Simple Accounting & Tax for a Small HVAC or Refrigeration Business
You shouldn’t need an accounting degree to know if the month was good. R-Pro’s office ERP keeps the books — sales, purchases, expenses and net profit — and the field app feeds the jobs straight in, so the numbers are always current.
The books, kept for you

- Unpaid invoices and money owed, tracked at a glance.
Tax that fits your country

- Sales tax and purchase tax totalled for you for filing.
- It prints on your invoices, receipts and estimates.
Fed from the field automatically
- Jobs logged on site become sales entries in the office books.
- No double entry — the field app and the ERP share one account.

Do I have to be an accountant to use it?
No. The ERP totals your sales, purchases, expenses, profit and tax automatically — you just record the work, which the field app helps with too.
Will it handle my country’s tax?
Yes. You set your own tax name and rate, and the ERP totals sales and purchase tax for filing and prints it on your documents.
Where does the data come from?
Jobs you log on the R-Pro field app flow into the office books automatically, so the accounting reflects real work without re-entry.
