Why this helps
Invoice follow-ups are easy to postpone when they require finding a document and re-entering an address.
- Reduce the steps between deciding to follow up and sending a notice.
- Require an approved notice PDF and confirmed postal details.
- Keep sensitive billing correspondence deliberate and reviewable.
Setup
Build it in a few focused steps.
- 1Connect Telegram and Docupost to Notis once in the portal.
- 2Create the automation in the portal or ask Notis to create it conversationally.
- 3Give one plain-language instruction to mail an overdue notice only after you approve it and the recipient, address, sender, and final PDF are confirmed.
- 4Choose the Telegram new message trigger and a reporting channel.
- 5Test with one approved notice and confirm the billing address before sending.
Questions about this workflow
Will every overdue invoice mention trigger a letter?
Instruct Notis to require an explicit approval to mail, along with the final notice and verified recipient details.
Can I use this for a postcard reminder?
A postcard can be used if you have approved front and back images and have configured the instruction for that format.
