Termite & WDO

Cash Flow for Inspectors: Field-Proven Ways to Invoice and Get Paid Faster

Published October 12, 2026 · 6 min read · By the Inspection Authority team

Why faster payments matter (and what I stopped doing)

After 20+ years inspecting homes and treating WDO jobs, I stopped treating invoicing like an office task I’d get to "later." Slow invoices mean slow cash, more chasing, missed payroll and an ugly pile of unpaid work. Here are the exact, field-tested steps I use to shorten the invoice-to-cash cycle and reduce admin time.

Immediate actions you can do from the truck

1) Invoice before you leave the property

I finish photos, notes and the report on my tablet, then generate the invoice from the same app. Sending the invoice while the customer is still on site removes excuses. Use a one-click "Pay Now" link and offer card or ACH on the spot.

2) Get an e-signed work authorization up front

Before I start a treatment or a detailed WDO scope, I send a two-line work authorization with e-signature and payment terms. Once signed, the customer is committed and I can attach that authorization to the invoice — no surprises, no argument about scope.

3) Ask for deposits when the job justifies it

For large termite treatments or commercial jobs I require a 30–50% deposit. Say it plainly when scheduling: "We’ll need a 30% deposit to confirm materials and booking—how would you like to handle that, card or ACH?" Deposits cut cancellations and speed payment.

Payment methods and the tradeoffs

Method Time to clear Typical fee Best use
Credit/Debit Card Instant authorization, 1–3 days to bank 2.5–3.5% On-site payments and convenience
ACH / Bank Transfer 1–3 business days 0.5% or fixed low fee Large invoices, lower fees
Bank Deposit / Check 3–7 days or longer Free but slow Preferred by some business clients
Recurring Auto-pay Automatic monthly Varies Pest control service plans

Concrete scripts and email text that work

When I'm wrapping up on-site I use two short scripts depending on the client:

My follow-up email is one paragraph: what was done, total due, due date, a clear pay link, and a line about late fees. Keep it short—people read short emails.

Automations and reminders that don’t feel pushy

Automate three messages: invoice sent, reminder at due date, and final notice after 7 days past due. Use plain language and one-click pay in every message. Automated reminders recover a lot of overdue cash without manual calls.

Banking and bookkeeping habits that save hours

Recurring billing for pest plans: set it and forget it

Pest and service-plan billing is the easiest place to win. Set up recurring billing with auto-pay and offer a small discount for cards on file. That predictable revenue smooths cash flow and reduces invoicing time by weeks.

Handling disputers and slow payers

If someone disputes an invoice, I pull the signed work authorization and photos, email a two-paragraph explanation, then call. Documentation ends 90% of disputes. For chronic slow payers I require prepayment or stop-service notices with a clear collection timeline.

Tools I use in the field (why they matter)

Final checklist before you leave the job

Wrap-up: small changes, big impact

I tightened payment times by making payment an on-site step, documenting authorization, and automating reminders. Those three changes alone cut average days-to-pay in half. Do the invoice and payment steps while you’re still in the customer’s driveway—your bank account will thank you.

Frequently asked questions

Should I require deposits for termite or large WDO jobs?

Yes. For treatments or big projects I require 30–50% deposit. It secures booking, covers materials and reduces cancellations.

Which payment method speeds cash flow most?

Credit card with instant authorization and daily payouts is fastest for access; ACH is cheaper and typically clears in 1–3 days.

How do I reduce invoice disputes?

Use signed work authorizations, attach photos and a short scope to the invoice, and include clear terms—documentation settles most disputes quickly.
