Provider Highlights
Advantages
- 50 years of EOR and contingent workforce operations — the longest track record of any EOR provider in this audit series; unmatched institutional knowledge of US employment law, payroll, and IC compliance
- NPS of 57 vs. industry average 31 — the highest validated customer satisfaction metric in this audit series; a statistical statement that IES clients are exceptional net promoters
- WBENC and WEConnect International diversity certifications — enables procurement teams to capture diversity spend credits; structurally unavailable from most global EOR competitors
- Published transparent pricing: 16% US EOR, $500/month global EOR, 4% AOR — no hidden costs; full pricing published with inclusions listed on the pricing page
- Agent of Record (AOR) with Tax Defense File — purpose-built IC misclassification risk service with dedicated indemnification; unique in this audit series for US contingent workforce buyers
Limitations
- Global EOR uses a hybrid entity and partner network — explicitly stated; service depth outside the US may vary per country; not a fully owned-entity global model
- 16% US payroll markup scales with salary — cost-effective for mid-salary workers; potentially expensive vs. fixed-fee SaaS EOR alternatives for high-salary hires ($15,000+/month gross)
- No G2 review volume — IES is not actively featured in the SaaS EOR procurement review ecosystem; enterprise buyers validate via RFP and reference calls rather than platform reviews
- Service-first, not self-serve SaaS — buyers expecting instant digital onboarding will find the IES model requires consultative sales engagement
- No published HRIS integration list, no confirmed crypto payroll, no equity/ESOP administration
Platform Features & Capabilities
Employer of Record (EOR) — US and Global
IES manages compliant employment across all 50 US states and 150+ countries globally. US EOR at 16% markup covers: all federal and state payroll taxes (FICA, FUTA, SUTA, Medicare), Workers' Compensation, business insurance, HR support, compliance monitoring, and payroll funding — all in a single transparent fee. Global EOR at $500/month starting management fee covers payroll processing, business insurance, HR support, compliance, consolidated invoicing, and partner network management for international markets. A hybrid model of own entities and partner networks is used for global coverage — buyers should confirm the specific model for their target countries. 0 worker misclassifications ever and 100% client audit compliance rating are cited operational performance records.
Agent of Record (AOR) — IC Compliance
The AOR service is IES's most distinctive US-specific product — purpose-built for independent contractor compliance risk management. At 4% on the IC invoice, AOR covers: classification evaluation, compliant contracting and indemnification, invoice consolidation, the proprietary Tax Defense File (documentation protection in IRS or state audits), tax form issuance (1099), and ongoing compliance advisory. This is a unique capability in this audit series. For US companies managing significant independent contractor workforces, the IC misclassification risk is a material legal exposure — IES's AOR with Tax Defense File provides a structured compliance defence that generic EOR platforms do not offer.
ies.WorkSite Platform
The ies.WorkSite proprietary platform is accessible via desktop and a dedicated mobile app. Confirmed features: onboarding progress monitoring; active assignment management; key metrics and KPIs reporting in multiple formats; real-time compliance monitoring; built-in VMS/MSP integrations for procurement-led programmes; consolidated billing visibility; talent pool management for contractor re-engagement; and an employee self-service dashboard in 125+ languages. Support is available via the platform through phone, email, chat, text, and WhatsApp. People Managing People reviewers note the user-friendly onboarding tools and mobile accessibility as strengths. No HRIS integration list (Workday, BambooHR, SAP) is published.
Full Contingent Workforce Lifecycle
IES is the only provider in this audit series offering the complete contingent workforce lifecycle as a bundled service: EOR (full-time converted workers and direct hires), AOR (IC compliance), Direct Sourcing (talent identification and pipeline), Back Office Support (white-label back office for staffing firms and independent recruiters), and Strategic Workforce Consulting (programme design, compliance strategy, and market entry). For staffing firms wanting to expand into contract placements without building their own back office, IES provides a direct partnership model. For procurement-led enterprises with complex contingent workforce programmes, the combination of EOR + AOR + VMS integration + diversity certification is uniquely comprehensive.
What Users say
NPS 57 — The Most Significant Satisfaction Signal
The published NPS of 57 versus an industry average of 31 is the single most compelling client satisfaction metric in this audit series. NPS measures the proportion of active promoters minus detractors — a score of 57 in a market where the average is 31 means IES has structurally more clients who actively recommend it than any average competitor. No other provider in this series has a published NPS that can be directly benchmarked. Buyers can treat this as a validated statistical statement rather than a selected testimonial.
Client Testimonials — Long-Term Relationships
IES testimonials consistently reference multi-year and even multi-decade relationships — a signal of operational consistency that no startup EOR can claim. One reviewer describes 30+ years of experience across all industries and specifically names IES as the most excellent company encountered. Another describes a 50%+ reduction in administrative time. A third describes daily contact with IES and consistently receiving service that goes above and beyond. The depth of these endorsements, combined with the 30-year client relationships IES cites, is not replicated in any other provider in this series.
Compliance Record
Two compliance performance metrics are cited on the IES website: 0 worker misclassifications ever across 50 years of operations, and 100% client audit compliance rating. For enterprise buyers in the US where IC misclassification carries IRS, state tax authority, and Department of Labor risk — these are the most relevant performance metrics for EOR selection. No third-party auditor is named for these claims, so buyers should specifically ask IES to provide documentation or references that support these figures.
