For couriers, a delivery SLA sets the standard each delivery has to meet for an enterprise client, such as arriving within an agreed window with the right proof of delivery. Meeting that standard consistently is a big part of keeping the account, but that depends on two things. You need to measure and prove each delivery against the SLA, and you need to see a delivery running late early enough to fix it before it misses its window.
Many couriers review SLA performance in a monthly report. By the time that report shows a late delivery or a missing signature, the client has usually noticed it already. In healthcare, the stakes are higher, because a missing delivery record can count as a breach even when the delivery itself arrived on time.
This article covers how to define, track, and report delivery SLAs so they hold up with enterprise clients, and what to do when you miss one.
Quick answer: How do couriers meet delivery SLAs for enterprise clients?
- Define SLA terms your data can measure. Agree on the delivery window, when the clock starts, which failed deliveries count, and what proof each delivery needs, then check that your delivery system records each one. Commit only to an on-time rate your own data shows you can hit.
- Catch late deliveries and missing proof early. Track each delivery against its SLA window so dispatch can reroute or reassign a late one in time. Make drivers capture the required proof before they can complete a delivery.
- Report from your delivery records. Build SLA reports from the same data your team works from, and give each enterprise client a client portal where they can see their deliveries, proof of delivery, and reports themselves.
- Use the data when you miss. A delivery's record shows whether a miss was outside your control or what caused it, such as one driver who's often late, so you can explain it to the client and fix it.
How to Define Delivery SLAs You Can Measure and Prove
Enterprise clients usually come to a courier with SLA terms already in mind, based on the service they've promised their own customers. Before you sign, the question for your team is whether your delivery data can measure each term the way the contract defines it, and prove it for any order the client picks.
The table below covers terms most enterprise SLAs include. Your clients may add others, so treat it as a starting point.
Make sure "on time" means the same thing in the contract and in your data
Two parts of the on-time definition cause most mismatches. The first is when the clock starts. If it starts when the client creates the order, but your driver can only pick it up once it's packed, any delay on the client's side counts against you.
The second is which moment counts as delivered: the driver arriving, the driver marking the delivery complete, or the recipient signing. Each can carry a different timestamp. Agree on both in writing, then check that your delivery system records that exact moment for each delivery.
Agree on which failed deliveries count against you
Some failed deliveries are outside your control, such as a closed facility, a refused delivery, or a wrong address. Most enterprise contracts can exclude them, but only when the driver records the reason, with a note or photo, at the time of the attempt. Without that record, the client can't tell those failures apart from the ones your team caused.
Treat proof of delivery as part of the SLA
For pharmacy and medical delivery clients, a delivery without the right proof often doesn't count as delivered. The contract should list the proof each delivery type needs, such as a signature with the signer's name, a photo, a barcode scan, or a PIN. Controlled substances and lab specimens often need a full chain of custody too.
Agree on how quickly records reach the client after each delivery. Healthcare clients and their auditors may ask for the proof behind specific orders weeks later.
Check your own numbers before you commit
Before you agree to an on-time rate, pull your own performance for similar routes and volumes, including your busiest weeks. Commit to a rate your data shows you hit consistently, and have your legal team review the remedies, such as service credits, that apply when you don't. SLA terms you can measure and prove also make it easier to win larger pharmacy delivery contracts.
How to Track Delivery SLAs and Catch Late Deliveries Early
A delivery usually starts to slip well before it misses its window. A route runs long, a stop takes more time than planned, or a driver calls in sick. If your team sees it early, they can still fix it. If they first see it in the monthly report, the client already has.
Track each delivery against its SLA window
Give every order its SLA window in your delivery system, so its status is measured against the contract and not only against the route plan. A driver can be on schedule for the route and still be on track to miss one facility's window.
When a delivery starts running late, dispatch can re-sequence the route or move the stop to another driver. Each of those fixes only works if the delay shows up early.
What to look for: Route optimization that plans around delivery windows, predictive ETAs that update as drivers move, and delay alerts that flag at-risk deliveries before the window closes.
Capture proof at the door, not after the route
Proof that arrives later, on paper or by text message, leaves gaps your client may find before you do. The most reliable approach is to make the required proof part of completing the delivery, so a driver can't close it until each step is captured.
This matters most when new or fill-in drivers cover a route. They don't yet know each client's requirements, so missing proof tends to cluster around drivers who are still ramping up.
What to look for: A driver app that enforces required proof of delivery steps by delivery type, with photos stamped with the time and location.
How to Report Delivery SLAs to Enterprise Clients
SLA reporting is where your numbers and the client's meet. When both sides look at the same delivery records, most disagreements about the numbers go away, and a miss becomes something you can explain and fix.
Report from the records your team works from
Build the SLA report from the same delivery records your dispatchers use every day. Most enterprise clients look for:
- On-time rate against each agreed window, by location
- Failed deliveries, with the reason recorded at each attempt
- Excluded deliveries, with the evidence behind each one
- The share of deliveries with every required proof captured
Clients shouldn't have to wait for the monthly report to see how you're doing. When they can check their own deliveries and data at any time, they can answer their own questions, such as whether an order arrived on time or where its proof of delivery is, without calling your team.
What to look for: A client portal you can set up for each enterprise client, where they can track their deliveries in real time and pull proof of delivery, delivery history, and reports whenever they need them, including during an audit.
