The assumption is that bundling payroll and TPA eliminates errors. In reality, it often hides them until it\u2019s too late.<\/p>\n<p>One System, One Interpretation, One Point of Failure<\/p>\n<p>When the same provider runs payroll and administration, everything flows through a single system and a single interpretation of the plan document. That sounds efficient, until the setup is wrong. If eligibility is coded incorrectly or compensation definitions don\u2019t align with payroll fields, the error repeats every pay period. There\u2019s no independent TPA catching the issue because the same entity created it. What looks like integration is often just duplication of risk.<\/p>\n<p>Plan Design Still Has to Fit the System<\/p>\n<p>Sponsors assume the bundled provider will translate the document into something workable. That\u2019s not how it works. The system is built to handle standard designs. Once you layer in complex eligibility, non-standard compensation, or nuanced matching formulas, you\u2019re relying on configuration, not expertise. If the design doesn\u2019t match how payroll actually runs, the system won\u2019t fix it. It will process it wrong, consistently.<\/p>\n<p>Delegation Doesn\u2019t Change Liability<\/p>\n<p>The biggest misconception is that bundling services shifts responsibility. It doesn\u2019t. Under ERISA, the plan sponsor owns the result. When errors happen, it\u2019s the sponsor writing the check for corrective contributions and explaining it to participants. The provider may help fix it, but they\u2019re not absorbing the liability. That\u2019s the part no one focuses on during the sales process.<\/p>\n<p>By the Time You Call, It\u2019s Cleanup<\/p>\n<p>By the time the issue surfaces, it\u2019s already expensive. Now we\u2019re talking about corrections, earnings, notices, and time spent unwinding months or years of bad data. The fix isn\u2019t finding a better cleanup process. It\u2019s making sure the plan design actually works within the system before it ever goes live. Because when payroll and TPA are the same shop, there\u2019s no second set of eyes coming to save you.<\/p>\n<p><span class='st_sharethis' st_title='{title}' st_url='{url}' displayText='ShareThis'><\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>The most expensive calls I get usually start the same way. \u201cOur payroll provider handles the TPA work too, and something went wrong.\u201d Contributions were missed, eligibility was misapplied, or the match didn\u2019t follow the document.
