Most MSPs build the service, then figure out the payment terms on the handshake. Then month three arrives, and your best client pushes payment 15 days. Month five, they’re 45 days late. You’re carrying their cash flow, they think it’s normal, and you’re both pretending the elephant in the room isn’t there.
A late payment policy isn’t hostile. It’s clarity. It says “here’s how we handle cash flow” the same way your SLA says “here’s our uptime commitment.” Clients who can’t live with your terms were never going to be predictable payers anyway.
This template covers the parts that matter: what happens when payment is late, how much lateness you’ll absorb, what triggers escalation, and what service pause looks like without terminating the relationship.
When a late payment policy makes sense
Use this template when:
- You manage recurring services (managed IT, security monitoring, backup, cloud infrastructure, phone systems).
- Your contracts don’t specify what happens after the due date passes.
- You’ve had 3+ clients drift 15-30 days late and you want to set expectations upfront.
- You need cash flow predictability but don’t want to be the “difficult vendor.”
This template is NOT for one-off projects (those need a different structure) and NOT for clients who’ve already proven reliable (sometimes the relationship earns you flexibility). But for new clients and your baseline terms, this gives you language.
The policy template
MSP LATE PAYMENT POLICY Effective Date: [today] Updated: [date if revised] PAYMENT TERMS Standard payment terms are Net [15/30/45], meaning payment is due within [15/30/45] days of invoice date. Invoices are due on the date specified unless otherwise noted in your service agreement. Invoices may be paid by [check, ACH, credit card, automatic recurring charge from your configured payment method]. DUE DATE DEFINITION A payment is considered received on the date funds clear into our account, not the date you mail or submit the payment. For credit card or ACH payments, the due date is the calendar due date; we do not grant grace periods for processing time. LATE PAYMENT: DAYS 1-15 OVERDUE If an invoice remains unpaid 1-15 days after the due date: 1. We will send a courtesy reminder (email or phone call, at your primary contact's preference). 2. We assume payment is in progress or there's a processing issue. 3. No service changes. No late fees. 4. No impact to your account status. This is the "it slipped" window. We expect payment within 5 business days of the reminder. If payment doesn't arrive, see the next section. LATE PAYMENT: DAYS 16-30 OVERDUE If an invoice is 16-30 days overdue: 1. We will send a formal notice (email to your primary contact and finance contact if on file). 2. The notice outlines the outstanding balance, due date, and the next steps if payment doesn't arrive within 5 business days. 3. No service suspension yet. Your services continue uninterrupted. 4. Late fees begin: [1.5% per month or $[X] per invoice, whichever your state allows] applied to the next invoice if this one isn't paid within 5 business days. At this stage, we assume there's a cash-flow problem or a processing error. The formal notice usually resolves it. LATE PAYMENT: DAYS 31-45 OVERDUE If an invoice is 31-45 days overdue: 1. We send a second formal notice offering three options: - Pay in full by [specific date, 5 business days out] - Propose a payment plan (see "Payment Plans" section below) - Arrange a call to discuss any underlying issue 2. Late fees continue to accrue if the original invoice is unpaid. 3. Service changes may begin (see "Service Pause" section below). We will notify you 48 hours before any service change takes effect. LATE PAYMENT: DAYS 45+ OVERDUE If payment is 45+ days overdue and we've received no response to two formal notices: 1. We schedule a call with your decision-maker (your manager, owner, or finance lead). 2. On that call, we discuss either (a) a structured payment plan, (b) an immediate catch-up payment with a plan for future invoices, or (c) transition of services if the business relationship isn't sustainable. 3. Service pause or suspension may take effect if no agreement is reached within 48 hours of the call. PAYMENT PLANS If you can't pay in full on the due date, ask for a payment plan. We prefer 50% now and 50% in 14 days for invoices 30+ days overdue, or a three-payment split for larger amounts. To request a payment plan: 1. Contact your account manager with the proposed schedule. 2. We'll confirm acceptance via email. 3. The plan becomes binding once both parties confirm. Missing a planned payment puts you in the Days 31-45 or 45+ bucket above. Payment plans are a one-time accommodation. A second late payment does not automatically get another plan. SERVICE PAUSE (NOT TERMINATION) If payment is 45+ days overdue and we haven't received a response to formal notices, we will pause non-critical services to create pressure without breaking your business. Specifically, we will pause or throttle: - Backup and disaster-recovery scheduling (you retain access to archives; new backups pause) - Proactive monitoring and alerting - Non-critical patch scheduling - Routine maintenance tasks We will NOT pause or suspend: - Active remote-access sessions if you're in an incident - Critical system access - Phones or email if those are your primary services (unless those are explicitly in scope for late-payment service pause in your signed agreement) The pause is a lever, not a termination. If payment arrives, the pause lifts immediately and full services resume the next business day. Service pause requires [2 business days] notice before taking effect. You'll receive written notice specifying which services pause and when. DISPUTING AN INVOICE If you believe an invoice is incorrect: 1. Contact your account manager or finance contact within 14 days of the invoice date. 2. We'll review the charges and either confirm them or issue a credit. 3. The portion of the invoice you dispute does not need to be paid while we review it. However, undisputed portions are still due on the standard due date. 4. If we confirm the charges are correct, the full invoice becomes due immediately. Disputing an invoice does not pause the clock on our late-payment policy. If the full invoice (minus agreed-upon adjustments) goes unpaid 30+ days after the original due date, the escalation process above applies. LATE FEES Late fees are charged at [1.5% per month / $X per day / your state's legal maximum], whichever applies in your state. Late fees are added to the next invoice or billed separately if the original invoice is fully paid. Late fees accrue only if the invoice remains unpaid more than [15 days] past the due date. CREDIT CARD PROCESSING DELAYS If you pay by credit card, we process within [1-2 business days]. We do not extend the due date for processing delays. To avoid late fees, submit your card payment 2-3 business days before the due date. If you have recurring services billed to a card, ensure your card has sufficient balance and is not expired. A declined card counts as a missed payment for the purposes of this policy. CHANGES TO THIS POLICY We may update this policy with [30 days] notice. Changes apply to invoices dated on or after the effective date. Existing service agreements retain their original terms unless you request an update. Changes to this policy will be sent to your primary contact and posted to your account portal.
