How to reduce bad debt and protect your bottom line

Most bad debt is preventable. It builds up when credit goes out without a check, invoices age without consistent follow-up, and warning signs get missed until an account is too far gone to recover. Reducing it means acting earlier across the whole cycle: screen credit before you grant it, invoice cleanly, chase the moment an invoice ages, and watch for the signals that an account is sliding before it hits the 90-plus bucket where recovery odds collapse.

Bad debt is a lagging number. By the time it shows up as a write-off, the chance to prevent it passed weeks or months earlier. The levers that actually move it sit upstream, in credit, billing, and the consistency of follow-up.

What drives bad debt in B2B

Four causes account for most of it:

• Credit extended blind. A new customer gets terms without a credit check, then never pays. The loss was decided at order capture.
• Invoicing friction. A wrong amount, a missing PO, or a bad contact stalls the invoice. It does not get paid, it gets ignored, and it ages.
• Inconsistent follow-up. Accounts are chased by memory, so some slip through. The quietest overdue accounts are often the riskiest, and they get the least attention.
• Customer distress no one caught. The customer hit trouble, started paying everyone slowly, and your team noticed only when the account was already 90 days out.

Notice the pattern. None of these is about chasing harder at the end. They are about acting earlier at the start.

Preventing bad debt upstream

The cheapest bad debt to fix is the one you never book. Prevention starts before the invoice.

Run a credit check at order capture and set a limit that matches the risk. A clear credit policy makes this repeatable instead of a judgment call per order: who gets what terms, what triggers a review, and where the limits sit. Put payment terms in writing and make the due date unmistakable on every invoice.

Then remove the friction that delays payment. Invoice accurately and immediately, carry the PO number the customer's portal requires, and send the bill to the person who actually approves it. Every avoidable delay is a day closer to the account aging into the risk zone. Preventing late payment in the first place is the same work as preventing late payments generally: clean invoices, clear terms, steady cadence.

Early-warning signals to watch

Bad debt announces itself if you are watching. The signals usually appear weeks before a write-off:

• Slowing payments. An account that paid on day 35 starts paying on day 50, then day 65. The trend matters more than any single late payment.
• Broken promises to pay. A customer commits to a date and misses it, then commits again. Repeated broken promises are a strong predictor of default.
• Partial payments and rising disputes. Short pays and new deductions can mask a cash problem the customer is not admitting.
• Crossing aging buckets. An invoice moving from 30 to 60 to 90 days is the clearest signal of all, and the point at which recovery odds drop sharply.

The trouble is that catching these signals across a full ledger by hand is nearly impossible. They get noticed on the accounts someone happens to be looking at, not the ones quietly deteriorating.

Recovering before write-off

Once an account is overdue, recovery is a race against aging. The probability of collecting a 90-plus-day invoice is a fraction of a current one, so speed and consistency matter more than escalation.

Run a firm sequence: a reminder before due, a prompt on the day, then escalating follow-ups at set intervals. Pause the sequence on genuinely disputed invoices and route the dispute to an owner, so you are not chasing money that is legitimately on hold. For accounts that are slipping but still engaged, a structured payment plan often recovers more than a demand letter does. Reserve formal escalation and outside agencies for accounts where engagement has stopped. The fuller playbook for accounts already in trouble is in handling delinquent accounts.

Make the math explicit when you decide how hard to push. The expected value of an aged invoice is its balance times the realistic probability of collecting it, and that probability falls with every bucket it crosses. A $20,000 invoice at 60 days, from a customer who still replies, is worth far more in expected cash than the same balance at 150 days from one who has gone silent. Spending your best collector's time on the recoverable account, and moving the dead one toward write-off or an agency, is how you stop pouring effort into balances that will never land while live ones quietly age behind them.

Setting a write-off policy

A clear write-off policy keeps your books honest and your team focused. It defines when an account moves from active collection to write-off: a threshold in days past due, a documented escalation sequence that was actually followed, and a sign-off level for the amount. Without a policy, accounts either get written off too fast, surrendering recoverable cash, or linger in the aging report long after they should, flattering the numbers.

A write-off is not the end of recovery. Keep written-off accounts in a follow-up flow, because a share of them do eventually pay, and recovered bad debt drops straight to the bottom line.

How Rex reduces bad debt with early action

Rex shrinks bad debt by acting before invoices go bad, across every account, every day. It works the whole ledger continuously, so the quiet account sliding from 35 to 65 days does not escape notice. It reads the early-warning signals, slowing payments, broken promises, rising deductions, and steps up follow-up on the accounts that need it while leaving the reliable ones alone.

Because Rex never lets a current receivable drift unattended, far fewer accounts ever reach the 90-plus bucket where recovery collapses. It chases consistently, pauses on real disputes, proposes payment plans where they fit, and escalates the cases that need a human decision. The result is fewer write-offs from the same book, without adding collectors.
