How does Well match Square records to entries in QuickBooks?

Every Square charge is scored against your open QuickBooks sales invoices and existing customer records on customer name, amount, currency, and reference. Above 85% the charge collapses onto the right invoice and Square reconciliation builds the matched journal entry in Well's ledger, the ledger accounts mapped and the matched customer and payment pre-filled, ready for you to post to QuickBooks. Between 55% and 85% the candidate list is queued for review with the alternative customers ranked.

Does Well handle multi-currency records between Square and QuickBooks?

Square carries the original transaction currency on every record and QuickBooks natively ledgers in multiple currencies. Well preserves the original amount, applies your QuickBooks chart-of-accounts conversion rules at posting time, and both the source and converted amounts ride on the document Well forwards to QuickBooks, so the QuickBooks entry you post keeps both sides of the trade.

How does Well prevent duplicates when posting Square records to QuickBooks?

Square sends each event with a stable resource ID that Well tracks against the QuickBooks ledger. Webhook replays (which Square can issue for delivery retries) are recognised by ID and either skipped or used to update the existing QuickBooks entry. Distinct records that look similar are caught by Well before posting, with the candidates surfaced in the review queue when confidence is ambiguous.

Can I customise which Square fields are sent to QuickBooks?

The default mapping covers every Square field your QuickBooks chart of accounts accepts (counterparty, amount, currency, reference, tax). From the integration settings page you can override mappings field-by-field, attach computed values from your connected data (GL code, project tag, tax bucket), or ignore fields QuickBooks does not need. Custom mappings are versioned and apply only to records reconciled after the change, so anything you have already reviewed and posted in QuickBooks is left exactly as it stands.

What happens if a Square record fails to post to QuickBooks?

When a record fails to post to QuickBooks (validation rule, missing field, transient 5xx), Well retries automatically with backoff. Auth failures short-circuit the retry loop and notify the workspace owner; schema rejections are kept on the integration status page with a one-click retry-after-fix action pointing back at the original Square record. Nothing silently drops.

How does Well authenticate with Square and QuickBooks?

Square's MCP server handles authorisation directly; Well receives an access token through Dynamic Client Registration and never sees raw user credentials. For the delivery side, Well forwards the reconciled document to your QuickBooks email-in address once it clears the matching threshold; QuickBooks creates the draft record from it and you confirm and post it. Well holds no write credential to QuickBooks. Tokens are encrypted at rest and in transit under TLS 1.3. Square and QuickBooks together cover multiple regions; Well's storage region is configured per workspace.

Reconcile charges to the sales journal

Every Square charge becomes a sales-journal entry in QuickBooks with VAT split per line, the customer linked to its existing ledger account, and the matched bank deposit annotated on the entry. Nothing posts twice because the Square charge ID is tracked through the QuickBooks entry.

Resolve refund and dispute writebacks

Refunds and chargebacks from Square land as reversing entries in QuickBooks the moment the dispute is opened, with the original charge auto-linked so the audit trail keeps both sides of the trade. The reversal carries the dispute reason so the accounting team does not have to dig through Square to write the note.

Bring multi-currency charges into one ledger

Each Square charge keeps its original transaction currency on the matched document. Well stamps the FX rate at the timestamp of the event and attaches both the source and converted amounts to the document forwarded to QuickBooks, so the draft your team confirms stands up to audit.

Decompose fees from a card payment

Every Square card charge is split inside Well into the gross amount, the processor fee, and the net deposit. The fee context is broken out on the document forwarded to QuickBooks, ready for your team to route it onto the processor-fee account on confirmation.
