Xero Accounts Payable: A Complete Guide to Managing Bills

Accounts payable (AP) is the money your business owes to suppliers. For any small business, managing accounts payable well means paying supplier bills on time without hurting cash flow, catching invoice errors before they become problems, and keeping accurate records for your accountant and HMRC. Xero’s accounts payable features handle all of this.

This guide covers the complete Xero accounts payable process: entering bills, automation, approval workflows, batch payments, and the reports you need to stay in control.

How Accounts Payable Works in Xero

The basic accounts payable process in Xero follows this workflow:

  1. Receive a supplier invoice – by email, post, or from a supplier portal
  2. Enter the bill in Xero – manually or automatically via Hubdoc
  3. Approve the bill – move it from Draft to Awaiting Payment
  4. Schedule payment – schedule payments based on due date and cash flow
  5. Pay the bill – via bank transfer, batch payment, or direct debit
  6. Reconcile the payment – match the bank transaction to the bill during reconciliation

Each step is tracked in your Xero account with a full audit trail. Your accountant can see the complete accounts payable history for any supplier at any time.

Entering Bills in Xero

To enter a supplier invoice as a bill in Xero:

  1. Go to Business > Bills to pay and click New Bill
  2. Select the supplier from your contacts
  3. Enter the invoice date, due date, and the supplier’s invoice reference number
  4. Add line items with account codes and tax rates
  5. Attach a copy of the supplier invoice (PDF or image)
  6. Click Approve

The approved bill appears in your accounts payable immediately. Xero tracks the due date and shows the bill in your Aged Payables report, so you always know what’s outstanding.

Automating Accounts Payable with AP Automation Software

Manual invoice processing is slow and prone to manual errors and data entry mistakes. Xero integrates with AP automation software that dramatically speeds up the accounts payable process:

Hubdoc (included free with Xero)

Email or upload supplier invoices to Hubdoc. It automatically extracts the key data – supplier name, amount, date, invoice number – and creates a draft bill in your Xero account. You review and approve. This automates the most tedious part of accounts payable: data entry.

Hubdoc can automate 60-70% of your invoice processing. For a business handling 50+ supplier invoices per month, that saves hours of manual work every week.

Dext (formerly Receipt Bank)

More advanced AP automation with higher accuracy for complex invoices. Dext handles multi-line invoices, foreign currency bills, and credit notes. It’s the best accounts payable software add-on for businesses processing high volumes.

Lightyear

Specialises in accounts payable automation with three-way matching: the AP system checks the supplier invoice against your purchase order and delivery note before approving payment. This catches discrepancies before you pay.

ApprovalMax

Adds multi-level approval workflows to your Xero accounts payable. Set rules based on invoice amount, supplier category, or department. A £100 stationery invoice auto-approves; a £10,000 equipment bill requires director sign-off.

Accounts Payable Approval Workflows

For businesses that need spending controls, Xero supports bill approval workflows. Staff create bills in Draft status; an authorised approver reviews and approves before the bill can be paid. This prevents unauthorised purchases and catches errors.

For more sophisticated approval workflows, ApprovalMax integrates with Xero to add granular control. You can set up approval chains based on:

  • Amount thresholds – bills under £500 auto-approve, £500-£5,000 need manager approval, over £5,000 need director approval
  • Supplier category – new suppliers always need approval; established suppliers auto-approve within limits
  • Department budgets – approvals check against remaining budget before allowing payment

Approval workflows are essential for businesses with multiple people entering invoices. They create an audit trail showing who approved each payment and when.

Paying Bills in Xero

Individual payments

For one-off payments, pay through your bank’s online portal and then match the payment to the bill during bank reconciliation in Xero. This is the simplest approach for businesses paying a small number of suppliers.

Batch payments

For businesses paying 10+ suppliers regularly, batch payments save significant time. Select multiple approved bills in Xero, generate a batch payment file (ABA or CSV), and upload it to your bank. All payments go out in one batch. The batch payment reconciles as a single transaction in your Xero account.

