BambooHR tracks PTO, but it cannot tell you who is cleared for controlled work
For a Simi Valley aerospace or biotech employer, HR is not just PTO and payroll, it is tracking which employees are US persons eligible for ITAR-controlled work and whose certifications are current.

For a Simi Valley aerospace or biotech employer, HR (Human Resources) is not just PTO and payroll, it is tracking which employees are US persons eligible for ITAR-controlled work and whose certifications are current. When BambooHR or Gusto cannot hold that, custom HR software at $50k to $120k over 4 to 7 months does.
BambooHR, Workday, Gusto, and ADP handle the universal HR motions well: onboarding, PTO, benefits, payroll. They were not built for the question a Simi Valley defense subcontractor has to answer every day, which is whether a given employee is a US person eligible to handle ITAR-controlled technical data and parts. That eligibility status, and the documentation behind it, ends up in a spreadsheet next to the HR system that should own it.
The same gap hits biotech and pharma employers tracking training and certification currency. A standard HR tool does not enforce that an operator's required cert is current before they can be assigned to controlled or regulated work. So the floor relies on someone remembering, and the audit finds the gap.
What HR costs in Simi Valley
| Project scope | Typical cost | Timeline |
|---|---|---|
| Eligibility and certification tracking module | $50k to $70k | 4 to 5 months |
| Add ERP (Enterprise Resource Planning) integration and work-assignment gating | $70k to $100k | 5 to 6 months |
| Full HR compliance platform with audit reporting | $100k to $120k | 6 to 7 months |
The fix: HR built for Simi Valley, not rented
Custom HR software lets a Simi Valley employer make eligibility and certification first-class data that actually gates work. The system knows who is a US person eligible for ITAR work, which certs are current, and it can feed that to your ERP so the floor cannot assign controlled work to an ineligible or uncertified employee. Standard HR tools track people, this tracks who is cleared to do the work.
- You track ITAR eligibility in a spreadsheet beside your HR tool
- Nothing enforces that controlled work goes only to eligible employees
- Certification currency is not tied to who can do regulated work
- Audits keep surfacing scattered employee compliance documentation
- You have no controlled work and standard HR tools fully cover you
- Payroll and benefits are your only real HR needs
- BambooHR or Gusto with light spreadsheets is genuinely sufficient
- You cannot commit to maintaining compliance logic over time

How long it takes, phase by phase
Exactly what you get
You get an HR system that answers the question a Simi Valley defense employer asks daily: is this person a US person eligible for ITAR-controlled work, and are their certifications current. Eligibility and cert status are first-class data, and they feed your ERP so the floor physically cannot assign controlled work to an ineligible or uncertified employee. Expiry alerts fire before a cert lapses, and audit reporting is a query. It connects to your ERP, internal tools, and field service management software so eligibility follows the work.
How to choose a developer in Simi Valley
Pick a team that understands ITAR workforce rules and the difference between storing eligibility and enforcing it. Ask how they would gate a work assignment on eligibility and certification currency, and how they protect sensitive compliance data. Many shops keep a standard payroll tool and integrate, so confirm the team can do that cleanly. The right partner spends discovery on your compliance scope before quoting.
- ITAR US-person eligibility tracked and enforced as first-class HR data
- Certification and training currency tied directly to work assignment
- Audit-ready employee compliance records in one system, not scattered files
- Eligibility status fed to your ERP so the floor cannot misassign controlled work
- Automatic alerts before a required certification expires
- You give up the polished payroll and benefits ecosystem of BambooHR or ADP
- Often you still keep a standard tool for payroll and integrate, adding complexity
- You own keeping eligibility and compliance logic current as rules change
- For a shop with no controlled work, this is unnecessary over off-the-shelf HR
- !They treat eligibility as a custom field, ask how it gates work assignment
- !No experience with ITAR workforce rules, ask for a comparable compliance build
- !They ignore ERP integration, ask how eligibility reaches the floor
- !Weak on sensitive-data access, ask how they protect compliance records
- !They quote without your compliance scope, ask for a discovery phase first

