About the client
This success story comes from a grocery retailer operating both physical neighborhood stores and an e-grocery platform with express delivery options. The brand is under NDA.
They launched their first company-owned store in spring 2024 and have grown dozens of locations in a major city. Their assortment emphasizes fresh and ultra-fresh products with short shelf lives (dairy, meat and fish deli, fruits and vegetables), plus pantry staples, sweets, and non-food. Over 45% of the assortment is locally produced, and the SKU count has roughly doubled since launch. Online sales were estimated at around 30% of revenue, supported through delivery aggregators and digital services.
That mix created a very specific pricing reality: fast inventory turns, frequent promo mechanics, and constant pressure to stay competitively positioned—without eroding margin on items that define the brand. The team needed a reliable way to see the market every day, not just “when someone had time,” and to make pricing and promo decisions based on comparable items—not misleading SKU-to-SKU matches that rarely exist in private label.
Their two non-negotiables:
- Analog matching (not identical SKUs) across competitors because private label dominates and direct matches are rare
- Daily competitor price monitoring inside a system the team can actually use to support pricing and promo decisions
Omnichannel Grocery RetailerNDA Protected
A fast-growing grocery retailer operating both physical neighborhood stores and an e-grocery platform with express delivery. Because their private label matching logic, promo strategies, and category margins are highly sensitive, we protect their identity under a strict Non-Disclosure Agreement. The operational workflows detailed below represent actual project outcomes.
Where it started: the pre-sales story and goals
Before partnering with PricingCraft, competitor monitoring lived in spreadsheets and screenshots. The team would open competitor mobile apps or online shelves, check a handful of “anchor” items, and log what they happened to find. It was time-consuming, irregular, and—most importantly—often not comparable.
In grocery, the “truth” changes fast. A competitor can move the effective price through a promo, a loyalty price, or a temporary out-of-stock, and you won’t see it until it’s already affecting conversion. With short-dated categories and a growing online channel, the team needed competitive context daily.
The brief
Together, we aligned on goals tied to decisions (not dashboards):
What changed after rollout
- Daily e-grocery competitor price monitoring replaced irregular manual checks: competitor pricing is now tracked once per day automatically for matched analogs, reducing dependence on ad-hoc human sampling.
- Analog matching made private label comparable: instead of searching for identical SKUs that don’t exist, comparisons are built around relevance—product type/category fit, composition/attributes, and pack size/weight.
- Weight/volume normalization improved decision quality: competitor prices are recalculated to the client’s equivalent pack size (e.g., converting a 1 kg competitor pack to a 500 g equivalent) to maintain “like-for-like” comparisons.
- Richer competitive context per item: the daily dataset includes availability, regular (“old”) price when available, current selling price, discount depth, and loyalty pricing when competitors expose it—so the team can distinguish promo effects from true price shifts.
- More complete market coverage per product: for each client item, the system prioritizes the maximum number of relevant analogs, reducing bias from relying on a single “closest” competitor item.
- Lower operational risk: the routine work of collecting, cleaning, and reconciling competitor prices moved into a controlled pipeline—freeing the team to focus on pricing actions and promo strategy instead of data gathering.
If we can’t defend the match and the unit economics behind the comparison, the data won’t be used. Our job was to co-design a system the team could trust: clear analog rules, stable daily collection, and price normalization that reflects how grocery is bought—by weight, pack, and promo mechanics.
How we achieved it: the journey from catalog to daily competitive truth
We started with a simple principle: the pricing team shouldn’t have to “fight the data” to use it. That meant sequencing the work so trust came first.
-
Step 1: We anchored everything to the client’s catalog reality
Before a single competitor price was collected, the retailer shared a structured product catalog with the attributes that actually drive comparability in grocery: SKU/internal codes, category structure, names, weight/volume and units, characteristics and composition, packaging format (including count per pack when relevant), plus images and product URLs for verification. This wasn’t bureaucracy—it was the foundation for defensible analog matching and correct unit economics.
-
Step 2: We co-designed analog rules built for private label, not wishful SKU matching
Instead of chasing exact competitor SKUs (rare for private label), we focused on repeatable comparability: same product type/category intent, composition/characteristics that impact substitutability, pack size within ±100% to keep price signals meaningful. These rules became the “constitution” for matching—clear enough for the pricing team to explain internally, and rigorous enough to scale.
