What I’d start with
One completion form, one set of agreed rates and one Xero organisation.

CLEANING COMPANIES
For a small cleaning company with a team out on jobs and an owner catching up on invoices later. Put completed work straight into the review queue.

THE PROBLEM
The team has cleaned three properties, but the hours and extras are in separate messages. You still have to match each job to the customer, check the agreed rate and type it all into your accounts software.
THE SOLUTION
I’d start with a simple completion form that references the booked job. The workflow would validate the customer and agreed rate, then create a draft invoice only when the required details are present.
Record the job ID, hours, completion status and any agreed extras.
Match the customer, approved rates and work completed. Check for an existing invoice.
Prepare invoice lines in Xero and link the original job sheet.
Review the amounts and any exceptions, then approve and send from Xero.
WHEN SOMETHING NEEDS CHECKINGUnknown rate, disputed hours or an unapproved extra?
Hold the job for review and explain what needs checking. Don’t invent a price or quietly leave out the extra.
WHAT YOU GET
Work through completed jobs as a queue, with the original sheet alongside the draft, instead of rebuilding every invoice from messages.
This example shows the exception path. A fully approved job would proceed to a draft invoice. Sending the invoice stays with you in this first version.
INTEGRATIONS & HOSTING
| Tool | Its part in the workflow |
|---|---|
| Microsoft Forms & Lists | Collect the completion sheet and look up the booked job, customer and agreed rates. |
| Xero | Creates a draft invoice through the Accounting API after checks pass. Job-to-invoice references prevent duplicates. |
| Outlook | Tells you which drafts are ready and which jobs need a decision. |
I’d use Power Automate for the completion workflow and a small custom connection to the Xero Accounting API. A ready-made connector could be used if its capabilities and costs suit the job.
The workflow would run in your Microsoft cloud environment; a custom Xero connection could run on Azure Functions. Invoices stay in Xero. Hosting, account ownership, Xero access and connector charges would be agreed.
A SENSIBLE FIRST PROJECT
One completion form, one set of agreed rates and one Xero organisation.
Count completed jobs awaiting an invoice and compare the time spent preparing each draft.
Drafts need your review. Each job is linked to at most one draft; mismatches and failed connections appear in an exception list.