Frequently asked questions
Can BambooHR or Workday track ITAR eligibility?
Only as a custom field with no enforcement. They cannot gate work assignment on eligibility, which is the part that matters for a Simi Valley defense shop. That gap is why employers commission custom HR compliance software.
Do we have to replace payroll too?
Usually not. Most shops keep a standard payroll and benefits tool and integrate it, building custom only for the eligibility and certification logic that off-the-shelf HR cannot enforce.
How does eligibility reach the shop floor?
The HR system exposes eligibility and certification status to your ERP, so when a job is assigned the system checks the operator is cleared and current before allowing it.
What about certification expiry?
The system tracks currency and alerts before a required cert lapses, so an operator is never quietly assigned regulated work on an expired certification.
Is this worth it without controlled work?
No. If you have no ITAR or regulated-certification requirements, standard HR tools cover you and custom is unnecessary spend.
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.
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.
What security does custom HR software need for employee data?
The baseline is encryption at rest and in transit, role-based access so salary and medical data are visible only to the right people, multi-factor authentication, and an audit log of who viewed what. If you have EU employees, GDPR applies; if you plan to sell the software to other companies later, SOC 2 Type II becomes a sales requirement. Ask any agency to walk through their access-control design before signing, because HR data is the most sensitive dataset most companies hold.
Can custom software replace ADP Workforce Now?
It can replace the HR layer, meaning records, onboarding, time off, and reporting, while keeping ADP's payroll engine underneath through its APIs, which is what most Digital Heroes clients on ADP choose. Rebuilding payroll tax calculation itself is rarely worth it, because ADP and Gusto maintain tax tables across thousands of jurisdictions. You get your workflows back without taking on tax liability.
Should we build our own payroll engine or integrate with a payroll provider?
Integrate, almost without exception; payroll tax across US federal, state, and local jurisdictions is a compliance business rather than a software feature, and getting it wrong creates real liability. Keep ADP, Gusto, or Paychex as the engine and build your workflows on top through their APIs. Nearly every payroll-connected platform Digital Heroes has delivered integrates instead of rebuilding, and the exceptions regretted it.
What should version one of a custom HR system include?
Employee records, onboarding checklists, time-off requests, and a payroll sync, which is roughly 12 to 16 weeks of work; save applicant tracking, performance reviews, and analytics for version two. The most expensive mistake in HR builds is scoping all ten modules into version one and launching nothing for a year. Ship the four workflows that hurt most, then let real usage set the roadmap.
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.
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.
Should I hire a freelancer or an agency to build our HR system?
A freelancer works for a single module or one integration, but a full HR platform needs design, backend, security review, and QA running at once, which is agency territory. Senior freelancers in Simi Valley usually quote $80 to $150 an hour, and everything stops when they take a vacation or a bigger contract. For software holding every employee's salary and personal data, a bus factor of one person is the real cost.
How long does it take to build a custom HR system?
A working first version takes 12 to 16 weeks in Digital Heroes projects: employee records and onboarding first, then time off and reporting. A full platform with applicant tracking, performance reviews, and payroll integration is a 6 to 9 month effort. Anyone quoting a complete HR suite in 4 weeks is describing a template, not custom software.
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.
Why do agencies charge for a discovery phase instead of quoting for free?
Because an accurate quote requires real work: mapping your workflows, finding the edge cases, and writing a specification, which typically takes 1 to 3 weeks and costs $2,000 to $10,000 at Digital Heroes depending on system complexity. You leave discovery owning a written spec and a fixed price you can take to any vendor, so the money is not locked into one agency. Free estimates are guesses, and the guess usually becomes your budget overrun six months later.
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.
How long does it take to build a custom web or mobile app from scratch?
Plan on 8 to 16 weeks for a focused first version and 4 to 9 months for a larger platform, which is the typical spread across Digital Heroes builds. The first 2 to 3 weeks go to discovery and design before any production code ships. The two things that stretch timelines most are integrations with legacy systems and slow feedback from your side, not developer speed.
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.
