Company Overview

Our client is a newsletter growth agency. It runs paid Meta ads for newsletter and media brands, large personal brands and founders, and turns readers into revenue. Fees partly move with ad spend and contract terms. The founder launched it in early 2024, and it has grown from 0 to 30+ people in two years. The founder writes tactical posts and hosts a podcast. The team works remotely, and you'd talk with the founder and your manager on calls and in the finance channel on Slack.

Your Role

You're the person who keeps billing and collections running. You send client invoices, follow up on late payments and keep the books current in QuickBooks Online, working fully remote on US Eastern hours as a full-time contractor, reporting to the Operations Manager. The work runs on a set daily routine: the morning Mercury and Stripe check, the 4-week invoice cycle, reminders every 3 working days and a dated note on every action. Your manager is there for questions, and an outside accountant or CPA reviews the books. The hardest balance is speed against accuracy: invoices go out on time, and the variable fees in them are calculated and checked before a client sees them. Get that right and cash arrives on schedule and the founder can trust the numbers.

What You'll Own

- Run Stripe invoicing every 4 weeks, in advance, so each client gets a correct bill on time.

- Work out variable fees from the contract and the ad spend report so every amount is right before it goes out.

- Chase late payments every 3 working days and escalate quiet clients so cash comes in sooner.

- Apply each incoming payment to the right invoice and keep the AR aging report current so the team sees who owes what.

- Keep the QuickBooks Online books current, reconcile the bank and credit card accounts, and support the monthly close so the outside accountant or CPA gets organized files.





- Set up new clients in Stripe, prepare final bills for leavers and support DocuSign contract admin so billing starts and ends cleanly.

- Write down finance steps and maintain the trackers so the team can rely on them.

A Week in the Role

- You open Mercury and Stripe early and spot a failed charge and a renewal coming up. You post both in the start of day update on Slack, so the team knows what needs chasing.

- A client is 3 working days past your last reminder. You send the next one from the shared AR mailbox, in the same thread, and add a dated note to the billing sheet. If the client goes quiet, you escalate.

- A client on a variable fee comes due. You read the contract, pull the ad spend report, work out the fee and check it before sending. The invoice goes out right the first time.

- A payment arrives that doesn't match its invoice. You trace it through the invoice, the payment and the bank line, then post what you found in the finance channel.

- A new client signs. You create the payment link and subscription in Stripe and write down their billing terms, so the first invoice and every one after it use the same facts.

- At month end you reconcile the bank and credit card accounts and prepare the files for the accountant or CPA. You write down any step you had to figure out along the way.

You Bring

- Two or more years in billing, accounts receivable, collections or bookkeeping. Roles where invoicing or payment follow-up was a regular part of your job count,



including assistant, operations and admin roles.

- Experience sending recurring client invoices and following up on late payments until they're paid.

- QuickBooks or a similar accounting tool, plus Excel or Google Sheets, including a billing tracker you kept current.

- Care with numbers: you check every amount before it goes out.

- Clear written and spoken English for client emails, daily updates and calls with the founder and your manager.

- Full time on fixed US Eastern hours, covering at least 9 AM to 1 PM, with this as your only job.

Interview Process

1. First call: 30 minutes with us at atomic HR on what you have built, working terms and what you want next.
2. First interview: a conversation with the Operations Manager, who would be your manager, on how you've handled invoicing and payment follow-up, and how the day-to-day of the seat would go.
3. Short practical test: a task drawn from the seat's own work, done on your own time. It checks that the amounts come out right and that you show how you got to them. We confirm the format and rough time before you start.
4. Call with the founder: a conversation on how you would work together on cash collection and the numbers, and on any questions you have about the company.