Use delivery data to understand and fix a miss
When a delivery misses its SLA, granular delivery data shows what happened, whether you're checking from your side or the client is checking theirs. The record for each delivery shows when it was completed, where the driver was, what proof was captured, and any failure reason the driver logged. That record helps you:
- Check whether the miss is justified. If the facility was closed or the client released the order late, the miss may fall under an agreed exclusion, and you have the evidence to show it.
- Find the cause when it's on your side. If one driver is behind most of the late deliveries, the issue is with that driver, not your whole operation. If misses cluster on one route or at one location, the route may have too many stops for its window, or drivers may be waiting too long at receiving.
- Fix it before it becomes a pattern. Breaking performance down by location, team, and driver shows you exactly what to change.
- Build trust with the client. You can explain what happened, show the data behind it, and tell them how you're fixing it. A clear answer backed by evidence carries weight when the contract comes up for renewal.
How Onfleet Helps Couriers Measure, Prove, and Hold Delivery SLAs
Onfleet is a last mile delivery platform that helps couriers run their own drivers efficiently and prove each delivery to the enterprise clients they serve. For couriers with enterprise SLAs, that means catching late deliveries before they become misses, and giving clients proof they can check themselves.
- Routes planned to meet each SLA window. AI-enhanced route optimization builds routes so each stop lands inside its agreed delivery window, which is where on-time SLAs are met or missed. When an urgent order like a STAT comes in, on-demand dispatching adds it to a route already on the road, so you can meet its window without sending out an extra driver.
- Early warning on late deliveries. Predictive ETAs and delay alerts flag deliveries at risk of missing their window while dispatch can still act. Geofencing works alongside predictive ETAs to reduce failed and missed deliveries.
- Proof captured at the door. You choose which proof of delivery steps each delivery requires, such as a signature, photo, barcode scan, or PIN. The driver app won't let a driver complete the delivery until each step is captured, and chain of custody is recorded along the way.
- Performance by location, team, and driver. Analytics dashboards give you a live view of how each location, team, and driver is performing, so you can spot what's behind a miss without manual reporting. Clients can check the numbers themselves anytime, without waiting for a month-end report.
- Visibility for your clients. Branded SMS updates and live tracking pages tell recipients when to expect their delivery, so someone is ready to receive it and fewer attempts fail. They also cut "where's my delivery?" calls to your client, and from your client to you.
How ABD Transportation won bigger pharmacy contracts with Onfleet
ABD Transportation is a pharmaceutical courier delivering prescription medications, narcotics, and cold-chain treatments across the Greater Toronto Area. When it started going after larger pharmacy contracts, ABD ran on Excel and a separate routing app, and clients had no real-time visibility into their deliveries. A large pharmacy prospect liked ABD's model but wouldn't sign without a proper platform. It needed delivery records that were documented and easy to access in an audit.
After moving to Onfleet, ABD signed two new large pharmacy clients in less than a year. Automated notifications and live tracking give patients a one-hour delivery window, which cut failed deliveries from 22 to 4 a day. "Where is my order" calls dropped from 8 to 10 a day to almost none. When pharmacy clients face an audit, they now pull their delivery data themselves through Onfleet's client portal.
"With Onfleet, it's easier to access the data. That's actually what made us switch." Abdul Daas, CEO, ABD Transportation

Frequently Asked Questions About Delivery SLAs for Enterprise Clients
How can couriers make sure drivers capture the right proof of delivery?
Couriers can make sure drivers capture the right proof of delivery by making it part of completing each delivery, so drivers don't have to remember each client's requirements. With Onfleet, couriers set the required proof of delivery steps for each type of delivery, such as a signature, photo, barcode scan, or PIN. The driver app won't let a driver complete the delivery until each step is captured, and photos are stamped with the time and GPS location.
How can couriers reduce failed deliveries?
Couriers can reduce failed deliveries by telling recipients when to expect their delivery, since many attempts fail because nobody is there to receive it. Onfleet sends recipients branded SMS updates and a live tracking link, so they know when the driver is coming. Pharmaceutical courier ABD Transportation gives patients a one-hour delivery window this way, which cut its failed deliveries from 22 to 4 a day.
How can couriers track SLA performance in real time?
Couriers can track SLA performance in real time by giving each order its SLA window in their delivery system, with ETAs that update as drivers move and alerts when a delivery is at risk of running late. That lets dispatch re-sequence a route or reassign a stop before the window closes. Onfleet provides predictive ETAs and delay alerts, and its open API and webhooks can send delivery updates into a client's own systems as they happen.
How can couriers give enterprise clients visibility into their deliveries?
Couriers can give enterprise clients visibility by giving them their own access to delivery information, so clients don't have to call dispatch or wait for a monthly report. Onfleet's Courier Suite includes a client portal that couriers set up for each client. Clients log in to track their deliveries in real time and pull proof of delivery, delivery history, and reporting whenever they need it. Pharmaceutical courier ABD Transportation says its pharmacy clients use the portal to pull their own delivery data when they face an audit.
How are delivery SLAs different for healthcare couriers?
Delivery SLAs for healthcare couriers usually make proof of delivery a requirement in its own right. A delivery that arrives on time without a required signature, scan, or chain of custody record can still count as a breach, and auditors may ask for the proof behind specific orders. Onfleet lets healthcare couriers require proof of delivery steps by delivery type, records chain of custody, supports HIPAA compliance with a signed BAA, and is SOC 2 Type 2 audited.
