i9 Intelligence vs. ADP

ADP runs payroll for a huge share of US employers, and its I-9 is an add-on to ADP Onboarding, sold separately. It leaves ICE audits, remote Section 2, and the hard document cases with your HR team. i9 Intelligence is compatible with ADP, so payroll stays in ADP and the I-9 goes to the team that has done nothing else for 28 years.

The I-9 is an add-on to a payroll system

ADP is a payroll company first, and its I-9 lives inside ADP Onboarding, where ADP's own Marketplace listing says the I-9 is sold separately. That makes it one form among direct deposit, tax withholding, and company policies, supported by teams whose main job is payroll. The ADP customers we talk to describe the I-9 problems that follow from that setup. Remote hires get a Section 2 nobody is sure how to finish, new hires who can't get through the onboarding portal end up in the office anyway, and I-9s end up split between ADP, paper, and older systems.

When ICE asks for your I-9s

A Notice of Inspection gives an employer at least three business days to produce its Forms I-9 (8 CFR 274a.2(b)(2)(ii)). What matters then is whether every form is complete and correct, whether the audit trail holds up, and whether someone who has been through an inspection is on your side. ADP stores your electronic I-9s, and the review, the corrections, and the conversation with ICE stay with you and your attorney. Our compliance team has helped employers through ICE audits since 1998. We pull your I-9s, review them with you before they go out, and help you correct what the rules allow. Our account reviews also flag open Section 2s, unresolved E-Verify cases, and forms past their retention date long before an audit.

Who answers the hard questions

The questions behind most I-9 violations aren't platform questions. A TPS holder whose country's designation was terminated or extended this year, an asylee or refugee presenting a Form I-94 instead of a card, a work permit covered by an automatic extension, a receipt, or an expiring document that has to be reverified on Supplement B all need someone who knows the rules. ADP's support is built around payroll and HR. Calls to us go to the I-9 compliance team, who have handled exactly these cases since 1998.

The I-9s you already have

Changing I-9 systems doesn't end your duty to the old forms. Under 8 CFR 274a.2(e)(4)(ii), existing Forms I-9 have to stay in a system that remains fully accessible for as long as each one must be kept. We migrate older ADP and paper I-9s into i9 Intelligence, including older form editions, Supplement B history, and the audit trail, so every form sits in one searchable place with its retention date tracked. If you'd rather leave the ADP forms where they are for now, new hires can start in i9 Intelligence right away and the older forms can move later.

Remote hires

ADP doesn't supply anyone to examine documents, so a remote hire means naming an authorized representative near the new hire or reviewing documents yourself over live video under the DHS alternative procedure, which requires E-Verify (USCIS). On i9 Intelligence, a manager or representative you choose completes Section 2 at no extra cost, or our US-based compliance team does it by video. For how new hires get from ADP to us, see our guide to the HRIS integration gap.

Where ADP is stronger

Every comparison we publish includes this. If one of these matters most to you, ADP may be the better fit.

  • Payroll, benefits, time, and onboarding come from one vendor, with a large Marketplace of add-ons.
  • Payroll and HR share one login, and ADP has packages for every size, from RUN for small businesses to Vantage for large enterprises.

Keep ADP. Add i9 Intelligence.

ADP runs payroll and HR while the Form I-9 and E-Verify run in i9 Intelligence, with a compliance team behind them. New hires can be added directly or come over from ADP through our API, and we can bring your older ADP and paper I-9s over so every form lives in one place.

Common questions

Does ADP do I-9 and E-Verify?

Yes. ADP offers an electronic I-9 inside ADP Onboarding, which its Marketplace lists as sold separately, and E-Verify through its I-9 service. i9 Intelligence submits E-Verify cases natively from the completed I-9 and sends reverification alerts at 180, 90, 60, and 30 days, with a compliance team behind every case.

How does ADP fit with i9 Intelligence?

i9 Intelligence is compatible with ADP. ADP runs payroll and HR, and i9 Intelligence runs the Form I-9, E-Verify, and remote Section 2. New hires get added directly or come over from ADP through our API, which is included on every plan.

Who completes Section 2 for a remote hire on ADP?

ADP's guidance is to name an authorized representative, such as a notary or another person near the new hire, or to use the DHS alternative procedure, where someone on your team reviews the documents over live video. The alternative procedure is only open to employers enrolled in E-Verify and in good standing. On i9 Intelligence, our US-based compliance team can complete Section 2 by video, or a representative you choose can do it at no extra cost.

Will ADP help if ICE audits our I-9s?

ADP stores your electronic I-9s and can produce them, and the review, corrections, and response to ICE stay with you and your attorney. i9 Intelligence has helped employers through ICE audits since 1998, reviewing I-9s before they go to ICE and helping correct what the rules allow.

Is ADP's I-9 enough for some employers?

It can be. Some HR leaders tell us ADP's I-9 has worked better for them than other HR systems they've used, especially for employers who hire in person and have experienced HR staff. Remote hires, frequent document questions, and years of paper or older I-9s are usually what bring ADP employers to us.
