OnPay
Pros
- + One plan with everything in it: at time of writing $49 base + $6/worker/month covers payroll, tax filing in all 50 states, direct deposit and the HR toolkit (onpay.com/Payroll)
- + Per-worker fee applies once per month no matter how many pay runs — weekly payroll does not multiply your bill
- + Tax accuracy guarantee: OnPay covers penalties and interest on filing errors it makes
- + Free setup and migration with human help, which is the hard part of switching payroll providers
- + Accountant-friendly: multi-client dashboard, filterable custom reports and accounting exports with no integration fees
Cons
- - US-only — no international payroll, EOR or contractor-of-record capability
- - Benefits administration without a shopping layer: no marketplace to compare plans, you source your own carrier
- - HR features are basic (onboarding, PTO, documents) — not a full HRIS with recruiting or performance cycles
- - No native time clock; you integrate TSheets, Clockify or similar (third-party review, smbhrreviews.com)
- - Published base price conflicts across sources ($40 in older reviews vs $49 on the vendor site) — confirm current pricing before budgeting
GPT for Sheets and Docs
Pros
- + Cell-level functions (GPT, GPT_TRANSLATE, GPT_EXTRACT, GPT_CLASSIFY) process thousands of rows independently, and in my 500-row test a deliberately exhausted credit balance reported the run as interrupted while preserving per-row success/failure counts
- + Pay-as-you-go to subscription economics with $25/month Standard including $25 of usage and shared extra-usage pools on Business at $45/seat — no per-seat AI lock-in for spiky agency workloads
- + Enterprise plumbing is real: ISO 27001 certification, SAML SSO on Enterprise, BYOK/custom endpoints, zero-data-retention options and a stated no-training policy (vendor documentation)
- + Model breadth across OpenAI, Anthropic, Google and others, with Autosheet MCP (shipped August 2026) letting Claude or ChatGPT drive the spreadsheet agent from an external client
- + Detailed usage reporting maps credit spend to tokens and requests, so I could price each bulk column before committing to a run
Cons
- - No permanent free tier: the trial credits run on a single model, so the multi-model selling point cannot be evaluated without subscribing ($25/month at time of writing)
- - Docs usage billing is not explained on the pricing page, which covers Sheets and Excel plans only
- - The mid-2026 rebrand to Autosheet means listing names, website and docs disagree for now — a mild tracking burden for buyers
- - Multi-account Google sign-ins trigger documented authorization errors; Workspace admins must allow add-on execution
- - The sidebar agent writes formulas but does not reason about cross-sheet business logic — tasks execute, outcomes are still yours to verify
