A Joiin alternative for QuickBooks Online groups
Updated
SigmaClose combines several QuickBooks Online companies into one P&L, balance sheet and cash flow, for one flat price per group. It does one job: QuickBooks Online consolidation, in US dollars, done carefully.
Why people look for a Joiin alternative
Joiin is a consolidation and reporting tool that works with several accounting systems, including Xero and QuickBooks, and its plans are priced by how many companies you connect (Joiin's pricing). For a small group whose companies are all on QuickBooks Online, the reason to look elsewhere is usually the bill growing with each company you add.
We were in that spot with our own three companies. So we built SigmaClose, moved our month-end onto it, and checked it against the numbers we had before: every account line, every month since April 2026, to the cent.
How SigmaClose is different
- One price for the group. Planned as one flat monthly price for any number of companies and people. Adding a company doesn't change it.
- Built only for QuickBooks Online. It reads each company's monthly reports from QuickBooks and never writes to them. The narrow scope is the point.
- Eliminations in the open. Their own column on every statement, suggested pairs with the reason, and any difference in a balancing account in Equity, flagged by the month-end checks.
- A report pack in your colors. Cover, summary and the three statements in one PDF, with your logo and color read from your website.
- For your AI assistant, too. A read-only MCP server, so Claude and similar assistants can read the statements and explain a line.
- Phone apps coming. iPhone and Android, with an alert when a month-end check fails.
What SigmaClose doesn't do
Being plain about it: SigmaClose works with QuickBooks Online only, in US dollars only. It has no budgets, forecasts or custom report layouts, and no accountant view across several client groups yet. If you need those today, it isn't the right fit yet.

Questions
Is SigmaClose a Joiin alternative?
For groups whose companies are all on QuickBooks Online in US dollars, yes. SigmaClose combines them into one profit and loss, balance sheet and cash flow by month, with intercompany eliminations, a branded report pack and Excel, CSV and PDF exports.
How is SigmaClose priced compared with Joiin?
Joiin's plans are priced by the number of companies; see joiin.co/pricing for current prices. SigmaClose plans one flat monthly price per group for any number of companies and people. Our price isn't set yet, and no one is charged until it is.
Can I check SigmaClose's numbers against Joiin?
Yes. Connect the same companies, add the same elimination pairs and compare a month side by side. We did exactly that for our own three companies: every account line from April 2026 on matched to the cent.
Does SigmaClose work with Xero?
No. SigmaClose works with QuickBooks Online only, for companies that keep their books in US dollars.
