A day with the accounts receivable specialist
Wake to bed.
11 waypoints. 2 peak-stress hours.
Aging report
Coffee, headset, AR aging report on the second monitor. Forty-seven invoices over thirty days, eleven over sixty, two over ninety she has been trying to land for a month. Highlights the six she will work today before she opens email.
Invoices out
Pulls yesterday's completed jobs from the field and sends invoices on each — same-day billing, the rule the Controller wrote on the whiteboard her first week. Twelve residential, two light-commercial; each goes out with the tech's notes and photos attached.
Collection calls, friendly first
Starts the cadence calls coming straight out of the eight o'clock stand-up — thirty-day bucket, the still-friendly conversations. Customer history pulled up on screen for each: open invoices, payment patterns, last conversation note. Three pay over the phone with a card; one promises Friday and she logs the promise verbatim.
Dispute, AC install
Customer calls in hot about a $9,400 install invoice — claims a thermostat upgrade wasn't included in the quoted price. Pulls the signed estimate and the change order, walks the customer through it line by line. Voice stays even; the line-item history makes the case without her having to.
Payment posting
Lockbox file from the bank lands. Posts twenty-three payments against open invoices, two come in short and need a customer call, one is from a customer she didn't expect — applies it and emails a paid-in-full receipt with a thank-you.
Lunch in the breakroom
Heats the soup her husband made, eats with the Bookkeeper. Five minutes about the Bookkeeper's daughter's piano recital, five minutes about the supply-house bill that got flagged this morning, then back to the headset.
Sixty-day calls
Harder cadence now. Less friendly, still not adversarial — the Controller's framing she keeps in her head. Two customers agree to payment plans she has authority to approve, one she has to escalate to the Service Manager before more work is booked.
Dispute resolution
Closes the loop on the morning install dispute. Customer agrees to the original total minus a $200 goodwill credit she walked through the Service Manager. Documents the conversation, the credit memo, and the new payment date in the customer record.
Ninety-plus review
Two accounts over ninety days. One is a builder she has worked with for years — calls the owner, not the AP clerk, and gets a wire commitment for tomorrow. The other goes to the Controller with a recommendation to send to outside collections.
DSO check
Pulls the running DSO number. Down a day from last week, three days from quarter-open. Screenshots it for the Controller's Friday packet so the trend is on the record.
Day close
Logs every collection conversation from the day in the customer notes — paraphrase plus the promise date. Sets tomorrow's call list, leaves the sixty-day bucket on top.
