Keeping Xero should be an explicit requirement
Bookkeeper360, Acuity, Xendoo, and Wiss each describe support for bookkeeping or outsourced accounting in Xero. They form a practical US-facing shortlist if you want a service team while retaining that ledger. They are not interchangeable, and this selection is not a global ranking of Xero advisers. Country, tax, and professional requirements still need to match your business.
Tell each candidate whether you intend to retain the existing Xero organization, its historical records, and its connected apps. A provider's general familiarity with Xero does not establish the work included in a particular package. Ask it to identify the organization it will operate, the data it needs, and any proposed changes before signing.

Compare the four providers
The documented service differences give you a starting point for interviews. Use your own accounting basis, reporting needs, transaction volumes, and tax jurisdiction to narrow the list. If a required capability is unclear, ask for a written answer rather than interpreting a software logo as a complete service commitment.
| Provider | Published Xero fit | Check in the proposal |
|---|---|---|
| Bookkeeper360 | App connects to Xero and QuickBooks | Accounting basis, close cadence and added services |
| Acuity | Xero listed in its bookkeeping software support | Controller review, tax scope and app workflows |
| Xendoo | FAQ states it works in Xero and QBO | The plan's accrual limits and commerce requirements |
| Wiss | Outsourced accounting within Xero described | Internal-team boundary and reporting requirements |

Bookkeeper360 for a service connected to the existing ledger
Bookkeeper360 describes direct Xero and QuickBooks integration and a service offering that can extend beyond bookkeeping. Its pricing page separates onboarding and prior bookkeeping from recurring work. Ask how it will use the existing Xero organization and which historical balances it will review before accepting the starting position.
Request the accounting basis and reporting cadence in writing. Then specify the connected systems that affect the books, such as payroll, payment processors, or inventory records. An app connection can transfer data without resolving every accounting question. Identify who reviews exceptions, who maintains supporting schedules, and which tax or advisory services require another scope.

Acuity for bookkeeping with optional senior accounting support
Acuity's bookkeeping FAQ lists Xero among the systems it works with and describes bookkeeping separately from tax preparation. Its broader offering includes controller services. A business that wants to keep Xero can investigate whether it needs transaction processing alone or additional accounting review.
Ask how the team handles the Xero apps already in use and what it would change. For a service company, that may involve invoicing and project costs. For a retailer, it may involve settlement and inventory schedules. Confirm the exact deliverables and the person who reviews them. If you retain a separate tax preparer, agree how year-end questions and adjustments move between the two teams.

Xendoo for a defined bookkeeping and commerce workflow
Xendoo's FAQ states that it works with Xero and QuickBooks Online. It also describes bookkeeping for sellers using platforms such as Amazon and Shopify, including A2X or sales-report workflows. Ask how the team would reconcile your actual channels and what information it needs when an integration does not provide all the necessary detail.
The same FAQ describes a modified-accrual scope that excludes items such as deferred revenue and prepaid expenses. Confirm the current plan that would apply to your company. A subscription business needing full accrual schedules should resolve that requirement before buying; software compatibility alone does not make every bookkeeping plan suitable for every accounting basis.
Keep sales-channel reconciliation separate from tax filing assumptions. Ask which returns and jurisdictions the proposed tax service covers and what the business must supply to support them.

Wiss for an outsourced accounting assignment in Xero
Wiss's Xero page describes an outsourced service for businesses that want to use Xero without managing the books internally. That makes it a candidate when you want to discuss the accounting work within your existing system rather than accept migration as part of changing providers.
Bring the reports your management team relies on, including any schedules outside Xero. Ask which ones the engagement would maintain and what remains with internal staff. If you have a controller, decide whether the provider prepares the close for that person to review or takes broader responsibility. Request the specific team, review process, and implementation scope for any system changes it recommends.

Check country and professional scope independently of Xero support
A provider can know the software while lacking the local service arrangement your business needs. Identify the legal entity, tax jurisdiction, reporting requirements, and language or time-zone needs. Ask which professionals handle filings and advice, and which matters remain with a local accountant, payroll provider, or legal adviser.
For a group with companies in several countries, agree whether each Xero organization receives local bookkeeping, group reporting adjustments, or both. Name the owner of intercompany reconciliations and any currency-conversion work. Avoid assuming that a multi-currency ledger automatically provides a complete cross-border accounting service.
Retain usable records through the transition
Keep company-controlled administrator access and give the provider named permissions appropriate to its work. Agree how bank feeds, connected apps, document storage, and tax access will be handled. Remove the outgoing team's access only after the agreed handover is complete and the new arrangement can operate.
Identify the last reliable close and collect its reconciliations, supporting schedules, and unresolved questions. Ask the new team to distinguish transferring records from correcting historical errors. Finish the comparison with a first-close calendar, the complete first-year cost, and the reports and schedules your business receives if the engagement later ends.
