What Separate Bookkeeping, Tax, and Payroll Providers Are Really Costing You
A couple of posts back, I broke down what a bundled monthly plan actually costs by business size. The number people usually want to compare it against is what they’re already paying for a bookkeeper, a payroll service, and a tax preparer separately. That comparison is worth doing, but the real cost of a fragmented setup usually isn’t the line items. It’s what falls through the cracks between them.
The Direct Cost Often Isn’t That Different
Add up a standalone bookkeeper, a payroll service, and tax prep spread out over the year, and the total often lands close to what a bundled monthly fee would cost for the same size business. A solo bookkeeper alone can run $300 to $800 a month, a payroll service typically charges a base fee plus $6 to $10 per employee per month, and standalone tax preparation for a small business return commonly runs $800 to $2,500 a year depending on complexity. Once you add those up, the sticker price gap between “separate” and “bundled” is often smaller than people expect.
The Real Cost Is in the Gaps
Where separate providers actually cost you money is in what happens when none of them are talking to each other. Your bookkeeper doesn’t know what your tax preparer needs until it’s too late to fix it cleanly. Your payroll service doesn’t flag that a contractor crossed the $600 threshold and needs a 1099. Your tax preparer only sees your numbers once a year, after the decisions that would have saved you money are already behind you.
A few concrete examples of what that actually costs:
Missed or late 1099s. The IRS penalty for filing a 1099 more than 60 days late, or not filing it at all, is $340 per form as of 2026, and that climbs to $680 per form if it’s deemed intentional disregard, with no cap. A business that paid five contractors and missed the filing isn’t looking at a rounding error, it’s a real, avoidable penalty.
Rebuilt or re-explained books. When your tax preparer gets a file they didn’t build and don’t fully trust, they spend billable time reconciling it before they can even start the return. That time often shows up as a higher invoice, a longer turnaround, or both.
Missed deductions. A bookkeeper who doesn’t know how your business is taxed has no reason to categorize things the way your return actually needs them categorized. That disconnect is one of the most common ways small businesses quietly overpay.
Your own time. Coordinating between three vendors, three logins, and three points of contact is itself a cost, even when nothing goes wrong. It’s time you’re not spending running the business.
What a Bundled Setup Actually Prevents
None of this means separate providers are always the wrong choice. But when bookkeeping, payroll, and tax prep are handled by the same team working from the same numbers all year, the kinds of errors above mostly stop happening, not because any one piece got cheaper, but because the gaps between the pieces closed.