Most businesses schedule batch payments weekly or fortnightly. This balances cash flow management with supplier relationship maintenance.

Direct payment integrations

Some accounting software integrations let you pay bills directly from Xero without switching to your bank portal. GoCardless and TransferWise (now Wise) both offer payment initiation from within the Xero interface.

Managing Cash Flow Through Accounts Payable

Your accounts payable timing directly affects cash flow. Pay too early and you tie up cash unnecessarily. Pay too late and you damage supplier relationships or incur penalties. Xero’s AP reports help you find the balance:

  • Aged Payables Summary – total owed to each supplier, grouped by age (current, 1-30 days, 31-60 days, 60+ days)
  • Aged Payables Detail – individual bills with due dates, so you can prioritise payments
  • Cash flow forecast – Xero Analytics Plus shows your projected cash position based on upcoming bill payments

Review the Aged Payables report weekly as part of your cash flow management. If cash is tight, prioritise payments to critical suppliers and negotiate extended terms where possible.

Repeating Bills for Regular Expenses

For expenses that recur at the same amount – rent, insurance, software subscriptions, cleaning services – set up repeating bills in Xero. Create the bill once, click Save as Repeating, set the frequency, and Xero creates the bill automatically each period.

This automates regular accounts payable entries and ensures fixed costs aren’t missed from your accounting records. The repeating bill appears in Awaiting Payment on the scheduled date, ready for approval and payment.

Handling Credit Notes and Adjustments

When a supplier issues a credit note – for returned goods, overcharges, or account credits – record it in Xero as a supplier credit note. Go to Business > Bills to pay > New Credit Note, enter the details, and apply it against outstanding invoices from that supplier.

Xero tracks credit notes separately in your accounts payable and deducts them from the supplier’s balance in the Aged Payables report. This keeps your AP records accurate without manual adjustments.

Accounts Payable Reports in Xero

Key reports for managing your AP process:

  • Aged Payables Summary – what you owe and how overdue it is
  • Aged Payables Detail – individual invoices with due dates and amounts
  • Bills to Pay – all bills awaiting payment, sorted by due date
  • AP Turnover – how quickly you’re paying suppliers on average
  • Account Transactions – full payment history for any expense account

Your accounting team uses these reports for month-end reconciliation, cash flow forecasting, and year-end accounts preparation. Keeping your accounts payable clean in Xero saves time and accounting fees at year-end.

Common Accounts Payable Mistakes

  • Duplicate invoices – entering the same supplier invoice twice inflates your AP balance and leads to overpayment. Use Hubdoc’s duplicate detection or check the invoice reference number before entering.
  • Wrong account codes – coding a capital purchase to an expense account (or vice versa) affects your P&L and balance sheet. Review account code assignments monthly.
  • Missing purchase orders – without a PO, you can’t verify that the invoice matches what was ordered. AP automation tools with three-way matching catch this.
  • Ignoring supplier statements – reconcile your AP records against supplier statements quarterly. This catches missed invoices, unapplied credits, and manual errors and data entry mistakes.

Frequently Asked Questions

What’s the difference between accounts payable and accounts receivable?

Accounts payable is money you owe to suppliers (your bills). Accounts receivable is money owed to you by customers (your invoices). Both are tracked in Xero and appear on your balance sheet. For a complete guide to both, see our accounts payable and receivable article.

Can Xero automate accounts payable completely?

Not entirely – you’ll always need someone to review and approve bills. But Xero with Hubdoc or Dext can automate 70-80% of the data entry and invoice processing work, saving hours every week.

How many supplier invoices can Xero handle?

There’s no limit. Xero handles thousands of bills per month. For high-volume AP processing, add Dext or Lightyear for faster automated invoice capture.

Why Accounts Payable Matters

Good accounts payable management helps you pay bills on time, maintain strong supplier relationships, and avoid late payment penalties. In Xero, your AP data feeds directly into your cash flow forecast, P&L report, and VAT return. When your AP process is clean, everything else in your accounting works better.
