How to Calculate Your Pet Store's Customer Reorder Cycle (And Why It Matters)
Your POS system is sitting on a gold mine of data you are probably not using. Every transaction tells a story. And if you know how to read that story, you can predict exactly when a customer is about to stop coming in and reach them before they switch to Chewy.
The secret is something called the customer reorder cycle. It is the single most important number in your business that you are probably not tracking.
What Is a Reorder Cycle?
A reorder cycle is the average number of days between a customer's repeat purchases for the same type of product. If Sarah buys a bag of dog food on January 3rd and comes back for another on February 12th, that gap is 40 days. If she comes back again on March 28th, that gap is 44 days. Her average reorder cycle is 42 days.
That number is gold. Because once you know Sarah's cycle is 42 days, you know something incredibly powerful: if day 49 rolls around and she has not come in, something is wrong. She is overdue. She may have ordered online. And every day that passes without a visit makes it less likely she is coming back.
How to Calculate It Yourself
You do not need fancy software to figure this out. Here is a simple method you can do with your POS data and a spreadsheet in about 30 minutes.
- 1
Pick your top 20 customers. Sort by total spend or visit frequency over the last 12 months. These are the customers who matter most to your revenue.
- 2
Pull their last 3 to 4 purchase dates for the same product category. Focus on food purchases first since those are the most predictable and highest value.
- 3
Calculate the gap between each purchase in days. January 3 to February 12 is 40 days. February 12 to March 28 is 44 days.
- 4
Average those gaps. That is the customer's reorder cycle. In this example, 40 plus 44 divided by 2 equals a 42-day cycle.
- 5
Compare their last purchase date to today. If it has been longer than their average cycle, they are overdue. The further past their cycle, the higher the risk they have already switched.
Common Reorder Cycles for Pet Products
Every customer is different, but here are typical ranges to help you benchmark. If a customer is significantly past these windows, they may have already found another source.
| Product Category | Typical Reorder Cycle |
|---|---|
| Dry dog food (25-30 lb bag) | 35 - 45 days |
| Dry cat food (10-15 lb bag) | 28 - 38 days |
| Cat litter (25-30 lb) | 21 - 30 days |
| Treats | 14 - 28 days |
| Flea/tick prevention | 28 - 35 days |
| Supplements | 25 - 35 days |
What to Do With This Information
Knowing the reorder cycle is only useful if you act on it. Here is a simple framework for turning this data into recovered revenue.
7+ days past their cycle: Overdue
Send a friendly reminder. A quick text or email that says "Hey, it has been a while since your last visit. Need us to set aside your usual order?" This is the sweet spot where a gentle nudge can bring them back before they start shopping online.
15+ days past their cycle: At Risk
This customer may have already placed an online order. A stronger outreach is needed. Consider a small incentive like 10 percent off their next visit or a free sample of something new. Make coming back feel easy and rewarding.
45+ days past their cycle: Likely Gone
At this point, they have probably set up a recurring order somewhere else. Send a win-back offer. Something meaningful enough to break the inertia of auto-ship. A personal note from the owner, a significant discount, or an invitation to an in-store event can sometimes bring back even the most lapsed customers.
The Simple Version
If all of this feels like a lot, here is the core idea in one sentence: Know when each customer should come back. Notice when they do not. Reach out before Chewy does.
That is it. That is the entire strategy. The stores that track reorder cycles and act on overdue customers keep their revenue. The stores that wait for customers to walk back in on their own lose them to auto-ship one by one.
You do not need to track every customer manually forever. Even doing this exercise once with your top 20 accounts will show you exactly how many overdue customers you have right now and where your revenue is leaking.
