FAQs

Can I take deposits for heating installations through TradeTally?

Create a deposit invoice for the agreed amount, then a completion invoice for the balance. Both appear on your customer record.

Does TradeTally handle seasonal variations in heating work?

TradeTally tracks your income and expenses month by month, so you can see seasonal patterns and plan for quieter periods.

Can I track boiler warranty information?

Add warranty details in invoice notes or attach manufacturer documentation to the invoice for your customer's records.
