What's inside

The detail behind every pay run.

Screens from Towse Payroll, shown with sample clients. Names and figures are illustrative.

01 · Monthly checks

Check every run against last month.

Each net pay sits beside the previous one. Open a person to see which pay line moved, and every record change since the last locked run, with who made it.

02 · Lock and audit

Locked means locked.

Finalizing freezes every figure. Unlocking needs a reason and goes on the record, and frozen figures only change when you choose to recalculate. Once a period is past its filing deadline, only an administrator can unlock it.

03 · Secure forms and portals

Hours, starters and changes come to you.

Clients send hours through a single-use link. New starters and bank changes arrive the same way, encrypted, and nothing touches the payroll until you apply it. Client admins and employees each get their own portal.

04 · Payslips and T14s

Payslips that arrive protected.

Email each payslip or year-end T14 as a PDF locked with the employee's own password, or publish it to their portal. You review recipients first, and every send is logged.

05 · Bank files and T35

Payment files that check themselves.

Built from locked net pay. Missing or invalid bank details are flagged by name before you download, with the T35 remittance ready alongside.

06 · Client take-on

Move a client over mid-year.

Year-to-date opening balances from the previous provider, each tied to the report it came from.

Also inside

  • Salary grades and uplifts

    Grade scales, annual increments and backdated uplifts with back pay.

  • Pension schemes

    Occupational, personal and salary sacrifice, with banded employee rates.

  • Tax years and pay calendars

    Tax weeks and months, client pay dates and year-end closure.

  • Employee documents

    Passports and certificates stored encrypted, with expiry warnings.

  • Reports

    Monthly, pension and custom reports, as PDF or CSV.

  • Team and access

    Staff, client admins and employees, each limited to what they need.

  • Backup and restore

    Export the whole account, and preview conflicts before restoring.

How it works

Four steps. Every client, every month.

Each pay period runs in the same order, so you always know what's done, what's waiting and what changed.

  1. 01Calculated · 4 of 4

    Run

    Salaries, hours and pensions calculate for everyone in one go. Change a figure and it recalculates on the spot.

  2. 02Review · still editable

    Check

    Every net pay sits beside last month's. Each difference traces back to the pay line that caused it.

  3. 03Finalized

    Lock

    Finalizing freezes the figures. They only move again if an admin unlocks the period, and that goes on the record.

  4. 04Sent · 4 payslips

    Send

    Payslips go to each employee, with the T35 remittance and the bank payment file ready alongside.

Built for the Island

Made for the Isle of Man, not adapted to it.

ITIP, per period
Non-cumulative, with free pay and the standard band from the published tables.
Manx NI
Weekly and monthly thresholds, earnings tracked at each band, and category C by certificate.
State Pension Age
Worked out from date of birth using the full published timetable.
T14 and T35
The T35 remittance each month and the T14 electronic file at year end.
Yearly rates
Published and reviewed for each tax year. New rates never change a locked period.

Security

Your clients' payroll, kept to the right people.

Built to a written security standard, with isolation tests run on every change.

  • Field-level encryption

    NI numbers, passports, bank details and document passwords are encrypted with AES-256-GCM before they are stored.

  • Every reveal on the record

    Showing an encrypted field, downloading a document or opening a shared link writes an audit entry.

  • Sign in with an emailed code

    No passwords to reuse or leak. Sensitive changes ask you to verify again.

  • Strict separation

    Each practice sees only its own clients. Client admins and employees see only their own records.

  • Links that expire

    Form links work once and show no personal data. Document links expire and can be revoked.

  • Hosted in the EU

    Payroll data is stored in the EU West region, with account backups you can restore.
