“I also liked how the calls were recorded.”

Jason P.

Owner

Pros

“I have to enter my client name in three places, manually change invoice number with each client, etc..”

Stephanie H.

Landscaper

“Would be good if in the descriptions of work items we can add more than 1400 letters in our case it limits our descriptions and detail of our scope of work to our clients”

Nick L.

Plumbing

“I really like the ease of generating accurate invoices and saving line items for future use, huge time saver”

Craig W.

Owner

Cons

“It got too pricey for us.”

Jason P.

Owner

“Price a bit high and features very difficult to master”

Djabire M.

Manger

Cons

“I wish it didn’t automatically save the job line items but rather face you the option to save. When adding the line item it is automatically on save and I have to remember to turn it off.”

Robert M.

Owner

“I am unable to generate down-payment invoices with a balance due option.”

B G.

Owner

“I don't know why this is a problem but I cannot email anyone and invoice through this app.”
