records.

Payroll processing for multiple legal entities from a single platform, with the payroll rules for each entity -- its employment laws, its tax jurisdiction, its statutory deduction regime, and its pension or benefits scheme -- maintained separately and applied correctly to each entity's employees. Consolidated payroll reporting across all entities for group HR and finance, with entity-level drill-down for the payroll administrator responsible for each entity. Currency handling for businesses paying employees in different currencies, with the exchange rate applied at the point of payroll processing and the general ledger posting in the entity's functional currency. Jurisdiction-specific statutory reporting generated from the same payroll run without requiring a separate process for each jurisdiction.

General ledger posting from the payroll run to your finance system -- salary costs, employer tax costs, pension costs, and benefit costs allocated to the correct cost centres, departments, and accounts without manual journal entry by the finance team. Integration with Xero, Sage, QuickBooks, NetSuite, or a custom general ledger, with the posting format matched to your chart of accounts and cost centre structure. Payroll accrual posting for businesses that accrue payroll costs mid-period and reverse the accrual at the actual pay date. Bank file generation in the format required by your bank or payment processor for bulk payment to employee accounts, with the payment file produced from the approved payroll run without manual reformatting. Reconciliation report matching the payroll journal to the bank file and the statutory submissions so the finance team can close the payroll period with confidence.

Payroll summary report at the individual, cost centre, department, and entity level -- the report that payroll and finance review before approving each pay run. Variance report comparing the current pay run to the prior period with explanations for each movement above the configured threshold, so the payroll team can confirm that differences are expected rather than errors. Payslip generation and distribution -- digital payslips accessible to employees through the self-service portal or delivered by email, with a batch generation option for large payroll runs. Historical payroll data retained for the full statutory retention period with query tools for employee payment history, statutory deduction history, and year-end reporting. Audit log recording every change to employee pay records, who made the change, and when it was made -- the audit trail required for payroll compliance and internal audit.
