How to Write a Customer Credit Policy: Credit Limits, Payment Terms, and Collection Triggers

Your best sales month on paper can be your worst month in the bank account. Every invoice you send on Net 30 terms is an interest-free loan you made to a customer — and unlike a bank, you probably underwrote it in about ninety seconds, based on a handshake and a feeling. When those loans come back late, the damage is not theoretical: a 2026 Bluevine survey of 1,052 U.S. small business owners found that 29% had delayed their own paychecks because customers paid late, and nearly 1 in 6 had struggled to meet payroll for the same reason.

A written customer credit policy fixes this. It is the document that decides — before the sales call, not during it — who gets credit, how much, on what terms, and what happens when payment does not arrive. Without one, every credit decision becomes a negotiation, and collections start whenever someone finally notices the aging report.

This guide walks through the five building blocks of a policy that protects your cash flow without starving your growth: approval criteria, credit limits, payment terms, collection triggers, and the paperwork that makes it all enforceable.

Why a Written Policy Beats Case-by-Case Judgment​

Three problems show up in every business that extends trade credit informally:

Sales and finance pull in opposite directions. Sales will promise generous terms to win the order; finance would prefer payment upfront. A written policy settles the argument in advance by pre-approving standard terms and defining exactly who can authorize exceptions.

Your riskiest customers negotiate hardest. The customer demanding Net 60 with no credit check is telling you something about how they manage payables. A policy with standard tiers means the answer is "our standard terms for new accounts are X" instead of a bespoke decision under pressure.

Inconsistency creates legal and relationship risk. Charging one customer a late fee while waiving another's invites accusations of favoritism — and in some contexts, discrimination claims. A policy you apply evenly is both fairer and easier to defend.

The scale of the problem keeps growing. Atradius's 2025 survey of North American B2B payment practices found overdue invoices now account for 42% of B2B sales value, with average payment terms stretching to 45 days. You cannot control how fast customers pay. You can control the system that decides who owes you money.

Building Block 1: Who Gets Credit​

The first section of your policy defines your approval criteria — the bar a new customer clears before you ship anything on open account.

Require a signed credit application, every time​

No application, no terms. The application does three jobs at once: it collects the information you need to underwrite, it puts the customer on notice that credit comes with conditions, and the signature turns your terms into an enforceable agreement.

A solid B2B credit application captures:

• Legal business name, trade name, billing and shipping addresses, and years in business
• Business structure (corporation, LLC, partnership, sole proprietorship) and owner or officer names
• Bank name, account type, and a contact who can confirm the relationship
• At least three trade references — vendors currently extending them credit terms, with contact details
• Requested credit limit and expected monthly purchase volume
• Written consent for you to pull business credit reports and contact references
• Your payment terms, late-fee policy, and collection-cost clause, acknowledged by signature

Actually check the references​

Skipped verification is where most small-business credit losses begin. Call at least two trade references and ask three questions: How long have they sold to this customer on terms? What is the customer's typical payment pattern — pays on time, pays at 45 on Net 30 terms, or needs chasing? And would they extend more credit today? A reference who hesitates on that last question has told you everything.

Pull a business credit report too — payment history, public records, and failure-risk scores. For larger exposures, ask for financial statements — at minimum a recent balance sheet — and look at the trend, not just the snapshot. A profitable company with deteriorating liquidity is riskier than a thin-margin company with steady cash.

Sort customers into tiers​

Not every approved customer deserves the same deal. Most small businesses do well with three tiers:

• Tier A (established, strong history): standard terms, higher limits, eligible for early-payment discounts.
• Tier B (acceptable with limits): standard terms with a conservative starter limit, reviewed after six months of on-time payment.
• Tier C (new, thin file, or blemished): prepayment or reduced terms (e.g., Net 15), deposits on larger orders, and a path to better terms spelled out in writing.

Tiers turn "we don't trust you yet" into "here is exactly how you earn better terms," which preserves the relationship while protecting you.

Building Block 2: How Much Credit to Extend​

A credit limit is the maximum outstanding balance a customer can carry — not per order, but total across all unpaid invoices. Setting it is where generosity meets arithmetic.

Start conservative, then earn upward​

A common starter formula for new accounts is the lesser of two numbers: roughly one month of the customer's expected purchases, or an amount you could write off without missing payroll. Every credit limit is a bet sized by what you can afford to lose — and new customers have not given you evidence yet.

