BambooHR knows the holiday balance but not the clearance, so cleared staffing runs on a spreadsheet
Custom HR software for a Portsmouth defence or marine employer runs £40,000 to £100,000 over 3 to 6 months.
On this page
Custom HR (Human Resources) software for a Portsmouth defence or marine employer runs £40,000 to £100,000 over 3 to 6 months. BambooHR, Workday, and Gusto handle leave, payroll, and reviews well, but none of them track the thing that governs your workforce planning: who holds which security clearance, sponsored by whom, valid for which classified contract.
Your HR system manages holidays and payroll fine, but the question that actually shapes your staffing, can this person legally work this classified contract, lives in a separate spreadsheet because BambooHR has no clearance fields. So when a new naval subcontract lands, someone manually cross-references staff against clearances, sponsorships, and expiry dates, and that's why onboarding cleared people to a contract takes weeks.
Workday can be configured for almost anything, but you'll pay enterprise money and consultants to bolt clearance tracking onto a platform that has no native concept of it. Gusto and ADP don't pretend to. For a security-aware employer with strong Royal Navy ties, the clearance dimension isn't an add-on; it's the core of workforce planning.
Where the off-the-shelf tools fall short
- Security clearance level, sponsor, and validity have no native field in BambooHR or Gusto
- Cleared-staff-to-contract eligibility is cross-referenced manually, dragging onboarding out for weeks
- Clearance expiries and renewals aren't tracked, risking someone working a contract they're no longer cleared for
- Configuring Workday to track all this costs enterprise money for what should be a core capability
Custom HR: what Portsmouth teams actually get
Custom HR software makes clearance a first-class part of the employee record: level, sponsor, validity, and which classified contracts it permits, with expiry alerts and eligibility checks built in. Staffing a new naval subcontract becomes a query, not a week of spreadsheet cross-referencing, and you never risk putting someone on a contract their clearance no longer covers.
- Clearance and contract eligibility govern your staffing and live in spreadsheets today
- Cleared-staff onboarding to contracts is a recurring, visible bottleneck
- You need clearance expiry tracking your current HR tool can't provide
- Your workforce is commercial with no clearance dimension
- You need standard HR (leave, payroll, reviews) and nothing security-specific
- A small team fits BambooHR or Gusto without workarounds
- Clearance level, sponsor, and validity live in the employee record, ending the side spreadsheet
- Contract-eligibility checks turn cleared staffing into a query instead of weeks of cross-referencing
- Expiry and renewal alerts stop anyone working a contract their clearance no longer covers
- Workforce planning for classified contracts becomes fast and reliable
- Standard HR (leave, payroll, reviews) still works, integrated with the clearance core
- Clearance and sponsorship data is sensitive, so you take on real handling and access obligations
- Building HR software means recreating standard functions that off-the-shelf tools give free
- Integration with payroll providers adds cost and complexity
- If clearance isn't central to your workforce, the custom case is much weaker

Timeline: what happens, and when
Exactly what you get
HR software where clearance is core: each employee record carries clearance level, sponsor, validity, and permitted classified contracts, with eligibility checks and expiry alerts built in. Staffing a naval subcontract becomes a query, not weeks of cross-referencing, and standard HR (leave, reviews, payroll integration) runs alongside. Sensitive clearance data is governed by role-based access, and the system connects to your existing payroll provider.
How to choose a developer in Portsmouth
Choose a team that understands both HR software and sensitive-data handling. Ask how they'd model clearance eligibility and expiry, how they'd govern access to that data, and how they'd integrate payroll. A partner experienced with regulated workforces will get it immediately. One that proposes configuring Workday to fake clearance tracking is steering you toward enterprise cost for a capability a focused build delivers cleaner.
- !They suggest configuring Workday for clearance. Ask what that really costs versus a focused build
- !They treat clearance as a custom text field. Ask how eligibility checks and expiry alerts work
- !No sensitive-data handling plan. Ask how clearance records are governed and access-controlled
- !No payroll integration experience. Ask how they'll connect to your provider
- !They ignore expiry tracking. Ask how you'd be warned before a clearance lapses

Frequently asked questions
Can't BambooHR just store clearance as a custom field?
