Maestro owns substitution as a demand-recovery goal, not an out-of-stock page
Substitute is a workflow Maestro owns end-to-end. When a customer's preferred product is unavailable, it reasons over brand affinity, usage, and price sensitivity to offer the alternative they'll actually want, on the stack you already run.

An empty shelf sends customers to competitors
Generic "out of stock" pages and popularity-based swaps drive customers away. Without understanding what a customer actually values, brand, size, formulation, price, every stockout is lost demand that rarely comes back.

What owning substitution means
Substitution is a goal. Maestro owns the whole thing.
Recovering a stockout isn't a 'similar items' rail. It's a business goal made of availability signals, per-customer preference reasoning, a ranked alternative, and the reason it fits. Maestro owns the goal and runs each piece per customer.
The goal Maestro owns
Turn every out-of-stock moment into a recovered sale on a product that's actually on the shelf.
In Replenit, substitution is a workflow Maestro owns end-to-end: the instant a needed product is unavailable, it reasons over each customer's preferences to offer the alternative they'll actually accept, with the reason attached.
What owning replaces
Owning the goal means owning every fragment underneath it
A legacy team hand-builds and maintains each of these separately. Maestro owns the business goal, so it runs all of them as one continuous decision, per customer.
Availability monitoring
A live read on stockouts and discontinuations across your catalog, per customer need.
Preference reasoning
Each customer's brand, format, and price tolerance, so the swap feels right.
Alternative ranking
The best in-stock option for this individual, not a popularity list.
Reason generation
The why-it-fits that makes a substitute read as hand-picked, not a fallback.
Journey timing
Delivery inside the customer's natural buying window, often triggered by replenishment.
Cross-workflow awareness
Coordination with replenishment, cross-sell, churn, and winback so the swap fits the moment.
How Maestro runs it
Detect. Reason. Recover.
Maestro runs the substitute workflow the instant a product becomes unavailable, reasoning about each customer to offer an alternative that feels hand-picked.
Availability detection
Maestro monitors availability across your catalog. When a product goes unavailable or is discontinued, the substitute workflow activates with full context.
Customer profile analysis
Using synthetic data generation, it reasons about brand affinity, usage patterns, price sensitivity, and history to find the most relevant alternative.
Serves the active workflow
It collaborates with replenishment, cross-sell, churn, and winback so the substitute lands at the right moment in the journey.
Intelligent delivery
The best alternative is delivered on your channels with reasoning that explains why it matches the customer's needs.

Olaplex No.5 Conditioner
same tierWhy Maestro wrote this
Every line is a decision, not a template
This message was composed for one customer from live memory. Nobody built a flow, wrote the copy, or picked the product — Maestro reasoned it end to end.
Triggered by a real stockout
The replenishment workflow flagged the preferred product OOS with a refill due in two days.
Matched to affinity
Strong Olaplex brand-family affinity made a same-line substitute the natural pick.
Priced within tolerance
Price sensitivity of 0.12 keeps the swap inside this customer's +/-15% comfort range.
The same decision renders to onsite, app, and SMS, each on-brand, from one reasoning pass.

Comparison
Apology pages vs. an owned workflow
The same job, run two very different ways. See what changes when Maestro owns substitution instead of a stockout owning the outcome.
Apology pages and generic alternates
When a SKU goes out of stock, most storefronts surface an apology, a 'notify me' form, or a generic 'similar items' rail driven by category. The customer with intent in their hand walks. The lost-sale moment is treated as inventory's problem, not as a recoverable revenue event.
- Apology page or generic similar-items rail
- Recovery logic ends at the cart screen
- Stockout treated as inventory loss by default
Affinity-mapped substitution
Maestro owns the whole recovery goal and treats every stockout as a decision: which alternative in your assortment does this specific customer actually want, given their brand affinity, format preference, and prior behaviour? The substitute is offered with reasoning visible, and the sale moves to a SKU that is actually on the shelf.
- Per-customer alternative ranked on affinity
- Reasoning surfaced to the shopper at the moment
- Stockout converted to a recovered sale, not lost
