Relationship-safe invoice chasing for trades

A tool that politely reminds trade customers to pay overdue invoices.

TIME TO START2 to 3 days
FIRST PRICE$99 setup
WEEKLY WORK3 to 6 hours
FIRST CUSTOMERA local trade business

01 / THE PROBLEM

Owner-operated plumbing, electrical and HVAC businesses that invoice after the job.

The money is owed, but asking for it can feel awkward. General invoicing tools can send reminders, yet they do not always solve the emotional job of preserving a customer relationship while getting paid.

THE CONCEPT

A deliberately small follow-up tool or service. It creates polite, escalating text sequences, pauses when a customer replies, and keeps the owner in control. It does not try to replace accounting software.

02 / WHAT YOU SELL

A clear starter offer, not a vague business.

The customer receives

  • A three-message reminder sequence in the owner's voice
  • A simple overdue-invoice tracker
  • Weekly follow-up with replies handed back to the owner

How to price it

  • Pilot: $99 for up to ten overdue invoices
  • Monthly: $149 to $299 depending on volume
  • Keep collected money out of your accounts
SIMPLE REVENUE EXAMPLE

Five clients paying $199 a month would produce $995 in monthly revenue. The key question is whether each account can be handled in under one hour a week.

03 / FIND THE FIRST CUSTOMERS

Start where the problem is already visible.

Where to look

  • Ask local plumbers, electricians and HVAC firms how they chase late invoices
  • Partner with a bookkeeper who does not offer collections
  • Post a sample polite reminder sequence in a local trade group

Your first seven days

  1. 01Write three polite reminder templates
  2. 02Show them to five trade owners
  3. 03Run one pilot using dummy data first
  4. 04Charge for a ten-invoice batch before building software

04 / THE EVIDENCE

What we know. And what we do not.

  1. 01

    A founder described watching a tradesperson repeatedly struggle with overdue-payment follow-up and proposed an SMS-first solution.

  2. 02

    InvoiceASAP markets accounts-receivable management to field-service businesses, while QuickBooks already supports automated invoice reminders. That confirms an active category, not an open market.

  3. 03

    An idea-miner snapshot recorded a Starter Story profile reporting $85K monthly revenue for InvoiceASAP. We have not independently verified that figure.

05 / THE SMALLEST TEST

DO THIS BEFORE YOU BUILD

Ask five trade owners you already know, or have permission to contact, to review a fictional three-message sequence. Do not use real debtor data. Show where it would sit beside their current invoicing tool.

PASS CONDITION

Two owners agree to a workflow discussion and one asks for a sample, trial or follow-up. Cap the test at two hours and $0.

06 / WHAT THE WORK LOOKS LIKE

What you would actually do each week.

  1. 01

    Review the approved overdue list

  2. 02

    Send or schedule reminders

  3. 03

    Pause when a customer replies

  4. 04

    Report outcomes and awkward cases to the owner

07 / THE TENSION

Reasons to lean in. Reasons to walk away.

Why it could work

  • The emotional job is more specific than generic invoicing.
  • A service-led start can test the workflow before software.
  • The tool can complement systems owners already use.

Why it could fail

  • Incumbents may already be good enough.
  • Messaging consent and compliance add operational risk.
  • Interest in polite wording does not prove willingness to switch or pay.

08 / COMMON QUESTIONS

The things to settle before taking money.

Is this debt collection?

It should begin as administrative follow-up only. Do not threaten action, give legal advice or present yourself as a collection agency.

Why would a trade pay when invoicing software sends reminders?

They may not. The offer works only if personal wording and managed follow-up save the owner time or preserve customer relationships better than automation alone.
