Custom HR (Human Resources) software for a Glasgow events, engineering, or field-service firm runs £35,000 to £100,000 over 4 to 7 months. BambooHR, Workday, Gusto, and ADP are built for salaried, desk-based staff with predictable hours. Your workforce is shift-based: event crews who surge for a festival or a Hydro show, field engineers on rotating sites, contractors who flex by the week. Custom HR software models that real workforce, shift scheduling, certifications, availability, and variable pay, so HR isn't reconstructing who worked what from a stack of timesheets.
You bought BambooHR or Gusto for the HR basics and it handles holidays and records fine. Then your operation hit its real shape: crews scheduled by show, engineers rostered across sites, pay that changes with shift type, overtime, and unsociable hours. The off-the-shelf tool has no concept of a shift pattern, a venue, or a certification that expires, so scheduling lives in a spreadsheet and payroll is a manual reconciliation every cycle.
Workday and ADP are powerful but assume an enterprise of salaried roles. For a Glasgow events or field firm, the gaps that matter, who's available, who's certified to rig, whose ticket expires this month, simply aren't there. When the HR system can't hold the shift workforce, your managers run scheduling and compliance off spreadsheets and WhatsApp, and a missed certification or a payroll error is always one cycle away.
Budgeting a HR build in Glasgow
| Project scope | Typical cost | Timeline |
|---|---|---|
| Shift scheduling and certification HR core | £35k to £60k | 4 to 5 months |
| Full HR platform with variable-pay payroll | £70k to £100k | 5 to 7 months |
| Scheduling and certification layer over existing HR tool | £28k to £50k | 3 to 4 months |
The case for owning your HR
You build custom when your workforce is shift-based and the off-the-shelf HR tools simply don't model shifts, certifications, or variable pay. A Glasgow build encodes shift scheduling, certification expiry, availability, and your real pay rules in one system, so rostering, compliance, and payroll stop being separate spreadsheets. For an events or field firm, that means no uncertified crew on a job and no payroll reconstruction every cycle. It connects naturally to your field service management, project management, and accounting systems.
- Your workforce is shift-based and BambooHR has no concept of shifts or venues
- Certifications expire and you're tracking them in a spreadsheet, risking a non-compliant crew
- Variable pay is reconciled by hand every payroll cycle
- Rostering and availability run on WhatsApp, invisible to HR and payroll
- Your team is mostly salaried with predictable hours that BambooHR or Gusto fits
- You need standard HR records, holidays, and payroll more than shift logic
- Statutory payroll updates handled by a vendor matter more than custom pay rules
- You lack the budget to own HR software and its compliance maintenance
What your build should include
Glasgow HR: the full scope
Everything an HR build here can cover: time and attendance, applicant tracking system (ATS), BambooHR alternative, Workday integration, leave management, performance management software and custom HR software.
Delivery, week by week
Exactly what you get
HR software that fits a shift-based workforce: roster scheduling by venue, site, or show; certification and ticket tracking with expiry alerts; a variable-pay engine for overtime and unsociable hours; and crew self-service on mobile. Scheduling, compliance, and pay finally live in one system instead of three spreadsheets and a WhatsApp group. It integrates with your payroll and accounting software, your field service management, and your project management tools so the roster drives the rest of the operation.
How to choose a developer in Glasgow
Pick a developer who asks how your crews are actually scheduled before talking features. The good ones model your shifts, certifications, and pay rules; the weak ones show a generic holiday tracker. Glasgow's plain-spoken culture rewards honesty, so trust the firm that says stay on BambooHR if your team is really just salaried. Ask for a shift-workforce reference, confirm they understand UK payroll and pension rules, and make sure certification expiry and variable pay are in the first release.
- Shift scheduling for crews and engineers built in, ending the spreadsheet roster
- Certification and ticket expiry tracked, so no uncertified person ends up on a regulated job
- Variable pay, overtime, and unsociable-hours rules calculated automatically into payroll
- Live availability and rostering across venues and sites, visible to HR and managers
- One system linking scheduling, compliance, and pay instead of three disconnected ones
- You lose automatic UK payroll, PAYE, and pension auto-enrolment updates that Gusto and ADP ship
- Building HR software means owning sensitive employee data, security, and access controls yourself
- Statutory HR changes become your maintenance line rather than the vendor's
- For purely salaried teams, off-the-shelf is cheaper and a custom build is overkill
- !They demo standard HR records and skip shift scheduling; ask them to roster a multi-venue weekend on screen
- !No certification-expiry handling; ask how you'd be warned before a ticket lapses on a regulated job
- !Vague on variable pay; ask exactly how overtime and unsociable hours flow into payroll
- !No payroll integration plan; ask how calculated pay reaches your accounting system
- !No reference for shift-based workforces; ask for events, field service, or hospitality, not just office HR

Frequently asked questions
Why won't BambooHR or Gusto work for our crews?