Employee Culture — 10+ Years Best Places to Work
IES has been named one of San Diego's Best Places to Work for 10+ consecutive years. Glassdoor reviews describe strong culture, leadership transparency, work-life balance emphasis, and professional development investment. For buyers who view the quality of the EOR provider's own employment culture as a proxy for how they will treat client-side employees and contractors, this is a meaningful signal — and a rare one at this consistency level.
OUR TAKE
Is IES the Right EOR for You?
IES occupies a unique and strongly defensible position: the most compliance-proven, relationship-driven, 50-year contingent workforce EOR specialist with the highest published NPS score in this audit series. For US-centric companies managing complex contingent workforces across states and select global markets, IES is arguably the safest, most validated choice available — backed by a track record no startup EOR can replicate. Three evaluation steps: confirm the entity vs. partner model for your specific global target countries, model the 16% markup against fixed-fee alternatives at your expected salary levels, and request a WorkSite demo specifically for your VMS/HRIS integration requirements. The NPS of 57 is a powerful endorsement — but speak to a reference client in your industry before signing. Use our free comparison tool to see how it stacks up for your specific needs.

Latest news & updates
2024 — 50th Anniversary
IES celebrated its 50th anniversary in 2024 — a milestone no other EOR provider in this audit series has reached. The anniversary reinforces the company's position as one of the oldest and most operationally experienced EOR operators in the contingent workforce market, with compliance records and client relationships spanning half a century.
2024 — Inc. 5000 (Third Consecutive Year)
IES was named to the Inc. 5000 list for the third consecutive year in 2024, reflecting 132% three-year revenue growth. This commercial momentum, alongside the 50-year operational track record, validates that the business continues to grow rather than consolidate — a signal of market demand for its contingent workforce specialisation model.
Ongoing — San Diego Best Places to Work (10+ Consecutive Years)
IES has maintained Best Places to Work recognition in San Diego for over 10 consecutive years — an extraordinary employer culture signal that directly correlates with the NPS of 57. Companies with strong internal cultures consistently deliver better client-facing service quality; IES's decade-plus recognition is a structural confirmation of this relationship.
Frequently asked questions
Questions about the EOR Provider.
Still have questions?
Ask our team and get clear, unbiased guidance tailored to your situation.
How much does IES EOR cost?
IES publishes all pricing. US EOR: 16% markup on gross payroll (all-inclusive for statutory taxes, payroll processing, Workers' Comp, HR support, compliance). Global EOR: $500/month management fee starting, with country-specific statutory costs added. AOR: 4% on the IC invoice including Tax Defense File. Benefits, background checks, and visa support are optional add-ons. Model the 16% markup against fixed-fee SaaS EOR alternatives at your expected salary levels before committing.
What is WBENC certification and why does it matter?
WBENC (Women's Business Enterprise National Council) certification verifies that IES is at least 51% owned and operated by a woman. Many large corporations and government procurement programmes require a percentage of spend to be allocated to certified diverse suppliers. Using IES as your EOR provider enables your organisation to count that spend toward diversity programme requirements — a benefit structurally unavailable from most global EOR competitors.
What is the AOR service?
Agent of Record (AOR) is IES's independent contractor compliance service. At 4% on the IC invoice, it covers: contractor classification evaluation, compliant contracting, indemnification, invoice consolidation, the proprietary Tax Defense File (audit defence documentation), 1099 tax form issuance, and ongoing compliance advisory. For US companies managing IC workforces where misclassification creates IRS and Department of Labor risk, the AOR with Tax Defense File is a unique compliance protection not offered by standard EOR providers.
Does IES have a mobile app?
Yes. The ies.WorkSite platform is available via a dedicated mobile app in addition to desktop access. The employee self-service dashboard operates in 125+ languages, enabling multilingual employee access to payroll records, onboarding documents, and timecard submission.
How does IES handle global EOR?
IES covers 150+ countries for global EOR via a hybrid model of own entities and partner networks — explicitly stated on the EOR services page. Service depth outside the US may vary by country. The $500/month management fee is the starting rate to which country-specific statutory contributions are added. Buyers should confirm the specific entity vs. partner model for their target countries during evaluation.

Switching to or from Innovative Employee Solutions?
Switching to IES
IES provides a consultative onboarding process for companies migrating from another EOR or transitioning workers from direct employment or freelance arrangements. The WorkSite platform onboarding module tracks progress for each worker across all active states and countries. For US-based migrations, the 16% markup model activates at the first payroll run — confirm any in-process payroll obligations with your prior provider before initiating the transition. For IC compliance migrations (AOR), the classification evaluation and Tax Defense File setup run in parallel with worker contracting. Request a VMS/MSP integration assessment if your procurement organisation uses a vendor management system — IES confirms VMS integration capability but specific connector compatibility should be verified.
Switching away from IES
When transitioning away from IES, confirm the contractual notice period and request full data exports from ies.WorkSite: payroll records, state and federal tax filing archives, Workers' Compensation records, IC classification files and Tax Defense File documentation, and timecard and assignment records. For global EOR clients, obtain country-specific compliance records per worker. For AOR clients, specifically request the Tax Defense File documentation — this is audit-defence material that must be transferred to maintain protection if an IRS or state audit occurs after the transition. Given IES's 50-year client relationships, long-term clients should also confirm any multi-year agreement terms before initiating a switch.
Questions to ask before switching any EOR
Before switching to or from any EOR provider, confirm: Will there be a gap in employment or benefits coverage? Who handles employee communication during transition? Are there overlapping billing periods? Will payroll history transfer in a usable format? Are there state-specific restrictions on payroll provider changes?