From there, grow limits on evidence, not enthusiasm. A practical rule: after six consecutive months of on-time payment, consider raising the limit toward two months of average purchases. Tie increases to behavior — payment punctuality, order consistency, updated financials — and document the reason for each change.

Set a concentration ceiling​

One customer's limit should never be large enough to sink you. Many businesses cap any single account at 10 to 20 percent of total receivables, with anything above that requiring owner approval and extra protection — a personal guarantee, a letter of credit, or credit insurance. If your largest customer represents a third of your receivables, you do not have a customer; you have an investor who never signed anything.

Review limits on a schedule, not on a hunch​

Creditworthiness decays. A customer who was solid two years ago may have new ownership, new debt, or a shrinking industry. Your policy should require a periodic review — annually for Tier A, every six months for Tier B, quarterly for Tier C — plus event-driven reviews when you spot warning signs: suddenly larger orders, changed payment patterns, bounced payments, ownership changes, or news of layoffs and lawsuits. Downgrades feel awkward; formalizing them as "scheduled review" makes them routine.

Building Block 3: Payment Terms, Discounts, and Deposits​

Terms are the price of your credit. This section of the policy sets your standard terms, your early-payment incentive, your deposit rules, and your late-payment consequences.

Pick standard terms that match your cash cycle​

Net 30 remains the small-business default, since it roughly matches a monthly operating cycle. But "standard" should reflect your reality: if your suppliers demand Net 15 while you grant Net 45, you are financing the gap out of working capital. Match your industry's standard to stay competitive, and make longer terms something customers qualify for rather than assume.

Spell out exactly when the clock starts (invoice date versus delivery date matters for shipped goods), which payment methods you accept, and where payment goes. Ambiguity here is a common source of "we thought it meant…" disputes.

Use early-payment discounts deliberately​

Offering 2/10 Net 30 — a 2% discount for paying within 10 days instead of 30 — is one of the cheapest accelerators of cash flow available to a small business. The discount costs you 2% of the invoice; skipping it costs the customer the equivalent of more than 36% on an annualized basis, which makes taking it one of the best returns your customer can earn anywhere. Frame it that way when you offer it: it is not a price cut, it is a reward for fast cash.

On thin margins, though, a standing 2% discount can cost more than carrying the receivables — reserve discounts for customers whose volume justifies them, or for periods when you specifically need cash in.

Require deposits where the risk concentrates​

Deposits are not just for contractors. Any order involving custom work, special-order materials, or significant upfront cost should require money before you begin — commonly 30 to 50 percent, with progress payments on longer engagements. Define the deposit threshold in the policy — all orders over a set amount, say, or all custom work — so it applies automatically. Customers who object to a reasonable deposit on custom work are previewing how they will handle the final invoice.

State late fees and enforce them evenly​

A late-payment charge — commonly 1 to 1.5% per month on overdue balances — compensates your carrying cost and moves your invoice to the top of the customer's pay stack. Three cautions: check your state's late-charge and usury rules first, since a standard rate in one state may be unenforceable in another; disclose the fee in the signed credit application and on every invoice — a fee the customer never agreed to is uncollectible; and enforce it consistently or drop it, because selective enforcement trains customers that your terms are suggestions.

Building Block 4: Collection Triggers and the Escalation Ladder​

This is the section most policies lack: a timetable that converts "overdue" into action automatically.

Work from the aging schedule, not from memory​

Your accounts receivable aging report — current, 1–30 days past due, 31–60, 61–90, over 90 — is the dashboard for this entire section. Each bucket should have an assigned action, an owner, and a deadline. A typical ladder for a small business:

• Day 1 past due: automated friendly reminder with a copy of the invoice attached. Most first reminders collect the merely forgetful.
• Day 7–10: second notice, firmer tone, stating the due date has passed and restating the late-fee policy.
• Day 15: personal phone call from accounts receivable. Ask for a specific payment date, document it, and follow up in writing confirming what was promised.
• Day 30: formal past-due letter from a manager or owner, warning that the account will be placed on credit hold.
• Day 45–60: credit hold — no new shipments or services until the balance is current — plus a final demand letter stating a deadline before outside collection.
• Day 60–90: referral to a collection agency or attorney, or small-claims filing for balances that fit the jurisdictional limit.

Adjust the rungs to your customer base, but keep the principle: every stage is triggered by days past due, not by vibes. When the rule fires automatically, nobody has to decide whether this customer "deserves" a call — the calendar decides.

