Tax season is many things: long hours, back-to-back deadlines, a sprint that demands everything your firm has. But it’s also a magnifying glass. Whatever isn’t working in your day-to-day operations gets amplified when the pressure is high and there’s no margin for error.
For many accounting professionals, what keeps surfacing is mailing.
Not the concept of sending documents—that’s unavoidable. But the process around it: the mailing trips, the postage guesswork, the time spent away from clients to handle something that shouldn’t take that long. Stamps.com surveyed 500 professional services workers, including accounting and bookkeeping professionals, to understand how mailing fits into their workweek. The results were telling.

Nearly half—41%—of accounting professionals surveyed have postponed client-facing work due to admin or mailing backlogs in the past month. In a profession where every hour of client time has a dollar value attached to it, that’s a significant drain—and it’s happening before a single deadline is even at risk.
The stress doesn’t stop at the office, either. More than half of accounting professionals surveyed said administrative tasks regularly cut into their personal time. During tax season, that probably feels expected. But the data suggests it’s happening year-round, not just in March and April.
And then there’s postage. Nearly 6 in 10 accounting professionals reported overpaying for postage because they weren’t sure of the correct rate. They’re not overpaying out of ignorance. They’re overpaying because the process doesn’t give them a better option.
Accounting firms have modernized a lot in recent years. E-signatures, digital invoicing, cloud-based bookkeeping—these tools have changed how the work gets done. But mailing for accounting firms has largely stayed the same.
Among accounting professionals surveyed, invoicing (52%), bookkeeping and expense tracking (35%), and appointment scheduling (35%) have all seen strong digital adoption in the past two years. Mailing trails all of them—fewer than 1 in 10 accounting professionals have modernized their mailing process.

The gap is striking. Firms that have modernized nearly every other workflow are still sending someone on a mailing trip to handle tax documents and client filings. It’s not because mailing is unimportant—it’s often because it’s been treated as something to absorb rather than something to fix.
That logic changes during the busy season. When nearly half of accounting professionals send time-sensitive documents daily or several times a week, a process that depends on being in the right place at the right time isn’t a process at all.
The consequences of an unreliable mailing process are real and specific for accounting firms. Tax filings that require wet signatures, certified documents sent to the IRS, copies of returns mailed to clients—these aren’t discretionary. They have to go out, and they have to go out on time.
Across accounting professionals surveyed, 77% have experienced—or come close to experiencing—stress or risk from a mailing delay affecting a deadline. For 13%, it went further than a close call: a missed deadline, a penalty, or a client issue.

For those 13%, the consequences were real—a missed filing window, a client penalty, or hours spent on damage control instead of client work.
A missed mailing deadline in accounting isn’t just an inconvenience. It can mean IRS penalties, damaged client relationships, and hours spent on damage control. The risk is built into the work—but it doesn’t have to be amplified by a mailing process that makes things harder than they need to be.
The goal isn’t to stop mailing. Tax documents, Certified Mail, client correspondence—physical mail is a fixture of accounting work and, for many filings, it’s required. What can change is the process around it.
Modernizing mailing for accounting firms means printing postage and labels from your desk, scheduling pickups instead of making mailing trips, getting accurate postage every time so you’re not overspending, and keeping a digital record of what went out and when. That last piece matters more than it might seem: when a question comes up two years later about whether something was mailed and when, a sending log answers it immediately.
With Stamps.com, mailing for accounting firms works around your schedule—not the other way around. You can send Certified Mail, print exact postage for any document type, access discounted rates from UPS, USPS, and other carriers, and track every outgoing piece from a single dashboard. During busy season especially, that kind of reliability isn’t a nice-to-have. It’s how you protect your clients and your firm.
I needed the convenience of not having to stand at the post office so I could accomplish my work when I was ready to do it, not when someone else’s hours dictated.
