We are a New York HRM software development company building custom HRMS platforms that are easier to use, easier to scale, and built around measurable business goals. Our HRM software process covers payroll, attendance and time tracking, onboarding, leave management, performance reviews, employee self service, recruitment, SSO, and systems of record integrations.
Tell us about your HR system.
Most companies should configure an off-the-shelf HRMS. Standard hire-to-retire flows are cheaper and safer as a subscription than as custom code.
A custom HRMS earns its cost in three scenarios. First, your people process is so unusual that a packaged suite cannot model it without painful workarounds. Second, you have a payroll or compliance rule no vendor supports in your jurisdiction. Third, you operate multiple legal entities where per-employee licensing crosses the cost of a custom build.
If two of those scenarios hold, build wins. Otherwise, configure a suite and integrate the gaps.
Shift-differential pay, union rules, multi-rate contractors, or project-based time allocation. Or a performance cycle that does not map to any packaged template. Configurable HRMS products flatten these into the nearest preset. A custom build keeps the rule exactly as your operation runs it.
A jurisdiction-specific payroll deduction. A labor regulation your suite has not implemented. Or a record-keeping requirement no generic system can satisfy. The FLSA recordkeeping rules alone trip up many off-the-shelf time-tracking presets.
Per-employee-per-month pricing across several legal entities, plus paid add-on modules, adds up fast at enterprise headcount. When three years of licensing crosses a one-time build plus a maintenance retainer, custom becomes the cheaper option and the better-fitting one.
An HRMS is not eight separate apps. It is one employee record viewed through eight lenses. We model the person, the position, and the compensation once.
Each module sits on that shared core so payroll, attendance, and leave never disagree. You can start with a single module and grow into the full platform.
6-12 weeks
Gross-to-net calculation, pay schedules, deductions, reimbursements, and payslip generation. Every run has a full audit trail.
Payroll is the highest-risk HR module. A wrong number is a legal and trust problem, so every calculation is versioned and replayable. For most US clients we integrate an existing engine like Gusto or a payroll API instead of re-implementing tax tables, and build the custom logic on top.
4-8 weeks
Clock-in and clock-out, shift schedules, overtime rules, geofenced or kiosk capture, and timesheet approval.
The hard part is the rule engine. Overtime thresholds, break rules, and rounding policies vary by region and contract. We make those rules data, not code, so HR can adjust policy without a release. Approved hours flow straight to payroll, no re-keying.
4-7 weeks
New-hire workflows: document collection, e-signature, equipment requests, account provisioning, and a structured first-30-days checklist.
A good onboarding module turns a chaotic email thread into a tracked sequence with owners and due dates. We wire it to the identity provider so a signed offer triggers account creation, and to payroll so a start date sets up the first pay run automatically.
3-6 weeks
Accrual policies, balance tracking, request and approval chains, holiday calendars, and carryover rules.
Leave looks simple until you hit pro-rated accrual for mid-year joiners, region-specific statutory minimums, and interactions with payroll. We model the accrual engine explicitly and show every employee their transparent balance, so HR stops fielding balance questions.
5-9 weeks
Goals, review cycles, 360-degree feedback, calibration, and one-on-one notes.
Every company runs performance differently. That is why packaged tools frustrate HR teams. We build the cycle your managers actually run: your rating scale, your competency framework, your cadence. Review data links to compensation so promotion and raise decisions sit on real records, not spreadsheet snapshots.
4-8 weeks
A single portal where employees update their details, view payslips, request leave, check time, and read company documents. Self-service is where an HRMS proves its value to everyone, not just HR.
We prioritize access control and audit. An employee sees their own record, a manager sees their team, HR sees everyone, and every view is logged. This portal pattern shares DNA with our SaaS development work.
6-12 weeks
Job postings, application capture, candidate pipelines, interview scheduling, and scorecards. A clean handoff into onboarding when a candidate accepts.
An ATS inside your HRMS means a hired candidate becomes an employee record without re-entering a single field. We keep pipeline stages configurable and candidate-facing pages fast. A slow apply form costs you applicants. This overlaps with workflow patterns in our CRM development service.
For most companies, the answer is to configure an established suite and integrate the gaps. For some, the answer is a custom HRMS.
The table below walks the decision we present on every scoping call. Our recommendation is grounded in your real constraints, not in what we would prefer to build.
| Decision factor | Configure BambooHR / Workday | Build custom HRMS |
|---|---|---|
| Process fit | Standard hire-to-retire flows | Unusual pay, shift, or review rules |
| Time to value | Weeks to configure | Months to build the first module |
| Cost shape | Per-employee-per-month, ongoing | One-time build plus maintenance retainer |
| Multi-entity | Licensing scales with headcount | Build cost is fixed regardless of headcount |
| Data control | Vendor-hosted, export on their terms | Your infrastructure, your export paths |
| Compliance edge cases | Limited to what the vendor supports | Built to your exact jurisdiction |
| Maintenance burden | Vendor handles updates | You own updates and uptime |
Even on a build, you rarely build everything. The integration layer keeps a custom HRMS from becoming an island. We connect the platform to systems of record you already pay for.
Payroll providers, identity tools, and benefits administrators stay authoritative. Your custom logic sits on top.
We integrate established payroll engines so we never re-implement tax tables you must keep current. Approved timesheets and compensation changes push out. Pay-run confirmations and payslips come back. The HRMS is the workflow brain. The payroll provider stays the calculation and filing authority.
Single sign-on through SAML or OpenID Connect. SCIM provisioning so a new hire gets accounts automatically and a leaver loses them on the last day. Identity is a security control, not a convenience. We treat deprovisioning with the same rigor as provisioning.
