Estimato — Delivery Date ETA Widget for Shopify (Built for Shopify)
A Built for Shopify certified app that adds an estimated-delivery-date widget to product pages. Merchants define processing and shipping times as rules scoped by country, region, product, collection or location, apply them via reusable templates, and style the widget to match the theme — all no-code. The storefront widget renders a dated arrival estimate with an order-placed / shipped / delivered timeline. Free tier for a single rule; $4.99/month (or $44.91/year) for unlimited rules, all templates and storefront multi-language across seven locales. Launched 30 June 2021.

The brief
The challenge, and how we approached it
01
The challenge
"When will it arrive?" is the last unanswered question before add-to-cart, and it drives both abandonment and support tickets. But the answer isn't one number — it varies by product, fulfilment location and destination country, and no merchant will maintain that matrix by hand or hire a developer to render it.
02
Our approach
Model delivery time as composable rules rather than a static message: processing and shipping times set independently, scoped by country, product, collection or location, then bundled into reusable templates that apply across the catalogue. The storefront widget presents the result as a dated arrival estimate with a three-stage progress timeline, not a vague range — concrete enough to reduce pre-purchase questions. Appearance is fully themeable through a settings panel with template presets, so it reads as native rather than bolted on. Storefront copy localises across seven languages for international stores. The free tier allows one rule, which is enough to prove the widget converts before paying $4.99. Built to Shopify's performance, design and integration standards — the listing carries Built for Shopify certification.
What we built
Six capabilities shipped for Dana's Bakery
Each one solves a specific part of the brief above.
ZIP-gated shipping
Real-time validation prevents invalid ZIP purchases from entering cart
Drop architecture
Pre-staged inventory with countdown, sold-out gates, and waitlist
Gifting flow
Message cards, recipient addressing, scheduled delivery, gift wrap
Perishable inventory
Daily inventory sync with cold-chain capacity constraints
Drop-day performance
Theme architecture handles 20× traffic spikes without latency
Recurring orders
Holiday subscription flow for repeat gifters
How it ran
10 weeks build, in four stages
Every engagement runs the same four stages, so you always know what happens next and what you owe us at each one.
Stage 1
Audit and scope
We review the current theme, apps and analytics, then write a fixed-scope SOW with named deliverables and a date.
Stage 2
Design and build
Work happens in a dev store on a Git-backed workflow. You get a preview link from week one, not a reveal at the end.
Stage 3
QA and launch
Cross-browser and device QA, redirect map, analytics verification, then a launch window agreed with you rather than dropped on you.
Stage 4
Hypercare
Fourteen to sixty days of included post-launch support while real traffic finds the edge cases.
The outcome
Where Dana's Bakery landed
Conversion is up 2.1× after the PDP rebuild, AOV is up 34% year-over-year thanks to gifting upsells, and drop days are now smooth — zero downtime across 12 drops in the past year.
