HR · Recruitment · UK Payroll · Self-service
One platform for your whole workforce, from vacancy to payslip.
Tessera brings recruitment, HR, payroll, absence, learning and reporting into one system for UK organisations — single company or a whole group — with automation you control and a team you can reach.
No card needed · every module included during the trial · priced per employee per month
What a payroll month looks like
- Timesheets and overtime approved by managers on their phones
- Inputs collected automatically; the holiday-pay uplift on regular overtime calculated for you
- PAYE, NI, pensions and statutory payments calculated and reconciled against last month
- Payroll approved, BACS file produced, payslips published to the app
- FPS sent to HMRC; pension file sent to the provider; journals posted to finance
Calculations tested against HMRC's published 2026-27 test data (2,390 checks, every one within a penny). RTI submissions accepted by HMRC's test service.
Everything in one place
Nine modules on one database, so a new starter created in recruitment is already in payroll, absence, learning and the org chart.
People & HR
Employee records, contracts and salary history, documents, qualifications, organisation structure across many companies, positions, succession and workforce planning, TUPE.
Recruitment & onboarding
Vacancy approval, careers site, CV parsing and matching, interviews with Teams, scorecards, offers with e-signature, right-to-work checks, digital onboarding that creates the employee record.
UK payroll
Monthly and weekly payroll, PAYE, NI, student loans, pensions and auto-enrolment, SSP/SMP/SPP, court orders, salary sacrifice, holiday pay on overtime, RTI, BACS, payslips, P60s and year end.
Absence & wellbeing
Leave and entitlements, sickness with fit notes and return-to-work, Bradford factor and triggers, family leave, occupational health referrals, wellbeing alerts and pulse surveys.
Self-service
Employees see payslips, book leave, report absence, claim expenses with receipt capture and sign documents; managers approve, see their team calendar and analytics. Works as a mobile app.
Learning & performance
Training catalogue and matrix, mandatory training with expiry alerts, certificates, objectives, development plans, appraisals, competencies and 360° feedback.
Reporting & analytics
Headcount, turnover, absence, diversity, vacancy and payroll dashboards, a report designer, scheduled distribution, data exports and a live Power BI data feed.
Administration
Roles and permissions per company, Microsoft Entra ID single sign-on and MFA, audit trail, workflow builder, form builder, policy library, branding, integrations.
Assistant & automation
An assistant that answers from your own data, and processes you can run in Manual, Assisted or Autonomous mode inside guardrails you set — every automatic action logged and reversible.
Up and running in days, not months
Create your workspace
Sign up with your organisation name and email. Your isolated workspace, with UK pay elements, leave types, workflows and standard reports already configured, is ready in about a minute.
Bring your people in
Add employees by hand, import from a spreadsheet, or use the migration toolkit to load HR and payroll history from your current system, with validation and reconciliation reports.
Run it alongside, then switch
Run a parallel payroll against your current provider, compare to the penny, then go live. Every module is free for 30 days; choose a plan when you are ready.
Your own space, in the UK
Each organisation's data lives in its own database schema, isolated by PostgreSQL itself, hosted on our own UK infrastructure. Daily backups. Export everything at any time.
Built for compliance
UK GDPR data processing agreement included, ICO registered, encryption in transit and at rest, MFA, role-based access per company, and a full audit trail of every action — including automatic ones.
AI that stays inside
Candidate matching, the assistant and workforce insights run on our own models and infrastructure. No CV or payslip is sent to an outside AI provider, and your data is never used for training.
Groups, housing associations and larger employers
Multi-company groups with separate PAYE references, TUPE transfers, SHPS and NEST pensions, Microsoft 365 and Power BI integration, data migration from your current system with parallel payroll runs, and the choice of our hosted service, your own Azure tenant or an on-premises installation.
- Multi-company, one database
- Entra ID single sign-on
- Power BI live data feed
- Teams interview scheduling
- Migration toolkit and parallel runs
- Dedicated support from the people who built it
