Why this is hard
The data always moves.
The meaning doesn't.
Every accounting platform models the same concepts slightly differently. Classes, locations, items, subaccounts, terms, tax codes, and payment linkages all have platform-specific behavior, and the automated migration paths handle the easy 80% while quietly flattening the rest. Historical reports stop tying out. Subaccounts collapse. Inactive items arrive active. Payments detach from the invoices they applied to. Opening balances land as a single lump journal entry with no traceability back to the source.
None of that shows up on migration day. It shows up at the first period close, or worse, at the first audit — at which point the source system may already be decommissioned. The work isn't moving records. It's preserving the relationships between them, and proving afterward that they survived.
Migration services
Four paths we
run regularly.
QuickBooks Desktop to QuickBooks Online
The Intuit-supplied conversion moves the bulk of the file, but it has documented limits — list size caps, payroll history, inventory valuation method, and class or job structures that don't map cleanly. We scope those limits against your actual file before the conversion runs, handle the pieces the automated path won't carry, and reconcile the QBO trial balance back to the Desktop trial balance afterward.
Discuss a QBD migrationQuickBooks Online to QuickBooks Online
Company splits, entity restructuring, consolidating multiple companies into one, or rebuilding a file whose chart of accounts has become unusable. QBO offers no native company-to-company transfer with history, so this is API-driven work: chart of accounts mapping, list migration, transaction replay in dependency order, and a reconciliation pass that proves the destination matches the source.
Discuss a QBO-to-QBO moveXero and QuickBooks Online — Either Direction
Cross-platform moves are where mapping decisions matter most, and they run both ways. Xero's tracking categories, contact model, bank rules, and account types have no one-to-one QBO equivalent — and QBO classes, locations, and separate customer and vendor lists have no clean Xero equivalent either. We agree the mapping with you in writing before anything is written, then migrate lists, balances, and transaction history against it. The decisions are yours and documented, not implied by an import tool.
Discuss a Xero ⇄ QBO migrationPlatforms we migrate
If both ends have a documented API,
we can move it.
The constraint isn't the brand name on the software — it's API access. If the source system exposes a documented read API and the destination exposes a documented write API, the migration is engineering work we can scope. Where a platform's API is read-only, the move is one-directional. Where there's no API at all, it becomes CSV export and mapping work, which is slower and priced differently. Below is where the platforms we're asked about most actually stand.
| Platform | → To QBO | ← From QBO | Integration method |

| QuickBooks Desktop | Full | Limited | qbXML via SDK or Web Connector — no REST API |
| Xero | Full | Full | REST, OAuth 2.0 |

QuickBooks Desktop
Desktop has no REST API. Everything moves through qbXML, using either the QuickBooks SDK on the same machine as the company file or the Web Connector as a bridge for anything hosted remotely. That's a different engineering shape than a cloud-to-cloud move — it needs a Windows environment, a scheduled sync rather than a live connection, and version handling across SDK and Web Connector releases. The Intuit-supplied conversion covers the bulk of a standard file; we handle what it leaves behind and reconcile the result. Moving the other direction, QBO back to Desktop, is technically possible but lossy enough that we scope it case by case rather than treating it as a standard offering.
Xero
The cleanest cross-platform pair we work with — both sides expose full REST read and write over OAuth 2.0, so the engineering effort goes into mapping rather than extraction. The decisions that matter are structural: Xero tracking categories against QBO classes and locations, Xero's single unified contact list against QBO's separate customer and vendor lists, and account type taxonomies that don't line up one to one. We settle all of it in writing before the first write, in either direction.
Sage Business Cloud Accounting
Sage's v3.1 REST API covers contacts, sales and purchase invoices, ledger accounts, journals, tax rates, and bank accounts — everything a migration needs on both ends. The operational catch is token handling: access tokens expire in five minutes and refresh tokens rotate on every single use, so a migration run has to manage credentials carefully or it dies mid-job. Sage also caps requests per company per day, which means a large historical migration gets paced across multiple sessions rather than run in one pass. Note that Sage Intacct, Sage 50, and Sage X3 are entirely different products with different integration models — this covers Business Cloud Accounting only.
Zoho Books
Full REST v3 coverage with OAuth 2.0 in both directions, and the object model maps to QBO more directly than most. Two practical constraints shape the schedule: a per-minute request ceiling per organization, and a daily request cap that varies by the customer's Zoho plan. Zoho also routes by region, so an EU-hosted organization has to be addressed on its own regional endpoint — pointing at the wrong one produces authentication errors that look like credential problems but aren't.
FreshBooks
Full read and write over OAuth 2.0 covering clients, invoices, expenses, payments, and bill payments. FreshBooks is built around service businesses, so the mapping questions are different from a product-based migration: time entries, retainers, and project-based billing have no direct QBO equivalent and need an explicit decision about whether they land as invoices, journal entries, or don't come across at all. That's a conversation we have before the migration, not a discovery you make afterward.
Wave
Wave is asymmetric, and we'd rather say so up front than discover it mid-project. As a destination it works well — the API creates accounts, customers, products, sales taxes, invoices, and payments, plus bulk transaction creation. As a source it's constrained: the API exposes the chart of accounts, customers, vendors, products, taxes, invoices, and estimates, but there is no query that returns general ledger transactions, and account balances are only available as of the current date. That means a Wave-to-QBO migration moves your lists, invoices, and payment records through the API, and the ledger history has to come across via export files and a mapping pass. Vendors are another gap — readable out of Wave, but not creatable in it.
QuickBooks Online
QBO offers no native company-to-company transfer that carries history, which surprises people every time. Entity splits, consolidations, and rebuilds of a file whose chart of accounts has become unworkable are all API-driven jobs: map the chart of accounts, migrate the lists, replay transactions in dependency order, then reconcile. Worth knowing that Intuit now meters read operations under its App Partner Program while writes remain free — so any migration with QBO as the source carries a data-retrieval cost that a QBD-to-QBO job does not.
Don't see your platform? This list is where we get asked most often, not the limit of what we'll take on. NetSuite, MYOB, FreeAgent, Odoo, Dynamics 365 Business Central, and most other systems with published read and write APIs are all workable. Tell us the pair and we'll tell you honestly what will carry, what needs a mapping decision, and what won't come across at all.
Custom QBO integrations
When the connector
doesn't exist yet.
Ten years of QuickBooks Online integration work, direct against the Intuit API. If you have a system that needs to talk to QBO and no off-the-shelf connector does what you need, that's the work. Typical engagements include pushing orders, invoices, or receipts from a platform QBO doesn't natively support; pulling QBO data into a warehouse, BI tool, or internal dashboard; building a sync layer between QBO and an ERP, CRM, POS, or billing system; and replacing a brittle connector that keeps posting duplicates.
How we work
Scope first.
Then write.
Why us
We built the tools that
check the work.
Most migration providers hand you a converted file and an invoice. We hand you the file plus the evidence. Our own forensic products — TheReconciliator, MigrationClarity, and Sealed Ledger — exist specifically because we kept needing to prove that migrated data was intact. Those tools run as part of every migration engagement, and the findings report goes to you whether it's clean or not.
Forty years of moving structured business data, ten of it inside the QuickBooks ecosystem. You talk to the engineer doing the work, not a project coordinator relaying messages.
