PeriodGuard · Web app
Who changed your books, and when.
PeriodGuard reads your accounting records every hour with read-only access and keeps every version. When something changes, you see exactly what, from what to what, and who did it; when it lands in a month you already closed, you and your accountant get an email.

What PeriodGuard does
Before and after, field by field
Every version of every invoice, bill, payment, bank transaction, manual journal, credit note, contact and account is kept, and each change lists the values that changed.
Who and when
Each change shows who made it and when, from the accounting software’s own history of that record.
Closed months stay closed
An edit, void or back-dated entry in a closed month is emailed at once, using your lock dates or a closed-through date you set. A lock date moved back is emailed too.
A report for your accountant
Every change in a period, before and after, who and when, to print or download as CSV, with all your clients side by side.
Who it’s for
- Small businesses with a bookkeeper or several people in the books
- Accountants and bookkeepers who report or file a month and need it to stay as it was
How it works
- Connect your business with read-only access; PeriodGuard reads every record once.
- Every hour it compares what changed with the version it kept.
- You see each change in the history, and get an email when one lands in a closed month.

Questions about PeriodGuard
Can PeriodGuard change my books?
No. It asks only for permission to read, and refuses a connection that offers more.
Does it show changes made before I connected?
No. It keeps every version from the day you connect, so changes after that show with their value before and after.
What happens to my data if I disconnect?
Everything PeriodGuard stored about that business is deleted. It is never sold, shared or used to train AI.
