A part-time salesperson working 10 to 20 hours a week can run one narrow outbound motion: build a list of one kind of buyer, email or call them, follow up, and hand you booked meetings. They cannot also run your inbox, your CRM clean-up and your events. Pay them hourly or a smaller base plus commission, put the job on one page before they start, and decide up front who answers replies on the days they are not working. Most part-time setups fail on that last point, not on talent.

What 10 to 20 hours a week actually buys

The Bureau of Labor Statistics counts part-time workers as people who usually work fewer than 35 hours a week, so almost any arrangement short of a full week qualifies. What you are really buying is a small block of focused time. Here is how 15 hours a week tends to divide when the job is outbound:

  • 4 hours finding and researching the right people
  • 5 hours writing and sending first emails or making calls
  • 3 hours on follow-ups and replies
  • 2 hours on the meetings themselves
  • 1 hour reporting to you what happened

Those hours are a planning split, not a benchmark, and your own numbers will differ by market. The point is that research and follow-up eat about half the week. A person who gets 15 hours and spends 8 of them in your tools learning where things are has delivered very little in month one. Budget for that. Judge the first month on whether the process exists, and judge the second and third months on meetings booked.

How people pay a part-time rep

There are three common shapes.

  • Hourly. You pay for hours worked. It is the easiest to explain and the easiest to cap, but it pays the same for a week of good work and a week of bad work.
  • Small base plus commission. A modest guaranteed amount for the hours, plus a payout per qualified meeting or per closed deal. The Bureau of Labor Statistics says most wholesale and manufacturing sales representatives are paid a combination of salary and commissions, or salary plus bonuses, so this is the normal shape of the job.
  • Commission only. No guaranteed pay. It carries legal and quality risks of its own, covered in how to hire a salesperson on commission.

For a sense of scale, the Bureau of Labor Statistics' May 2025 data puts the median pay for wholesale and manufacturing sales representatives at $36.76 an hour. That wage figure includes commissions and production bonuses and leaves out employer benefits, and it is an all-industry median for a role that is mostly full time, so treat it as one reference point and not a quote. At that rate, 15 hours a week is about $550 a week before payroll costs. Your actual rate depends on your city, your product and how much of the pay rides on results.

One more point on pay. If you call the person a contractor to avoid payroll, know that the Department of Labor says the label does not decide status. It looks at factors such as the nature and degree of control, the permanence of the relationship and whether the work is an integral part of your business. A part-timer you schedule, train and supervise may well be an employee, so check before you sign. For comparison, here is the full first-year cost of a full-time salesperson.

Where part-time setups fail

Replies land on the days they are off

Say a rep works Monday, Wednesday and Friday. A buyer answers a Monday email on Tuesday morning at 9. If nobody owns that reply, it sits until Wednesday, and a warm reply cools fast. Decide the rule before the first email goes out: either the rep checks the sales inbox for 15 minutes every day they are off, or you answer replies on their off days from a short script they wrote, or replies get answered by whoever is on duty and logged for the rep.

Follow-up falls through the gaps

Follow-up is where a lot of replies come from, and it is also the first thing to slip when the person is only there part of the week. If step two of a sequence is due Thursday and the rep works Wednesday and Friday, it goes out Friday. Write the follow-up schedule around their working days, or keep the sending on a schedule that does not depend on anyone being at a desk.

Context switching eats the hours

A part-timer who also has another job, or who is pulled into your support tickets, spends the first 30 to 45 minutes of every session remembering where things were. Over 15 hours spread across five days, that is a real share of the week. Fewer, longer blocks work better than many short ones. For outbound work, two long days beat five short ones.

Nobody owns the numbers

If the part-timer reports to a founder who is busy, the weekly check-in is the first meeting to be cancelled. Put a fixed 20-minute slot on both calendars and keep it.

A filled-in one-page scope

Write this before you post the job. Say the business is a made-up managed IT company in Columbus, Ohio, selling monthly IT support to law firms.

  • Role: Part-time outbound sales rep, 15 hours a week, Tuesday and Thursday, 7 hours each, plus 1 hour reporting on Friday.
  • Who we sell to: Independent law firms with 5 to 25 staff within 50 miles of Columbus.
  • Your outcome: Qualified meetings. A qualified meeting is a 20-minute call with the managing partner or office manager, who confirms they have no IT contract today or pay someone more than $1,000 a month for one.
  • Target: 6 qualified meetings a month by month three. Month one is for building the list and testing two emails.
  • Tools we provide: A shared sales inbox, the CRM, a calendar link, an approved email template and a list of 300 firms to start.
  • Replies: The rep checks the sales inbox for 15 minutes on Monday, Wednesday and Friday mornings. Anything asking about price goes to the owner the same day.
  • Pay: $22 an hour plus $75 per qualified meeting that takes place. Paid every two weeks. (Placeholder numbers: replace with your own.)
  • Check-in: Friday, 20 minutes, covering numbers, the three best and three worst replies, and one change to try next week.
  • Review point: Day 45. If fewer than 3 qualified meetings have happened and the process is not in place, we stop or change the scope.
  • Not included: Support tickets, proposals, technical work, social media.

Notice what the page does. It names one buyer, defines the one result, and says who does what on the off days. That is most of the job of managing a part-time person.

The alternatives

A part-timer is one of several ways to get outbound done without a full-time hire. Commission-only costs less up front and is harder to hire well, which is why it gets its own article. A founder who keeps the selling in-house can read why founder-led sales does not scale by hiring for when to hold off on a rep entirely.

The other option is an AI salesperson: software that finds the buyers, writes to them, follows up and books meetings without needing a schedule. It does not take a day off, and the replies that land on a Tuesday get answered on Tuesday. It does not run the sales meeting, negotiate or close, so you still show up for the meeting itself. If your real constraint is hours, not judgment, it is worth weighing against a person at 15 hours a week.

Rocketship is built as that kind of salesperson: it does the research, emails from your own Gmail, follows up and books meetings every day of the week. Plans start at $12 a month on the pricing page, and a 7-day trial, card required, lets you test it against your own list.
