Why accounting firms use bSign

Tax season, without the chasing.

The whole client list in one send

Upload a spreadsheet of names and emails and every client gets their own copy to sign. Reminders go out by themselves until it is done.

T183s with a date and time on them

The CRA accepts electronic signatures on forms T183 and T183CORP. bSign puts the signer's name and the date under each signature and records the exact time on the certificate of completion, which the CRA recommends you keep.

Clients sign from their phone

No account, no app and no printer. A personal link opens the form and walks the client through the boxes that are theirs.

Filed where you keep client files

Connect OneDrive, SharePoint, Google Drive, Box or Dropbox and each signed form and its certificate save themselves into the folder you choose.

A template for every engagement

Set up each letter once with its fields in place. Change the names and the fee, and it is on its way.

A flat price per person who sends

You pay for the people on your team who send documents. Signers are free and unlimited, and each plan includes documents every month.

How it works

From upload to a sealed PDF in three steps

No training needed. Most documents go out in under two minutes, and signers finish on the device they already have in their hand.

01

Upload or pick a template

Drop in a PDF or Word file, or start from a template you made once. Drag the signature, date and text boxes where they belong.

02

Send, or hand over a tablet

Each person gets their own link by email and signs on any phone or computer, with no account. In the room with you? They sign on your screen.

03

Sealed, and filed for you

Everyone gets the sealed PDF and its certificate of completion. A copy saves itself to OneDrive, SharePoint, Google Drive, Box or Dropbox if you connect one.

Your part of the T183

The CRA expects whoever receives the signed form to have verified the client's identity, and to keep the form and its date-and-time record. bSign records how and when each form was signed; confirming who your client is remains your step. See the CRA's page on using electronic signatures.

Questions

What accounting firms ask us

Something else? Write to support@binarium.ca.

Does the CRA accept electronic signatures on the T183?

Yes. The CRA accepts electronic signatures on forms T183 and T183CORP, among others. It asks for a date-and-time stamp on certain forms and expects the party receiving the form to have verified the signer's identity.

Can I send the same letter to all my clients at once?

Yes. Bulk send takes a spreadsheet of names and email addresses and creates a separate document for each client, so nobody sees anyone else's copy.

Do my clients need an account?

No. They open a personal link from their email and sign on any phone or computer. You can require a one-time code sent to their email first.

How long are signed forms kept?

As long as you choose. Leave documents in bSign, set a retention period that matches your record-keeping rules, or have every signed copy saved to your own storage.

Where is client information stored?

In Canada, on servers operated by Binarium, an Ontario IT services company.

What does it cost?

The free plan covers 1 user and 5 documents a month. Paid plans are priced per user who sends, with documents included each month; signers never pay. See pricing.
