BambooHR was built for salaried desks, and your Glasgow event crews don't sit at one
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
If hr is on the roadmap, pos, warehouse management, helpdesk & ticketing usually follow within the year. Budget them as one conversation.

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.