They're built for salaried, desk-based staff and have no real concept of shifts, venues, certifications, or variable pay. For a shift-based events or field workforce, the parts that matter most simply aren't there, so scheduling and pay end up in spreadsheets anyway.
Can we keep our payroll provider and just build scheduling?
Yes. A scheduling and certification layer over your existing HR tool runs £28k to £50k in 3 to 4 months, adding shift logic and compliance tracking while keeping the payroll and records you already use.
How does certification tracking prevent compliance problems?
The system holds each person's tickets and certifications with expiry dates and alerts managers before they lapse, so you never roster an uncertified crew member onto a regulated job, which a spreadsheet routinely fails to catch.
Will it calculate our variable pay correctly?
A custom build encodes your real rules, overtime, shift premiums, unsociable hours, and feeds the result into payroll, replacing the manual reconciliation that causes errors every cycle.
What's the honest trade-off?
You take on sensitive employee data, security, and statutory updates that a vendor would otherwise handle. For a shift-based workforce the fit is worth it; for a salaried team it's overkill, and a good developer will tell you which you are.
Is Workday realistic for a company under 500 employees?
Usually not; companies that bring Digital Heroes their Workday quotes have been looking at six-figure implementations with 6 to 12 month rollouts before any customization starts. A custom HR platform scoped to what a 200-person company actually uses typically costs less than that implementation alone. Under 500 employees you would be paying for enterprise depth you will not touch for years.
What should I prepare before contacting an agency about HR software?
Bring four things: your current tool list with annual costs, headcount now and projected in two years, the five workflows that waste the most HR hours each week, and any compliance requirements like multi-state employment or union rules. A sample data export from your current system helps too. Digital Heroes scoping calls with this prepared produce a fixed quote in days instead of weeks.
What tech stack should custom HR software use?
Choose boring and hireable: React or Next.js on the front end, Node.js or Django behind it, and PostgreSQL for data, since Postgres row-level security maps cleanly onto salary visibility rules. That is the Digital Heroes default for HR systems because any future team can maintain it. Be wary of agencies pushing an exotic stack; you will be hiring for it for a decade.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
Can we keep using BambooHR while the custom system is being built?
Yes, and you should; the standard approach is to run both in parallel and cut over one module at a time, using BambooHR's API to keep employee data in sync. Your HR team keeps working normally while each new module is tested against real records. The final cutover then retires a system you have already replaced in daily use, not one you are gambling on.
Does my development team need to be located in Glasgow?
No, most software projects run fully remote without any quality penalty, and what actually matters is 3 to 4 hours of working-hour overlap and a fixed weekly demo call. A team based in Glasgow earns its premium in specific cases: hardware installations, warehouse or clinic floor shadowing, and discovery workshops where watching your staff work beats any written brief. Choose for senior engineers and a track record first, and treat geography as a tiebreaker.
What does it cost to maintain custom HR software after launch?
Plan for 15 to 20 percent of the original build cost per year, the average across Digital Heroes maintenance contracts, covering security patches, dependency updates, small feature changes, and monitoring. Hosting for a company under 1,000 employees usually adds $100 to $400 a month on AWS or similar. Unlike BambooHR or Workday, the cost does not grow every time you hire ten more people.
Do we need a local development team, or can HR software be built remotely?
Remote works for almost all of it. The exceptions are hardware projects like biometric time clocks or badge readers, which need someone physically in Glasgow for installation and testing. Discovery workshops go faster in person, so some clients book one on-site week at the start and run everything else remote. Judge teams on their HR delivery record, not their zip code.
What happens to our HR system if the development agency shuts down?
Nothing, if the handover was done right: you hold the repository, the cloud accounts, the deployment runbook, and the schema documentation, so any competent team can take over maintenance. This is why code ownership and infrastructure access belong in the contract rather than in goodwill. Ask for the handover package as a deliverable of the first release, not something promised for later.
How many SaaS seats do we need before building custom becomes cheaper?
The crossover usually shows up between 20 and 50 seats on premium tiers. Salesforce Enterprise lists at $165 per user per month, so 40 users cost about $79,000 a year in subscriptions, which is real money against a custom system you would own outright. Run the comparison over three years: if subscription spend beats the build cost plus 15-20% annual maintenance, custom wins on price before you even count workflow fit.
Should I hire a freelancer or an agency for my software project?
A skilled freelancer is the right call for a single-discipline scope under roughly $15,000, like a website, a plugin, or one integration. Above that, projects need design, backend, testing, and project management at once, and a solo builder becomes the single point of failure: if they get sick or take a bigger client, your project simply stops. Agencies bill 20-40% more per hour but carry continuity, code review, and someone to escalate to, which is what you are actually buying.
Who can build custom HR software for a business in Glasgow?
Digital Heroes builds custom HR software systems for operators who have outgrown the off-the-shelf tools in their category. The work is delivered remotely: our engineers work from Delhi and Lucknow, leadership is in New York, and some team members live in London and Sydney and work remotely from there. We have no office in Glasgow. You can chat with the team directly, and every form gets an email reply within 24 hours.
