When you bill clients in COLO and keep the books in QuickBooks Online, the days you actually want to be talking to clients tend to be the same days you are re-typing yesterday's invoices into QuickBooks. The Connect COLO with QuickBooks integration makes that re-typing the work the software does, not you.
TL;DR
COLO's QuickBooks integration posts every paid COLO invoice to QuickBooks Online as recorded income against the matching customer, creating that customer on first invoice and flowing payment dates and amounts back to COLO. Drafts, proposals and unsent invoices stay in COLO; QuickBooks payroll, bills and supplier records stay in QuickBooks. Sync is forward-only.
How it works
- Connect — open Settings → Integrations in COLO, click Connect QuickBooks, and authorise the OAuth handshake. Takes about a minute.
- Sync — every paid invoice in COLO posts to QuickBooks as recorded income against the matching customer. New customers are created on the QuickBooks side the first time you invoice them.
- Work — issue invoices in COLO; reconcile in QuickBooks. The two ledgers track each other automatically, so the year-end view is one report instead of a Sunday afternoon of CSV exports.
What syncs
- Paid invoices issued in COLO push to QuickBooks as recorded income.
- Customer records created in COLO map to QuickBooks customers on first invoice — full address and currency carried across.
- Payment dates and amounts flow back to COLO so the project ledger matches the books.
What doesn't sync
- Drafts, proposals, and unsent invoices stay in COLO until they are sent — QuickBooks should not see speculative revenue.
- QuickBooks payroll, bills, and supplier records do not flow back into COLO — those stay where they belong, in your accounting system.
A typical workflow
Monday morning, an enquiry from last week's referral lands in COLO. You pull a proposal template, send it with the deposit invoice attached, and the client signs and pays by Wednesday. The moment the payment confirms, the integration posts the invoice to QuickBooks as income — same line item, same customer, same currency. The bookkeeper opens QuickBooks Thursday to reconcile, sees the new entry already matched against the bank deposit, and approves it in one click. There is no CSV export, no manual customer creation, no untangling which payment matched which invoice. The client work stays in COLO; the financial reporting stays in QuickBooks; the two read from the same numbers all the way to year-end.
By month-close, the only manual step left is reviewing the P&L — every revenue line is already in QuickBooks with the matching customer and date stamp, and every paid invoice in COLO links back to the QuickBooks transaction so you can audit either side from the other in two clicks.
Setup in 60 seconds
- Go to Settings → Integrations in your COLO workspace
- Click 'Connect QuickBooks' and authorise the OAuth scopes
- Pick your default income account and you are done — the next paid invoice posts to QuickBooks automatically
FAQ
Q: Can I disconnect later?
Yes. The integration is one toggle in Settings → Integrations. Disconnecting stops new sync events; nothing already synced is removed from QuickBooks. You can reconnect at any time.
Q: Does it support 2-way sync?
Partially. Invoice and payment state flows COLO → QuickBooks; payment confirmation flows back.
Customer and product catalog edits in QuickBooks are not pushed into COLO — keeping COLO as the single source of truth for client-facing work avoids loops where two systems fight over the same record.
Q: Is my data secure?
Yes. Authorisation uses the QuickBooks OAuth2 flow — COLO stores a refresh token, never your QuickBooks password. Tokens are encrypted at rest and revocable from either side at any time.
Q: Does it cost extra?
No. The integration is included in every paid COLO plan at no extra fee. You only need a paid QuickBooks Online subscription on the other side.
Q: What about my historical data?
The integration syncs going forward only. Invoices issued before you connected will not back-fill into QuickBooks — that keeps the books honest and avoids double-counting against entries you may have already imported manually.
