Process Server Invoicing and Billing App (2026)
Process serving is billed per serve with attempts, rush, mileage, and skip tracing as separate lines, invoiced to law firms that pay on terms against a case number. ShowTheReceipts ($15/mo) saves those as reusable rates, puts the case caption and number on every invoice, bills firms monthly or per job on net terms, and takes card from individual clients up front.
How we picked
Entry-plan prices as published in 2026, taken from each vendor's own pricing page or a recent third-party summary. Judged on the independent server's workflow — per-serve rates with attempt and rush lines, case-referenced invoicing, law firm net terms, and card payment from individuals — not on nationwide service-of-process marketplaces, court e-filing integration, or affidavit automation, which are separate categories.

Attempts are the business
A serve that lands on the first attempt is a good day. The evasive defendant is where the money and the losses both live.
Servers who charge a flat fee with unlimited attempts end up subsidizing the hardest jobs with the easy ones — and the hard ones are exactly the ones that fill your week.

The lines a process serving invoice needs
- Standard serve — flat, covering stated attempts and radius
- Additional attempts — each, beyond the included count
- Rush / same-day service
- Mileage — beyond the included radius
- Skip tracing — flat or hourly
- Stakeout / surveillance hours
- Court filing and pickup
- Notarization and document prep
- Non-service affidavit — the job you did that didn’t land
Bill the non-service
A defendant who can’t be found still cost you three trips. A non-service affidavit is a real deliverable — attempts documented, times logged, address confirmed vacant.
Servers who eat those jobs are working for free on the exact outcomes they had the least control over.
Firms pay on process, not goodwill
Case caption, case number, party, dates. Invoice a firm the way their billing clerk needs to code it and you get paid on terms; leave the case reference off and your invoice just sits there waiting for a human to reconstruct it.
Frequently asked questions
How should a serve be priced?
A flat rate covering a stated number of attempts within a radius, then attempts, rush, mileage beyond the radius, and skip tracing as add-ons. Flat-with-adders is what law firms expect and what makes an evasive defendant profitable instead of ruinous.
What has to be on an invoice to a law firm?
The case caption, case number, party served, and dates of attempts. Firms bill your fee through to their client, so an invoice missing the case reference can't be coded and sits in a pile until someone chases it.
Should individuals pay up front?
Yes — card at intake, before the first attempt. Firms are repeat clients with a payment process; individual clients are a one-time transaction, and collecting after a serve that didn't go their way is the hardest money in this trade.
Do I need affidavit automation software?
It's genuinely useful and it's a different job from getting paid. If your problem is 60-day law firm receivables and unbilled attempts, fix the billing side first — the affidavit was never the bottleneck.
