Signs It's Time to Evaluate ADP
Common triggers that bring businesses to ADP through Certum
These are the situations our partner manager specifically flagged as ideal moments to evaluate ADP. If any apply to your business, a free consultation is the right next step.
Wanting to offer 401(k), health, or benefits for 2026
ADP handles plan selection, enrollment, and benefits administration — removing the complexity of offering benefits as a small employer.
Deduction & Compliance Review
Monthly review of transactions for potential deductions and IRS compliance; not just data entry, but active oversight.
High medical or workers' comp renewals
ADP TotalSource's group purchasing power often delivers better rates than small businesses can negotiate independently.
Struggling to hire or retain top talent
Competitive benefits packages through ADP TotalSource help small businesses attract employees who'd otherwise only consider larger companies.
Unhappy with current payroll vendor
Price increases, lapses in service, or poor support from Gusto, Paychex, or QuickBooks Payroll. 9 out of 10 businesses prefer ADP after switching.
New business or year-end setup
S-corps and new businesses needing to get set up for payroll correctly from the start — including proper payroll tax registration and setup.
R&D tax credit eligibility
ADP offers a complimentary R&D tax credit assessment. Many businesses don't realize they qualify — and the credit is dollar-for-dollar against payroll tax liability.
The integration most payroll referral partners can't offer
Most businesses that switch to ADP still have the same problem: payroll data and accounting data live in separate systems, and someone has to manually reconcile them. Certum solves that. As a certified QuickBooks Solution Provider and Xero Bronze Partner, we configure ADP's General Ledger Interface so payroll journal entries post to your accounting system automatically— no re-keying, no errors, no monthly reconciliation headaches.
This is what makes Certum different from every other ADP referral partner, we're your accounting team, not just a referral source
Ready to get payroll and bookkeeping working together?
Certum refers you to the right ADP product, coordinates setup, connects payroll to your accounting system, and keeps your books accurate after every run. Free consultation, no commitment.

Yes. ADP's General Ledger Interface exports payroll journal entries directly to QuickBooks Online, QuickBooks Desktop, and Xero without manual re-entry. Certum configures this integration as part of onboarding — mapping ADP payroll categories to your chart of accounts so wages, employer taxes, and deductions post correctly after every run. This eliminates the manual payroll journal entry process that costs most businesses hours each month.
