The cost of payroll for a small business in Manchester is rarely just the price shown on a software page or bureau quote. The full cost also includes the time spent collecting hours, checking changes, resolving exceptions, answering employee questions and correcting mistakes.
That distinction matters for employers with shift-based or variable-hour teams. A restaurant, care provider, retailer or events business might have an affordable payroll subscription but still lose a working day every month to spreadsheets and manual checks.
This guide explains the costs to include, gives you a worked example and helps you compare three common approaches: running payroll yourself, using an accountant or bureau, and using connected payroll software.
What should you include in payroll cost?
Start with every cost required to move from approved employee information to accurate pay, payslips, reports and payments. Split the calculation into visible and hidden costs.
Visible payroll costs
The visible costs are the amounts that normally appear on an invoice:
- payroll software subscription;
- accountant or payroll bureau fee;
- setup, implementation or migration support;
- charges per employee or per payslip;
- employee portal or mobile access charges;
- pension integration fees;
- support and training;
- charges for additional payrolls, companies or pay frequencies.
Ask suppliers whether the quoted price includes year-end work, starters and leavers, corrected pay runs, pension files and support. Two quotes can look similar while covering different work.
Hidden payroll costs
The hidden cost is the internal time surrounding the pay run:
- collecting timesheets, overtime and absence information;
- chasing managers for approvals;
- checking starters, leavers and pay-rate changes;
- reviewing holiday, sickness and statutory payment information;
- reconciling rotas or time records with payroll inputs;
- correcting missed hours or duplicated entries;
- answering payslip questions;
- preparing pension and finance reports;
- checking the final payroll before submission.
Convert that time into money using the fully loaded hourly cost of each person involved. If an owner spends four hours and a manager spends three hours on payroll, both belong in the calculation even when neither records the time as a separate expense.
A worked monthly payroll-cost example
Consider a fictional Manchester hospitality business with 24 employees paid monthly. The business runs payroll in-house and collects variable hours from two site managers.
| Cost item | Monthly assumption | Estimated cost |
|---|---|---|
| Payroll software | Monthly plan | £75 |
| Payroll administrator | 6 hours at £24 per hour | £144 |
| Manager approvals | 4 hours at £22 per hour | £88 |
| Corrections and employee queries | 2 hours at £24 per hour | £48 |
| Pension and finance checks | 1.5 hours at £24 per hour | £36 |
| Average setup cost spread over 12 months | £600 divided by 12 | £50 |
| Estimated total | £441 per month |
The subscription is only 17% of this example's estimated monthly cost. The larger cost is the work required to prepare, check and correct the payroll.
This is not a market-price benchmark or a quote. Replace every assumption with your own supplier fees, staff costs and time records. A five-person office with fixed salaries may need much less preparation. A 40-person care or hospitality team with variable shifts may need considerably more.
Use this seven-step payroll cost calculation
- Add all monthly software, accountant or bureau fees.
- Add the cost of collecting and checking payroll inputs.
- Add the cost of manager approvals.
- Add time spent on pension, finance and statutory-payment checks.
- Add the average cost of corrections and employee queries.
- Spread one-off setup or migration costs across 12 months.
- Record avoidable costs separately, such as repeated corrections, duplicated systems or late-payment interest.
Run the calculation for at least three pay periods. One unusually simple or difficult month can distort the result.
Compare in-house payroll, a bureau and connected software
Running payroll in-house
In-house payroll gives the employer direct control over timing and checks. It can work well when employee data is stable and someone has the knowledge and protected time to manage the process.
The risk is concentrating knowledge in one person. Include cover for holidays or sickness, training time and the cost of keeping up with payroll responsibilities. Low software fees do not compensate for an unreliable approval process.
Using an accountant or payroll bureau
A bureau can remove calculation and submission work, but the employer still needs to provide complete, approved information. Ask exactly what the fee includes and what happens when information arrives late or a correction is needed.
A bureau does not automatically remove the internal cost of chasing timesheets, confirming changes or answering employee queries. Measure the work on both sides of the handover.
Using connected payroll software
Connected software can reduce rekeying when HR records, approved time, absence and payroll preparation share a controlled workflow. The value depends on the process around the system: clear cut-off dates, named approvers and a visible exception review are still essential.
Read the Workmax payroll hub for more payroll guidance. Care employers with variable shifts can also use the complete guide to care payroll to map the records that feed each pay run.
Do not treat compliance deadlines as optional admin
HMRC says employers should send a Full Payment Submission on or before employees' payday. The FPS reports payments and deductions, and errors should be corrected as soon as possible.
HMRC also says a monthly PAYE bill is generally due by the 22nd of the next tax month. A cheque sent through the post must reach HMRC by the 19th. Late payments may lead to interest and penalties.
These deadlines do not tell you which payroll product to buy, but they show why preparation time and reliable approvals belong in the cost model. A process that regularly reaches payroll day with missing information carries more risk than one with an earlier cut-off and documented review.
Questions to ask before choosing a payroll option
Use this checklist when comparing providers or reviewing your existing process:
- Is pricing fixed, per employee or per payslip?
- Are starters, leavers and corrected runs included?
- Who checks payroll inputs before processing?
- Can managers approve hours without emailing spreadsheets?
- How are pay-rate and bank-detail changes controlled?
- What support is available near payday?
- Can the system show which records are missing or unapproved?
- How are pensions and finance reports handled?
- What happens if the usual payroll owner is absent?
- How long will migration and parallel checking take?
The cheapest option is the one that produces an accurate, reviewable pay run at the lowest total cost, not necessarily the one with the lowest subscription.
How Workmax fits the calculation
Workmax is designed to connect HR records, scheduling, time tracking and payroll preparation so approved workforce information can move through a clearer process. That can reduce spreadsheet reconstruction and make exceptions easier to review before payroll is finalised.
The exact saving depends on your team, existing systems and approval process. Compare the features with your current workflow, review Workmax payroll, and check Workmax pricing before making a decision.
