"Call me in May." Nearly every accounting firm owner says it between January and April, and they mean it. Vendors who sell successfully to firms take that sentence as a calendar, not a brush-off. Timing decides more than the pitch does. A good script sent in March goes unread, and an average one sent in the second week of May gets a reply.
This guide is for vendors selling to accounting firms: software, services, staffing, marketing. It gives the dates when owners will actually answer, a call script for a firm owner, an email for an operations partner, a voicemail, a May-to-October follow-up calendar, and a short note for March. It is separate from marketing a firm's own services; for that side, see getting clients for an accounting firm.
When accountants answer, and when they do not
US accounting firms are slammed from January through the individual filing deadline in mid-April. Partnership and S-corporation returns on extension are due September 15, and individual and C-corporation returns on extension are due October 15, so those weeks bring a second, smaller squeeze. That leaves two real windows for a vendor: roughly May through August, and from the day after the October extension deadline until the first week of December. Most firms also run year-end planning in December and prepare for W-2 and 1099 deadlines in January.
Treat the calendar in this article as a starting point, then ask each firm. Some specialize in payroll, bookkeeping, or businesses with year-end close in other months, and their busy seasons differ.
The call script for a firm owner
Elena sells a tool that lets accounting firms request and collect client documents. Late documents are the thing every firm complains about. She calls managing partners and firm owners in the second week of May.
Hi Gordon, it's Elena Marsh. I know it's the week after the deadline, so I'll keep this short. I help firms collect client documents without chasing by email. You said to call in May, so here I am. How many clients did your team chase for documents this year?
The "you said to call in May" line only works if it's true, so use it only for firms you spoke to or emailed earlier. For a first-ever call, drop it and say: "I know this is the first quiet week for most firms."
Then do the arithmetic with him. If he says 150 clients, ask: "About how many reminders does each one take, and how long does each reminder take?" At two reminders and five minutes each, 150 x 2 x 5 = 1,500 minutes, which is 25 hours of staff time a season. Let him say the number. Then: "I'd like to run a pilot this summer with five of your clients, so you see it work before next January. Could I send you a one-page outline?"
The email for an operations partner
Many firms have an operations partner or practice administrator who does the real evaluating. The email should be short, specific, and calm.
Subject: A five-client summer pilot for document collection
Hi Priya, Gordon suggested I write to you. At two reminders of five minutes each, chasing documents from 150 clients costs about 25 hours of staff time a season. I'd like to run a pilot with five of your clients between July and August, so your team sees it work before January. No cost for the pilot. Could we take 15 minutes next week to decide whether it makes sense? Elena Marsh, 19 Cedar Ln, Madison WI. Reply "stop" and I won't write again.
Include your address and an opt-out line; CAN-SPAM requires both. Send it on a weekday morning, and test the timing against your own replies instead of taking anyone's word for it, including mine. The longer family of templates for this buyer is in cold email templates for accountants.
The voicemail
Gordon, Elena Marsh, 555-0181. I said I'd call in May. I help firms collect client documents without chasing by email, and I'd like to run a five-client pilot this summer. I'll send you a one-pager today and try you again next Tuesday.
The May to October follow-up calendar
| When | What you do |
|---|---|
| May 1 to 15 | First call and email to owners and operations partners |
| May 16 to 31 | Second call or voicemail to anyone who did not answer |
| June | Send the one-page pilot outline to anyone who engaged; agree on five clients |
| July and August | Run pilots, check in every two weeks; one email a month to everyone else |
| September 1 to October 15 | Support pilots only; no new outreach during the extension deadlines |
| October 16 to November 30 | Ask for a decision, since onboarding clients takes about six weeks and January is the deadline |
| December | A short year-end note, no ask |
The March reminder
In early March, send one line to firms you have already spoken with: "Gordon, I know it's the busiest month. No reply needed. I'll call again in the second week of May." It costs nothing, it proves you listen, and it keeps your name in front of someone who then does not feel chased. Do not send it to firms you have never spoken to; a cold message in March is the one unforgivable message.
Log outcomes by date, not just by status
For each firm, record the date of the last contact, what they said about timing ("May," "after the extension deadline"), their tools and renewal dates, and the next action date. A firm that said "after October 15" goes on a calendar entry for October 16, and you call that day. Seasonal buyers are a long game; the arithmetic of sale cycles for them is in average sales cycle length, and a related seasonal-buyer reply is in how to follow up with a lead who said not now. For sending times in general, see the best day and time to send a cold email.

Building the list of firms, sending the emails, and following up on your calendar are what Rocketship does on its own: it finds the buyers, emails them from your own Gmail, follows up, and books the meeting. Plans that get you customers start at $24.99 a month (Launch), and every monthly plan starts with a 7-day free trial, card required. See the AI workers. Answering your existing number is included; a dedicated line is $5 a month.
