Contractor Pay Run Automation
Automatically pull approved contractor hours, generate bills in your accounting system, execute batch payments across currencies, and send confirmations. One click replaces a full day of manual processing.
A Full Day Gone, Every Fortnight
You've got 25 contractors. Some are local, some are overseas, and every two weeks somebody on your team sits down to process their payments. They pull hours from a spreadsheet, cross check rates, create individual bills in Xero or QuickBooks, then execute bank transfers one at a time. After that, they send confirmation emails. For 25 people, that's a full day of work.
And it scales linearly. Thirty contractors? Longer day. Fifty? You're hiring someone just to run payroll for people who aren't even on payroll.
Teams spend up to 25 hours per week on manual data entry across finance operations. Contractor pay runs are one of the worst offenders because every payment touches multiple systems: your time tracker, your accounting platform, your bank, and your email. None of them talk to each other unless you make them.
Then there's the compliance risk. Misclassification penalties, missed 1099 thresholds, and tax reporting errors don't announce themselves until an audit lands on your desk. The IRS charges between $60 and $310 per form for 1099 failures. When you're managing dozens of contractors, those numbers add up fast.
How It Works
Here's what the automation does, end to end. Your only job is approving the hours before it runs.
1. Scheduled trigger fires on pay day
Every fortnight (or whatever cycle you run), an n8n or Make scenario kicks off automatically. No one needs to remember it's pay day. The workflow pulls the current pay period dates and begins processing.
2. Pull approved hours and rates
The automation connects to your time tracking source, whether that's Airtable, Harvest, or a Google Sheet. It filters for entries marked as approved within the current pay period. Unapproved entries are skipped and flagged for review.
3. Calculate pay amounts per contractor
For each contractor, the system multiplies approved hours by their agreed rate. Adjustments, bonuses, or deductions you've recorded against that contractor are applied automatically. The output is a clean list: contractor name, amount owed, currency, and payment method.
4. Create bills in your accounting system
Individual bills are generated in Xero or QuickBooks for each contractor. Each bill references the pay period, project codes, and hours. Your books stay accurate without anyone touching the accounting software.
5. Generate and send batch payment file
The workflow builds a CSV or API payload formatted for your payment provider. Wise BatchTransfer can process up to 1,000 payments from a single file. For domestic only payments, your bank's batch upload works too.
6. Execute payments and confirm
Payments are triggered through the Wise API or PayPal Mass Payments. Each contractor receives a personalised confirmation email with the amount, pay period, and expected arrival date. No one on your team writes a single email.
7. Update records and close the loop
Every contractor record in your tracking system gets updated with the payment date, amount, reference number, and status. Your next pay run starts with a clean slate.
Why Spreadsheets and Manual Batch Uploads Fall Short
Most businesses hit a point where they try to speed things up with a spreadsheet template. You build a master sheet with contractor names, rates, and bank details. You paste in the hours, run some formulas, export a CSV, and upload it to Wise or your bank. That's better than doing everything individually, but it's still fragile.
Someone changes their bank details and forgets to tell you. The spreadsheet doesn't know. A contractor's rate went up last month but the formula still uses the old one. Nobody catches it until the contractor emails you, annoyed. Or worse: you overpay someone and spend a week chasing a refund across international borders.
It's the 15th. You open the spreadsheet, paste in hours for 28 contractors, spot a rate discrepancy for someone in the Philippines, spend 40 minutes tracking down the correct figure, then upload the batch file. Wise rejects three rows because the bank details format changed. You fix them manually, resubmit, and start writing confirmation emails. It's 4pm.
The spreadsheet approach also can't flag compliance issues. It won't tell you that a US based contractor just crossed the $600 cumulative payment threshold and needs a W9 on file. It won't catch unusual hours that suggest a timesheet error. It just calculates what you give it.
Multi Currency Payments Without the Guesswork
If you're paying contractors in more than one country, exchange rates become a silent cost centre. Traditional bank transfers mark up the exchange rate by 1% to 3%. On a $5,000 payment to a developer in Poland, that's $50 to $150 lost every single transfer.
Batch payment providers like Wise use the mid market exchange rate with transparent fees, typically 0.3% to 1.5% depending on the currency corridor. The automation locks in the rate at the moment of transfer, so there's no gap between what you approved and what gets sent. Your accounting system records the exact amount in both currencies.
For a business sending $30,000 per month to international contractors, switching from bank transfers to automated batch payments through Wise saves roughly $3,600 to $10,800 per year on exchange rate margins alone. That's before you count the time savings.
The Business Impact
Let's do the maths for a 15 person agency running 25 contractors on fortnightly pay cycles.
Your office manager currently spends about seven hours per pay run on contractor payments. That's pulling hours, creating bills, executing transfers, sending confirmations, and fixing errors. At $45 per hour, each pay run costs $315 in labour. Over 26 fortnightly cycles per year, that's $8,190 just in processing time.
With the automation, the same pay run takes about 15 minutes of human effort: reviewing the approved hours list and clicking to confirm the batch. Call it $11 per cycle. Annual cost: $286. That's a saving of $7,904 in labour alone.
Add the exchange rate savings for international payments. If half your contractor spend ($15,000 per month) goes overseas, moving from bank transfers to Wise batch payments saves 1% to 3% on conversion. Conservative estimate: $1,800 per year. Total first year saving: roughly $9,700.

- Contractor payment confirmations sent instantly, no manual emails
- Exchange rate savings of 1% to 3% on every international transfer
- Compliance tracking flags contractors approaching 1099 thresholds
- Complete audit trail for every payment, linked to approved timesheets
Frequently Asked Questions
We only have 10 contractors. Is this worth it?
At roughly 20 minutes per contractor for the full cycle (hours review, bill creation, payment, confirmation), that's still over three hours per pay run. If you run fortnightly cycles, you're spending 80+ hours a year on a task that could take 15 minutes. The automation pays for itself within the first quarter.
Our contractors submit invoices in different formats. Can the automation handle that?
Yes. You can either standardise intake by giving contractors an Airtable or Google Form to submit their hours directly, or use OCR and AI to extract data from PDF and emailed invoices. Most businesses find the form approach simpler and more reliable for everyone involved.
Does this replace our approval process?
No. The automation only processes hours that have already been approved. Your project managers or team leads still review and approve timesheets in whatever tool you use. The pay run triggers after approval, not instead of it.
What accounting systems does this integrate with?
The workflow connects to Xero, QuickBooks Online, and MYOB for bill creation. For payments, it works with Wise BatchTransfer, PayPal Mass Payments, and most banks that accept batch upload files. Your time tracking can be Airtable, Harvest, Toggl, Google Sheets, or any system with an API.
How does it handle contractors who change their bank details?
Contractor bank details are stored in your master tracking system (such as Airtable). When a contractor updates their details, the next pay run automatically uses the new information. The workflow also validates bank details against the payment provider's requirements before submitting, so format errors get caught before the batch is sent.
Is this compliant with Australian tax requirements?
The automation creates a full audit trail linking approved hours to bills and payments. For Australian businesses, it tracks cumulative payments to each contractor for TPAR reporting. For US based contractors, it monitors the $600 threshold for 1099 obligations. You'll want your accountant to review the setup once, but ongoing compliance tracking is handled automatically.
How long does setup take?
Most contractor pay run automations are fully operational within two to three weeks. That includes connecting your time tracker, accounting system, and payment provider, plus building the notification templates.
