Throughout PestaRoo, we have safeguards to help you. Two examples: 1)  If you type in a phone number, PestaRoo quickly turns the number to red if you skip or add an extra digit.  Great way to catch errors! Correct the number… and it instantly reverts to black type.  2) If a customer has an existing credit, and you post an invoice, PestaRoo  will create a warning to let you know that you might want to use that credit. PestaRoo has dozens of other safeguards helping to keep your data clean.
