TandemLink exists because keeping payroll and benefits in step across dozens of employer groups is real, repetitive work — and nobody had time for the spreadsheet rebuild every cycle.
One platform, every client — isolated per group.
Pulls from your payroll vendor, whichever it is.
Your benefits administration platform stays canonical.
Every architectural choice — per-client column maps, replacement-merge defaults, PHI minimization, the operator action queue, the deduction reconciliation pipeline — exists because running it in production needed it, not because someone designed it on a whiteboard. If your team keeps ending up in the import wizard on a Tuesday morning, you're our buyer.
Every employer's payroll export mapped once, reused every cycle.
Predictable writes — the source stays authoritative.
Only the data a sync needs ever moves or is stored.
Humans step in only on what the bot shouldn't resolve alone.
Benefit deductions checked against the source, every run.
We onboard a few firms at a time — hello@tandemlink.net