How to implement this with your clients
New clients: Include this policy in your standard service agreement or send it with the first invoice. Make it clear: “This is our standard payment policy. It’s not personal; it applies to everyone.”
Existing clients: Send it 30 days before the effective date with a brief cover note: “Starting [date], we’re standardizing our payment terms across all clients. This policy applies going forward and sets expectations upfront.” Most will accept it without pushback if they’ve been paying on time.
Clients with a history of late payment: Have a direct conversation. “You’ve been valuable, but the 30-day gaps are tight for our cash flow. We need to set clearer terms. This is our policy for everyone going forward.”
Key mechanics in this template
Days 1-15: You absorb small delays. This is goodwill, and it covers legitimate processing time.
Days 16-30: Late fees kick in and formal notices start. You’re signaling this isn’t drifting.
Days 31-45: You escalate to conversation and introduce the payment-plan option. Most cash-flow problems resolve here.
Days 45+: Service pause takes effect. Pause is not termination, but it makes the stakes clear.
The point of this structure is preservation. You’re not trying to anger clients or end relationships. You’re trying to protect cash flow while giving them three chances to fix it (reminder, formal notice, conversation, payment plan). Most will land in one of the first three.
Why “pause” instead of “suspend”?
Full service termination is scorched earth. You lose the client forever and you spent months carrying their debt. A pause (backup scheduling stops, proactive monitoring pauses, patches get delayed 2-3 days) sends a message without destroying the relationship. Many clients will call within 48 hours of a pause with payment.
If they don’t, you have clearer justification for full termination because you’ve tried everything else.
Next steps: collections when pause isn’t enough
If 45+ days passes, the pause isn’t working, and the client still hasn’t paid or scheduled a call, you’ve moved past what an internal policy can fix. This is when you escalate to formal recovery, either through an external collection agency or (if the amount justifies it) through formal legal demand.
For structured recovery that sits between pause and external escalation, see the guide to MSP retainer enforcement without losing clients for escalation sequences that preserve some relationship while making clear the debt is serious.
ti3 can automate this escalation sequence for you, handling the reminders, formal notices, and payment-plan offers in your name so you don’t have to carry the emotional labor. See how it works at /for/msps/.
FAQ
Can we charge interest on late invoices in our state?
Yes, if your state allows it. Most states set a legal maximum (typically 1.5% to 3% per month). Check your state’s statutes or consult a local business attorney. The template above includes a placeholder for interest if your state permits it.
What if a client disputes the invoice after it’s 45+ days late?
Address the dispute on its merits (is the charge correct?), but don’t let it pause the escalation clock. A 45+ day unpaid invoice + a dispute = still a 45+ day invoice that needs resolution. Handle them in parallel: investigate the dispute and, if it’s valid, issue a credit; if it’s not, confirm the charge and move forward with payment or service pause.
Do we have to pause non-critical services, or can we go straight to termination?
Your policy, your choice. Some MSPs build in a pause stage (less destructive). Some go straight to full termination at day 45+. This template gives you the pause option because it gives clients one more chance to fix it. But if your cash flow can’t absorb the delay, or if you’ve been burned before, you can remove the pause stage and go straight to termination language.
What if we’re an MSP with a phone system as the primary service? Can we pause the phone system?
Probably not. A pause on phones is a pause on the client’s business, which is different from pausing backups or proactive monitoring. Build phone services into the “do not pause” category. If a phone-system MSP needs leverage on day 45+, the alternative is full termination or a structured payment plan. You can’t do a middle ground there.
What happens after service pause if the client finally pays?
Services resume immediately. Send a brief confirmation: “Payment received. All services are now live and scheduled to resume full functionality by [next morning].” Paste the resume process into your support ticket so it’s automatic, not a manual step you forget.
