Integrations
Integrations connect EyeOnTask to the tools you already pay for — your accounting package, your payment processor, your SMS provider.

Each card shows a badge — Connected or Disconnected — so the state of every connection is visible at a glance.
What each one does
Section titled “What each one does”| Integration | What it is for |
|---|---|
| QuickBooks Online | Syncs clients and payments both ways with QuickBooks, and invoices one way, out of EyeOnTask. |
| Xero Online | The same arrangement with Xero — clients and payments two-way, invoices one-way. |
| PayPal | Accepts customer payments through PayPal. |
| Stripe | Accepts card payments through Stripe. |
| Zapier | Connects EyeOnTask to other tools without code, so an event here can trigger an action somewhere else. |
| SMS Gateway | Sends your SMS templates through an SMS account you already hold. |
The two accounting integrations
Section titled “The two accounting integrations”QuickBooks and Xero work the same way and answer the same question: your accountant needs the invoices, and nobody wants to type them twice.
Clients sync in both directions. A customer added in either system appears in the other, so the two client lists stay the same list.
Invoices sync one way — out of EyeOnTask and into the accounting package. The work is scheduled, done and billed here, so an invoice raised directly in QuickBooks or Xero cannot come back the other way.
Payments sync in both directions. A payment recorded in either system reaches the other, so a client who pays through your accountant and a client who pays a fieldworker on site both end up settled in both places. A payment can only cross once its invoice has — see what syncs, and which way.
Connect one, not both. Two accounting packages receiving the same invoices is a reconciliation problem rather than a backup.
Payments
Section titled “Payments”PayPal and Stripe both let a customer pay an invoice you have sent rather than arranging a transfer. Which you use is usually decided by what you already have and what your customers expect; connecting both is reasonable if your customer base is split.
A payment taken through either is recorded against the invoice, so the outstanding balance is right without anyone marking it off by hand.
SMS gateway
Section titled “SMS gateway”The gateway is the account that actually sends text messages. EyeOnTask writes them; the gateway delivers them. Until one is connected, the SMS templates exist but nothing goes out — which is what the banner on the SMS template screen is telling you.
Setting one up
Section titled “Setting one up”Each connection is made from its card, and each has its own steps because each is a different company’s account. The individual walkthroughs are:
In every case you are signing in to that service and authorising EyeOnTask, so have the account details to hand before you start — and use the account your business actually trades on, not a personal one set up to test with.
When a sync fails
Section titled “When a sync fails”A connection that has been working can still refuse an individual invoice or client, and the message you get back comes from QuickBooks or Xero rather than from EyeOnTask. QuickBooks and Xero sync errors covers what each one means and what to do about it.
