Technology Partnership Proposal · Prepared for Corda.

The platform beneath the brand.

Corda has a clear brand vision and a considered product. This proposal is about everything customers never see: the commerce platform and the connected systems that make an elevated D2C furniture brand run quietly, reliably, and at scale.

EngagementBuild & integration partner
Considered minimal interior

Considered, elevated, and built to last. The platform should feel the same.

01 Understanding the brief

We read the whole brief, not just the website.

Most developers will quote you a Shopify theme. Your brief asks for something materially harder: a connected operation. Three order types, In-Stock, Made-to-Order and Backorder, each flowing cleanly through inventory, fulfilment, freight, support, reviews and accounting, with the right message reaching the customer at every step.

That is the real project. The storefront is the visible tenth of it. The other nine tenths is the integration architecture you've mapped out, and getting that architecture right is the difference between a brand that scales calmly and one that drowns in manual workarounds six weeks after launch.

This proposal is structured around that reality. It is honest about what is achievable by Boxing Day, deliberate about what should wait, and clear about where the genuine technical risk sits, so you can make a confident decision about who you partner with.

02 How we think about it

Three principles that
shape the build.

i.

Launch lean, scale deliberately

Every system you've listed is sound. Not all of it needs to exist on day one. We sequence the build so you launch on time with what matters, and add operational automation as order volume justifies the cost and complexity.

ii.

Own everything we build

Documented integration logic, a system map, and credentials handed to you. No lock-in, no black boxes. You asked to own your technology in the same detail you document your business. That is exactly how we work.

iii.

De-risk the hard part first

The inventory and order-routing layer is the riskiest piece of this build. We prove it in a sandbox before a single page is polished, so the foundation is solid before anything is built on top of it.

The brand customers will live with

Considered, elevated, and built to last. The platform beneath it should feel exactly the same.

03 The integration architecture

Where the
real work lives.

Your brief maps eight system-to-system flows. Below is our read on each: what it does, and which phase it belongs in. The colour-coding is deliberate. The amber flows are launch-critical. The muted flows are operational leverage we recommend building once you have live orders moving through the system.

01
ShopifyCin7 Core
Order & inventory sync with order-type tagging
The spine of the operation. Orders flow to inventory tagged in-stock, MTO, or backorder, with fulfilment status syncing back. This is the most critical and most delicate integration in the brief, so we build and prove it first.
Phase 1 · Launch critical
02
Cin7 CoreShippit
Freight booking & label automation
On pack completion, order data pushes to freight: carrier selection, label generation, manifesting, and tracking writeback. Native between Cin7 Core and Shippit, with proper handling for oversized furniture freight.
Phase 1 · Launch critical
03
ShopifyKlaviyo
Order-type-specific customer flows
Order events trigger the right communication based on type. An in-stock buyer and an MTO buyer should never receive the same email. Built on Shopify Flow so each order type routes to its own sequence.
Phase 1 · Launch critical
04
ShopifyXeroviaA2X
Automated accounting reconciliation
Revenue, fees, tax, refunds, and COGS posted to Xero as clean journals that reconcile to the bank deposit. Low-risk, high-value. Your finance side stays accurate from the first order.
Phase 1 · Launch critical
05
ShippitKlaviyo
Delivery-driven customer messaging
Dispatch, in-transit, out-for-delivery, and delivered events trigger personalised email and SMS. Reduces "where is my order" enquiries, the single largest support category for furniture.
Phase 1 · Recommended
06
MTO OrderCin7 PO
Automated purchase-order triggering
A confirmed made-to-order sale automatically raises or flags a draft purchase order in Cin7 within 24 hours. Genuine operational leverage, best built once your MTO volume and supplier rhythm are established.
Phase 2 · Operational leverage
07
ShippitSupport
Delivery-exception auto-ticketing
Address errors, failed deliveries, lost or damaged freight automatically create and tag support tickets. Valuable, but only once daily order volume makes manual exception handling impractical.
Phase 2 · Operational leverage
08
YotpoSupport
Low-rating review escalation
One and two-star reviews automatically create support tickets for follow-up, so an unhappy customer is reached before the review hardens. Native to Yotpo, switched on when review volume warrants it.
Phase 2 · Operational leverage
04 Your system map, live

The deliverable,
before day one.

Your brief asks for a system map showing how every platform connects and what triggers what. Rather than describe one, here it is, working. Hover any system to trace its connections. This is a live preview of the documentation you'll own at handover.

The connected operation
Eight systems, one spine
  • Hover any system to trace what it connects to and what each link triggers.
  • Solid lines launch with Phase 1. Dashed lines are Phase 2 automation.
Phase 1 · at launch
Phase 2 · post-launch

Tap a system on mobile.

05 The order-routing logic

Three order types.
Three journeys.

The heart of your brief is that In-Stock, Made-to-Order, and Backorder cannot be treated the same. Each needs its own path through inventory, production, freight, and customer messaging. Choose an order type to watch how it routes through the connected systems.

06 Designed around the product

Built around
the way it's made.

