Whether you call it invoice management, a app for jobs, or a invoicing system — most private investigators in Champaign string together FreshBooks, QuickBooks, Toggl Track along with other platforms. That's $972/year in tool subscriptions. Within 5 years at today's prices, the total damage is $4,860.

One drag generates an invoice. No duplicate data entry. No middleware. No integration tax. It's a one-time purchase — eliminate recurring fees from the first day.

Most of my cases come from attorneys, insurance companies and individuals, and every case starts with a clear objective and a check that it's legal and ethical, because some requests I turn down. Background investigations mean public records, court filings, property and business records, and interviews, pieced together into a report. Surveillance is long, uncomfortable work: hours in a vehicle, watching and documenting activity with photos and video, noting times precisely, and staying unnoticed, often for insurance claims where someone's claimed injury doesn't match their weekend. Locating people, witnesses or debtors, is detective work through records and contacts. Everything I do has to stand up in court, so my notes, the chain of custody for evidence and the report are meticulous, and I may be called to testify. I know the laws on recording, trespass and privacy in my state and stay well inside them. I'm licensed and insured, bill by the hour plus mileage and expenses, and take a retainer before I start a case.
That is the work Nexa is built around: the job, the client, the hours and the invoice live in one place, so the paperwork side of the day doesn't need a second shift.
Every one of those was bought once and earns its keep for years. Nexa is priced the same way: $279 once, and it keeps working whether business is busy or slow.

Open on Reddit →We build a private investigator's guide the same way every time, and we'd rather you trust it than take it on faith. Nexa is our product, so the test we hold ourselves to is simple: a tool only "wins" a job here when it genuinely does that job better for a private investigator — and where something free, open-source, or buy-once does it better, we say so and link you to it. Where Nexa falls short (payroll is the honest example), we name the alternative outright.
