Solutions / Next-best offer

Next-best-offer engine

Every customer gets a ranked list of what they are most likely to buy next, refreshed daily and delivered into the channels that actually send — email, on-site blocks, the CRM.

Who it is for

E-commerce, marketplace and subscription teams with repeat purchases and a catalogue big enough that manual curation has stopped scaling.

Short answer

A model learns from what your customers actually bought together and in sequence, and produces a ranked set of next offers per person. Stock, margin, eligibility and exclusion rules are applied on top, because the statistically best offer for an out-of-stock product is a bad offer. The result is delivered where your team already works — the ESP, the site, the CRM — and measured against whatever you rank with today.

The problem

Recommendations are the same bestsellers for everyone, and everyone has already seen them.

01

One list for the whole base

The homepage block, the email module and the CRM campaign all show the top sellers. Customers who bought them last month get shown them again, and the block earns almost nothing.

02

Manual curation does not scale

A merchandiser can maintain cross-sell rules for a hundred products, not ten thousand. So the long tail is never offered to anyone, and it quietly becomes dead stock.

03

Nobody knows if it beats bestsellers

Recommendation blocks get credit for revenue that would have happened anyway. Without a comparison against a simple popularity baseline, an expensive engine can perform worse than a sorted list.

How it works

From trigger to result, step by step.

01

Build the interaction history

Purchases, repeats, returns, browsing where you have it, and the product attributes that make items comparable. Returns matter: an offer that gets sent back is a cost, not a conversion.

02

Model, and compare against popularity

Collaborative filtering and gradient-boosted ranking are trained and then held against the honest baseline — bestsellers, and last-bought-again. We report the difference before anything ships.

03

Apply the business rules on top

Stock, margin floors, eligibility, subscription state, category exclusions and anything a regulator requires. The model proposes; your rules dispose, and the rules are visible and editable.

04

Deliver into real channels

Ranked offers land in your ESP for lifecycle emails, in on-site blocks through an API, and as fields in the CRM for the sales team. A recommendation nobody can send is a research project.

05

Hold out and measure

A share of customers keeps seeing the old logic. Revenue per customer between the two groups is the number we report monthly, and it is the number that decides whether the engine stays.

Honest limits

When this is not the right solution.

·If your catalogue is small enough for a person to curate, a merchandiser with good rules will beat a model and cost less to run.
·If customers buy once and never return, there is no next purchase to predict. The honest project there is acquisition or referral, not recommendation.
·If nothing can be measured — no holdout, no per-customer revenue view — do not build it. You will not be able to tell whether it works, and neither will we.

Questions we get about this one

Segmentation groups people; this ranks products for one person. They stack well — segments decide the campaign, the engine decides what goes in it for each recipient.

Bring us the process that hurts.

The mini-audit is free: we take your version of this process apart and tell you plainly whether automating it pays. If it does, you get a scope and a fixed price.
