The practical details

A few questions.
Clear answers.

About your workflows, data and everyday work.

Do I need internet to use the app?

No. Only e-mail, Google Drive backup, cloud lead import, licence and updates need it.

Can I lock the app with a password?

Yes. Set a master password; a recovery key and recovery e-mail code help if you forget it.

Can I bill clients in USD or other currencies?

Yes. Invoices show the client's currency, while your accounts, profit and team pay stay in ৳ BDT. Exchange gain or loss is recorded automatically.

What if a client pays before I send an invoice?

It is saved as a client advance and deducted from the next invoice automatically.

Can I use my own e-mail accounts?

Yes — add as many sender accounts as you want, each with its own daily limit and signature. Gmail uses an App password.

Does Lead Checker change my main leads database?

No. It works only on the sheet you upload.

Are my passwords sent to a server?

No. bdi4 Pass encrypts and decrypts everything on your computer.

Can I move my data to a new computer?

Yes. Back up to a USB drive or Google Drive, install the app on the new computer, and restore.

Can I export data for my accountant?

Yes — CSV exports and printable PDF reports for Profit & Loss and the Balance Sheet.