Accounting, benefits administration, and any existing HR data store. We use event-driven sync with retry logic and a dead-letter queue so a downstream outage never silently drops an employee change. Every sync is observable. We bring the same integration discipline to ERP development projects.
Scheduled exports. An analytics layer for headcount and turnover reporting. A documented schema so your finance and people-analytics teams can query the data directly. You own the export paths. No proprietary lock-in on your own people records.
Nobody should migrate an entire HRMS in one weekend. We sequence the build so each module proves itself in production before the next one starts. Risk stays low. HR adopts one workflow at a time.
The five phases below are the same checkpoints we bill against.
2 weeks
Requirements workshops with HR and payroll. Employee data-model mapping. A compliance and jurisdiction review. Architecture decision records.
Output is a scoped, fixed-price proposal with a recommended module sequence. If the honest recommendation is to configure a suite instead of building, we say so here.
2-3 weeks
The employee, position, and compensation records. Role-based access control. Audit logging. Identity integration. This is the foundation every module sits on.
We build and review it before any feature module starts. Get the data model wrong here and every module pays for it later.
4-8 weeks
We ship the highest-value, lowest-risk module first. Usually leave or self-service, not payroll.
It runs in production alongside your existing system so HR can compare outputs and build confidence. Real usage surfaces edge cases no workshop ever catches.
ongoing sprints
The remaining modules ship in priority order. Each integrates with the core and with modules already live.
Payroll typically goes last because it depends on attendance and leave being trusted first. Every module gets a parallel-run period before it becomes the system of record.
1-2 weeks
Runbooks. An on-call plan. Admin training. A documented exit clause.
You own the code, infrastructure, and employee data. If you take the platform in-house, we document exactly how. Most clients keep us on a light maintenance retainer for compliance updates and the next module. That is your choice, not a contractual trap.
An HRMS holds the most sensitive data a company keeps: salaries, social security numbers, performance notes, health-related leave. The stack is chosen for safety and maintainability first.
Mature, well-understood tools mean a smaller attack surface, cheaper hiring, and an auditor who recognizes everything in the architecture diagram.
| layer | default |
|---|---|
| Backend language | TypeScript / Python |
| Web framework | Next.js / FastAPI |
| Database | Postgres + row-level security |
| Cache + jobs | Redis |
| Auth + SSO | SAML / OIDC / SCIM |
| Payroll | Provider API integration |
| Encryption | At rest + in transit |
| Audit logging | Append-only event log |
| Deploy | AWS / Vercel / client cloud |
| Observability | Sentry + structured logs |
Postgres with row-level security handles HR access control cleanly: an employee row is visible to that employee, their manager chain, and HR, enforced at the database, not just the application. We follow the OWASP ASVS as the security baseline and lean on platform primitives like the Content Security Policy for the self-service front end.
Hosting choice follows your compliance posture. AWS when you need a signed BAA or a specific data-residency region; managed platforms when you do not. We measure the self-service portal against Core Web Vitals because an HRMS people dread opening is an HRMS people work around. The build standards mirror our custom software development and broader software development practice.
The questions teams ask most before booking a scoping call: when custom HR software beats a suite, what a build costs in time, how payroll is handled, how data security works, whether we integrate existing tools, and how we price.
Three conditions usually justify a build. First, your people process is so unusual that a packaged suite cannot model it without workarounds, like non-standard pay rules or a custom review cycle. Second, a payroll or compliance requirement no vendor supports in your jurisdiction. Third, you operate multiple entities where three years of per-employee licensing crosses the cost of a custom build.
If fewer than two of these hold, configure a suite and integrate the gaps. If two or more hold, a custom HRMS is the better call.
A single module ships in 3 to 12 weeks depending on which one; leave is the fastest, payroll and the ATS are the slowest. A full multi-module HRMS runs 16 to 28 weeks across discovery, core data model, and a sequenced module rollout. We never migrate everything at once. The first module goes live in parallel with your existing system so HR can compare outputs before anything depends on the new platform, then the rest follow in priority order.
Rarely, and only when the requirement forces it. Tax tables change constantly and getting them wrong is a legal problem, so for most clients we integrate an established payroll engine or API and build the custom logic around it: pay schedules, deductions, reimbursements, and the audit trail. We re-implement calculation only when a jurisdiction or pay rule genuinely is not supported by any provider, and even then we version every run so it is replayable and auditable.
HR data is the most sensitive data most companies hold. Security is in scope from day one. We default to encryption at rest and in transit, least-privilege database access with row-level security, append-only audit logs, and no hardcoded credentials. The OWASP ASVS is our baseline.
For regulated clients we add SOC 2 gap analysis, a HIPAA BAA where health data appears, GDPR records of processing, and data-residency controls. Deprovisioning gets the same rigor as provisioning so a leaver loses access on their last day.
Yes, and on most engagements that is the point. We integrate payroll providers, identity tools through SAML, OIDC, and SCIM, benefits administrators, and your accounting system. The pattern is an event-driven sync with retry logic and a dead-letter queue so a downstream outage never silently drops an employee change. Existing systems of record stay authoritative for what they own; the custom HRMS adds the workflow and reporting your suite cannot, without forcing a rip-and-replace of tools that already work.
Every engagement is scoped. The 2-week discovery sprint is a fixed price. Module builds and full platforms are scoped against a written requirements document, with a fixed bid and an explicit change-request process. Maintenance retainers run monthly for compliance updates and the next phase.
We do not publish tiered packages because a single leave module and a full multi-entity HRMS sit at vastly different scopes. A range would mislead more than help. Book the scoping call. Your written scope and fixed quote land within 48 hours.
30-minute call to understand your people processes, your compliance constraints, and which modules to build first. Written scope and fixed-price quote within two business days. No proposal decks, no sales theater.
