Get it built for you

A process specialist maps your real gross-to-net flow, integrates time capture, designs the automation around your payroll system and tax/compliance needs, and ships a working build, calculation, tax filing, disbursement and reconciliation, without eroding segregation of duties.

Best for: Teams that want a working result fast and a clean audit trail, not a tool-evaluation project.

Compare payroll software yourself

Vendor-neutral

If you would rather buy and configure a platform, compare the leading payroll tools on footprint fit (SMB, mid-market, enterprise, global), pricing model and verified review counts.

Best for: Teams with internal capacity to run a tool selection and implementation.

The 3 highest-value places to automate

Three levers, each tied to a measured benchmark. The gap between the market average and the best performers is the prize, and most of it sits in these steps.

Time to run payroll
~5 hoursManual
≤15 minAutomated
up to ~90% less time
Time-capture integration + automated calculation

Feeding approved hours straight into an automated gross-to-net engine collapses a multi-hour manual run; ADP reports three in four automated customers finish in 15 minutes or less.

Payroll error rate
~1 in 5Manual (EY)
Caught earlyPre-run check
$291 per error avoided
Automated validation + reconciliation

Automated input validation and pre-run reconciliation remove the manual-keying errors that cost an average of $291 each to correct in the EY survey.

Payroll processing cost
HigherIn-house admin
LowerAutomated
model your own cost
Automated tax filing + outsourced/automated processing

Automating tax calculation, filing and disbursement removes manual administration and penalty exposure; cost per payslip varies widely by market, provider and service model, so use your own provider quote and payroll volume.

What an expert would automate, step by step

  • 1. Collect and approve time: Integrate time-and-attendance / scheduling directly into payroll so approved hours, overtime and PTO flow in without re-keying, removing a leading source of input error (missed or incorrect time punches).
  • 5. Calculate and withhold taxes: Automated tax engines apply current federal, state and local rates and FICA per Form W-4, and many platforms file and remit (Form 941, W-2) automatically, removing manual table look-ups and deadline risk.
  • 7. Reconcile and approve the run: Automated pre-run reconciliation flags outliers, negative net pay and period-over-period variance for review, so a human approves by exception rather than checking every line.
  • 8. Disburse net pay: Direct-deposit / ACH automation and digital payslips replace cheque printing and manual distribution, while keeping disbursement separate from entry and approval.
  • 9. Deposit and file payroll taxes: Scheduled, rules-driven tax deposits and electronic filing meet the IRS monthly/semiweekly deadlines (and the $100,000 next-day rule) automatically, the main way teams avoid failure-to-deposit penalties.

What automating this could save you

Conservative, transparent maths. Drag your numbers and the range updates live. Nothing leaves your browser.

Start from:

$2,964
reclaimable per year

$2,223 to $3,705

78 hours saved per year

≈ 0.0 FTE reclaimed
These defaults are examples. Time-saved per payslip is derived from the ~5-hour manual pay-period benchmark and near-touchless automated processing (Lift HCM / ADP), at a loaded payroll-clerk rate. For payroll the bigger payoff is usually avoiding errors rather than saved minutes: at ~$291 per correction (EY 2022) and roughly 15 corrections a run, error-cost avoidance often outweighs the clerical time saving shown above, and it is deliberately left out of this figure. Replace with your own payslip volume, loaded rate and automatable share for a real estimate. Minutes saved / payslip default: ~3 minutes saved per payslip(Derived from aggregate payroll time savings (Lift HCM / ADP: ~90% reduction, ~5 hrs per pay period); not a per-payslip figure the source states directly, 2024)

Frequently asked questions

Should I build payroll automation or buy a tool?

For standard domestic payroll, a full-service platform (Gusto, QuickBooks Payroll, ADP, Paychex) usually covers it. Have it built for you when you need custom integration (bespoke time systems, multi-ERP GL posting, unusual pay rules) or want a working result fast without a long evaluation.

Which payroll tools should I compare?

Gusto and QuickBooks Payroll (SMB), ADP Workforce Now and Paychex Flex (mid-market/enterprise) and Deel (global / cross-border). Match the tool to your footprint and accounting system first.

How much does payroll automation cost?

Tool pricing ranges from published per-employee tiers (Gusto from $49/mo + $6/person; Paychex Essentials from $39/mo + $5/employee) to quote-only enterprise platforms (ADP). A built-for-you solution is a one-off engagement; use the calculator to weigh either against your payslip volume.
