DoubleAgent has always been able to explain invoice payments from your contacts. However until now it relied on your contacts being consistent with the text they used to describe their payment – e.g. their company name – so you could match the text to the specific contact.
Now, as an alternative, you can tell DoubleAgent simply to look for an invoice reference number in the payment reference. Much easier. All your contacts need to do when they pay you is pop the invoice reference in their payment reference, which most people do anyway.
You can read the details in our docs on invoice receipts.
This way of finding the relevant invoice had, for some reason, never occurred to me; it was suggested by a customer. If you have a way DoubleAgent could work better for you, please let me know!
