On time in full
OTIF meaning: what on time in full measures, and how to calculate it
OTIF is one of those measures everyone in trade agrees on until the moment someone has to calculate it. Two people can read the same week of deliveries and report 71% and 94%, both correctly, because they counted different things. This is what the measure says, how it is calculated, and where the number goes wrong.
What the letters stand for
OTIF is on time in full. A delivery counts when it arrives by the agreed date and in the quantity that was ordered. Both conditions at once, on the same delivery.
That word “both” is the whole measure. A delivery that came on the promised day, short by two cases, does not count. A delivery that came complete, four days late, does not count either. OTIF is not the average of a punctuality score and a completeness score. It is the share of orders where nothing went wrong on either axis.
Which is why OTIF never comes out higher than the punctuality and completeness figures quoted before anyone starts measuring, and usually comes out well below both. Deliveries tend to be late or short, rarely both, so each separate score looks respectable while the combined one does not.
How OTIF is calculated
Divide the number of orders that arrived on time and complete by the total number of orders in the period. The formula takes one line. The decisions around it are what produce different answers.
The level you count on
An order has lines. If one line out of twelve came short, did the order fail, or did that line fail? Both readings are legitimate. Counting on whole orders answers how often the customer got everything they asked for. Counting on lines answers how much of what was promised actually moved. The same week gives two different percentages, and both are worth keeping, because they describe different parts of the same problem.
What counts as delivered
In full is binary at both levels: 90% of the quantity on a line is not 90% of a point, it is zero. Teams coming from a proportional metric find this brutal at first, and it is the reason the measure is useful. Partial delivery is not partial success for the store with an empty shelf.
The third reading
Many manufacturers also keep a proportional view next to OTIF: quantity delivered divided by quantity ordered, where 80 cases out of 100 count as 80%. That reading sits closer to fill rate than to OTIF, and it answers a different question: how much of the promise held, rather than whether it held.
Where the clock starts and stops
On time is the half people argue about, and almost always for the same reason: two partners are measuring from different moments.
The start can be the moment the rep took the order, the moment it reached the distributor, or the moment the distributor confirmed it. The end can be the date on the delivery note, the date the goods were booked in, or the date the invoice was issued. Pick different ends and the same delivery moves by two or three days.
The rule that matters is not which convention you choose. It is that one convention applies to every partner. The moment two distributors are measured differently, the ranking in the report means nothing, and everyone in the room knows it.
That is how OTIF reviews turn into arguments about the data instead of conversations about the deliveries.
OTIF and fill rate are not the same number
The two get used as if they were interchangeable. They are not, and the difference is useful.
| Fill rate | OTIF | |
|---|---|---|
| What it counts | how much of the quantity arrived | whether the order arrived complete and on time |
| How it counts | proportionally: 80 of 100 cases is 80% | binary: an incomplete delivery counts as nothing |
| What it misses | timing, entirely | the size of the gap when something is missing |
| What it is good for | sizing the shortfall | holding a delivery standard |
Read together they separate two causes. Stock that was not there pulls the proportional number down and takes OTIF with it. A truck that left two days late leaves the proportional number untouched and fails OTIF on its own. One figure tells you how much is missing, the other tells you whether the promise held.
What counts as a good OTIF level
The honest answer is that the benchmark worth watching is your own trend, because the level depends on the channel, the category and what the agreement says. A chilled product delivered daily and a promotional multipack built for one campaign do not belong on the same scale.
Two things hold across the manufacturers we work with. The first measurement is usually lower than people expect, and that is a property of the measure rather than a verdict on the partner. And the level moves once results are reviewed with distributors every month instead of reported internally. In our deployments, in-full delivery reached up to 95% once the measurement was running and the results were on the table at every review. That figure is the in-full half on its own. OTIF, with the date counted as well, sits lower on the same data.
The level matters less than knowing which partner, which branch and which product sits under it.
When the delivery is not yours
Everything above assumes you control the delivery. In FMCG sold through distributors, you do not.
The rep takes the order in the store. The order goes to the distributor who serves that store. The distributor picks, ships and invoices. The manufacturer sees the order its rep took and passed on, and the sales figure that comes back, and between those two numbers sits every case that never reached the shelf.
This changes three things about measuring OTIF.
The data is not yours to begin with
Evidence of what was delivered sits in the sales documents the distributor issues when goods leave its warehouse, delivery notes and invoices alike, not in your own records. Measuring starts with getting those documents back in a readable form, matched to the orders they cover, in your own product and customer codes.
The date convention has to be agreed, not assumed
With your own fleet you can define the clock. With twenty distributors you have to agree it and write it into the agreement, or every review starts with a dispute about which day counts.
The measure becomes a shared standard rather than an internal report
Once both sides accept the same in-full figure, calculated from documents the distributor itself issued, a delivery standard can sit in the agreement next to volume targets, with a bonus attached to it. That is a different conversation from asking a partner to improve. It is the case the OTIF module in Trade Terms & Settlement was built for.
Three ways the number goes wrong
Mixing levels in one report
Whole orders on one slide, lines on the next, and a trend that moves for no reason anyone can name. Keep both readings, label both, and never average them.
Counting from the invoice date
The invoice is issued when the distributor is ready to issue it, which is not when the goods arrived. It is the easiest date to get and the one that quietly flatters the result.
Removing orders after the fact
Cancelled lines, quantity corrections agreed by phone, emergency orders that were never meant to be complete. Each exclusion is defensible on its own, and together they turn the measure into a description of the deliveries you chose to count.

Andrzej runs sales and delivery for Trade Data Hub and Trade Terms & Settlement. Measuring OTIF through distributors is the layer he works in: the documents, the date conventions and the commercial terms between a producer and the partners who deliver for it.
If you are setting this measurement up, or arguing about the number with a partner, that is the conversation to have.
Frequently asked questions
Is OTIF the same as DIFOT?
In practice, yes. DIFOT stands for delivered in full, on time, and it measures the same two conditions in the other order. Some companies use DIFOT for what the customer received and OTIF for what the supplier shipped, so where both terms are in use inside one organisation, it is worth writing down which one is measured on which document.
Who owns OTIF in a company that sells through distributors?
It sits between two roles, which is why it often sits nowhere. Supply chain owns availability, sales owns the relationship with the distributor, and a delivery that failed is usually a mix of both. The measurement works when one report serves both sides, broken down by distributor for the commercial conversation and by product for the supply one.
Can OTIF be measured when the distributor delivers, not the manufacturer?
Yes, and it is measured on documents rather than on operations. The orders a field team places with distributors are matched against the sales documents the distributor issues when goods leave its warehouse. The comparison runs order by order and line by line, which is also what makes the result usable in a distributor agreement.
