If you run deliveries on QuickBooks Online and you’ve been shopping for a proof-of-delivery app, you’ve probably noticed something annoying. Almost none of them sync with QB out of the box. The ones that claim to mostly do it through Zapier, which works until it doesn’t, and the QB integration is usually an afterthought rather than a real feature.
Here’s the actual landscape in 2026. What “syncs with QuickBooks” really means, which POD apps deliver it, and what to ask before signing up for one.
What “QB sync” actually means
It’s a spectrum. The cheap version is one-way and shallow. The good version is two-way and deep. Most apps live somewhere in the middle.
One-way, shallow
The POD app reads invoices from QB, lets you mark them delivered, and stops there. Anything that happens after delivery (the signed PDF, the GPS coordinates, the customer’s name on the signature) stays inside the POD app. Your QB invoice has no idea the delivery actually happened. Office staff have to update QB by hand if you want it reflected there.
This is what most POD apps deliver when they say “QuickBooks integration.”
One-way, deeper
Same as above, but the app can also push status changes back into QB (paid, cancelled, refunded). Still no signature image, no proof of delivery PDF, no timestamp. Better than nothing.
Two-way, deep
The POD app reads invoices from QB and writes the signed status, signature image, GPS coordinates, timestamp, and a link to the signed PDF back to the corresponding QB invoice. The accounting record becomes the audit trail. Office staff never touch QB to mark deliveries.
This is what Billet does. It’s also what almost no other POD app does, despite what their marketing pages claim.
The shortlist of POD apps with QB sync
Most well-known POD apps don’t have a real QB integration at all. The honest list:
- Billet. Two-way native, $5 per user per month.
- Detrack. Zapier only, around $25 per user per month.
- Track-POD. Zapier only, around $29 per user per month.
- Onfleet. No native QB, partner-built integrations of varying quality.
Notably absent: Shipday, Samsara, Route4Me, Locate2u. None of them have a real QuickBooks integration.
What to ask before you sign up
Five questions to put to any POD app’s sales team:
- Is the QB sync native or Zapier? Zapier is fine for prototyping. It’s a fragile dependency for production. If the answer is Zapier, the integration will break the first time QB or Zapier updates an API contract.
- Is the sync one-way or two-way? If it’s one-way, plan for the office staff to spend time updating QB by hand.
- What fields actually round-trip? Status only, or also signature image, timestamp, and GPS? The audit trail depends on this.
- Where does the signed PDF live? In the POD app forever, or attached to the QB invoice? The latter is what most accountants and auditors actually want.
- What happens when QB customers, items, or tax rates change? Does the POD app pick up the change automatically, or do you have to re-import? Drift between QB and the POD app is the source of half the support tickets shops generate.
If any of those answers are vague, the integration probably isn’t real.
How Billet’s QB sync works
The flow:
- Connect QuickBooks Online from Billet’s Integrations page. One-click OAuth.
- Customers, items, and tax rates sync over automatically. Changes in QB show up in Billet within a few minutes via webhook.
- Create or import an invoice. Either start it in QB and import to Billet, or start it in Billet and push to QB.
- Driver delivers, captures signature in person on the iPad (or the customer signs remotely via email link). GPS, timestamp, and signature image captured automatically.
- Billet pushes the signed status, signature image, GPS coordinates, and timestamp back to QB. The signed PDF is uploaded as an attachment on the QB invoice.
Office staff never have to update QB by hand. The accountant sees the full audit trail in QB at month-end without lifting a finger.
Common questions
What if I use QuickBooks Desktop instead of QuickBooks Online? The native sync is for QB Online. QB Desktop is supported in the Professional tier via the Windows ODBC connector (separate setup, more steps).
Does it work for invoices, estimates, and sales receipts? Yes for invoices and estimates (estimates can be converted to invoices in Billet and pushed to QB). Sales receipts are supported on the Professional tier.
What happens if QB is down? Billet queues sync events locally and retries automatically when QB’s API comes back. You don’t lose data. The signed PDF is generated and saved regardless of QB status.
Can I disconnect QB later without losing my Billet data? Yes. Disconnecting QB stops the sync but leaves all your Billet records intact. You can reconnect anytime.
