When Your Business Software Stops Talking to Each Other
Your job system, accounting software, and CRM are all running fine — just separately. Here is what that actually means for your business, and what fixing it looks like.
A trades business runs Simpro for jobs. Xero for accounting. Every Friday, someone manually exports invoices from Simpro and imports them into Xero. When they forget, the bookkeeper spends Monday morning figuring out what's missing.
This isn't a hypothetical. It's a pattern we see every few weeks.
The problem isn't the software. Both tools are good at what they do. The problem is the gap between them — and the person filling that gap with copy-paste, every single week.
Most growing businesses hit this at some point. The tools that worked fine when the team was small start showing cracks as volume increases. Job systems, accounting platforms, CRMs, and spreadsheets each doing their job — just not talking to each other.
Signs something is broken
These are the ones we hear most:
- Someone on your team has a recurring end-of-week task that involves downloading something from one system and uploading it to another
- Your job numbers don't always match your invoice numbers because someone re-entered them manually
- A client didn't get their service reminder because the export didn't happen that week
- Your admin team checks three different places before they can answer a simple question about a job's status
- You moved to a new accounting platform two years ago and still haven't fully migrated because someone needs to clean the data first, and nobody has time
- You bought a CRM and it's basically a very expensive contacts list because nothing feeds into it automatically
None of this is unusual. But it does compound. The manual steps that take twenty minutes now take an hour at double the volume. The errors that were rare become regular. Staff who should be doing other things spend their morning doing data entry.
Examples from the field
Simpro to Xero invoice sync
Simpro generates invoices when jobs are completed. Xero is where the bookkeeper lives. Without a sync, someone exports from Simpro and re-imports to Xero — or types them in again. Jobs that don't get invoiced don't get paid. The manual process works until it doesn't.
With a proper integration: invoices push from Simpro to Xero automatically when a job reaches the right status. Tax codes are mapped correctly. Customer records are matched, not duplicated. If something can't sync — a missing contact, a code mismatch — it's flagged in a log, not dropped silently.
The time saved isn't the main benefit. It's the accuracy. Invoices that are created in Simpro appear in Xero the same day, not the following Monday.
Tradify automated service reminders
A services business using Tradify wants to SMS clients two days before a scheduled job. Tradify doesn't do this natively. The workaround is someone checking the next two days' jobs each morning and texting clients from their own phone. Some days it happens. Some days it doesn't.
The fix: when a job is scheduled in Tradify, a trigger fires 48 hours before and sends the client an SMS through an Australian gateway. Automated, logged, and it goes out whether anyone remembers to check or not. Clients show up. Jobs don't get wasted.
Monday.com connected to Simpro
Some businesses use Monday as their project and account management layer — account managers live in Monday, field teams live in Simpro. Without a connection, a job's progress in Simpro is invisible to the account manager until someone updates Monday manually, which may or may not happen.
With a sync in place, Simpro job status changes reflect in Monday automatically. Account managers see live progress without needing Simpro access or waiting for someone to update a board. Fewer "what's the status on this?" messages. Less chasing.
MYOB or Reckon migration to Xero
This comes up a lot. Businesses on MYOB or Reckon wanting to move to Xero for cloud access, proper bank feeds, and better integration options. The native migration tools get you about 80% there.
The 20% is the problem. Customer records that don't match. Transaction history that imports with the wrong dates or categories. Payroll data that needs manual verification. Tax settings that work differently between platforms. A rushed migration creates months of reconciliation headaches.
A clean migration involves auditing the source data first, mapping every field, running both systems in parallel for a period, and verifying that opening balances match before the old system is turned off. It takes longer. It's worth it.
Why native connectors fall short
Simpro, Xero, Tradify, and most other platforms have integration marketplaces. Some of those connectors work fine for standard setups. The issue is your business isn't a standard setup.
Your invoice line items have a cost centre structure that doesn't map cleanly to Xero's chart of accounts. Your Simpro job statuses include custom stages the connector doesn't know about. Your Tradify customer records have a secondary contact field that the standard sync skips entirely.
When there's a mismatch, one of two things happens: the connector fails and you get an error notification, or it pushes wrong data and you don't find out until reconciliation. Neither is great when you're syncing financial records.
Off-the-shelf connectors are built for the median business. If your processes are close to the median, they're fine. If you have specific rules — and most businesses that have been operating for a few years do — you'll hit walls quickly.
What a custom integration covers
When we build an integration, here's what's actually involved:
API review. Before any code, we understand both endpoints. What does the Simpro API actually expose for invoices? What are the Xero rate limits? Are there known issues with specific object types? This step prevents surprises mid-build.
Data mapping. Every field, every code, every status. Where does Simpro's "Awaiting Parts" map in Xero? What happens to a Simpro contact that doesn't exist yet in Xero — create it, skip the sync, or flag it? These decisions get made upfront and documented, not discovered in production.
Automation rules. The logic that makes the integration yours. Not just "sync invoice when created" but "sync invoice when status is Approved AND job type is not Internal AND customer is not on hold in Xero." The rules that match how your business actually works.
Error handling. What happens when an API call fails? Does it retry? How many times? If it can't recover, does it alert someone? Does it log enough detail that the problem can be diagnosed without calling us? A sync that silently drops records is worse than no sync at all.
Logs and reporting. Not a complex dashboard — just a record of what was processed, when, and whether anything needs attention. Something someone can check in thirty seconds each morning. When something breaks, the log tells you exactly what failed and why.
If you're not sure whether your situation warrants a custom integration or whether there's a simpler fix you're missing — that's exactly what a system review is for. We look at what you're running, where the gaps are, and give you a straight answer before any project starts.
