Send from your office

You prepare the letters. We take care of the rest.

A courier collects the package of correspondence and delivers it to BackOffice. After receipt, we prepare posting within the service scope you selected.

Two service options - check before signing in

Both options include collection and posting at the post office. The difference is who processes the letters, prepares the posting documents and settles postage.

Option 1

Collection and posting with mail processing

BackOffice processes your mail and prepares it for posting.

Your preparation

Put each letter in a separate envelope. Add legible sender and recipient addresses and mark it as an ordinary letter, registered letter or registered letter with acknowledgement of receipt (ZPO - yellow card).

Posting documents

BackOffice prepares mailing lists and posting books and handles acknowledgements of receipt (ZPO yellow cards), as ordered.

Postage

BackOffice includes postage in the estimate and settles actual costs. You do not need your own stamps or a postage-paid agreement.

What BackOffice does

We collect, sort and process the letters, prepare the posting documents and post the mail.

Letter counts in the form

Enter the counts of ordinary letters, registered letters and registered letters with acknowledgement (ZPO).

Option 2

Collection and posting without mail processing

You prepare the complete mailing, ready for posting.

Your preparation

Supply addressed, marked and postage-paid mail that is fully ready for posting.

Posting documents

Prepare these yourself. All required posting documents must be correctly completed, and you must confirm this in the form.

Postage

Settle postage directly with Poczta Polska. Choose one of the following two methods:

  1. Postage stamps - correctly affixed to every item. You accept full responsibility for the correct postal rates and postage payment.
  2. A postage-paid agreement with Poczta Polska - Urząd Pocztowy Warszawa 4. You must enter the postage-paid reference number in the form.

Stamps are paid for when purchased; contractual postage is charged by Poczta Polska under your agreement.

What BackOffice does

We collect the prepared mail and post it. This option does not include letter processing, preparation of posting documents or postage charged by BackOffice.

Letter counts in the form

No letter counts are required.

If you do not meet the conditions for collection without processing, choose collection and posting with mail processing and enter the letter counts.

Choose a standard date from those available in the form. The courier’s estimated time window is shown after the carrier accepts the booking. Collection hours are not fixed or guaranteed. The courier’s estimated window appears after booking the courier.

Three steps for you

01

Prepare and mark your letters

Put each letter in a separate envelope. Add legible sender and recipient addresses and mark the envelope as “ordinary letter”, “registered letter” or “registered letter with acknowledgement of receipt (ZPO - yellow card)”.

02

Book our collection

Select a collection location, available date and service scope. Provide a contact and use the courier instructions to state exactly where the envelope will be waiting. Enter letter counts if required by your selected scope.

03

Secure the package and hand it over

Pack the letters in a sealed courier envelope or box. After booking, print the courier label and attach it outside, and put the order-reference label inside. Leave the package at the location specified for the courier.

What we do with mail processing included

  • We sort and process ordinary, registered and registered letters with acknowledgement of receipt (ZPO).
  • We prepare ordinary mail lists and registered mail posting books.
  • If yellow ZPO acknowledgement cards are missing, we complete them and attach them to the letters.
  • We post correspondence after it reaches BackOffice and is processed. The courier’s collection day is not the day the individual letters are posted.

After posting: proof and tracking

You receive scans confirming posting and access to our system. You can track registered letters using their assigned R numbers.

Need the originals?

Choose the document return method and price in the form. Courier return is a separate trip billed at the accepted price.
