Private investigator service packages vary wildly depending on what you're investigating—and knowing what you're actually paying for makes a massive difference. Whether you need background checks, surveillance, or asset location, understanding what's included (and what costs extra) helps you avoid surprise invoices and choose the right firm for your case.
What's in a Standard PI Package?
Most private investigators bundle their core services into tiered packages rather than charging à la carte. A basic package typically includes:
- Initial case consultation and strategy discussion
- Background research and public records review
- Database searches (criminal history, civil records, property ownership)
- Standard report documentation with findings
- 5–10 hours of investigative work (varies by firm)
Expect to pay $1,500–$3,500 for an entry-level package that handles straightforward cases like basic background checks or locating someone. Mid-tier packages run $3,500–$7,000 and add surveillance hours, deeper financial investigation, and witness interviews. Premium packages start at $7,000+ for complex cases requiring multiple investigators, extended surveillance, or international research.
Surveillance and Field Work
This is where costs escalate quickly. Surveillance typically charges $75–$150 per hour depending on the investigator's experience and your location (urban areas are pricier). A standard surveillance package usually includes:
- 20–40 hours of monitored observation
- Photo or video documentation
- Daily written reports
- GPS tracking (if legally applicable in your jurisdiction)
If your case requires weekend or overnight surveillance, expect a 25–50% premium. Many firms require a minimum deposit of $1,500–$2,500 upfront before surveillance begins, with additional hours billed as they're used.
Background and Financial Investigation
These services dig into public and semi-public records. A comprehensive background check package ($500–$1,500) typically covers:
- Full criminal history (state and federal)
- Civil litigation records
- Employment and education verification
- Bankruptcy and financial filings
- Property ownership and tax records
- Social media and online presence review
Financial investigation packages ($2,000–$5,000+) go deeper: tracing hidden assets, analyzing bank records, identifying business interests, and locating offshore accounts. These require more investigator time and specialized expertise, which is why they cost significantly more than basic checks.
Skip Tracing and Locates
If you need to find someone, skip tracing services locate people by analyzing phone records, utility connections, known associates, and database searches. A standard locate package runs $500–$1,500 and typically guarantees results within 2–3 weeks. Faster locates (5–7 days) cost 20–40% more. Complex cases involving someone actively hiding cost $2,000–$4,000+ and may require field work.
What Usually Costs Extra
Read the fine print. Most firms charge additional fees for:
- Database access fees ($50–$300 per report)
- Witness interviews beyond the package hours ($75–$150 per hour)
- Court testimony or deposition prep ($150–$300+ per hour)
- International investigation ($2,000–$10,000+ depending on country)
- Drone surveillance or specialized equipment ($500–$2,000 per day)
- Travel and mileage (typically $0.50–$1 per mile plus meals)
- Expedited turnaround (20–50% rush fee)
How to Compare Packages
When evaluating investigators or firms through platforms like Mercoly, where you can compare and find trusted private investigators in one place, ask these specific questions:
- What's the hourly rate, and how many hours are included? Some firms quote a flat fee but use cheap rates to justify low hour limits.
- What databases do they access? Firms with access to skip-tracing databases and court records networks produce better results faster.
- Are there hidden fees? Request an itemized estimate that lists every potential charge, not just the base package price.
- What's your refund or satisfaction guarantee? Legitimate firms stand behind their work.
- How experienced are their investigators? Someone with 10+ years and relevant specialization (family law, corporate, etc.) justifies premium pricing.
Timeline Expectations
Most investigators complete basic packages within 2–4 weeks. Surveillance cases take longer because you're waiting for specific behavior to occur. Complex financial investigations can stretch 6–12 weeks. Always ask about timelines upfront—if an investigator guarantees instant results, that's a red flag.
Frequently Asked Questions
Q: What's the difference between a flat-fee package and hourly billing? Flat-fee packages give you predictable costs but may limit investigation depth, while hourly billing is transparent but potentially open-ended. Choose flat-fee for straightforward cases and hourly for complex investigations where scope might expand.
Q: Do I need a lawyer to hire a private investigator? No, but having one review contracts and findings (especially for legal cases) protects you. Many investigators work directly with individuals for personal matters like background checks.
Q: Are private investigator reports admissible in court? Only if the investigator testifies and follows proper evidence-handling procedures. Ask whether a firm's package includes court-ready documentation before hiring.