Define credit hold rules precisely​

A credit hold policy that nobody enforces is worse than none, because it teaches customers your deadlines are decorative. Specify who can place a hold (usually AR or finance, without needing sales approval), who can release one (a higher authority, and only on payment or a signed payment plan — never on a promise alone), and whether partial holds exist. The hardest moment is holding a big order from a big customer; that is exactly the moment the written rule earns its keep.

Track two numbers monthly​

Days Sales Outstanding (DSO) — average days from invoice to cash — tells you whether the policy is working in aggregate. Calculate it monthly and watch the trend: a DSO creeping from 32 to 44 days warns that terms are slipping, months before any single account looks alarming. Collection Effectiveness Index (CEI) — collected versus collectible — tells you how well the ladder itself performs. Visualizing both on a dashboard, such as the receivables views in Fava, turns a monthly chore into a glance.

Building Block 5: Paperwork That Makes It Enforceable​

A policy is only as strong as its documentation. When a dispute escalates, the business with signed paperwork wins; the business with a handshake reconstructs events from memory.

Get a personal guarantee for smaller and newer customers​

When your customer is a small corporation or LLC with few assets, the entity signature alone may be worth little if the business fails. A personal guarantee from an owner or principal makes an individual liable for the balance, which improves collectability and changes payment priority — owners pay personally guaranteed debts first. Asking for one is standard practice in trade credit, not an insult. Frame it as policy ("we require this for all accounts in their first year") and have an attorney review your guarantee language for your state.

Keep the full paper trail on every account​

For each credit sale, retain the signed credit application and terms, purchase orders, contracts or work authorizations, proof of delivery or completion, invoices, and all payment correspondence. Delivery proof deserves emphasis: signed delivery receipts or completion sign-offs defeat the most common stall tactic, the "we never received it" dispute. Store records centrally and for years, not months — commercial collection statutes of limitations run far longer than most owners expect.

Design invoices that get paid faster​

Your invoice is a collections tool disguised as a bill: clear, complete invoices get paid faster than confusing ones. Every invoice should carry an invoice number and date, a customer account number, a plain-language description of what was sold, the customer's PO or reference number, the total due prominently displayed, and the payment terms with the exact due date — including any early-payment discount deadline and late-fee notice. Send invoices the day work ships or completes; every day of delay on your side becomes a week of delay on theirs.

Five Mistakes That Gut a Good Policy​

Even businesses with a written policy undermine it in predictable ways. Watch for these:

1. Letting sales override credit. If reps can grant terms to close deals, your policy governs only the customers who never needed governing. Allow exceptions only with written finance approval.
2. Setting limits and never revisiting them. A limit approved three years ago reflects a company that may no longer exist. Calendar-driven reviews beat crisis-driven ones.
3. Chasing revenue into concentration risk. The order that doubles a customer's balance past your concentration ceiling feels like growth until it becomes a write-off. Big orders from stretched customers need deposits, guarantees, or a no.
4. Starting collections at 60 days. Recovery rates fall steeply with age; an account referred at 90 days collects at a fraction of the rate of one worked at 30. Your ladder's early rungs are the profitable ones.
5. Treating the policy as secret. Customers who never see your terms cannot follow them. Publish standard terms on your website and quotes, attach them to applications, and print them on invoices. Transparency prevents most disputes before they start.

Your One-Page Starting Template​

Draft one page covering these nine items, have it reviewed by your accountant and attorney, and start using it on the next new account:

1. Application required: no open-account terms without a signed application.
2. Approval tiers: A/B/C criteria and who approves each.
3. Starter limits: formula for new accounts and evidence required for increases.
4. Concentration ceiling: maximum share of receivables per customer.
5. Standard terms: Net terms, clock-start definition, accepted payment methods.
6. Discounts and deposits: early-pay terms offered, deposit thresholds for custom or large orders.
7. Late fees: rate, disclosure locations, consistent enforcement.
8. Collection ladder: day-triggered actions from reminder through referral, plus credit hold/release authority.
9. Review schedule: tier-based limit reviews and event triggers.

Revisit the page annually so the policy changes deliberately, in writing, instead of drifting one exception at a time.

Keep Your Receivables Visible From Day One​

A credit policy on paper only works if your books show you, every week, who owes what and how old it is getting. Clean receivables records — every invoice logged at issue, every payment applied correctly, an aging schedule you review weekly — turn the ladder from theory into routine. They also feed the two numbers that matter: your DSO trend and your allowance for doubtful accounts at year end.
