Connect simPRO and Xero: Automate Your Quote–to–Cash Flow

Most trade businesses run two systems that never quite talk to each other. simPRO handles jobs, quotes, and scheduling. Xero handles invoicing, payments, and accounting. And somewhere in between, your office staff spend hours every week re–entering the same data in both places.

A quote gets approved in simPRO. Someone manually creates the invoice in Xero. A payment lands in Xero. Someone walks over to simPRO and marks the job as paid. A new customer gets added in one system – and eventually, when someone remembers, they add them to the other.

It’s slow, error–prone, and expensive. AI agents eliminate the double handling entirely.

The real cost of double data entry

The problem isn’t just wasted time – though that adds up fast. When staff re–enter data between simPRO and Xero manually, you get mismatched customer records, invoices that don’t match job values, payments that aren’t reconciled for days, and cash flow reports that are always slightly out of date.

These small errors compound. An invoice goes out with the wrong amount. A customer gets charged twice. A payment sits unreconciled in Xero while the job in simPRO still shows as unpaid. Your bookkeeper spends half a day each month untangling the mess.

The root cause is simple: two systems that should share a single source of truth, but don’t.

The quote–to–cash flow, automated

Here’s what the full cycle looks like when AI agents connect simPRO and Xero:

1. Quote approved in simPRO. The customer accepts a quote. The AI agent detects the approval and creates a matching invoice in Xero automatically – correct line items, amounts, tax codes, and customer details. No one touches Xero.
2. Job created and scheduled. The job progresses through simPRO as normal – technicians are dispatched, work is completed, and the job is closed out.
3. Invoice sent from Xero. Once the job is marked complete in simPRO, the agent triggers the invoice in Xero to be sent to the customer. Timing is automatic – no more invoices sitting in draft for days.
4. Payment received in Xero. The customer pays. The AI agent picks up the payment in Xero and updates the corresponding job in simPRO to reflect that it’s been paid. Reconciliation happens in real time.
5. Job marked paid in simPRO. The loop closes. Both systems agree on the status of every job, every invoice, and every payment – without anyone lifting a finger.

That’s the entire quote–to–cash cycle running on autopilot.

Customer record sync

One of the most tedious tasks in running two systems is keeping customer records consistent. With AI agents, when a new customer is created in simPRO, the corresponding contact is automatically created in Xero – same name, same email, same billing address. Updates flow in both directions. Change a phone number in simPRO and it updates in Xero. Update a billing address in Xero and it syncs back to simPRO.

No more hunting through two systems to figure out which one has the correct address. No more duplicate contacts cluttering your Xero account. One customer, one record, always in sync.

Payment reconciliation without the spreadsheet

In most trade businesses, payment reconciliation is a weekly or monthly chore. Someone exports data from Xero, cross–references it against simPRO job records, and manually marks jobs as paid. It’s tedious and it means your job profitability data in simPRO is always lagging behind reality.

AI agents close this gap in real time. When a payment is recorded against an invoice in Xero – whether it’s a bank transfer, credit card, or direct debit – the agent immediately updates the corresponding job in simPRO. Partial payments are tracked. Overpayments are flagged. Your simPRO dashboard always reflects the true financial state of every job.

Overdue invoice chasing

Late payments are a cash flow killer for trade businesses. AI agents don’t just track what’s overdue – they act on it. The agent monitors invoice aging in Xero. When an invoice passes your defined threshold (say, seven days overdue), it automatically drafts and sends a polite follow–up email to the customer via Gmail. If the invoice reaches 14 days, a firmer reminder goes out. At 30 days, you get notified to take further action.

Every follow–up is logged. You can see exactly what was sent, when, and to whom. No more relying on someone in the office to remember to chase payments – the agent handles it consistently, every time.

Real–time cash flow visibility

When simPRO and Xero are connected through AI agents, you get something most trade businesses don’t have: a real–time view of cash flow that’s actually accurate.

You can see which jobs have been invoiced, which invoices are paid, which are overdue, and what’s still in progress – all without logging into two systems and mentally stitching the numbers together. Because the data flows automatically and immediately, your financial picture is always current. Not last week’s numbers. Not end–of–month approximations. Right now.

For businesses doing six or seven figures in monthly revenue across dozens of active jobs, this visibility is the difference between confident decision–making and guesswork.

What AI agents can do across both systems

The scope of automation is broad. simPRO’s API exposes over 50 actions – covering jobs, quotes, invoices, customers, schedules, and more. Xero’s API covers invoices, payments, contacts, bank transactions, and credit notes. AI agents operate across both APIs simultaneously, giving them the ability to:

• Create Xero invoices from approved simPRO quotes
• Sync customer and contact records between both systems
• Update simPRO job payment status when Xero receives payment
• Send overdue invoice reminders based on Xero aging data
• Reconcile partial payments and flag discrepancies
• Generate financial summaries combining data from both platforms

Unlike rigid integrations with fixed rules, AI agents adapt. If your invoicing workflow changes or you add new job types in simPRO, you update the agent’s instructions in plain English – no developer required.

Getting started

If your business runs on simPRO and Xero and you’re tired of double–handling data between them, AI agents are the practical fix. Setup takes under an hour – you connect both accounts, define your automation rules in plain English, and the agents get to work. Start with one workflow, like quote–to–invoice sync, and expand from there as you see the time savings stack up.