It can store the text, but it can't run eligibility checks, alert on expiries, or stop someone being staffed to a contract their clearance doesn't cover. Custom software makes clearance an enforced part of workforce planning, not a passive note.
Is it safe to hold clearance data in HR software?
Clearance level is sensitive personal and commercial data, so it needs governed, role-based access and proper handling. A capable build restricts visibility and keeps an audit trail of who saw and changed what.
Does it replace our payroll?
Not necessarily. Most builds integrate with your existing payroll provider rather than rebuilding payroll, which keeps cost down and lets the custom system focus on the clearance and eligibility logic that's actually missing.
How does it speed up staffing a contract?
Eligibility checking turns the question 'who can legally work this classified contract' into an instant query against clearance level, sponsor, and validity, instead of a manual cross-reference that takes weeks.
What about standard HR like leave and reviews?
Those run alongside the clearance core. You get normal HR functions integrated with clearance tracking, so staff aren't bouncing between a spreadsheet and a separate HR tool.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?
Yes, and connecting your existing tools is one of the main reasons to build custom: mainstream platforms like QuickBooks, Stripe, Shopify, and Google Workspace all publish documented APIs. Budget 1 to 3 weeks of work per integration depending on API quality and how much data flows in both directions. Ask any vendor whether they have integrated with your specific tools before, because quirks like QuickBooks' OAuth token handling and API rate limits get learned on someone's project, and it should not be yours.
Is custom software more secure than off-the-shelf SaaS?
Neither is secure by default; security tracks the practices of whoever builds and operates the system, not the model. SaaS gives you the vendor's certifications and patching but puts your data in a shared multi-tenant platform on their terms, while custom gives you full control over data residency, access rules, and compliance requirements like HIPAA, with the responsibility sitting with you and your agency. Before hiring anyone for a system holding sensitive data, ask for their security checklist: encryption at rest and in transit, an OWASP Top 10 review, role-based access, and a penetration test before launch.
Will custom HR software scale from 100 to 1,000 employees?
Yes, comfortably. A thousand employee records is a tiny dataset by database standards, so the real scaling work is organizational: multi-state tax setups, layered approval chains, and role hierarchies. A properly designed system absorbs those through configuration instead of code changes. This is where custom beats off-the-shelf, because you add complexity as you actually acquire it rather than paying for an enterprise tier up front.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
What would it cost to build just one HR module, like leave management or onboarding?
A single well-scoped module such as leave management, onboarding checklists, or a review cycle tool usually costs $8,000 to $25,000 and ships in 4 to 8 weeks in Digital Heroes projects. This is the cheapest way to fix the one workflow BambooHR or Gusto handles badly without replacing the whole system. The module reads and writes through your existing platform's API, so nothing gets migrated.
What are the biggest mistakes first-time software buyers make?
Choosing the lowest bid, paying more than 30-40% upfront instead of on milestones, skipping a written specification, and having no maintenance plan for after launch. The most expensive of the four in Digital Heroes rescue projects is the missing spec: without written acceptance criteria, done becomes an argument instead of a checklist, and every disagreement resolves in the vendor's favor. Fix those four and you have avoided most of the ways these projects fail.
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.
How long until custom HR software pays for itself?
For companies over 100 employees, payback typically lands in 24 to 36 months across Digital Heroes projects, driven by cancelled per-seat subscriptions and recovered HR admin hours. A 200-person company spending $40,000 a year on HR tools plus a day a week of manual workarounds crosses even faster. Under 50 employees the math usually favors staying on Gusto or BambooHR, and an honest agency will tell you that.
How many developers does it take to build an HR platform?
A typical Digital Heroes HR build runs 4 to 6 people: a project lead, a designer, two or three developers, and a QA engineer, with security review pulled in at milestones. A single module needs just two. Bigger teams rarely ship HR systems faster, because the bottleneck is decisions about workflows, not typing speed.
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 Portsmouth 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.
Who can build custom HR software for a business in Portsmouth?
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 Portsmouth. You can chat with the team directly, and every form gets an email reply within 24 hours.
