Payroll Management for Growing Companies: Beyond Basic Processing
Payroll is the largest expense for most service businesses. Getting it right means accurate paychecks, happy employees, and compliance with complex tax regulations. Getting it wrong means penalties, disgruntled staff, and audit nightmares. This guide covers payroll management from provider selection to multi-state compliance.
When you had 5 employees in one state, payroll was simple. Enter hours, run payroll, done. At 25 employees across 5 states with varying compensation structures, it's a different beast entirely.
Growing companies need payroll systems that scale with them—handling new states, benefit complexity, compliance changes, and integration with other systems. This guide helps you navigate payroll as you grow.
Payroll Complexity as Companies Grow
Simple Stage (1-10 Employees)
- Single state
- Mostly salaried or simple hourly
- Basic benefits (if any)
- Owner can handle or simple provider
Growing Stage (10-50 Employees)
- Multiple states (remote work)
- Mix of salary, hourly, commission
- Benefits administration complexity
- Need robust provider with good support
Scaling Stage (50-200 Employees)
- Many states, possibly international
- Complex compensation (equity, bonuses)
- Full benefits suite
- HRIS integration requirements
- Need enterprise-capable provider
The Complexity Creep
Payroll complexity doesn't grow linearly with headcount—it often accelerates. One remote employee in a new state adds registration requirements, new tax calculations, and filing obligations. Plan for complexity before it overwhelms you.
In-House vs. Outsourced Payroll
In-House Payroll
- Pros: Full control, no vendor dependency, may be cheaper at very large scale
- Cons: Requires expertise, compliance risk on you, software costs, time-consuming
- Best for: Large companies with dedicated payroll staff (200+ employees typically)
Outsourced Payroll
- Pros: Compliance handled, expertise included, scales easily, time savings
- Cons: Monthly cost, dependent on vendor, less control
- Best for: Most growing companies (10-200 employees)
Our Recommendation
For companies with 10-200 employees, outsourced payroll is almost always the right choice. The compliance complexity, time savings, and cost of errors make self-processing risky. Focus your team on running the business, not payroll tax filings.
Payroll Provider Landscape
Modern Cloud Providers
- Gusto: Great UX, strong for smaller companies, solid benefits
- Rippling: HR platform with payroll, good for tech companies, scales well
- Justworks: PEO model, bundled HR/benefits/payroll
Traditional Providers
- ADP: Market leader, full suite, better for larger companies
- Paychex: Similar to ADP, strong service network
- Paylocity: Mid-market focus, good HR integration
International Specialists
- Deel: International contractors and EOR services
- Remote: Similar to Deel, strong in EOR
- Oyster: Global employment platform
Multi-State Payroll Compliance
Remote work has made multi-state payroll the norm, not the exception. Each state brings new compliance requirements.
What Multi-State Requires
- State registration: Register as employer in each state
- Tax withholding: Withhold correct state (and sometimes local) taxes
- Unemployment insurance: State UI registration and tax payments
- Workers' compensation: Coverage in each state
- Tax filings: Quarterly and annual returns per state
Complexity Drivers
- Varying rules: Each state has different withholding rates and rules
- Local taxes: Some localities have additional taxes (NYC, Philadelphia)
- Reciprocity: Some states have reciprocal agreements
- Nexus triggers: One employee in a state can create tax nexus
Let Your Provider Handle It
Multi-state compliance is exactly why you should use a good payroll provider. They handle state registrations, calculate withholdings, and file returns. Trying to manage this in-house across many states is error-prone and time-consuming.
Benefits Administration
Payroll and benefits are intertwined—benefits affect gross-to-net calculations, and payroll systems often manage benefits enrollment.
Common Benefits
- Health insurance: Medical, dental, vision
- Retirement: 401(k) with company match
- Life/disability: Basic and supplemental coverage
- FSA/HSA: Tax-advantaged healthcare accounts
- PTO/leave: Vacation, sick, parental leave
Integration Considerations
- Bundled vs. separate: Some payroll providers include benefits; others integrate
- Deduction accuracy: Benefits deductions must flow correctly to payroll
- Enrollment sync: Changes in benefits should update payroll automatically
Payroll Accounting and Integration
Payroll Journal Entries
Each payroll run creates journal entries:
- Gross wages: Debit wage expense accounts
- Employer taxes: Debit employer tax expense
- Employee withholdings: Credit liability accounts
- Net pay: Credit cash (or payroll clearing)
Integration with Accounting
- Automatic sync: Best providers push journal entries to accounting software
- Mapping: Map payroll accounts to GL accounts
- Timing: Entries should post when payroll is processed
Reconciliation
- Liability reconciliation: Verify payroll liabilities match what's owed
- Tax deposit verification: Confirm taxes were deposited correctly
- Bank reconciliation: Match payroll cash to bank statement
Payroll Fraud Prevention
Payroll is a common target for fraud. Controls protect against both internal and external threats.
Common Fraud Types
- Ghost employees: Payments to fictitious employees
- Falsified hours: Inflated time worked
- Unauthorized raises: Salary changes without approval
- Commission manipulation: Inflated sales for commission
Prevention Controls
- Segregation of duties: Different people add employees, process payroll, review
- Payroll review: Someone reviews every payroll before processing
- New employee verification: Verify identity and authorization
- Change approval: Pay changes require documented approval
- Bank account verification: Verify direct deposit changes
Frequently Asked Questions
Should we handle payroll in-house or outsource it?
Most growing companies should outsource payroll to a specialized provider. The compliance complexity (tax filings, multi-state rules, changing regulations) makes in-house payroll risky unless you have dedicated payroll expertise. Modern payroll providers like Gusto, Rippling, and Paychex handle compliance, integrate with your systems, and cost less than a dedicated payroll person.
What payroll provider is best for growing companies?
It depends on your needs. Gusto is excellent for simplicity and user experience (good up to ~100 employees). Rippling offers more HR integration and scales better. ADP and Paychex have the most features but can be more complex. For international, consider Deel or Remote. Choose based on your specific needs: employee count, states, benefits complexity, and integration requirements.
How do we handle payroll for employees in multiple states?
Multi-state payroll requires registering as an employer in each state, withholding state and local taxes correctly, and filing state payroll tax returns. Good payroll providers handle this automatically—they register you, calculate withholdings, and file returns. The complexity is why outsourcing payroll becomes even more valuable as you add states.
What is the difference between an employee and a contractor?
The IRS uses multiple factors to determine classification, focusing on behavioral control (do you direct how work is done?), financial control (do they have business expenses, work for others?), and relationship type (is there a contract, benefits?). Misclassification is a significant risk—penalties include back taxes, benefits, and fines. When in doubt, consult with an employment attorney.
How do we pay international employees or contractors?
For international employees, you typically need either a local legal entity or an Employer of Record (EOR) service like Deel, Remote, or Oyster. EORs employ your workers legally in their country and handle local compliance. For contractors, you can pay directly via international transfer or through contractor payment platforms. Always verify that contractors are truly contractors under local law.