-
Step 3: We operationalized matching with AI—then made it trustworthy
AI accelerated candidate discovery across competitor shelves, but we treated it as an assistant, not an oracle. A matching manager validated candidates, corrected edge cases, and fed those learnings back into the system. The result was a matching layer the team could rely on—stable enough to support daily decisions.
-
Step 4: We built resilient daily collection for e-grocery competitor price monitoring focused on business signals, not raw noise
With matching in place, the platform began daily monitoring of each “client item → competitor analogs” set. For each matched analog, we captured what pricing teams actually need: in stock / out, of stock status, regular (non-promo) price when available, current selling price, discount depth (absolute/percent where available), publicly available loyalty price when exposed. PricingCraft’s data retrieval engines were engineered for reliability and change tolerance: monitoring for page structure shifts, data validation checks, and consistent outputs—so the dataset stayed usable, day after day.
-
Step 5: We normalized prices so the comparisons stayed honest
Grocery pricing breaks the moment pack sizes differ. So we normalized competitor prices to the client’s equivalent weight/volume. When competitors didn’t provide weight as a clean field, we scraped it from the product name, validated it, and then computed comparable price points. This preserved “like-for-like” comparisons and kept category-level indexes meaningful.
-
Step 6: We embedded the output into the team’s decision cadence
Finally, we made sure the data landed where it could drive action—via dashboard views and export/API delivery patterns that fit the team’s workflow. The goal wasn’t to create “more data.” It was to create a daily market signal the team could use to protect positioning, interpret promo moves, and respond faster.
Inside the Output: Analog Matches & Normalized Prices
An anonymized look inside the PricingCraft dashboard. The pricing team can instantly review AI-assisted analog matches for private label items, compare weight-normalized prices (e.g., recalculated to a 1kg equivalent), and break down regular versus promotional pricing—all refreshed daily.
Challenges we hit-and how we solved them
The methodological challenge: defining “what counts as an analog” for private label
Because private label represented a significant share of the assortment, direct matches were rare—and “analog” can be subjective. The early risk was inconsistency: one person’s “match” could be another person’s “too distant substitute,” especially in edge cases around ingredients, format, or pack size.
How we addressed it (in partnership):
- We aligned with the client team on analog rules and walked through borderline examples together
- We formalized matching criteria: product type/category fit, composition/attributes, and weight within ±100% of the client item
- We documented the rules clearly so matching could scale without reinventing decisions each time
Resolution: Documented analog matching rules
The technical challenge: analog matching required tuning AI precision
Initial matching was automated, but early iterations could misclassify atypical items or confuse similar products with different characteristics. We needed stable quality before expanding coverage.
How we addressed it (in partnership):
- We used an AI + manual validation loop: AI produced candidates; a matching manager reviewed and corrected
- We iteratively tuned the model using feedback until matching quality became consistent
- After the “training” period, the workflow became predictable and no longer required constant hands-on intervention
Resolution: AI + Human-in-the-loop validation
Competitor data gaps: weight wasn’t always a structured attribute-and normalization depended on it
To compare prices correctly, competitor prices had to be normalized to the client’s pack size. But some competitor listings didn’t provide weight/volume as a clean attribute; it lived in the product title.
How we addressed it (in partnership):
- Our engineers implemented logic to scrape weight/volume from competitor product names when it wasn’t available as a separate field
- Managers manually validated extracted weights to prevent silent errors
- Validated weights then powered consistent price normalization—keeping comparisons in identical units
Resolution: Algorithmic weight extraction
Two e-grocery competitor price tracking lessons that held up in the real world
Lesson 01
Private label monitoring only works if analog matching is explainable
In grocery, “close enough” isn’t close enough unless the team can defend why the match is comparable. Clear rules (category intent + composition + pack size bounds) beat black-box matching every time-especially when stakeholders challenge pricing decisions.
Lesson 02
Promo mechanics can hide real price moves unless you capture context
A competitor’s “price” isn’t a single number. Without in-stock signals, regular vs promo price, discount depth, and loyalty pricing (when available), teams end up reacting to noise. Capturing context turns daily e-grocery competitor price tracking into decision support instead of an alert feed.
