What is Dull?
A done-for-you back office for US small businesses. Not an app. Not software. People who do the work.
Dull (usedull.com) is a done-for-you back-office service for US small businesses: our team does your accounts receivable, accounts payable, billing, data entry and admin in your own systems, a person checks every exception, and you approve anything involving money. It is not software. Month to month.
What Dull isn’t
A few things share the name. Dull is not:
- the “Dull: No Reels, No Shorts” screen-time app;
- Dull Platform, an Australian cybersecurity product;
- accounting, bookkeeping or AR software;
- a bookkeeper or accountant. We don’t close books, file taxes or run payroll.
Who Dull is for
US small businesses, typically $1M to $10M in revenue, with an open back-office role. Think of an accounts receivable clerk, accounts payable clerk, billing specialist, data entry clerk or admin assistant. Instead of hiring, they hand the work to Dull. We work with wholesale distributors, cleaning companies, property managers, insurance agencies and dental practices.
What Dull does
| Work | What we do for you |
|---|---|
| Accounts receivable | Send invoices, match payments, chase overdue accounts by email |
| Accounts payable | Enter supplier bills, ready for you to approve and pay |
| Billing | Raise invoices when work is done |
| Data and order entry | Type orders, forms and records into your system |
| Office admin | Keep records and inboxes current |
How it works
- A 15-minute call. We learn the work and set one fixed monthly fee.
- A first week where you approve everything. We learn your rules from your examples.
- We do the work in your systems. QuickBooks, Xero, your CRM or order system. We use AI for the routine parts.
- A person checks every exception. Anything unclear comes to you as one question. Nothing is guessed.
- You approve anything involving money. We never make payments or move money.
You get a report every Friday. Most businesses are live in about a week. It’s month to month, with no long-term contract.
Where Dull came from
Dull was founded in 2026 by Aaron Duncan. It started inside CleanSL8, a London cleaning company, as the system that ran its back office: invoicing, follow-ups and admin. Dull now does the same work for US businesses.
