Codeeo delivers payroll software development in Birmingham for employers whose pay rules live on the factory floor, the building site and the depot as much as in the office. We build systems that turn clock data and overtime rules into weekly or four-weekly pay, file RTI returns to HMRC, assess pension duties, process court order deductions, create BACS files and put payslips in each worker's pocket. The aim is a pay run your team can close on time without a stack of manual adjustments.
Birmingham clients work with us remotely. Codeeo has no office in the city; our team of 80+ sits in Dubai, Riyadh and Karachi, and every workshop on pay rules, every demo and every parallel run review is held by video call.

Capabilities
Birmingham's economy still leans heavily on making and moving things. Engineering firms and automotive suppliers across the city and the wider West Midlands run early, late and night shifts with premiums that differ by plant. Contractors working on major schemes such as the HS2 station at Curzon Street pay operatives directly while also paying subcontractors under the Construction Industry Scheme. Distribution businesses along the M6 and M42 run weekly pay for drivers and warehouse teams. Alongside them sit the banks, law firms and accountants of the Colmore Business District and Brindleyplace, paid monthly on salaried contracts.
Many employers here have both worlds under one company: a monthly payroll for office staff and a weekly one for the floor. Packaged software copes with that up to a point, then pushes the difficult parts into spreadsheets. We build the parts it cannot do well, starting with time data and pay frequencies, and connect everything to HMRC, your pension scheme and your bank. Smaller firms count too: a workshop in the Jewellery Quarter with a handful of craftspeople on piece rates has the same filing duties as a large plant, and often less time to spare for them.
Clocking terminals and attendance apps feed approved hours into payroll, where rounding rules, paid breaks, shift premiums, overtime multipliers and call-out payments are applied exactly as your agreements set them. Supervisors at each Birmingham site approve their own team before cut-off, and exceptions such as missing clock-outs are listed for correction.
Gross pay comes from rules, not from a supervisor's calculator.
Each workforce group runs on its own calendar, and the system handles the tax week numbering that comes with it, including the extra week 53 or week 54 payment that arises in some years. Monthly office staff and weekly operatives can share a company without sharing a pay run.
Every frequency runs from one system with the correct tax periods.
For contractors, subcontractor payments are kept separate from employee pay. The system stores verification results, applies the deduction rate HMRC confirms for each subcontractor, issues payment and deduction statements, and prepares the monthly CIS return, while employees on the same project go through PAYE and RTI as normal.
One finance team handles both without mixing the two schemes.
Attachment of earnings orders, council tax attachments, child maintenance deduction orders and student loan notices are entered with their protected earnings and priority rules. The software calculates each deduction every period, records what was paid over and to whom, and stops the order when it is discharged.
Court and agency deductions are taken correctly and in the right order.
Tax codes, including S codes for drivers or engineers who live in Scotland while reporting to a Midlands depot, are applied from HMRC notices. National Insurance category letters follow each employee's circumstances. Full Payment Submissions are filed from the run, and Employer Payment Summaries cover statutory pay recovery and apprenticeship levy where it applies.
HMRC receives accurate data on every payday.
Overtime and shift premiums push earnings over and under the auto-enrolment thresholds from week to week. The system reassesses each worker every period, enrols the newly eligible, handles opt-outs and postponement, and sends contribution data to your pension provider in the format it accepts.
Pension compliance holds up when earnings swing.
Absence recorded in your attendance system triggers statutory sick pay checks against the current qualifying rules, including linked periods of sickness, while maternity, paternity, adoption, shared parental, bereavement and neonatal care pay are calculated from the correct reference period. On a shop floor where earnings depend on overtime, getting average weekly earnings right is what keeps these payments accurate. Recoverable amounts flow to the Employer Payment Summary.
Absence and family leave are paid correctly without manual workings.
Union check-off, salary sacrifice, payroll giving, canteen and tool schemes are set up as deductions with start and end dates and their own consent records. Totals by deduction type are exported for each recipient after the run.
Voluntary deductions are traceable to a signed consent.
Approved runs create BACS files per employing company, ready for your bank's upload or your bureau. Payment reports split by site help finance reconcile labour cost for each plant or depot.
Payments and cost reports agree with each other.
Workers on the floor and on site see itemised payslips with the hours they were paid for, their holiday balance and year end forms. Help text can explain each pay line in simpler words, and a query button routes questions to the right payroll officer.
Pay questions are answered without a trip to the office.
Who we build for
Choosing a payroll software development company for Birmingham work starts with an honest question about fit. Custom payroll software development in Birmingham is worth considering when your payroll team spends more time fixing exceptions than checking results. In this region the trigger is usually shift complexity, a mix of employees and subcontractors, or growth across several sites that each kept their own way of working. These four situations come up most often, and each starts with a different first release. If a packaged product would serve you better, we say so in discovery.
Plants in Tyseley, Aston or the wider Black Country may run different shift patterns, bonus schemes and union agreements. We turn those agreements into rules the system applies to clock data, so weekly pay for several hundred operatives does not depend on one person's spreadsheet. Reports by plant and cost code go straight to finance, and supervisors approve hours from a simple screen.
We need the current collective agreements to model rules correctly.
Construction firms pay directly employed operatives through PAYE while paying subcontractors under CIS. Both need to be correct, on time and reconciled to each project. We build a system that keeps the two separate in law but joined in reporting, with project codes, site approvals and the monthly CIS return prepared alongside weekly payroll. Travel and subsistence for operatives moving between sites can be paid through expenses or payroll according to the treatment your advisers confirm.
Exhibition and venue operators around the NEC and distribution firms near the motorway network take on large numbers of short-term staff for busy periods. Starters need adding quickly with the right starter declaration, and leavers need P45s without delay. We focus on fast onboarding, accurate first and last payslips, and weekly runs that cope with volume. Right to work evidence and contract details come across from your HR or onboarding tool, so payroll is not the place where missing paperwork is discovered on the Friday before payday.
Firms in the business district are often paid monthly but carry complexity elsewhere: salary sacrifice, payrolled benefits, partner drawings handled outside PAYE, and several entities. We build a monthly payroll with clean entity separation, links to your HR and practice management systems, and reports partners can read.
Partner profit shares stay outside payroll unless your advisers say otherwise.
Engagement options
Most Birmingham employers start with a fixed scope project for one company or one workforce group, often the weekly paid floor staff where the pain is greatest, and then bring the monthly payroll across. Employers with frequent changes to agreements or sites keep us on a retainer for updates and support. Groups with a long roadmap, such as adding HR and attendance modules later, can take a dedicated team. Scope, acceptance tests and responsibilities are always written down, and all meetings run by video call. Where your payroll team works shifts as well, we schedule reviews around the pay cycle so testing never collides with a live run.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
We pick a technology stack that handles high-volume calculations, keeps a full audit history and suits the people who will maintain it. Payroll data is hosted where you agree, set up to meet UK GDPR, with access split by site and role.

03Marketing and tracking
By modelling your agreements and pay groups before talking about screens.
We collect contracts, shift agreements and a sample of recent payslips, then list every pay element and the rule behind it. From that we decide what goes in the first release, usually the weekly operatives' payroll with clock data, and what follows. Cost and timing depend on the number of rules, sites, integrations and parallel runs, and we explain each driver before you commit.