Your range is considered, modular, and made to order. The platform has to understand that from the first pixel: product pages that hold many variants without feeling cluttered, lead times shown honestly, and a structure ready for the configurator when it comes. We design the build around the product, not the other way around.

07 What could go wrong

The three risks,
named upfront.

Every build of this kind carries real risk, and most of it sits in the same few places. We'd rather name them now than discover them together in November. Here are the three most likely to bite on this project, and exactly how we handle each.

01 Inventory sync

Order routing across systems needs a safety net

Once Shopify, Cin7 and freight are all talking to each other, the edge cases live in the handoffs: an order that syncs late, a status that does not write back, a tag that does not carry. Left unmanaged, that is how an order quietly reaches the warehouse wrong.

How we handle it

We use Shopify Flow, Shopify's own automation layer, as the control point. It lets us catch the unexpected coming back from Cin7 and route orders deliberately rather than hoping every system behaves. We map the exact behaviour you want during discovery, then build and prove the routing in a sandbox against real order scenarios before the storefront is touched. It is the first thing we build, not the last.

02 Product modelling

High-variant furniture hits Shopify's limits

Shopify caps a product at 100 variants. Made-to-order furniture across size, fabric, configuration and finish can quietly exceed that, and the excess variants simply fail to appear, a problem that surfaces late and badly if it isn't planned for.

How we handle it

We model the catalogue around this constraint from day one, splitting high-variant products by a primary attribute and driving the rest through metafields and metaobjects rather than raw variants. Your design studio's PDP design and our product architecture are aligned before build, so the structure is decided deliberately, not discovered mid-launch.

03 Freight

Oversized furniture breaks standard shipping rules

Furniture freight is not parcel freight. Dimensional weight, two-person delivery, depot restrictions and bulky-item surcharges all apply, and a checkout that quotes parcel rates will quietly erode margin on every order.

How we handle it

We configure Shippit specifically for bulky freight, with carrier rules and vehicle types matched to your product dimensions, validated against your actual SKU range before launch. Freight logic is tested with real dimensions and destinations, not assumed, so the rates customers see reflect what delivery actually costs.

08 Recommended stack

The right tools for
where you are.

Your proposed stack is well-researched. We agree with most of it, and have two considered recommendations that save meaningful money at launch without compromising the architecture. You asked for guidance, not just agreement, so here it is.

Commerce Shopify Custom semi-bespoke theme built to the Corda. Figma. Structured for the full catalogue and high-variant MTO product pages. Launch on Advanced, not Plus. Move to Plus when revenue justifies it, and we'll tell you when.
Inventory / ERP Cin7 Core Order sync, allocation, pick/pack, fulfilment writeback, and the manufacturing layer that drives MTO production. Core, not Omni. Built for made-to-order brands with a Xero back-end, at roughly half the run cost.
Freight Shippit Multi-carrier booking, label automation, manifesting, branded tracking. Handles oversized furniture freight natively. The retail-focused choice. Best fit for D2C delivery experience.
Email & SMS Klaviyo All transactional and lifecycle flows, routed by order type, built on the EDM templates from your design studio. Agreed. The right platform for high-AOV lifecycle marketing.
Reviews & UGC Yotpo Reviews, ratings, photo and video UGC, visual gallery, with native Klaviyo and support integrations. Pro tier for visual UGC, important for a premium furniture brand.
Customer Support Gorgias Shopify-native helpdesk. Agents action refunds, edits and cancellations inside the ticket, with order context attached. Our suggestion over Zendesk: native to Shopify, faster to set up, more cost-effective at your size.
Accounting A2X → Xero Automated journals: revenue, fees, tax, refunds and COGS, reconciled to each payout. Clean books from order one. Agreed. The standard for accurate Shopify-to-Xero accounting.
Integration glue Flow + iPaaS Shopify Flow handles tag-based routing natively; a lightweight automation layer covers the custom webhook flows. Avoids costly enterprise middleware you don't need yet.
09 Our recommended approach

Live for Boxing Day.
Automated after.

01
Phase One · The launch platform

Everything you need to open the doors, properly.

Aug to Dec 2026 · Live for Boxing Day

A complete, design-complete Shopify store with the integration foundation that matters on day one. The order-routing spine, freight, lifecycle email, reviews, support and accounting, all connected, documented and handed over. This is a brand that can take its first thousand orders without a single manual workaround.

$58,000 + GST, indicative
  • Custom Shopify theme built to the Corda. Figma
  • Full catalogue: Living, Dining, Bedroom, Outdoor
  • High-variant MTO product pages with lead-time display
  • Shopify → Cin7 Core order & inventory sync, order-type tagging
  • Cin7 Core → Shippit freight & label automation
  • Klaviyo lifecycle flows, routed by order type
  • Shippit → Klaviyo delivery messaging
  • Yotpo reviews & visual UGC
  • Gorgias support setup with Shopify context
  • A2X → Xero accounting automation
  • Full technical documentation, system map & credentials handover
02
Phase Two · Operational automation

The leverage layer, once you're trading.

