Why Use Xendoo?

Weekly books, published monthly: Transactions are categorized and reconciled every week, so cash flow questions get answered while decisions are still being made.

Visibility included: Insights XP gives every client a live view of trends, key metrics, and reports without paying extra for a dashboard.

Predictable pricing: Plans are published and tiered by monthly expense volume, so owners know what they will pay before they sign.

Room to grow: A business can start on Essential, move to modified accrual on Growth, and add tax, catch up work, or fractional CFO support as needs evolve.

Good to Know

• Tax filing is purchased alongside a bookkeeping plan, so businesses choose the level of tax support they need. Accounting and Tax both in-house for complete visibility into the businesses needs.
• The Essential plan is cash basis. Modified accrual is available on Growth and Scale, and full accrual is available through a custom plan.

Best for: Small businesses on QuickBooks Online or Xero that want weekly bookkeeping, a financial dashboard included, CPA tax filing and advisory support, and transparent pricing from a partner built to scale with them.
