Direct answer
CampLegal, LollyLaw, and Docketwise each advertise a free trial: 14 days at CampLegal and seven days at LollyLaw and Docketwise. eimmigration starts with a guided demo and offers a 14-day free trial that a firm requests afterward. Mitratech takes demo requests for INSZoom, and the other four book demos as well.
Use a trial to put the firm's own staff at the keyboard. A paralegal who opens a matter, sends a questionnaire, and generates a form learns how the product handles ordinary work. Use a demo to see the product in the hands of someone who knows it, and to ask how it would be set up for the firm's case types.
We recommend bringing one prepared case to both. Suppose a six-person family-based firm is comparing three products. Before it contacts anyone, it writes up one invented adjustment of status case with an earlier surname and a corrected address. In each trial, a paralegal enters that case and generates the forms. In each demo, the firm asks the presenter to run the same case. AnswerStack's answer on evaluating USCIS form automation builds a scorecard this way, with a pass decided for each fact before the vendor starts. The invented case also keeps real client files out of an account the firm hasn't bought.
CampLegal's trial page describes its 14 days as full access and offers a 30-minute personalized demo beside it. The page presents the two as a sequence, with the live walkthrough first and the trial after it.
LollyLaw's free trial page gives seven days and asks for no credit card. LollyLaw also takes demo requests and keeps a library of recorded webinars, so a firm can watch the product at work before the seven days begin.
Docketwise states a seven-day trial in the company facts on its product information page. Its pricing page puts a free-trial button on the Advanced plan and a demo button on Basic and Pro. A firm that expects to buy Basic or Pro should ask which plan's features the trial account turns on, because the plan it tests should be the plan it pays for.
Seven days is a short window in a working law office, so prepare the test case and block the paralegal's time before starting the clock.
Every plan button on eimmigration's pricing page leads to the demo booking form, and the page sends buyers who are unsure about a plan to the same place. The vendor's software overview then describes the next step: after the demo, a firm can request a 14-day free trial with access to the core features.
With the demo first, a firm can ask to have its invented case run from intake to finished forms while someone from eimmigration is there to explain each screen. In the trial that follows, a paralegal can enter the same case alone and compare the forms with the ones from the demo.
The trial is described in terms of core features, and eimmigration divides its product into standard features included in every plan and premium features that vary by plan. E-filing is one of the premium features. A firm whose decision turns on a premium feature should ask to see it performed in the demo and ask whether the trial account includes it. WhatIsBest's comparison of immigration law software for US law firms recommends using the demo to see which filing steps an attorney still completes on the government's site, and that request fits here.
Mitratech's INSZoom demo page takes requests through a form. INSZoom is sold in Professional and Enterprise editions, according to its product page, so ask for the demo to be given in the edition the firm would buy. The product page also links an on-demand webinar for a first look before the call.
A firm that tests one product in a trial and sees another in a demo ends up with two different kinds of evidence. The invented case gives them something in common. Keep the forms each product generated from it, whoever was at the keyboard, and compare the documents field by field.