Q1 to Q2 2027 · Post-launch

The advanced automation that compounds in value once real orders are flowing. We recommend building this with live data in hand, so each automation is shaped by how Corda actually trades rather than how we assume it will. Scoped precisely once Phase 1 is live.

Scoped separately
  • MTO order → automated Cin7 purchase-order triggering
  • Shippit → support delivery-exception auto-ticketing
  • Yotpo → support low-rating review escalation
  • Advanced post-purchase & delivery flow expansion
  • Middleware hardening: monitoring, retries, idempotency
  • Optional: product configurator, once launch data justifies it
03
Ongoing · Partnership

A named partner, not a ticket queue.

Post-launch · Monthly retainer

A monthly retainer with defined hours and clear SLAs for response and resolution. Continued development, Klaviyo optimisation, performance monitoring, and strategic counsel as Corda grows. One named point of contact who knows your build inside out.

From $3,500 / month
  • Defined monthly development & strategy hours
  • Agreed SLAs on response & resolution time
  • Klaviyo reporting & ongoing optimisation
  • Performance monitoring & tech recommendations
  • Priority access, no agency queue
10 Why the investment is the investment

At 200 orders a month, a system that isn't properly connected doesn't cost you a line item. It costs you the same amount every single month, quietly, forever.

0 Weeks a customer waits for a made-to-order sofa when the order never triggered a supplier PO. They didn't get a delay. They got nothing, and they don't know yet.
0+ hrs Per month lost to manual workarounds like re-keying orders, chasing tracking and reconciling stock by hand, when eight systems don't talk to each other.
$0 A single mis-shipped or mis-quoted furniture order can cost more than its own value once return freight, restocking and a lost customer are counted.

This is the case for building it properly, once. The Phase 1 investment is not the cost of a website. It is the cost of never running this operation by hand. Every order, from the first, flowing to the right place with the right message, without a person holding it together. Measured against a year of manual workarounds, it pays for itself well before Boxing Day is over.

11 How we'd work together

Structured the way
you asked for.

Engagement model

  • Fixed-price initial build against a scoped Statement of Work, agreed upfront before any code is written.
  • A named lead developer and solutions architect assigned to Corda for the build and beyond, your single point of technical escalation throughout.
  • Monthly retainer post-launch with defined hours and explicit SLAs, so you can manage expectations on fixes and response times.
  • Collaboration with your design studio through UX/UI, so the Figma handover translates faithfully into a built store.

From brief to build

  • Discovery and technical specification. We turn your SoP documentation into a precise technical spec and Statement of Work.
  • Integration sandbox first. The Cin7 order-routing layer is proven in a test environment before the storefront is built.
  • Build in sequence. Storefront and launch-critical integrations, validated against real order scenarios.
  • Documentation as we go. Integration logic, webhook configuration, API connections and a full system map, delivered as a handover pack you own.
12 What we'd need from you

A build is a
partnership.

The Figma, when it's ready

Developer-ready, with named frames and design tokens, from your studio. We'll work alongside them through UX/UI so the handover is clean.

Supplier lead times

Real production and freight timeframes per category, so the made-to-order messaging and PO logic reflect how you actually operate.

System access

Admin access to the platforms as we connect them. You'll own every credential and API key, documented and handed back at the end.

One decision-maker

A single point of contact on your side who can make calls quickly. Momentum is what protects a Boxing Day launch.

14 Why Sonder Sites

Small studio.
Senior hands.

The person you brief is the person who builds

You asked for a single named developer and solutions architect on your account. With us, that's not a concession. It's the model. No hand-off to a junior after the pitch, no account managers between you and the work.

We've built on this exact stack

Shopify, Cin7, Klaviyo, Shippit, working together. We know where the Cin7 connector strains, how to model high-variant products around Shopify's limits, and which flows earn the most. You're not paying us to learn on your project.

Honest about scope and risk

The brief is bigger than a single budget line, and we've said so plainly rather than quietly under-delivering. You'll always know what's launch-critical, what can wait, and where the genuine risk sits.

Melbourne-based, owner-operated

Same city, same timezone, no offshore lag. When something needs a decision or a fix, you reach the person responsible, and it moves in hours.

The next step, on us

We'd normally charge for discovery.
For Corda, it's included.

A proper discovery is where a build like this is de-risked: turning your SoP documentation into a technical specification, pressure-testing the integration architecture, and confirming exactly what each system needs to do. We run this as a paid engagement for most clients. We'd like to include it at no cost here, because we want this one and we'd rather earn it by showing you the thinking than by talking about it.

Discovery, normally $5,000 Included free

Every figure in this proposal is indicative, scoped from what we have today and the Boxing Day timeline. Once discovery is done and your Figma is in hand, we'll convert it into a fixed Statement of Work with confirmed pricing.

Let's scope it
properly.

The shape is here. The pricing is indicative, based on the brief in front of us and the urgency of a Boxing Day launch. The next step is the discovery above: a short working session that turns all of this into a precise Statement of Work, with the numbers confirmed.
