Text past-due Rent Manager tenants a personal rent reminder

1. Open the Rent Manager Delinquency List tile and set Days to Include (it defaults to 10) to see which tenants are behind.
2. Open each tenant and read the transaction ledger to see whether the balance is unpaid rent, a late fee posted by Task Automation or a one-off charge.
3. Open the tenant's History/Notes tab to check for a promise to pay, a payment plan, or an AR Automation notice that already went out this week.
4. Write the message to each tenant by hand, or use Text Broadcast, which sends the same mass text to many tenants at once.
5. Repeat for every tenant on the list, every week. A tenant who promised to pay on Friday easily gets the same reminder as one who ignored three notices.

Find Maple Court tenants who owe more than $500, check their ledger and History/Notes, and text a personal reminder to the ones who have not promised a payment date. Log each text.

1. 01

   Start from your threshold, not the whole rent roll

   The agent asks list_tenants for current tenants of the property you name, with min_balance set to the amount you gave. Past tenants are left out on purpose: a moved-out balance is a collections matter, not a friendly text.

2. 02

   Find out what the balance is made of

   For each tenant, get_tenant_ledger covers the last two or three months. The agent separates unpaid rent from a single late fee or a utility charge, and it skips anyone whose ledger shows a payment in the last two days that has not cleared the balance yet, because that money may still be posting.

3. 03

   Respect what your team already agreed

   get_history shows the newest History/Notes entries. A promise to pay with a date still in the future, an active payment plan, or an AR Automation notice sent in the last few days puts the tenant on a hold list with the reason, instead of a second message.

4. 04

   Show every draft before anything goes out

   Each draft names the amount and what it is for ("October rent of $1,200 plus the $50 late fee"). You see the full batch, edit a line or drop a tenant, and each send_text waits for your OK by default.

5. 05

   Record the text where the next person looks

   After a text is sent, add_history_note writes the amount and the wording summary to that tenant's History/Notes. If a tenant has no contact set up for texting, the agent does not guess a number; it lists them for a call or a letter.

Maple Court, balance over $500: 6 tenants
Texted: Jordan Lee 4B ($1,250: October rent + $50 late fee), Maria Gomez 9C ($615: utility charge from 2 Oct), Ken Walsh 14A ($1,180: October rent)
On hold: Priya Shah 12A, note of 8 Oct promises payment on 17 Oct
On hold: Tom Reyes 3D, AR Automation notice sent yesterday
No text contact: Alan Park 6B, $720, call or send a letter
History/Notes updated for the 3 texted tenants

• Rent Manager AR Automation alerts are not sent on their own until Task Automation is enabled for Accounts Receivable.
• The AR Automation Balance Filter decides how large the balance must be before an alert goes out, with less than, greater than or equal to rules.
• Rent Manager attaches a record of each AR Automation notice to the tenant's History/Notes tab once it is sent, so the notes show what the tenant already received.
• Rent Manager can post late fees through Task Automation without anyone clicking, so a balance may already include a late fee by the time a follow-up text is written.
• Text Broadcast in Rent Manager sends one mass text to many tenants in seconds, so it cannot name each tenant's own balance.

send_text asks for your OK by default. To run it weekly without you, switch confirmation off for that tool in your dashboard.
