Short answer
Modernize in the order the data flows: fix census and payroll intake first, give every plan a single record that testing, filings and billing read from, track the plan year as projects with dated deadlines, and only then decide whether to replace core systems. Measure re-keyed hours before and after each step.
Start with a measurement, not a product demo
Most independent TPAs already know where the pain is: year-end. What they rarely have is a number. Before looking at any software, spend two weeks recording where staff time goes on a sample of plans. Three figures matter most:
- Re-keyed fields: how many times the same data (participant counts, compensation, contribution totals) is typed or pasted into another system.
- Chasing time: hours spent requesting, reminding and clarifying census and payroll data from sponsors.
- Rework: how often testing or a Form 5500 is re-run because the data changed after it started.
These numbers tell you what to automate first and let you prove later that it worked.
Fix data intake first
Every downstream process inherits the quality of the census and payroll data. A missing hire date affects eligibility, an incorrect date of birth affects catch-up eligibility, and a rehire coded as a new hire affects vesting. Modern intake has four parts:
- A sponsor template or a mapped payroll export, so data arrives in a predictable shape.
- Validation rules run on arrival: required fields, duplicates, plausibility, eligibility and annual limits.
- An exception queue where each failed row shows the field, the rule and the reason, and staff record the fix.
- Year-over-year comparison that flags employees who disappeared, reappeared or changed key dates.
This step alone often removes the largest share of chasing and rework, and it is useful whatever core system you keep. See contribution and payroll processing.
Give every plan one record
In many practices, plan facts live in several places: the testing package, the document system, a billing spreadsheet, the CRM and people’s memory. A modern setup keeps one plan record (plan type, plan year, effective dates, key provisions, contacts, fee schedule, service agreement) that other tools read from. When a provision changes, it changes once, with a date and a note.
Run the plan year as projects with dated deadlines
Treat each plan’s annual cycle as a project with tasks, owners and due dates, generated from a template for the plan type. A compliance calendar should date each plan’s deadlines, such as corrective distribution deadlines after a failed ADP or ACP test and the Form 5500 due date (the last day of the seventh month after the plan year ends, extendable with Form 5558). Owners then see which plans are at risk weeks ahead, rather than discovering it in the final week.
Connect testing, filings and billing
Once intake and the plan record are reliable, connect the outputs:
- Testing runs on the validated census, and results are stored with their inputs.
- Form 5500 data (participant counts, contributions, assets) is aggregated from the same records.
- Billing reads the plan’s fee schedule and participant counts, so invoices match the work.
Whether these are modules of one platform or separate tools joined by integrations matters less than the rule that data is entered once.
Then decide about the core system
| Option | Good fit | Watch out for |
|---|---|---|
| Keep and extend | Your testing or administration package works; pain is around it | Integration limits of the package and its license |
| Replace with a commercial platform | Standard plans, appetite to adapt processes | Migration effort, vendor hosting model |
| Integrated customer-hosted platform | You want one system you control | Maturity of the product; run a scoped pilot |
| Custom build | Your process is a differentiator | Long-term ownership of rule updates |
Software Home builds around existing platforms and also develops KinetiPlan, an integrated platform for independent TPAs, so we have an interest in this choice. A scoped pilot on your own data is the fairest test of any option.
People and change
Modernization fails more often on adoption than on technology. Involve the analysts who run year-end from the first design session, migrate one plan type before all of them, keep the old process available until the new one has been through a full cycle, and publish the before-and-after measurements to the team.
