“Excelled People For Excellent Services”

Startup accounting services, done for you.

Excello provides startup accounting services: outsourced bookkeeping, fractional CFO support, payroll and tax, done by accountants inside the QuickBooks, Xero or Odoo you already use.

Software pulls in and matches your transactions every day. Accountants review them every week, or every business day on the higher plans, and close the month within five business days.

For teams who want the finance work off their desk

Who it is for

It's for founders and operators who spend late nights categorizing receipts, working out payroll by hand or chasing missing vendor invoices.

It's for teams whose last bookkeeper took weeks to close the month, which left leadership making commitments on bank balances nobody had checked.

And it's for growing companies that need senior finance guidance but can't yet justify a full-time finance director.

  • Founders who want the finance work done, not another tool to manage
  • Companies whose monthly close drags on and produces reports nobody trusts
  • Growing businesses that need payroll and tax handled without hiring
  • Leadership teams that want cash planning and scenario models from finance professionals

Frequently asked questions

What are startup accounting services?

Startup accounting services are the finance work a young company needs but rarely has staff for. That means bookkeeping, the month-end close, payroll, tax work and financial planning, done by an outsourced provider inside the company's own accounting software, with closed books and reports every month.

Can Excello's services run inside my current accounting software?

Yes. Excello works inside your existing QuickBooks, Xero or Odoo file. You keep the subscription, the admin login and the full transaction history, and there is nothing to migrate.

Who actually does the work?

Accountants do. Software pulls in and matches transactions every day, then accountants review and categorize them weekly or every business day, reconcile each balance and sign off the month-end close within five business days.

Can I take just one service, or is it a bundle?

Any service can be taken on its own. Outsourced bookkeeping, fractional CFO support, payroll and tax are each available separately, and you can add another service whenever the business needs it.

Do you replace my accountant, or work with them?

Either. Excello can run your whole accounting function, or work alongside your in-house team and your outside tax adviser, keeping the monthly books current and handing your CPA organized workpapers at year-end.

What happens to my books if I leave?

They stay yours. The work happens inside your own accounting software, so if you move to an in-house hire or another provider, your ledger is already up to date and there is nothing to export.

How are Excello's services priced?

Each service is quoted before any work starts. Outsourced bookkeeping starts at $150 a month, and every quote depends on your transaction volume, the number of accounts and which services you add.
