Part-Time vs Full-Time Bookkeeper: When to Upgrade
How to Know When It’s Time to Go Full-Time
Most small businesses start with a part-time bookkeeper-a few hours a week, hourly pay, quick fixes.
But as transactions, payroll, and reconciliations multiply, one question always surfaces:
“Should I hire a full-time bookkeeper now?”
This guide explains when part-time stops working, what full-time actually adds, and how to decide between hiring or outsourcing.
The Short Answer
| Factor | Part-Time | Full-Time |
|---|---|---|
| Hours | 5-20 per week | 30-40 per week |
| Monthly Cost | $600–$1,500 | $4,000–$6,000 + taxes |
| Close Consistency | Moderate | High |
| Scalability | Limited | Good (until turnover) |
| Risk | Missed reconciliations | High payroll burden |
| Best For | Early-stage / low volume | $1M+ revenue or multi-entity |
If your books lag >15 days, transactions exceed 600/month, or your CPA is complaining, it’s time to upgrade-or outsource.
1. Part-Time Bookkeeping: Flexible but Fragile
Pros
- Lower upfront cost
- Flexible hours or on-demand
- Ideal for early-stage or project-based work
Cons
- No SLAs or review cycles
- Limited availability during close or audits
- One person = single point of failure
- Often reactive (cleanup mode)
When it works: Freelancers, consultants, and micro-businesses with simple transactions.
When it breaks: Once payroll, sales tax, or inventory enter the picture.
2. Full-Time Bookkeeping: Stability, But at a Price
Pros
- Daily posting and reconciliations
- Predictable close schedule
- Easier collaboration with in-house teams
- Immediate answers to internal requests
Cons
- Salary + payroll taxes + benefits
- Recruitment and turnover cost
- Skill plateau (limited exposure to automation)
- You still need a CPA or controller for oversight
Total loaded cost (2025 averages) ≈ $5,500-$6,500/month or $65k-$80k/year with benefits.
Flat-rate monthly team covers the same work for ~$500-$900/month-without payroll risk.

When to Upgrade (Simple 5-Point Test)
| Sign | Impact | Recommendation |
|---|---|---|
| Books more than 2 weeks behind | Cash flow blind spots | Add dedicated resource |
| CPA doing cleanup every quarter | Paying double | Move to full-time or outsource |
| >600 transactions/month | Overload for PT | Scale up or outsource |
| Multiple entities or channels | Complexity spikes | Full-time or managed service |
| Needing forecasts/KPIs monthly | Beyond bookkeeping | Controller-level oversight |
If 3+ signs apply, you’ve outgrown part-time.
